Method and system for detecting overshooting of wireless network

Abstract

The invention claims a method and system for detecting overshooting of a wireless network. The method comprises the following steps: determining the interference region of an estimated base station cell, wherein the interference region comprises a region which is located in the maximum coverage area of the estimated base station cell and located outside the ideal coverage area of the estimated base station cell; obtaining the data of sampling points in the interference region of the estimated base station cell and each target base station cell in the interference region; calculating interference factors of the estimated base station cell to each target base station cell; counting each interference factor; calculating the total overshooting decision factor of the estimated base station cell; determining the estimated base station cell to be overshooting when the total overshooting decision factor is more than a first threshold. By utilizing the method and system provided by the invention, the interference factors of the signals among cells are fully considered, and the accidental factor of the overshooting in the test data is filtered, thus the determination of overshooting is ensured to be more accurate.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for detecting wireless network over-coverage. Background technique [0002] Over-coverage is one of the more common problems in the process of GSM network optimization. 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. Reasonable coverage overlapping area planning is the key factor for the healthy development of the GSM network, but in the actual network construction process, due to the contradiction between the rapid expansion of the network and the lagging coverage optimization, the coverage in some areas is unreasonable and p...

[0006] However, in the over-coverage positioning method of the prior art, the above-mentioned TA judgment method is inaccurate, and does not take into account the occasional factors of over-coverage and inter-cell signal interference factors, so it is difficult to accurately locate the over-coverage problem; Although the statistical method of over-coverage points takes into account the accidental factors of over-coverage, it still does not take into account the mutual interference of signals between cells, which reduces the scientificity and accuracy of positioning problems
