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)Still trying to stabilise API for R1.

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

    • Fixed 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)

    • Fixing an issue with Service-ID (request param)  vs ClientID (in auth header) when creating an A1 Policy.

    • Updating to SpringBoot 3.3

    • Database-based persistent storage now enabled.

  • Service Manager

    • Hoping to discuss/demo (below) 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.

  • Release K Planning:

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

SIM (@Alex Stancu)

• Planning to demo Hybrid & Hierarchical OAM at F2f - including interesting issues like VES message translation.

  • Hybrid and Hierarchical OAM Architecture

  • Uses the new Python platform for O1 & OFH simulators

OAM (@Martin Skorupski)

• Working on wiki updates to update model links etc.

  • Discussion page: O-RAN YANG published in 2024-06 (awaiting WG5 WG10 clarifications)

    • Spotted some issues - See color-coding

    • Working on CRs for WG5 & WG10

• Working with @Alex Stancu on Hybrid and Hierarchical OAM Architecture (Above)

• Some feedback on OAM functions from IOS-MCN (Ref Meeting 2024-07-23 Meeting notes)

  • Will discuss next week.

• Also considering reports of issues & age of some it/dep deployment - esp OAM parts

AI/ML platform project (@subhash )

• Minutes & Meeting: Meeting notes

    • Services with path parameters - the format of the returned URL is in form http://domain.com/path1/{pathparam}/path3 etc - not with regular expressions

OSC Integration / INT (@fransiscus bimo )

• Minutes: https://lf-o-ran-sc.atlassian.net/wiki/display/IAT/Current+Meetings

    • Working to add support for grouping/collection in registry & api

    • Working to add tagging/classifiers/decorators to help markup & expressive retrieval of data from TEIV

    • Need to start working with others in OSC & beyond to help populate TEIV registry with data from their 'sources of truth'

    • Hope to make alot of use of TEIV in demos/rapps in K-Release

RSAC (@Rittwik Jana  @Martin Skorupski )

• Minutes: 2024 RSAC Meetings 

• No update this week

Questions / Comments / AOB:

• @Deena Mukundan

  • Question about CAPIF & Service Manager: How does an invoker update the list of Services/APIs it wants to invoke, after discovery.

    • @John Keeney (Ericsson EST) Current implementation assumes all Invokers (after registration) can discover all services. (Should be restricted to just the service they are allowed to invoke)

      • So currently, just go ahead and try access the service. Access to the service may then be locked by API Gateway of Service mesh, to enforce the Service Exposure.

      • CAPIF spec does not seem clear about how to do this.

    • @John Keeney (Ericsson EST) unlikely to work more on this in this release

      • Limited bandwidth
