Method and system for updating physical location information
A method and system for updating physical location data associated with a VoIP endpoint device is implemented in a variety of embodiments. In one such embodiment, a VoIP endpoint device stores an identifier for a packet-communicating device which is subject to changing. The VoIP endpoint device has an interface for communication over the Internet via the packet-communicating device and uses a circuit-implemented method for prompting a VoIP user to update physical location data associated with the VoIP endpoint device. In response to a power state transition and a change in the stored identifier, the VoIP endpoint device facilitates an update to the physical location data associated with the VoIP service.
1. A system involving communications between Voice over Internet Protocol (VoIP) endpoint devices and a VoIP server, comprising:
processing circuitry configured and arranged to:
detect a wireless communication connectivity-state transition for a VoIP endpoint device among the VoIP endpoint devices, and output a determination whether a physical location update is appropriate by:
comparing a first stored identifier and a second stored identifier, corresponding to a packet-based communication device through which the VoIP endpoint device communicated before the detected wireless communication connectivity-state transition and after the detected wireless communication connectivity-state transition, respectively; and
altering an indicator on the VoIP endpoint device signifying that a physical location update is not appropriate, in response to the comparison indicating that the first stored identifier and the second stored identifier match.
2. The system of claim 1 , wherein the identifiers for each of the packet-based communication devices are determined based on an address of the packet-based communication device.
3. The system of claim 2 , wherein the processing circuitry is configured and arranged to output a determination whether a physical location update is appropriate by:
determining that an address of the packet-based communication device before the detected wireless communication connectivity-state transition and an address of the packet-based communication device after the detected wireless communication connectivity-state transition are the same; and
outputting to the VoIP server, the determination that the VoIP endpoint device has not changed physical locations and a physical location update is not appropriate.
4. The system of claim 2 , wherein the processing circuitry is configured and arranged to output a determination whether a physical location update is appropriate by:
determining that an address of the packet-based communication device before the detected wireless communication connectivity-state transition and an address of the packet-based communication device after the detected wireless communication connectivity-state transition are not the same; and
outputting to the VoIP server, the determination that the VoIP endpoint device has changed physical locations and a physical location update is appropriate.
5. The system of claim 1 , wherein the identifiers for each of the packet-based communication devices are determined based on a media access control (MAC) address, and wherein the processing circuitry is configured and arranged to output a determination whether a physical location update is appropriate by:
determining a first MAC address associated with the packet-based communication device before the detected wireless communication connectivity-state transition; and
determining a second MAC address associated the packet-based communication device after the detected wireless communication connectivity-state transition.
6. The system of claim 5 , wherein the processing circuitry is further configured and arranged to output a determination whether a physical location update is appropriate by determining that the first MAC address and the second MAC address do not match.
7. The system of claim 1 , wherein the identifiers for each of the packet-based communication devices are determined based on a wide area network (WAN) address, and wherein the processing circuitry is configured and arranged to output a determination whether a physical location update is appropriate by:
determining a first WAN address associated with the packet-based communication device before the detected wireless communication connectivity-state transition; and
determining a second WAN address associated the packet-based communication device after the detected wireless communication connectivity-state transition.
8. The system of claim 7 , wherein the processing circuitry is further configured and arranged to output a determination whether a physical location update is appropriate by determining that the first WAN address and the second WAN address do not match.
9. The system of claim 2 , wherein the identifiers for each of the packet-based communication devices are determined based on at least one of a media access control (MAC) address, an interne protocol (IP) address; and a wide area network (WAN) address.
10. The system of claim 2 , wherein the identifiers for each of the packet-based communication devices are determined based on a combination of a media access control (MAC) address, and a wide area network (WAN) address.
11. The system of claim 2 , wherein the processing circuitry is configured and arranged to determine that the VoIP endpoint device has changed physical location in response to the comparison indicating a portion of the second stored identifier does not match a portion of the first stored identifier.
