Abstract:
1. A method for determining the co-location of cell sites in a communication system by a communication device located in a serving cell site, the method comprising the steps of: (a) acquiring a neighbor cell site list at the communication device, the neighbor cell site list identifying neighbor cell sites of the serving cell site; (b) monitoring the neighbor cell sites for latitude and longitude information; (c) calculating the distance and directional bearings between the serving cell site and the neighbor cell sites; (d) grouping together neighbor cell sites having similar bearings and distances from the serving cell site together in the neighbor cell site list, where the similar bearings and distances indicate that the grouped cell sites are sectors of a single base site; and (e) calculating a centroid of a polygon formed by sector vertices of each of the neighbor cell sites that are grouped together in step (d).
