Processing method and device for carrying out cell switching on terminals of cluster, and base station

Abstract

The embodiment of the invention discloses a processing method and device for cell switching of terminals of a cluster and a base station. In the method, cell switching of the terminals is achieved through interaction of the terminals, the base station and a cluster core network. When the terminal detects that the signal of the first cell is poor and the signal of the second cell is good, a switching request for switching to the second cell is sent to the first base station, and the first base station sends the switching request to the cluster core network. And the cluster core network checks whether the second cell is in the scheduling area of the group call or not, if not, the generated extension field is sent to the second base station, and the second base station does not perform resource allocation any more after receiving the extension field, so that mistaken occupation of communication resources of the second cell is avoided. Through the method, the group call service establishedin the second cell is ensured not to be deleted any more, the establishment process of the group call service is simplified, the efficiency is improved, and the error probability is reduced.

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
