Description
The application is, and to be December 6 calendar year 2001, application number the applying date be " 01822104.1 ", denomination of invention dividing an application for the application for a patent for invention of " orthogonal frequency division multiplex signal receiving system ".
Technical field
The present invention relates to the ofdm signal transmission system for DTB Digital Terrestrial Broadcasting, the ecommerce of communicating by letter with utilization.
Background technology
Irrelevant with the type of transmission path such as satellite, cable and ground, in recent years, be digitized just more and more in the broadcasting of worldwide program map.In these digit broadcasting systems, European and Japanese digit broadcasting system has used Orthodoxy Frequency Division Multiplex (hereinafter referred to as " OFDM ") transmitting system.
The orthogonal a plurality of carrier waves of information modulation, multiplexed those modulation signals and transmission multiplex signal that the utilization of OFDM transmitting system will send in each symbol interval.When the number of employed carrier wave increased, it is very long that the symbol interval of each modulation signal becomes, and therefore, the OFDM transmitting system is characterised in that, it is not easy to the impact that disturbed by multichannel.
In addition, the OFDM transmitting system provides the redundant interval that is called " protection interval " for each symbol interval, thereby, prevented the interference between the code element, and, anti-multichannel interference further improved.Because the symbol interval of ofdm signal is very long and can causing that owing to having increased redundant interval the minimizing of transmission capacity is limited in the permissible range, therefore, can provide so redundant interval.
Fig. 1 is the schematic diagram that shows the configuration of ofdm signal.Hereinafter, the required interval of transmission information is called " effective code element interval " and the effective code element interval is added that the protection interval is generically and collectively referred to as " symbol interval ".Shown in the hachure among the figure, the protection interval of ofdm signal is the circulation copy of the decline (copying part) at effective code element interval.
Then, Fig. 2 has illustrated how the protection interval improves anti-multichannel interference.Desired signal among the figure or inhibit signal represent to differ the ofdm signal that time τ arrives, and G1 and G2 represent respectively the protection interval of the first and second code elements, and S0, S1 and S2 represent respectively the effective code element interval of the 0th, the 1st and the 2nd code element.Here, desired signal and inhibit signal receive different code elements during interval A and interval B, and receive same signal during the C of interval.That is to say, as long as time difference τ is shorter than the protection interval, the interference between the code element that is caused by inhibit signal still remains within the protection interval, will never the effective code element interval of desired signal be had a negative impact.
The OFDM transmitting system as the transmitting system of DTB Digital Terrestrial Broadcasting so that can realize using the SFN (single frequency network) of single frequency structure delay network by utilizing the interfering feature of this high resistance multichannel, and frequency of utilization resource effectively.
Fig. 3 (a) has shown and utilizes the high power relay station to construct the situation of extensive SFN, and Fig. 3 (b) has shown the on a small scale situation of SFN of low-power relay station structure of utilizing.Fig. 3 (a) is compared with Fig. 3 (b), and the distance among Fig. 3 (a) between relay station 1A and the relay station 2A is larger, and broadcast singal is also larger from the time difference that each relay station arrives acceptance point 3A.Therefore, the extensive SFN shown in the structural map 3 (a) need to be than the longer protection interval of small-scale SFN shown in the structural map 3 (b).
But; taking long protection interval needs the therefrom redundancy time of increase, and, for all the increase symbol intervals based on the OFDM transmitting system; when broadcasting high definition TV (hereinafter referred to as " the HDTV ") vision signal of large information capacity, reducing transmission capacity can go wrong.
Therefore, when making because the minimizing of constructing the transmission capacity that the required protection interval of extensive SFN causes drops to when minimum, it is favourable taking than the long symbols interval.
On the other hand, the DTB Digital Terrestrial Broadcasting system of Japan adopts match keying (hereinafter referred to as " DQPSK ") or disperse data time-interleaved of adjacent code element in time of difference four, modulating system as each carrier wave, thereby, even under the mobile unit reception environment that changes, also make stable the reception become possibility in time in the transmit path characteristic.
In this case, shorter symbol interval is not easy to be subjected to the impact of time variation, and, even during high-speed mobile, also can provide stable receptivity.
Therefore, when utilizing extensive SFN broadcasting HDTV video image, perhaps, when to the broadcast service such as mobile unit of high-speed mobile, best code element gap length changes with service content.
For such requirement is responded; as shown in Figure 4; the DTB Digital Terrestrial Broadcasting system of Japan provides the pattern of the different three types of effective code element gap length, and the protection interval that Four types is provided for every kind of pattern is than the ratio of effective code element gap length (the protection gap length with).From then on begin, this altogether 12 types combination is called " transmission mode ".In these types, for example, the protection interval in the mode 3 than 1/8 with the protection interval than the 1/4 identical protection interval with 126 μ s (microsecond).
In case the position of the relay station in broadcasting station is determined, just can estimate broadcast singal from the maximum of required time difference of the acceptance point in each relay station arrival service area, and, from this numerical value, determine necessary protection gap length.This numerical value is different because of junction network, and therefore, the effective code element gap length that is accompanied by can change with area or broadcasting station etc.
In addition, when the protection gap length of being determined by relay station is, for example, during above-mentioned 126 μ s, the broadcasting station can be selected and be arranged to 1/8 to the protection interval ratio under the mode 3, still should be arranged to 1/4 to the protection interval ratio under the pattern 2.At this moment; also can depend on the service content of program; between these two kinds of transmission modes, switch; for example; program for broadcasting HDTV image utilizes the protection interval under the mode 3 to increase transmission capacity than 1/8, and for the program that is the mobile unit broadcast service; utilize protection interval under the pattern 2 than 1/4, stably service is offered the high-speed mobile unit.
In addition, after broadcast service began, when the distance between the relay station shortens when diminishing with the above-mentioned time difference because of the adding of relay station, necessary protection gap length also diminished.But, because the protection interval is to be originally unnecessary redundant interval for information sends, therefore, from the viewpoint of effective frequency of utilization resource, certainly the protection gap length is changed over minimum necessary length.
As implied above, by changing effective code element gap length and protection interval with area or broadcasting station than the transmission mode of combining expression, and certain broadcasting station also can change in time.
On the other hand, demodulation process to ofdm signal on the recipient is only extracted the required interval of demodulation from receive signal, fast fourier transform (hereinafter referred to as " FFT ") is applied to signal, thereby, separation is by the carrier wave that sends after multiplexed, then, according to each carrier modulation system, use Check processing.In the process of that processing, the transmission mode that is that compares such as effective code element gap length and protection interval consists of requisite information.
Therefore, when the transmission mode that receives signal was unknown, the method by information processing above-mentioned transmission mode of automatic acquisition from receive signal itself was disclosed in No. the 2863747th, patent gazette or the patent gazette the 2879034th etc.
To have utilized the protection interval of ofdm signal be the fact of the circulation copy of the signal on the effective code element space ends to disclosed prior art in these documents; calculate to receive signal and the correlation between the signal of the effective symbol interval length of receiving signal delayed estimation gained; analyze the waveform of this coherent signal; thereby, judge effective symbol interval length and protection gap length.
Traditionally, people utilize the communication network such as the internet to implement various ecommerce, for example, buy product.In such ecommerce, the product that conclude the business is published in, for example, on the homepage.The user is by the internet, and from his/her this homepage of terminal access, the product that selection will be bought simultaneously, is inputted identification user's user profile.
Then, the user inputs credit number and ID (identifier) between the accounting period, and specifies the clearing form such as cash on delivery.In case finished such project, homepage travelling mechanism (center) is just authorized the product order is made arrangements, and the supplier who receives order consigns to the user to product, and collects money according to the clearing form of appointment.
But, according to the transmitting system of utilizing above-mentioned ofdm system, receive ofdm signal, then, determining transfer mode from receive signal, therefore, after the user selection information needed, until the time that the user receives between the information has comprised the time of making above-mentioned judgement, this has hindered makes quick response to customer requirements.
And, when as described, the broadcasting station is according to the service content of program, when switching between transmission mode, demodulation process is at once interim interruption after conversion, and, before the transmission mode decision process is returned from that recovering state and is obtained court verdict, can not export converting transmission pattern information afterwards, therefore, user's information supply can be ended for a long time.
In addition, utilize the above-mentioned ecommerce of communication network to involve the problem relevant with complexity with the confidentiality of settling accounts.With regard to the confidentiality of using credit card, worry be the problem such as to be forged.With regard to clearing, settlement process is simpler, and security reliability is just lower.On the other hand, attempt to guarantee that confidentiality is convenient to again settle accounts the scale that will cause system configuration and increases.

This embodiment hypothesis mainly is used in when transmission mode and changes with area or broadcasting station etc., and transmission mode is not when changing within the short time such such as program cells, in the mobile reception environment such as automobile and cellular phone.
In addition, this embodiment utilization channel different from broadcast channel sends the programme information that comprises transmission mode information, and when selecting channel, uses this information.
In Figure 12, programme information distributing center 50 obtains/stores the programme information from broadcasting station 60 by communication channel 40, and, according to the request from digital broadcasting receiving apparatus 10D, distribute programme information.
On the other hand, different from the first to the 3rd embodiment, under the prepattern that is not in as operating state, digital broadcasting receiving apparatus 10D also can provide user's information needed.
Figure 13 is the flow chart that shows the operation of the CPU107 among the digital broadcasting receiving apparatus 10D;
At first, give the user (step S20) menu displaying by output 105.When the user wants digital broadcasting (step S21, S23), digital broadcasting receiving apparatus 10D utilizes radio communication I/F part 114 and radio communication antenna 113, and the request that programme information is distributed is sent to programme information distributing center 50 (step S23).At this moment, utilize the Location Registration Function of explanation in embodiment 3, not only circulate a notice of this request, and the circular current location.
In case by radio communication base station 30 and communication channel 40, receive distribution request and current location from digital broadcasting receiving apparatus 10D, programme information distributing center 50 is just by communication channel 40 and radio communication base station 30, relevant can be in the information distribution of the program current location reception, that the broadcasting station is supplied to digital broadcasting receiving apparatus 10D (S23).
CPU107 among the digital broadcasting receiving apparatus 10D is by radio communication antenna 113 and radio communication I/F part 114, obtain programme information from programme information distributing center 50, information is stored in (step S24) in the storage area 108, and shows the tabulation (step S25) of the program that can receive in current location by output 105.
Then, when the user selects required programs from above-mentioned tabulation (step S26), CPU107 obtains the channel selection information corresponding with top program (step S27) from storage area 108, frequency channels is sent to tuner 102 (step S28) and transmission mode information is sent to OFDM demodulation part 103 (step S29).
Figure 14 has shown the content of programme information.In this example, for each program, programme information comprises as the title of content information and type, as the frequency information of channel selection information and transmission mode information with as time started and concluding time of temporal information.
The above-mentioned configuration of this embodiment is not so that not only can be in the situation that there is initialize operation, the program of user selection is provided, and even under the mobile reception environment that current location at every moment changes, also can utilize based on less than mobile radio in Location Registration Function, the identification current location, this makes the user not need motion according to mobile unit, and input message is identified current location continually.
By the way, if being arranged to distribution, system also comprises in advance certain hour, for example, within 24 hours or the programme information of the timetable within the week, with digital broadcasting receiving apparatus 10D content is stored in the storage area 108, so, this user subscribe required programs and program at first automatically the operation of broadcast program also be feasible.
In addition, the present embodiment has been described channel selection information and program has been interrelated, as programme information, but, although may change with area or broadcasting station etc. in transmission mode, but in the situation that transmission mode did not change within the short time such as a program cells, programme information distributing center 50 also can distribute the channel selection information relevant with the broadcasting station, with in the situation of the first to the 3rd embodiment, digital broadcasting receiving apparatus 10D also can be assigned to information button of importation 106 etc.
In addition, if transmission mode sends change after such appointment, perhaps, if current location and move and change, digital broadcasting receiving apparatus 10D tells the user not receive with request program information distribution center 50 by output 105 and redistributes information, show new tabulation and upgrade appointed information, thereby more convenient can bring to the user.
(5) the 5th embodiment
The 5th embodiment will describe the transmission information control that the transmission information control section that is made of CPU carries out.Control and the prediction of the FREQUENCY CONTROL of transmission information, the time control such as how long having passed through after using, channel region identification service content etc., utilize the Information Compression etc. of pattern information to be described in detail.Transmission information is included in from the transmission data of the cellular phone of base station with among one of the transmission data in TV (TV) broadcasting station or both.The present embodiment will be described from the example of the information of cellular base stations transmission.
