Method and device for managing cell coverage

Abstract

The embodiment of the invention provides a management method and device for a cell coverage range, relates to the technical field of wireless communication and can timely discover a cell coverage problem and provide guidance for cell optimization work. The specific scheme comprises the steps of obtaining target data of cells in a preset range; determining reasonable coverage ranges, actual coverage ranges and call drop rates of the cells in the preset range according to the target data of the cells; and dividing description vectors of the cells in the preset range into K clusters through a k-means algorithm, wherein the description vector of one cell comprises the call drop rate and a coverage ratio of the cell, the coverage ratio is the ratio of the actual coverage range and the reasonable coverage range of the cell, and the K clusters at least comprise a normal coverage cluster, an excessive coverage cluster and a weak coverage cluster. The method and the device are used for determining the cells with the coverage problem.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication technologies, and in particular to a method and device for managing cell coverage. Background technique [0002] Cell coverage problems in 3G networks include over-coverage and weak-coverage situations. [0003] Over-coverage refers to the phenomenon that the coverage in the network is too large and far away. Over-coverage means that the signal of the main control sector is too strong, exceeding the reasonable coverage of the sector, resulting in no main pilot in the coverage of other cells or the cross-area signal becomes the main control signal instead of the guest, which brings serious damage to the sector. Interference causes uneven distribution of interference within the network, which in turn causes wireless signal clutter, resulting in poor connection performance, poor call quality, and dropped calls, affecting the quality of service to users.

AI Technical Summary

Problems solved by technology

Weak coverage will cause the main coverage cell to have insufficient control over the coverage area of ​​the main control area, and the planned coverage area cannot be realized

[0005] In the prior art, in order to identify cells with coverage problems, the common practice is to manually read the log (English: LOG) information, combined with drive test data analysis, it is found that there are abnormal events caused by over- or weak coverage of relatively distant cells , these abnormal events are usually quality of service problems that seriously affect user experience, such as poor pilot channel quality index Ec / Io, continuous call drop, low data service download rate, etc.

[0006] However, the problematic cell can only be found through the LOG information after the coverage problem has occurred, and usually only when the problem is more serious, so that the existing technical solutions cannot detect the cell coverage problem early
