  • Deployment of MCPTT AS VM  straightforward
  • Deployment of Client App
  • Rights must be granted while installing.
  • By default, no rights granted. Suggestion of “adb install” command modification.
  • Testing tool
  • 1st Stage: JFed
  • 2nd Stage: Triangle GUI
  • Quamotion to define user flow
  • Triangle tool to define TAP model (urban pedestrian, busy hours, …)
  • 3rd Stage: Remote Desktop to Keysight-connected computer
  • Keysight Test Automation Platform (TAP)
  • Tailored user flow provided by UMA with 130 seconds gap
  • Vysor to connect to the smartphone (install App, run App, MCPTT call, play with token, …)

Gathered results/outcomes

  • Channel characterization (RSSI, RSRP, CQI, …)
  • More fine-grained stats of CQI
  • RTT stats
  • Power consumption output
  • RAM consumption output
  • Pcap
  • Logcat
  • Timestamped clicking pattern
  • Sip messages by sectors (UE, network and server)
  • INVITE
  • 200 OK
  • Floor control (request and granted/idle/taken)

Different network and channel conditions

  • Pedestrian with good

quality channel (-90dBm)

  • EPA5 fading
  • Urban scenario in

crowded area (-100dBm)

  • ETU300 fading
  • Vehicular scenario away

from the cell (-110dBm)

  • EVA70 fading

Business impact

  • Position as technology provider to MC integrators demand:
  • The proper fulfillment of MC-grade KPI
  • The optimized power consumption to guarantee the operation
  • f the UEs batteries for first responders
  • Added value in delay and energy consumption Gain position over

competitors

  • First phase of a polished integration of QoS/QoE monitoring and

management in MCPTT AS product

  • Knowledge of self-product and technology limitation
  • New project opportunities – main one being 5GENESIS

Feedback

  • PERCCEVAL  identify a series of technical constraints in the

chosen platform.

  • From a technical perspective, the experience of the project

provides insights of the baseline performance of MCPTT solutions over commercial LTE deployments in terms of:

  • KPIs
  • Energy consumption
  • Adaptation of the platform to allocate deployments with mixture
  • f MEC-based and non-MEC services.

Post-mortem

  • “Mission Critical as a Service (MCaaS)”: Dynamic and flexible MCPTT VNF in different places of mobile network
  • Development of an automated post-processing tool semi-automated analyses of the MCPTT KPIs
  • Recognize Fed4FIRE+ as a pan-European deployment ready to test and verify next generation emergency networks
  • Evaluate the impact of “to-the-edge” migration mechanisms into MCPTT in terms of resiliency improvement and KPIs
  • Analysis of the impact of optimization mechanisms into e2e KPI(s)
  • 5G-like MEC-based MCPTT service.
  • Evolution of UE+App-side to reduce e2e delay.
  • Concepts to reality – 5GENESIS – Málaga platform - UMA
  • MCPTT to MCS – Nemergent and Airbus.
  • MEC by Telefónica, Orchestration by Atos, 5G-ready network by Athonet and RunEL, 5G-UE

by Eurecom.

  • Málaga police – end-user, first-responders.