(5-1) overall arrangement
Figure 15 is the overall pattern that shows the relation between TV reception type cellular phone 501, ground TV platform 502 and the cellular base stations 503.Ground TV platform 502 uniaxiallies send to cellular phone 501 to broadcast singal 504 downwards, and cellular phone 501 receives a part of data of the particular channel of this broadcast singal 504.Broadcast singal 504 also is sent to the fixed reception device that contains fixed antenna 514, i.e. digital TV receiver 505.
(honeycomb fashion reception) on the other hand, TV reception type cellular phone 501 receives as down link signal 506,506a or 506b from the signal of one cellular phone 501 or several cellular base stations 503,503a or 503b near, and uplink signal 507,507a or 507b is sent to any one or several stations of cellular base stations 503,503a or 503b.Cellular base stations 503 is connected with common network 511 by cellular phone control section 510.In the situation of special cellular telephone services company, cellular phone control section 510 is connected with internet 513 by server 512.
(fixed reception) as mentioned above, sending data also by such as the TV of family, contain in the situation that the TV receiver 505 of the digital TV of highly sensitive fixed antenna 514 receives, receive all data in the particular channel, rather than above-mentioned part broadcast data.Some TV receivers 505 are connected with local landline telephone station 515 by telephone wire, and, can pass through common network 511 access the Internet 513.
Receive between the condition of acceptance of above-mentioned digital TV broadcasting data and the condition of acceptance by fixing above-mentioned digital TV broadcasting data of TV receiver 505 receptions by cellular phone 501 and to have very big-difference.When receiving the digital TV broadcasting data by TV reception type cellular phone 501, receiver is mobile.When receiving above-mentioned SFN (single frequency network) channel broadcast data, the receiver picture as shown in Figure 16, move to another place from a place, even receiver moves in the service area in next broadcasting station, it also receives contains TV signal identical information, that have same frequency, and therefore, what trouble receiver can not run into aspect the TV reception yet, continue to receive broadcast data without ground, any slit, and its movement can not cause any problem yet.
But, in the situation of the broadcast data that receives non-SFN channel, move to the process of position 5 from position 1 (Figure 16) at receiver, owing to weakening of field intensity, in certain point of position 2 and position 3, utilize the receiver of conventional method can not receive signal from 1TV platform 502.
Therefore, when attempting to search for the channel corresponding with broadcast data, the user of TV reception type cellular phone utilizes the tuner switching frequency.Then, the user knows existence 2TV platform 502a at last, and, attempt receiving broadcast data.But in the situation that digital TV broadcasting is different from analog broadcasting, receiver can not only pass through tuned frequency, manages to receive signal.In the situation that the transmission information parameter that does not make such as protection interval and error correction coding mates again, can not receive physical layer.For this reason, traditional TV reception type cellular phone changes parameter in every way in the circulatory system (round-robin system), and it is only attempting to find out which parameter.
There are tens of kinds to thousands of kinds parameter combinations.For this reason, parameter matching to be taken time.After the demodulating information of the ground floor that to receive signal, can demodulation second and more high-rise, therefore, can acquired information.Owing to determining by this way with reference to will taking time, therefore, if comprise several frequencies, so, do not have TV receive signal can period of output between, exist, for example, several seconds, at most to time interval of tens seconds.The channel of managing to receive signal at receiver does not have in the situation of the required service of broadcasting user, and the user is transformed into one other channel, continues the service that search subscriber is selected.In this case, determine that parameter also will take time, therefore, take more extra time.
The present invention receives base station IDs at least from the down link signal 506 of cellular base stations 503, obtain positional information from base station IDs, obtains the transmission information of the parameter that comprises the modulation signal of broadcasting for demodulation TV from positional information, and this signal of demodulation.Perhaps, by reading the transmission information with the corresponding area property TV of the base station IDs broadcasting station that utilizes transmission information to control database to obtain, the present invention can skip the channel demodulation process, the transmission information pre-recorded correspondence table in cellular phone of controlling database.Therefore, can shorten channel time of reception or channel switching time.
Here, Figure 17 has shown the calcspar of the configuration of cellular base stations 503.Base station 503 comprises cellular base stations antenna 516, base station sending/receiving circuit 517, at lower be attached thereto by channel, the Control on Communication part 518 that is called " RNC (radio network controller) " and PDSL that is connected with backbone 519 (the Panasonic soft laboratory of numeral) 520 such as ATM (asynchronous transfer mode).These all are to communicate required square by cellular phone.
The data that cellular base stations 503 sends as shown in figure 18.That is to say, comprise base station IDs 521 or basic station number 521 as the cellular phone data 523 as essential information under the communication pattern among the cellular phone data 522 of the essential information that sends data under the standby mode and Figure 18 (b) among Figure 18 (a).Therefore, in all cellular telephone services districts, can receive base station IDs, and this base station IDs can be as the supplementary of TV reception.
In addition, base station 503 according to the present invention sends TV and receives part or all that required TV receives transmission information data 524.In the situation that this sends information, also can be included in the transmission information in another broadcasting station in the TV broadcast singal and send.In this case, achieve success in case TV receives, just can obtain the transmission information in other radio station, therefore, those similar effects in the situation that can obtain to send to the base station.But, in case receiving, ends TV, require the information of relevant base station.
(5-2) explanation of the first and second transmission information
TV receive data 524 among Figure 18 is described now.Figure 19 is the flow chart that shows the particular content of this TV receive data of deferring to ISDB (Integrated Services Digital Broadcasting)-T standard, and the ISDB-T standard is that Japan is based on the digital TV broadcasting standard of OFDM.TV broadcast standard based on OFDM such as the DVB standard also has similar parameter.
Figure 18 (a) has illustrated that cellular phone is in the transmission data under the standby mode, used the first high resistance channel with cellular phone, and, cellular phone data 522 sent, that is, the base station IDs 521 of identification base station and the data of free cellular phone communication channel.In addition, as mentioned above, also send the required TV receive data 524 of tuning/demodulation digital TV broadcasting according to cellular base stations of the present invention.
TV receive data 524 comprises the transmission information 528 of the channel in the current TV broadcasting station among sending of indication.Transmission information 528 comprises the channel id of current all channels among sending.Channel 527 among sending is received, and the receiving platform that not only is fixed uses, and is used by train and automobile.When part broadcasting was exclusively used in T pattern cellular phone, the part broadcasting that is limited to the channel id in the current broadcasting station that service is provided had the effect that reduces amount of information.
The situation of ISDB-T standard is used as an example and shows.Shown in Figure 20 (a), because HD (high definition) broadcasts-has a channel of identical transmission resistance and high-resolution TV broadcasting, or SD (single-definition) broadcast data 528 of 4 to 5 channels of broadcasting-having the TV broadcasting of normal resolution is to utilize a broadcast band for the broadcast transmission of 6MHz or 8MHz, therefore, can use channel 527 among sending.
But in this embodiment shown in Figure 20 (b), one or two particular fragments 529 of 13 sections has the resistance than other common section the last 530.For example, by from 64QAM (quadrature amplitude modulation) as modulating system be used for common section different, QPSK (quadriphase PSK) is used for particular fragments, perhaps, from different for common section as FFT length 8K, 2K is used for particular fragments, changes parameter and the information of reduction transmitting efficiency, resistance is strengthened.
This embodiment claims this laminated devices to broadcast as " part sends " or " part broadcasting ".Because segmentation 529 utilizes the broadcasting of resistance parameter, therefore, even by the small size antenna such as the antenna 531 (Figure 21) of cellular phone, also can receive segmentation 529.On the other hand, in the situation of part broadcasting, because the frequency band that uses is narrow, and transmitting efficiency is low, sends data capacity and suddenly drops to slightly more more than 1Mbps from Mbps up to a hundred.
But, in the situation of the mobile device such as cellular phone, display screen is little of 1 inch to several inches, provide low transmission rate from tens Kbps to hundreds of Kbps with use, and the MPEG4 of high compression ratio or microwave system can provide the screen quality that can not cause any audiovisual trouble.
In addition, shown in Figure 20 (c), utilize the data broadcast of single hop 532 or 3 sections to define by ISDB-T, and in the situation of " part sends ", this also is applicable to honeycomb fashion and receive.This standard comprises that also this data under " part sends " send.
According to Figure 18, for the cellular phone that carries out such mobile unit reception, transmission information 528 comprises the data of the channel 533 among the transmission of above-mentioned part again.Only have the channel number (hereinafter being abbreviated as " ch ") that is being broadcasted just to indicate the frequency band of appointment in each country.For example, be enough to apart to prevent that in another zone with broadcasting 15ch different broadcasting stations utilize identical channel in the zone of distance of phase mutual interference, namely identical frequency provides and finishes different broadcast service.
Because mobile unit is mobile, utilize the TV reception of cellular phone to require two radio station are all identified.Therefore, add identification information 534, utilize the broadcasting station of same channel with identification.Before adding identification information 534, can not identify each broadcasting station.For example, even same 15ch is defined as, for the previous broadcasting station among the regional A, 15-1ch, for the rear broadcasting station among the regional B, 15-2ch, also not all right.
Therefore, by add the identifier that can identify the identical different broadcasting stations of frequency for zones of different, define the information in each broadcasting station so that can utilize identical frequency band, that is, and the broadcasting station of identical channel identification zones of different.Like this, can prevent because the broadcasting station of wrong identification same channel is provided with the wrong misoperation that parameter causes that sends.
In addition, base station according to the present invention sends field intensity information 535 for each channel.Receiver can be controlled this information, selects the higher receive channel of priority from the strong channel group of field intensity, and more stable reception is provided.
Then, utilize Figure 18 and Figure 19 to describe the required transmission information of demodulation in detail.Such as Figure 18 or shown in Figure 19, the transmission frequency 536, part broadcast identifier 550, FFT length 537, indication code elementary time that the first transmission information 526 comprises the channel that indication will send and the protection interval of the ratio at protection interval are than 538 and the transmitted power 539 of broadcast antenna.
As shown in figure 19, by the first transmission information 526, can know the various parameters before broadcast singal or demodulation.For this reason, by means of the setting of the first parameter, demodulation is by the data of the ground floor of the layer of OFDM or PSK transmission.Simultaneously, can be from from the data of ground floor demodulation, obtaining the demodulating information 541 of the demodulation second layer, for example, the TMCC data of ISDB-T standard or the TPS data of DVB standard.This demodulating information makes all data can obtain demodulation.
In the situation that the mobile unit that is used for the application such as cellular phone and automobile receives, because these mobile units pass several service areas in broadcasting station, the parameter of the first transmission information 526 often changes.When first sends the unknown parameters of information, except attempting to arrange all parameters according to the circulatory system and attempt the demodulation, other way never again.Owing in the situation of ISDB-T standard, always having 12 kind of first combination that sends information, must carry out the most nearly 12 times setting operation, to determine the parameter in the ground floor.For this reason, the output receive data will be taken time, and the present invention has the effect of the data in the instantaneous reproduction ground floor.
Because these data in the ground floor comprise the demodulating information 541 that contains from the second layer the required parameter of demodulation layer signal forward or error correction etc., therefore, when the first step back of demodulation ground floor is followed the second step of demodulation demodulating information 541 and during the third step of extracting parameter, can utilize the demodulating information 541 demodulation second layers from demodulating information.
But as mentioned above, in mobile the application, the parameter that sends information often changes.If can know in advance the demodulating information 541 of this second layer, so, can obtain all and send parameters, therefore, even demodulating data quickly.To utilize now Figure 18 and Figure 19 that this high-speed demodulating system is described.Figure 18 (a) is under standby mode, sends the two system of the first transmission information 526 and the second transmission information 525 from cellular base stations.
At first, effect once is described.Under standby mode, the base station sends transmission information.Therefore, such as PDS (personal digital assistant) and portable TV, there is not up link, that is, the portable terminal of transmitted power can receive this information, therefore, this system has when receive data first, or when channel changes, significantly shortens the effect of time of reception.
In some countries that comprise Japan, forbid aboard or in hospital, use such as cellular phone the equipment transmitted signal with transmitted power, but, even under these circumstances, if utilize switch pattern to be changed over " T pattern ", in the situation that not from the cellular phone transmitted signal, also can receive and obtain the information of transmission, this has widened the range of application of the broadcast reception of cellular phone.
