4. Review of Today's Agenda

   1. John-Paul We would like to nominate John Keeney as the alternative contact for Ericsson.
   2. Martin has a request open for a repo and would like to discuss the Cherry release.

5. Release Votes and Approval

   1. Martin Skorupski adding a repo for TR-69.  
   2. Martin: We developed an adaptor.  We have 3 approvals we need 5.
   3. Action/ TOC members approve Martin's email for a repo request.
   4. Jack: Is TR-69 RU or DU?
      1. Tracy: The notion here is that since TR-069 Broadband's CPE planned management protocol 3GPP standard we are referring to an TR-069 adaptor to integrate into the O-RAN architecture. Most indoor / outdoor are speaking this TR-069 small cell solutions.  Not just Com-scope.  This complies with all 5G TR-069 communications.  This is the universal adaptor for this so all will interface.  It is operator selectable.  Some will select TR-069 others will use the O-RAN interface. 
      2. Jack: Is Com-scope getting proper credit.
      3. Martin: They are contributing the code and I will make sure they are aligned with all Linux Foundation licenses and will make sure they get the credit.
      4. Jack: Is TR-069 approved as an option under release?
      5. Tracy: This is coming under the O-RAN specification.  It will be included with multiple data models.  The TR-61 will be in the modeling specification.
      6. Martin: It was adapted by 3GPP and WG1.  They want to align their modeling topics with 3GPP.  It fits into O-RAN.  
      7. Jack: This is good it touches the aspect of touching networks and getting them going.
      8. Ganesh: Is this related to the data models?  This supports multi data models.  Which data models?
      9. Martin: TR-96 and TR-181. 
      10. Tracy:  If interested the first and global plugfest slides are on the O-RAN wiki.  I'll send the link in the chat.  Their demo is in the O-RAN virtual information.
          1. CHAT: From Tracy van Brakle (AT&T - WG1) to Everyone: (08:17 AM)

thanks William you are fast! appreciate it
      11. Jack: This covers the small cell items but the CU and DU will be under the O1 specifications.
      12. Marin: Yes
      13. Jack: TSC had a vote on approving Intel binary usage as part of the DU Low.  The vote closed last Friday.  It got only positive votes.  I sent a note to Zbynek who is the project lead? of the O-RAN Alliance looking for a statement that it has passed.  I have not gotten that statement from him yet.  I don't know how many votes needed to pass.  There are 15 passed votes.  I am waiting for confirmation from Zbynek.
      14. Jinri: I can confirm.
      15. Jack: We will consider that an approved vote for people who want to implement Flex-ran implementation around integration and test as an initial working DU at the end of maintenance assuming that we don't have further delays.
6. Copyright updates
   1. Jack: As i described last week there was a vote with the board on an initial copyright request.  Jinri did it get reviewed or is it still in process?
   2. Jinri: It is not officially approved yet.
   3. Jack: An updated one was brought forward that addresses all of the open source software needs.  They are updating and going through the process email vote. The process has started Stephan has introduced it for the vote.  The board votes by mail and it takes a few weeks to vote through that process.  Any questions:

7. Marketing of the current release (WG, LF, PR)

   1. Virtual Exhibition.

      1. Jack: The bronze release will be coming out mid next month.  We've heard from companies that want to add a statement as a part of the release.  We're working on writing comments in the release on capabilities please send Jack and Jinri a note.  We are starting to pull together the body of the content for the release.   Once we get something together we'll be adding the comments.
      2. Jinri: Just a reminder tomorrow will be the deadline for the A1 review of O-RAN Alliance for June but so far I have not gotten feedback from anyone.
      3. John-Paul: Ericsson will submit later today to Paul Smith within the deadline.
   2. OSC Logo status.

