System and method for updating location information of voice-over-internet protocol based devices for E911 services

摘要

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.

主权项

1. A method for updating physical address location information of a wireless device for E-911 services, said method comprising:
determining a current geographic coordinate location of a wireless device in communication with a data packet communications network; and in response to determining that the current geographic coordinate location of the wireless device has moved beyond 100 feet from a last recorded geographic coordinate location, determining a physical address location associated with the current geographic coordinate location by receiving current physical address location from user input or from a networked database; storing a record on the wireless device to associate the current physical address location with the current geographic coordinate location.
