Enabling Three mission critical services

Mission Critical Push To Talk (MCPTT)

  • Prearranged, chat, broadcast and ad hoc group calls with floor control and queueing
  • Private calls in every commencement mode, first-to-answer, ambient listening
  • Emergency and imminent-peril calls, alerts, priority pre-emption
  • End-to-end protected media (GMK and PCK) and signalling

Mission Critical Data (MCData)

  • Short data (SDS) over signalling and media planes: one-to-one, group, ad hoc
  • File distribution over HTTP and the media plane, with disposition notifications
  • IP connectivity, enhanced status, functional aliases
  • Message store with notification channels, location

Mission Critical Video (MCVideo)

  • Group and private calls with transmission and reception control
  • H.264 video checked picture by picture at every receiver
  • Video pull and push, server recording, ambient viewing
  • Calls between two MC systems, directly or through MC gateways
