Embodiment Construction

[0078] 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.

[0079] In order to make full use of network resources and provide diversified services, the WiMAX network supports the broadcasting of MBS multicast broadcasting services. The present invention further proposes a conversion solution of the MBS service broadcasting mode, so as to realize flexible selection of PMP multicasting or PTP unicasting two modes for MBS broadcasting, so that MBS transmission can more fully utilize wireless resources.

[0080] The present invention judges whether to start the conversion process from PMP to PTP or from PTP to PMP according to the number of terminals by setting two threshold values. In the conversion process, the conversion process is realized completely through the message and interaction mechanism defined by the existing IEE...

Abstract

The invention relates to the wireless communication field, and discloses a broadcasting mode conversion method and a terminal switching method for the MBS business, and a base station. With the invention, the MBS business can be realized more efficiently. In the invention, two thresholds for the broadcasting mode to be converted from PTP to PMP or from PMP to PTP are arranged, and the whether the broadcasting mode is converted is ascertained based on the number of prior multicast group terminals, so different broadcasting modes can be selected flexibly based on the actual conditions. During the course of broadcasting mode conversion, the continuous conversion between PTP and PMP is realized through the CID change, the DSA / DSC message notice, the original CID release, the new CID mapping transmission, and other steps, so as to guarantee the continuity and reliability of the MBS business. Aimed at the broadcasting mode conversion in the BS switching course, a prepared switching method and an unprepared switching method are provided.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the multicast broadcasting technology in the microwave access global interoperability system. Background technique [0002] Worldwide Interoperability for Microwave Access ("WiMAX") is a wireless metropolitan area network technology based on the Institute of Electrical and Electronic Engineers ("IEEE") 802.16 standard. IEEE 802.16 is a working group specially set up to formulate wireless metropolitan area network standards. Since its establishment in 1999, this working group has been mainly responsible for the formulation of air interface standards for fixed wireless access. In order to promote wireless broadband access equipment based on IEEE 802.16 and the European Telecommunications Standards Organization's high-performance wireless metropolitan area network protocol, and ensure their compatibility and interoperability, in April 2001, the industry's main Entering manufac...
