Method for controlling selective band repeater, device and selective band repeater

Abstract

The invention provides a method for controlling a selective band repeater, a device and the selective band repeater, belonging to the field of mobile communication. The method for controlling the selective band repeater comprises the following steps: a control device of the selective band repeater scans downlink signals around a base station; the control device of the selective band repeater determines candidate donor base stations according to the acquired scanning information; the control device of the selective band repeater selects a new donor base station from candidate donor base stations according to the strength of the downlink signals of the current donor base station and the strength of the downlink signals of the candidate donor base station. After the signal strength of the current donor base station reduces to a certain threshold value, the device stops amplifying the signals of the current donor base station, and selects a proper base station as a new donor base station for signal amplification according to the strength of the downlink signals of the candidate donor base station. Each embodiment of the invention can realize the use of the selective band repeater in an on-board scene. The technical scheme of the invention can be widely applied to wireless communication systems.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a control method and device for a frequency selection repeater and a frequency selection repeater. Background technique [0002] The wireless repeater technology is a method to enhance the effective coverage of the wireless base station. It increases the effective coverage area of ​​the base station by bidirectionally relaying wireless signals, which can achieve the purpose of expanding the coverage of the wireless network at low cost and optimizing the network. Traditional repeaters include broadband repeaters, frequency-shift repeaters, frequency-selective repeaters, and optical fiber repeaters. Compared with the broadband repeater, the frequency selective repeater has better performance, can improve the quality of the signal, and the interference effect it brings is relatively small. [0003] The working principle of the frequency selection repeater in the prior art is: ac...

AI Technical Summary

Problems solved by technology

Since the working frequency of the frequency-selective repeater in the prior art is configured in advance, it cannot be automatically updated and adjusted. When the repeater is used as a vehicle, the frequency-selective repeater cannot dynamically switch the donor base station in real time. Therefore, the current frequency selection repeater cannot be applied in the vehicle scene
