Abstract

The embodiment of the present invention provides a group call channel allocation method and device for voice group call service, by assigning a dedicated channel TCH to the group call originating terminal of this group; Allocate group call channel TCH: In the cell where the group call called terminal to be allocated channel resources is located, determine whether there is available channel resource; if there is, allocate group call channel TCH for the group call called terminal; if not, then In this cell, the target channel that can be preempted is determined according to the preset rules. The preset rules include: using the dedicated channel TCH as the target channel that cannot be preempted; resources, the target channel assigned to the group call terminal to be allocated channel resources in this group cannot be the dedicated channel TCH occupied by the group call originating terminal in this group, which ensures that the voice group call service in this group can be successfully established and ensures The service quality of voice group call service improves user experience.

Description

technical field [0001] The invention relates to the communication field, in particular to a group call channel allocation method and device for a voice group call service. Background technique [0002] Voice Group Call Service (Voice Group Call Service, VGCS) is a point-to-multipoint voice communication mode in which multiple parties participate, some of whom can speak and multiple parties listen. It breaks through the limitations of point-to-point communication, and can establish group calls in a simple and fast way, and realize specific functions such as dispatching command and emergency notification. In the process of voice group call service initiation, a standard two-way channel, that is, a dedicated channel TCH (TrafficChannel, traffic channel), is first provided to the group call originating terminal and the dispatcher, and then a single downlink channel is allocated to all group call called terminals. channel, that is, the group call channel TCH. When channel resou...
