The Evolved Packet Core (EPC) is the framework that provides converged voice and data on a 4G Long-Term Evolution (LTE) network. Unlike previous generations, the EPC features a flat, all-IP architecture that unifies circuit-switched and packet-switched sub-domains into a single packet-switched domain. Core Concepts of LTE EPC

HSS (Home Subscriber Server): A central database containing subscriber profiles and authentication vectors required by the MME to verify users.

Part 3: The LTE Identifiers

Before a call flow begins, the network identifies the user and the device. HSS (Home Subscriber Server) : A central database

PGW (Packet Data Network Gateway): The interface between the LTE network and external IP networks (like the Internet). It allocates IP addresses and enforces Quality of Service (QoS) rules.

Packet Data Network Gateway (PGW): The interface to external networks (like the internet). It allocates IP addresses to devices and enforces data usage policies. It allocates IP addresses and enforces Quality of

Step 5: Session Creation (The heart of EPC)

Initial Attach: The UE sends an Attach Request to the MME via the eNodeB.
