The present document studies data transport, video and messaging use cases and identifies potential requirements for Multimedia Priority Service (MPS). It identifies where updates are needed to TR 22.953
and TS 22.153
to account for current and anticipated MPS User needs for priority data, video and text messaging communication capabilities.
The present document provides use cases and the associated potential new stage 1 requirements beyond those documented in TR 22.953. Example use cases include:
MPS for Voice: MPS for conversational voice and voice teleconferencing invoked from a subscribed UE, and MPS for voice teleconferencing invoked from a voice server by the host,
MPS for Data Transport Service (DTS): MPS DTS communications invoked from a subscribed UE, a subscribed IoT device, and from an enterprise network,
MPS for Video: MPS for conversational video, streaming video, and video teleconferencing invoked from a subscribed UE and MPS for video teleconferencing invoked from a video server by the host, and
The present document also include security considerations.
NOTE: Both MPS users and Mission Critical users can use common mechanisms defined in MCData and MCVideo for group-based communication with priority. However, both MPS and Mission Critical users have some unique requirements to also use an operator's individual subscription-based commercial services (voice, video, data) with priority.
