Abstract

In one embodiment, a method of configuring multiple per user access connections includes receiving, by an access gateway (AG) from an access point (AP), a first extensible authentication protocol (EAP) message including a first capability of a user equipment (UE) and transmitting, by the AG to an authentication, authorization and accounting (AAA) server, a second EAP message including the first capability of the UE and indication second capability of the AG. The method also includes receiving, by the AG from the AAA server, and an AAA message including a negotiated connection capability version and AAA message parameters and transmitting, by AG to the AP, a third EAP message including the negotiated connection capability version.

Claims

1. A method of configuring multiple per user access connections, the method comprising:

receiving, by an access gateway (AG) from an access point (AP), a first extensible authentication protocol (EAP) message comprising a first capability of a user equipment (UE);

transmitting, by the AG to an authentication, authorization and accounting (AAA) server, a second EAP message comprising the first capability of the UE and indication of a second capability of the AG;

receiving, by the AG from the AAA server, and a first AAA message comprising a negotiated connection capability version; and

transmitting, by AG to the AP, a third EAP message comprising the negotiated connection capability version.

2. The method of claim 1, further comprising:

receiving, by the AG from the AP, a fourth EAP message comprising a first access point name (APN) and a second APN; and

transmitting, by the AG to the AAA server, a second AAA message comprising the first APN, the second APN, a first gateway interface, and a second gateway interface.

3. The method of claim 2, wherein the first APN is associated with a first internet protocol (IP) address.

4. The method of claim 2, further comprising:

receiving, by the AG from the AAA server, a third AAA message comprising a first association between the first APN and the first gateway interface, a second association between the second APN and the second gateway interface, and AAA message parameters; and

transmitting, by the AG to the AP, a fifth EAP message comprising the first association between the first APN and the first gateway interface, and the second association between the second APN and the second gateway interface.

5. The method of claim 4, wherein the fourth EAP message is an EAP-Response, the second AAA message is an EAP-Response, the third AAA message is an EAP-Success, and the fifth EAP message is an EAP-Success.

6. The method of claim 4, wherein the second AAA message is a general packet radio service (GPRS) tunneling protocol (GTP) Create Session Request and the third AAA message is a GTP Create Session Response.

7. The method of claim 2, further comprising initiating a release of a first connection between the first APN and the first gateway interface.

8. The method of claim 2, further comprising:

transmitting, by the AG to the AP, a first echo request; and

releasing a first connection between the first APN and the first gateway interface.

9. The method of claim 1, wherein the first EAP message is an EAP-Response, the second EAP message is an EAP-Response, the first AAA message is an EAP-Request, and the third EAP message is an EAP-Request.

10. The method of claim 1, wherein the first EAP message further comprises an identity of the AP, and wherein the second message further comprises the identity of the AP.

11. The method of claim 1, wherein the AG comprises an EAP proxy.

12. A method of configuring multiple per user connections, the method comprising:

transmitting, by a user equipment (UE) to an access point (AP), a first extensible authentication protocol (EAP) message destined for an AG, wherein the first EAP message comprises a first plurality of access point names (APNs);

receiving, by the UE from the AP, a second EAP message comprising an association between the first plurality of APNs and a second plurality of gateway interfaces; and

determining a third plurality of router interface addresses in accordance with the second EAP message.

13. The method of claim 12, further comprising:

transmitting, by the UE to the AP, a third EAP message comprising a capability of the UE; and

receiving, by the UE from the AP, a fourth EAP message comprising a negotiated connection version.

14. The method of claim 13, further comprising receiving, by the UE from the AP, a fifth EAP message comprising an identity of the AP.

15. The method of claim 12, wherein the first EAP message is an EAP request with an access context protocol (ACP), and wherein the second EAP message is an EAP Response ACP.

16. The method of claim 15, further comprising:

transmitting, by the UE to the AP, an EAP Success Message; and

receiving, by the UE from the AP, a Router Advertisement.

17. The method of claim 12, wherein the first EAP message further comprises an IP version.

18. The method of claim 17, wherein the IP version is IP version 4 (IPv4).

19. The method of claim 17, wherein the IP version is IP version 6 (IPv6).

20. The method of claim 12, further comprising:

transmitting, by the UE to the AP, destined for the AG, a first echo request;

transmitting, by the UE to the AP, destined for the AG, a second echo request when the UE does not receive a response from the AP within a first time interval of transmitting the first echo request; and

releasing a connection context when the UE does not receive a response from the AP within a second time interval of transmitting the second echo request.

21. An access gateway (AG) comprising:

a processor; and

a computer readable storage medium storing programming for execution by the processor, the programming including instructions to

receive, from an access point (AP), a first extensible authentication protocol (EAP) message comprising a first capability of a user equipment (UE),

transmit, to an authentication, authorization and accounting (AAA) server, a second EAP message comprising the first capability of the UE and indication second capability of the AG,

receive, from the AAA server, and an AAA message comprising a negotiated connection capability version, and

transmit, to the AP, a third EAP message comprising the negotiated connection capability version.

22. A user equipment (UE) comprising:

a processor; and

a computer readable storage medium storing programming for execution by the processor, the programming including instructions to

transmit, to an access point (AP), a first extensible authentication protocol (EAP) message destined for an AG, wherein the first EAP message comprises a first plurality of access point names (APNs),

receive, from the AP, a second EAP message comprising an association between the first plurality of APNs and a second plurality of gateway interfaces, and

determine a third plurality of router interface addresses in accordance with the second EAP message.
