  • Last week's TOC (Thursday):

    • New Slack Channel:

      •  o-ran-sc-lf.slack.com 

      • Invitation: Will expire in 7 days: https://join.slack.com/t/o-ran-sc-lf/shared_invite/zt-2mvobo4yf-TvDf1IU8PiXCehQPiIbs1Q 

    • New logo

      • Sally / @Martin Skorupski Will make Logo source files available, e.g. somewhere on OSC wiki.
        
        

        Open

        

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

      • 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.

• 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

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

• No update this week - @Alex Stancu is on vacation 🌴
