Description

technical field [0001] The present invention belongs to the technical field of communication, and in particular, relates to an interference type identification method, device, equipment and computer-readable storage medium. Background technique [0002] For mobile communication networks, the prerequisite for ensuring service quality is to use clean spectrum, that is, the frequency band is not used or interfered by other systems. Otherwise, the performance of the interfered system and the experience of end users will be greatly negatively affected. [0003] With the gradual construction of 4G LTE base stations, the coexistence of 2 / 3 / 4G base stations has formed, and the probability of inter-system interference has also increased significantly. Among the currently constructed base stations, a large number of TD-LTE base stations have been found to be interfered . These interferences mainly include intermodulation interference and spurious interference from 2 / 3G cells to TD-L...

AI Technical Summary

Problems solved by technology

Usually LTE exceeds -110dBm / PRB and reaches a moderate interference level, which is considered to be interference. At present, in the wireless network optimization work, it is impossible to warn in advance when interference will occur. Generally, after the network indicators are found to deteriorate, the interference is found through the background analysis of the system before interference is performed. Analysis and positioning, this process needs to eliminate the sources of interference one by one, in order to carry out targeted processing

During the investigation process, multiple base stations may be interfered by one source, and there is also the possibility that multiple interferences may occur at the same time in one base station. Therefore, the positioning process is complicated, and various types of interference need to be investigated, resulting in a complicated and time-consuming investigation process. Realize the rapid location of interference sources

In addition, the above-mentioned traditional interference location method also requires high skill and experience of network optimization engineers, and the corresponding labor cost will be high
