Abstract

An example method is provided in one example embodiment and may include receiving an attach trigger for a user equipment (UE) within a trusted access network; configuring a first signaling path for the UE for a first Internet protocol (IP) connection; and configuring a second signaling path for the UE for a second IP connection, wherein the first and second IP connections are associated with different IP version types. The method can include switching traffic for the UE between the first signaling path for the first IP connection and the second signaling path for the second IP connection based on IP version type of the traffic.

Claims

1. A method for a communication network comprising:

receiving an attach trigger for a user equipment (UE) within a trusted access network;

configuring a first signaling path for the UE for a first Internet protocol (IP) connection; and

configuring a second signaling path for the UE for a second IP connection, wherein the first and second IP connections are associated with different IP version types.

2. The method of claim 1, wherein the first IP connection is associated with a first packet data network (PDN) connection for a first access point name (APN) and the second IP connection is associated with a second PDN connection for a second APN.

3. The method of claim 2, wherein the first signaling path or the second signaling path is configured for at least one of:

an IP version 4 (IPv4) packet data network (PDN) connection using an S2a signaling interface; and

an IP version 6 (IPv6) PDN connection using another S2a signaling interface.

4. The method of claim 1, wherein the first IP connection is associated with an IP version 4 (IPv4) non-seamless wireless offload (NSWO) connection within the trusted access network and the second IP connection is associated with an IP version 6 (IPv6) packet data network (PDN) connection via a 3rd Generation Partnership Project (3GPP) network with an IPv6 access point name (APN).

5. The method of claim 1, wherein the first IP connection is associated with an IP version 6 (IPv6) non-seamless wireless offload (NSWO) connection within the trusted access network and the second IP connection is associated with an IP version 4 (IPv4) packet data network (PDN) connection via a 3rd Generation Partnership Project (3GPP) network with an IPv4 access point name (APN).

6. The method of claim 1, further comprising:

configuring a subscriber profile for a subscriber associated with the UE, which identifies the first IP connection and the second IP connection for the subscriber; and

loading the subscriber profile for the subscriber upon receiving the attach trigger for the UE.

7. The method of claim 1, further comprising:

switching traffic for the UE between the first signaling path configured for the first IP connection and the second signaling path configured for the second IP connection based on IP version type of the traffic.

8. One or more non-transitory tangible media encoding logic that include instructions for execution that, when executed by a processor, is operable to perform operations comprising:

receiving an attach trigger for a user equipment (UE) within a trusted access network;

configuring a first signaling path for the UE for a first Internet protocol (IP) connection; and

configuring a second signaling path for the UE for a second IP connection, wherein the first and second IP connections are associated with different IP version types.

9. The media of claim 8, wherein the first IP connection is associated with a first packet data network (PDN) for a first access point name (APN) and the second IP connection is associated with a second PDN for a second APN.

10. The media of claim 8, wherein the first signaling path or the second signaling path is configured for at least one of:

an IP version 4 (IPv4) packet data network (PDN) connection using an S2a signaling interface; and

an IP version 6 (IPv6) PDN connection using another S2a signaling interface.

11. The media of claim 8, wherein the first IP connection is associated with an IP version 4 (IPv4) non-seamless wireless offload (NSWO) connection within the trusted access network and the second IP connection is associated with an IP version 6 (IPv6) packet data network (PDN) connection via a 3rd Generation Partnership Project (3GPP) network with an IPv6 access point name (APN).

12. The media of claim 8, wherein the first IP connection is associated with an IP version 6 (IPv6) non-seamless wireless offload (NSWO) connection within the trusted access network and the second IP connection is associated with an IP version 4 (IPv4) packet data network (PDN) connection via a 3rd Generation Partnership Project (3GPP) network with an IPv4 access point name (APN).

13. The media of claim 8, the operations further comprising:

configuring a subscriber profile for a subscriber associated with the UE, which identifies the first IP connection and the second IP connection for the subscriber; and

loading the subscriber profile for the subscriber upon receiving the attach trigger for the UE.

14. The media of claim 8, the operations further comprising:

switching traffic for the UE between the first signaling path configured for the first IP connection and the second signaling path configured for the second IP connection based on IP version type of the traffic.

15. An apparatus, comprising:

a memory element for storing data; and

a processor that executes instructions associated with the data, wherein the processor and memory element cooperate such that the apparatus is configured for;

receiving an attach trigger for a user equipment (UE) within a trusted access network;

configuring a first signaling path for the UE for a first Internet protocol (IP) connection; and

configuring a second signaling path for the UE for a second IP connection, wherein the first and second IP connections are associated with different IP version types.

16. The apparatus of claim 15, wherein the first IP connection is associated with a first packet data network (PDN) connection for a first access point name (APN) and the second IP connection is associated with a second PDN connection for a second APN.

17. The apparatus of claim 15, wherein the first signaling path or the second signaling path is configured for at least one of:

an IP version 4 (IPv4) packet data network (PDN) connection using an S2a signaling interface; and

an IP version 6 (IPv6) PDN connection using another S2a signaling interface.

18. The apparatus of claim 15, wherein the first IP connection is associated with an IP version 4 (IPv4) non-seamless wireless offload (NSWO) connection within the trusted access network and the second IP connection is associated with an IP version 6 (IPv6) packet data network (PDN) connection via a 3rd Generation Partnership Project (3GPP) network with an IPv6 access point name (APN).

19. The apparatus of claim 15, wherein the first IP connection is associated with an IP version 6 (IPv6) non-seamless wireless offload (NSWO) connection within the trusted access network and the second IP connection is associated with an IP version 4 (IPv4) packet data network (PDN) connection via a 3rd Generation Partnership Project (3GPP) network with an IPv4 access point name (APN).
