  •  A1-Controller

    • Finally got several changes merged, and now need to do service releases in ONAP and OSC.

  • 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.

  • Getting started on sample rApps ... starting now

    • First ones will include AIML use cases. See below.

  • Working with AIML team to get platform integrated for QOE E2E demo. See below.

• No specific update

  • Working with @Martin Skorupski to prepare demo videos for F2F

• Topology & Inventory: (@John Keeney (Ericsson EST) :

  • Met with @Martin Skorupski about maybe integrating some additional topology information in TEIV & integrating with existing models

    • O-RAN-SC OAM Topology (Not an "O-RAN topolgy" - used by OAM project for network/deployment generation

    • Alot of extra infomation that may not be needed for a TEIV view - will examine overlap and/or transformation between models

    • Missing some key concept in current TEIV models, e.g. connections, interfaces, smo entities.

  • Working on a sample rApp to demonstrate TEIV

  • Will be adding new models ASAP - with clear O-RAN aligned RAN model (e.g. remove 4G & integrated gNB)

  • From Last week - Still ongoing

    • 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
