Embodiment Construction

[0035] 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.

[0036] After the MBS server receives the terminal's request to withdraw from MBS or the conditions for terminating the service for the terminal are satisfied, it will modify the terminal's context, stop MBS service charging and stop updating the key for the terminal, so that the terminal actively initiates the request or passively stops When receiving the MBS service, it can exit the MBS service normally and stop the billing of the MBS service.

[0037] There are several possibilities for the terminal to withdraw from the MBS service:

[0038] 1. The terminal voluntarily exits the MBS: It may be because the user no longer wants to receive the MBS in the activated state, which triggers the exit process. The exit process can be initiated by the terminal in the activ...

Abstract

The invention relates to the radio communication field, discloses a method of exiting multi-broadcasting services of a mobile terminal and a multi-broadcasting service to make a mobile terminal in a WiMAX network exit the MBS service normally. In the invention, a MBS server receives a request of exiting the MBS or ends the condition of providing services to the terminal, modifies context of the terminal, stops MBS service charge and notifies a network side key management body to stop updating the key of the terminal. If the terminal is activated, after the MBS server affirms the terminal exiting the MBS service, the MBS server or an anchor gateway notifies the serving gateway to exit the information, the serving gateway notifies the base station of the terminal to modify corresponding user counting of MBS, triggers a flow for bearing adjustment when the user counting satifies the predetermined condition. If the base station bears the MBS service through a PTP mode, after the terminal exits the MBS service, releases the gap resource corresponding to the MBS of the terminal.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to multicast broadcast technology. 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: 802.16a, 802.16RevD and 802.16e. [0004] Worldwide Interoperabilit...
