Description
Technical field
The present invention relates to call out access technology, be meant the method that called realization short calling is set up in a kind of wireless communication system especially.
Background technology
As everyone knows, according to the user object in mobile communication market, mobile communication can be divided into: public mobile communication and professional mobile communication two big classes.Accordingly, public mobile network is the service object towards entire society with the public users, and the purpose of public mobile network network construction is to provide required telecommunication service for public users; The specialty main To enterprises of mobile radio communication or industry user satisfies the needs of all departments' command scheduling and collaborative work.Usually, will be called cluster market towards industry or enterprise customer's mobile communication market, so, pairing industry or enterprise customer just are referred to as cluster user.At present, the main users in the domestic cluster market is: public safety, government utility, governability, public transport, postal service, oil/chemical industry, security personnel/delivery or the like, these clients have special demand to call setup speed.
For public mobile subscriber, call set-up time is long, as 3～10 seconds, can not cause too much influence; And the user of specific (special) requirements is arranged for some, as cluster user, then pay special attention to the call setup speed of communication system, because cluster user is in managing, need to prepare at any time to handle urgent accident, wish that communication system can accomplish that one pushes to talk after emergency takes place, just require call set-up time less than 0.3 second, otherwise may cause serious consequence.For example in railway applications, suppose that bullet train travels with 300 kilometers speed per hour, when the order snub that has an accident, braking commands arrived after 3 seconds, and train has rolled 250 meters away from; And braking commands arrived as 0.3 second, and train has only travelled 25 meters.Obviously, under this class situation, more guaranteed once the fail safe that pushes to talk to the emergency processing.In addition, the conversation characteristics of cluster user are: each duration is short, but voice frequency is higher.Because each cluster user all can insert again and again, so call proceeding speed has remarkable influence to the operating efficiency of whole group system.
In the evolution of cluster, also be to carry out the transition to digital cluster system from the simulation group system, existing digital cluster system is based on that current digital mobile communication network realizes.At present, public's digital mobile communication system of main flow is global mobile communication (GSM) system or code division multiple access (CDMA) system, its air interface is used the wireless-modulated mode of time division multiple access (TDMA) or code division multiple access (CDMA), and adopt the honeycomb mode to realize channeling, satisfy the demand that the mobile communication service is provided for a large amount of public users fully.Compare with the mobile cluster communication system of special use, owing to want problems such as taking into account system capacity, big geographic range networking, so the network equipment level of public mobile communication system is many, control such as paging, network insertion signaling more complicated.
With the gsm mobile communication system is example, GSM is that the Europe postal service is initiated to formulate at the beginning of the eighties in last century with telecommunications conference (CEPT), and the European mobile communication standard of being in charge of and revising by ETSI (ETSI), Fig. 1 is the networking structure schematic diagram of a simplification of gsm mobile communication system.As shown in Figure 1, gsm system comprises a plurality of functional entitys: mobile switching center (MSC/VLR), base station controller (BSC), base station transceiver (BTS), attaching position register (HLR) and short message service center (SMC) etc.Wherein, BSC and BTS are responsible for setting up Radio Link with travelling carriage; MSC/VLR is responsible for user's mobile management and service management; HLR is responsible for preserving and safeguarding the business information and the positional information of travelling carriage.
Based on structure shown in Figure 1, when certain mobile terminated the time, need carry out repeatedly Signalling exchange with network side and could set up calling.Suppose that travelling carriage A is called out as called, concrete signaling process flow process may further comprise the steps as shown in Figure 2:
Step 201～204: the MSC/VLR of network side is according to self record to travelling carriage A positional information, to base station sub-system (BSS) the transmission beep-page message PAGING of network side; After BSS receives, on paging channel, transmit paging request PAGING REQUEST to called mobile station A position district; After called mobile station A receives the paging request, on Random Access Channel, initiate channel request CHANNELREQUEST to BSS; BSS distributes special-purpose signaling channel for called mobile station A, and the Dedicated Signaling Channel that is distributed is passed through assignment IMMEDIATE ASSIGNMENT message informing called mobile station A immediately, so far finishes the foundation of wireless connections.Wherein, carry the channelling mode information such as (Channel Needed) of paged called mobile station sign (Mobile identity), page-mode (Page Mode), needs in the paging request.Described BSS comprises one or more BSC and BTS.
