Method and device for detecting installation problems of antenna feeders in base station

Abstract

The invention relates to a method and a device for detecting installation problems of antenna feeders in a base station. The method includes: extracting and calculating N RSSI (received signal strength indicator) averages from the base station; rejecting invalid data in the RSSI averages; calculating an absolute value of a slope difference of the RSSI averages of any two feeders in any sector of the base station at any equal time intervals; determining count values of any two feeders in any vector according to the absolute value of the slope difference and symbols of the RSSI averages of any two feeders in any vector of the base station at any equal time intervals; determining relative uniformity of the RSSI averages of any two feeders in any vector according to N count values of any two feeders in any vector; comparing the relative uniformity of the RSSI averages of any two feeders with a set threshold to determine whether each feeder in the base station has connection errors or not. By the method and the device for detecting the installation problems of the antenna feeders in the base station, accuracy and efficiency in judgment of the installation problems are evidently improved.

Description

technical field [0001] The present disclosure relates to the field of mobile communications, and in particular, to a method and device for detecting installation problems of base station antenna feeders. Background technique [0002] The antenna feeder system is the feed-out and feed-in part of the wireless signal of the mobile communication system, and whether its installation is correct or not is very important to the quality of the mobile communication network. In the established mobile communication network, due to the influence of construction level, construction environment, construction technology and damage, etc., the antenna feeder system of the base station may have the following antenna feeder problems. [0003] One is that the main diversity antenna feeder connection between different sectors of the same base station is wrong. Second, for base stations with single-polarized antennas, the coverage of the main diversity antennas in the same sector of the same base...

Problems solved by technology

[0004] The above phenomenon will have a great impact on the uplink and downlink coverage of the base station wireless signal, affecting the wireless network signal quality and network service performance in the coverage area, and then affecting the user experience

[0005] At present, for the above-mentioned antenna feeder problems, the detection methods mainly include "index statistics method", "DT (DRIVER TEST, driving test, usually also called road test) test method" and "physical survey method", etc. application limitations

[0006] The first "indicator statistics method" is to conduct statistical analysis through traffic indicators on the system side, and analyze the existing abnormal traffic indicators to suspect possible problems such as antenna feeder connection reverse. This method has low judgment accuracy. , only preliminary analysis and judgment can be made
