Embodiment Construction
[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0051] The embodiment of the present invention discloses a base station switching method, which is applied to a cluster terminal, and the cluster terminal stores position information of a registrable base station;
[0052] Specifically, the trunking terminal stores location information of registrable base stations, specifically including storing longitude and latitude information of registrable base stations. There are two main ways for the cluster terminal to...

The invention provides a base station switching method and a cluster terminal. The base station switching method is applied to the cluster terminal, the cluster terminal stores position information of registered base stations, and the method comprises the following steps: obtaining the position information of an own position; screening a set number of base stations having the minimum distance from the registered base stations according to the position information of the own position and the stored position information of the registered base stations; forming a target base station group; separately scanning the signal intensity of the base stations in the target base station group to obtain the base station having the highest signal intensity; and registering the scanned base station having the highest signal intensity. In the technical scheme of the invention, before the signal intensity of the base stations is scanned, the base stations having smaller distances are screened from all registered base stations, the base stations not satisfying the signal intensity requirements are filtered, the workload of scanning the signal intensity of the base stations subsequently is reduced, and the base station switching can be accomplished quickly.
Description
technical field [0001] The invention relates to the technical field of trunking communication, in particular to a base station switching method and a trunking terminal. Background technique [0002] The trunking terminal is an important part of the trunking communication system, which is used in emergency communications, public safety, emergency protection, regional deployment and control, police duty and other fields. When the trunking terminal is in an area with weak signal strength such as overlapping coverage areas of multiple base stations, it needs to search for a base station with strong signal strength through background scanning and complete base station switching. [0003] In the prior art, the method for the trunking terminal to perform background scanning and complete base station switching is as follows: the trunking terminal scans the signal strength of the registered base stations sequentially, scans 10 base stations each time, and switches if a base station t...
