When the WLAN is considered as trusted by the operator, the Trusted WLAN Access Network (TWAN) is interfaced with the EPC as a trusted non-3GPP access via the STa interface to the 3GPP AAA Server/Proxy and the S2a interface to the PDN-GW.

Roaming scenarios where the TWAN does not support a STa interface to the UE's registered PLMN or to the UE's HPLMN are not supported in this release of the specification.
