Proposal: "Predict future PRB demand per slice in 5G RAN Network" (Sunil N)

• Sunil N Working on this now. Will revert via stack if there is any issue.
• Last week:
  

  • Sunil N presented some slides proposing a new use case & rApp for "PRB demand prediction - per slice"

    • Slides: ORAN_Proposal_Predict_Future_PRB_Demand_Per_Slice_In_5G.pptx

    • All: Looks great. Looking forward to getting stated.

    • rApp & deployment will be very similar to AIML rApp demos at 2024-10 O-RAN F2F Montreal 

      • See also Energy Saving rApp usecase for another sample.

    • Will start with dummy data. for training 

    • Will work with subhash for training etc & how to store trained model 

  • Action: John Keeney (Ericsson EST) to propose a new repo to store rApps 

    • larger/ongoing rApps may be promoted to own repo later

    • (Need to remove existing old/obsolete rApp from many years ago!)

  • Action: Sunil N Aim to create a wiki page for the use case, to store snippets, discussions etc for future users & other rApps developers

    • Also discuss on mailing list and/or slack as needed. (Slack invite)

  • Action: Sunil N & Martin Skorupski To briefly present & then track use case in RSAC. 

How to access Winlab servers (Martin Skorupski, Ivan Seskar)

• Plan for 8 servers - will look something like this:

How to add PM data to InfluxDB (Demond Wael)

• No update
• Last week:
  
  • Hello to Aya Kamal Elbakly, Demond Wael, Mina Akram, Ziad Hossam (Orange Innovation Egypt) 👋
  • Difficult to inject data into RANPM pipeline to have it appear in InfluxDB
  • Suggest try latest version of SMO install (inclund RANPM functions from it/dep)
    
    • Need to build https-server & ranpm-raap locally - they are not "released" 
  • Need to ensure data ingested is in 3GPP PM file format & PM Producer filter is configured to match data.
    
    • Check logs 
  • Working on a CSV → 3GPP file format - overlaps with work in Energy Saving rApp usecase to convert Viavi-format CSV → 3GPP XML file format
  • From last week & again this week:
    
    • John Keeney (Ericsson EST) Avoid trying to use internal interfaces/formats/topics in the RANPM flow
      
      • Use 3GPP XML files, hosted in some FTP/HTTP server (HTTP server provided), then send a VES event to VES collector (with the path/filename to the new file)
        • Toolchain does all necessary XML→JSON translation, filtering etc, then inject into InfluxDB)
      • Ref: https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-ranpm/en/latest/overview.html#data-flow 
      • latest snapshot version of RANPM functions support 3GPP file-ready event format & latest NR PM data files. Older (Release K) versions only support older VES-format file-ready events & older 4G PM data file.
        
        • Older version demo: 2023-08-22 Meeting notes - Joint OAM / NONRTRIC / SIM Community meeting#20230822MeetingnotesJointOAM/NONRTRIC/SIMCommunitymeeting-DemoNONRTRICRANPMFunction-Dockercompose&Scripts()
      • For debug/support please send an email, or use slack (Slack invite)
  • Usecase is energy saving also
    • Lets work togther on related rApps / use cases
      • Ref: Sunil's presentation above
      • Ref: Discussion End-to-End Integration
  • Action: Sunil N Will check with Orange if possible to create a wiki page for the use case, to store snippets, discussions etc for future users & other rApps developers

RSAC Energy Saving integration use case  (rApps & AI/ML)

• No update this week - but working away on this.
• Plan to be used to varying degrees in several venues over the next months
  
  • OAI workshop (21-22 May)
  • OSFG workshop (23 May)
  • June O-RAN F2F - Fukuoka (2-6 June)
• From last week:
  
  • Discussion End-to-End Integration
    • Good progress made on O1-PM - convert to file format & reuse existing RANPM functions → rApp
      • Note: RANPM snapshot images have timed out. !
        
        • John Keeney (Ericsson EST) & Aravindhan Ayyanathan (Ericsson EST) - Recreate the snapshots. Good for another 30 days
        • Make sure release happens before 30 days & update charts in it/dep
    • O1-CM: 
      • When integrated SMO deployment is ready rApp should be able to use NCMP as a wrapper for RestConf → SDNC/ODL
      • Exposed via SME to rApp
    • Topology:
      
      • Martin Skorupski will create a topology/deployment model - which can then be processed by TEIV to bootstrap the TEIV topology.
        
        • Will help pre-populate the topology & add links etc - where adapters do not yet exist.
      • Also TEIV adapter nearly complete; to poll NCMP/SDNC to populate TEIV-OAM data of ODUs/OCU/ODUCell/OCUCell
        • Available for rApp to query which DU/Cells to target for Energy saving rather than hard coding
      • TEIV can then be queried by ESrApp to get IDs etc & containment info needed - rather than hardcoding in rApp logic
    • AIML
      • John Keeney (Ericsson EST) & subhash to discuss: 
        • How & when training happens, & where trained model is stored
        • How AIMLFW is deployed as part of SMO
        • How rApps ML model is deployed as an Inference service for rApp to use (KServe) 
    • rApps & xApp
      • bimo fransiscus asisi to advise on where the current Apps are - to help identify how to extend for deployment. 
    • VES collector in SMO
      • Can change configuration in integrated SMO (via configmaps - TBC), but need to download & make 3GPP schema files available somehow.
        
        • May need to add a custom step to pull these files during SMO setup. (Similar for other functions where spec downloads might be required before use)
    • Will discuss more with fransiscus bimo during RSAC
      

OAM (Martin Skorupski)

• No major update this week:
• Still  working on deployment - currently still docker-compose
• Will update info on labs - e.g. now obsolete UNH-IOL & OpenWirelessLab.

• JIRA:
  

  • OAM-429 - Getting issue details... STATUS

NONRTRIC (John Keeney (Ericsson EST))

• Working hard on Integrated SMO deployment
  • First version nearly ready for testing.
    • Working hard on Nephio/ONAP/OSC co-location. 
    • Needs alot of resources - happy to see winlab machines coming on line.
    • Still have a networking issue between nephio control cluster (native k8s) & nephio workload clusters (kind k8s) to deploy OAI nodes
    • Next steps will include AI/ML platform integration
      
      • To support ML inference service LCM via AIMLFW (as well as rApp manager)
      • To help demonstrate training & model management etc too
• Working on ES-rApp & use case - mainly as a requirements driver for platform. Lots to do!
  
  • Need a sample ML model for a bootstrap/test inference service
