NONRTRIC (@John Keeney (Ericsson EST))

• Thanks to @Sonia Sangari  (Moving to another area) Sorry to see you go

• Service Exposure Manager - Started - New function pulling together previous work

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

• Mostly same as last week:

  • Making good progress on rApp manager.
    
    

    • Adding support for DME integration now. Will demo again soon.

  • 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.

    • Completed for A1-PMS.

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

    • Investigations & testing ongoing

    • 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

    • 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.

SIM (@Alex Stancu)

• Solution ready for storing TIM's datasets - Thanks to LF team for help storing the data

  • https://nexus3.o-ran-sc.org/#browse/browse:datasets 

  • To support AIML project

  • Will update RSAC

OAM (@Martin Skorupski)

• O1 Demo for OAI functions at O-RAN F2F
  
  

  • Update to 3GPP yang model

  • Raise/Clear Alarm

ONAP Update (@N.K. Shankaranarayanan)

• No update this week

Round-up from F2F (@James Li )

• Lots of interest in working with OAI
  
  

  • O1 demo (@Martin Skorupski)

  • QoE in Near-RT-RIC xApp based on KPI data.

• Lots of people from related opensource communities

  • e.g. nephio want to work with OAI related to RAN functions (e.g. their R2 release)

  • e.g. Discussion about SMO with Nephio

    • Would like a panel discussion on related SMO work

• SCCL:

  • Making progress - and discussions ongoing

• OSFG

  • SWRBP: discussion on where to source function options & combinations & how to integrate

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

• 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)

SMO Deployment

• 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.

• Being discussed as part of ASFG SWRBP.

Disaggregated SMO Flows (@N.K. Shankaranarayanan)

• No update this week.

• 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:
