Embodiment Construction

[0082] 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.

[0083] In the present invention, the base station transmits control information through the broadcast channel, multicast channel, transmission channel or multicast group channel defined by IEEE802.16e, including service control information change indication, service announcement, MBS service session start / end identifier, PTP and PTM mode switching instructions, statistical instructions, the terminal operates its MBS service according to the received control information.

[0084] The first embodiment of the present invention will be described below. The first embodiment of the present invention relates to a method for controlling MBS services, specifically as figure 2 shown.

[0085] In step 201, the base station sets corresponding MBS control information according...

Abstract

The invention makes base station possible to send control information of MBS service correctly. Through broadcast channel, multicast channel, transfer channel or channel of MBS multicast set, base station transfers MBS control information to terminals. The MBS control information can be the change indication of service control information, service announce, starting / ending ID of MBS service conversation, mode conversion indication of PTP and PTM, statistical indication etc.

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] With the development of communication technology and the increase of user demand, data services have been developed rapidly, and the rapid growth of data traffic has made people's demand for communication bandwidth increasingly high. Broadband access is showing a huge market to the industry. In order to break through the bandwidth bottleneck of the access network, various broadband access technologies have been introduced. [0003] 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. The IEEE802.16 standard mainly includes three standards: 802.16...
