Evolved Packet Core (EPC) is a framework for providing converged voice and data on a 4G Long-Term Evolution (LTE) network. 2G and 3G network architectures process and switch voice and data through two separate sub-domains: circuit-switched (CS) for voice and packet-switched (PS) for data. This course gives an overview of the architecture of core networks.
EPC was first introduced by 3GPP in rel-8 of the standard. They decided to make the core network scaling independent, for that there was a requirement of separation of control traffic and user traffic. Because of this split in the network, operators can easily dimension and adapt their network. EPC consists of entities like MME(Mobility management equipment), HSS (Home subscriber server ), SGW (serving gateway), PGW (PDN gateway). MME deals with the control plane , which handles signalling related to mobility and security for E UTRAN access. HSS is a database which contains user related and subscription related information. The gateways SGW and PGW deal with the user plane . they transport IP traffic between the user equipment and the external networks.
This Course of LTE EPC covers the description of LTE EPC and its functionalities. It covers the description of all nodes in the network core. 3GPP specified support of multiple access technologies and also handover between these accesses. The EPS also allows non-3GPP access technologies to interconnect the UE and the EPC. this is known as interworking in the network. IP protocol is the main protocol for all types of services in it.
