A processing method, device, and base station for performing cell handover on clustered terminals

Abstract

The embodiment of the present invention discloses a processing method, device, and base station for cell handover of clustered terminals. In the method, the cell handover of the terminal is realized through interaction among the terminal, the base station, and the core network of the cluster. When the terminal detects that the signal in the first cell is poor and the signal in the second cell is good, it sends a handover request to the first base station to the second cell, and the first base station sends the request to the cluster core network. The cluster core network first checks whether the second cell is in the scheduling area of ​​the group call, and if not, sends the generated extension field to the second base station, and the second base station does not allocate resources after receiving the extension field, avoiding Misuse of the communication resources of the second cell is avoided. The method ensures that the group call service established in the second cell will not be deleted again, simplifies the process of creating the group call service, improves efficiency, and reduces error probability.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of cluster communication and cell handover, and in particular, to a processing method and device for performing cell handover on cluster terminals, and a base station. Background technique [0002] B-TrunC (broadband trunking communication system) takes TD-LTE as the core technology, and integrates the high speed and large bandwidth of TD-LTE with the characteristics of resource sharing, fast call establishment, and command and dispatch in digital trunking technology. A communication system capable of providing high-speed data transmission. [0003] The group call service is the most basic service provided by the broadband trunking communication system. A group call is a one-to-many half-duplex scheduling call, that is, "one call, one hundred responses". First, the calling user initiates a group call and establishes a group call. Users in the group can apply for speaking through th...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is how to solve the existing method of cell switching for terminals in group calls, which is to perform cell switching first, and then judge whether the switched cell belongs to the scheduling area. Delete the terminals in the group call in the area, which will easily lead to the wrong occupancy of cell resources, and the handover process is cumbersome and error-prone
