ABSTRACT:
A network cellular communication system with power based locator system in which the location of a mobile communication unit within the network can be determined approximately. In particular, the power based locator system includes a pre-stored map of locations of a plurality of base stations within the network and the respective network cell coverage areas for those base stations. Each of the plurality of base stations is able to change the size of its respective cell by varying transmitter and receiver power levels. By incrementally changing its respective cell coverage area, the base station can effectively narrow down the region in which a mobile communication unit is located. The region information is correlated with the pre-stored map of locations to determine approximately where in the cellular communication network the mobile communication unit is located.
