LTE/EPS Technology: Core Network

The 3GPP evolution for the 3G mobile system created the new base station system, called Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) and a new core network, called Evolved Packet Core (EPC) as a result of two standardisation projects: Long Term Evolution (LTE) and System Architecture Evolution (SAE).

Outline

Security in the Evolved Packet System

Security is a fundamental building block of wireless telecommunications systems. It is also a process – new threats are discovered over time, forcing communication systems to evolve.

LCS Architecture for LTE EPS

3GPP considered 5 architecture alternatives for LCS during study and selected the one explained further according to 3GPP Release 9.
