Description
Technical field
The present invention relates to field of mobile communication, be particularly related in 3-G (Generation Three mobile communication system), UE (UserEquipment, subscriber equipment) SRNS (Serving Radio Network Subsystem takes place, SRNS Serving Radio Network Subsystem) after the reorientation, on Target RNC (Radio network Controller, radio network controller), obtain the method for MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast-multicast service) multicast service.
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 (Third Generation Partnership Project, third generation partner project) the MBMS business 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, especially Bao Gui air interface resource.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 Broadcast Service (broadcasting service).Each multicast service all needs to add (Joining) process, UE need pass through SGSN (ServingGPRS Support Node, the GPRS serving GPRS support node), GGSN (Gateway GPRS SupportNode, GGSN) to BM-SC (Broadcast-Multicast Service Centre, the BroadCast MultiCast Service center) activates certain multicast service, each multicast service for the UE adding, at UE, SGSN, GGSN, BM-SC all corresponding a MBMS UE context (MBMS UEContext), the details of corresponding multicast service have wherein been write down, when RNC and SGSN node have been set up PS (Packet Service, Packet Service) after the signaling in territory connects, the SGSN node is issued 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, and it is not within this paper discussion scope.Only exist and CS (Circuit Service at UE, Circuit Service) territory CN (Core Net work, core net) under the scene that signaling connects, if the SRNS reorientation in CS territory takes place, 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, the SRNS repositioning process in CS territory comprises the steps that this SRNS reorientation is initiated by source RNC:
1, source RNC sends RELOCATION REQUIRED (reorientation requirement) message to the CN in CS territory, wherein carries Source RNC To Target RNC Transparent Container (source RNC gives the transparent transmission container of Target RNC) information.
2, the CN in CS territory sends RELOCATION REQUEST (re-positioning request) message to Target RNC after receiving RELOCATION REQUIRED message again, wherein carry Source RNC To Target RNC Transparent Container information from source RNC, if UE has added the MBMS multicast service, source RNC utilizes Source RNC To 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.
Shown in Figure 2 is that source RNC fills in Source RNC To Target RNC Transparent Container information, and Target RNC judges that whether UE has added the regular flow process of MBMS multicast service, is described below:
Step S201, RNC check whether UE has added the MBMS multicast service; Be execution in step S202 then, otherwise execution in step S203.
Step S202, in Source RNC To Target RNC Transparent Container information, comprise optional cell " MBMS Linking Information (MBMS link information) ", comprise optional cell " MBMS joined information (MBMS adds information) " in the SRNS RELOCATION INFO information therein simultaneously.
Step S203, in Source RNC To Target RNC Transparent Container information, do not comprise optional cell " MBMS Linking Information ", do not comprise optional cell " MBMS joined information " in the SRNSRELOCATION INFO information therein simultaneously.
Step S204, Target RNC check in the Source RNC To Target RNC TransparentContainer information whether comprise optional cell " MBMS joined information ", are execution in step S205 then; Otherwise execution in step S206.
Step S205 judges that UE has added a MBMS multicast service, then execution in step S207 at least.
Step S206 judges that UE does not add any MBMS multicast service, and then flow process finishes.
Step S207, Target RNC is initiated the uplink information exchange process, obtains the information of the MBMS multicast service of UE adding from the SGSN node.
Can draw such judgment rule from above-mentioned regular flow process: if UE has added at least one MBMS multicast service, then in Source RNC To Target RNC Transparent Container information, be with optional cell " MBMS Linking Information ", and be with optional cell " MBMS joined information " in the SRNSRELOCATION INFO information therein.Target RNC judges that the rule whether UE has added the MBMS multicast service is: if comprised optional cell " MBMS LinkingInformation " in the Source RNC ToTarget RNC Transparent Container information, just can judge that UE has added a MBMS multicast service at least.
The standard present according to 3GPP, Target RNC can only learn that UE has added the MBMS multicast service from Source RNC To Target RNCTransparent Container information, but does not know which MBMS multicast service UE has added.For this reason, Target RNC needs at the IMSI that has obtained UE (International Mobile Subscriber Identity, international mobile subscriber identity) back obtains the information of each MBMS multicast service of UE adding by the uplink information exchange process from the SGSN node.The uplink information exchange process is described below as shown in Figure 3:
Step 303, if the SGSN node is identical after the SRNS reorientation in pure CS territory, then owing to preserved the MBMS UE context of each multicast service correspondence of UE adding on the SGSN node, the SGSN node can be searched corresponding MBMS UE context according to IMSI, and therefrom extract the MBMS multicast service that UE adds, uplink information exchange response message to Target RNC returns success wherein comprises the MBMS multicast service that UE adds, and Target RNC obtains the multicast service success.
Step 304, if SGSN node difference after the SRNS reorientation in pure CS territory, then because the new SGSN node that Target RNC links to each other is not preserved the MBMSUE context of each multicast service correspondence of UE adding, the SGSN node can't be searched corresponding MBMS UE context according to IMSI, return the uplink information exchange response message of failure to Target RNC, wherein do not comprise the MBMS multicast service that UE adds, Target RNC obtains the multicast service failure.
The scene that changes at SGSN node after the SRNS reorientation in pure CS territory, must wait until that UE initiates RAU (Routing Area Update under Target RNC, Routing Area Update) request, after new SGSN node has obtained the multicast service of UE adding from old SGSN node, could write down corresponding MBMS UE context on the new SGSN node, only after new SGSN node was preserved the MBMSUE context, Target RNC was initiated the multicast service that uplink information exchange request could obtain UE.According to the 3GPP agreement, UE initiation RAU flow process and new SGSN node obtain the multicast service of UE from old SGSN node process is transparent to Target RNC, Target RNC does not also know when can successfully write down MBMS UE context on the new SGSN node, therefore can not determine the opportunity of initiating uplink information exchange request to new SGSN node, and the initiation of blindness is attempted repeatedly, the signaling traffic load that this has directly increased network node has reduced utilization rate of network resource.Therefore existing 3GPP agreement can not solve the above problems.