In addition, before entering the zone that bans use of cellular phone, when connecting the T mode switch, the user sends specific region, work time zone, portable terminal ID by the base station and receives the broadcasting station ID in the broadcasting station of all-calls data to the broadcasting station.Then, when calling out the arrival cellular phone, send the broadcast singal that comprises specific portable terminal ID by the broadcasting station, therefore, detect and call out to arrive particular terminal, tell the user by vibrating motor etc. with it, thereby, reach the paging effect, that is, send and receive announcement.
Comprising under the T pattern of calling system of the present invention, do not send the intense radiation radio wave, this has the total radio wave amount and the effect of reduction radiate radio waves on the impact of human body that reduces from the cellular phone emission.
To illustrate now by making their medellings control send the method for information parameter and compressed information.According to the second transmission information among Figure 18 (a), the second transmission information 525 comprises the parameter such as modulating system 551, encoding rate 552, time-interleaved length 553, and these parameters are different because of channel.More particularly, shown in the Lower Half of Figure 19, in the situation of ISDB-T standard, three kinds of pattern: DQPSK, the 16QAM and the 64QAM that have modulating system 551, five kinds of patterns of encoding rate 552 such as error correction Viterbi encoding rate, with four kinds of patterns of time-interleaved length 553, altogether provide 60 kind of second parameter combinations that sends information.
Have 12 kind of first parameter that sends information, and if comprise part broadcast identifier 550, so, always have 24 kinds of combinations, amount to and provide the combination of 64 * 24=1440 kind.In the lower right corner of Figure 19, shown that the parameter of each channel arranges example.But the operation in broadcasting station is complicated in the real digital TV broadcasting, can estimate, special parameter is selected in each broadcasting station from these parameters, therefore, and can be with parameter mode.
Like this, shown in calcspar and the database among Figure 22 among Figure 21, send information control section 556 and select by the descending of the frequency of the first transmission information 526, for example, 16 parameters are selected first mode numbers 554, and those reference records in sending information data storehouse memorizer 557.Equally, the second transmission information 525 is also selected 16 parameters, that is, 4-position parameter, and those reference records in the memory 557 that comprises database 559.
Like this, each broadcasting station can be expressed has a position, 16 * 16 kinds of pattern=8, namely, all parameters of the transmission information of 1 byte data, therefore, if pattern is within this scope, so, even the transmission recording of information corresponding with 1000 radio station in the particular country only needs the memory capacity of 1KB.In the little cellular phone of memory capacity, this has the effect that reduces storage consumption.
Transmission information control section 556 carries out frequency computation part and FREQUENCY CONTROL, and the position in 558 judgement broadcasting stations, position detection part and each radio station of control, and this has improved the parameter hit rate.To illustrate in greater detail later on the operating procedure that this sends management information system.
W-CDMA (Wideband Code Division Multiple Access (WCDMA)) system as the main flow of cellular phone of future generation allows to use in the Asia that comprises Japan and western countries the cellular phone of same type to carry out session.As shown in figure 21, T pattern cellular phone 501 of the present invention contains national test section.For example, when Japanese user comes Europe or the U.S., detect country in can the national information from base station IDs and changed.This detection signal is circulated a notice of to transmission information control section 556, therefore, by changing modulating system, FFT length and the protection space coding rate etc. such as QPSK and QAM, also can be according to the outer broadcast singal of foreign broadcast standard receiving country.
(5-3) explanation of cellular phone
Utilize now the calcspar of T pattern cellular phone 501 among Figure 21, illustrate to comprise the demodulation that is sent in interior down link signal that utilizes cellular phone.The signal that receives from antenna 531 is separated by duplexer 561, by front end 562 and filter 563 filtering, and by demodulator 564 demodulation.Then, by A/D converter 565 signal is converted to digital signal, and the despreading section 566 of despreading CDMA signal is according to the synchronizing signal of sync section 567, Reconstruction of Extended data.This signal is detected by test section 568, carries out Veterbi decoding by data decoder 569, passes through output control part 570, and converts voice signal to by Voice decoder 571.
Then, switching part 572 outputs to loud speaker 573 to voice signal, and perhaps, the LPF (low pass filter) 574 by allowing your band signal pass through outputs to ear port 575.By earphone 576 is connected with this ear port, the user can listen to the voice signal of reception.The present invention also receives TV broadcasting etc. to the cord 577 of earphone 576 as antenna, thereby, increased sensitivity.
The broadcast singal that the switching part 579 of TV receiving unit 578 makes reception switches between the signal that receives by portable antenna 531 and the signal that utilizes the earphone cord to receive.In this case, according to the comparative result that signal level rating unit 588 is done, select and export the reception signal with higher-wattage, or the signal that has high C/N value or have low error rate, therefore, in the situation of diversity antenna, obtain optimum receiving signal.Tuner 580 utilizes the frequency tuning signal of particular channel, and demodulation part 582 is from parameter and the restituted signal of the first and second required transmission information (Figure 19) of demodulation control section 583 receiving demodulations.This OFDM demodulation method was once made detailed description, therefore,, omitted the explanation to it here.
The error correction parameter such as the Viterbi encoding rate that error correcting section 584 utilizes as shown in figure 19, reconstruct primary signal from restituted signal.Video Decoder 587 is decoded into vision signal to the MPEG4 that receives from output 586 by output control part 570 or microwave signal etc., and display part 590 shows images by display circuit 589.In addition, secondary display circuit 591 is processed the data-signal in the broadcast singal of being included in from output control part 570, and, it is presented on the secondary display part 592.This flow process will be illustrated in following embodiment.
The now operation of explanation cellular phone among Figure 21 during sending.User's voice convert the signal of telecommunication to by microphone 594, through Voice decoder 595 compressions, are input to channel CODEC (codec) 596.On the other hand, the user utilizes the data of keyboard 593 inputs to be processed by output control part 570, and, in result, the data input channel CODEC596 that will send to the base station.
This coding/decoding output signal is modulated into QPSK etc. by elementary modulator 597, on frequency band, converts analog signal through ROF599 to by D/A converter 600 by expansion 598 expansions, and does further modulation by the modulator 601 that contains oscillator 603.This modulation signal is mixed mutually by the signal of blender 602 with oscillator 604, is amplified by power amplifier 605, through duplexer 561, sends from antenna 531.The operation of the transmitting portion 606 of Here it is T pattern cellular phone 501.
Like this, the reception information that the base station IDs that sends from cellular base stations 503 and receiving broadcast signal are required and demodulating information are received by the receiving unit 607 of T pattern cellular phone 501, and, these data are sent to the transmission information control section 556 of TV receiving unit 578.Then, utilize the data of memory 557 such as sending information database 559, as the Data Modulation channel frequency that utilizes FREQUENCY CONTROL part 581, process or use receive data.Then, be used to explain by oneself the demodulating control signals of regulation and control part 583 processed, divide 585 to utilize the optimal parameter setting of error correction and the instantaneous demodulation that the setting of optimal encoding code check is carried out by decoding control section, the shortest may the time in this signal of demodulation, so just produced the outstanding effect of instantaneous demonstration TV broadcasting, music broadcast or data broadcast content.
If this is the effect of unique requirement, so, the transmitting portion 606 among Figure 21 just there is no need.For this reason, in the situation of general portable type television set, only add the configuration that receiving unit 607 or utilization comprise the TV receiving unit 578 of transmission information control section 556 of the present invention, just can obtain similar effect.
Such as Figure 18 (a) with (b), they have shown that the radiate radio waves of utilizing cellular base stations sends the example of the first transmission information 526 and the second transmission information 525, but, also can send to transmission information 528, the first transmission information 526 and the second transmission information 525 of the channel number in another broadcasting station etc. the separately data field of TV broadcasting or part broadcasting.
In this case, when portable receiver 501 these sides' of Figure 21 middle and lower part calcspar TV receiving unit 578 receives particular channel, from the transmission information in output 586 other radio station of output.The data of channel comprise the transmission information 528 (Figure 18) of channel in other radio station that can receive and the first transmission information 526 and the second transmission information 525 of relevant those channels in this zone.When extracting this in the output 586 from Figure 21 and send information, add the transmission information of channel, and, with its input transmission information control section 556, information recording/in sending information database 559.
During the program in the broadcasting station that is receiving particular channel, when channel is switched to one other channel, from send information database 559, extract the reception information of the channel in this other radio station, transmission information control section 556 arranges the parameter of various piece, carry out tuning, separate the mediation error correction, therefore, can export the channel in other radio station from the output 586 that is provided with the first parameter.
With regard to having produced and having compared with reference to the situation that is the unknown, significantly shorten the effect of the time that is transformed into one other channel like this.In this case, not only send the transmission information in the broadcasting station in the current broadcast service area, and send the transmission information in the broadcasting station in the adjacent broadcasting service area, all make mobile reception more reliable.
In this case, by means of the ID of the base station of containing base station service area, send transmission information, this base station service area is corresponding with the broadcasting service area in the broadcasting station that has specific broadcasting station ID.Receiver is recorded in these data and sends in the information database (DB) 559.Then, ended to move with mobile unit even receive, as long as base station IDs is known, also can have identified to conciliate and readjust the distribution carry information.
But after mobile unit had moved a very long segment distance, when receiving first, that regional parameter was unknown fully.Like this, when the reception termination of TV broadcasting and mobile unit were moving, the transmission information of the base station of cellular phone was absolutely necessary.
Here, three kinds of demodulation methods will be described.First method is at first described.First method is for easy configuration, only has in Figure 21 under the hypothesis of TV receiving unit 578, changes the method for parameter according to the circulatory system.This first method is suitable for cheap portable TV or PDC.
Second method is the method that adds receiving unit 507 of the present invention among Figure 21.So just can receive the ID of cellular base stations.Because the present invention contains transmission information control section 556, therefore, can identify the broadcasting station that service is being provided from base station IDs.Transmission information control section 556 search base station ID, with according to this base station IDs with from time of temporal information part 610, from send information database 559, search for the transmission information of the airtime in the broadcasting station corresponding with the current time, the corresponding date/time transmission information of correlated channels is sent to tuner 580 and error correcting section 584, thereby, even after mobile unit has occured to move, also can the required channel of instantaneous output.When channel changes, use the transmission information of from broadcast singal, downloading or receiving.
This second method that the above had just described and cellular base stations have no relation, and therefore, second method has except broadcasting, does not need the effect of other communications facility.In addition, second method has been used cellular base stations, still, has only used base station IDs, therefore, has the effect of not needing to change existing cellular base stations facility.Even adopted transmission information transmitting system of the present invention, owing to estimating in the whole world tens thousand of cellular base stations are arranged, this system can be supported gradually.In the process of this system of support, exist many base stations of not supporting this system, this is those effective and feasible zones of above-mentioned the second.
For in above-mentioned second method with utilize configuration among Figure 21, from the base station, namely, switch between the third method of back-up system reception transmission information fully, base station IDs test section 611 is detected the cellular signals that receives and is included only base station IDs and do not comprise transmission information, and this detection information is sent to transmission information control section 556.Cellular phone utilizes base station IDs, searches for the transmission information in the broadcasting station corresponding with base station IDs from send information database 557, if find this transmission information, so, parameters and receiving broadcast signal.If do not find this transmission information, so, change and the demodulation parameter setting values according to round-robin method.Receiving mobile first data-signal afterwards will take time, and still, in case receive broadcast singal, just can download the transmission information in other radio station, therefore, even channel has been switched, also can export the reception signal at once.
In this case, connect specific website etc. by utilizing the cellular phone up link, request sends local transmission information and utilizes down link to download transmission information, also can have similar effect.
(5-4) explanation of cellular base stations
Then, utilize Figure 17 that configuration and the operation of cellular base stations 503 are described.At first, overall arrangement is described.Cellular base stations 503 among Figure 17 contains cellular phone antenna 516 and sending/receiving circuit 517, and, be connected with Control on Communication part 518 by the dedicated communication circuits among ATM etc.Several Control on Communication parts 518,518a and 518b in the zones of different is connected with the PDSL520 of cellular phone company 564 by the backbone 519 with large transmission capacity, and, controlled in a concentrated manner.
Then, the configuration of the additional function that contains the required transmission information of the broadcast reception of transmission as TV of the present invention is described.Broadcast receiving aerial 551 is installed in the radio wave that receives this area cellular phone antenna 516 near, the reception signal amplifying part of broadcast reception part 550 is divided 602 amplifying signals and tuner 580 tuning these signals.Allow signal eliminate part 1032, FFT1033, test section 1034 and error correcting section 1035 through quadrature detector 1031, protection interval, export as numerical data.The operation of this part has utilized Fig. 6 to be described, and therefore, omits the explanation to it.
