Abstract:
1. A method for estimating a cell location for a cell that provides wireless communication services to a plurality of mobile stations each mobile station having a Satellite Positioning System (“SPS”) receiver operating in a positioning system, the method comprising: obtaining a mobile station location for each of N mobile stations having a cell identifier that identifies the cell, each mobile station location being determined using the positioning system; and testing the mobile station locations to determine if the mobile stations are clustered by: determining a first estimated cell center location and a cell radius; defining a plurality of circles having respective radii less than the cell radius with respective centers at respectively different locations within the cell; determining if each of the plurality of circles defines an area containing a cluster of mobile station locations based on the number of mobile stations within each of the circles; and calculating a final estimated location of the cell center based on the determined locations of the plurality of circles.
