Management method of group call control right under td-lte broadband trunking communication system

Abstract

The present invention provides a method for managing group call control rights under a TD-LTE broadband trunking communication system. By setting the management priorities of group members in the group, a group call control right priority queue composed of multiple members in the group is formed; Dynamic management of group call control rights is realized based on the priority of terminal users in the group. Dynamic management includes dynamic monitoring of the current group call control rights status and dynamic control of group call control rights authorization; dynamic detection of the status of group call control rights and Different dynamic control methods are used to complete the management of the group call control right depending on the state of the call control right. This method can flexibly deal with the loss of group call control rights caused by various emergencies, which can effectively avoid the situation that the occupied wireless resources and network resources cannot be recovered due to the loss of group call control rights, and can shorten the time for re-authorization of control rights. Interval time to avoid group calls being unable to be released for a long time, resulting in severe system load and degradation of end user service experience.

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
