3.1 Definitions p. 7
For the purposes of the present document, the terms and definitions given in TS 23.234 and the following apply:
3GPP - WLAN Interworking:
used generically to refer to interworking between the 3GPP system and the WLAN family of standards
interworking WLAN:
WLAN that interworks with a 3GPP system
Serving WLAN:
interworking WLAN that the user is connected to, i.e. either a visited or a home WLAN
Visited WLAN:
interworking WLAN that Interworks only with a visited PLMN
WLAN UE:
UE (equipped with UICC card including (U)SIM) utilized by a 3GPP subscriber to access the WLAN interworking
External AAA Server:
The External AAA Server is located in an external packet data network. The PDG interworks with the External AAA Server via the Wi reference point.
