Method and device for checking direction of antenna feeders of base stations

Abstract

The invention relates to a method and a device for checking the direction of antenna feeders of base stations. The method includes: acquiring call release bill data in each sector of the base stations in a set time period, wherein when calls are released, a user terminal is kept connected with at least three base stations; determining the location of the user terminal when any call in any sector of the base stations is released according to the acquired bill data; fitting a bill direction angle of any sector on the basis of the determined location of the user terminal when all the calls in any one of the sectors are released; determining whether the antenna feeder in each sector of the base stations has connection errors or not and whether a work parameter direction angle of each sector is correct or not according to the relation between the bill direction angle of each sector of the base stations and the work parameter direction angle. By the method and device, the connection problem of the antenna feeders of the base stations can be checked efficiently.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and in particular, to a method and device for checking the direction of an antenna feeder of a base station. Background technique [0002] Faced with the constant construction and adjustment of the CDMA (ode Division Multiple Access, Code Division Multiple Access) base station antenna feeder system, the base station antenna feeder often There are problems such as reverse connection of sectors, mandarin duck connection, or inaccurate direction angle of industrial parameters. [0003] Among them, the reverse connection of sectors includes two kinds of feeder cross-connection and clockwise reverse connection between sectors. For example, the feeder of the first sector is installed on the antenna of the second sector, and the feeder of the second sector is installed on the antenna of the first sector, forming a cross-connection of the feeder between the sectors. For another example, t...

AI Technical Summary

Problems solved by technology

One is based on the drive test data, and obtains the fitting direction angle from the test data with the largest pilot average signal-to-noise ratio in each sector, so as to judge whether the sector is reversed or connected, but this method is still unavoidable A lot of road testing work, time-consuming and laborious

Another method is to comprehensively judge whether the sector connection is reversed based on inter-sector switching information and sector direction information, but this method is only limited to sector connection reversal, and cannot solve problems such as mandarin duck connection or inaccurate direction angle.

[0009] From the above analysis, it can be seen that none of the existing antenna feeder direction inspection methods can efficiently conduct comprehensive inspections on problems such as reversed sector connections, mandarin-duck connections, and inaccurate orientation angles.
