V14.2.0 (PDF)    2017/12    381 p.


Rapporteur:  Dr. Patel, Milan
See also:  MCVideo-related TS/TR    

The present document specifies the signalling control needed to support Mission Critical Video (MCVideo) service.

The MCVideo service and its associated media plane control protocols 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 MCVideo client, and MCVideo server.
