Abstract

A method is provided in one example embodiment and includes receiving a dynamic host configuration protocol (DHCP) discovery signal at a wireless network element from a customer premise equipment; requesting that a data session be established at a gateway; receiving an Internet protocol (IP) address; and communicating the IP address to the customer premise equipment.

Claims (47)

1. A method, comprising:

receiving a dynamic host configuration protocol (DHCP) discovery signal at a wireless network element, functioning as a DHCP server, from a customer premise equipment;

receiving a proxy binding update from an access gateway, wherein the proxy binding update was sent in response to receiving the DHCP discovery signal from the customer premise equipment;

communicating a request from the wireless network element that a data session be established at a gateway anchor point, wherein the gateway is a General packet radio service support node (GGSN) or a packet data network gateway (PDN-GW);

receiving at the wireless network element, an Internet protocol (IP) address;

communicating the IP address to the customer premise equipment from the wireless network element;

receiving the IP address and a media access control address (MAC) from the customer premise equipment;

binding the IP address and the MAC address; and

communicating the binded IP address and MAC address to the GGSN or the PDN-GW.

2. The method of claim 1 , further comprising:

establishing a GTP tunnel with the GGSN or the PDN-GW.

3. The method of claim 1 , wherein mobility of the customer premise equipment is managed by a local mobility anchor.

4. The method of claim 1 , wherein a request for establishing the data session is a packet data protocol context.

5. The method of claim 1 , wherein the wireless network element is an extended wireless access gateway service provider.

6. The method of claim 1 , wherein the wireless network element includes Wi-Fi access gateway functions and tunnel termination gateway functions.

7. The method of claim 1 , wherein the wireless network element is configured to operate as a radius proxy for a plurality of customer premise equipment.

8. The method of claim 1 , wherein the wireless network element and the gateway are on the same subnet.

9. The method of claim 1 , wherein the extended wireless access gateway service provider is configured to allow the customer premise equipment to have common service management on a wireless local area network and the GGSN.

10. The method of claim 1 , further comprising:

binding the IP address and the MAC address with a general packet radio service tunneling protocol (GTP) identifier to establish a GTP tunnel with the GGSN or the PDN-GW; and

communicating the binded IP address and MAC address to the GGSN or the PDN-GW.

11. Logic encoded in non-transitory media that includes code for execution and when executed by a processor operable to perform operations, comprising:

receiving a dynamic host configuration protocol (DHCP) discovery signal at a wireless network element from a customer premise equipment, wherein the wireless network element is configured to function as a DHCP server;

receiving a dynamic host configuration protocol (DHCP) discovery signal at a wireless network element, functioning as a DHCP server, from a customer premise equipment;

receiving a proxy binding update from an access gateway, wherein the proxy binding update was sent in response to receiving the DHCP discovery signal from the customer premise equipment;

communicating a request from the wireless network element that a data session be established at a gateway anchor point, wherein the gateway is a General packet radio service support node (GGSN) or a packet data network gateway (PDN-GW);

receiving at the wireless network element, an Internet protocol (IP) address;

communicating the IP address to the customer premise equipment from the wireless network element;

receiving the IP address and a media access control address (MAC) from the customer premise equipment;

binding the IP address and the MAC address; and

communicating the binded IP address and MAC address to the GGSN or the PDN-GW.

12. The logic of claim 11 , the operations further comprising:

establishing a GTP tunnel with the GGSN or the PDN-GW.

13. The logic of claim 11 , wherein mobility of the customer premise equipment is managed by a local mobility anchor.

14. The logic of claim 11 , wherein a request for establishing the data session is a packet data protocol context.

15. A network element, comprising:

a memory element;

a processor operable to execute instructions associated with electronic code; and

an access module that interfaces with the processor such that the network element:

receives a dynamic host configuration protocol (DHCP) discovery signal at a wireless network element, functioning as a DHCP server, from a customer premise equipment;

receives a proxy binding update from an access gateway, wherein the proxy binding update was sent in response to receiving the DHCP discovery signal from the customer premise equipment;

requests a packet data protocol context to obtain an IP address for the customer premise equipment and that a data session be established at a gateway anchor point, wherein the gateway is a General packet radio service support node (GGSN) or a packet data network gateway (PDN-GW);

receives an Internet protocol (IP) address;

communicates the IP address to the customer premise equipment;

receives the IP address and a media access control address (MAC) from the customer premise equipment;

bind the IP address and the MAC address; and

communicate the binded IP address and MAC address to the GGSN or the PDN-GW.
