• 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.

AOB:

• A1 Query (Martin Skorupski)
  • Is A1 work in O-RAN stable/mature? 
    • John: Yes. Some work ongoing on tests.
      Also some additional work items (&proposal) under discussion. But no actionable output yet. 
      • Summary: Stable with little recent changes. 
        
        
• O2 IMS & FOCOM (Vishal Varvate)
  • Vishal Varvate's team are working in this area: 
    • Slack message: "Vishal and his team is available for  FOCOM to O2IMS Integration implementation work and team o-ran can provide feedback on whether they need any contribution or not."
    • So if anyone is interested in working in this are please ping Vishal Varvate & John Keeney (Ericsson EST)
      
      

• CVEs:

  • 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 NONRTRIC-1082 - Getting issue details... STATUS , INT-170 - Getting issue details... STATUS
    • 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 Parts of it are VERY out of date.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 (Ericsson EST)
      
      

• 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.