Behind the Dedicated Signaling Channel that step 205: called mobile station A obtains to distribute, on this Dedicated Signaling Channel, send page-response message PAGING RESPONSE, carry mobile station indicia (Mobile identity), travelling carriage class mark (Mobile station classmark), encryption key sequence number information such as (Ciphering key sequence number) in this page response to MSC/VLR.
After step 206～209:MSC/VLR receives the page response of called mobile station A, finish authentication and encryption mode setting operation to called mobile station A by Signalling exchange.Wherein, step 206 and 207 is finished authentication, carry encryption key sequence number (Ciphering key sequence number), authentication random number information such as (Authentication parameter RAND) in the authentication request, carry authenticating result parameter (Authentication parameter SRES) in the Authentication Response; Step 208 and 209 is finished the encryption mode setting, carry enciphered message (Encryption Information), encrypted response pattern information such as (CipherResponse Mode) in the encryption mode order, this encrypted response pattern is an optional parameters, and encryption mode is finished and carried selected encryption mechanism (Chosen Encryption Algorithm) in the message.
In actual applications, above-mentioned authentication ciphering flow process is optional.
Step 210～215:MSC/VLR makes a call to called mobile station A and sets up request SETUP; Called mobile station A loopback is called out and is confirmed that CALL CONFIRMED gives MSC/VLR;
Afterwards, MSC/VLR gives called mobile station A assignment Traffic Channel (TCH), and by Assignment Command ASSIGNMENT REQUEST notice BSS; After BSS receives, again the channel that is distributed is passed through Assignment Command ASSIGNMENT COMMAND message informing called mobile station A, shown in step 213,214.Wherein, mainly comprise in the Assignment Command message: channel type (Channel Type), circuit number information such as (CircuitIdentity Code).
Called mobile station A returns assignment to BSS and finishes ASSIGNMENTCOMPLETION after obtaining the Traffic Channel of assignment; BSS further transmits assignment to MSC/VLR again and finishes message.Described assignment is finished and is consisted predominantly of circuit pool (Circuit Pool) parameter in the message, and this parameter is optionally, if there are a plurality of circuit pool between MSC and the BSS, and BSS distributes under the situation of circuit between the MSC-BSC and needs to comprise this parameter.
Step 216～218: if the called mobile station A free time, then called mobile station A sends ALERTING message ALERTING and connection request CONNECT to network side; Network side issues connection response CONNECT ACKNOWLEDGE after receiving connection request, and network side is set up the speech channel between called mobile station A and the caller, and calling and called enter talking state.
Here, paging channel is organized by paging subchannel mode, different mobile subscribers may belong to different paging subchannels, consider the power problems of travelling carriage, each travelling carriage is only intercepted own affiliated paging subchannel, therefore during the request of network distributing paging, wait until when paging subchannel under the called mobile station arrives and just initiate.
From above-mentioned steps as can be seen, in order to improve wireless channel utilance and protecting network safety, telex network privacy, existing called signaling procedure is comparatively complicated in realization, so just causes the call proceeding time longer.But, owing to preparing to handle emergency at any time, very high on the one hand for special user such as cluster user to the requirement of call proceeding time, generally will be below 1 second; On the other hand, cluster user has been accustomed to simulating the mode of operation of PoC in the group system (PTT), so also require the mobile communication system towards cluster user, promptly digital cluster system also has the ability of calling out of setting up at short notice.Obviously, be to satisfy the requirement of setting up at present such as special user's short callings such as cluster users based on the wireless communication system of GSM or CDMA.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
For the public mobile communication system, owing to will consider capacity problem, institute thinks that the raising channel utilization introduced the signaling process of some relative complex; And for some special system such as group system, because what at first require is call proceeding speed, therefore can under the situation that reduces some channel utilizations, provide higher call proceeding speed, just improve systematic function by suitable sacrifice channel utilization.So basic thought of the present invention is exactly: simplify the business processing flow in the public mobile network, set up the complicated signaling that relates in the process and merge, to reduce mutual between called mobile terminal and the network to the travelling carriage termination is professional.
