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

Embodiment Construction
[0024] The basic idea of the present invention is: select weak coverage grids according to the MR of all sampling points; select coverage hole grids from the weak coverage grids, and determine the position of the coverage hole grids.
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] The method for locating coverage holes proposed by the present invention, such as figure 1 shown, including the following steps:
[0027] Step 101: Select weakly covered grids according to the MR of all sampling points.
[0028] Specifically, use all the currently acquired MRs to determine the position coordinates corresponding to each sampling point, and divide each sampling point into a corresponding grid area according to the position coordinates corresponding to each sampling point; extract the grid area one by one as the current grid area , use the MR corresponding to all the sampling po...

The invention discloses a method for locating coverage holes, comprising: selecting weak coverage grids according to measurement reports (MR) of all sampling points; selecting coverage hole grids from the weak coverage grids, and determining the coverage hole grids grid position. The invention also discloses a device for positioning and covering the cavity at the same time. By adopting the invention, manual operation can be avoided, thereby ensuring the efficiency and accuracy of positioning and covering the cavity.
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...
