• No update

• Topology & Inventory: (@John Keeney (Ericsson EST) :

  • Looking at how to build an adapter for O2 information to try populate CLOUD domain entities & relations - v. early stage.

Integration (@bimo fransiscus asisi)

• NONRTRIC team still talking with Bimo about an error starting an rApp. 

  • Really hope to get that solved very soon. We keep thinking we've solved it, but it keeps coming back. Will have a joint call to get it right. 
    
    

• Who to talk to about O2-Tacker work in SMO? 

  • See SMO meeting - every 2nd Tuesday

    • Ref: OSC SMO Project meeting notes

    • Ref https://lists.o-ran-sc.org/g/main/viewevent?repeatid=62687&eventid=2826509&calstart=2025-09-10 - every 2 weeks

    • Please cc @Martin Skorupski in emails if that would help.
      
      

• AI-ML-FW & Integration with SME / DME (@bimo fransiscus asisi & @John Keeney (Ericsson EST))

  • Any service can register / discover DME prouducers & consumers or DME types/producers/consumers - not just rApps. 

  • See Service manager API & ICS API. 
    
    

• SMO/NONRTRIC integration integration tests

  • @John Keeney (Ericsson EST) Still working on an stable install - ready soon (still working with @Matt Watkins for charts/scripts release GA job) 

  • ... soon. Then this will be a good reproducible base for tests. 
    
    

• Note ICS is not R1-DME compliant 

  • @Deena Mukundan @John Keeney (Ericsson EST) - No immediate plan to make ICS R1-DME spec compliant

    • Should not be too hard because its conceptually aligned - especially for stream/even-base data types/jobs. 

    • All help very welcome & badly needed

  • SME is much more compliant since it uses the CAPIF API

AOB:

• Github Actions / Workflows Migration (@Matt Watkins, @John Keeney (Ericsson EST), @Martin Skorupski):

  • Matt & Ravi making good progress on OAM GHA for container upload to nexus (permissions error? & previous issue with gerrit→github triggering) 

  • Still working on uploading / releasing it/dep helm charts/scripts for SMO Install  

• CVEs:

  • No update - need tool support/scanning for LF. Talking with @Sridhar Rao & @Matt Watkins

  • Proposal for discussion between PTLs & later approval from TOC: Discussion about updates of the parent CVE page 

  • Code not intended to be use in production should be tagged with a disclaimer in some way

  • Should be at a repo-level or directory level - suggest directory level.

  • Sample can be seen at https://gerrit.o-ran-sc.org/r/c/oam/+/14745

    • Merged.  

    • @John Keeney (Ericsson EST) added the human-readable parts to some NONRTRIC repos - but machine interpretable part still needs tool support, discussion & may change. 

      • e.g. https://gerrit.o-ran-sc.org/r/c/nonrtric/plt/rappmanager/+/14826 

    • @Sridhar Rao. @Martin Skorupski will discuss with @Matt Watkins & teams.  
      
      

• Would like to contribute (@Sri Venkata Naga Phanindra Akula)

  • Phanindra would like to contribute somewhere - maybe documentation initially? 

  • @John Keeney (Ericsson EST) - Could perhaps look at the current docs/guides for the integrated SMO, based on: 

    • Readmes / examples etc in https://gerrit.o-ran-sc.org/r/gitweb?p=it/dep.git;a=tree;f=smo-install 

    • Info in https://lf-o-ran-sc.atlassian.net/browse/NONRTRIC-1082, https://lf-o-ran-sc.atlassian.net/browse/INT-170

    • SMO Lite - An Integrated Open-Source SMO Deployment

  • Could also look at the overall OSC documentation. Parts of it are VERY out of date. 

    • https://docs.o-ran-sc.org/en/latest/

    • https://gerrit.o-ran-sc.org/r/gitweb?p=doc.git;a=tree

    • e.g. https://gerrit.o-ran-sc.org/r/c/doc/+/14709 
      
      

• Winlab servers (OSC Test lab) (@Martin Skorupski, @Ivan Seskar)

  • No Update this week.
    
    

• RANPM files for O-RUs (@Sridhar Rao)

  • O-RU File-based Performance Management

  • Will continue to look at this 

  • Question: is the schema for the file (CSV) defined yet? Anyone have a sample?

    • Based on - but not directly interpretable - from O-RAN Management Plane Specification v18.00 18.0 – LINK – Section 10.3.2 – File Upload

  • Parser will be very difficult. - Is there any point in pushing files to SMO that cannot be parsed? 

  • In hierarchical mode - the O-DU needs to parse data from O-RU to re-present it as O1

    • The format of the data from the O-RU may be similar to the OFMP-PM data sent to SMO in Hybrid mode ??? 

    • If so, how do O-DUs parse this? Anything available we can reuse? 

    • Sridhar will have a look in his wider community .... 

    • No update yet - but following up this week
      
      

• Sample rApp (@Sridhar Rao)

  • Experimenting with a sample rApp 

    • e.g. https://github.com/o-ran-sc/nonrtric-rapp-orufhrecovery/blob/master/scriptversion/app/main.py 

    • Would need to change to a proper yang model: 

      • https://forge.3gpp.org/rep/sa5/MnS/-/blob/Rel-18/yang-models/_3gpp-nr-nrm-rrmpolicy.yang?ref_type=heads

    • This 'rApp' is very old - and to be deprecated - e.g. does not include any of the 'current' rApp platform capabilities, SME DME, packaging, etc.. 

