System and method for supporting 5G user devices in a legacy wireless core network

Abstract:

Systems and methods described herein enable improve handling of 5G-enabled devices in 4G core networks. The systems and methods described herein provide an enhanced HTTP-based interface between a SMF/PGW-C and a UDM to support interactions required to: (a) perform authorization of PDN access for non-3GPP networks, (b) provide an APN profile to the SMF+PGW-C for the PDN being setup, (c) update the SMF+PGW-C address in the UDM for the PDN being served by non-3GPP networks, and (d) provide operator-specific subscriber parameters from the UDM to the SMF+PGW-C for 3GPP and non-3GPP access.
