OSC Project roundup:

News from OSC TOC call last week

NONRTRIC (@John Keeney (Ericsson EST))

  • Release G completed before Christmas/New Year break.

  • Release H Planning continues:

    • (R1) Service Exposure & Management

      • CAPIF Aligned Service Registry

      • Secured/Sandbox execution environment

      • Controlled access & exposure of service to/from rApps

    • (R1) Data Management & Exposure

      • Previous focus on PM data - but will extend to other use cases too

      • Aim to work with AIML project for Training (and Inference ?) data access

    • rApp Management

      • Built on ONAP “Automation Composition” model & platform to implement rApp use cases

        • rApp-specific extensions needed

      • Packaging, Onboarding & Orchestration of rApps

        • rApp-specific packaging & Onboarding

          • Aim to align with / inform ongoing work in O-RAN (& OSC) about Common App packaging & Onboarding.

        • (rApps with & without µService)

      • Overlap with Service Exposure work to examine role of an rApp Manager to support controlled exposure & LCM of µService and non-µService parts of an rApp

    • Continued A1-Policy & A1-Enrichment-Information evolution (& R1-A1)

      • A1 Spec evolution

      • A1-Policy work in ONAP (continues in ONAP London) - candidate for R1-A1(P)

      • A1-EI management as part of DME - candidate for how to include A1-EI in R1-DME

    • Sample use cases (rApps)

      • Requirements Drivers for rApp/R1 development

      • High degree of cross-project integration activity

    • Testing, Maintenance & Housekeeping

      • Function Test & Integration Test environment,

      • Support integration, deployment & configuration of SMO/Non-RT-RIC related functions & usecases in OSC Integration env.

      • Project coordination, Documentation, Delivery, Reporting, Cross-project alignment, Community demos, O-RAN Standardization support, etc.

SIM (@Alex Stancu)

  • Still working on OSC H Release Planning

OAM (@Martin Skorupski)

  • Looking at OAM Specs from O-RAN Alliance & 3GPP REL 18

    • e.g. Updating VES stddefined support etc, new versions of SDNR etc. 

O-DU (@Hariom Gupta @Vidhu (Deactivated))

  • No Update

OSC Integration / INT (@James Li )

  • Plan to use XTesting integration tests with INF project (esp for O2)

RSAC/SMO (@David Kinsey [AT&T])

  • Ref: 2024 RSAC Meetings

  • Update from AIML project re Release H plans

    • Included discussion on overlap/alignment/integration opportunities with NONRTRIC, SMO, Near-RT-RIC, RICAPPs, OAM projects.

  • Update from O-DU HIgh project re Release H plans

  • Update from SMO Tacker project re Release H plans

  • OSC/ONAP 

    • Mentioned this meeting - Unfortunately @David Kinsey [AT&T] cannot attend today - meeting clash.

  • Upcoming Open RAN workshop

AI/ML platform project ()

ONAP Use cases (@N.K. Shankaranarayanan)

  • No time for an update this week

ONAP / OSC / O-RAN Alliance: Cooperation & Alignment

Discussion: ONAP TSC Would like to better formalize relations between ONAP & O-RAN SC, and ONAP & O-RAN Alliance

  • @00:13:00 in Recording

  • Pawel, @Magnus Buhrgard, Bob, @N.K. Shankaranarayanan 

  • Also trying to establish a snapshot of interactions currently

  • How to improve cooperation

  • Goal: Avoid fragmentation, improve synergy, avoid duplication, raise awareness

  • (Unfortunately .. (or fortunately) ONAP TSC & OSC TOC calls are at the same time)

  • Areas being considered in ONAP: Is there a need to streamline requirements gathering process & cadence, release processes & cadence, integrated platforms vs services, using licensed specs

    • Same considerations could be looked at in OSC too - to have a 2-way flow of awareness, requirements, software,

    • For example, there can be a very significant lag between a requirement becoming obvious in one project, and released software being available in the other ... often Many months.

      • Rule of thumb: A project should only use 'released' software from other communities

      • It would be better to have a much more flexible, continuous, faster cadence of requirements planning & interim or continuous software releases. (while also keeping the periodic Major Release time scales)

  • Would be good to have better cooperation between specification work & implementation (pre-spec & post-spec)

    • Note: Any project - not just OSC - including ONAP - can consume/feedback to O-RAN Alliance on a equal basis

      • Would be good to better understand if/what 'special relationship' between OSC & O-RAN Alliance. No blocker exists to other projects.

    • O-RAN Licensing remains an issue for all opensource projects - including ONAP & OSC

  • Some topics where there is a clear interaction ONAP/OSC - and alignment would be beneficial:

    • release cadence

    • non-rt-ric / smo

    • rapps

    • oam

    • orchestration and cloud

    • simulator (O-CU, O-DU, O-RU)

    • use cases alignment 

    • integration

    • license issues

  • Potential actions

Questions / Comments / AOB:

  • Follow up Note on opensource/specification alignment: :

    • @Magnus Buhrgard, @Martin Skorupski, @John Keeney (Ericsson EST)  

      • Would be good to have a separate discussion about how opensource and specification activities could benefit each other better if there was better interactions.

      • O-RAN Alliance seems like a particularly good candidate to examine this

      • Lets discuss this further in another call.

  • No more time this week
