| ??>>Authorised?SNA?List | ??O | ||
| ??>>>Authorised?SNAs | ??1to<maxSNAs> | ||
| ??>>>>SNAC | ??M |
Table 1
Wherein, the Public Land Mobile Nerwork of UE use is authorized in " Authorised PLMN " expression; " PLMNIdentity " expression Public Land Mobile Nerwork (PLMN) sign; The shared network framework tabulation that " Authorised SNAs List " expression is authorized; The concrete shared network framework row that " Authorised SNA " expression is authorized; " SNAC " represents the shared network sign indicating number that each PLMN authorizes down." O " expression option wherein, " M " represents essential option.When UE inserted, core net can be determined the PLMN of this portable terminal mandate and the Shared Network Area under each PLMN according to the EIC equipment identification code of portable terminal.When UE carries out reorientation, above-mentioned cell is inserted into RELOCATION REQUEST message notice RNC.Perhaps, when between core net and RNC, sending public identifier message, above-mentioned cell is inserted in the public identifier message notifies RNC.RNC receives the cell that parses the Shared Network Area access information after the above-mentioned message, determine the private resource authorization message of the MBMS of UE according to the message of the shared network sign indicating number of the shared network framework of wherein Public Land Mobile Nerwork sign, user terminal, determine promptly UE has the MBMS right of asking under which SNA, the network area of being authorized, whether the business of being asked has the mandate of PTP etc.Certainly, also can be between core net and RNC directly finish notice to the private resource authorization message of the MBMS of the UE of RNC by the Shared Network Area access information.
Fig. 4 notifies RNC flow chart about UE private resource authorization conditions for packet data protocol context activation mode of the present invention, and as shown in Figure 4, PDP context activation flow process of the present invention comprises:
Step 41:UE sends to service packet wireless traffic support node (SGSN) and activates MBMS context request (Activate MBMS Context Request) message, and context is set up in request.
Step 42:SGSN sends to service universal grouping wireless business supporting node (GGSN) and sets up MBMS context request (Create MBMS Context Request) message, and the MBMS context is set up in request.
Step 43:GGSN sends MBMS authorization requests (MBMS Authorization Request) message to broadcast multicast service center (BM-SC).
Step 44: authorize and pass through, BM-SC returns MBMS authorization response (MBMSAuthorization Response) message to GGSN, carries shared network mandate (the MBMS SNAAccess Information) information of MBMS private resource in the message.BM-SC creates MBMS UE context.
Step 45:GGSN creates MBMS UE context, and sets up MBMS context response (Create MBMS Context Response) message to the SGSN transmission, carries MBMS SNAAccess Information in the message.
Step 46:SGSN offers RNC by UE link (MBMS UE Linking Request) request message with the UE context, carries MBMS SNA Access Information in the message.
Step 47:SGSN send to activate the MBMS context to UE and accepts (Activate MBMS ContextAccept) message, thereby sets up context linking for this UE.
Step 302:RNC is the private resource that UE determines MBMS based on the private resource authorization message of MBMS.
Begin or the MBMS session is carried out in the process send mode of RNC judgement sub-district in the MBMS session.Be specially: whether RNC adjudicates in this sub-district the UE that receives the MBMS business according to MBMS SNA Access Information the PTP mode of adopting, if have, then according to UE decision-making send mode in the sub-district, and then press the method for salary distribution of being made a strategic decision and authorize UE distribution MBMS private resource for each.If no, then adopt the PTM send mode, for each UE distributes public resource.
Perhaps, RNC if send mode is PTM, then is that all UE distribute public resources in the sub-district according to the send mode of making a strategic decision of UE number in the sub-district.If send mode is PTP, RNC distributes private resource according to MBMS SNAAccess Information for the UE that has authorized, does not distribute private resource for undelegated UE.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
