Once the UE arrives at the new cell, the MME tells the S-GW to switch the user plane path to the target eNodeB. 3. UE-Requested PDN Connectivity

If you're interested in learning more about EPC concepts and call flows, here are some resources you can download:

Whether you are preparing for a telecom interview or simply curious about how your phone connects to the internet, mastering these EPC concepts and call flows is the foundation of understanding 4G and, by extension, the transition to 5G Core networks. Once the UE arrives at the new cell,

The MME communicates with the HSS to authenticate the UE and establish security keys.

You wake up, disable airplane mode → Your phone says "Hey tower, I'm back" → MME asks HSS "Is this user legit?" → PGW assigns an IP address → You see "LTE" in status bar. The MME communicates with the HSS to authenticate

To understand call flows, you must first understand the nodes (hardware/software elements) that make up the EPC.

4G LTE Evolved Packet Core (EPC) is a flat, all-IP framework designed to provide converged voice and data services with high throughput and low latency. It separates control and user planes to handle mobility and data sessions efficiently. Core Concepts of EPC 4G LTE Evolved Packet Core (EPC) is a

architecture, its core concepts, and the signaling call flows essential for network operation. 1. Introduction to EPC Evolved Packet Core (EPC)
