Wireless local area network (WLAN) connectivity option discovery
In embodiments, apparatuses, methods, and storage media may be described for identifying a wireless local area network (WLAN) access point (AP) with which a third generation partnership project (3GPP) user equipment (UE) should connect. Specifically, the UE may receive an indication of one or more supported connectivity options of the WLAN AP. The UE may also receive an indication of one or more public land mobile networks that the WLAN AP is able to communicate with. The UE may then select whether the UE should connect to the WLAN AP based on the received indication(s) and a selection preference rule. Other embodiments may be claimed.
1. A user equipment (UE) comprising:
receive circuitry to receive, in an information element (IE), an indication of a public land mobile network (PLMN) with which a wireless local area network (WLAN) access point (AP) is to communicate via S2a connectivity over an S2a interface; and
WLAN circuitry coupled with the receive circuitry, the WLAN circuitry to:
identify a WLAN selection policy (SP) of an access network discovery and selection function (ANDSF) management object (MO) and a preference indicator of the ANDSF MO, wherein the preference indicator is separate from the WLAN SP and is to indicate preference of S2a connectivity; and
select, based on the preference indicator and the indication of the PLMN in the IE, the WLAN AP as a target to which the UE is to communicatively couple.
2. The UE of claim 1 , wherein the WLAN SP is an inter-system routing policy (ISRP) rule and the receive circuitry is further to receive the ISRP from a home access network discovery and selection function (H-ANDSF) or a visited ANDSF (V-ANDSF).
3. The UE of claim 1 , wherein the indication of the PLMN includes an indication related to a service of the PLMN.
4. The UE of claim 3 , wherein the receive circuitry is to receive the IE in an advertisement beacon from the WLAN AP.
5. The UE of claim 1 , wherein the UE further includes transmit circuitry coupled with the receive circuitry, the transmit circuitry to transmit an access network query protocol (ANQP) query to the WLAN AP; and
the receive circuitry is further to receive the IE in an ANQP response that is based on the ANQP query;
wherein the ANQP query or the ANQP response includes an indication related to a PLMN parameter of the WLAN AP.
6. The UE of claim 5 , wherein the IE is a PLMN List IE, the WLAN AP is a WLAN AP out of a plurality of WLAN APs, and the UE further comprises transmit circuitry coupled with the WLAN circuitry, the transmit circuitry to establish, based on a selection of the WLAN AP as a target to which the UE is to communicatively couple, a connection with the WLAN AP.
7. The UE of claim 1 , wherein the UE includes a baseband processor coupled with the WLAN circuitry.
8. One or more non-transitory, computer-readable media comprising instructions that, when executed by one or more processors, cause a user equipment (UE) to:
receive, from a wireless local area network (WLAN) access point (AP) in a plurality of WLAN APs, an information element (IE) that includes an indication related to a public land mobile network (PLMN) with which the WLAN AP is communicatively coupled via S2a connectivity of over an S2a interface;
identify a WLAN selection policy (SP) of an access network discovery and selection function (ANDSF) management object (MO) and a preference indicator of the AND SF MO, wherein the preference indicator is separate from the WLAN SP and is to indicate an S2a connectivity preference; and
select, based on the preference indicator and the indication related to the PLMN, the WLAN AP as a WLAN AP to which the UE should communicatively couple.
9. The one or more non-transitory, computer-readable media of claim 8 , wherein the WLAN SP is an inter-system routing policy (ISRP) rule received from a home access network discovery and selection function (H-ANDSF) or a visited ANDSF (V-ANDSF).
10. The one or more non-transitory, computer-readable media of claim 8 , wherein the instructions, when executed, further cause the UE to receive the IE in an advertisement beacon from the WLAN AP.
11. The one or more non-transitory, computer-readable media of claim 8 , wherein the instructions when executed, further cause the UE to receive the IE in an access network query protocol (ANQP) response from the WLAN AP.
12. The one or more non-transitory, computer-readable media of claim 11 , wherein the IE is a PLMN List IE, and the instructions, when executed, are to further cause the UE to establish, by the UE based on the selection of the WLAN AP, a connection with the WLAN AP.
13. The one or more non-transitory, computer-readable media of claim 11 , wherein the indication related to the PLMN is an indication related to a service of the PLMN.
14. One or more non-transitory, computer-readable media comprising instructions that, when executed by one or more processors, cause a device to:
generate an access network discovery and selection function (ANDSF) management object (MO) that includes a wireless local area network selection policy (WLAN SP) and a preference indicator, separate from the WLAN SP, to indicate an S2a connectivity preference; and
send the ANDSF MO to a user equipment for selection of a WLAN with which to connect.
15. The one or more non-transitory, computer-readable media of claim 14 , wherein the device is an ANDSF of a home public land mobile network.
16. The one or more non-transitory, computer-readable media of claim 14 , wherein the device is an AND SF of a visited public land mobile network.
17. The one or more non-transitory, computer-readable media of claim 14 , wherein the WLAN SP includes a validity area node to indicate a geographical location in which the WLAN SP is valid.
18. The one or more non-transitory, computer-readable media of claim 14 , wherein the WLAN SP includes a time-of-day node to indicate a time of day in which the WLAN SP is valid.
