Method and system confirming optimal service range of base station

The invention discloses a method and system confirming optimal service range of a base station. The method comprises the following steps: acquiring location information of each base station in a pre-arranged area; taking the base stations as base points; generating a Voronoi figure according to the location information of all the base stations, wherein the Voronoi figure is formed by a Voronoi polygon adopting the base stations as generating elements; taking the area where each base station is located in the Voronoi polygon as the optimal service range of the base station in the pre-arranged area. According to the invention, the Voronoi figure is generated according to the location information of the base stations; the optimal service ranges of the base stations are confirmed according to the Voronoi figure; the complex rate of the calculation method is reduced; the calculation period is shortened; the realization cost is reduced.
