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.

Claims

1. A method for updating a physical location record in a database in connection with servicing a telecommunications call, 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;

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.

2. A method as recited in claim 1, wherein the updating act comprises:

replacing the contained set of physical location coordinates with the current set of physical location coordinates.

3. A method as recited in claim 1, wherein the automatic locating device is a Global Positioning System (“

GPS”

).

4. A method as recited in claim 1, wherein the updating act comprises:

converting the current set of physical location coordinates to address information useful in dispatching emergency personnel.

5. A method for servicing transitory telecommunication calls, 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;

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.

6. A method as recited in claim 5, wherein the automatic locating device is a Global Positioning System (“

GPS”

).

7. A method as recited in claim 5, wherein the updating act comprises:

converting the current set of physical location coordinates to address information useful in dispatching emergency personnel.

8. A method as recited in claim 5, wherein the updating act comprises:

replacing the prior set of physical location coordinates with the current set of physical location coordinates.

9. A method for updating a physical location record in a database in connection with servicing a telecommunications call, 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;

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.

10. A method as recited in claim 9, wherein if the communication device is not associated with an automatic locating device and if the received IP address does not match the prior IP address, the method further comprising:

connecting the communication device to a data collection unit to perform the querying act.

11. A method as recited in claim 9, wherein the automatic locating device is a Global Positioning System (“

GPS”

).

12. A method as recited in claim 9, wherein the updating act comprises:

converting the current set of physical location coordinates to address information useful in dispatching emergency personnel.

13. A method as recited in claim 9, wherein if the communication device is not associated with an automatic locating device and if the received IP address does not match the prior IP address, the registering act comprising:

replacing physical location information contained in the physical location record with the current physical location information.

14. A method as recited in claim 9, wherein if the communication device is associated with an automatic locating device and if the current set of physical location coordinates are different from contained set of physical location coordinates, the updating act comprising:

replacing the contained set of physical location coordinates with the current set of physical location coordinates.