By often carrying out this demodulation for each channel, can obtain the transmission information relevant with optimal parameter tuning and that demodulation is required.Broadcast reception information extraction part 542 among Figure 17 is extracted some or all of these parameters, they is sent to broadcast reception information add part 547.Then; This signal is amplified by transmitting portion 621, and with such as Figure 18 (a) and the transmitted signal of the cellular phone (b) mix mutually.Then, signal is sent to T pattern cellular phone from antenna for base station 516, be used for broadcasting as TV as tuning/demodulating information.
Then, the operation that sends information extraction part 542 is described.At first, transmission information extraction part 542 is the information squares for narrow district, and it calculates field intensity 535Z according to amplification factor and signal level from the output of amplifier section 620.Send information extraction part 542 and calculate this field intensity and distance, obtain the transmitted power 539Z in broadcasting station.From tuning part 580, obtain current transmitting channel 527Z, part broadcast channel 550 and transmission frequency 536Z.From protection interval elimination part 1032, obtain the protection interval and compare 538Z.From FFT part 1033, obtain FFT length 537Z.From demodulating information decoded portion 1036, obtain modulating system 551, the encoding rate such as the Viterbi encoding rate 552 and time-interleaved length 553.In the middle of these parameters, the parameter that sends information extraction part 542 is sent to transmission information and adds part 548, amplified by transmit amplifier 621, and, send to T pattern cellular phone of the present invention by cellular phone antenna 516.Transmission information extraction part 544 is the information squares for wide district, it is made of first information Extraction parts 545 and the second information extraction part 546, and the parameter that sends information extraction part 544 extractions is sent to respectively first of transmission information adding part 549 and sends message part 526Z and the second transmission message part 525Z.Then, by transmit amplifier 621 these parameters are sent to T pattern cellular phone, perhaps, in order to send the programme information of Control on Communication part 518, they are sent to broadcast transmission information processing part 560 temporarily, then, send to cellular base stations 503.
In addition, broadcasting station 563 comprises programme information transmitting portion 562, by channel programme information and transmission information are sent to broadcast transmission information processing part 560, thereby can send to T pattern cellular phone and program downloading information and transmission information by cellular base stations 503.About programme information in this case, identical content is sent to all base stations in the service area, and for transmission information, send different from a base station IDs to another base station IDs or from a base station IDs group to the content different from corresponding another base station IDs group in broadcasting service area.
As implied above, send information parameter the base station can be received independently based on transmission information of the present invention for each cellular base stations is equipped with to obtain near the TV broadcast receiving aerial 551 of cellular antenna and each channel.This can be achieved in this place system, and, have the effect of simplifying system configuration.
(5-5) send information management system
Exist several to send the operator scheme of information management system.The below utilizes each pattern of description of drawings.
(5-5-1) parameter setting
At first utilize the flowchart text first method among Figure 23.In step 650a, at first open the mains switch (SW) of the simulator such as T pattern cellular phone, PDA or portable type TV.In step 650b, standby mode is configured to receive the down link of cellular base stations.In step 650c, obtain the base station IDs in the control information 521 (Figure 18) in the down link signal, and/or it is stored in the memory 557 (Figure 21).In step 650d, check whether down link signal comprises the transmission information 528 (Figure 18) of the broadcasting such as TV and/or the data of the first transmission information 526, or the identifier of indicating above-mentioned two segment informations to exist.If the result is " affirming ", process forwards step 650e to, and if " negating ", process forwards step 650j to, three signs are set, and then, process forwards step 650k to.
Turn back to step 650d, if the result is " affirming ", process forwards step 650e to, obtains transmission information 528 and/or the first transmission information 526, and/or it is recorded in the memory 557.In step 650f, whether the inspection down link signal comprises the second transmission information 525 or indicates the identifier of its existence.If the result " negates ", in step 650i, sign " 2 " is set, then, process forwards step 650k to.If the result is " affirming ", in step 650g, from down link data, obtain the second transmission information, perhaps, the information recording/that obtains in memory 557.In step 650h, sign " 1 " is set.In step 650k, " begin to receive the broadcasting as TV " when receiving instruction, that is, during the T mode instruction, the transmission information parameter in once receiving before whether the judgement user utilizes and be used in step 650m receives signal.When the user does not have cuit, send information control section 556 (Figure 21) and just determine it.According to the data that send in the information database 559, if since utilizing time control, since the front once reception in broadcasting station, also do not pass through certain hour or longer time, perhaps, if base station IDs 521 (Figure 18) is identical with front when once receiving that, process is goed ahead along " affirming " branch, otherwise branch gos ahead along " negating ", forwards step 651a to.In the situation that " affirming ", process forwards step 650n to, utilizes the same channel with front transmission parameter to arrange and receives and attempt to receive.If receive successfully, process forwards the step 650p with " affirming " character to, begins to receive.If receive unsuccessfully, process forwards the step 651a among Figure 24 to.
When sign is " 1 " or " 2 " in step 651a, can determine at least to have obtained transmission information and the first transmission information, and, in step 651b, show the channel that can receive transmission information 528 at screen by the demonstration field intensity group as menu screen.If receiver is T pattern cellular phone, send identifier 550 according to the part in the first transmission information 526 among Figure 18, the signal that only can receive transmission information and the channel that carries out the part transmission is displayed on the display part 590 (Figure 21).In receiving Figure 17, during the data of programme information transmitting portion 562, show that simultaneously the programme information of different channels has the easier effect of the user selection of making program.When in step 651c, when the user receives the instruction of particular channel from inputs such as keyboards, process forwards step 651d to, if with flag=1 be " affirming ", forward step 651f to, and if " negating ", this means flag=2 and can not obtain the second transmission information, therefore, process forwards step 651e to.In step 651e, tuning and utilize transmission information and first to send the above-mentioned particular channel of demodulates information, obtain the ground floor data, obtain demodulating information wherein, obtain the second transmission information, and process forwards step 651f to.In step 651f, utilize transmission information and/or the first transmission information and/or second to send demodulates information ground floor, the second layer and all more high-rise data, after the processing in step 651g, 651f, 651w, 651y and 651z, process forwards the step 652a among Figure 25 to.Turn back to the step 651a among Figure 24, in the situation that " negating ", flag=" 3 " therefore, can judge that the base station can only obtain the information of base station IDs.In this case, in step 651h, check comprise the transmission information relevant with the current time zone of relevant base station IDs transmission information whether in sending information database 559 (Figure 21).If " affirming ", in step 651i, obtain the transmission information corresponding with base station IDs.When receiving the instruction that receives particular channel in step 651j, process forwards step 651k to, has a look at whether to have the second transmission information.If " affirming ", process forwards step 651f to, utilizes parametric demodulation ground floor, the second layer and more high-rise.If " negating ", process forwards step 651e to, reproduces the demodulating information of ground floor.To describe later on step subsequently, therefore, omit the explanation to it here.
Turn back to step 651h, if the result is " negating ", process forwards step 651m to, and, when waiting the instruction that receives the reception particular channel from the user, check that in step 651n cellular phone is in up link and sends prohibited mode, usual pattern is still under " T pattern " (dedicated broadcast receiving mode).If the result is " negating ", process forwards step 651p to, and, when receiving the instruction of obtaining receive data by phone transmission information control section 556 (Figure 21) from the user, that is to say, in the situation that " affirming ", process forwards step 651q to.Step 651q is by the honeycomb fashion electric wire, connect certain database (DB) or URL (URL(uniform resource locator)) server in up link, and, in step 651r, obtain or download broadcast reception transmission information and/or the programme information corresponding with relevant base station IDs, and in step 651s, record or renewal send acquisition transmission information and/or the programme information in the information database 559 in addition, then, process forwards step 651k to.
Turn back to step 651n, when the result is " negating ", that is to say, in the situation that up link sends prohibited mode, process forwards step 651t to, the frequency of tuning particular channel and search send the operating frequency control table 609 (Figure 22) in the information database 559, as the parameter of the first transmission information 526.Then, from correlated channels ID, select to contain the channel id of the high information of operating frequency, the parameter of different piece is set, and/or change and demodulation settings.Check in step 651u whether demodulation achieves success, and if " negating " in step 651t, becomes frequency the highest inferior parameter to parameter change, reattempt demodulation.In the situation that can demodulation, that is to say, if " affirming ", in step 651v, the demodulation ground floor obtains demodulating information, and process forwards step 651f to and recovers.
Among the step 651f in Figure 24, utilize the first transmission information and second to send demodulates information and receive signal, in step 651g, output and demonstration receive data, and, when in step 651w, be sure of that this output and demonstration have continued certain hour, that is to say, only in the situation that " affirming ", in step 651y, upgrade the frequency information that first and second of channel id sends information along increasing progressively direction.In step 651z, utilize the nearest transmission parameter value of respective channel ID to upgrade the data of the nearest parameter of nearest working time control table 613.Shown in the arrow among the figure, previous nearest parameter 615 moves to time recently parameter 615, and previous time recently in the near section of the data mobile to the in the section of parameter 615 three.If the 3rd nearly parameter is nearest, it just is moved upwards up to nearest parameter 614.Therefore, if the nearest operating time is set, namely, the parameter priority mode so, is used nearest parameter among the step 650m in Figure 23 recently, therefore, in the situation in the season that is suitable for receiving from the broadcasting station of the parameter of only using AD HOC, or send parameter in the situation that change every year, this time control model is suitable for.For each broadcasting station setup times control model and FREQUENCY CONTROL pattern more effective.Then, along with cellular phone is moved, process forwards the step 652a among Figure 25 to.
(5-5-2) switching of broadcast channel
Utilize now Figure 25 that movement according to cellular phone, the method for switching between broadcast channel are described.
Change because move with cellular phone the base station, in step 652a, change base station IDs.Utilization is at the field intensity control program shown in the step 652b, and the present invention is received the broadcast channel with best field intensity.Used in this manual the example of TV platform, still, in fact, comprised TV broadcasting, music broadcast and data broadcast, the present invention can be applicable to any of these broadcasting situations.In step 652b, shown the method for from the position of the positional information of the transmitting antenna of each TV platform and base station, calculating the distance between these two radio station.Cellular phone comprises position detection part 558 as shown in figure 21.The W-CDMA system especially can receive and power ratio control simultaneously from three base stations, so that the recipient can receive the signal with best power, therefore, power control information 611 shown in Figure 180 is so that can by the calculating such as triangulation technique, find out the relative position of cellular phone and base station.In case the position relationship between base station and each broadcast antenna is known, so, can accurately know the distance between each broadcast antenna and the cellular phone.In the situation that can accept approximate distance, can use the distance between base station and the broadcast antenna.Field intensity 535 among Figure 18 comprises that each broadcasting station is in the field intensity of base station.In the situation that can accept approximate distance, can use this field intensity data.
In the 2nd of step 652b, along with base station IDs changes, the field intensity control section 612 among Figure 21 relatively moves the data of the field intensity 535 in each broadcasting station, front and back by computing, thereby, the broadcasting station is divided into three groups; One group of its field intensity moves with cellular phone and the enhanced intensity broadcasting station that strengthens, one group of its field intensity moves with cellular phone and the field intensity that weakens weakens broadcasting station and one group of broadcasting station that its field intensity remains unchanged.
In next step 652c, if the field intensity in current reception broadcasting station drops to the first fixed value following (in the situation that " affirming "), process forwards step 652d to, and in the situation that " negating ", process turns back to step 652a.When in step 652d, the current broadcast radio station does not belong to field intensity when weakening broadcasting station group (" negating "), process turns back to step 652b, with in the situation that " affirming ", in step 652e, check the same services ID that whether exists as the identifier of the programme content of indicating the current broadcast radio station, namely, another new broadcasting station with identical content, if " negating ", process forwards step 652I to, and if " affirming ", when in next step 652f, when the field intensity in new broadcasting station was equal to or greater than second value (affirming), process jumped to step 652h.If " negating ", when in next step 652g, when the field intensity in new broadcasting station is better than the field intensity in current broadcast radio station and does not belong to enhanced intensity broadcasting station group (" negating "), process jumps to step 652I, with if " affirming ", in next step 652h, beginning has channel switch in the middle of the new broadcasting station with same services ID the channel in the new broadcasting station of high field intensity, then, process forwards the step 653a among step Figure 26 to.
