A method, device and system for interference collection and identification

The present invention provides a method, a device and a system for collecting and identifying interference, applied to a wireless communications network that includes a wireless management device and at least two access point devices. The method includes: requesting each access point device to collect spectrum information, so as to determine interference sources of spectrum information that belongs to a same interference type and is collected by the at least two access point devices, and extracting, from the spectrum information collected by the at least two access point devices, the spectrum information that belongs to the same interference type; matching characteristic sequences of the interference sources, and calculating an overlapping characteristic match value so as to determine whether the match value is greater than a preset threshold, and if the match value is greater than the preset threshold, determining that the extracted spectrum information is from a same interference source, and if the match value is not greater than the preset threshold, determining that the extracted spectrum information is from different interference sources. In the method, the device, and the system for collecting and identifying interference provided in the present invention, a manner of matching overlapping characteristics is used, which has high accuracy in identifying an interference source, and the solution is simple and easy to implement.
