Claim 18:
19. A method to authenticate a Non-Fifth Generation Capable (NSGC) device with a Fifth Generation (5G) core network, the method comprising:
sending an Identity Request message from a wireline-access gateway function (W-AGF) to the NSGC device, the W-AGF being connected to the NSGC device through a residential gateway (RG);
receiving, at the W-AGF, an Identity Response message including a device identifier associated with the NSGC device;
generating, at the W-AGF, a Registration Request message on behalf of the NSGC device including an NSGC indication;
sending the Registration Request message from the W-AGF to an Access & Mobility Management Function (AMF) of the 5G core network;
receiving, at the W-AGF and from the AMF, an Authentication Request message associated with the 5G core network in response to the Registration Request message;
forwarding the Authentication Request message associated with the 5G core network to the NSGC device to cause the NSGC device to have an authenticated status with respect to the core network;
sending, from an Authentication Server Function (AUSF) of the 5G core network to a Unified Data Management (UDM) of the 5G core network, an Authentication Result Confirmation Request message including at least the device identifier associated with the NSGC device; and
storing, at the UDM and in response to the Authentication Result Confirmation Request message, an indication of the authenticated status corresponding to the NSGC device.
