1. A location awareness mobile device power conservation method, comprising:

  • receiving location information from one or more receivers in a mobile device;

    receiving a signal indicating whether or not the mobile device is in motion from an accelerometer in the mobile device;

    determining a velocity vector from the location information received;

    if the velocity vector indicates that the mobile device is not in motion, enabling scanning operations for the one or more receivers to be halted to conserve battery power for the mobile device while the mobile device is stationary; and

    enabling scanning operations for the one or more receivers to resume when an indication that the mobile device is moving again is received from the accelerometer; and

    repeating the process until the mobile device is placed in an off position.
