A full-band frequency scanning method, device and small base station

Abstract

The invention is applicable to the communication field, and provides a full-frequency band frequency sweeping method, a device and a small base station. The method comprises the following steps of: ascanning frequency point list is generated; the frequency points corresponding to the frequency point numbers in the scanning frequency point list are searched one by one to determine the frequency points existing in the cells, and the candidate frequency points list of the potential cells is obtained; the RSSI measurement, cell accurate search, RSRP measurement and de-broadcast message are carried out on the frequency points in the candidate frequency point list of the potential cell one by one until the processing of all the frequency points in the candidate frequency point list of the potential cell is completed. The invention can reduce the searching number of the accurate searching of the cell, avoid a large amount of time overhead caused by the blind decomposition broadcast message brought by the virtual detecting cell, shorten the searching time, and improve the sweeping frequency speed. And the RSSI value does not need to be measured at each frequency point to reduce the sweeptime overhead. As that existence of a cell is not determined according to the RSSI threshold, the probability of detection leakage is greatly reduced.

Description

technical field [0001] The invention belongs to the field of communications, and in particular relates to a full-band frequency scanning method, device and small base station. Background technique [0002] Small base station (Small Cell) is a general term for low-power wireless access points provided by operators. They can work in licensed spectrum or WiFi access points in operator-level unlicensed spectrum. Small base stations usually The coverage range is from 10 meters to hundreds of meters. The small base station has the characteristics of low power consumption and short coverage, and can be used as a supplement to the coverage blind spot of the macro base station. On the one hand, it can bring users high-speed access to the network experience; on the other hand, it can provide operators with flexible indoor and outdoor deployment, improving Spectrum utilization can reduce the traffic pressure of the macro network. Compared with the simple amplification of signals by r...
