  • 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.

  • Patent number: 11889592
    Abstract: A system and method for reducing latency in a wireless-to-wired backhaul environment, such as a LTE-Backhaul environment. In the LTE-Backhaul embodiment, the system and method rely on a modification to the eNodeB (eNB). This modification causes the eNB to generate a bandwidth report (BWR) upon receipt of a buffer status report (BSR) associated with an RRC encapsulated NSA signaling. The BWR provides a notification to the backhaul system that SCTP signaling, which is associated with the RRC encapsulated NSA signaling, is forthcoming. In addition, the present system and method provides for a periodic transmission of a grant (e.g., a MAP in a DOCSIS embodiment) in the backhaul portion. The backhaul grant provides for the modem to immediately forward the BWR to the modem termination system (MTS) upon receipt of the BWR such that the MTS may prepare a grant for the forth coming SCTP signaling.
