Embodiment 1

[0071] Embodiment 1. When A-RACF is used as the final policy decision point, the bearer layer network entity IP EDGE or AN applies to A-RACF for multicast bearer resources after receiving the user's request to join a multicast group; According to the policies and resource conditions on the access side, the multicast bearer resource access authorization and resource reservation on the access side are performed. Optionally, the A-RACF may also apply for core network multicast bearer resources from the SPDF / C-RACF. A-RACF returns the final response to the bearer layer according to the situation of the access side or the application result of the comprehensive network. see Figure 7 shown, including the following steps:

[0072] (1), IP EDGE / AN receives the user's request to join the multicast group, obtains the multicast group address and user IP address that the user expects to join from the request, and may also obtain the multicast source address (one or more), And source a...

Embodiment 2

[0082] Embodiment 2, when A-RACF is used as the final policy decision point, when the bearer layer network entity IPEDGE / AN receives a request from the user to change the multicast source address or other signaling messages that cause resource changes, the IP EDGE / AN will send The A-RACF initiates a change request of the multicast bearer resource, and the A-RACF performs the access authorization and resource change of the multicast bearer resource change on the access side. Optionally, the A-RACF also requests the SPDF / C-RACF to change the core network multicast bearer resources. Finally, A-RACF returns the result response of resource change to IP EDGE / AN. see Figure 8 shown, including the following steps:

[0083] (1), IP EDGE / AN receives the user's request to change the multicast source address or receives other signaling messages that cause resource changes, obtains the user's IP address from the request, and may obtain the multicast source address requested to be change...

Embodiment 3

[0090] Embodiment 3. When A-RACF is used as the final policy decision point, when the bearer layer network entity IPEDGE / AN receives a request from a user to leave the multicast group or detects that the user has left the multicast group abnormally, the IP EDGE / AN A release request of the multicast bearer resource will be initiated to the A-RACF, and the A-RACF will release the access network, or the multicast bearer resource of the access network and the access aggregation network. Optionally, the A-RACF may also request the SPDF / C-RACF to release core network resources. Finally, the A-RACF returns a resource release response to the IP EDGE / AN. see Figure 9 shown, including the following steps:

[0091] (1) When IP EDGE / AN receives a request from a user to leave a certain multicast group or detects that a user has left a multicast group abnormally, it obtains the address of the multicast group that the user wants to leave and the user IP address from the request.

Abstract

The invention discloses a method, a system and an apparatus for implementing multicast load-bearing resource control, which applies RACS to implement the control of multicast load-bearing resource. The method comprises the following steps: service-based policy decision function (SPDF) entities receive control requests from multicast load-bearing resource of load-bearing layer network entities; and the SPDF entities implement the control of multicast load-bearing resource. The implementation of the control of multicast load-bearing resource performed by the SPDF entities comprises the steps that the SPDF entities apply an admission on the authorization and resource reservation for multicast bearer resource of an access side from an Access-Resource and Admission Control Function (A-RACF); and the SPDF entities apply an admission on the authorization and resource reservation for multicast bearer resource of a core network from a Core-RACF (C-RACF).

Description

technical field [0001] The present invention relates to the communication field and the network field, in particular to a control method, device and system for multicast bearer resources. Background technique [0002] The IPTV service is based on the broadband IP network and mainly streams media. Compared with traditional TV, IPTV can provide richer and more flexible services, provide a comprehensive IPTV value-added service platform, and realize communication, data, video, audio and other services. The live / broadcast television service (LTV / BTV) in IPTV needs to send data generated by one source node to multiple destination nodes, that is, point-to-multipoint communication. At present, the most effective solution for point-to-multipoint communication is multicast technology, which can effectively utilize network bandwidth and avoid wasting bandwidth resources. [0003] Related technologies 1. In order to support the multicast technology, the RACS (Resource and Admission C...
