eMBMS based MCx Field Use Cases in 5G scenario

Some use applicable to mission critical comms services in the world of 5G Wireless deployments.

1. MCX Use Cases in 5G

2. eMBMS MCx Field Use Cases S ite Awareness ( MCData ) Firemen can receive building layouts and floor plans on their devices including the live positions of their teammates. eMBMS pushes maps and location updates continuously to the team in the field. Managers can see in realtime which members of the team need assistance. Rich details (MC Video) When there is a fire or accident the first responder arrives. Few people go inside to check the scene and report back to team . The live camera stream is streamed via eMBMS in the surrounding area. With the video the team can make a better assessment of the actual situation. Mining communications with MC-PTT A push-to-talk group is created between groups or all the people working in the mine. MCPTT over eMBMS is activated to send the downlink audio stream. Improved reception quality enhances the communication between teammates, with no network congestion

3. MME MBMS Network Architecture

4. Test Scenario Configurable Parameters ‍Call session length Concurrent calls/endpoints BHCA/CPS 3GPP Release-14 --- On-Network operations Mutually agreed Test Plan to be developed

5. Key KPIs for E2E Testing Critical QCIs as per 3GPP TS 23.203 v16.2.0 (2019-12): GBR – Guaranteed Bit Rate QCIs 65, 69 & 70 were introduced in 3GPP release 12. QCI 67 was introduced in release 15. KPI1: Push-to-talk request access time < 300ms KPI2: End-to-end MCPTT access time < 1000ms KPI3: Mouth-to-ear latency < 300ms KPI4: Max late call entry time < 150ms (encrypted 350ms) per 3GPP TS 22.179 User KPIs Other possible KPIs Call Setup Time Post Dial Delay Post Pickup Delay Call Teardown Time Media Delay MCPTT Access Time End-to-end Access Time Mouth-to-Ear latency
