Abstract

A system, method and apparatus for supporting enhanced 911 (E911) emergency services, in a data communications network that includes Voice over Internet Protocol (VoIP) telephones. A network system includes a host network communicatively coupled to an E911 database management system, a network access device, and a VoIP telephone communicatively coupled to an input port of the network access device. The network access device is adapted to assign a physical location identifier to an input port, to authenticate the VoIP telephone, wherein the authentication includes receiving a unique device identifier from the VoIP telephone, and to transmit the location identifier and the unique device identifier to the E911 database management system. The E911 database management system is permitted to store the physical location identifier in association with the unique device identifier.

Claims

1. A method comprising:

by a network access device having an input port, detecting a Voice over Internet Protocol (VoIP) telephone coupled to the input port, the network access device comprising a memory for storing a physical location identifier that identifies a physical location of a termination point of the input port;

when the network access device detects the VoIP telephone coupled to the input port, transmitting an automatic report towards an enhanced 911 (E911) database management system (DBMS);

transmitting a unique device identifier of the VoIP telephone towards the E911 DBMS in response to a first query from the E911 DBMS; and

transmitting the physical location identifier towards the E911 DBMS in response to a second query from the E911 DBMS.

2. The method of claim 1, wherein the authenticating includes authenticating the VoIP telephone in accordance with an IEEE 802.1x protocol.

3. The method of claim 1, wherein the authenticating includes receiving a unique device identifier that comprises a telephone number of the VoIP telephone.

4. The method of claim 1, wherein the authenticating includes receiving a unique device identifier that comprises an Internet Protocol (IP) address of the VoIP telephone.

5. The method of claim 1, wherein the authenticating includes receiving a unique device identifier that comprises a media access control (MAC) address of the VoIP telephone.

6. An apparatus comprising:

an input port;

a memory for storing a physical location identifier that identifies a physical location of a termination point of the input port;

a switching fabric configured to route data received via the input port towards to at least one output port of the apparatus; and

control logic adapted to;

detect a Voice over Internet Protocol (VoIP) telephone coupled to the input port;

when the apparatus detects the VoIP telephone coupled to the input port, transmit an automatic report towards an enhanced 911 (E911) database management system (DBMS);

transmit a unique device identifier of the VoIP telephone towards the E911 DBMS in response to a first query from the E911 DBMS; and

transmit the physical location identifier towards the E911 DBMS in response to a second query from the E911 DBMS.

7. The network access device of claim 6, wherein the control logic adapted to authenticate includes control logic adapted to authenticate the VoIP telephone in accordance with an IEEE 802.1x protocol.

8. The network access device of claim 6, wherein the control logic adapted to authenticate includes control logic adapted to receive a unique device identifier that comprises a telephone number of the VoIP telephone.

9. The network access device of claim 6, wherein the control logic adapted to authenticate includes control logic adapted to receive a unique device identifier that comprises an Internet Protocol (IP) address of the VoIP telephone.

10. The network access device of claim 6, wherein the control logic adapted to authenticate includes control logic adapted to receive a unique device identifier that comprises a media access control (MAC) address of the VoIP telephone.

11. An apparatus comprising:

an input port;

a memory for storing a physical location identifier that identifies a physical location of a termination point of the input port;

means for detecting a Voice over Internet Protocol (VoIP) telephone coupled to the input port;

means for, when the apparatus detects the VoIP telephone coupled to the input port, transmitting an automatic report towards to an enhanced 911 (E911) database management system (DBMS);

means for transmitting a unique device identifier of the VoIP telephone towards the E911 DBMS in response to a first query from the E911 DBMS; and

means for transmitting the physical location identifier towards the E911 DBMS in response to a second query from the E911 DBMS.

12. The apparatus of claim 11, wherein the means for authenticating includes means for authenticating the VoIP telephone in accordance with an IEEE 802.1x protocol.

13. The apparatus of claim 11, wherein the means for authenticating includes means for receiving a unique device identifier that comprises a telephone number of the VoIP telephone.

14. The apparatus of claim 11, wherein the means for authenticating includes means for receiving a unique device identifier that comprises an Internet Protocol (IP) address of the VoIP telephone.

15. The apparatus of claim 11, wherein the means for authenticating includes means for receiving a unique device identifier that comprises a media access control (MAC) address of the VoIP telephone.

16. A nontransitory program storage device readable by a machine, embodying a program of instructions executable by the machine to perform a method, the method comprising:

by a network access device having an input port, detecting a Voice over Internet Protocol (VoIP) telephone coupled to the input port, the network access device comprising a memory for storing a physical location identifier that identifies a physical location of a termination point of the input port;

when the network access device detects the VoIP telephone coupled to the input port, transmitting an automatic report towards an enhanced 911 (E911) database management system (DBMS);

transmitting a unique device identifier of the VoIP telephone towards the E911

DBMS in response to a first query from the E911 DBMS; and

transmitting the physical location identifier towards the E911 DBMS in response to a second query from the E911 DBMS.
