Method and device for switching base station by terminal in narrowband cluster system

Abstract

The invention relates to a method and a device for switching a base station by a terminal in a narrowband cluster system. The narrowband cluster system comprises a handheld terminal and a vehicle-mounted station, the handheld terminal and the vehicle-mounted station are connected to a base station, and when the handheld terminal or the vehicle-mounted station reaches a cross-region threshold, thebase station meeting the condition is not scanned for registration; the handheld terminal or the vehicle-mounted station sends a base station registration request to the narrowband cluster system, wherein the base station registration request comprises position information and auxiliary registration information; the narrowband cluster system issues a registration control channel number to the handheld terminal or the vehicle-mounted station according to the registration base station request; and the handheld terminal or the vehicle-mounted station initiates registration to the base station appointed by the registration control channel number. Through the implementation of the invention, the terminal can accurately register the base station with a better signal, and the terminal is prevented from being unlocked.

Description

technical field [0001] The present invention relates to the field of narrowband trunking systems, and more specifically, relates to a method and device for a terminal to switch base stations under a narrowband trunking system. Background technique [0002] During the use of the trunking system, due to location changes, the base station signal received by the terminal will deteriorate, thereby affecting the call quality. Therefore, when the base station signal satisfies the background scanning or handover start conditions set by the terminal, the terminal will scan the list of neighboring stations, automatically search and register to a base station with better signal quality. Base station switching needs to meet the following conditions: [0003] Condition 1: The current field strength is lower than the scan start threshold; [0004] Condition 2: First scan the neighboring stations, if all the neighboring stations do not meet the switching conditions, start the control cha...

Problems solved by technology

[0006] The main disadvantage of the existing technology: Generally, the parameter settings of the vehicle-mounted station and the handheld terminal are the same. Due to the inconsistency in the power of the cluster handheld terminal, the vehicle-mounted station, and the installation environment of the antenna, the handheld terminal at the same location can meet the conditions for switching to the adjacent station. The vehicle-mounted station It does not meet the handover conditions, so that when the vehicle-mounted station meets the handover threshold, the current base station may not be the neighbor station set by the system, and there is a situation of re-scan registration
