Method for transmitting group call configuration information, MME, and system for transmitting group call configuration information

Abstract

The present invention provides a method for transmitting group call configuration information, an MME, and a system for transmitting group call configuration information, wherein the method includes steps of receiving, by the MME, a first message sent by a first base station, wherein the first message includes the group call configuration information of the first base station and a target base station list; for each second base station in the target base station list, inserting the group call configuration information of the first base station into the cache linked list of the second base station for caching the group call configuration information; when the number of nodes in the cache linked list reaches a preset value, combining the group call configuration information of all first basestations in the cache linked list to obtain a second message; and sending the second message to the second base station through a S1 port. It can be seen that the group call configuration informationsent from different first base stations to the same second base station is cached first, and then the cached group call configuration information of the plurality of first base stations are combinedand sent to the second base station. Thus, the message forwarding amount of the S1 port is reduced, a signalling loss probability of the S1 port is reduced, and the normal service and performance of the system are guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, MME and system for transmitting group call configuration information. Background technique [0002] Broadband trunking is a dedicated network technology that supports broadband data transmission and multimedia trunking dispatching applications such as voice, data, and video. In the broadband trunking service, when a mobile terminal user listens to a certain group service, it is possible to move from the coverage of the current base station to the coverage of other base stations. If the mobile terminal user does not know the group call configuration information of the other base station in advance, Then, the group service cannot be monitored continuously when switching between base stations. In order to avoid this problem, in the Broadband Trunking Communication (B-TrunC) standard, there is an adjacency relationship between the first base station and the ...

AI Technical Summary

Problems solved by technology

However, in the actual networking, each base station may be configured with dozens of adjacent base stations. When the number of base stations reaches thousands, the group call configuration information that MME needs to forward through the S1 port will reach tens of thousands. Such frequent message forwarding may It will exceed the forwarding capability of the MME, resulting in the loss of signaling on the S1 interface, affecting the normal business and performance of the system
