3GPP TSG SA WG1 - Services
The 3rd Generation Partnership Project (3GPP) is the primary body for developing technology specifications for cellular networks. It self-organises through its Working Groups coordinated by the Chairs of the Technical Specifications Groups (TSGs).
TSG SA (Service and System Aspects) has 6 active WGs.
The scope of SA1 - Services is on feature requirements applicable to mobile and fixed communications technology from 2G.
