Status:

  • Viavi had meetings with James and Subhash - no access yet.
  • Bouncer xApp:
    • committers changed
    • code checking not started yet - maybe start this week
    • Matti discussed with Brazilian professor about first steps towards replicated xApps with Bouncer as an example.
  • AD & QP xAPP:

    • Got the VIAVI simulator access and exploring the simulator for different UE level scenarios - facing issue (simulator stop, black screen) - Viavi shared sample data to bypass simulator use

    • Getting issues in data generation. Raised the issues with the Viavi team.  Viavi team shred the sample data. We are working on that.

    • InfluxDb – Checked in ric/deb repo, but Felix asked to put the files in  [it/dep.git] /ric-common/Common-Template/helm/ric-common/templates /

      • Need further clarification from Felix - Matti will try to get Felix to join HCL call

    • Nikhil having problems with AD/TS - Chandru replied.
  • Anomaly detection use case flow and dev. resources confirmed: AD-TS-flow.pptx
  • KPIMON:
    • Update by email: Influx update added - Samsung promises to check in code now.
  • LP xApp (ChinaMobile):
    • update by email: James working with Viavi - may need a new RMR message type.

  • Bouncer xApp:
    • code checking started?
  • AD & QP xAPP:
    • Active communication with Viavi - still some issues
  • HW:
    • C++: Refactoring between xApp and c++ framework moving slowly.
    • Python/go (Samsung):
      • python: E2AP - HeeWon + RIC-687.
      • go: E2AP - no new updates. Will try out this week to send an E2 message.
    • Open lab access: Common RIC installation. Matti worked with Felix but I guess the Apparently VM is still not there. there but no access yet? Matti will continue bugging Felix.
    LP xApp (ChinaMobile)
  • Slow moving items:
    • Updates?
    • SSP (Samsung): Initial discussion -
    will use some E2SM NI message.

    • See if ONF simulator could be used with OSC RIC (Samsung, Nokia also members) -
    see what collaboration would be possible - still to be done.Viavi binary in OSC lab - yes.
    • should be possible if E2 AP and KPM versions match (KPM 2.0.3 if I heard correctly)
    • Subhash: Committer changes needed (Rahul → Naman)
    .Madan needs help with Robo - Sunil will help
    • - Matti needs to start the vote (today).




==============================================

...

  • "Portability SDK" repo request revised and still waiting for enough TOC votes.
  • Viavi simulator discussions to support AD use case:

    • The goal of the scenario is to simulate an anomaly where a small set of UEs are not getting adequate signal strengths due to some temporal event in their locality.

       The RIC will detect the anomaly and may take corrective actions.

       The RAN Simulator will group users into indoor, pedestrian and vehicle groups. Some outdoor users will have less than average throughput and the RIC should identify these as outliers and take action to improve performance. Chosen UEs will fall below a throughput threshold for a period due to an obstacle blocking the signal, which is represented as a shadow-region on the topology map.
