OSC Project roundup:

News from OSC TOC & OSFG calls last week

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

  • Last week's TOC (Thursday):

    • Talk from @fransiscus bimo about plans for the Integration project.

    • OSC and ONAP wikis will move to a centrally located/hosed Confluence site (atlassian.net)

      • On hold pending some issues 

      • Possible issues:

        • Links will break, esp cross-site links (where full url is given - e.g. last week's meeting minutes page urls: https://wiki.onap.org/pages/viewpage.action?pageId=231407794 & https://wiki.o-ran-sc.org/pages/viewpage.action?pageId=125043203)

        • User accounts need to be mapped or re-created on Atlassian cloud site - and people may already have accounts there that are difficult to map to LF-ID etc.

        • It is likely that recordings/ demos/ presentations / documents etc stored in current wiki may become unavailable?

      • Hopefully LF will be able to work around some of these issues.

      • Will wait for some feedback from other first mover projects to see how they went. Will hopefully answer some concerns then,

  • This week's TOC (in 2 days):

    • No major topic planned yet (AFAIK)

• OSFG:

  • Cancelled this week.

  • Moving into a summer break. Next meeting August 12.

  • Will discuss demos for next F2F.

    • Want more demos - similar to request from OSC TOC

    • Will look at several projects, e.g. OSC, SRSRAN, OAI, nephio, and lots of others

    • Would like to maybe align demos etc ...

  • No update on whitepaper, or when/if it might be published.

NONRTRIC (@John Keeney (Ericsson EST))

• Still working away on issue from previous weeks:

  •  A1-Controller

    • NBI Issues: Last Week WG2 R1 spec for Nov release changes from March version (not backwards-compatible)

      • May pull/remove the recent ONAP New Delhi & OSC J-Release versions of A1-Policy Management Service - which implements the Mar'24 version of the spec.

      • Will move direct to July Train version - currently been voted on in O-RAN Alliance WG2 as Maintenance-/ Bug-Fix-Release in next few weeks.

      • Do not want to support a version that has only been released for a couple of weeks then immediately deprecated.

      • May cause disruption to users that have already adopted the New-Delhi or J-Release versions

    • Fixing a bug in A1-PMS in ONAP & OSC - Where 'transient' Policies were being deleted when a service is deleted.

      • Fix available & preparing tests & patch releases for ONAP (London, Montreal, New-Delhi) & OSC (J at least & hopefully older)

  • Service Manager

    • Still working on adding boot-strap service exposures at SMO start-up - but its proving a bit more difficult than expected.

    • Manual registration via API is still working fine - but currently all Services need to be explicitly registered rather than auto-registered.

    • Hope to have a working solution soon.

  • Still Working to improve API documentation generation from OpenAPI defns.

  • Release K Planning:

    • No major update this week ... but will continue with more focus on demonstrators - esp aiming towards next F2F

• @subhash Hope to get started soon on integrated demo with AIMLFW & NONRTRIC

  • Would like to start drafting some wiki content.

  • Can discuss more this week - and more discussion at RSAC next week.

• @subhash & @naman.gupta Wondering about deploying NONRTRIC function using Nephio/Operator-based approach

  • Not sure why/how to use Nephio for SMO function deployment - instead focus is on RAN functions from NFO/FOCOM.

  • Will discuss further and give more detail on proposed approach

  • Would be good to hook up with @fransiscus bimo on plans for deploying SMO functions (and RAN functions)

SIM (@Alex Stancu)

• No major update this week

• Working away on existing items

OAM (@Martin Skorupski)
