  • Patent number: 11902779
    Abstract: Systems and methods to authenticate a Non-Fifth Generation Capable (N5GC) device on a Residential Gateway (RG) include a wireline access network comprising the RG and a wireline-access gateway function (W-AGF). The RG connects to the W-AGF using a termination system (e.g., a Cable Modem Termination System (CMTS) and the like) to relay N5GC device messages received at the RG to the W-AGF and vice versa. During a registration/authentication procedure for the N5GC device, the W-AGF generates a Registration Request message on behalf of the N5GC device and sends the Registration Request message to an Access & Mobility Management Function (AMF) of a Fifth Generation (5G) core network. The Registration Request message includes an indication that the N5GC device lacks 5G capabilities (e.g., is N5GC). In response to the Registration Request message, the system causes the N5GC device to be authenticated at least partly in response to the Registration Request message.
