  3. Review and Agree to Minutes of Previous Meeting

    1. Decision: Move by John-Paul, second by Jinri. No objections. Minutes 20201014 approved. 

  4. Review of Today's Agenda  

  5. Release Votes and Approval.
  6. Copyright update. 
    1. Action Point Jack/Jinri: Check approval to use O-RAN ASN.1 by OSC with O-RAN legal to clarify what spec. version it relates to.
      1. Supposed to have meeting last Friday between OSC, LF and O-RAN Alliance but due to scheduling conflicts this meeting has been moved to this Friday.
      2. John K: It is important to prioritise this meeting and focus on questions between OSC and O-RAN Alliance.
      3. Jack: Understood. 
      4. Jinri: SDFG held recent discussion on copyright for 3GPP. Securing copyright permission alone does not appear to be sufficient to re-use ASN.1 and YANG models in OSC. This has been raised to TSC.
      5. Jack: There are 2 separate threads on copyright: 1) O-RAN Alliance ↔ OSC - process for OSC use of O-RAN specifications and; 2) External SDOs ↔ O-RAN - process for O-RAN (Alliance and Software Community) use of SDO material.
  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.)

    1. Jinri: O-RAN Virtual Face to Face meeting discussed security concerns in OSC. CII badging principles, similar to those used in other open source projects, were presented and discussed. 
    2. Jinri: MVP discussion took place last Friday. At this stage, it looks like there is no concrete conclusion on how the MVP processes should work. However, each O-RAN Alliance WG has an action point to investigate how MVP could work for Network Slicing and Traffic Steering use cases. Further discussion needed.
    3. Jinri: TSC meeting will take place tomorrow (Thursday).
    4. John K: Can you comment briefly on likely impacts to OSC from the MVP discussions?
    5. Jack: There are so many topics to cover. One of the main aims of the MVP process is trying to zero in on the use cases and features which can demonstrate the most value from O-RAN to operators and other stakeholders. One of the ways to make O-RAN relevant is to see operators adopting O-RAN concepts into their product plans. MVP is an attempt to look at operator needs and identify which parts of O-RAN we should prioritise for immediate elaboration. Operator survey is being parsed to understand requirements on MVP and how to communicate this to the broader community.
    6. John K: How would these requirements be addressed by OSC? 
    7. Jack: RSAC would look at the MVP priority list, analyse what the topic means in terms of requirements and then proceed from that point. There are challenges here for OSC. Some of these MVP topics will likely need some analysis in order to generate OSC requirements. 
  8. Status of Open Action Items (Old Business).

    1. O-CU development and O-CU for Cherry traffic steering use-cases. 
      1. Jinri: O-CU contribution team cannot commit to making contributions on an ongoing and consistent basis. Need to call for new contributors to this project.
      2. Jack: O-CU project needs to be re-planned and contributors need to be assigned. How to move forward with testing plans and simulation plans with O-CU. Impacts are felt outside of O-CU project. Action Point is needed to raise this to EC.  
    2. Cherry deliverable summary page (see  Cherry Release (Dec 2020)) . Update once a month and review on first TOC call of a month.
      1. Jack: The Cherry release deliverables have been reviewed over last TOC meetings. These deliverables have also been presented at the O-RAN Virtual F2F meeting.
      2. Jack: Something we need to consider from the O-RAN Virtual F2F meetings. Which aspects of the O-RAN Virtual F2F meetings do we need to include in our Dawn release plans e.g. POR, Security.... OSC Dawn is a critical release. Need to focus on what we are really going to accomplish in the Dawn release to show value from OSC. This will be a theme of the coming weeks' Dawn requirements discussions with PTLs. Dawn should demonstrate O-RAN capabilities by ensuring that contributions can be used by other projects / companies. Also, Dawn release should demonstrate value from the O-RAN mission. 
  9. Standing Agenda Items (Brief Status of Ongoing Activities)

