MME or Source eNodeB triggers the handover.

The is the all-IP backbone of 4G LTE networks, designed to deliver high-speed data and integrated voice services by replacing legacy circuit-switched systems with a flattened, packet-switched architecture . Unlike 2G and 3G, where voice and data were handled separately, EPC treats all traffic as IP-based applications, improving efficiency and reducing latency. Core Architecture and Components

Manages Quality of Service (QoS) and controls flow-based charging in the network. Mobile Packet Core 3. Core Concepts Introduction to Evolved Packet Core - 3G4G MME or Source eNodeB triggers the handover

As the world shifted from voice-centric networks to data-centric ecosystems, the telecommunications infrastructure required a complete overhaul. Enter and its backbone, the Evolved Packet Core (EPC) .

To understand how data flows through an EPC, network engineers analyze specific signaling procedures called "call flows." The two most critical flows are the Initial Attach and the Data Download. 1. The Initial Attach Procedure (Registration) Core Architecture and Components Manages Quality of Service

Converts voice into digital data packets, allowing voice calls to be handled over the LTE data network rather than traditional circuit-switched lines. Resources for Detailed Study

The UE sends an paired with a PDN Connectivity Request to the eNodeB via Radio Resource Control (RRC) signaling. The eNodeB forwards this request to the MME over the S1-MME interface. Step 2: Authentication and Security Enter and its backbone, the Evolved Packet Core (EPC)

The central database. It contains subscription-related information, user profiles, and authentication keys.

Understanding the is fundamental for anyone diving into modern mobile telecommunications. Unlike previous generations that split voice and data into separate domains, the EPC introduces an all-IP, flat architecture designed for high-speed data and low latency . Core Architecture Components
