Location enabled device with power saving control and method thereof
First Claim
1. A method for saving power for an energy constrained device comprising:
- receiving a device location request for the energy constrained device;
determining by a motion detector whether the energy constrained device has moved; and
determining whether to request position information from a device position determinator based on whether the energy constrained device has moved.

Abstract
An energy constrained device (100) includes a motion sensor (150) operative to detect motion of the device (100); a device position determinator (130); and a controller (110) operatively coupled to the motion sensor (150) and to the device position determinator (130) and operative to receive a device location request for the energy constrained device (100), to determine whether the energy constrained device (100) has moved based on the motion sensor (150), and to determine whether to request position information from the device position determinator (130) based on device movement. A method for saving power for a device position determinator (130) in a energy constrained device (100) includes determining whether position information has been requested from the device position determinator (130); and if not so, automatically switching the device position determinator (130) to a low power consumption mode.
