1. A method comprising:
determining the existence of a converged User Plane Function (UPF), wherein the converged UPF includes a Serving Gateway User Plane (SGW-U) session and a Packet Data Network (PDN) Gateway User Plane (PGW-U) session; and
in response to determining the existence of the converged UPF:
transmitting User Equipment (UE) information from a Serving Gateway Control Plane (SGW-C) session to the SGW-U session of the converged UPF; and
sharing the UE information received at the SGW-U session of the converged UPF to the PGW-U session of the converged UPF, wherein the PGW-U session receives the UE information without communicating with a PDN Gateway Control Plane (PGW-C) session.
