23.0023GPPNetwork architectureRelease 17TS
The configuration of the 3GPP/WLAN interworking function is presented in figure 8. The figure shows all network entities and reference point for the roaming scenario when a WLAN UE accesses PS based services in the home network. PS based services in the visited network are accessed via a Packet Data Gateway in the visited 3GPP network. Reference point Ww between WLAN UE and WLAN is outside the scope of 3GPP and only shown for completeness.
