OSC Project roundup:

News from OSC TOC call last week

• https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/#ORANSCTechnicalOversightCommittee(TOC)

  • Last week's TOC (Thursday):
    
    

    • OAI & OSC collaboration is making some progress

    • Discussion on a whitepaper for SWRBP for end-to-end use case (Super Wireless RAN BluePrint)

  • This week's TOC (in 2 days):

NONRTRIC (@John Keeney (Ericsson EST))

• Work ongoing - as per last week:
  
  

  • RAN PM functions - tidying up & re-releasing in maintenance release.

    • Working with AIMLFW project: @Joseph Thaliath to use newer versions

  • Making good progress on rApp manager. More in coming weeks

  • 3PP dependency updates & addressing vulnerability

  • 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 expressivity of docs etc.

  • Issue with test framwwork

    • underscore in URI hostnames - introduced by docker-compose (v1)

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

    • Further investigation needed re effects on A1-PMS/ICS & A1-SIM

SIM (@Alex Stancu)

• No major update

  • @Alex Stancu was away last week.

OAM (@Martin Skorupski)

• Looking at Netconf "Yang Schema Mount" for O-DU/O-RU relationship (WG5 yang models)

  • making some progress ... more to come

• Request (from RSAC) to make proposal for RAN PM streaming

  • See below

  • PM Streaming

• Working with team in T-Systems to update ONAP VES collector to work  with native kafka.

O-DU @Vidhu (Deactivated))

• No update this week

OSC Integration / INT (@James Li )

• Near-RT-RIC team today showed a demo of osc near-rtr-ric with an updated version of OAI DU/CU

  • To work with KPIMon xApp.

  • Hope to be able to reuse this work in ongoing OAI collaboration

SMO (@Seshu Kumar Mudiganti )

• Meeting notes Meeting notes

• No Update this week

RSAC (@David Kinsey [AT&T] @Rittwik Jana )

• No update this week

• Minutes: 2024 RSAC Meetings 

• Good discussion about I-Release plans, & how to report progress according to new streams/usecases. 

  • More to follow in coming RSAC & TOC calls.

  • Some concern about scope ambition vs resourcing ...

    • Maybe discuss at SMO call tomorrow?

PM Data Streaming (@Martin Skorupski  & All)

• (Recording timestamp @ 10:30)

• PM Streaming 

• O-RAN OAM spec refers to 3GPP specs to use websocket for transport

• Data serialisation format options presented by 3GPP:  Ref sect 11.5 TS 28.532

  • https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=3427 

    • https://www.3gpp.org/ftp/Specs/archive/28_series/28.532/28532-h30.zip

  • ASN1, or

  • GPB (preferred)

• Suggestion to do 3gpp-XML→yang→GPB  ...

• Refer to "establishStreamingConnection" operation, table 11.5.1.1.2 "streamInfoList" input parameter where PM stream job is defined

• But how will the SMO terminate streams, parse, and distribute the data?

  • Proposal

    • SMO needs a Websocket stream terminator (e.g. to: S3 bucket, or Kafka?)

    • SMO needs a GPB data parser (to: XML, or JSON?)

    • <a big gap - for further study>

      • Alot depends on the data characteristics & scalability concerns

    • Then re-use NONRTRIC RAN PM functions so rApps can subscribe to filtered PM data in JSON format in Kafka and/or InfluxDB

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

  • Need to read-up some more and come back to this in future weeks.

  • Need to clearly demonstrate if there is a benefit beyond file-based PM and/or streamed trace data.

    • e.g. shorter reporting period (ROP) file-based?

  • Very significant scalability challenges as reporting period decreases, network function increases, job count per function increases.

Questions / Comments / AOB:

• None this week.
