Fig. 4 is a flow chart of realizing the MCBC business in the embodiment of the invention 1 in the WiMAX network.Referring to Fig. 3 A and Fig. 4, at business scenario once, the present invention realizes that in the WiMAX network process of MCBC business may further comprise the steps:

Step 401:SS/MS sends service discovering message by the H-MBSC of interface R2 in Home NSP.

In this step, service discovering message can be the discovery message that multicast is found (MCBC Discovery) message or other business.Carry information such as MCBC business list that SS/MS will obtain such as MCBC listing in the service discovering message.

In addition, base station BS that also carries SS/MS in the described service discovering message and inserted and the sign of HomeNSP are BS ID and NSP ID, and, also carry SS/MS ID.

After step 402:H-MBSC receives service discovering message,, determine the MCBC business of the Home NSP that this base station that the user connects need customize according to BS ID in this message and NSP ID.

Step 403: local MBSC is that H-MBSC is carried at business list and corresponding MCBC information source sign in the service discovering response message, is sent to SS/MS by Interface R2.

Here, in step 401, find message if service discovering message is multicast, so, in this step, described service discovering response message is that multicast is found response (MCBC DiscoveryResponse) message.

Step 404:SS/MS selects program of customization according to business list in the service discovering response message and MCBC information source identification list, and selects corresponding MCBC information source sign.

Step 405:SS/MS is carried at programme information and the selected MCBC information source sign that is customized in MCBC business description (the MCBC Service Subscription) message, is sent to H-MBSC by Interface R2.

Step 406:H-MBSC creates the MCBC service bearer path corresponding to this MCBC information source.

In step 405, MBSC judges whether to exist the MCBC service bearer path corresponding to this MCBC information source according to receiving MCBC information source sign, if, then direct execution in step 407, and need not again execution in step 406, if there is no, execution in step 406 at first then.

Step 407:H-MBSC describes response (MCBC SubscriptionResponse) message by Interface R2 with MCBC and is sent to SS/MS.

Here, after SS/MS receives MCBC Subscription Response message, can know that then service bearer created success.

Step 408:SS/MS is sent to H-MBSC by Interface R2 with the MCBC service request (MCBC Service Request) of carrying MCBC information source sign.

Step 409:H-MBSC by the bearer path that creates, sends to SS/MS with this MCBC information source corresponding service stream according to the sign of the MCBC information source in the MCBC service request.

Here, if H-MBSC self does not have the desired Business Stream of SS/MS, then in this step, before Business Stream was sent to SS/MS, H-MBSC need be from local MCBC information source acquisition request Business Stream.

In addition, the implementation procedure of this step mainly comprises: H-MBSC is by querying replicated tabulation, for SS/MS duplicates this MCBC information source corresponding service stream, and bearer path by creating, MCBC information source corresponding service stream is sent to MBSF among the ASN-GW, and the MBSF among the ASN-GW is by querying replicated tabulation, for SS/MS duplicates this MCBC information source corresponding service stream, and sending to MBSF among the BS, the MBSF among this BS sends to SS/MS with MCBC information source corresponding service stream again.

Step 602:H-PF carries out the MCBC operational decision making, according to the user contracting data of the SS ID match query correspondence in the MCBC request that receives.

Step 603: after the match is successful, the MCBC request (MBS-Request) that H-PF will carry SS ID and MCBC information source sign by Interface R3 was sent to the MBSF among the ASN-GW, and the MCBC service channel is set up in request.

MBSF among the step 604:ASN-GW is according to the MCBC information source sign that receives in the MCBC request, with the service channel of PF foundation corresponding to this MCBC information source.

MBSF among the step 605:ASN-GW is by checking local policy, and the MCBC request (MBS-Request) that will carry SS ID and MCBC information source sign by the R6 interface is sent to the MBSF among the BS, and the MCBC service channel is set up in request.

MBSF among the step 606:BS admits control decision according to local resource, and according to the MCBC information source sign that receives in the MCBC request, with the service channel of ASN-GW foundation corresponding to this MCBC information source.

Step 607: when having had the MCBC channel corresponding with the MCBC information source with described MCBC information source sign under the MBSF among the BS, the MBSF among the BS adds this corresponding MCBC channel by MCA-Req message informing SS/MS; When not having the MCBC channel corresponding with the MCBC information source with described MCBC information source sign under the MBSF among the BS, the MBSF among the BS is by the MCBC channel of DSA-Req notice SS/MS establishment corresponding to this MCBC information source.

Step 608:SS/MS is sent to MBSF among the BS with MCA-Response response message or DSA-Response response message.

MBSF among the step 609:BS is sent to MBSF among the ASN-GW with MCBC response message MBS-Response.
