A. Evolved Packet Core (EPC)
Evolved Packet Core is the IP-based core network
defined by 3GPP (Telecom standard) for use with LTE and
other access technologies. The goal of the EPC is to provide
simplified all IP core network architectures to efficiently give
access to various services such as the ones provided by IMS
(IP Multimedia Subsystem). EPC consists essentially of a
Mobility Management Entity (MME) & access agnostic
gateway foe routing of user datagram. EPC will be a
completely new architecture for wireless operators, one that
emulates the IP world of data Communication rather than the
