Method and device for locating network activity in cellular communication networks

摘要

A method and a device for optimizing the assignation of network activity of a cellular communications network to land areas in a simple and accurate way. This technique allows representing the activity of a cellular network on a set of tiles in a grid covering a certain land area, instead of representing it associated to antenna cells that might or might not overlap. The activity dispersed and assigned to non-overlapping grid tiles is much simpler and clearer to understand and allows visualizing how the network activity is distributed over the space and how it varies along time allowing therefore an efficient network design and management optimization.

1. A method for assigning network activity of a cellular communications network to land areas of a certain area of interest, said cellular communications network serving a group of cells each one being served by at least one antenna, the method comprising the following steps performed by an electronic device:
a) For each cell of the group of cells, obtaining cell information and information of the cell coverage as a function of the distance from the antenna, where said cell information includes location information of the antenna serving the cell b) Dividing said area of interest into a set of adjacent non intersecting zones called tiles and assigning to each tile a land use factor, being said land use factor a parameter which indicates the portion of the tile area where it is possible to have network activity c) For each cell of the group of cells, defining a cell coverage polygon d) For each cell coverage polygon, defining one or more sub-polygons according to the information of the cell coverage as a function of the distance from the antenna and assigning to each sub-polygon a distance factor being said distance factor a parameter which indicates the portion of the cell activity that it is assigned to each sub-polygon e) Calculating intersection areas between each tile and each cell sub-polygon and weighting each intersection area by the tile land use factor of the correspondent tile, f) For each tile and each cell, determining a dispersion of the network activity of said cell in said tile based on the weighted intersection areas between said tile and the sub-polygons of said cell and the distance factor assigned to each sub-polygon of said cell.
