14. A method for optimizing location-based services in a system comprising a test terminal for receiving GPS signals by using a conventional GPS (C-GPS) operation mode or an assisted-GPS (A-GPS) operation mode, a mobile communication network which includes wireless base stations having a preset maximum antenna range (MAR) and a mobile switching center, and a position determination entity for resetting the MAR by interworking with an MAR database storing geolocation information and the MAR of the wireless base stations, the method comprising the steps of:
-
(a) receiving and storing C-GPS geolocation information obtained in the C-GPS operation mode and A-GPS data obtained in the C-GPS operation mode, the C-GPS geolocation information and A-GPS data being transferred from the test terminal; (b) analyzing the C-GPS geolocation information and A-GPS data of each wireless base station to determine an object wireless base station for which MAR optimization is needed, wherein the object wireless base station is located adjacent to or covers at least one measurement point at which over a predetermined number of GPS satellites are observed and included in the C-GPS geolocation information and less than the predetermined number of GPS satellites are observed and included in the A-GPS data; (c) calculating a new MAR by using a MAR optimizing algorithm, wherein the MAR optimizing algorithm sets the maximum distance between the wireless base station and each measurement point as the new MAR; and (d) setting the new MAR as the optimized MAR of the object wireless base station and storing it in the MAR database. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