8. Status of Open Action Items (Old Business)

   1. Action/ William DIEGO update on the coordination with the O-RAN test group
      1. William: I sent an email two days ago in order to complete info on our test integration end to end test specifications.  We are working on that.  We expect to have the final version in two or three weeks.  
      2. Eng Wei Koo: We have to get together with Lusheng to get thru the contribution to ask for help.  I sent it out a draft.  I can send to this team.  We came together for this discussion and will get it together for next week.
   2. Action/ William DIEGO and user-59b16 lead the effort to organize a long term discussion with Viavi about the coordinated view of the test group and their activities.
   3. Action/ Jinri Huang status of the O-CU 5G contributions to repos.
      1. Jinri: For the O-CU part will be from ICT.  They are in the process of signing a CLA and are getting their F1 code ready.  They will create a repo and update the code once CLA is signed.
      2. Rittwik: Will there be testing for Bronze release?
      3. Jinri: No.  
      4. Rittwik: Will there be ODU High?  OCU should look at a spreadsheet.  Action/ Rittwik: Share the spreadsheet with Jinri and Yingying.
      5. Jinri: As far as I know ICT attended last weeks meeting.
      6. Rittwik: Yes, they were listening in.  He should see the spreadsheet.
      7. Jinri: If you have his email you can send the spreadsheet directly to him and cc me.
      8. Jack: Are they a member of O-RAN or are they just going to contribute to OSC?
      9. Yinying; they are a member or O-RAN Alliance and WG8.
      10. Jack: At some point it would be good to set up a meeting with RSAC committee about laying out the timeline and feature roadmap.  I know it is a larger component with different section so people have a better understanding of how it will progress.  It is very important for the overall project.  Thank everyone for their efforts for bringing that forward.
   4. Action/ TOC continue last weeks review of projects.

9. Standing Agenda Items (Brief Status of Ongoing Activities)

   1. Release Manager Trishan de Lanerolle /Release Planning: Weekly TOC Scheduling

      1. Bronze Timeline

         1. Jack: We're into ETE testing and documentation.  We should be planning an O-RAN demo of the capabilities of the Bronze release.  Things are sliding a bit.  We should be looking at inviting the WGs and members of O-RAN to see the release features.
         2. Lusheng: I have two items.
            1. One is report status of testing.  We're making good progress.  Most complex flow health-check made good progress.  Waiting for the Hello World xApp.  O-TU is able to talk to non real time RIC.  We're waiting for the Hello World xApp to be ready for testing.
            2. Matti: The gap was we didn't have the image being generated and the developer of the xApp was going to talk to someone to set it up.  It should be there or else let me know.
            3. Lusheng: I couldn't find any documentation for this xApp.  Do you have policy that will work with Hello World?  We can add/delete policy into A1 only applicable if we have the policy.
            4. John Keeney: We saw the body of the policy but not the schemas.
            5. Jack: We have some work to do here.
      2. Lusheng: There are 2 health-check flows that requires OAM artifacts.  We were able to deploy Frankfurt but had some difficulty with the other.
      3. Lusheng: for the traffic steering use cases we have the docker images on the nexus repos we should be able to start testing very soon.
      4. Lusheng: The O-DU lab testing we're getting a lot of help from Intel.  The cards that Intel contributed are having issues and we are debugging.
      5. Lusheng: We made a plan for the CI Flow and O-DU.  there are some CI flows are not being used because the Intel compiler will not allow.  Also testing requires particular LF software that is not good for that.  We will use CI flow using LF.  We will do the other tests in the lab.  we are planning to finish this by the maintenance release.  In addition to us other LF are using this process.
      6. Jack: Did you mention there was test framework code that would be available to the test group?
      7. Lushgen: Yes, there is OTF open testing framework ATT contribution repo IP/OTF because open source available for TGIG and OTIG.  If they have special requirements to build demos or goals we will work with them.
      8. Review Bronze Release Highlights

   2. user-59b16 Requirements Software Architecture Committee

      1. I received input from infra, testing teams for Cherry release.  Also had a good discussion with John Keeney.  There have been discussions with O-RU O-DU and some activities going on there.
      2. Jinri: Regarding software rental from Viavi.  I sent the request to TSC co chair.  It was not brought to EC but I will keep pushing.  How is the progress?
      3. Rittwik: Technical work is continuing. Viavi wants to get the work done.

   3. user-d3360  Integration and Test

   4. Report out from PTL: Stand-Up & Report Out on Blockers - next week we will start to cover this list.  Are there any major items that anyone would like to raise to the TOC this week? 

      1. John Keeney Non-RealTime RIC (RAN Intelligent Controller) (NONRTRIC)

         1. Bug fixing and testing before Bronze release.  WE are seeing scale and roundtrip times through the nonrealtime ric and controller.  As we scale up to 10x and 100x.  https support and ipv6 support has been keeping us busy with integration and test.  Cherry we've been chatting with Cherry release.  We will continue to discuss in RSAC in the coming release.  One way of improving there is no SMO project which is ONAP we are finding that we will we working with Cherry. 
         2. Jack: It doesn't mean that there wont be a project. At some point we will have to address but we dont' have enough working pieces to work on the higher level. 
         3. John: We have better alignment.

