    • Update about OAI/OSC/OSFG workshop

    • Update from @Alex Stancu about Energy Savings use case (link)

    • No Update from @Seshu Kumar Mudiganti on SMO & Orchestration - Maybe next week ?

    • All PTLs should update wikis & start ORAN Spec compliance

  • This week's TOC (in 2 days):

    • Maybe not happening this week? Thanksgiving Day in US? No update in calendar yet (https://lists.o-ran-sc.org/g/main/calendar)

    • Update expected from @Seshu Kumar Mudiganti & @N.K. Shankaranarayanan on SMO-related activities

  • OSFG ... Time stabilizing to Monday 5AM PST - but watch O-RAN Alliance Calendar.

• Service Exposure Manager - Started - New function pulling together previous work. Unlikely to deliver in this release

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

  • A1 & R1-A1 in good state right now.

    • Will continue to make small changes as needed.

    • Working on how to describe outgoing calls

  • R1-DME will likely need alot of work as R1-DME specs mature

  • R1-SME interface being defined as part of "Service Exposure Manager" (above).

• Making good progress on rApp manager.

  • Adding support for DME integration now.

  • Hope to demo in 2 weeks

• OpenAPI-first in A1-PMS & ICS

  • A1-PMS changes in ONAP CCSDK/oran merged now

  • ICS still to do.

• Pairwise test A1 Policy functions in near-RT-RIC & NONRTRIC

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

    • Working fine in our function tests,

  • Working on Pairwise test for Integration environment -

    • Will need help from @James Li  (email) 

    • Add A1-PMS & maybe a A1 SIM to near-RT-RIC deployment ? add in some NONRTRIC A1 functions?

    • Current xApp deployed (KPIMon Go) does not use A1 Policies - so we need an A1-enabled xApp to be added

      • @James Li & @naman.gupta might be able to help. Hello-World xApp should be OK, or Traffic Steering?

• ONF have a deployed near-RT-RIC. Should consider this for pairwise testing too. (For traffic steering)

• O-RAN "planning" tool to visualise & deploy a RAN, and populate topology & inventory

  • Ongoing

  • Now supports handover areas between cells.

  • 1x 5G Core per SMO

• @Alex Stancu @Martin Skorupski - Need to check what version of VES collector we us in IT/DEP & tests. May not be the latest (not sure if O1 PNFRegistration is supported)

• Will be working with Bimo about work in Taiwan Lab - some testing also happening there.

  • @fransiscus bimo Working to generate dataset of Energy Saving use case

  • @fransiscus bimo making progress on the rApp - but work to do about how to describe/package/manage the rApp

    • Will see NONRTRIC rApp Manager Demo below.

    • Working on some sample flows  -Would be good to keep in touch with @N.K. Shankaranarayanan - who is assembling SMO-related workflows.

• Makes a lot of use of ONAP ACM to support rApps that contain a composition of K8s microservices, ML Models, Policies, Workflows, Configuration, A1 Policy, etc

  • Multiple rApp instances for rApp types

  • rApp is Lifecycle Managed as a single composition of App elements

    • Different Element types are handled by pluggable 'Participants'/Handlers

      • Current Participants: K8s/Helm, A1 policy, ONAP Policy, KServe (ML), HTTP configurator, DME, others

• Adds Service Management & Exposure - SME    (Not already supported in ACM)

  • All produced & Consumed services are described in App package, so Service Registration & Service Discovery needs to be handled.

  • Uses NONRTRIC CAPIF Core function

  • R1-SME aligned

• Add Data Management & Exposure - DME    (Not already supported in ACM) 

  • All produced & consumed Data Types are described in App package, so Data Producer Registration & Data Type Discovery & Data Job creation needs to be handled. 

  • Uses NONRTRIC Information Coordinator Service

  • Similar to R1-DME

• Prototype rApp Package presented - Not yet Stable!

• rApps, rApp instances have well-defined state models

• Call sequences for various rApp & rApp Instance workflows presented.

• Demo:

  • Show a sample rApp package

  • Deploy & prime the rApp

  • Create one instance - showing all its constituent parts configured, started & running. Service & Data types registed & discovered, Data Jobs created.

  • Delete the created instance - showing all its constituent parts stopped & removed

  • Delete the rApp & its definition - showing rApp environment cleaned up

• None this week.
