Abstract

The invention relates to a method and a system for inspecting cell identical and adjacent frequency interference, wherein the method comprises the following steps: 1, inputting the data information of network to be inspected, wherein the data information comprises the position information of a base station, azimuthal angle data, relation of cell adjacent areas and assignment data of cell frequency points; 2, determining the hierarchical relationship of the cells, the inspection range of the cells and the counterblow relation of the azimuthal angle between the cells according to the data information; 3, classifying the various interferences according to the relation of the cell adjacent areas and the hierarchical relationship among the cells; and 4, as for each cell, searching the interference sources of the frequency points of the cell in the inspection range of the cell according to the assignment data of the cell frequency points; determining the grade which the various interference sources belong to; and as for each cell frequency point, utilizing an interference inspection model to generate an interference inspection result corresponding to the frequency point according to the grade of the interference source and the hierarchical relationship between the interference source and the cell. The invention can carry out inspection on the network to find out the cell frequency points in which identical and adjacent channel interference possibly exists.

Description

technical field

[0001] The invention relates to the field of mobile communication, in particular to a method and system for checking same-adjacent frequency interference in a cell. Background technique

[0002] Frequency planning and optimization is an important part of mobile communication network construction and optimization. In the GSM (Global System for Mobile Communication, Global System for Mobile Communications) network, each cell needs to be allocated a BCCH channel (Broadcast Control CHannel, broadcast control channel) and multiple TCH channels (Traffic CHannel, traffic channel), and each channel needs Occupy a certain frequency resource. As the number of mobile users grows, the network scale continues to expand, requiring more frequency resources, which are limited. Therefore, it is very important to allocate frequencies reasonably and improve spectrum utilization. The cellular system allows the multiplexing of the same frequency or adjacent frequencies in cells...
