The 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

The MME notifies the HSS that it is now serving this specific subscriber. The HSS responds by downloading the user's profile and service permissions to the MME.

The main control-plane node. It manages user equipment (UE) tracking, paging, authentication (by interacting with the HSS), and session management. It selects the appropriate S-GW and P-GW for the user.

The EPC consists of four main logical nodes that manage the connection between the user and external networks: Mobility Management Entity (MME):

Identifying which node (MME, SGW, PGW) caused a call drop.

When a 4G device powers on, it executes an Attach Procedure to register with the network and establish a default IP connection. The HSS responds by downloading the user's profile

The is the all-IP framework that serves as the core network for 4G Long Term Evolution (LTE). Unlike previous generations (2G/3G), which used separate domains for voice (circuit-switched) and data (packet-switched), the EPC unifies both into a single packet-switched domain. This "flat" architecture is designed to provide high throughput and low latency, essential for modern wireless broadband services. Core Concepts and Network Elements

The MME triggers an Initial Context Setup Request to the eNodeB. The eNodeB sends an RRC Connection Reconfiguration message to the UE to configure the radio parameters.

The EPC is the backbone of the 4G network, defined by 3GPP (Release 8 and onwards) to handle both user data and control signaling. Unlike 3G networks that used separate infrastructures for voice (Circuit Switched) and data (Packet Switched), the EPC is a unified, all-IP network.

An EPS Bearer is a logical tunnel with a defined QoS.
