Method and device for determining defective cells

Abstract

An embodiment of the invention discloses a method and device for determining defective cells. The method comprises the steps of: dividing neighboring cells into capacity sharing type neighboring cellsand interference contribution type neighboring cells according to a distance between a preset cell and the neighboring cells of the preset cell as well as frequency to be allocated; and identifying afirst defective cell affecting communication quality in the capacity sharing type neighboring cells by adopting a first identification rule, and identifying a second defective cell affecting communication quality in the interference contribution type neighboring cells by adopting a second identification rule. The method combines the signal coverage factors affecting the communication quality, divides the neighboring cells into the capacity sharing type neighboring cells which are close to the preset cell and free from the same-frequency interference problem and the interference contribution type neighboring cells having the same-frequency interference problem, identifies the defective cells of the neighboring cells of all types by adopting different methods, and improves the identification precision of the defective cells.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for determining a problematic cell. Background technique [0002] The mobile cellular communication system adopts the networking mode of frequency multiplexing, and the same-frequency interference of adjacent cells is one of the main factors of network interference. Therefore, whether it is GSM (Global System for Mobile Communication, Global System for Mobile Communication), CDMA (Code Division Multiple Access, Code Division Multiple Access) or LTE (Long Term Evolution, long-term evolution), it is necessary to control the same frequency of adjacent cells. interference and improve network quality. [0003] Although there are many methods for evaluating the network structure and reducing interference, these methods cannot distinguish the types of cells, and the positioning of problem cells is not accurate enough. Therefore, it is impossible to op...

AI Technical Summary

Problems solved by technology

Although this method evaluates whether the network structure layout is reasonable according to the network health parameters, it cannot distinguish the same-channel interference caused by improper frequency configuration, so as to realize the precise positioning of the problem cell

[0006] To sum up, in the process of realizing the embodiment of the present invention, the inventor found that the existing method for evaluating the network structure and reducing interference uses a certain judgment rule to judge the neighboring cells of the preset serving cell and identify For the problem cell, this method does not consider the signal coverage factors that affect the communication quality, so it is impossible to distinguish the types of neighboring cells, and identify problem cells for different types, resulting in inaccurate identification of problem cells
