The main function of UPF in 5G is the routing of traffic between the Radio Access Network (RAN) and other external networks. The RARE/FreeRTR use case not only offers the advantage that UPF packet processing can be offloaded for improved performance but also allows full control of traffic. The UPF implementation developed in the RARE/FreeRTR use case employs the Packet Forwarding Control Protocol (PFCP) to communicate with the 5G Session Management Function (SMF) that is responsible for monitoring and managing PDU sessions. Forwarding and tunnelling of user data is achieved with the GPRS Tunnelling Protocol (GTP) and its encapsulation/decapsulation.
