Management method of group call control rights in TD-LTE broadband trunking communication system

Abstract

The present invention provides a management method for group call control rights in a TD-LTE broadband trunking communication system. The management priority of group members is set in a group, and agroup call control rights priority queue constituted by a plurality of intra-group members; dynamic management of the group call control rights is realized based on the intra-group terminal user priority; the dynamic management comprises dynamic monitoring of the current group call control rights conditions and dynamic control of the group call control right authorization; the state of the group call control rights is dynamically detected, and different dynamic control methods are adopted to complete management of the group call control rights according to the difference of the states of the group call control rights. The method can flexibly cope with the loss situation of the group call control rights caused by various emergency situations, so as to effectively avoid the situation that the occupied radio resources and network resources cannot be recovered due to the group call control rights loss, and also shorten the interval time for re-authorization of the control rights, and avoiding serious system load and a decline in terminal user business experience caused by the fact that the group call cannot be released for a long time.

Description

technical field [0001] The invention relates to a method for managing group call control rights in a TD-LTE broadband trunking communication system. Background technique [0002] With the development of wireless communication technology, trunking communication system, as a flexible and efficient command and dispatch communication system developed in recent years, is widely used in government agencies, airport terminals, fire police, industrial and mining enterprises and other fields. The so-called trunking communication system means that the available channels of the system can be shared by all users of the system. The trunking communication system is a multi-purpose, high-efficiency wireless dispatching communication system that shares resources, shares costs, and shares channel equipment and services. [0003] At present, due to the development of TD-LTE technology, the industry has proposed a broadband trunking communication (B-TrunC, Broadband Trunking Communication) sy...

AI Technical Summary

Problems solved by technology

[0009] In view of the defects of the above group call control right management method, the present invention proposes a priority-based dynamic group call control right management method, which can quickly and effectively realize the monitoring and authorization control of the group call control right, and effectively improve the system's ability to control group calls. The ability to manage and control business and system resources solves the problem in the existing technology that group calls cannot be released for a long time, and end users will always be in the state of answering group calls and cannot perform other services. The problem that resources and network resources cannot be recycled and reused
