Embodiment Construction

[0061] The basic principle of the present invention is to use SS as a multicast user when the multicast service is carried out, and use SS as a multicast control unit and a data replication unit. The multicast data is forwarded, and then the SS processes the multicast data and forwards it to the terminal.

[0062] The specific instructions are as follows:

[0063] Such as Figure 4 Said, the system of multicast service application in the embodiment of the present invention is made up of terminal (such as PC, TV+STB), SS, BS, multicast manager, communication network and multicast server, wherein:

[0064] The multicast server is responsible for sending multicast data to the communication network;

[0065] The communication network is used to distribute the multicast data sent by the multicast server to different BSs;

[0066] After receiving the multicast data, BS copies the multicast data to SS according to the instructions of the multicast manager;

[0067] The multicast ...

Abstract

The invention discloses a multicast business application method and system. The method comprises the following steps: a. configuring subscriber authority aiming at subscriber station SS by a multicast manager, receiving a request of joining a multicast group from the subscriber station SS by the multicast manager, performing authority authentication to the SS, if the authority passes, notifying an SIG module to forward the multicast data to the multicast group business flow by a data forwarding control module; b. controlling the SS to receive the multicast data by the multicast manager, and forwarding the received multicast data to a terminal by the SS. The invention overcomes the defect of the prior art, adopts the technology of using the basic unit SS which is accessed in the wireless wideband business as the multicast business, and the SS as a multicast control unit and a data reproduction unit, overcomes the drawback of crude business control brought by the sector as the multicast subscriber and mutual interference between the multicast subscribers in the prior art, and can satisfy the various operation demands of the multicast business.

Description

technical field [0001] The present invention relates to the technical field of broadband wireless access, in particular to the controllable multicast technology in broadband wireless access. Background technique [0002] WIMAX (World Interoperability for Microwave Access) is a wireless broadband access technology, a broadband wireless access device developed based on the WIMAX standard, and supports both wireless access and broadband services. IEEE 802.16 defines the technical standard of WIMAX, mainly defines the air interface physical layer (PHY) and medium access control layer (MAC) specifications of the wireless access system working in the 2-66GHz frequency band, and also related to the air interface protocol Conformance testing and coexistence specifications between different wireless access systems. [0003] According to whether it supports mobile features, IEEE 802.16 standards can be divided into fixed broadband wireless access air interface standards (the correspo...