Refer to as the step 652I of several step redirects destination that presence service ID is not identical with the current broadcast radio station, that is, have the new broadcasting station of same program content.Therefore, the channel that receiving of user need to change over the different one other channel of service content.In step 652i, display message " can change channel? ", with when in step 652j, during user input instruction " OK ", perhaps, when default settings " OK ", process forwards step 652k to.In step 652k, begin to select new broadcasting station, check in step 652m whether field intensity is equal to or greater than certain value.If " negating ", process turns back to step 652k, and if " affirm ", check in step 652n whether the broadcasting station belongs to field intensity and weaken the broadcasting station group, if " affirming ", process turns back to step 652k, with if " negating ", process forwards step 652p to.
In step 652p, the frequency information of the channel id in relevant new broadcasting station in the search work FREQUENCY CONTROL table 609 (Figure 22) is to find out the new broadcasting station with high frequency of utilization.In the situation that " negating ", repeating step 652k is to 652p, and if find broadcasting station (" affirming "), process forwards step 652q to, receives the highest new broadcasting station of frequency of utilization, then, process forwards the step 653a among step Figure 26 to.Even cellular phone is moved, field intensity control program of the present invention also can be selected the strongest channel of field intensity, therefore, always can receive broadcast service under the optimum reception condition.
(5-5-3) seamless channel switches
Figure 26 shown by the broadcast reception signal, or switches at two interchannels from server or base station by the honeycomb fashion channel, obtains the flow chart of ad hoc approach of the transmission information in new broadcasting station.In step 653a, not only from the base station, and from the broadcast reception signal, obtain the first or second transmission information in new broadcasting station.At first, check in step 653b whether flag=1 sets up.If " affirming ", from the base station, obtain all transmission information, therefore, process forwards step 653j to.If " negating ", process forwards step 653c to, and whether the broadcast singal that checks current reception in step 653c comprises the base station IDs corresponding with area code or new broadcast channel, other channel sends information 528 (Figure 18), the first or second transmission information 526 or 525.If " affirming "; process forwards step 653d to; obtain transmission information and when being necessary; it is recorded among the transmission information D B; then, process forwards step 653j to, utilizes the first or second transmission information in new broadcasting station; protecting interim, switch to new channel from current channel.In this case, because transmission information and the first or second transmission information were known, omit the step of demodulation ground floor before demodulation, protected interim to finish soon switching.This has in the situation that do not interrupt data receiver, that is, and and the outstanding effect of switching channels seamlessly.In step 653k, send the new channel of demodulates information according to first or second, and in step 653m, export and/or show new channel data, and, check in step 653n whether the new channel of output reaches certain hour or longer.If " negating " continue to check, and if " affirm ", in step 653p, increase by frequency of utilization information and renewal operating frequency table 609 that the first transmission information and second relevant with channel id with new channel sends information.Simultaneously, upgrade the nearest temporal information of nearest working time control table 613 (Figure 22).
Turn back to step 653c (Figure 26), if the result negates that in step 653f, whether display part inquiry user obtains transmission information by the honeycomb fashion channel.If " affirming ", in step 653g, send address or the URL of information source in up link.Then, in step 653h, send base station IDs and required channel, in step 653i, receive the first and second transmission information and it is recorded in and send among the information D B.Then, process forwards step 653j to and carries out along identical step.
On the other hand, if the result in step 653f is " negating ", switching channels in step 653q, and, if there is no send information, search for transmitting channel and channel switch is arrived other channel.If in step 653f, also do not find the first transmission information, in step 653r, search for the first transmission information by repetition test, the demodulation ground floor, with the acquisition demodulating information, and, the demodulation second layer, if the result of step 653s is " OK ", process forwards above-mentioned steps 653m to.If " negating ", repeating step 653r.
Follow said process, even therefrom the home base stations of receive data is not supported the present invention and the base station IDs that just can receive, but, because the broadcast reception signal in each radio station comprises transmission information, first and second transmission information corresponding with the base station IDs in other radio station, the present invention has the seamless effect that switches to another broadcasting station from a broadcasting station.In addition, even without finding above-mentioned service, also can obtain from server by the honeycomb fashion channel, this is so that can obtain in any environment transmission information and seamlessly switch at interchannel.
(5-5-4) at the base station Notification Office in the situation of the broadcast channel number among the service,
Figure 27 has described the channel that utilizes the broadcasting station common, for different broadcasting stations provide the process of realm identifier ID and the effect that reaches.In step 654a, the base station sends channel number and broadcasting station realm identifier ID or the broadcasting station special I D in broadcasting station.In step 654b, cellular phone receives this information, and, in step 654c, check whether broadcasting station special I D of ID.If " affirming ", process forwards step 654d to, waits for the instruction of receive channel (n).When instruction arrives, in step 654e, utilize to send the transmission information whether information D B inspection exists the broadcasting station, and if there is the broadcasting station, process forwards the step 655a among Figure 28 to.If " negating ", process turns back to step 654d, because in fact it is not special I D, tuning or utilization contains the highest this information of transmission demodulates information transmission information, channel id of operating frequency.
(5-5-5) renewal frequency control table
Figure 28 has described when being equipped with FREQUENCY CONTROL table 609 (Figure 22) for each channel id, the method for the priority of control frequency and renewal frequency information or frequency control data.
Whether step 655a judgement can utilize the first transmission information to receive the ground floor of Ch (n).If " negating ", process forwards step 655t to, and n=0 is set, and in next step 655u, n=n+1 is set, and the parameter whether judgement can utilize the first transmission information to have priority n is carried out demodulation (step 656a).If " affirming ", process forwards step 656b to, checks to receive whether continued certain hour or longer.If " affirming ", increase the frequency information (step 656c) that first of this n parameter or the first sending mode sends information.When the result of step 656b be " negating " the time, skips steps 656c.When in step 656d, (n-1) frequency information switches n and (n-1) priority during less than this n frequency information (affirming) back and forth in step 656e.Then, process forwards step 655b to.Here, turn back to step 656a, if the result is " negating ", process forwards step 656g to, by changing the parameter of the first transmission information, attempt demodulation, until n becomes greater than n (LAST), and, if " affirming ", process forwards above-mentioned steps 656b to.But, when n becomes greater than n (LAST), in step 656h, change the first parameter that sends information, until can demodulation it.When obtaining separating, the first parameter that sends information is in harmonious proportion in step 656i, reception has continued certain hour or when longer, if with in step 656j, n (LAST) frequency information is equal to or less than certain value, in step 656k, this transmission information is sent the control table of information data renewal frequency as n (LAST) first.Perhaps, this transmission information is upgraded the FREQUENCY CONTROL table that comprises other data as the nearest data 614 of nearest working time control table 613.Then, process forwards above-mentioned steps 656d to.
On the other hand, turn back to step 655a, if the result is " affirming ", process forwards step 655b to, and n=0 is set, in next step 655d, n+1 is used as n, in step 655e, utilize the operating frequency control table 609 among Figure 22, or n operating frequency or the high precedence information of nearest operating frequency of working time control table 613 are attempted demodulation recently.In the situation of demodulation, that is to say, in the situation that " affirming ", in step 655f, check to receive and whether continued certain hour or longer, if with the result in step 655f be " affirming ", in step 655g, increase the n frequency information that second of operating frequency control table 609 sends information, perhaps, the second n frequency information that sends information of nearest working time control table 613 is recorded in the section of nearest class 6 14, and, the grade in the new rank of other parameter is added 1.If in step 655h, the n frequency information is higher than (n-1) frequency information, in step 655i, switch back and forth this order of two.Then, in step 655k, receiving broadcast signal.
Here, turn back to step 655e, when the result was " negating ", if in step 655m, n did not surpass end value, and process turns back to above-mentioned steps 655d.If n surpasses end value, demodulation ground floor in step 655n, obtaining the transmission information in the demodulating information, and the demodulation second layer.When in step 566p, receive and to have continued certain hour or when longer, and in step 655q, in the situation that nearest time control model, this reference record in nearest class 6 14, to reduce other new rank.In the situation that FREQUENCY CONTROL, when the last frequency information of n is equal to or less than certain value, in step 655r, substitute this parameter with the final parameter of n, upgrade and record this parameter.When the last frequency information of n is not less than certain value, receiving broadcast signal in step 655k.As implied above, owing to can the transmission information to each broadcasting station carry out FREQUENCY CONTROL under the FREQUENCY CONTROL pattern, when having the transmission parameter in many kinds of broadcasting stations, this pattern is effective.And for the broadcasting station that changes transmission information in the long period such as annual or per season, the working time control pattern is effective recently.When existing a few to send parameter, the working time control pattern also is effective recently.Said method has produced the effect that improves the hit rate of transmission information.
Figure 29 shown and front a kind of identical method, by means of this method, in step 657i, with broadcasting station ID and base station IDs interrelates and will be registered in during transmission information controls database.Then, in step 657j, changed into such as shown in figure 22 send parameter mode, have the AD HOC such as first mode number the 554 and second mode number 555, and, in step 557k, register them, thereby, the effect of remarkable minimizing registration data amount produced.
(6) the 6th embodiment
The embodiment of the new business prototype of utilizing cellular phone 501 will be described now.Figure 30 is the business procedure figure of this business prototype.
(6-1) cellular phone
At first, the cellular phone of using in this embodiment is described.Figure 31 is that secondary display part 592 is contained in front view and the display part 590 of cellular phone 501.Figure 31 (a) has shown the display part 590 of display menu screen, and Figure 31 (b) has shown the display part 590 under bar code display pattern or the BC pattern.Under the BC pattern, secondary display part 592 show bar shape codes.
Figure 32 has shown when display part 590 is furnished with colour display functions, the layout of the image 701 of display unit of the present invention.Shown in Figure 32 (b), 702 the top in the boundary line is being arranged in order the color filter plate with three kinds of colors of RGB along horizontal direction.Therefore, express in the horizontal direction a pixel and need three unit 700.If supposing " L " is the distance between the adjacent cells, so, a pixel has the spacing of 3L.The code-bar 703 of attempting to utilize traditional color display unit to utilize bar code causes 3L or larger spacing as code-bar 703,703a and 703b, fails to demonstrate code-bar 704,704a, 704b and the 704c of the slice shape code shown in Figure 32 (d).
Specifically, as shown in figure 34, bar code reader 708 general using red lasers or red beam are as the light source 709 of luminous component 710, therefore, light beam passes the R filter 705 shown in the profile of Figure 33 (a), and by the shorter G filter 706 of wavelength and the filter action of B filter 707, the light quantity of passing significantly reduces.For this reason, can stably read in order to make the bar code reader that contains red light source, should be widened to 3L or larger to the spacing of code-bar.Especially in the situation of the little cellular phone in display part, attempt the show bar shape code and reduced significantly amount of information.
The present invention is shown thin code-bar 704 by be equipped with secondary display part 592 in that part of display part 590.Shown in Figure 32 (c), the colour filter flaggy under boundary line 702 forms by making bar code obtain the monochromatic transparent filter that shows.The colour filter flaggy has the spacing of 100 μ m along vertical direction, and utilizes present technique, can be the magnitude of 30 μ m along the pel spacing of horizontal direction.Therefore, owing to can show as shown in Figure 32 (d) that spacing is the slice shape code of 30 μ m, even little display part also can show the bar code of large data.
The cutaway view of Figure 33 (a) and (b) shown that respectively A-A ' part and B-B ' part in Figure 32 cut the structure of the present invention that obtains.Colored display part 724 among Figure 33 (a) begins to comprise reflector 713, polarising sheet 714 and substrate of glass 715 from the bottom.Form transistor 716 and electrode 717 in substrate of glass 715, form color filter plate 720 and ITO719 in the inside of upper glass plates 721, and begin polarising sheet 722 in the outside of upper glass plates 721.
Between upper glass plates 721 and lower glass plate 715, inject liquid crystal material.Incident light 711a, the 711b that comes from the outside and 771c through liquid crystal 718, are reflected body 713 reflections by polarising sheet 722 polarization, again pass through liquid crystal 718, through polarising sheet 722, become reverberation 712a, 712b and 712c.The polarizing angle of reverberation 712 and intensity are controlled by the voltage that change is applied on the liquid crystal.
At this moment, in the situation that incident light is white light, color filter plate part 720 absorbs white light, thereby generates the reverberation of RGB.But when as bar code reader 708, when light source had ruddiness, R filter 705 did not absorb, reflection ray.But the absorption of G filter 706 increases, and B filter 707 has almost absorbed all light.Therefore, attempting the show bar shape code can make B filter 707 and G filter 706 are identified as mistakenly code-bar.
