Problems solved by technology

If the average interference entropy is less than the preset average interference entropy threshold, it indicates that the performance of the wireless network is good, and the coverage of the serving cell is reasonable; on the contrary, if the average interference entropy is greater than the preset average interference entropy threshold, it indicates that the performance of the wireless network is poor , the coverage of the serving cell is unreasonable
[0004] However, in the existing technical solutions, the service cell where the mobile phone resides is taken as the coverage evaluation object, and the evaluation method is affected by the mobile phone and the service cell where the mobile phone resides. There will be deviations in the evaluation of wireless network coverage, and the evaluation accuracy is not enough

Abstract

The embodiment of the invention provides a coverage evaluation method and device. The method comprises the following steps: determining a grid to which each sampling point belongs in a plurality of pre-divided grids corresponding to a target area; for each grid, determining a main signal cell and an auxiliary signal cell of the grid according to the signal intensity of the serving cell and the interference neighbor cell of each sampling point in the grid; and for each grid, evaluating the coverage attribute of the grid according to the signal intensity of the main signal cell and the number ofthe auxiliary signal cells of the grid. According to the scheme provided by the embodiment of the invention, the coverage attribute in the overlapping coverage area can be evaluated, and the evaluation accuracy is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a coverage evaluation method and device. Background technique [0002] LTE (Long Term Evolution, long-term evolution) network generally adopts the same frequency network, how to evaluate whether the network coverage is reasonable, whether the overlapping degree of coverage is appropriate, and locate the problematic cells that cause unreasonable coverage, has always been a network optimization problem. [0003] There is currently provided a solution for evaluating wireless network performance using MR (Measurement Report, measurement report) data, which mainly calculates the overlapping coverage index of the serving cell through the MR level difference between the serving cell and the neighboring cell; then, according to the overlapping The coverage index and the carrier frequency of the serving cell are used to calculate the cell average inter...
