Abstract

Embodiments describe methods, apparatuses and logic for a user equipment (UE) to connect to an access point (AP) in a wireless local area network (WLAN) based on credentials from a UE'"'"'s home third generation partnership project (3GPP) network. In some embodiments, the UE may receive selection policy parameters from the WLAN including a network access identifier (NAI) realm. The UE may also receive selection policy parameters from the 3GPP network. The UE may compare the selection policy parameters of the WLAN with the selection policy parameters of the 3GPP network and discover roaming relationships between service providers and the relative priorities of different networks, and create a network list based on the comparison. The UE may then associate with an AP of the WLAN based on the prioritized network list.

Claims

1. One or more non-transitory computer-readable media comprising instructions to cause a user equipment (UE), when executed by one or more processors of the UE, to:

compare a network access identifier (NAI) realm received from an access point (AP) of a wireless local access network (WLAN) to one or more selection policy parameters of a third generation partnership project (3GPP) network; and

associate with the AP based on the comparison.

2. The one or more non-transitory computer-readable media of claim 1, wherein the instructions are further to cause the UE to associate with the AP based on a comparison of WLAN roaming consortium data or an organizationally unique identifier (OUI) of the WLAN with the one or more selection policy parameters.

3. The one or more non-transitory computer-readable media of claim 1, wherein the one or more selection policy parameters of the 3GPP network are 3GPP network roaming consortium data or organizationally unique identifier (OUI) data of the 3GPP network.

4. The one or more non-transitory computer-readable media of claim 1, wherein the instructions are further to cause the UE to generate a prioritized network list based at least in part on the comparison of the NAI realm to the one or more selection policy parameters of the 3GPP network.

5. The one or more non-transitory computer-readable media of claim 1, wherein the instructions are further to cause the UE to receive the one or more selection policy parameters from a 3GPP Access Network Discovery and Selection Function (ANDSF) entity or an interworking wireless local area network interworking mobile object (I-WLAN IWK MO).

6. The one or more non-transitory computer-readable media of claim 1, wherein the instructions are further to cause the UE to:

transmit a query comprising the NAI realm; and

receive the one or more selection policy parameters of the 3GPP network in response to the query.

7. The one or more non-transitory computer-readable media of claim 1, wherein the instructions are further to cause the UE to:

identify an identifier of the AP;

transmit a query that includes the identifier to the AP; and

receive, responsive to the query that includes the identifier, an indication of the NAI realm from the AP.

8. The one or more non-transitory computer-readable media of claim 7, wherein the query that includes the identifier is an Access Network Query Protocol (ANQP) Generic Advertisement Service (GAS) query.

9. A user equipment (UE) comprising:

a transceiver to communicate with an access point (AP) of a wireless local access network (WLAN) and communicate with an entity of a third generation partnership project (3GPP) network; and

a processor coupled with the transceiver, the processor to associate with the AP based on a comparison of a network access identifier (NAI) realm received from the AP to one or more selection policy parameters of the 3GPP network.

10. The UE of claim 9, wherein the processor is further to associate with the AP based on a comparison of WLAN roaming consortium data or an organizationally unique identifier (OUI) of the WLAN with the one or more selection policy parameters.

11. The UE of claim 9, wherein the one or more selection policy parameters of the 3GPP network are 3GPP network roaming consortium data or organizationally unique identifier (OUI) data of the 3GPP network.

12. The UE of claim 9, wherein the processor is further to generate a prioritized network list based at least in part on the comparison of the NAI realm to the one or more selection policy parameters of the 3GPP network.

13. The UE of claim 9, wherein the transceiver is further to receive the one or more selection policy parameters from a 3GPP Access Network Discovery and Selection Function (ANDSF) entity or an interworking wireless local area network interworking mobile object (I-WLAN IWK MO).

14. The UE of claim 9, wherein the transceiver is further to:

transmit a query comprising the NAI realm; and

receive the one or more selection policy parameters of the 3GPP network in response to the query.

15. The UE of claim 9, where the processor is further to identify an identifier of the AP, and the transceiver is further to:

transmit a query that includes the identifier to the AP; and

receive, responsive to the query that includes the identifier, an indication of the NAI realm from the AP.

16. The UE of claim 15, wherein the query that includes the identifier is an Access Network Query Protocol (ANQP) Generic Advertisement Service (GAS) query.
