Abstract

An apparatus and method are disclosed for processing a communication request from a roaming VoIP terminal. An apparatus that incorporates teachings of the present disclosure may include, for example, a network proxy having a controller that manages a communications interface in a communication system. The controller can be programmed to receive from a Voice over IP (VoIP) terminal a request to communicate with a destination point, wherein the request comprises an identification (ID) of the destination point, an ID of the VoIP terminal, and a media access control (MAC) address of a gateway providing the VoIP terminal communication access to the network proxy, and determine from the MAC address of the gateway and the ID of the VoIP terminal whether the VoIP terminal is roaming outside of a home network. Additional embodiments are disclosed.

Claims

1. A method comprising:

detecting, by a controller of a gateway, a request from a voice over internet protocol terminal to communicate with an emergency response center;

inserting, by the controller, a media access control address of the gateway into the request based upon detecting the request from the voice over internet protocol terminal to communicate with the emergency response center, the inserting creating a modified request; and

transmitting, by the controller, to a network proxy the modified request with the media access control address of the gateway for enabling communications between the voice over internet protocol terminal and the emergency response center, wherein the gateway remains in a fixed location, wherein a location of the voice over Internet protocol terminal is capable of being determined using a location of the gateway determined from the media access control address of the gateway.

2. The method of claim 1, wherein the gateway comprises a residential gateway.

3. The method of claim 1, wherein the request comprises an identification of the emergency response center and an identification of the voice over internet protocol terminal.

4. The method of claim 1, wherein the media access control address of the gateway and the identification of the voice over internet protocol terminal indicate whether the voice over internet protocol terminal is roaming outside of a home network.

5. The method of claim 1, further comprising:

forwarding, by the controller, to the voice over internet protocol terminal a location request; and

receiving, by the controller, a location of the voice over internet protocol terminal; and

establishing, by the controller, communications between the voice over Internet protocol terminal and the emergency response center and supplying the emergency response center with the location of the voice over internet protocol terminal.

6. The method of claim 5, wherein the location request is directed to an end user of the voice over internet protocol terminal to bring about an exchange of messages with the end user via the voice over internet protocol terminal to determine the location of the end user.

7. The method of claim 6, wherein the messages correspond to at least one of:

voice signals and dual tone multi-frequency signals generated by the end user via the voice over internet protocol terminal.

8. The method of claim 1, wherein the request is transported in a session initiation protocol.

9. A tangible computer-readable medium storing a plurality of instructions which, when executed by a controller of a gateway, cause the controller to perform operations, the operations comprising:

detecting a request from a voice over internet protocol terminal to communicate with an emergency response center;

inserting a media access control address of the gateway into the request based upon detecting the request from the voice over internet protocol terminal to communicate with the emergency response center, the inserting creating a modified request; and

transmitting to a network proxy the modified request with the media access control address of the gateway for enabling communications between the voice over internet protocol terminal and the emergency response center, wherein the gateway remains in a fixed location, wherein a location of the voice over internet protocol terminal is capable of being determined using a location of the gateway determined from the media access control address of the gateway.

10. The tangible computer-readable medium of claim 9, wherein the gateway comprises a residential gateway.

11. The tangible computer-readable medium of claim 9, wherein the request comprises an identification of the emergency response center and an identification of the voice over internet protocol terminal.

12. The tangible computer-readable medium of claim 9, wherein the media access control address of the gateway and the identification of the voice over internet protocol terminal indicate whether the voice over internet protocol terminal is roaming outside of a home network.

13. The tangible computer-readable medium of claim 9, further comprising:

forwarding to the voice over internet protocol terminal a location request; and

receiving a location of the voice over internet protocol terminal; and

establishing communications between the voice over internet protocol terminal and the emergency response center and supplying the emergency response center with the location of the voice over internet protocol terminal.

14. The tangible computer-readable medium of claim 13, wherein the location request is directed to an end user of the voice over internet protocol terminal to bring about an exchange of messages with the end user via the voice over internet protocol terminal to determine the location of the end user.

15. The tangible computer-readable medium of claim 14, wherein the messages correspond to at least one of:

voice signals and dual tone multi-frequency signals generated by the end user via the voice over internet protocol terminal.

16. The tangible computer-readable medium of claim 9, wherein the request is transported in a session initiation protocol.

17. A gateway comprising:

a controller programmed to;

detect a request from a voice over Internet protocol terminal to communicate with an emergency response center;

insert a media access control address of the gateway into the request based upon detecting the request from the voice over internet protocol terminal to communicate with the emergency response center, the inserting creating a modified request; and

transmit to a network proxy the modified request with the media access control address of the gateway for enabling communications between the voice over Internet protocol terminal and the emergency response center, wherein the gateway remains in a fixed location, wherein a location of the voice over Internet protocol terminal is capable of being determined using a location of the gateway determined from the media access control address of the gateway.

18. The gateway of claim 17, wherein the gateway comprises a residential gateway.

19. The gateway of claim 17, wherein the request comprises an identification of the emergency response center and an identification of the voice over internet protocol terminal.

20. The gateway of claim 17, the controller further programmed to:

forward to the voice over internet protocol terminal a location request; and

receive a location of the voice over Internet protocol terminal; and

establish communications between the voice over internet protocol terminal and the emergency response center and supplying the emergency response center with the location of the voice over internet protocol terminal.
