Method, apparatus and system for controlling multicast bearer resources

摘要

A method, apparatus, and system for controlling multicast bearer resources are disclosed, which employ a resource and admission control subsystem (RACS) to control the multicast bearer resources. The method includes: a network entity in a RACS receives a request for controlling multicast bearer resources from a bearer-layer network entity and controls the multicast bearer resources. The network entity in the RACS includes: a receiving unit adapted to receive a request for controlling multicast bearer resources from a bearer-layer network entity and a control unit adapted to control the multicast bearer resources.
