Abstract
A user may locate a missing wireless device through a location server storing user-associated location information. A wireless device includes a client location application adapted to determine a current geographic location and transmit location data to a location server, a power source, and a power management application adapted to detect a low power level and instruct the client location application to determine the current geographic location. The wireless device further includes a GPS receiver adapted to receive and decode GPS signals and a personal GPS directory storing location information associated with the subscriber unit.

6. A wireless device comprising:
-
a client location application adapted to determine a current geographic location and transmit associated location data to a location server; a power source; and a power management application comprising program instructions for instructing the wireless device to, detect a power level of the power source below a first threshold, acquire GPS satellite signals until the power level drops below a second threshold, and determine a last geographic position when the power level drops below the second threshold, the last geographic position being determined based on the acquired GPS satellite signals. - View Dependent Claims (7, 8, 9, 10)
