  • Energy saving use case:

    • Discussion End-to-End Integration

      • see below ...

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

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

  • Slides:
    

  • 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 add PM data to InfluxDB (Demond Wael)

• 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 use case  (rApps & AI/ML)

• No update this week - but working away on this.

• 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 - 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 

Accessing WINLAB resources: @Ivan Seskar @John Keeney (Ericsson EST) @Aravindhan Ayyanathan

• @John Keeney (Ericsson EST) & @Aravindhan Ayyanathan now have access 

• Hopefully later in week will have a cluster of some machines in Lab

  • Ideally would like some ideas about how to structure deploy

    • e.g. into 2 deployments - for stable version & dev/scratch version

  • Needs some coordination

    • ... e.g. if you break it then fix it, or wipe & re-instate.

    • How often to auto-wipe/kill the deployments, etc.

  • lets see what is aviallable first, then we can discuss options.

OAM (@Martin Skorupski)

• No update this week:

• JIRA:

  • https://lf-o-ran-sc.atlassian.net/browse/OAM-429

NONRTRIC (@John Keeney (Ericsson EST))

• Working hard on Integrated SMO deployment

  • First version nearly ready for testing.

• No other update this week

• See previous weeks:

  • Updating ONAP A1-Controller

    • https://gerrit.onap.org/r/q/project:ccsdk%25252Foran

    • https://lf-onap.atlassian.net/wiki/spaces/DW/pages/129957892/O-RAN+A1+Policies+in+ONAP+Paris

  • Working on SMO Deployment

    • Combined lots of existing charts - now working together (ONAP, NONRTRIC, RANPM, TEIV) 

      • Alot of work needed to have all previous deployments using same underlying common functions - esp Kafka.

      • Current work in progress : https://gerrit.o-ran-sc.org/r/c/it/dep/+/14289

      • Need to document this better - wiki page, Jira etc.

    • Will try add Nephio later

    • Need to examine to integrate AIMLFW charts https://gerrit.o-ran-sc.org/r/gitweb?p=aiml-fw%2Faimlfw-dep.git;a=summary 

    • Also need to consider how to include existing SMO project functions e.g. Tacker

    • Will Services be available outside (@Sridhar Rao, @Aravindhan Ayyanathan)? 

      • Inside cluster all services can now use FQDN - not node-ports.

      • Services should also be register in Service Exposure Manager to be used via API gateway & discoverable

      • Eventually services may be discoverable / exposed outside cluster - e.g. ref CAMARA etc.
