Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] In the embodiment of the present invention, MBS bearers between MBS nodes are established according to service distribution information. The MBS node is at least one of the following: base station, gateway, MBS proxy, and MBS server.

[0052] Service distribution information consists of bearer relationships between upstream and downstream nodes of each layer, and the bearer relationships between upstream and downstream nodes can be pre-configured or dynamically maintained.

[0053] The bearers between upstream and downstream nodes are maintained according to their bearer relationships, including establishment and release of bearers. For a node whose bearer relationship is pre-configured, its bearer with each downstream node is established or released unifo...

Abstract

The disclosed method, system and network nodes for controlling, and distributing data make MBS data be accepted successfully, and carry out effective maintenance for the MBS session. The invention includes steps: maintaining service distribution information (SDI) in up and down stream nodes of MBS for a MBS service; SDI of MBS is composed of lists of down stream nodes correspondingto each node. Based on SDI, the method establishes and maintains relation between service load of corresponding MBS and data distribution. Based on the said relation, the method distributes service load of the MBS among nodes in up and down stream nodes of MBS. MBS distribution information is configured in advance and / or maintained dynamically. Establishment of service load is configured in advance and / or maintained dynamically. Relation for distributing data is configured in advance, distributed in default and / or maintained dynamically.

Description

technical field [0001] The invention relates to the communication field, in particular to multicast broadcasting technology. Background technique [0002] IEEE802.16 is a standard promulgated by the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, "IEEE" for short) in December 2001 for providing last-mile wireless broadband access in a metropolitan area network. [0003] At the same time, many equipment and component suppliers formed the organization of the Worldwide Interoperability for Microwave Access ("WiMAX") forum, the purpose of which is to ensure the compatibility and interoperability of broadband wireless access equipment. Operability, speeding up the deployment of broadband wireless networks based on the above-mentioned IEEE802.16 series standards. Therefore, under normal circumstances, a system that implements wireless broadband access specified in the 802.16 series standards is called a WiMAX system. [0004]...
