OSC Project roundup:

News from OSC TOC call last week

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

  • Last week's TOC (Thursday):

    • No call last week

    • Discussion at O-RAN F2F meetings:

      • F2F Presentation Material

      • H Release 

  • This week's TOC (Tomorrow):

    • Discussion on copyright & O-RAN F2F preparation

NONRTRIC (@John Keeney (Ericsson EST))

• Goodbye to @Henrik Andersson one of our first & most prolific contributors for the past 4 years. He'll be missed

• G Maintenance Release - small bug fixes etc

  • Image preparation & releases completed.  No very significant updates from G Release

• File-based PM data → InfluxDB

  • Early demo at AI-MLProject this week
    
    

    • https://gerrit.o-ran-sc.org/r/c/nonrtric/+/10477

  • Will demo here in coming weeks when a little more stable

  • Uses tool-chain demonstrated for file-based PM parse filtered & streamed to rApps - now extended to also store in influxDB.

    • G-Release: Demonstration: "PM Collection & Delivery to rApps" Demo
      
      

• Inference Services in rApps

  • Extension to ONAP ACM functions - added a 'KServe Participant'

  • Now supports ML Inference services in ACM Apps (rApps) - so they are LCM'ed in a common way - along with other rApps components/elements

  • Will demo in a short while when function is a bit more stable / cleaner.

  • https://gerrit.onap.org/r/c/policy/clamp/+/133263

  • https://docs.onap.org/projects/onap-policy-parent/en/latest/clamp/clamp.html

  • https://wiki.onap.org/display/DW/Automation+Composition+Management%3A+Architecture+and+Design

• Otherwise as per last week. Development for each of the topics below continue ... 

  • Release H Planning continues:

    • (R1) Service Exposure & Management

      • CAPIF Aligned Service Registry

      • Secured/Sandbox execution environment

      • Controlled access & exposure of service to/from rApps

    • (R1) Data Management & Exposure

      • Previous focus on PM data - but will extend to other use cases too

      • Aim to work with AIML project for Training (and Inference ?) data access

    • rApp Management

      • Built on ONAP “Automation Composition” model & platform to implement rApp use cases

        • rApp-specific extensions needed

      • Packaging, Onboarding & Orchestration of rApps

        • rApp-specific packaging & Onboarding

          • Aim to align with / inform ongoing work in O-RAN (& OSC) about Common App packaging & Onboarding.

        • (rApps with & without µService)

      • Overlap with Service Exposure work to examine role of an rApp Manager to support controlled exposure & LCM of µService and non-µService parts of an rApp

    • Continued A1-Policy & A1-Enrichment-Information evolution (& R1-A1)

      • A1 Spec evolution

      • A1-Policy work in ONAP (continues in ONAP London) - candidate for R1-A1(P)

      • A1-EI management as part of DME - candidate for how to include A1-EI in R1-DME

    • Sample use cases (rApps)

      • Requirements Drivers for rApp/R1 development

      • High degree of cross-project integration activity

    • Testing, Maintenance & Housekeeping

      • Function Test & Integration Test environment,

      • Support integration, deployment & configuration of SMO/Non-RT-RIC related functions & usecases in OSC Integration env.

      • Project coordination, Documentation, Delivery, Reporting, Cross-project alignment, Community demos, O-RAN Standardization support, etc.

SIM (@Alex Stancu)

• Continuing discussions with Northeastern Univ re ns3 simulator plugin - E2 Alignment

• Looking at ves File Ready event, to be O1 compliant

  • @John Keeney (Ericsson EST) @Alex Stancu We should talk about linking up & demoing O1-Simulator → rApp flow mentioned in NONRTRIC section above.

    • Could look at extending simulator to continuously/periodly expose PM files. ... But need some samples ... maybe with random data?

  • Some discussion on sample PM files ... Does anyone know where we could find an O-RAN O1 compliant sample file?

    • Still compliant with 3GPP DU/CU ... Maybe an operator might have a some samples

OAM (@Martin Skorupski)

• Updating OAM with latest O1 specs.

O-DU (@Hariom Gupta @Vidhu (Deactivated))

• No Update

OSC Integration / INT (@James Li )

• Working on XTesting for xApp onboarding etc

• Examining how to work with INF project re O2 interface, & overlap with Tacker team in SMO.