  • But a better starting point would be: 

    • Sample ESRApp

      • Discussion End-to-End Integration

      • rApp: https://github.com/o-ran-sc/nonrtric-plt-rappmanager/tree/master/sample-rapp-generator/es-demo-rapp

        • based on: 2025-06 O-RAN F2F Fukuoka#Demos - Demo at June 2025 F2F = Demo 2 - "Integrated SMO Deployment with rApp use Case"- See recording @30min

        • rApp is currently updated a little now https://gerrit.o-ran-sc.org/r/c/nonrtric/plt/rappmanager/+/14836 - Merged 

          • Use case is NOT practical for a real deployment - only intended to demonstrate a ML-enhanced closed-loop use case. 

        • Full integrated Platform flavor for the use case: https://gerrit.o-ran-sc.org/r/c/it/dep/+/14799 - Merged
          
          

• RANPM Install Questions (@subhash)

  • Older RANPM install doesn't seem to work with K8S version 1.32.3 (as recommended by Bimo in general platform install script) 

  • Strimzi version incompatibilty when installing older ranpm install scripts. 

  • Using it/dep smo-install version: Saul & Sridhar tested with K8S 1.32.3 - Aravindhan 1.32.7 

    • Suggest using smo-intsall scripts/charts with ranpm override/flavor

      • ./2-install-oran.sh ranpm

  • Need to deprecate older installs / guides etc. No longer supported. 

  • OK now? 

    • Thanks to @Aravindhan Ayyanathan
      
      

• Is there any test data in TEIV?  @Sridhar Rao

  • Yes. See unit tests & function tests. Some sample data can be found in the repo for those:

    • There is an option to pre-populate teiv with sample data using https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=blob;f=docker-compose/docker-compose.yml;h=ae9b20af4c5355c1a4682b9c6fae97d3bc6f8e25;hb=HEAD#l45

      • https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=tree;f=docker-compose/cloudEventProducer;hb=HEAD

  • Otherwise we need adapters to populate the data.

    • We only have a couple now

      • https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=tree;f=adapters;h=8216983a8e72f81e6a47fb7a67035cbc16dd7382;hb=HEAD

      • https://gerrit.o-ran-sc.org/r/gitweb?p=oam.git;a=tree;f=code/network-generator - using the 'teiv' output format to create a dump of cloudevents 

      • More adapters on the way this release. 

    • You can easily write new adapters / stubs by publishing to event interface: 

      • Create a cloudevent & publish it to kafka  - e.g. using https://cloudevents.github.io/sdk-java/kafka.html

      • https://docs.o-ran-sc.org/projects/o-ran-sc-smo-teiv/en/latest/discover-and-reconciliation-interface.html

      • https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=blob_plain;f=teiv/src/main/resources/v1/topology-exposure-inventory-kafka-asyncapi.yaml;hb=HEAD
        
        

• Any Sample RANPM consumer rApp?: (@Sunil N)

  • See Demo at Montreal: 

    • 2024-10 O-RAN F2F Montreal#2024-10O-RANF2FMontreal-8 

  • See sample DME consumer rApps (not RANPM)

    • https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/plt/rappmanager.git;a=tree;f=sample-rapp-generator/rapp-sample-ics-consumer;h=1d6f7ef7d422ed7ba40c8b63c903634a99a5a9e2;hb=refs/heads/master

    • https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/plt/rappmanager.git;a=tree;f=sample-rapp-generator/rapp-simple-ics-consumer;h=98fc0e90ce1feccd98d8dc9b2798d0b86c2cdeba;hb=refs/heads/master

    • These rApps should be extended to use the ICS/DME data-type produced by the PMProducer function in the RANPM toolchain

      • https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-ranpm/en/latest/pmproducer/index.html

      • Note: The specifics for the DME type produced by the PMProducer depends on how it is configured.
        Once PMProducer is running & available to produce data, suggest querying ICS to get more info on the Data type to help identify what the consumer needs to consume that data (create a job). 

  • See sample RANPM rApp at: 

    • https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/plt/ranpm.git;a=tree;f=pm-rapp;h=70f4fcdd4ebd3ae94407136a43d328fb6078af81;hb=HEAD

    • But this is just the docker image for the rApp uService. It would need to be adapted wrapped in an rApp and created using rApp Manager. 
      
      

• Who will use the services expose by rApps? (@Sunil N)

  • Other rApps.

    • e.g. if you have a collection of rApps working together. 

  • Can also be used to expose platform services from rApps.

    • But may not be a good idea - Platform services are probably not-transient like rApps.

    • Probably not a good idea to have platform services appear/disappear. 

    • SME currently does not different between platform services (SMOSs) & services provided by rApps. 

      • Once the Decoupled SMO concept matures, SME could be used for SMOS↔SMOS service exposure/discovery
        
        

• PRB utilization use case (rApp & ML) (@Sunil N)

  • Working with sample/sim data to train a model, then deploy as a rApp

  • Good use case to progress AIMLFW integration with rApp toolchain (@Sunil N, @subhash, @John Keeney (Ericsson EST)

    • Training, Model deployment & inference service LCM. 

      • e.g. would like to see different options for model & inference service containment & LCM - both 'inside/part-of' to rApp, or outside rApp using AIMLFW functions.
