Control and User Plane Separation
What is CUPS? Essential to 5G networks, CUPS reduces latency on application service, e.g. by selecting User plane nodes which are closer to the RAN or more appropriate for the intended UE usage type without increasing the number of control plane nodes. Also, CUPS supports increase of data traffic, by enabling to add user plane nodes without changing the number of SGW-C, PGW-C and TDF-C in the network. This is independent evolution of the CP and UP functions enabling Software Defined Networking to deliver user plane data more efficiently while maintaining full EPC media service set at the edge.
