Feasibility Study on Multimedia Priority Service (MPS) Phase 2
The present document studies voice, data transport, and video use cases and identifies potential requirements for Multimedia Priority Service (MPS). It identifies where updates are needed to TR 22.953[3] and TS 22.153 [2] to account for current and anticipated MPS User needs for priority voice, data, and video communication capabilities.
The present document provides use cases and the associated potential new stage 1 requirements beyond those documented in TR 22.953 [3]. Example use cases include:
• MPS for Voice: MPS for MMTEL voice and voice teleconferencing invoked from a subscribed UE, and MPS for MMTEL 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, and
• MPS for Video: MPS for MMTEL video, MMTEL video conferencing, and streaming video invoked from a subscribed UE and MPS for video teleconferencing invoked from a video server by the host.
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.
