Method and device for positioning and covering hole

Abstract

The invention discloses a method for positioning and covering a hole. The method comprises the steps of selecting out weak covering grids according to a measurement report (MR) of all sampling points; selecting out a grid covering the hole from the weak covering grids; determining the position of the grid covering the hole. The invention further discloses a device for positioning and covering the hole. By means of the method and the device for positioning and covering the hole, manual operation is avoided, and efficiency and accuracy in hole positioning and covering can be ensured.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for locating coverage holes. Background technique [0002] Coverage holes refer to the pilot signal strength in a local area that is too low within the planned coverage area to form continuous coverage, resulting in abnormal events such as access failure, call drop, and handover failure due to weak signals. Currently, there are two methods for locating coverage holes: one is to rely on customer complaints and network drive test information to locate coverage holes; the other is to use key performance indicators (KPI, Key Performance Indicator) to conduct comprehensive analysis and locate coverage holes at the cell level . [0003] However, in the above-mentioned method of locating coverage holes relying on customer complaints and network-wide drive test information, due to the limited number of sampling points of customer complaints or network-wide drive t...

Problems solved by technology

[0003] However, in the above-mentioned method of locating coverage holes relying on customer complaints and network-wide drive test information, due to the limited number of sampling points of customer complaints or network-wide drive test and regional limitations, it is not widely representative and cannot be comprehensive. The coverage of the reaction network; and, the cost is high and the manpower input is large

For the above-mentioned method of comprehensively analyzing and locating coverage holes by using KPIs, although to a certain extent it can solve problems such as lag in finding problems, few sampling points, limited analysis area, and insufficient comprehensiveness in finding problems, etc., the statistics of network management data are based on the unit of a cell , and the coverage of the cell is wider, about 0.6 to 1.6KM, and the coverage is wider in the suburbs or rural areas, so some weak coverage sampling points will be neutralized by a large number of normal sampling points and cannot be found due to the large number of sampling points However, for the cells with coverage problems found by network management data analysis, it is difficult to accurately locate the location of the coverage hole due to the wide coverage of the cell

[0004] It can be seen that the methods for locating coverage holes in the prior art are either slow and require a lot of manpower, or are not accurate enough
