PrintTechnology talk: Evolved Packet Core supports LTE transition
A key part of the end-to-end Nokia Siemens Networks LTE solution is the Evolved Packet Core (EPC).
"LTE provides operators with several important benefits, including significantly increased peak data rates, increased cell performance, reduced latency, ability to be deployed in scalable bandwidths, co-existence with GSM/EDGE/UMTSHSPA systems, & reduced CAPEX/OPEX"
Alan Hadden,
President GSA
EPC is specified by 3GPP under its Service Architecture Evolution (SAE) banner, and provides connectivity between the radio network and the content and service networks. Furthermore, because all traffic flows through the EPC gateway it can act as the policy and charging enforcement point, enabling operators to stay in control of the use of network resources.
Nokia Siemens Networks’ EPC is built on our leadership in flat network architecture and our driving role in 3GPP standardization. It offers smooth migration paths for operators moving to LTE/SAE, as well as supporting a smooth evolution option to upgrade our current SGSN and Flexi ISN elements to 3GPP R8 through a simple software upgrade.
