Description
Technical field
The present invention relates to a kind of technology of supporting mobile communication business, particularly a kind of system and method for in the GSM network, supporting the group service realization.
Background technology
Group service comprises that mainly speech group-calling service (VGCS), voice broadcast call business (VBS) etc. are professional.Wherein, realize that the process of VGCS business is: after travelling carriage (MS) was initiated the VGCS business, network side was set up group-calling channel in each sub-district in group call region, and went up transmission group calling notification message at notification channel (NCH, Notification Channel).Behind the notification message on the mobile phone detection NCH that belongs to this group, adjust on the group-calling channel automatically and listen to, when any travelling carriage is wanted to talk, begin speech by push-to-talk (PTT, PUSH TO TALK) key, unclamp the PTT talk key and ring off.Difference when realizing the process of VBS business and realizing the VGCS business is: in the VBS business, the promoter takies up speech all the time, and other users can only receive, and can not take up speech.
In the prior art, Global Link mobile communcations system (GSM, Globe System of MobileCommunication) group service in the network is realized based on the GSM03.68 agreement, according to the GSM03.68 agreement, the system that realizes group service comprises: MS, BSS, equipment of the core network etc., wherein, (the MSC of mobile switching centre, Mobile Switching Center), attaching position register (HLR, HomeLocation Register) equipment of the core network and base station sub-system (BSS such as, Base Station Subsystem) special Signalling exchange at group service is arranged in the A interface between the equipment, as VGCS/VBS (SETUP) message etc. is set, therefore realize group service in the prior art, need the common support of BSS equipment and equipment of the core network.
Fig. 1 is the system schematic that realizes group service in the prior art, this system comprises: MS11, BSS12, MSC15, user data library unit 16, wherein, BSS12 comprises: base transceiver station (BTS, Base Transceiver Station) 13 base station controller (BSC,, Base Station Controller) 14, BSC14 comprises: Signalling exchange unit 141; MSC15 comprises: Signalling exchange unit 151, verification unit 152, cluster data cell 153.
MS11, by with BSS12 in the mutual access network of BTS13.
Described cluster data cell 153 can provide the configuration data of VGCS and VBS, the group number that provides such as system, and the information such as attribute of each group.
User data library unit 16 receives the user data query information that verification unit 152 sends, and sends user data to verification unit 152.
Described user data library unit 16 can provide user's group service data, comprise whether the user supports the authorization checks such as concrete group number that group service, permission are initiated, and can be attaching position register entities such as (HLR, Home Location Register) in actual applications.
Fig. 2 is a process schematic diagram of realizing group service in the prior art, and this process comprises:
Step 201:MS by and BSS between information interaction, send layer three business request information to BSC.
Step 201 can comprise following steps: the MS channel request is given the BSS system; BSS assignment signalling channel sends immediate assignment message to MS; MS sends the message that comprises layer three service request to BSS.
Step 202:BSC decoding layer three types of service determine that type of service is a group service.
Step 203:BSC reports complete layer three message to MSC.
Step 204～step 205:MSC verified users authority, and send business to the user and accept message.
Usually according to the user data in the attaching position register customer data bases such as (HLR, Home Location Register), the user is initiated the authority of group service carries out verification to MSC, and after the user is by verification, sends layer three business to MS and accept message.
Step 206:MSC obtains the attribute of group according to the group number in the group call reference.
In the step 206, MSC visits the data configuration of group calling according to the group number in the group call reference, obtains the attribute of group.
Mutual VGCS/VBS message between step 207～step 209:MSC and the BSS is specially: MSC sends VGCS/VBS and (SETUP) message is set to BSS, sets up the group calling control connection; BSS sends VGCS/VBS SETUP response (ACK) message and gives MSC; MSC sends VGCS/VBS assignment (ASSIGNMENT) request (REQUEST) message and gives BSS.
The assignment request message number that MSC sends to BSS in the step 209 is identical with the sub-district number of group calling configuration, comprises cell global identification (CGI, Cell Global Identity) in the message.
Step 210:BSS sends a notification message in the sub-district of group call region.
The described transmission of step 210 is to send with the forms of broadcasting, comprises group number information etc. in the described notification message.
Step 211～step 212:BSS sends VGCS/VBS ASSIGNMENT to MSC and finishes (COMPLETE) message; MSC sends assignment request message to BSS.
The mutual assignment message of step 213:BSS and MS.
Step 213 can comprise following steps: BSS and send Assignment Command to caller MS, comprises the description of Traffic Channel in the message; MS access service channel, and report assignment to finish message to BSS.
Step 214～step 215:BSS reports assignment to finish message and gives MSC; MSC sends to BSC and connects (Connect) message.
Step 216:BSC sends connection message for caller MS.
Step 217:MS begins conversation.
In the prior art, utilize system shown in Figure 1, also can realize non cluster service, specifically: MS11 realizes non cluster service by Signalling exchange unit 151 interactive information of BSS12 and MSC15.Described non cluster service can be: point is exhaled business or GPRS (GPRS) etc.
In the step 202 shown in Figure 2, BSC decoding layer three types of service, if determine that type of service is a group service, then execution in step 203, if determine that type of service is a non cluster service, then finish the step that realizes non cluster service.The process of realization non cluster service comprises as shown in Figure 3 in the prior art:
Step 301: identical with step 201.
Step 302:BSC decoding layer three types of service determine that type of service is a non cluster service.
In the step 302, after BSC decoding layer three types of service, be group service if determine type of service, step 203 in the execution graph 2 then, otherwise execution in step 303.
Step 303:BSC reports complete layer three message to MSC.
Mutual non cluster service information between step 304:MSC and the MS.
When the described non cluster service of step 302 was exhaled business for point, step 304 can comprise following steps: MSC and send the layer three professional message that receives to MS; MS reports setting (SETUP) message to give MSC, comprising called party's number; MSC sends assignment request message to BSS; BSS sends Assignment Command to MS, comprises the description of Traffic Channel in the message; MS access service channel, and report assignment to finish message to BSS; BSS reports assignment to finish message and gives MSC; MSC sends ring (Alerting) message and gives MS; After MSC connects the called party, send Connect message for caller MS; MS sends Connect and replys (Ack) message to MSC; MS begins conversation.
The shortcoming of prior art is:
In the existing GSM network, equipment of the core network can be provided by different manufacturers with BSS equipment, and MSC can link the BSS equipment of different vendor simultaneously, most of equipment of the core network is not supported group service, according to the GSM03.68 agreement but at present,, when in the GSM network, realizing group service, must change simultaneously or equipment of the core network and BSS equipment such as the MSC that upgrades, HLR, and the cost of replacing or upgrading equipment of the core network is higher, causes the realization cost height of group service in the prior art.
