This document specifies the session control protocols needed to support Mission Critical Push To Talk (MCPTT). It specifies both on-network and off-network protocols.
Mission critical communication services are services that require preferential handling compared to normal telecommunication services, e.g. in support of police or fire brigade.
The MCPTT service can be used for public safety applications and also for general commercial applications (e.g., utility companies and railways).
This document is applicable to User Equipment (UE) supporting the MCPTT client functionality, and to application servers supporting the MCPTT server functionality.
