Systems and methods for third party emergency call termination
First Claim
Patent Images
1. A method for updating a physical location record in a database in connection with servicing a telecommunications call over at least a voice over Internet protocol (VoIP) network, the method comprising:
- receiving a telecommunications call originating from a communication device;
determining whether the communication device is associated with an automatic locating device;
if the communication device is associated with an automatic locating device, then querying for a current set of physical location coordinates generated by the automatic locating device;
receiving the current set of physical location coordinates, wherein the physical location coordinates are imbedded in the session initiation protocol (SIP) message;
comparing the current set of physical location coordinates to a set of physical location coordinates contained in the physical location record; and
if the current set of physical location coordinates are different from contained set of physical location coordinates, updating the physical location record to include the current set of physical location coordinates.

Abstract
Various systems and methods for servicing emergency calls are disclosed. One such method includes providing a location database that includes physical location information about a communication device. This location information can be accessed either directly or indirectly by an emergency service answering system, while concealing the information from a network responsible for terminating the call.

-
receiving a telecommunications call originating from a communication device; determining whether the communication device is associated with an automatic locating device; if the communication device is associated with an automatic locating device, then querying for a current set of physical location coordinates generated by the automatic locating device; receiving the current set of physical location coordinates, wherein the physical location coordinates are imbedded in the session initiation protocol (SIP) message; comparing the current set of physical location coordinates to a set of physical location coordinates contained in the physical location record; and if the current set of physical location coordinates are different from contained set of physical location coordinates, updating the physical location record to include the current set of physical location coordinates. - View Dependent Claims (2, 3, 4)

5. A method for servicing transitory telecommunication calls over at least a voice over Internet protocol (VoIP) network, the method comprising:
-
providing a database having at least one physical location record; receiving a telecommunications call originating from a communication device, wherein the communication device is associated with an automatic locating device; receiving a current set of physical location coordinates generated by the automatic locating device, wherein the physical location coordinates are imbedded in the session initiation protocol (SIP) message; comparing the current set of physical location coordinates to a prior set of physical location coordinates contained in the physical location record; if current set of physical location coordinates are different from the prior set of physical location coordinates, updating physical location record to include the current set of physical location coordinates; and transmitting the current set of physical location coordinates to a third party for use in providing dispatch services. - View Dependent Claims (6, 7, 8)

9. A method for updating a physical location record in a database in connection with servicing a telecommunications call over at least a voice over Internet protocol (VoIP) network, the method comprising:
-
receiving a telecommunications call originating from a communication device; if the communication device is associated with an automatic locating device; receiving a current set of physical location coordinates generated by the automatic locating device, wherein the physical location coordinates are imbedded in the session initiation protocol (SIP) message; comparing the current set of physical location coordinates to a set of physical location coordinates contained in the physical location record; and
if current set of physical location coordinates are different from contained set of physical location coordinates, updating physical location record to include the current set of physical location coordinates;if the communication device is not associated with an automatic locating device; receiving an Internet Protocol (IP) address associated with a device involved in servicing the telecommunications call; comparing the received IP address to a prior IP address associated with prior telecommunications call involving the communication device; if the received IP address does not match the prior IP address, then querying the communication device for a current physical location information; receiving the current physical location information; and registering the current physical location information in association with the communication device in the physical location record. - View Dependent Claims (10, 11, 12, 13, 14)
