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

  • Last week's TOC (Thursday):

    • No major update. See minutes.

  • This week's TOC (Tomorrow):

    • New meeting format with updates from relevant PTL etc

      • RSAC, Integration I (cross-project testing related), Infrastructure

      • Next week : RIC, RICAPP, AIMLFW

      • Week +2: NONRTRIC, SMO, OAM, SIM

      • Week +3: Integration II (lab related), O-DU-HIGH, O-DU-LOW

• Made progress on how to have multiple project in single repo.

  • Change conf.py & .readthedoc.yaml: https://gerrit.o-ran-sc.org/r/c/nonrtric/plt/ranpm/+/10991 

• Documenting & improving how to deploy RANPM funcions. Will demo again in coming weeks @Björn Magnusson 

  • @Joseph Thaliath in AIMLFW had soem issues & questions. Working on those.

• Will push on with work on rApp manager - especially rApp onboarding, preparing for SME, DME etc

  • Lots of bits there already ... this will tie them together in a coordianted way when deploying rApps

  • Much of the rAPP LCM will be handled by ONAP ACM functions

  • Main issue is we still have no clear definition of rApp package.

  • We will likely be out of alignment with O_RAN specs when they arrive / mature. We will evolve our work then.

• Will demo Service Registry & Service Discovery - based on CAPIF

  • Working now. @Yennifer Chacon 

• Will demo ONAP SO CNFM function for ASD-pacakaged CNFs deployment - working in standalone mode.

  • We've removed dependency on SDC and A&AI - replaced with initial stub functions.

  • So CNFM in standalone mode gives ASD deployment support - either on its own or as part of a larger ONAP SO/SDC/A&AI install.

  • Propose to demo at joint SMO/SO call, maybe 2 weeks? Or RSAC call in 2 weeks. @Aravindhan Ayyanathan 

• Otherwise continuing as per last week :

  • Consolidating PM data exposure in new repo for RAN PM functions