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

      1. CherryTimeline 
      2. Jack: It's getting close to the end of Cherry release. We are currently finishing up development cycle sprint 4. PTLs need to consider updating wiki etc. Also, PTLs should start to raise which items will make the release and which items won't. How do we push important items over the line to be included in the release? 
      3. Rittwik: In Cherry, O-DU (High and Low) should deliver most of its commitments. For example, almost all parts of the Traffic steering use case are working. A video has been created for the MWCA virtual exhibition. SMO use cases are also looking good to be included in Cherry. O-DU (Low) and O-RU integration is looking like it may be a stretch goal. Being set up in the lab now. UE attach is the focus of the activity at the moment.
      4. Jack: O-RU and O-DU integration sounds like it is mostly test configuration. There is a test and integration window at the end of each release which can be used to finalise scenarios such as O-DU and O-RU integration. 
      5. Jinri: For O-DU (Low) and O-RU what is the expected output?
      6. Rittwik: Successful acceptance tests. FAPI interface should be working correctly - messages between the O-DU and O-RU being sent and received successfully. 
      7. Jack: Felix's integration and test responsibility is to ensure people can re-create the systems. The INT project is not responsible for testing the functionality of individual components. Something we should start to consider is the relationship between OSC and TIFG in the Alliance. For example, how does TIFG take this hand-off and do something with it? How do we encourage TIFG to become more engaged with a broader test plan, not just a software and integration test program? Need a discussion with TIFG to understand their plans moving forward. Action point Rittwik to set up meeting with TIFG to align deliverables and make more use of use cases.
    2. Rittwik Jana Requirements Software Architecture Committee

      1. Jack: Where do we stand on our plans for requirements in Dawn release?
      2. Rittwik: PTLs have provided inputs.
      3. Jack: What are the 3 major focus areas that Dawn release will advance?
      4. Rittwik: 1) Getting more sophistication into SMO. 2) Use ML to create more sophisticated traffic steering. 3) Near RT RIC platform to address dimensioning and scalability.
      5. Rittwik: In addition to the 3 areas mentioned we should also consider
        • O-DU low and high are at a point where they are interacting with each other - the capabilities are minimum viable. Should we enhance these capabilities? Request guidance from TOC.
        • Non-RT RIC focus on A1-EI. 
      6. Jack: Any security related items?
      7. Rittwik: Amy wants to sit down with each PTL and address CII badging requirements for each project. 
      8. Jack: I think we should view security as a 4th major theme / focus area for the Dawn release. Security assessment and compliance with security task group to bring existing software "up to code" with security rules. Badging has a lot to do with documentation and procedures. 
      9. John K: A lot of OSC components and functions are not production grade. However, some of the security task group requirements are looking for production grade support. This has the potential to reduce capacity to deliver 'functional' requirements from the OSC.
      10. Jack: Agree with some of what you say. The focus of the security engagement is to: 1) Document what they ask for and 2) Assess what is meaningful to OSC. More discussion is needed in the community on these two points. 
      11. Jack: Regarding SMO, the first objective of SMO should be to deploy and manage all other OSC components. Support an OSC deployment and LCM of the components. Can then be used by OTIC - this demonstrates value of OSC. RSAC might want to take this into account when discussing SMO requirements for Dawn.
      12. Matti: The E2-AP spec is coming in November. How do we prioritise that for Dawn?
      13. Jack: How much work is it to get to full compliance for existing use cases in time for the Dawn release? Needs some more investigation into the impact.
      14. Matti: Not likely to impact the xApps but E2-AP would likely impact integration between Near RT RIC platform and simulator.
      15. Jack: We are use case driven. How would this affect the use cases themselves? Do we need to change use cases or add new ones?
      16. Rittwik: 
      17. Tracy: Wanted people to give some thought to the results of the operator survey. Recently completed the O-RAN Plugfest. Another PoC OSC release 3. Consider the message that OSC wants to promote / convey. 
      18. Jack: Good points. Let's continue that conversation.
      19. Tracy: We are doing a cross-regional OTIC / MVP live demo, Thurs Dec 3rd. 
      20. Jack: Any interest in the OTIC to reproduce the test bed
      21. Tracy: Yes, we want to be in a position to have the official integration tested 
    3. Zhe Huang (Felix) Integration and Test

  3. Review and Agree to Minutes of Previous Meeting

    1. Decision: Move by John-Paul, second by David. No objections. 20201007 minutes approved.

  4. Review of Today's Agenda  

  5. Release Votes and Approval.
  6. Copyright update. 
    1. Action Point Jack/Jinri: Check approval to use O-RAN ASN.1 by OSC with O-RAN legal to clarify what spec. version it relates to.
      1. Last week there was a meeting between O-RAN Alliance and LF to review copyright options moving forward. Focus of the meeting is on how to get a good solution to the copyright issue taking examples and experiences from other LF communities. Follow-up meeting planned for this week.
  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.)