The present invention has used the substrate of glass 715 that is made of a display unit, and has constructed shown in Figure 33 (b), with the secondary display part 592 of the hyaline layer 723 that does not contain colour filter flaggy 720.For this reason, when incident light 711 is ruddiness, stand identical decay through the reverberation 713 of any pixel cell 700, therefore, show that bar code on the secondary display part 592 can not make in addition highdensity code-bar by wrong identification.This has just produced the effect that shows jumbo bar code.
In this case, shown in figure 32, the present invention has used unit 700 and the secondary display part 592 that has same widths with the colored display part as main display part.Shown in the unit 700 of Figure 32, by at least the breadth length ratio of monochrome cells being arranged to 1:2 or larger, identical display unit can be shared with secondary display part in colored display part.Owing to only for the zone of secondary display part, must only replace color filter plate with transparent material, therefore, only needing to add a procedure.If hyaline layer 723 forms by thickening ITO layer 719, so, need not to increase operation and just can make, this is convenient to batch production.
Display unit of the present invention is used for needs 3 or 4 bar codes that will show such as electronic clearing system.Attempt show bar shape code 3 or occasion a great deal of trouble for 4 times, and, the processing time increased.
For this is improved, display device of the present invention has been equipped with as shown in figure 31, and near the optical detection part secondary display part 592 divides 725, to detect the light from bar code reader.For the light source 709 of the luminous component 710 of bar code reader 708, normal operation ruddiness.As shown in figure 35, this light divides 725 to detect by optical detection part.In order to distinguish stray light and to read light, optical detection part divides 725 light input window 727 to be furnished with the color filter plate 726 that only allows ruddiness to pass through.This color filter plate can reduce the optical noise that becomes interference.The signal that detects is measured by luminous intensity measurement part 728 and light measure portion input time 729, introduced in continuous signal test section 731 and the pulse signal detection part 732 by separating part 731, by bar code display control section 733 its display update is become new bar code, and upgrade the bar code display of secondary display part 592 by display circuit 734.
This process will utilize the flow chart among Figure 36 to be illustrated.Bar code display in step 661b, arranges n=0 from step 661a, in step 661c, add n=1, and in step 661d, show the n bar code.When in step 661e, when optical detection part divides 725 to detect the light that bar code reader reads, whether judgement exists light quantity to be equal to or greater than the incident light of certain value I1 at certain hour t1 or in the longer time in step 661f, in order to check, whether look at the light from continuous radiation type bar code reader.If be " affirming " here, judgement is the light from bar code reader, and, judgement n end value whether in step 661h.If " affirming ", process finishes, and if " negating ", process turns back to step 661c, and n is added 1, and, at secondary display part 592 (Figure 35) demonstration n bar code, that is, and next bar code.
Turn back to step 661f, if the result is " negating ", in step 661g, check the radiation that whether has any sweep type bar code reader.Have short pulse signal that particular light I2 reaches certain hour t2 (t1〉t2) and reach certain frequency n 1 or more times detecting, with (t2＜t3), judgement sweep type bar code reader has been read in the situation that passed through certain hour t3 among the step 661j.In step 661n, if n is end value, in step 661i, process finishes.If not end value, in step 661c, n is added 1.Therefore, bar code reader t1 in second radiation read light, automatic display of new bar code one by one, therefore, the user need not to carry out any operation and upgrades bar code.
(6-2) explanation of total business prototype
Figure 30 has shown by checking and has bought, and accepts product, and utilizes the business procedure figure of the business prototype that T pattern cellular phone 501 pays.At first, in step 660a, broadcasting station 502 utilizes radio wave that product purchase process software and product data are sent to cellular phone 501, the product purchase process software is to use the World Wide Web (WWW) descriptive language, for example, be used for PC (personal computer) HTML (HTML), be used for the BML (broadcast markup language) of broadcasting or be used for the program that the JAVA of mobile device is write as.
The user utilizes the product purchase process software to set up a web site and open the homepage of buying product at server.In step 660b, user selection virtual shop 740, and utilize the up link 507 of cellular phone, by cellular phone corporate server 742, internet 741, Control on Communication part 743 and virtual shop's server 744, accesses virtual shop 740.
In step 660c, cellular base stations 503 utilizes down link 506 to send product information and standard price information.In step 660d, user selection product, service and ticket, and utilize up link 570 that ordering information is sent to virtual shop 740.In step 660e, the information of relevant method of payment, price, discount rebate coupon etc. is sent to the user.
In step 660f, the user selects method of payment in the shop that the discount rebate coupon is arranged, namely, verify, pay or settle accounts and accept the method for product in the actual store such as cheap shop, and, utilize up link, information, and user's cellular phone number sends to the virtual shop.
In step 660g, virtual shop 740 checks the price rebate rebate coupon, then, the arithmetical discount price, the number of registration that encryption interrelates product information and discounted cost and user's cellular phone number, further encrypt it, and utilize down link 506 or send it to the user by Email.In step 660h, the number of registration of order has been registered in the number of registration memory 747 registration indications of cellular phone 501 with the n number of registration.
When the finishing dealing with of system, in step 660i, user 746 is carrying cellular phone, goes to the actual store 748 of user's appointment such as cheap shop.In step 660j, the user switches to the BC pattern to pattern, prepares on secondary display part 592, utilizes bar code to show one by one m the data such as n number of registration, product IDs, discounted cost m time, and, at first show first bar code.
In step 660k, the employee of actual store 748 utilizes the bar code of bar code reader 708 reading displayed on the secondary display part 592 of display part 590 that is connected with POS (point of sale) terminal 750.
Respond to reading light, cellular phone 501 is according to the detection signal of test section 725, changes and show bar shape code m time.Perhaps, such as Figure 43 or shown in Figure 44, cellular phone 501 shows m bar code one by one in certain intervals.In step 660m, when bar code reader 708 had been read the m bar code, bar code reader 708 sent to virtual shop 740 to data by clearing houses 900.
In step 660n, the virtual shop checks number of registration, honeycomb fashion ID, product IDs, discounted cost etc., and, if " OK ", so, in step 660p, by clearing houses 900 information such as discounted cost, product IDs etc. is sent to POS terminal 750.In step 660q, POS terminal 750 is utilized credit card etc., balance an account by discounted cost, and, in case finish clearing, just product is consigned to the user.
(6-3) system detail
The below will utilize Figure 37 to illustrate in greater detail Figure 30.Purchase order is sent to server 801 from the cellular phone 501 that comprises client computer 800.Passing through the cellular phone line, after client computer 800 receives cellular phone number 804 bridge media that is recorded in such as SIM (SIM system information management) card 803, user ID 805, payment information, shipment information, positional information 816, server 801 is specified an assigned I D, to control this event.
Simultaneously, the inventory database 815 in the shop 748 of the contiguous store information 819 of server by utilizing checks the product inventory situation, and selects in stock shop.In addition, server by utilizing temporal information 817 is provided rebate coupon ID, and, it is registered in rebate coupon controls database in 820.When the user selects specific actual store 748 from contiguous store information 819, select the order button of specific products, and during input message, by cellular phone this information is sent to server 801.
In case receive the purchase request of specific products, server 801 just utilizes assigned I D806, with relative clients database 812, inventory database 810, order database 811 with utilize client computer ID814 such as the cellular phone number 804 of client computer 800 and/or purchase information and the client computer ID client table 809 of user ID 805 combined.Then, server sends selected product, the information relevant with assigned I D806, utilizes discount rate according to rebate coupon control database 820 product values 823 that calculate, the information about the rebate coupon deadline, purchase deadline, product IDs 824 and rebate coupon discount rate 825, so that actual store 748 is stored in information in the purchase database 822 of POS terminal 750 to the actual store 748 of user selection.
When the consumer accesses actual store 748, when selecting the product that will buy and pressing the BC mode switch with cellular phone 501, circulation bar code of the present invention is displayed on the display part 590, is read by bar code reader 708, and, read at least assigned I D806.Extract the amount of money 823 and the rebate coupon discount rate 822 of product in the purchase database 822 from memory, calculate purchasing price, it is presented on the POS terminal 750, and, according to the clearing delivered product.When utilizing credit card to settle accounts, settle accounts by communication.
This system allows to need not to use telecommunication circuit when buying, just can check, thereby, can verify at once and accelerate to process.This system is for the clearing in cheap shop, or people to arrange the booking of team in the theater porch be effective.If utilize cellular phone etc. to finish in advance settlement process, so, this system takes time hardly, thereby, can manage many users.
(6-4) actual ecommerce
The example of the actual commercial affairs that utilize above-mentioned business prototype then, is described.As the example of this product, suppose to require to make a reservation in advance.According to current airplane ticket reservation system, the user subscribes by phone or personal computer, receives number of registration, and the visit information platform is oral or tell the employee number of registration with a piece of paper.The employee manually inputs number of registration, and the center checks it, then, and user-pay and reception air ticket.By means of the present invention, the user can utilize cellular phone 501, can buy reservation anywhere, and, need not oral notification data and be up at a piece of paper, can be on the display part 590 of cellular phone 501 go out checking number and number of registration by bar code display.
The present invention makes the user can utilize the process identical with the sort of process that illustrates in Figure 30, obtains ticket by cellular phone.At first, the user accesses the n virtual shop 740 of sell tickets or concert admission ticket, and selects the product (step 660b) such as air ticket or admission ticket.User's handle relevant with air ticket, require the information of exact date, concrete time, specific purposes ground, the attribute information such as the close seat of passage to send to virtual shop 740.In the situation of admission ticket, the user sends the information about concrete concert, exact date, concrete time or concrete time and concrete seat and the expectation admission fee in concrete scope.
In step 660c, virtual shop 704 sends product information.In the situation of air ticket, the order that virtual shop 740 increases progressively with admission fee sends relevant to the expectation date/time, go to the expectation destination, the information of the air ticket of the flight of empty seats also, and, shown in Figure 31 (C), finally information is presented on the display part 590 of cellular phone 501.
That is to say, the 1st row of tabulation has shown flight number, the departure time or specified time of arrival, the sum of expectation vacant place, for example, lowest fare is that 99 dollars flight also has 25 seats, perhaps, the seat number at demonstration and user's the immediate seat of preference, for example, " 14B ".The capable air ticket that shows that n is cheap of n.In the situation of the admission ticket of film, concert and amusement park etc., the order that this tabulation increases progressively with admission fee or distance or show the performance of identical content or attract thing with the order of preference.
In the situation of amusement park, after having bought admission ticket, the right that can subscribe different facilities or obtain to subscribe different facilities.In this case, shown in Figure 38 and Figure 31 (E), cellular phone 501 at first receives the relevant information that attracts the free space situation in thing or restaurant from the center, set up the tabulation that attracts thing or restaurant can subscribe the order that entry time increases progressively, and tabulation is presented on the display part 590.
When using the cellular phone line, the user sends to center and the information that receives relevant free space situation from the center to request, in the situation of unidirectional data broadcast, information or the reservation state information data many times that repeat relevant free space situation are broadcasted in the mode of circulation in the center.The user selects from loop-around data, obtains and show the information of the attraction thing that he/her selects.
Figure 31 (E) has shown concrete demonstration.This tabulation has shown " cable car ",, attracts that name claims, " 11:30 " that is, that is, ticket reserving time, " 14 " number, that is, all the other numbers that can subscribe, " A " district namely, attract the position of thing in the amusement park.The order that shows in the tabulation is corresponding to the incremental order of entry time, perhaps, be equivalent in the amusement park to attract the gps system of above-mentioned position, user's cellular phone 501 of thing, from the positional information such as base station IDs of base station or from the positional information 816 of the position detection part 558 (Figure 37) such as direction sensor etc.Like this, attraction thing or performance near the cellular phone search cellular phone 501, the order that increases progressively with distance shows, thereby, make the user can easily choose nearer attraction thing.In the situation at the restaurant, cellular phone is set up tabulation with the order of price increases, and shows this tabulation.If the time quite early, so, show the discounted cost in the certain hour interval.
Shown this process among the step 827a of the flow chart in Figure 38 and the 827b.In step 827c, cellular phone 501 obtains the same day about attracting the information in thing and restaurant at the homepage of the virtual shop of access amusement park, internet.The user selects the concrete thing that attracts in the middle of them, in step 827d, input with the reservation tupe, with ID number of the admission ticket 832 (Figure 30) that the user is had, or the password that writes on when being necessary in the admission ticket 832 is manually inputted in the cellular phone 501 (step 827e).When member of family etc. needs more admission ticket, input several ID and password.
