AOB:

• "5G RAN Slice PRB Prediction rApp" Presentation & demo from from Sunil N 

  • Slides:
    

  • Focus on optimised allocation of PRBs to different slices

  • Based on NSSI performance reports from RAN NSSMF (15min) 

    • Uses 1 week windows (80% for training, 20% for model testing

    • Tried several model types. Settled on LSTM. 

    • Used to predict DL PRB usage per NSSI (15 min) 

  • Current PRB prediction rApp policy - modify PRB allocations if ( predicted usage < current ) or ( predicted usage > current  * 120% )

    • When triggered queries past 1 week data from InfluxDB & predicts 

    • Updates sent direct to NSSMF API 

  • Currently performance data is written direct into InfluxDB, then publishes triggered by NSSMF notification

  • Uses simulated NSSMF (3gpp 28.532 interfaces & notifications) as rApp

  • Plan to move prediction service from inside rApp uService to AIMLFW platform 

  • Plan to extend to Uplink too. 

  • Next step: 

    • Create new wiki page for use case (landing page) in Integration wiki space 

    • Upload code, data, etc - initially in NONRTRIC rAppManager repo, but can re-file later
       

• Github Actions / Workflows Migration (@Matt Watkins, @John Keeney (Ericsson EST), @Martin Skorupski):
