Abstract
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.
Claims20
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.
A network entity located in a Resource and Admission Control Subsystem, RACS, comprising:
- a receiving unit, adapted to receive a request for controlling multicast bearer resources from a bearer-layer network entity;
- a control unit, adapted to control the multicast bearer resources;
- wherein, the network entity is a Service-based Policy Decision Function (SPDF);
- and
- wherein the process of controlling the multicast bearer resources comprises:
- applying, to an Access-Resource and Admission Control Function (A-RACF), for the multicast bearer resources of an access side;
- and applying, 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.
A system for controlling multicast bearer resources, comprising:
- a bearer-layer network entity, adapted to initiate a request for controlling multicast bearer resources;
- and
- a Service-based Policy Decision Function (SPDF), adapted to receive the request for controlling the multicast bearer resources from the bearer-layer network entity, and control the multicast bearer resources;
- wherein the process of controlling the multicast bearer resources comprises:
- applying, to an Access-Resource and Admission Control Function (A-RACF), for multicast bearer resources of an access side;
- and applying, 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.
