4G EPC CUPS Explained: S-GW/P-GW Separation & Architecture Deep Dive

[First 2 Lines]: Understand the "Surgical Split" of the 4G EPC. We break down how Control and User Plane Separation (CUPS) transforms the S-GW and P-GW for 5G-readiness. [Full Summary]: The principle of CUPS is simple: we take the complex, coupled functions of the S-GW and P-GW and split them into two independent network entities—the Control Brain and the User Muscle. In this session, we cover: S-GW Separation: How the S-GW-C handles mobility coordination while the S-GW-U moves local traffic. P-GW Separation: Why the P-GW-C remains the IP anchor while the P-GW-U acts as the ultimate data gate. Protocols: The role of PFCP, GTP-C, and the Gx interface in a CUPS environment.
