Abstract

The invention discloses a method and an apparatus for locating an interference source, to improve accuracy and efficiency of location when an interference source of a wireless communication system is located. The method for locating the interference source comprises the steps as follows: selecting at least two adjacent cells from various adjacent cells of a main interference cell requiring location of an interference source as reference interference cells; respectively determining position information of the main interference cell and the at least two reference interference cells; respectively determining indicator of interest (IOI) values of interference signals which are received by the main interference cell and the at least two reference interference cells and are sent by the interference source; and according to the position information of the main interference cell and the at least two reference interference cells as well as the IOI values which are received by the main interference cell and the at least two reference interference cells and sent by the interference source, determining the position information of the interference source.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for locating an interference source. Background technique [0002] At present, when determining an interference source that interferes with a wireless communication system, it is usually determined by manual positioning. For the interfered base station, the testers first go to the top of the base station or the roof to make a preliminary judgment on the direction of interference, that is, the testers use the frequency scanner and directional antenna to scan all-round 360-degree signals, and search for the strongest The direction where the signal is located is identified as the direction of the interference source, and then ground scanning is performed in the direction of the preliminary positioning, and whether the route is judged according to the strength of the signal is correct. The positioning direction is searched until the signal ...
