## Abstract

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.

## Claims

### Claim 1

A user equipment (UE) comprising:
receive circuitry to receive, in a public land mobile network (PLMN) list information element (IE), an indication of a PLMN with which a wireless local area network (WLAN) access point (AP) is to communicate via S2a connectivity over an S2a interface between the WLAN AP and the PLMN; 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 separated from the WLAN SP and preferences selection of WLAN with S2a connectivity; and
