Abstract
The present invention relates to a method in a telecommunication system for communication between mobile stations and base station sites in the telecommunication system. The mobile stations in said telecommunication system, preferably a cellular mobile radio system, move within a site on the same channel by use of seamless lobe or sector handover.
Description
The present invention relates to be used in a kind of telecommunication system at least one base station area method for communicating at mobile radio station and described telecommunication system.
Fig. 1 discloses the schematic diagram of flexible lobe orthopedic systems.Aerial array preferably has 8 antenna a period of time.
The channel of each frequency has its set of weights (W among Fig. 1 for example
1(1)-W
8(1)).The quantity of these weightings is the quantity decisions by used antenna a period of time.
The quantity of set of weights is that the quantity by synchronizing channel is determined.The channel of each frequency has one group of weighting, and if use SDMA (space division multiple access), a plurality of weighting settings for each frequency channels must be arranged here.
The quantity of the quantity=frequency channels of the set of weights * SDMA factor
The quantity in the quantity of the quantity=frequency channels of the composite weighted * SDMA factor * antenna a period of time
The lobe orthopedic systems of Fig. 1 is at the application 9601613-4 that is examining " method of translating cellular telephone system and configuration " (Method and Arrangement of Converting aCelluar Telecommunication System, applicant: radio design AB company), 9601615-9 " rotation wave beam cut-in method " (Rotating Lobe Access Method, radio design AB company) and 9601614-2 (Antenna system applicant:, the applicant: be described in detail radio design AB company), aforementioned application at this as a reference.
A problem of this flexible lobe orthopedic systems is to implement very expensive, and should be needs to use a lot of equipment.
Fig. 2 shows fixedly a less hardware cost and the low technical scheme that spends of lobe orthopedic systems.
The objective of the invention is to,, avoid the conversion of channel when handover for example is being when carrying out in the above mentioned fixedly lobe orthopedic systems.
Another object of the present invention is to avoid the conversion of receiver/transmitter apparatus in the base station area.
Above-mentioned purpose is by being used for realizing that at least one base station area method for communicating of mobile radio station and described telecommunication system wherein said mobile radio station moves by utilizing on the seamless lobe/channel of sector handover in described base station area in a kind of telecommunication system.
Handover without conversion emittor/receiver equipment means the increase capacity, because it produces better junction efficiency in base station area.
Other features of the present invention propose in the dependent claims.

Fig. 9-12 discloses the different structure according to lobe orthopedic systems of the present invention.
The present invention preferably relates to the handover between the lobe of not conversion channel.This means that portable terminal can move by utilizing on the same channel of seamless lobe handover in base station area.This handover is seamless, this means that it can not noted by the mobile subscriber.
The present invention is described with reference to Fig. 3-12.
Fig. 2 discloses a kind of implementation of Fig. 3 block diagram.TRX among Fig. 2 is corresponding to Fig. 3, the transmitter and receiver equipment among the 9-12.The LF1-LFn of Fig. 2 and antenna correspond respectively to and Fig. 3, equipment and the aerial array relevant with aerial array in 10 and 12.
Cellular mobile radio system of the present invention comprises a plurality of base station areas and mobile radio station (terminal).Each base station area has one or more sectors that are divided into a plurality of fixedly lobes (Fig. 4-8).Base station area comprises a plurality of base stations that have base station machine equipment and base station receiver equipment.Mobile radio station comprises mobile station receiver and mobile radio station transmitter.In cellular mobile radio system, the communication between base station area and the mobile radio station realizes by following step.As mentioned above, according to Fig. 2,3,9-12, each base station area utilize a plurality of fixedly lobes (Fig. 4-8).Setting up one between the emittor/receiver of base station area and mobile radio station is connected.A lobe in one of them sector of base station area is used for the signal transmission between the emittor/receiver of the emittor/receiver of base station area and mobile radio station.Base station area is measured the signal that receives from mobile radio station continuously.For example, base station area is compared by the signal that receives in the signal that will receive in actual lobe and another lobe, determines best lobe.This can realize by the received signal intensity in each lobe of comparison or by the signal-to-jamming ratio that relatively receives.
Comparison in this lobe between the signal strength signal intensity may mean the handover between the lobe.When carrying out handover, base station area transforms to another lobe of same base station area with the lobe that base station area utilized, and without the employed transmitter and receiver equipment of conversion, promptly base station area is used for new lobe with same emittor/receiver equipment.
In another embodiment of the present invention, when the conversion lobe, base station area is conversion emittor/receiver equipment also.
Thereby, when the conversion lobe, not conversion of channel.Should be realized that we represent frequency, time slot, CDMA coding etc. with channel.It should be understood that also except producing the handover between the aforesaid lobe, the handover between the sector also can be realized in a like fashion.
Multiple different handover case will at length be described with reference to Fig. 5-12.At first, the notion of " base station area " makes an explanation with reference to Fig. 6.The notion of " base station area " is defined as the area of coverage of three sectors among Fig. 6, and base station area comprises that usually by three aerial arrays of three base stations control, promptly a base station is used for an aerial array.
As mentioned above, handover (HO) can the different lobes in base station area between and carry out between the different sector.Disclosed as Fig. 5, a base station area can comprise three different actual antennas, and every all links to each other with the base station, and wherein handover can be carried out between these antenna (base station).Fig. 5, the situation in 11 is such, wherein lobe/sector handover 1 transforms to sector 2 and carries out from the sector.The emittor/receiver equipment of control sector 1 is transformed to another emittor/receiver equipment that is used for sector 2 during handover.Yet, use identical channel.
Fig. 5,9 have described another kind of possibility.In this case, lobe/sector handover 1 transforms to sector 2 and carries out from the sector, but has been to use the same emittor/receiver equipment of base station area.Also can use same channel or one other channel.
In Fig. 3 and Fig. 6, the handover in the sector is performed and without conversion emittor/receiver equipment.Also can use the channel of same or conversion.
In Fig. 6 and Figure 12, sector/lobe handover is from a sector and corresponding TRX1 is transformed to another sector and corresponding TRX2 carries out.Also can use the channel of same or conversion.
In Fig. 3 and Fig. 7, the lobe handover between the lobe 4 and 5 is carried out in a sector, and perhaps lobe/sector handover is carried out between sector 6 and 7, wherein carries out the handover of lobe 8 from sector 67 the lobe 9 to the sector.In this case, use same TRX equipment and can use equipment identical or conversion.
At Fig. 6, in 10, sector/lobe handover is to transform to the handover of another sector from a sector, but is to use the identical emittor/receiver equipment of base station area.
Foregoing description only is counted as preferential embodiment, and scope of the present invention is only limited by appending claims.
