LTE System Solutions

The overall EPS network architecture, including the network elements and the standardized interfaces is comprised of the EPC and the access network E-UTRAN. While the EPC consists of many logical nodes, the access network is made up of essentially just one node, the evolved NodeB (eNodeB), which connects to the UEs. Each of these network elements is interconnected by means of interfaces that are standardized in order to allow multi-vendor interoperability.

The functional split between the EPC and E-UTRAN is shown.

LTE EPS Network Elements are:

• UE
• eNodeB
• MME
• S-GW
• P-GW
