11. A method, comprising:
-
receiving information from a wireless communication device, said information comprising measurements taken by said wireless communication device of detected pilot signals from at least one base station;
determining a time interval in which said wireless communication device continues to take measurements when fewer than three (3) base stations are detected by said wireless communication device;
selecting a most reliable measurement taken by said wireless communication device among the measurements taken by said wireless communication device when fewer than three (3) base stations are detected by said wireless communication device; and
calculating a geolocation estimate of said wireless communication device using said selected most reliable measurement. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
