Method of terminal to obtain cluster service server address, and device

Abstract

The embodiment of the invention provides a method of a terminal to obtain a cluster service server address, and a device. According to the method, the terminal sends a cluster service registration request to an eMME of a visited place, so that the eMME of the visited place forwards the cluster service registration request to an eHSS to which the terminal belongs, and the eHSS to which the terminalbelongs allocates and delivers a cluster service registration response to the terminal according to the cluster service registration request, so that the terminal obtains an IP address and a port number of a cluster service server; and when the information of the cluster service server changes, the eHSS can send the changed address and the port number of the cluster service server to the terminalin real time. By adoption of the method of the terminal to obtain the cluster service server address, and the device provided by the invention, the terminal directly performs communication of relatedservice with the server after the cluster service registration is successful, and meanwhile the problem of communication failure of the terminal and the server caused by the change of the cluster service server is avoided.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and equipment for a terminal to obtain an address of a cluster service server. Background technique [0002] The Broadband Trunking Communication (B-TrunC, Broadband Trunking Communication) system supports the architecture of local networking and roaming networking. kind of scene. [0003] For the roaming network architecture, it is divided into two types: a unified enhanced Home Subscriber Server (eHSS, Enhanced Home Subscriber Server) and a distributed eHSS. figure 1 It is a structural diagram of unified eHSS for the roaming network architecture of the B-TrunC system, figure 2 It is a structural diagram of the distributed eHSS for the roaming network architecture of the B-TrunC system. see figure 1 with figure 2 , the broadband trunking communication system under the roaming group architecture is mainly composed of broadband trunking termin...

AI Technical Summary

Problems solved by technology

[0004] However, the change of the cluster service server in the existing solution will cause the communication failure of the broadband cluster terminal according to the local configuration, which will affect the user experience of the broadband cluster terminal