      2. Matti Hiltunen RIC Applications (RICAPP) 

      3. Thoralf Czichy RIC Platform (RIC)

         1. See status notes under "Status 2020-04-29 and 2020-04-30 and 2020-05-06 and 2020-05-12" in Bronze Release (Jun 2020)

      4. user-a934b O-RAN Centralized Unit (OCU) 

      5. Sachin Srivastava O-RAN Distributed Unit High (ODUHIGH)

      6. Zhimin Yuan O-RAN Distributed Unit Low (ODULOW)

         1. Jack: How are things going?
         2. Zhimin: We are quite busy to prepare release package.  We are doing the final security and quality review and then we can go upstream.  For Cherry release our committee requirement and integration with other project feature perspective.  The O-DU low was support the typical config.  We have doubt about going to the Massive MIMO or not?  We have a doubt here and would like to know what is the community requirement for O-DU low.  
         3. Jack: That should be worked through the RSAC committee.
         4. Rittwik: We have a pretty good idea of O-DU Low and High.

      7. Martin Skorupski Operations and Maintenance (OAM)

         1. I was looking to the Cherry release.  In bronze we depend on the models in order to have nice implementations ready.  We didn't get something from O-RAN in time we are pointing to models that are readily available.  We have to move on because this complicates the components.  All the software I had in mind for the O-RAN sC is in Open Daylight and ONAP.  It looks like my team has to move into the modeling teams of O-RAN Alliance so we can have some models available for SC.  Basically for Cherry release ONF is now coming up with a near RTRIC project they are asking for models.  I don't have many models to offer in the Cherry release.  I don't know what to contribute in terms of software.
         2. Jack: Modeling is a critical issue.  Let's put this on the table for further discussion.  Jinri let's highlight on the O-RAN Alliance side that this is a blocker for this space.  We have to come up with a strategy.  Let's chat on the side and see what we can come back with from that community.  Rittwik this effects your items as well.  Let's make it clear what our blockers are in this space.
         3. Martin: I am aware so I started working with 
         4. Tracy: I have some slides that describe the status open issues.  When you discuss this with the O-RAN Alliance folks these slides show progress and pitfalls.  One of our problems not a lack of models but too many models.  It is good to import models as long as they integrate neatly across a common framework makes it complicated.
         5. Jack: Is that something you can share on the wiki?
         6. Tracy: Yes. 
         7. Jack: 2022 is a long way out.
         8. Tracy: We're following Agile there is a spec and models.  example O-1 TR adaptor is based.  The models where the open front haul.  We are not where we need to be with A1, A2 and O1 is still a work in progress.
         9. Rittwik: What about the impact to simulation.
         10. Martin: I made tutorials.
         11. Jack: If the PTLs feel it is time for them to move on then let us know and we will find others to take over.  It's been a year and it is not unusual.

      8. Alex Stancu Simulations (SIM)

         1. We are still struggling with the E2 simulator.  We will work with the data from AT&T and will continue progress in the maintenance release for the traffic steering use case.  For Bronze release it will be for data pipeline will move to bronze maintenance and xApp testing will happen in Bronze.
         2. Jack: Samsung status?
         3. Rittwik:  I will follow up with Samsung.  Lusheng may know more.

      9. Xiaohua Zhang Infrastructure (INF)

         1. Enabled Ansible bootstrap so we have an all in one single server solution.  In Cherry we will extend single server solution to multiple.  There's another target to do interoperability to do O-DU High, Low to be used by the infrastructure.

      10. weichen ni Documentation (DOC)

          1. Everything looks good.  There is a lot of help from each project preparing the documentation and I am preparing the documentation branch for bronze release. 
          2. Jack: Is there an overview document?
          3. Weichen: I am creating for Bronze.

      11. (TBD) O-RAN Radio Unit (ORU)

10. New Agenda Items (New Business): New Items Submitted (+speaker) & Open Call to TOC For Additional Items. 

11. Planning for Next Meeting

    1. Jack: prioritize the test teams efforts.  Support Weichen with documentation.  Continue discussion with the RSAC committee with O-RAN to get  things done.
    2. In two week on June 3rd I'll be out.  Jinri if you will be available please lead the meeting and Lusheng will be my proxy.
