  • Patent number: 6853845
    Abstract: This is a method and system for determining an enhanced cell coverage locating a mobile terminal in a cellular mobile communication system. The overall range of the mobile communication system is divided into a plurality of pixels, and then a pixel map including all pixels is constructed. One antenna with a shortest distance to each pixel is set as a serving antenna, and the nearest antenna to a pixel is found. This pixel then belongs to the cell of this antenna, in which the distance therebetween is smallest and all pixels belonging to a cell constitutes a pixel coverage of this cell. A rectangular area is then constructed covering the pixel coverage, and a smallest circle cover this rectangular area is constructed as the enhanced cell coverage of the antenna. Thereby, the system provider may provide require information to the mobile terminal in that coverage.
