Within the 3GPP Technical Specification Group Service and System Aspects (TSG SA), the main objective of 3GPP TSG SA WG2 (SA2) is to develop the overall 3GPP system architecture and services including User Equipment, Access Network, Core Network, and IP Multimedia Subsystem. The Radio Access Network architecture is under TSG RAN’s responsibility.
SA2 has a system-wide view and defines the main entities of the system architecture, and how these entities are linked to each other. SA2 also defines the main functionality and the information exchange between these entities.
SA2 is currently responsible for the 5G System and Evolved Packet System (EPS) Architectures including the 3GPP enhancements for multimedia services (including emergency services), IoT, and other market sectors/vertical industries related use-cases.
SA2 coordinates with other 3GPP WGs and all relevant Standards Developing Organizations (SDOs), industry fora, and Market Representation Partners (MRPs) for its specification work.
