It is important to point out that the keyword “network” refers to the complete system that provides services and not specifically to the transport and networking functions that are part of this system. In the mobile context, the examples of networks are the Evolved Packet System (EPS) delivering 4G services and the 5G System (5GS) delivering 5G services. Both systems include the RAN (LTE, 5GNR), Packet Core (EPC, 5GC) and transport/networking functions that can be used to construct network slices. A variant of Network Slicing configuration is show in the figure below.