In step 827f, cellular phone is these admission tickets ID, cellular phone ID and attract thing ID to send to the center.Whether in the situation that attracts thing to subscribe, the center utilizes timer, effective according to the reservation admission ticket that this admission ticket inspection was provided in the past.In this case, because certain situation if the right of the specific admission ticket ID of current use is invalid, so, arranges the sign that indication bans use of specific admission ticket ID in central database, therefore, (step 827g) forbidden in the use of admission ticket.If the right to use is still effective, so, the center is provided and is subscribed admission ticket or interim admission ticket.
At this time point, because admission ticket away from ticket machine, can not be provided in the center.Therefore, checking number is provided at the center, that is, interim admission ticket information is encrypted it and it is sent to cellular phone 501.Cellular phone 501 is preserved this information in the memory 802 (Figure 37) (step 827k).More particularly, the title of memory stores reservation attraction thing, time started, position, authorization information etc.According to above-mentioned time started information, cellular phone 501 certain hour before the time started drives loud speaker or the oscillating component of cellular phone 501, with this part thing of reminding user, and, urge the user to go to that place.
Then, the user goes to from the place of entrance at the equipment of entering 828 or the ticket machine 829 that attract the thing porch.Cellular phone 501 inputs are subscribed and are provided or allow the admission tupe.If passed through certain hour or longer, perhaps, this time has exceeded the scope of subscribing the stipulated time, and therefore the setup and use prohibitory sign, can not accept the process (step 827j) among step 827k and the 827p.
In step 827m, whether the device id of inspection such as the telephone number of cellular phone 501 contrasts admission ticket ID is registered in the central database, and if be registered, process jumps to step 827q.If be registered, omit the checking inspection to portable terminal, it is unique that what will do is in the admission ticket inserted with card reader 831.
If also be not registered, portable terminal utilizes bar code etc. to show checking number.If the amount of information that shows is very large, use bluetooth (Bluetooth) and bar code display, replace verifying number.Shown in Figure 31 (b), communication mutually token or the id information of checking have been shown in the display part 590 of cellular phone 501.Bar code reader 708 (Figure 37) reads this bar code, to obtain mutual checking, communication token or id information.In the situation that one-dimensional bar code uses the bar code reader with the one dimension transducer, and in the situation that two-dimensional bar uses the bar code reader with the dimension sensor such as video camera.
Then, cellular phone 501 passes through bluetooth, sending/receiving to/from the information of ticket machine 829 (Figure 30) etc., thereby, can between specific POS terminal 750 and particular cell phone 501, set up reliable communication and prevent misoperation or swindle (step 827n).
In the porch, people are arranging team, in the area of communications services such as bluetooth and radio LAN (local area network (LAN)) some portable terminals are arranged, therefore, be difficult to recognition machine with which terminal communication.The present invention reads in the mutual messaging parameter such as the bar code token on the display part of the portable terminal in porch, and, utilize those parameters to communicate.So just can identify a communication counterpart, significantly improve confidentiality and prevented misoperation.
Shown in 592a (Figure 31), except the token that utilizes the large two-dimensional bar of the capacity of display, also send the large capacity encryption key that is used for coded communication, and, utilize this encryption key that allows high secure communication, mutually carry out radio communication.Here the example of having showed bluetooth still, utilizes radio LAN IEEE802.11a.11b also can obtain similar effect.
Then, in step 827p, bar code reader 708 reads checking number, and in Figure 30, when whether correct the center of virtual shop's 740 indications check and the result of calculation of judgement checking number when, process forwards the permission pattern among the step 827r to.In the situation of the pattern that enters in step 827t, open and enter 830 among Figure 30, make the user enter the place (step 827u) that attracts thing, concert or performance.After having appreciated the attraction thing, the next thing that attracts of request is tabulated in the step 827a on top.
Turn back to step 827r, in the situation that subscribe the ticketing pattern, in step 827s, ticket machine 829 is provided and is subscribed admission ticket, the user can receive actual reservation admission ticket 832, and, when the ticket reserving time then, the user can pass and enter by subscribing in the admission ticket inserted with card reader 831.At this moment, attract the mark of thing to be arranged to " opening (ON) " being prohibited from entering, the user can not illegally be entered for the second time.Then, in step 827r, the center stops to provide any new checking number or the reservation admission ticket relevant with original admission ticket ID in a certain time interval, to prevent that in the same period providing two or more subscribes admission tickets.Above-mentioned reservation also can be set use prohibitory sign.
In the situation of amusement park, when the someone withdrawed from and reenter, for the people who verifies that this once withdrawed from, system utilized these people of checking such as UV ink.But, utilize bar code display of the present invention to make checking become possibility.When entering, the prohibitory sign that enters of admission ticket ID is arranged to " opening ".In the situation of user with portable terminal of of short duration appearance, from admission ticket, read admission ticket ID, utilize bar code display portable terminal ID, bar code reader reads bar code, and is arranged to " closing " entering prohibitory sign.When reentering, read equally admission ticket ID and portable terminal ID, and, check to enter prohibitory sign.
In the situation that legal use, admission ticket ID and portable terminal ID are complementary, and to enter prohibitory sign be " closing ", therefore, allow to reenter and the equipment 823 of entering is opened door.After entering, be arranged to " opening " and prevented from illegally entering entering prohibitory sign.In this case, the bar code display of portable terminal can be realized the virtual electronic admission ticket alone, need not to use admission ticket in kind.
The above-mentioned system that enters makes the user buy the electronics admission ticket by WEB in advance, obtains checking ID, and it is stored in the memory, verifies ID with bar code display, and is arranged to " opening " entering prohibitory sign.When withdrawing from, system reads the checking ID of portable terminal, is arranged to " closing " entering prohibitory sign, and when reentering, reads checking ID and be arranged to " opening " entering prohibitory sign, like this, has prevented any swindle.
Said method makes the user can obtain to obtain subscribing the right of admission ticket anywhere.Therefore, this has makes the user need not to access the place that attracts thing, just can obtain to obtain to subscribe the effect of the right of admission ticket.In step 827e, in case registered admission ticket ID and password, just they can be registered in the memory 802 of portable terminal 501 (Figure 34), therefore, need not for the second time input.In addition, in case in step 827n and 827p, carried out the checking of portable terminal, or utilize fixed terminal to verify, after this only utilize admission ticket ID just can verify.Consequently, when entering for the second time for another attracts thing, there is no need on the same day, again read bar code in the porch, this has by utilizing portable terminal only to subscribe and allow entrance machine or reservation ticket machine read admission ticket, the effect that just can make the user can obtain admission ticket or subscribe admission ticket.
Above-mentioned example is the situation of amusement park and performance, but, subscribe by utilizing portable terminal, allow the gate on airport read bar code and to obtain seat ticket, or allow machine read bar code and allow the user directly board by the gate, identical process also can be applicable to the situation of air ticket.
(6-5) the bar code display method 1
Then, the object lesson that shows the method that is used in the bar code in the ecommerce according to the present invention is described.Figure 31 (b) utilizes two types bar code, that is, two-dimensional bar 592a and one-dimensional bar code 592 are expressed identical data.At first, when data hour, two-dimensional bar 592a and one-dimensional bar code 592 do not change their display mode.
Then, when data were relatively large, two-dimensional bar 592a did not change its display mode, and one-dimensional bar code 592 is take timesharing as the basis, several display modes that the circulation display data content is different, thereby, show the large data indirectly be equivalent to two-dimensional bar.
When data were very large, two-dimensional bar 592a changed its display mode, but so not frequent, and one-dimensional bar code 592 is take timesharing as the basis, and circulation shows several display modes continually.Even show that data volume increases in the situation that encryption causes, this also makes bar code be shown fast.
This makes one-dimensional bar code and two-dimensional bar, and the two can show identical data simultaneously.This data or utilization dimension sensor such as video camera that also makes bar code reader 708 (Figure 30) can utilize the one dimension transducer to read and contain one-dimensional bar code reads the data that contain two-dimensional bar, thereby, compatibility is provided.This has the effect that the bar code reader that makes any type can reading out data.In addition, by showing one-dimensional bar code or two-dimensional bar, has the effect that shows larger data.Above-mentioned example is to show simultaneously one-dimensional bar code and two-dimensional bar situation for several times, still, shows respectively the similar effects that one-dimensional bar code or two-dimensional bar number of times also have increases the data volume that shows.
In the situation of low price product, can only verify number of registration, therefore, use for great majority, only show once just enough.Even data volume is large and bar code need to be shown for several times, the present invention is several bar codes of automatic Display one by one also, just can allow checking obtain fast processing at bar code reader 708 with the display part 590 that makes the user only hold cellular phone 501, therefore, produced and save proof procedure and compare the effect that has improved convenience with legacy system.
The cellular phone that contains the monochromatic display part 590 that shows of band can be at the highly dense bar code of any position display of screen, as long as it is 50 μ m or less along the spacing of horizontal direction.Shown in Figure 32 (c), aspect ratio is arranged to 2:1 or is not only made character greatlyr, and several highly dense bar codes 715,751a, 751b and 751c are shown as shown in Figure 39.Like this, need not to change screen, just can show in the shop checking number, product IDs and discounted cost etc.Therefore, utilize disposable demonstration just to finish all processing.
(6-6) utilize the electronically validating of down link
Again according to Figure 30, shown in the situation that in not transmission of up link, the electronically validating method of only utilizing down link to process namely, is only applicable to broadcast the electronically validating method of T pattern in the bottom of figure.
At first, the step 660a of broadcasting station 502 transmission product purchase softwares and product data and downloading data is identical.In step 662a, the user 746 of cellular phone 501 selects virtual shop 740.In step 662b, utilize the product purchase software of particular business and the information that product data show related products or service price.In step 662c, select in the middle of the product that shows, to select specific products.In step 662d, product purchase software shows the amount of money and clearing form.In step 662e, be accompanied by the rebate coupon information of some benefits that comprise discount and so on such as fruit product, so, in step 662f, show discounted cost.
When user 746 selects to buy product and also has available rebate coupon in step 662g, the rebate coupon number of registration that can provide in the term of validity of rebate coupon is registered in the number of registration storage area.When in step 662h, being chosen in the shop clearing and in step 662i, there is no need to send data, if in step 662j, there are date, price or the rebate coupon of buying product, number of registration and discounted cost are recorded in the BC mode storing portion.
Turn back to step 66i, user's access stores and utilize bar code 751 shows cellular phone numbers, product IDs, rebate coupon number of registration and discounted cost etc. in the display part 590 of cellular phone 501.Then, in step 660k, bar code reader 708 reading out datas, and when finishing checking by the POS terminal, pay.If rebate coupon is arranged, can obtain product by discounted cost.
This method has and need not to carry out any transmission by cellular phone, just can finish the effect of electronically validating/purchase system.In this method, owing to not needing cellular phone, also portable TV and display packing of the present invention can be combined this business prototype of realization.Utilize this method, also can from general domestic television set, obtain rebate coupon number of registration etc., on the radio channel such as bluetooth, utilize the BC pattern that log-on data is sent to cellular phone 501 from the TV machine, cellular phone is taken to the shop, buy the product such as air ticket or admission ticket.
(6-7) utilize the bar code pattern to buy the example of product or service
Then, illustrate under the BC pattern, buy the object lesson of the process of product or service.Figure 40 and Figure 41 are the flow charts of buying service.In step 663a, receive data broadcasting " CDE ", and in step 663b, show product purchase menu screen 664a.In step 663c, if from the dish odd numbers, selected, for example, " 2 ", so, display menu number is 2 the 1st screen 664b in 663d, and rebate coupon benefit information be shown as shown in the figure like that.If selected rebate coupon in step 663e1, so, in step 663e2, the rebate coupon number of registration is provided at purchase program or granting center.In step 663f, utilize program or down link to receive the rebate coupon number of registration, and the rebate coupon number of registration is recorded in the number of registration memory with product IDs.
Then, in step 663h, the 2nd screen of display menu n on screen 664c.When using rebate coupon, screen 664c shows net cash and discount amount.When in step 663i, specifying clearing form, such as the registration control number the BC-4 be shown as shown in screen 664d is upper like that, be recorded in the number of registration storage area, with in step 663j, rebate coupon number of registration, discount amount and product IDs are recorded in the number of registration storage area.
