1  Scope  p. 8

The present document specifies the group management protocols needed to support Mission Critical Services (MCSs).
Group management applies only when the UE operates on the network.
MCSs are services that require preferential handling compared to normal telecommunication services, e.g. in support of police or fire brigade.
MCSs can be used for public safety applications and also for general commercial applications (e.g., utility companies and railways).
The present document is applicable to User Equipment (UE) supporting the group management client (GMC) functionality, to application servers supporting the group management server (GMS) functionality, and to application servers supporting the Mission Critical Push To Talk (MCPTT), the Mission Critical Video (MCVideo) and Mission Critical Data (MCData) server functionality.
