Method and device for detecting overshooting of wireless network

Abstract

The invention provides a method and a device for detecting overshooting of a wireless network. The method comprises the following steps of: obtaining the signal intensity of each cell in each grid, wherein the grids are obtained by dividing the coverage area of the wireless network according to the geographical position; calculating an interference factor of a source cell to a target cell according to the signal intensity; calculating an overshooting factor of the source cell according to the interference factor; and judging the source cell of which the overshooting factor is greater than a first threshold as an overshooting cell. Through the method and device, the signal mutual-interference factors among the cells are sufficiently considered, and the accidental factors of overshooting in the test data are filtered through grid division so that the overshooting problem is located more accurately.

Description

technical field [0001] The present invention relates to the technical field of RF (Radio Frequency, radio frequency) optimization of wireless networks, in particular to a method and device for detecting wireless network over-coverage. Background technique [0002] Over-coverage refers to over-coverage, which means that the signal of a cell appears in an area outside the plan, and the entire area is quite far away from the signal source, even passing several cells. In the GSM network, in order to ensure the continuity of calls of mobile users, there will be a certain range of overlapping areas in the coverage of adjacent base station cells. Key indicators such as sharing ratio and mutual interference area. 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 co...

Problems solved by technology

[0006] However, in the over-coverage location 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 the over-coverage positioning problem