With the group system is example, considers the current cluster user based on voice call, and therefore, MSC/VLR can carry out channel assignment according to speech business in advance in beep-page message, and notice presently used A interface circuit of BSS and wireless channel type.Can be identified as the business that only needs signaling channel for MSC/VLR, as: short message service, in beep-page message, do not consider to carry out in advance channel assignment.After if called mobile terminal sends and calls out affirmation CALL CONFIRM signaling, MSC finds that the channel type of assignment in advance and the professional required channel type of this cluster user do not match, then can revise channelling mode by assignment process, shown in step 312 among Fig. 3～315, that is: MSC/VLR sends the Assignment Command ASSIGNMENT COMMAND that carries the assignment Traffic Channel to BSS; After BSS receives, to called mobile terminal transmitting channel schema modification CHANNEL MODE MODIFY; Called mobile terminal is replied CHANNEL MODE MODIFY ACKNOWLEDGE to BSS Return Channel schema modification; BSS returns assignment to MSC/VLR again and finishes ASSIGNMENT COMPLETE message.If but MSC/VLR shifts to an earlier date Traffic Channel and this professional required channel type coupling of assignment, then can save the signaling interaction time that channel assignment needs, thereby improve whole call proceeding speed.Here, portable terminal can be a travelling carriage.
Setting up calling with the network side called mobile station A corresponding with cluster user is example, and the call setup flow process of called mobile station A specifically comprises the steps: as shown in Figure 3
Step 301: the MSC/VLR of network side sends message paging command PAGING COMMAND according to self record to travelling carriage A positional information to the BSS of network side; Simultaneously, in paging command message, MSC/VLR indicates this professional wireless channel type and circuit number between the BSC-MSC (CIC) that uses to BSC.So, mainly comprise in the message paging command: the channelling mode (Channel Needed) of paged travelling carriage sign (Mobile identity), page-mode (Page Mode), needs, channel type (Channel Type), circuit number information such as (Circuit Identity Code).
After step 302～304:BSS receives the message paging command, on paging channel, send paging request PAGING REQUEST to called mobile station A position district; After called mobile station A receives the paging request, initiate channel request CHANNEL REQUEST to BSS on Random Access Channel, the content in this message is determined according to the Channel Needed parameter in the paging request message of receiving; When BSS receives that the parameter of ChannelRequest message is Full Rate only or Dual Rate only, BSS distributes special-purpose Traffic Channel for called mobile station A, and the Traffic Channel of being distributed is passed through assignment IMMEDIATEASSIGNMENT message informing called mobile station A immediately.
After step 305: called mobile station A obtains the Dedicated Signaling Channel of assignment, on this Dedicated Signaling Channel, send the PAGING ACKNOWLEDGE message that pages reply, carry mobile station indicia (Mobile identity), travelling carriage class mark parameters such as (Mobile station classmark) in this message that pages reply to MSC/VLR.
After step 306～309:MSC/VLR receives the message that pages reply, and carry out Signalling exchange between the called mobile station A, finish authentication, encryption flow called mobile station A.
Here, the specific implementation of authentication is like this: encryption key sequence number and authentication random number information that MSC/VLR will be used for authentication send to called mobile station A; After called mobile station A receives,,,, obtain authenticating result, the authenticating result parameter is returned MSC/VLR through specific authentication arithmetic as input parameter as encryption key Ki with authentication random number information and other travelling carriage security informations.
