The EPC is a flat, all-IP architecture designed to reduce latency. It consists of four primary network elements: It consists of four primary network elements: The

The EPC connects the (Evolved Universal Terrestrial Radio Access Network, or the eNodeB base stations) to external networks such as the internet, IMS (IP Multimedia Subsystem), or corporate networks. Key Characteristics of EPC All-IP Network: Supports voice and data over IP. LTE supports two primary handover types:

When a UE moves between cells, the network must preserve service continuity. LTE supports two primary handover types:
