Abstract

The invention provides a method and device for evaluating network coverage interference, wherein the method for evaluating network coverage interference comprises the following steps of: acquiring estimation parameters; performing grid division on a selected region on the basis of geographic information to generate at least one grid; according to the estimation parameter, calculating the number of interference cells in the grid on the basis of grid convergence; and according to the estimation parameter and the number of the interference cells, calculating interference factors in the grid on the basis of the grid convergence. By taking the number of cell-configured carrier frequencies, actual measurement values of drive test data, the number of the interference cells in the region and other parameter values into full consideration, the estimation method of the invention realizes the scientific calculation of the coverage interference condition in the region so as to realize the quantitative evaluation on the coverage interference condition of a wireless network, thus scientific, quantitative and standard guidance is offered to the optimization of regional wireless coverage.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a network coverage interference evaluation method and device in the technical field of RF (Radio Frequency, radio frequency) optimization of wireless networks. Background technique [0002] Coverage problem is a relatively common and very important problem in the process of GSM (Global System for Mobile Communications) network optimization. Reasonable coverage is the basic guarantee for the normal operation of the network. In the GSM network, in order to ensure the continuity of the mobile user's conversation, there will be a certain range of overlapping areas in the coverage between adjacent base stations. The size of the overlapping area of ​​coverage of adjacent cells determines the handover relationship and traffic sharing Key indicators such as ratio and mutual interference area. Reasonable coverage overlapping area planning is a key factor for improv...
