Group calling releasing method in group system

Abstract

The invention provides a group calling releasing method in a group system. The method comprises the following steps that: abnormality of a group calling link can be monitored by user equipment (UE) according to data quantity on the current group calling link; and when abnormality of the current group calling link is monitored, a corresponding group calling resource releasing process can be triggered by the UE according to identity information and language permission information in the current group calling, and when the abnormality of a mobile terminal link happens, the group service resource of a user is effectively released.

Description

Technical field [0001] The present invention relates to cluster technology, and in particular to a group call release method in a cluster system. Background technique [0002] The broadband trunking communication system is a communication system that can provide high-speed data transmission rates. The system provides basic trunking call services (group call, single call, broadcast call, etc.) while also providing rich and high-quality broadband multimedia services. Such as real-time video transmission, visual group calling, multimedia broadcasting, high-speed Internet access, etc., to provide real-time and fast command and dispatch service system for industry applications. [0003] The implementation process of the group call service in the broadband trunking communication system is: the user who initiates the group call is the calling user, and other users who access the group call are the called users. All group call users can monitor, and if the user needs to speak, apply The r...

Problems solved by technology

However, in practical applications, due to the complexity of the wireless network environment, the group call link on the user terminal (UE) side may be abnormal.

For example, when a user with a group call enters a non-trunk service coverage area, if the group call is released at this time, the user will not be able to receive the group call release message broadcast by the network side because he is in the non-trunk service coverage area. When the user returns to the trunking service coverage area, the UE will think that the group call that does not exist has always existed because it has not received the group call release message before; another situation is: the user who currently has the group call is in the trunking service coverage area, but due to the poor wireless network environment, the group call release message currently broadcast by the network side has not been received

[0005] It can be seen that the above two cases of UE link abnormality will cause the user's trunking service resources to be still occupied when the group call no longer exists.

However, in the existing trunking system, the same user can only perform one group call service at the same time. In this way, when the trunking service resources of the user are occupied, the user can no longer receive a new group call call. Therefore, the above-mentioned UE link is abnormal The situation will affect the user to receive new group call calls

At present, a method to solve the above problems has not been proposed
