Mobile phone enhanced cell coverage determining method and system for same
First Claim
1. A method for determining an enhanced cell coverage in a mobile communication system having a plurality of mobile terminals, a plurality of base stations each including at least one antenna, and a cell database containing the relationship between a plurality of cells, the plurality of base stations, and the antennas, the mobile communication system having a communication system coverage for receiving signals and each of the antennas having an antenna coverage for receiving signals, wherein the communication system coverage is divided into a plurality of unit sections, the method comprising the steps of:
- (1.1) designating each one of the plurality of unit sections to be associated with an antenna of one of said plurality of base stations for each of the antennas, said designation being responsive to the shortest distance from a unit section to an antenna, said shortest distance being determined in comparison with the distance from a unit section to all the other antennas in the communication system; and
(1.2) forming a plurality of enhanced cell coverages of said antenna of said base station, wherein said plurality of enhanced cell coverages includes all of the plurality of said designated unit sections for all of the antennas in the communication system.

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.
