OSC Project roundup:

News from OSC TOC & OSFG & RSAC calls last week

  • TOC: 

    • https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/#ORANSCTechnicalOversightCommittee(TOC)

    • Last week's TOC (Thursday):

      • David wants much better attendance/representation at TOC & RSAC calls. 

        • We feel that the projects represented here are already well represented in general, but could improve a little as requested. 

        • We'll aim to always be available for comments/questions/clarifications as needed. 

      • May need some changes in OSC & OSFG charters. TOC members are requested to be available for F2F meetings. 

    • This week's TOC (Thursday):

  • OSFG: (@Martin Skorupski)

    • OSFG meetings (August):

      • Agenda, Minutes, etc : https://oranalliance.atlassian.net/wiki/spaces/OSFG/pages/2292154442/OSFG+Meeting+Minutes  (Access restricted to O-RAN members/contributors)  

      • SCCL still in progress 

      • OSFG F2F 

        • Still working through the outcomes & preparing a proposal/feedback to O-RAN EC.  

        • Discussions will continue before & during F2F 

        • OSFG has requested 3 sessions - including demos. 

        • Lots of proposals for how to re-arrange projects etc. 

        • Proposal in progress for O-RAN leadership at F2F 

          • More detail will emerge in coming weeks as discussion & proposal matures.

          • Keep watching OSFG & TOC meetings 

      • WG11 have asked OSFG to enforce a requirement to OSC to change messaging / positioning of OSC wrt quality/security of OSC code 

        • Ref: OSC's CVE handing procedure

        • Ref: OSC website: https://o-ran-sc.org/ 

        • Ref: OSC wiki: O-RAN SC 

        • All need updates to make the quality/security stance clear. 

        • Updates in progress.

AOB:

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

    • Great demo last week. Thank you 👍😊

    • Having some problem pushing PRs to Gerrit. Working on it. 

    • Suggest a wiki page for any additional useful information.

    • Last week:

      • 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
