A method for releasing a trunking service triggered by a terminal handover cell

Abstract

The invention provides a method for releasing a cluster service triggered by a terminal handover cell, and relates to the technical field of communications. The method comprises the following steps: receiving a handover request response message sent by a target base station handed over by a terminal by a Mobility Management Entity (MME) according to a handover request message; judging whether a cluster bearer exists in a bearer establishment failure list carried in the handover request response message by the MME; and if yes, sending a cluster bearer release indication message to a Trunking Control Function TCF by the MME, so that the TCF releases an ongoing cluster service of the terminal according to the cluster bearer release indication message. According to the method for releasing thecluster service triggered by the terminal handover cell provided by the invention, after the terminal is handed over, a user can immediately perceive that the cluster service is released by a networkside, and the user can re-initiate the cluster service instead of long-time service waiting, which can significantly improve the user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular, to a method for releasing a trunking service triggered by a terminal handover cell. Background technique [0002] The broadband trunking communication system is developed to meet the command and dispatch needs of industry users. It is a dedicated wireless communication system for specific industry applications. It provides command and dispatch functions to users with higher speed and larger bandwidth. It is a multi-purpose and efficient capable wireless communication system. In recent years, broadband trunking systems have been widely used in government departments, public security, emergency communications, electric power, civil aviation, petrochemical and military fields. [0003] B-TrunC (LTE based Broadband Trunking Communication, broadband trunking communication based on LTE technology) broadband trunking communication system takes TD-LTE as the core techno...

Problems solved by technology

After the switching process is completed, the MME will trigger the deactivation of the bearers in the list, and will not notify the TCF (Trunking Control Function, trunking control function) of the abnormal occurrence, resulting in the trunking business still continuing, but the service channel is released, and the user cannot Hearing voice and seeing video, the user experience is poor
