Abstract
An apparatus and method for conserving power on a mobile device through motion awareness. The method includes a motion model that receives location information from one or more receivers and an accelerometer. The motion model determines whether the mobile device is in motion based on the received information. If the mobile device is in motion, a scanning rate for the one or more receivers is determined based on a velocity vector, the velocity vector being determined from the received information; the determined scanning rate is sent to the one or more receivers to enable them to operate at the determined scanning rate; and the process is repeated. If the mobile device is not in motion, the scanning operations for the one or more receivers are halted while the mobile device is stationary; scanning operations for the one or more receivers are resumed when an indication that the mobile device is moving again is received from the accelerometer; and the process is repeated.
