Patent ID: 8264998

Claim:
A method for controlling multicast bearer resources, comprising: receiving, by a Service-based Policy Decision Function (SPDF), a request for controlling multicast bearer resources from a bearer-layer network entity; and controlling, by the SPDF, the multicast bearer resources; wherein, the process of controlling, by the SPDF, the multicast bearer resources comprises: applying, by the SPDF, to an Access-Resource and Admission Control Function (A-RACF), for the multicast bearer resources of an access side; and applying, by the SPDF, to a Core-Resource and Admission Control Function (C-RACF), for the multicast bearer resources of a core network; wherein the A-RACF receives a request for applying for the multicast bearer resources; if the request for applying for the multicast bearer resources does not contain bandwidth information, the A-RACF queries local configuration to obtain a bandwidth required by the multicast group.
