How different cores in LTE stack designed?

Answer»

The EVOLUTION of LTE entails a whole new core network with a flat, all-IP based architecture. The SAE DEFINED by 3GPP has the Evolved Packet Core (EPC) as its main component and Mobility Management ENTITY (MME), Serving Gateway (SGW) and PDN Gateway (PGW) as the subcomponents. The introduction of this new architecture implies that telecom equipment manufacturers need to either undertake a MIGRATION of their current packet core platforms or develop a new evolved packet core ground up.