Whether the specific implementation of encrypting: needed to encrypt by MSC/VLR decision called mobile station, if do not need, then network side does not need to send any information relevant with encryption to called mobile station if being like this; If desired, then network side sends enciphered message to called mobile station A, comprise the selected cryptographic algorithm of network side in this information, after called mobile station A received, selected a kind of cryptographic algorithm returned to MSC/VLR or returns the information of not supporting cryptographic algorithm to MSC/VLR.
The authentication of step 306～309 and encryption flow are optional flow processs, can select to carry out or do not carry out according to the network needs.Under the situation of carrying out authentication ciphering, authentication and encryption flow can be carried out together; When called mobile station does not need to encrypt, also can only carry out authorizing procedure.
Step 310～311:MSC/VLR sends setup requests SETUP to called mobile station A, called mobile station A loopback is called out and is confirmed that CALL CONFIRMED gives MSC/VLR, and this calling carries the required bearing capacity of this call business of called mobile station A in confirming.
After MSC/VLR receives and calls out affirmation, according to calling out the bearing capacity of carrying in the affirmation CALL CONFIRMED message, judge whether the required traffic channel types of current called mobile station A is consistent with the traffic channel types of assignment, if not, after then MSC/VLR gives called mobile station A assignment Traffic Channel again, execution in step 312～315; Otherwise, direct execution in step 316～318.
Step 312～315:MSC/VLR sends the Assignment Command ASSIGNMENT REQUEST that carries again the assignment traffic channel information to BSS; After BSS receives, to called mobile station A transmitting channel schema modification CHANNEL MODE MODIFY message, with the Traffic Channel notice called mobile station A of new assignment; Called mobile station A replys CHANNEL MODE MODIFY ACKNOWLEDGE message to BSS Return Channel schema modification after obtaining new Traffic Channel; BSS returns assignment to MSC/VLR again and finishes ASSIGNMENT COMPLETE message.
Step 316～318: called mobile station A sends ALERTING message ALERTING and connection request CONNECT to MSC/VLR; After MSC/VLR receives connection request, issue connection response CONNECT ACKNOWLEDGE message to called mobile station A, called mobile station A sets up speech channel via network side and caller, and calling and called enter talking state.
In order further to simplify the professional flow process of setting up of travelling carriage termination, the present invention can also allow MSC/VLR that authentication, the request of encryption are sent to called mobile terminal with the paging request, correspondingly, called mobile terminal returns authentication, encrypted response to network side with page response, make Traffic Channel Assignment and authentication, encryption mode that flow process is set and carry out simultaneously, to save the time of call proceeding.Concrete handling process may further comprise the steps as shown in Figure 4:
Step 401～405: basic identical with the operation of step 301～305, just MSC/VLR further includes in the message paging command that network B SS sends: enciphered message (Encryption Information), encryption key sequence number (Ciphering key sequence number), authentication random number information such as (Authenticationparameter RAND), can also select to carry encrypted response pattern (Cipher ResponseMode) information; Correspondingly, called mobile station A further includes in the message that pages reply that MSC/VLR returns: encryption mechanism of selection (Chosen Encryption Algorithm) and authenticating result parameter parameters such as (Authentication parameter SRES).So, in the message paging command, carry Traffic Channel, authentication and encryption configuration information, can accelerate the professional processing speed of setting up flow process of travelling carriage termination.
Certainly, if only need finish authorizing procedure to called mobile station A, then MSC/VLR need not carry enciphered message in the message paging command that network B SS sends; Corresponding called travelling carriage A need not carry the encryption mechanism information of selection in the message that pages reply that MSC/VLR returns.
Equally, BSS also carries the corresponding authentication enciphered message in the paging request that called mobile station A sends, or authentication information.
Step 406～414: identical with the operating process of step 310～318.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
