SA6 - Mission-critical applications

The responsibility of SA WG6 includes the following: definition, evolution and maintenance of Stage 2 technical specification(s) for application layer functional elements and interfaces supporting critical communications and other applications (at the application layer), based on Stage 1 service requirements from SA1, including:

• Relevant application architectural aspects (including both network and terminal aspects)
• Definition of reference points for interactions between application functional elements
• Allocation of application functions to particular subsystems and elements
• Generating information flows between reference points within scope
• Identification of application layer protocols
• Necessary support for enabling interworking with non-3GPP applications
• Identify and provide application level functional requirements to other 3GPP WGs, according to their expertise, where additional functionality needs to be specified that impacts existing architecture, reference points, interfaces, protocols or transport bearer capabilities provided by the 3GPP-based system (e.g. IMS, EPS, ProSe)
