4G LTE Evolved Packet Core (EPC) is a high-performance, all-IP (Internet Protocol) network architecture that provides a unified framework for both voice and data services. Unlike previous 2G/3G networks that used separate systems for voice (circuit-switched) and data (packet-switched), the EPC treats everything as IP data, significantly simplifying the network and reducing latency. 🚀 Key Features of 4G LTE EPC
Manages Quality of Service (QoS) and charging rules for data sessions. ScienceDirect.com Key Call Flows
The is the backbone of the 4G mobile network, designed to provide high-speed data and voice services over an all-IP (Internet Protocol) infrastructure . Unlike earlier 2G/3G networks, the EPC is a "flat" architecture that separates the control plane (signaling) from the user plane (data traffic) to improve efficiency and reduce latency. 1. Key EPC Concepts and Components
To understand call flows, you must first understand the nodes (hardware/software elements) that make up the EPC.