Among the step 665a in Figure 41, open BC mode switch (SW) 736 (Figure 31), process forwards step 665b to, reads all log-on datas of BC pattern registration control number.With a part of data in the tabulation are shown as shown in the screen 666a like that.If selecting the registration control number in step 665c is the data of m (for example, No. 3), show the screen that does not have bar code at screen 666b.
Here, when in step 665d, when pressing the BC Mode S W736 shown in Figure 31 (b), open the BC pattern, and in step 665e, n=0 is set, in step 665f, n is added 1.In step 665g, show the n bar code.In the first situation, shown in screen 666b is upper, with when in step 665h, optical detection part divides 725 (Figure 31) to detect to read the light time, and process forwards step 665j to, and after certain duration, forward step 665k to, and if n is not end value, process turns back to step 665f and n is added 1.By the way, even in step 665h, the result is " negating ", and process also forwards step 665i to, opens BC Mode S W736, then, forwards step 665k to, and n is added 1 and show next bar code.
In this case, make at certain intervals bar code circulate constantly to show that the bar code such as the 1st, the 2nd, the 3rd, the 4th is not a kind of effective method, still, guarantee along with time lapse, all bar codes are all read.
According to the present invention, can utilize bar code reader now, read simply the display part of cellular phone, the checking that just can get used to by word of mouth or utilize a piece of paper or credit card to carry out, therefore, the present invention has improved convenience.
(6-8) be applied to portable TV receiver
Figure 42 has shown that display device of the present invention is applied to not have the example of situation of the portable TV receiver of portable sending/receiving function.Portable TV receiver 753 has the configuration that the transmission/reception section of removing cellular phone in the configuration from the calcspar of Figure 37 obtains, and therefore, omits calcspar.Shown in Figure 42 (a), portable TV receiver 753 contains display part 590 and secondary display part 592.Also can be furnished with BC (bar code) the model SW736 that makes bar code 751 obtain showing.
The below utilizes the BC flow for displaying figure among Figure 42 (b), and the process of the contract price of payment data broadcasting is described.Figure 42 (b) is basically identical with flow chart among Figure 40 and Figure 41.The disbursement and sattlement program with will pass through in advance data broadcast with the information of the corresponding relevant payment of device id, from data broadcast CDE, download.Illustrated as the latter half of utilizing Figure 30, only by broadcast reception, just can carry out electronics and buy processing.Therefore, with the explanation of omitting some stages, and, will begin explanation from the stage that the in advance data that are used for payment have been prepared.
At first, among the step 668a in Figure 42 (b), press and open BC Mode S W736, menu screen occurs, with when selecting the i menu (step 668b), in step 668c, n=0 is set, with in step 668d, n is added 1, n BC (step 668e) appears.Screen 668 has shown as n=1 with the form of bar code 751 and has shown the POS readout code: the situation during 2436 data.
If also do not pass through certain hour in step 668f, process turns back to step 668d, and n is added 1 and show next bar code.If in step 668f, passed through certain hour and in step 668g n reach end value, that is to say, when all bar codes all obtain showing, process forwards step 668h to, if check that loop No. and it are m or less, process forwards step 668n to, show No. 1 the bar code to last number corresponding with a circulation of bar code, and, when having finished circulation time m time, process forwards step 668i to and continues the show bar shape code, until the user inputs the symbol that the indication process has been finished.When finishing instruction arrival, finish the demonstration (step 668j) of BC.
Because the system among Figure 42 can only be made of receiver, bar code display of the present invention system extends to widely and uses.For example, when the user takes cheap shop payment electricity charge bill to this receiving terminal, the bar code reader reading out data, and, only in this way do, could input expense, subscriber number and payment month etc., in case payment is just carried out electronic accounting and is told Utilities Electric Co. reimbursement of expense.So far, the present invention has saved some payment step, thereby has saved manpower and materials.
(6-9) the bar code display method 2
Figure 43 has shown the more specifically method of the bar code shown in Figure 42 (b).At first, will utilize Figure 43 (a) that the method is described.In the step 668e of Figure 42 (b), on the secondary display part that is under " not showing " state, time T 1 interior demonstration the 1st bar code 751a and the 752a (Figure 43) in step 668f.If in step 668g, n is not end value, so, shows " not showing (non-display) " 757a in step 668k.When in step 668m during than the short certain time interval T 2 interior show bar shape code of T1, in step 668d and 668e, in time T 1 (step 668f), show the 2nd bar code 751b and 752b, and in time T 2 (step 668m), show " not showing " 757b.When the demonstration of last n bar code 751 is finished, if in step 668h, circulation is before the m time circulation, in step 668n, " do not show " 757z in the time T 3 longer than T2 (step 668p) " not showing " interval 754 interior demonstrations, and in interval T 1755a, again show the 1st bar code 1.Repeat this process m time.
Also can independent show bar shape code 751a or bar code 752a.Perhaps, just as shown in FIG., also can while show bar shape code 751a and bar code 752a.The data that show simultaneously identical content on bar code 751a and bar code 752a have the effect that the data of making can be read by one-dimensional bar code reader and two-dimensional bar reader.In this case, shown in Figure 43 (a), bar code 751a and bar code 752a have shown n kind pattern, and still, because two-dimensional bar has larger demonstration data volume, its shows K kind pattern, and wherein, K is less than n (that is to say n〉K).This makes K/n that the displaying time of bar code 752 becomes T1 doubly, thereby, make the identification of bar code more reliable.
Shown in Figure 43 (b), only the beginning in circulation just provides " not showing " 757z, and, by any " not showing " interval is not provided between all the other bar code 751a, 751b and 751d, can accelerate to show.
By " not showing " interval 756a, 756b and 756c is provided, the present invention can reduce the wrong identification of bar code.In general, the sweep type bar code reader of laser scanner, manual scanning device or dimension sensor and so on is arranged, these bar code readers have consisted of main flow.If the scan period that is presented at of bar code, change occured suddenly, for example, the first half is read bar code 1, and later half is read bar code 2, and the result is to have read diverse bar code.Certainly, by mistake, can eliminate most of mistake, still, be difficult to eliminate fully institute wrong.In addition, the retry that is caused by these mistakes will take time to read.
As in the present invention, with T1〉mode of T2 provides the read error that " not having to show " interval 756 time between bar code 1 and the bar code 2 of can significantly reducing crosstalks and cause between the demonstration interval of the demonstration interval of bar code 1 and bar code 2.In addition, for T3 (T3〉T2), show " not showing " 757z in the beginning of each circulation.Then, at during read, the bar code reader Measuring Time, thereby, can detect beginning bar code 1 751a, and, the effect of the beginning data of being convenient to detect synchronously sense data had." not showing " screen in this case can be black screen and white screen.White screen is not have signal, and is therefore, more effective aspect noise.
In addition, as shown in figure 44, insert the bar code 751a comprise opening code and 752a so that can detect beginning and detect synchronously in beginning, and, have and accelerate and guarantee the effect that data read.In this case, as shown in figure 44, all between bar code " do not show " that interval T 2 ' all possibility is identical.
In addition, in the beginning of bar code 751a and 752a, the specific part of bar code 751a and 752a, or the beginning of demodulating data shows the DISPLAY ORDER numbers 759 of indication circulation DISPLAY ORDER and always shows several 760.Like this, carrying out during read by bar code reader, even bar code reader manages only partly to read the 751b that shows as second by chance, also can be stored in information in the bar code reader relevant with DISPLAY ORDER numbers 759, check successively DISPLAY ORDER numbers 759 and read all data corresponding with total demonstration several 760.
This method makes random bar code obtain part and reads, and therefore, has the total data of acceleration and reads the effect of time.In this case, data structure 762 pictures of each bar code display as shown in Figure 44.That is to say, simultaneous display 761, DISPLAY ORDER numbers 759, always show several 760, data 764 and finish to show that 763 is arranged sequentially according to this.
When reading of all bar codes finished, the buzz that conventional bar code reader 708 (Figure 30) output indication finishes.This end-sound is to utilize microphone shown in Figure 21 594 inputs, detected by testing circuit, and, detect by this way and read end, therefore, after certain hour, on screen or by flashing lamp, show done state, perhaps, from loud speaker 753 end of output buzzs, inform the user with sound and demonstration.After certain hour, the operation of end loop type bar code display.
Figure 45 (a), (b) and (c) shown the reflection light quantity of bar code and detection signal.Illustrated as utilizing Figure 44, there be two types " not showing ": white displays and black display.Figure 45 (a) has shown with black display demonstration " not demonstration " 758, has replaced the white displays among Figure 43.Shown in Figure 45 (b), during the not demonstration of bar code, no longer there is signal.In the situation that the conventional barcode read operation when manually reading several bar codes, if bar code reader leaves Product labelling, so, does not have reverberation to return, therefore, output reflection light detecting signal no longer.
According to the display packing among Figure 45, in the situation that bar code reader leaves, signal level has reduced, and does not perhaps have bar code display within this " shows " interval 765.This makes conventional bar code reader be easier to read and is connected on " not having to show " interval 765 signal afterwards, it is identified as new bar code.During read bar code reader carries out in order to read printed bar code shows several bar codes of the present invention circularly even this method has, and also can read no problemly, and improve compatible effect.
Need not to be equipped with optical detection part and divide 725, by optimizing T1 according to bar code reader, this method is reliably read bar code.When before the user is obtaining the approval of POS terminal, pressing the BC switch at once, tens of times of bar code circulation, and data reading is come in the front that makes bar code reader just in time be fixed on the display part.When reading when finishing, the POS terminal is utilized the circular such as buzz to read and is finished, and therefore, the user can press the BC switch, and the continuation that stops bar code showing.Then, the user is presented at price on the POS terminal by payment, can buy product or service with the rebate coupon discounted cost.
Buy in the situation that utilize cellular phone of the present invention, when the user buys, for example, during valuables as jewel, the user sends to the center to verification msg, then, authentication center is made a phone call or is carried out packet communication with telephone number or the URL of cellular phone, thereby, tell cellular phone with the arrival sound, perhaps, the Validation Code that sends from authentication center recently with bar code display.Bar code reader reads this bar code and it is resend authentication center, again verifies, thereby, can realize verifying the clearing with high security.
In the situation that this cellular phone is stolen, when pressing the BC switch, request input password if the password of input is wrong, is arranged to be forbidden to enter the bar code display circulation to system.This processing has prevented the errors validity that causes because cellular phone is stolen.Therefore, can realize the confidentiality more much higher than current access.
People have also proposed to have the effect similar to those effects of the present invention, but the verification system with different system, but all such systems all need in addition new equipment to be introduced in the POS terminal.But the present invention makes the current plain edition bar code that is installed in many shops, the whole world can read bar code.Therefore, a bit need to change the infrastructure of legacy equipment in such shop etc., just can realize the present invention.So just produced very high economic benefit.In addition, the user only need to press the BC mode switch in the shop, do not need extra traditional operation or input, thereby, simplified checking or settlement process, and, convenience obviously improved.
Then, illustrating that the bar code that makes LCD of the present invention unit reads reaches optimal conditions stable, LCD element characteristics aspect.Because display part of the present invention is read by bar code reader, several unit need to satisfy certain condition.At first be spacing: L.During printing, printing conventional bar code needs 100dpi or higher printing density.This is corresponding to the spacing of 250 μ m, therefore, is L along the spacing L of horizontal direction〉250 μ m.The present invention has realized the bar code readable demonstration by forming bar code with 250 μ m or less horizontal interval.
In addition, will the optimum condition of relevant contrast ratio be described.In the situation that paper printing, definition OD (optical density) value.The OD value of the common printed paper that bar code printing is required is defined as 0.7 to 1.6.That is to say the OD value〉the 0.7th, optimum condition.Because the OD value represents with the logarithm representation, when OD being risen when converting contrast ratio to, if contrast ratio is 4, that is to say, LCD display unit of the present invention is accurately read by bar code reader, so, when from the angle of reflected value, can be arranged to 4 or higher to contrast ratio.From above-mentioned explanation, can find out, at horizontal pixel pitch L＜250 μ m and the contrast ratio CR during reflecting under 4 these two conditions, display unit of the present invention is set.So just guaranteed to read at the stable of during read.
In the situation of complete transparent type LCD unit without any the reflector of back of the body lighting system, be difficult to read bar code.But, the present invention is applied to the LCD display unit that part is furnished with reflector or semitransparent type reflector allows to utilize bar code to read.When from catoptrical angle, in this case condition setting is become CR〉4 make bar code reader can stably read it.
