Method and device for identifying interference in LTE network, equipment and medium

Abstract

The embodiment of the invention provides a method and a device for identifying interference in an LTE network, equipment and a medium. The method comprises the following steps: acquiring telephone traffic data of each cell in a network, and screening out interference cells of which the noise intensity is greater than a preset threshold value in the telephone traffic data; selecting at least threeselected interference cells from the interference cells, wherein the distance between any two selected interference cells is less than or equal to a preset distance; calculating an interference area covering all the selected interference cells according to the coordinates of the selected interference cells; acquiring MR data of all user equipment in the interference area, and defining the user equipment of which the MR data meets a preset condition as an interference point location; calculating the interference coefficient of each interference point position through the MR data of the interference point positions, calculating the coordinates of the interference source according to the interference coefficient of each interference point position and the coordinates of each interference point position, calculating the position of the interference source by collecting the speech system data and the MR data, and achieving interference checking intellectualization.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method, device, equipment and medium for identifying interference in an LTE network. 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. 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. In the base stations that have been built so far, a large number of TD-LTE (4G network ) The base station is interfered. These interferences mainly include blocking, intermodulation and spurious interference from 2 and 3G cells to TD-LTE cells, in addition to other radio e...
