Abstract

A control plane (CP) function for session management performs a procedure for establishing local traffic offloading for a user equipment (UE) in a mobile network having an Evolved Packet Core (EPC) and Fifth Generation (5G) converged core that supports communications via a Long-Term Evolution (LTE) radio access network (RAN) and a Fifth Generation (5G) RAN. Initially, a connection is established for the UE via the LTE RAN that includes a first bearer between the LTE RAN and a central serving gateway-user plane (SGW-U) at a central location, and a second bearer between the central SGW-U and a central packet gateway-user plane (PGW-U) at the central location. The CP function inserts a local SGW-U at an edge location and subsequently inserts a local intermediate user plane function (I-UPF) with an uplink classifier (UL-CL) at the edge location for enabling edge offload of traffic from the LTE RAN.
