This document compiles requirements to ensure that an Evolved Packet System can cope with the rapid growth in IP
data traffic and demanding requirements for new multimedia type of applications in terms of performance and quality, delivered to the user, whilst at the same time enabling cost effective deployment and operation.
The Evolved Packet System (EPS) is a higher-data-rate, lower-latency, packet-optimized system that supports multiple RATs. The focus of the EPS work is on enhancement of Packet Switched technology to cope with rapid growth in IP traffic.
The objectives of the EPS are to:
Provide higher data rates, lower latency, high level of security and enhanced QoS;
Support a variety of different access systems (existing and future), ensuring mobility and service continuity
between these access systems;
Support access system selection based on a combination of operator policies, user preference and access network
Realise improvements in basic system performance whilst maintaining the negotiated QoS across the whole
Provide capabilities for co-existence with legacy systems and migration to the EPS.
