Mission Critical Services

A Mission Critical Service (MCX Service) is a communication service that enables capabilities of Mission Critical Applications. The MCX service is provided to end users from Mission Critical Organizations and mission critical applications for businesses and organizations. An MCX Service is either Mission Critical Push To Talk (MCPTT), Mission Critical Video (MCVideo), or Mission Critical Data (MCData) and represents a set of requirements between two or more MCX Service types.

MCX Services are based on the ability to invoke, modify, maintain, and release sessions with priority, and deliver the priority media packets under network congestion conditions. These services are supported in a roaming environment when roaming agreements are in place and where regulatory requirements apply.

An MCX subscription allows users to receive priority services if the network supports MCX. MCX Users require the 5GS functionality for real-time, dynamic, secure and limited interaction with the QoS and policy framework for modification of the QoS and policy framework by authorized users.
