    • (newAlarms, clearedAlarms)

  • Work topics: Ongoing & Discussions - As before:

    • WG11 Security updates

    • OAM model updates from WG10

    • Topology?

      • Lots of existing models -

        • 3GPP, IETF network topology, O-RAN (WG10), onf-tapi, tmforum 

      • @John Keeney (Ericsson EST) Lets work together to try get some of the data generated by Simulated Topology Generator into OSC TEIV repository - but we need to work on intermodel-relationship modelling.

• @subhash 

  • J Release

    • Main update was in platform improvements

  • K Release

    • Spec alignment with O-RAN Arch. & specs - esp for training services

    • Would like to work alot more on integration

      • Ref above NONRTRIC integration, R1 for rApps, sample rApp, etc.

• How to use/embed an Ml-Model in an rApp?

  • @John Keeney (Ericsson EST) Spec is very unclear how rApps use ML models or the AI-ML-Platform / model store.

  • Pre-spec implementation of NONRTRIC rApps can use KServe ML models - where KServe-wrapped ML Models can be LCM'ed as part of rApp LCM

    • Ref: Sample rApp: https://github.com/o-ran-sc/nonrtric-plt-rappmanager/tree/master/sample-rapp-generator/rapp-kserve 

    • Can be used/LCM'ed using rApp Manager: https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-rappmanager/en/latest/ & Release J: rApp Manager

ONAP Update (@N.K. Shankaranarayanan)

• No update this week

ONAP/OSC Usecases (@N.K. Shankaranarayanan)

• No update this week.

Questions / Comments / AOB:

• @subhash Anyone know if/how to implement stuff in CTRs as pre-spec implementations?

  • Please check with CR author - easier if your company is a co-author of CR.

  • After CR is approved, and spec is approved, then the 'O-RAN license' applies.

  • Gets difficult if the accepted spec-version diverges from the implemented pre-spec version

  • Need to be careful about checking copyright & protected IP of CRs, and later when approved. (60 days after approval, IP declarations should be completed)

  • ( ^ Statements above are just our understanding, and may not be correct!. Consult an IPR specialist )
