Problems solved by technology

However, the existing solutions rely more on the experience of engineers, and there are often errors in the early interference analysis, which will affect the later interference investigation, resulting in a waste of resources
Moreover, the existing network statistical analysis only analyzes the frequency point data configured by the cell, which restricts the judgment of some types of interference sources.
Although many technical proposals have continuously enhanced the ability of interference analysis, the identification of interference sources has not yet been upgraded to the key element of spectrum analysis.

Abstract

The invention discloses an interference source identification method, which includes: acquiring frequency point scanning data in the frequency band to be analyzed of the cell from the base station side, the frequency point scanning data including idle time data, busy time data and idle burst pulse sequence DummyBurst At least one of the data (S1); analyzing the frequency point scanning data to obtain the power characteristics (S2) exhibited by the analyzed frequency band in at least one period of time; according to the analyzed frequency band in at least one Identify the interference source of the analyzed frequency band according to the power characteristics shown in the time period (S3). The invention also discloses an interference source identification system. The embodiment of the present invention can improve the analysis efficiency of the interference source of the GSM network, effectively locate and solve the interference problem in the GSM network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an interference source identification method and system. Background technique [0002] In communication networks, the identification of various interference sources has always been the focus of network optimization work. In the process of network optimization, it is necessary to identify the type of interference source through a series of index analysis and experience, and link it with the corresponding interference solution. [0003] The current interference troubleshooting solution in the industry mainly uses user complaints and KPI (Key Performance Index, key performance indicators) to analyze whether there is interference in combination with the level value scanned by the uplink frequency point of the problematic cell (only observe the level value). Firstly, use traffic statistics to find cells with high interference bands, and then analyze the sources of inte...
