Method for collocating and receiving multi-broadcast service mapping message and its unit

Abstract

The invention relates to communication field and discloses a configuring method, a receiving method and a unit of multicast broadcast service mapping message, which realizes the macro diversity of MBS, enhances the receiving performance of MBS in the communication system. In the invention, the message unit of MBS transmits the physical layer parameter necessary for configuration of MBS mapping message MBS_MAP to all of the MBS operating units in one MBS field; the operating unit of MBS transmits the configured MBS_MAP to the receiving unit of MBS after configuring MBS_MAP based on the received physical layer parameter; the receiving unit of MBS receives MBS service based on MBS_MAP. The invention realizes the macro diversity of MBS in the radio network and enhances the receiving performance of MBS. When applied in WiMAX network, the management unit of MBS is a MBS agent, the operating unit of MBS is a base station, the receiving unit of MBS is a terminal.

Description

[0001] This application is a divisional application of China's earlier patent application "Method and System for Receiving Multicast Broadcast Service" and the application number of the earlier patent application is CN 200610137047.8, and the application date is October 18, 2006. technical field [0002] The invention relates to the communication field, in particular to multicast broadcasting technology. Background technique [0003] Nowadays, with the rapid development of the Internet, people's demand for mobile communication is no longer satisfied with telephone and message services, and a large number of multimedia services have emerged, some of which require multiple users to receive the same data at the same time, such as video on demand, TV, etc. Broadcasting, video conferencing, online education, interactive games, etc. Compared with general data, these mobile multimedia services have the characteristics of large data volume, long duration, and delay sensitivity. In ...

Problems solved by technology

However, for the multi-base station access scenario, if all base stations in an MBS domain need to implement macro-diversity on the air interface, the service data blocks corresponding to MBS_DATA_IE and Extended_MBS_DATA_IE in each MBS MAP message configured by each base station must be exactly the same, and At present, no specific implementation method has been provided to ensure that the service data blocks corresponding to MBS_DATA_IE and Extended_MBS_DATA_IE in each MBS_MAP message configured by each base station are exactly the same
