. The User Plane Function (UPF) is a virtual network function (VNF) used to forward user traffic extremely fast. All user plane functions, such as Deep Packet Inspection (DPI), firewalls, or Network Address Translation

(NAT), are maintained under the UPF function. The User Plane Function in the 5G core network receives the data from the subscriber devices via a Next-Generation NodeB (gNodeB), and the signal quality is measured via the Radio Resource ControlProtocol (RRC).
