SA WG6 - Application Enablement and Critical Communication Applications


Within the 3GPP Technical Specification Group Service and System Aspects (SA), the 3GPP TSG SA WG6 (SA6) is the application enablement and critical communication applications group for vertical markets. The main objective of SA6 is to provide application layer architecture specifications for 3GPP verticals, including architecture requirements, functional architecture, procedures, information flows, interworking with non-3GPP application layer solutions, and deployment models as appropriate.

SA6 is currently responsible for application layer specifications, with emphasis on the following:

  • Critical communication applications (e.g. Mission Critical services for public safety, railways)
  • Service frameworks (e.g. Common API Framework, Service Enabler Architecture Layer, Edge Application enablement, Messaging enablement)
  • Enablers for vertical applications (e.g. automotive, drones, smart factories).
