Title: Method for locating a mobile station

Abstract: A method provides for the detection of the geographic location of a mobile station within a mobile network. The mobile station detects signal characteristics for signals generated by neighboring cells to create a report of signal characteristics corresponding to the location at which the mobile station resides. This report is then compared against the database of signal signatures identifying geographic locations within the cell in which the mobile station is known to be positioned. The signal signatures are then used to detect either an exact match or an approximate match to give position information of the mobile station within the cell.
