TSG SA – Service and System Aspects

3GPP TSG Service and System Aspects (SA) is responsible for the overall architecture and service capabilities of systems based on 3GPP specifications. Consequently, 3GPP TSG SA is responsible for the cross 3GPP TSG co-ordination.

SA is responsible for the technical co-ordination of the specification work done in the following Working Groups:

SA WG1 – Services
SA WG2 – System Architecture and Services
SA WG3 – Security and Privacy
SA WG4 – Multimedia Codecs, Systems and Services
SA WG5 – Management, Orchestration and Charging
SA WG6 – Application Enablement & Critical Communication Applications.

SA is currently responsible for the following areas of work:

- - Overall development, coordination and evolution of 5G and LTE technologies;
  - Overall coordination between 3GPP TSGs and 3GPP SA WGs;
  - Service and feature requirements (stage 1 development);
  - Architecture of the 3GPP Core Network and the overall 3GPP system;
  - Security and privacy of the 3GPP system;
  - Codecs and their transport;
  - Multicast/broadcast streaming and real-time communication;
  - Management and orchestration of 3GPP system components;
  - Charging;
  - Enablers for vertical applications and general 3GPP services.
