GCSE QoS, Priority and PreemptionStatic Dynamic Policy- based
• Fixed commitment • Dynamic resource • Dynamic resource of resources when assignment as calls assignment based device powers on - are established – on pre-defined user’s provisioned through signaling on policies: User, App level of service the Rx interface type, Service level
• Quality of Service (QoS) - guaranteed level of service based on parameters such as packet priority, delay budget, packet error loss • Priority - manage which users get access to the network resources during times of congestion • Preemption - remove active sessions of lower priority users and allocate resources to higher priority users when network resources are scarce or fully occupied QoS – an analogy QoS, Priority and Preemption – in action PTT PCRF Rx (Diameter) NO CONGESTION
QCI & ARP QCI and ARP User role / Location / GBR requested per call leg As per Rx request Good quality for all calls Application based User role, location, Application priority and priority & preemption Gx Bearer preemption requested for every leg of PTT Handshaking to configure GBR creation SGi PGW SGW - Admission control Bearer QCI and ARP enforced GBR created
CONGESTION ! eNodeB
PTT has higher priority than VoLTE QCI and ARP enforced User role, Location, Application based priority/preemption Mission critical video Responder Initiated or Command Centre requestedStream a video to other Live video stream officers and command center.
By selecting a group of people in the map and clicking on the “Stream” button. All team members will be notified about incoming video.
From the command center you can request or force video and you can also monitor, join or end any video session that is happening. Mission critical video Push from ground Dispatcher
Mobile Streamer Stream video to a single contact, talkgroup, or Quick Group
Mobile Receiver Incoming video stream is notified or barged (app setting) with tone. Video streamer’s ID provided. PTT call audio & Video audio are mixed or PTT call audio has priority (app setting) Past streams show in history.
Mobile Group Dispatch streamer Member Monitored talkgroups show active video streams. Dispatcher can switch between active video streams. Past streams shown in history. Mission critical video Request from dispatch
Dispatcher Dispatcher requests video from mobile user If Confirmed – request is sent to mobile, user accepts and starts video If Unconfirmed – request is sent to mobile, device starts video automatically
Dispatcher
Mobile Streamer Monitored talkgroups show active video streams. If Confirmed – accepts request, sends video Mobile Streamer If Unconfirmed – video sends automatically without user input 4G, MC Standards and 5G W I R M C T

A group within TCCA / CCBG is working out What is actually needed? What are the use cases? What can we learn from the latest plug test? What IOP testing should be done in TCCA? What testing needs to be done by individual operators? Thank You
