the dividing module is used for acquiring the position of each effective sampling point, dividing the coverage area of the target cell, and determining the coverage area to which each effective sampling point belongs according to the position of each effective sampling point, wherein the coverage area comprises a back coverage area, an over-wide coverage area, an over-far coverage area and a reasonable coverage area;
and the second determining module is used for determining whether the target cell is a problem source cell causing overlapping coverage according to the proportion of the number of the effective sampling points in each coverage area to the total number of all the effective sampling points.
9. An electronic device, comprising:
at least one processor, at least one memory, and a data bus; wherein:
the processor and the memory complete mutual communication through the data bus; the memory stores program instructions executable by the processor, the processor calling the program instructions to perform the method of any of claims 1 to 7.
10. A non-transitory computer-readable storage medium storing a computer program that causes a computer to perform the method according to any one of claims 1 to 7.
