  • Last week's TOC (Thursday):

    • See minutes

  • This week's TOC (in 2 days):

    • Update on SMO-related topics this week

• Service Exposure Manager - New function pulling together previous work

• O-RAN Spec API compliance for R1-SME, R1-DME, R1-A1, A1

• Mostly same as last week:

  • Updating sonar scans and related updates to improve results: making good progress

  • Making good progress on rApp manager.
    
    

    • Adding support for DME integration now. Will demo again in a few weeks.

  • OpenAPI-first in A1-PMS & ICS

    • Change from code→openapi→docs to openapi → code-stubs & docs

    • To better align with R1 specs as they mature

    • To improve expressiveness of docs etc.

    • Working now - tested functional equivalence achieved - merging this week. Then more work to follow.
      
      

  • Some changes in A1-Mediator in near-RT-RIC plt in H-Release.

    • Meeting planned with Near-RT-RIC team tomorrow.

    • Further investigation needed re effects on A1-PMS/ICS & A1-SIM

    • Looks like OSC_v2.1.0. A1-AP (P) profile will b deprecated

      • Will phase out support A1-SIM and A1-PMS in coming releases, when A1-Mediator moves to spec version of A1-AP

    • Need to verify current implementation are fully spec compliant

    • Working on Pairwise test - will be ready as A1-Mediator implementation continues (few weeks)

      • Received info on how to start A1-Mediator in standalone mode - easier to test.

    • Still work in progress. Please edit and add a review.

    • Hoping to make progress in coming weeks.

  • https://lf-o-ran-sc.atlassian.net/browse/OAM-349

• No update this week

• Details of using CPS is still ongoing
  
  

  • Quite complex ...

    • How to interact/integrate SDNR & CPS, e.g. mounted netconf device models, CM notifications

    • VES vs Netconf id mapping is very tricky & must be maintained.

      • Decision: CM handle in CPS is same as Netconf server ID in RANSIM & same of NF ID & same as sourceID in VES message.

  • Also relevant for O-RAN SMO sequence flow work (@N.K. Shankaranarayanan)

• Ref: RSAC meeting 20/Sep - Slides & video @ 2024 RSAC Meetings 

• Still very unclear how it/dep deployment works & if it is maintained.

• Work from Taiwan Lab should / could be reusable hopefully.

• Meeting with ONAP OOM team last week to iron out technicalities of deploying ONAP functions

  • https://lists.onap.org/g/onap-meetings/viewevent?repeatid=31908&eventid=2003085&calstart=2023-10-04

  • Detailed discussion on deployment etc, version without AAF,  @Byung-Woo Jun Andreas, Louis Lie, @N.K. Shankaranarayanan & others

    • Discussions & Emails currently ongoing.

  • Use case? : None apparent yet - focus on deployability & DI/CD as a use case.

• There have been updates since OAM function version in it/dep / ONAP worked

  • e.g. VES collector needs to be built (3gpp)

  • e.g. OAM gateway (sdnc, keycloak, dmaap, ves collector are now behind gateway for ease of addressing)

• SIM / topology ... still pretty similar - but very use case specific

• NONRTRIC ... Charts in it-dep/nontric directory are up to date. Charts/configurations in it-dep/smo-intall are a little dated, but not too bad.

• Main question is where does platform stop & use case start .. Alot of the charts/deployment is use case specific.

• PM flows

  • PM Streaming above as an example of SMOS mapped into WG10 SMO sketches/proposals

• Short update from last week:
  
  

  • Discussion continue in WG1 re AI-ML inclusion in flows.

  • Include service Orchestration function?

  • Include Service Assurance?

• Will come back to TOC this week Oct 12 

• Mapping work in O-RAN WG1 (Disaggregated SMO) to related opensource projects 

  • Strawman for architecture - driven by some candidate usecase flows.

  • Aim for alignment across projects and across diff specs.

  • Aim for common vocabulary etc.

• @N.K. Shankaranarayanan working on slides now. See draft slides from previous weeks:
