1. A method, comprising:
- calculating a plurality of geolocation estimates of a wireless communication device for a plurality of time periods, wherein each geolocation estimate comprises a position estimate and a reliability metric associated with said position estimate, wherein said reliability metric is determined using a number of base stations from which a pilot signal was received during said time period; and
selecting from said plurality of calculated geolocation estimates a most reliable geolocation estimate of said wireless communication device.

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)
