1. A communication system comprising:
- a service node;
a wireless modem configured to determine a first location of the wireless modem and report the first location of the wireless modem to the service node in response to the wireless modem entering an initial powered on state;
the wireless modem further comprising a dead reckoning device configured to receive power from a battery when the wireless modem enters a powered off state and determine a positional displacement of the wireless modem during transit from the first location while the wireless modem is in the powered off state;
in response to the wireless modem being moved further than a predetermined positional displacement from the first location and entering a subsequent powered on state, the wireless modem is configured to determine a second location of the wireless modem based on the positional displacement and report the second location to the service node;
wherein if the wireless modem successfully reports the second location to the service node, then the wireless modem is configured to enable voice over Internet protocol (VoIP) circuitry of the wireless modem, and wherein if the wireless modem fails to report the second location to the service node, then the wireless modem is configured to disable the VoIP circuitry and prompt a user of the wireless modem for a present location of the wireless modem.

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.

8. A method for determining a relative position change of a wireless modem, the method comprising:
-
in response to the wireless modem entering an initial powered on state, determining a first location of the wireless modem and reporting the first location to a service node; determining a positional displacement of the wireless modem during transit from the first location while the wireless modem is in a powered off state, wherein the positional displacement is determined utilizing a dead reckoning device configured to receive power from a battery when the wireless modem enters the powered off state; in response to the wireless modem being moved further than a predetermined positional displacement from the first location and the wireless modem entering a subsequent powered on state, determining a second location of the wireless modem based on the positional displacement and reporting the second location to the service node; wherein if reporting the second location to the service node is successful, then enabling voice over Internet protocol (VoIP) circuitry of the wireless modem, and wherein if reporting the second location to the service node fails, then disabling the VoIP circuitry and prompting a user of the wireless modem for a present location of the wireless modem. - View Dependent Claims (9, 10, 11, 12, 13, 14)
