TS 22.278 – Evolved Packet System Service Requirements
3GPP TS 22.278 is the 3GPP Technical Specification for Evolved Packet System Service Requirements. Its official 3GPP title is “Service requirements for the Evolved Packet System (EPS)”. It is published in 12 releases (Rel-8 to Rel-19); the latest version is 19.0.0 in Rel-19.
Specifies service requirements for Evolved Packet System including 5G E-UTRA-NR Dual Connectivity, focusing on high data rates, low latency, and multi-access support.
This specification defines the service requirements for the Evolved Packet System (EPS), an evolution of 3G UMTS aimed at handling rapid IP traffic growth and demanding multimedia applications. It covers key features such as reduced latency, higher user data rates, improved capacity and coverage, and cost-effective deployment. The document includes requirements for 5G E-UTRA-NR Dual Connectivity in E-UTRAN connected to EPC, and addresses mobility, service continuity, and interworking with various access systems including non-3GPP networks. It is critical for enabling enhanced QoS, efficient resource usage, and support for voice, video, messaging, and data services across converged fixed-mobile networks.
