Claim 12:
13. A method to authenticate a Non-Fifth Generation Capable (N5GC) device with a Fifth Generation (5G) core network, the method comprising:
generating, at a wireline-access gateway function (W-AGF), a Registration Request message on behalf of the N5GC device and in response to an Identity Response message associated with the N5GC device, the Registration Request message including a Subscription Concealed Identifier (SUCI) associated with the N5GC device and an N5GC indication;
sending the Registration Request message from the W-AGF to an Access & Mobility Management Function (AMF) of the 5G core network;
sending, using the AMF, a first Authentication Request message to an Authentication Server Function (AUSF) of the 5G core network based on the SUCI associated with the N5GC device, the first Authentication Request message including the SUCI and the N5GC indication;
selecting, at least partly in response to the first Authentication Request message, an authentication type for the N5GC device;
receiving, at the W-AGF and from the AMF, a second Authentication Request message associated with the 5G core network including an indication of the authentication type; and
forwarding the second Authentication Request message associated with the 5G core network to the N5GC device to cause the N5GC device to be authenticated for the 5G core network.
