An evolution of the overall 3GPP system is required to ensure competitiveness in a long-term time frame. 

This Technical Specification marks such an evolutionary path from 3GPP Release 8 through to Release 16. 

TS 22.278 V16.2.0, Service Requirements for the evolved packet system (EPS), compiles requirements to ensure EPS can cope with the rapid growth in IP data traffic and demanding requirements for new multimedia type applications in terms of performance and quality, delivered to the user, while at the same time enabling cost-effective deployment and operation. 

The Evolved Packet System is characterised by:

• Reduced latency.
• Higher user data rates equating to broadband performance.
• Improved system capacity and coverage.
• Lower operational costs.

The TS describes high-level requirements in terms of user and operational aspects; basic capabilities; multi-access and seamless mobility; performance requirements for EPS; security and privacy; charging aspects.
