ABSTRACT:
A method is provided in a communication system for determining a relative position change of a wireless modem. The first location of the wireless modem is determined, and then the wireless modem reports the first location to a service node. A dead reckoning device within the wireless modem then determines a second location of the wireless modem. If the second location is greater than a predetermined distance from the first location, then the wireless modem reports the second location to the service node.
