Embodiment Construction

[0038] refer to figure 1 As shown, the WiMAX-based multicast system of the present invention includes: multicast service (or claim multicast multicast, MBS) controller, MBS content server, MBS content source, access service network gateway (ASNGW), base station (BS) , multicast router (MR), and AAA (authentication, authorization, and accounting) server, their relationship and functions are as follows:

[0039] 1. MBS content provider (MBS Content Provider), which is the provider of MBS content, can be provided by a third-party content provider or the operator itself.

[0040] 2. The AAA server is used for authenticating, authorizing and charging the user or the MBS service, and providing the MBS controller with the information of the user signing the service.

[0041] 3. Multicast service (MBS) controller (MBS Controller), connected with AAA server and MBS content source, used for:

[0042] (1) Manage MBS session information, and provide session information for ASN, MS, and ...

Abstract

The disclosed method to realize multicast business in WiMAX system that composes by MBS content source, AAA server, MBS controller, MBS content server, base station and gateway, comprises: applying UE to obtain MBS information from MBS controller in system; initiating business request by a UE; adding user multicast node into group according to MBS information and sending MBS content to user.

Description

technical field [0001] The invention relates to the worldwide interoperability for microwave access (WiMAX) technology in the field of communication, in particular to a method and a system for providing multicast services in the WiMAX system. Background technique [0002] High-bandwidth multimedia applications, such as network video conferencing, network audio / video broadcasting, multimedia distance education, remote consultation, entertainment and personalized services, etc., have brought about a sharp consumption of bandwidth and network congestion. Solutions to alleviate network bottlenecks include: increasing interconnection bandwidth, changing network traffic structure, multicast technology, etc. Multicast technology has its unique advantages. In a multicast network, even if the number of users doubles, the backbone bandwidth will not increase Needs increase accordingly. [0003] The broadcast and multicast service (Broadcast Multicast Service, BCMCS) function in CDMA ...
