      1. Hi TOC members,

         Please prioritise the request below. Thanks Jack for your previous reply.

         Thanks,

         John

         Sent: Wednesday 26 February 2020 13:25
         Subject: Repo Request - portal/nonrtric-controlpanel

         Hi TOC members

         We agreed at last week’s TOC meeting to permit creation of a GUI for the NONRTRIC function. Thank you.

         But we also decided that it  would be ok to change the name, however LF will very likely require the name to be included in the official approval.

         So I am re-submitting the request with a new name “portal/nonrtric-controlpanel”

         I would like to request the following new repo:

         1. Proposed repository name: “portal/nonrtric-controlpanel”
         2. License: Apache 2 
         3. A brief description: This repo will be used for the NONRTRIC GUI – for visualising and manipulating NONRTRIC concepts such as A1 Policies/PolicyTypes supported in RAN, R-APPs, etc.
         4. A list of initial committers:
            a)  John Keeney, John.Keeney@... , lfid: JohnKeeney
            b) Patrik Buhr, patrik.buhr@... , lfid: PatrikBuhr

         Note: NONRTRIC GUI  functionality already exists in nonrtric repo. This new repo will be the new home for this.

         Thank you in advance

         John Keeney

      1. We put in a request for a talk.
      2. Tracy: Ericsson, Nokia, Samsung and Comscope with AT&T person as a moderator.  We submitted a request for a panel discussion.  Will discuss lessons learned and cross activities.  Proposal references O-RAN SC.
         1. Jinri - Companies who are had demonstrations MWC can submit their demos to the website.  Action / Jinri Huang work with Farheen to add to events.
         2. Jinri - We had planned lots of items for discussion.  We only scheduled two days plus one joint session with WG1.  We have a lot of items to discuss.  the original plan is to do this week.  We want to hold it off until next week.  
            1. project report from each PTL lasting 10 - 20 minutes.
            2. Collaboration discussion from OAI.
         3. Can we take next Tuesday, Thursday, and Friday the same time as TOC?  We don't expect too much participation with O-RAN WGs.  8:30 - 9 EST.
         4. If we have our regular meeting on a Wednesday we will have to use 4 days in a row.  Instead let's dedicate this time slot.
            1. Lusheng - Demonstrations have to be scheduled.
            2. Jack - Let's use next week to address the critical items.  We will skip the TOC for one meeting.  Let's get the most productive items in the time frame rather than have too many meetings in one week.  Let us figure out the most effective way.
            3. Rittwik - You can use the RSAC timeslot.
      3. John Keeney  is considering an Ericsson for a brief non real time RIC demo.  Tracy will share the details.
7. Status of Open Action Items (Old Business)
   1. Action/ Rittwik and Viavi.
      1. contributions for the test and emulator lab.  After checking internally with the team they will report back next week.  Licensing and cost.  Jack or Jinri viewpoints?
      2. Jack - Funding is an option but we'll have to ask for additional funding.  The question is how much and whats the value to us.  Whatever we invest in is effectively used by the community.  They want it set up in a community friendly cloud.  Could it be a yearly agreement hosted in the cloud and managed by the integration and test team.  Let's see what the best terms and conditions we can get for the software community to accomplish our goals.  We should ask everyone to comment.  Action/ user-59b16 start an email chain .
      3. Rittwik - slides are on the RSAC meetings page.
      4. Tracy - Not sure if O-RAN SC and O-RAN testing labs will share lab facilities.
   2. Jinri wants to discuss F2F. 
   3. Action / Farheen Cefalu update the Events page with the updated virtual meetings.
   4. Action / Jinri Huang wants to discuss the Open Data Set .
      1. Big data will be useful for Ai/ML and test.  O-RAN TSC set up a project to open data set.  LF open data set has 3 projects set up regarding opening of data.  What is the mechanism to open data?  LF has already developed an agreement specifying the regulations that we need to comply.  Community data license agreement has been created.
      2. This CDLA has been written into our SC charter.  We can open projects using the CDLA in the O-RAN SC.
      3. China Mobile wants to propose opening the CDLA.  This is a brief introduction.  Action/ Jinri Huang will shared slides to set up projects using the SC.
         1. Jack - we need to form a working activity to spend time talking and thinking it through.  The data is always a rich place for discussions.  The TOC doesn't have enough time to work it out.  We need to report back to TSC what our plans and goals are starting this new effort.  We should go through a process and talk to people and we're doing it right. 
         2. Jinri will provide materials and seek comments.
         3. We should form a spot here of where to put the materials and have the discussion.  Create the TOC on the left side of the tree to give the community a time to participate.
         4. Jinri will use RSAC time to review.
   5. Action/ user-59b16 update TSC with the short/long term UE emulator support.  
   6. Action/ TOC we need a test coordinator with the O-RAN test group so we can come up with a common plan between the test groups.
      1. David (DT) will reach out to someone he knows and let the TOC know next week. 
      2. William DIEGO  will talk to the focus group.
         1. 4 timeslots for this focus group and they are working on different documentations.  I didn't have time last week to introduce myself.  This afternoon I will introduce myself and be part of a link.
         2. Lusheng - we have software called OTF open test framework.  We are using it for the ETE flows for the health-check.
         3. Jack - Let us figure out how to collaborate.  We'll leave it to you and David.
         4. Zhimin Yuan raised a concern about the ODU Low and test.  Jack instructed Zhimin to work with Lusheng to address their hardware requirements needs.
         5. Lusheng - Zhimin's ask is beyond test but also the building on the platform.
            1. Actually it is software.
            2. Action/ Lusheng follow up with Zhimin offline to set up target architecture for ODU Low.
   7. Action/ user-a934b provide a list of functionality that O-CU plans on targeting of where the O-CU is going in the coming releases.
      1. Raised issue with aligning.
      2. Jinri - we conveyed this information twice during WG and TSC sessions.  The WG co-chairs have taken this message.  One is WG2 and WG3 we adjusted the timeline with Cherry and D release.

      4. Action/ user-a934b work with Lusheng to create the test cases.
   8. Community asked for a release manager.  
      1. We have a request out to the LF for some support on this.  Trishan - will have a discussion with David Mc Bride.  Action/ Trishan de Lanerolle set up a call with Jack and David.
   9. Action/ PTLs be prepared to discuss Bronze development sprint 1 demos.
      1. Lusheng will organize the end of sprint demos.
      2. Jack after ever sprint we have demos to reflect the items completed.

      4. Trishan - There is a +2 process.  
      5. Lusheng we want to have the +2 process an not allow the contributor to merge.
