Description
Technical field
The present invention relates to field of mobile communication, CDMA (code division multiple access particularly, Code DivisionMultiple Access) in the system, one provenance RNC (radio network controller, Radio networkcontroller) transmits UE (subscriber equipment: User Equipment) whether added the method for MBMS (multimedia broadcasting and multicast service, Multimedia Broadcast Multicast Service) multicast service indication information to Target RNC.
Background technology
Along with popularizing of large-screen multi-functional mobile phone, the application of mobile data services more and more widely, the demand of mobile communication no longer is satisfied with phone, message and surfing Internet with cell phone browse service, in order to effectively utilize mobile network resource, 3GPP (the 3rd generation partner project, Third Generation PartnershipProject) MBMS has been proposed, in the mobile network, provide a data source to send the point-to-multipoint service of data to a plurality of users, the realization Internet resources are shared, improve utilization rate of network resource, the especially Bao Gui interface resource of eating dishes without rice or wine.The MBMS business is a kind of shared network resource transmits data to a plurality of targets from a data source a technology, the MBMS of 3GPP definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business providing multiple rich video, audio frequency and multimedia service.
The MBMS business comprises multicast service (Multicast Service) and broadcasting service (BroadcastService).Each multicast service all needs Joining (adding) process, UE need pass through SGSN (Serving GPRS Support Node: Serving GPRS Support Node), GGSN (Gateway GPRS Support Node: Gateway GPRS Support Node) to BM-SC (broadcast multicast service center, Broadcast-Multicast Service Centre) activates certain multicast service, each multicast service for the UE adding, at UE, SGSN, GGSN, BM-SC all corresponding a MBMS UE context (MBMS UE Context), the details of corresponding multicast service have wherein been write down, when RNC and SGSN have set up PS (Packet Service, Packet Service) after the signaling in territory connects, SGSN issues RNC with the MBMS multicast service that UE adds, and RNC also sets up a MBMS UE context at each multicast service that UE adds; And for each broadcasting service, UE only needs local activation just passable, therefore only a MBMS UE context in the UE correspondence.Only exist and CS (Circuit Service at UE, Circuit Service) territory CN (core net: under the scene that signaling Core Network) connects, if the SRNS (service radio network system in CS territory takes place, Serving RadioNetwork System) reorientation, source RNC need tell Target RNC UE to add the MBMS multicast service, so that Target RNC continues as the service that UE provides the MBMS multicast service.
For this reason, as shown in Figure 1, the standard present according to 3GPP, in the SRNS repositioning process in CS territory, source RNC sends RELOCATION REQUIRED (reorientation requirement) message to the CN in CS territory, wherein carry Source RNC To Target RNC Transparent Container (source RNC gives the transparent transmission container of Target RNC) information, the CN in CS territory sends RELOCATION REQUEST (re-positioning request) message to Target RNC after receiving RELOCATIONREQUIRED message again, wherein carry Source RNC To Target RNC TransparentContainer information from source RNC, if UE has added the MBMS multicast service, source RNC utilizes Source RNCTo Target RNC Transparent Container information to bring Target RNC via CN with the indication information that UE has added at least one MBMS multicast service.
As shown in Figure 2, in the present standard of 3GPP, the rule that source RNC fills in Source RNC To TargetRNC Transparent Container information is: if UE has added at least one MBMS multicast service, then be with optional cell " MBMS Linking Information " (MBMS link information) therein, and be with optional cell " MBMS joined information " (MBMS adds information) in the SRNS RELOCATION INFO information therein; Target RNC judges that the rule whether UE has added the MBMS multicast service is: if comprised optional cell " MBMS Linking Information " in the Source RNC To Target RNCTransparent Container information, just judge that UE has added a MBMS multicast service at least, and for judgement that whether comprises optional cell " MBMS joined information " in the SRNS RELOCATIONINFO information and not explanation of processing.
This shows, source RNC transmits the problem whether UE added MBMS multicast service indication information to Target RNC and is in the present standard of 3GPP: source RNC uses simultaneously " MBMS joinedinformation " indicates UE whether to add the MBMS multicast service in optional cell " MBMS LinkingInformation " and the SRNS RELOCATION INFO information in Source RNC To TargetRNC Transparent Container information, and Target RNC only judges according to optional cell " MBMS Linking Information " whether UE has added the MBMS multicast service, not explanation of processing to another optional cell " MBMS joined information ", for Target RNC learn foundation that whether UE adds multicast service be simultaneously according to " MBMS joinedinformation " in " MBMS LinkingInformation " and the SRNS RELOCATION INFO information still a basis " MBMS Linking Information " become uncertain, the ambiguity that causes understanding.Carry " MBMS Linking Information " and " MBMSjoined information " simultaneously such as source RNC, and Target RNC is only judged according to one, then the information of transmitting exists redundant, if Target RNC is all handled 2 parameters, then need to judge 2 times and need do protection, increase the complexity that Target RNC is handled the consistency of 2 parameters; Perhaps source RNC only carries one of " MBMSLinking Information " and " MBMS joined information ", and the processing of Target RNC is to judge according to 2 parameters simultaneously, then can cause indication information to transmit mistake.
In fact Target RNC only just can learn according to one of " MBMS joined information " in " MBMS Linking Information " and the SRNSRELOCATION INFO information whether UE adds the MBMS multicast service.The parameter existence of therefore transmitting MBMS multicast service adding indication between existing protocol source RNC and Target RNC is redundant, and source RNC and Target RNC add the processing disunity of indicating to multicast service, have ambiguity, need clarification.
