Unicast establishment method and terminal

Abstract

The present invention provides a unicast establishment method and terminal, wherein the method includes: the terminal obtains the signal quality of the serving cell and the signal quality of each neighboring cell; the terminal determines the sum of the signal quality of each neighboring cell and the preset private parameter , greater than or equal to the signal quality of the serving cell, determine whether there is a multicast channel of the listening group of the terminal in at least one neighboring cell in each neighboring cell; if not, the terminal sends a request to the application server to establish a group unicast , so that the application server establishes a unicast for the monitoring group of the terminal according to the request for establishing the group unicast. In this way, unicast can be established in time, preventing the terminal from being reselected to a neighboring cell that has not established the monitoring group of the terminal, and then going to make up a group, resulting in the loss of words or sentences in monitoring.

Description

technical field [0001] The present invention relates to communication technology, in particular to a unicast establishment method and terminal. Background technique [0002] With the development of wireless communication technology, the wireless trunking communication system has been applied to the communication technology. The wireless trunking communication system is a dedicated mobile communication system in which multiple users share a group of wireless channels and use these wireless channels dynamically; in a group of the wireless trunking communication system, there is a speaker user and multiple listening users. In the wireless trunking communication system of the prior art, the listening user in the idle state switches the listening service by reselecting, so that the listening user can enter a neighboring cell. [0003] In the prior art, when the monitoring user performs reselection, the adjacent cell to be switched needs to establish a multicast channel in advanc...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a method for establishing unicast and a terminal, which are used to solve the problem of when the server first starts in the current cell if the group monitored by the terminal is not established in the adjacent cell when the monitoring user needs to switch the adjacent cell in the prior art. The problem of establishing a unicast service becomes a burning problem
