Abstract
Methods and apparatus for supporting EAP re-authentication for devices, e.g., UEs, connecting to APs such as WiFi APs, which are not 3GPP base stations such as gNBs are described. In accordance with the invention an ER service which supports EAP re-authentication is incorporated into an NSWOF which is coupled to multiple different APs. Once authenticated through the NSWOF via an EAP authorization process the ER service in the NSWOF stores UE re-authorization information and uses the information to re-authenticate a UE when it attaches to another AP to which the NSWOF is coupled. By supporting EAP re-authentication the need to contact an AUSF as part of a full authentication process is avoided and a UE can rapidly move between APs without having to perform a full EAP authentication involving contacting the AUSF each time the UE moves.
