System and method for updating location information of voice-over-internet protocol based devices for E911 service
A system and method for updating physical address location information of a wireless device for E911 services. The updating may include determining that the current geographical coordinate location of the wireless device has moved beyond a predetermined distance from a last recorded geographical coordinate location. A physical address location associated with the current geographical coordinate location may then be updated. The physical address location may be updated in the wireless device and/or a data repository operating on a data packet network. The physical address location may be communicated to a public safety answering point (PSAP) in response to an emergency 911 call being placed.
1. A method for updating physical address location information of a wireless device for E-911 services, said method comprising:
storing a physical address location in memory on the wireless device;
determining a current physical address location of a wireless device in communication with a data packet communications network; and
in response to determining that the current physical address location of the wireless device is different from the stored physical address location, updating the physical address location stored in memory on the wireless device with the current physical address location, wherein updating the physical address location comprises:
querying a history of previous physical address locations of the wireless device;
determining if the physical address location of the wireless device is in the history of previous physical address locations of the wireless device;
updating a last recorded physical address location with the current physical address location in response to a determination that the physical address location is in the history of previous physical address locations of the wireless device; and
prompting a user of the wireless device to input the current physical address location in response to determining that the physical address location is not in the history of previous physical address locations of the wireless device.
2. The method according to claim 1 , further comprising:
replacing the last recorded physical address location with the physical address location of the wireless device.
3. The method according to claim 1 , further comprising:
connecting to the data packet communications network; and
querying for the physical address location based on geographic coordinate location in response to determining that the physical address location of the wireless device is not found in the history of previous physical address locations of the wireless device.
4. The method according to claim 1 , further comprising communicating by the wireless device the current physical address location of the wireless device to a public safety answering point (PSAP) in response to a user dialing 911.
5. The method according to claim 4 , wherein the wireless device communicates the physical address location to the PSAP by including the physical address location in a caller ID data packet.
6. A wireless device comprising:
a processing unit configured to:
store a physical address location in memory on the wireless device, wherein the physical address location includes a street address;
determine a current physical address location of the wireless device in communication with a data packet communications network;
update the stored physical address location with the current physical address of the wireless device, in response to determining that the current physical address location of the wireless device is beyond a predetermined distance from the stored physical address location, wherein updating the physical address location comprises:
querying a history of previous physical address locations of the wireless device;
determining if the physical address location of the wireless device is in the history of previous physical address locations stored for the wireless device;
performing a predetermined action in response to determining if the physical address location of the wireless device is in the history of previous physical address locations stored for the device; and
prompting a user of the wireless device to input the current physical address location in response to determining that the physical address location is not in the history of previous physical address locations of the wireless device.
7. The system according to claim 6 , wherein the processing unit, in performing the predetermined action, is further configured to:
update a last recorded physical address location found in the history of previous physical address locations in response to determining that the physical address location of the wireless device is found in the history of previous physical address locations; and
replace the last recorded physical address location with the physical address location of the wireless device.
8. The system according to claim 6 , wherein the predetermined action includes the processing unit connecting to the data packet communications network to query for the physical address location based on geographic coordinate location of the wireless device in response to the determination that the physical address location of the wireless device is not found in the history of previous physical address locations of the wireless device.
9. The system according to claim 6 , wherein the wireless device is a VoIP device.
10. The system according to claim 6 , wherein the physical address location is updated in response to the processing unit determining that the wireless device has moved beyond a predetermined distance of 100 feet.
11. The system according to claim 6 , wherein the processing unit is further configured to communicate the physical address location to a PSAP in response to a user dialing 911.
