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).

3GPP TSG SA WG6 - Mission-critical applications is in charge of:

• Defining, evolving and maintaining 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.
• The application layer aspects in 1), with emphasis on the following.
• Work with relevant groups from other SDOs to make use of expertise available to support the development of specifications under the responsibility of SA6.
