Abstract

The invention provides a core network system, a system and a method for trunking service registration of a trunking terminal. The terminal sends a first trunking registration request which carries a user name and a digest algorithm name to the core network system without sending codes, so that communication safety is improved; the core network system generates and sends a first authentication request to the terminal according to the first trunking registration request, the terminal sends a second trunking registration request to the core network system, the core network system judges whether authentication of the terminal succeeds or not according to the second trunking registration request, and if yes, a second authentication request is generated and sent to enable the terminal to authenticate the core network system according to the second authentication request; after authentication is successful, the core network system receives registration completion information sent by the terminal. The core network system, the system and the method for trunking service registration of the trunking terminal have advantages that multiple users are enabled to use the same terminal for registration and login, bidirectional authentication between the terminal and the core network system is realized, and safety in communication between the terminal and the core network system is improved.

Description

technical field [0001] The present invention relates to the field of broadband trunking communication, and more specifically, to a trunking service registration method, system and core network system of a trunking terminal. Background technique [0002] B-TrunC (Boardband Trunking Communication, Broadband Trunking Communication) is a TD-LTE-based "LTE digital transmission + trunking voice communication" private network broadband trunking system standard developed by the Broadband Trunking (B-TrunC) Industry Alliance. [0003] Currently, B-TrunC broadband trunking terminals only support single-user login. Cluster services between the terminal and the cluster core network, including registration and logout, are implemented by using the extended NAS protocol instead of the traditional SIP protocol. After the terminal passes the LTE authentication and successfully attaches, it starts cluster registration. The extended NAS registration message sent by the terminal carries clust...
