Embodiment Construction

[0084] 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.

[0085] In the present invention, the terminal obtains the MBS Authorization Key (MBS AuthorizationKey, referred to as "MAK") and its context from the MBS service network, and obtains the multicast parameters and multicast security key of the MBS service from the bearer network. The obtained information can On the bearer indicated by the multicast parameters successfully, the corresponding MBS service data is received through the MBS service key (MTK) generated by the MBS authorization key and the multicast security key. Among them, the steps for the terminal to obtain from the MBS service network and the steps from the bearer network are not in a fixed order. It can be obtained from the MBS service network first and then from the bearer network, or it can be obtain...

Abstract

The invention relates to the field of communications, which discloses a method for a communications system and a terminal to join a multicast broadcast service, which ensures that the terminal can be smoothly joined MBS business in order to receive the MBS business data. In the invention, the terminal acquires the MBS authorization key from an MBS service network then acquires the MBS multicast parameters and / or a multicast security key from the loading network in order to join the corresponding MBS business. Through the processes, the terminal can successfully receive the corresponding MBS business parameters based on the loading indicated by the multicast parameters, according to MBS security key that is generated by the MBS authorization key and the multicast security key. Before the MBS authorization key is issued, the MBS service network needs to certify the terminal and does not issue the MBS key to the terminal unless the certification is passed. The process that the terminal acquires the MBS multicast parameters and the multicast security key for joining the MBS business, from the loading network can be started either from the side of the network or directly from the terminal.

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] Worldwide Interoperability for Microwave Access (WiMAX for short) is a wireless metropolitan area network access technology based on the IEEE 802.16 series standards in the industry. Its basic goal is to provide a one-to-many Broadband wireless access means that can effectively interoperate in a multi-vendor environment. [0004] Specifically, the 802.16 series of standards stipulate some protocol layers of the air interface of the WiMAX system, mainly including a physical layer (PHY) and a medium access control (Medium Access Control, "MAC") layer.
