Problems solved by technology

[0003] At present, LTE cells affected by interference use manual judgment based on experience in the work of locating interference sources. The waveforms presented by the interference level of the same interfered cell often contain several interference sources, which makes network optimization personnel The accuracy and work efficiency of judging the source of interference are greatly limited
At the same time, the existence of interference sources will continuously increase the background noise of interference signals in a large area of ​​the wireless network. Interference problems directly affect user experience, such as intermittent calls, slow Internet access, call failures, and dropped calls, etc., increasing the network construction of operators. with the burden of optimization
[0004] At present, most of the interference location technologies in the mobile communication network optimization industry are manually collecting measurement data, generating interference waveforms through EXCEL macros, and then locating the interference type of the interfered cell through manual judgment. Manually cannot accurately judge the specific interference. The simultaneous influence of several types of interference sources leads to large errors in the positioning of interference types. In the process of troubleshooting, each component of the base station can only be located by taking turns to check, which is time-consuming and laborious.
[0005] For large-scale interference areas, it is necessary to send field testers to conduct on-site frequency scanning through frequency scanners, and continuously climb to high-rise buildings on site to compare the signal strength of surrounding interference sources, and locate interference sources based on signal strength fluctuations. It takes a lot of time, manpower and material resources to find the interfered cell and locate the interference source, and the efficiency of solving the problem is low
