Embodiment Construction
[0025] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.
[0026] Fig. 2 is a block diagram of the composition of the WiMAX multicast broadcast service system according to the present invention. As shown in Figure 2, the system includes a terminal, an access service network and a connection service network, and the access service network includes the following MBS-related components:
[0027] The MBS server 244 located in the access service network gateway 208 can be divided into a control plane unit 2124 and a media plane unit 2126, a multicast router 246, and a unicast / multicast signaling control unit 224 and a scheduling and framing unit located in the base station Unit 226.
[0028] Among them, the unicast / multicast signaling control unit 224 of the base station is connected with the control plane unit 2124 of the MBS server to form the control plane function of the MBS, which is res...

The present invention provides a realizing system and a method for multicast broadcast. Therein, the realizing system the broadcast multi-service comprises an access service network, which comprises an MBS server accessed in the service network gateway, a multicast router, and a unicast / multicast signaling controlling unit and a framing dispatching unit of the base station, and therein, the MBS server is divided into a controlling surface unit and a media surface unit; at least a connection service network, which is used to perform the connection service; therein, the unicast / multicast signaling controlling unit of the base station and the controlling surface unit of the MBS server are connected to realize the controlling surface function, and the framing dispatching unit of the base station and the media surface unit of the MBS server are connected to realize the media surface function.
Description
technical field [0001] The invention relates to the communication field, in particular to a system and method for realizing multicast broadcasting services. Background technique [0002] MBS (Multi-broadcast Service, multicast broadcast service) is an important function of a wireless communication system defined by the IEEE802.16e protocol. MBS is divided into two situations: single base station access and multi-base station access. The former refers to the multicast broadcast service in a base station, and the latter refers to all terminals registered to the multicast broadcast content at the network level can receive MBSZone (MBS A multicast broadcast service transmitted synchronously by all base stations under the downlink connection. The MBS involved in this article is the multicast broadcast service of multiple base stations. [0003] The NWG specification of the WiMAX Forum defines the reference architecture of the end-to-end WiMAX network system. As shown in FIG. )...
