A communication system for transmitting data packets includes: at least one Access Node (AN) connectable to a user equipment (UE); a User Plane Function (UPF) component; and a data network (DN). The UPF component is a distributed component and comprises: at least one User Plane Function Edge (UPF-E) component and a User Plane Function Core (UPF-C) component, the UPF-E component being connected between the at least one AN and the UPF-C component, and the UPF-C component being connected between the UPF-E component and the data network (DN) or another UPF-C; and a UPF Management (UPF-M) component configured to terminate an N4 interface.