    1. Jack: Good meeting last Friday - almost 100 people on the call. RSAC led the discussion with PTL support on Cherry release content and plans for the Dawn release. O-RAN Minimum Viable Plan (MVP) was one of the main discussion points and should help inform OSC content and deliverables going forward. Some concerns raised around O-CU progress. Overall, the feeling is that OSC is making progress. Link to RSAC presentation included here
    2. Jinri: O-RAN virtual F2F meeting is ongoing and there are a number of OSC related discussions planned for the coming days.
    3. Jack to present statement from ONF.
    4. Jack: O-RAN Alliance is always in discussions with other organisations about potential collaboration to build relationships. ONF is one such organisation. ONF made an announcement about SD-RAN over the summer. O-RAN Alliance sought some clarifications about parts of the ONF statement. ONF published an update this week to affirm their intention to collaborate and align with O-RAN Alliance on various topics. The O-RAN community promotes collaboration and will work with ONF to advance the goals of the greater community. ONF collaboration will start to become visible in the OSC plans over the coming weeks / months. John Keeney asked if there were any OSC plans for working with ONF open source. Jack: A bit too early at this point. Things will become clearer over the coming weeks / months. 
  8. Status of Open Action Items (Old Business).

    1. O-CU development and O-CU for Cherry traffic steering use-cases. 
      1. Jinri has provided updates to Rittwik. Next step is to determine which parts could be delivered in Cherry and which parts will target Dawn. This will be discussed at the O-RAN Virtual F2F.
      2. A replacement PTL is needed for this project - it is not viable to proceed without a functioning O-CU project.
      3. Jack: Longer term working item that O-CU is one of the OSC's main challenges now. 
      4. Jinri: Need to wait 1 more week to determine whether current O-CU team can continue to contribute.
    2. Cherry deliverable summary page (see  Cherry Release (Dec 2020)) . Update once a month and review on first TOC call of a month.
  9. Standing Agenda Items (Brief Status of Ongoing Activities)

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

      1. CherryTimeline
    2. Rittwik Jana Requirements Software Architecture Committee

      1. John-Paul: There is a LF Networking Virtual Technical Meeting taking place this week and one of the topics being discussed tomorrow (Thursday) at 09:00 EST / 15:00 CET is ONAP - O-RAN collaboration. Link to the LFN event and schedule is here
      2. Rittwik: RSAC wants to accelerate development in OSC and has some concerns about some things which may work against this goal. OSC / O-RAN doesn't have control over other open source bodies. It is important that "O-RAN inherent" code resides in OSC and only downstreamed where appropriate. OSC purpose is two-fold: 1) To align with O-RAN specifications when published; 2) OSC also serves a pre-specification function - provide input to the Alliance. The two way flow between OSC and O-RAN Alliance is important for the success of O-RAN.
      3. Rittwik: Also, the current status of the OSC O-CU project is a concern. The Amber release is monolithic and not being used very much. O-CU is lagging behind from a contribution perspective. Progress meetings would be helpful. RSAC recommendation is to work with OAI to source a more feature rich O-CU for OSC use. Need a longer term plan for O-CU. 
      4. Dave Kinsey: Referring to the cross-project topic. I am concerned about pushing functions which are O-RAN inherent into other open source projects and maintaining them there. If functionality is O-RAN specified it should be implemented in OSC, not in other open source projects e.g. ONAP. Take A1 Policy Management in Non-RT RIC as an example. The A1 controller should be seen as platform functionality and therefore can reside in ONAP. However, the A1 Policy Management service is a function which is specific to O-RAN and should therefore be located in OSC. We need cleaner boundary / lines between OSC and other open source initiatives.
      5. John Keeney: Implementing the A1 controller and policy management features in ONAP was a response to RSAC requirements at the time.
      6. Dave K: OSC A1 adapter is ok in ONAP (physical termination ok in SMO). A1 Policy Management is not in the same category. SMO doesn't need A1 Policy Management. Need a strategy on how to de-couple these things.
      7. John K: One of the main reasons the A1 controller and policy manager was to ONAP was in response to other companies developing similar functionality in ONAP, thereby splitting / fragmenting the development. Moving A1 functions to ONAP was an effort to prevent fragmentation.
      8. Dave: Understood. Need a process / procedure to agree on how to draw lines between OSC and other groups.
      9. Tracy: When you said we used the ONAP based A1 controller for expediency, is there a different A1 controller implementation which we could / should use?
      10. Dave: No, the ONAP A1 controller is the chosen one.
      11. Tracy: A1 Controller was not implemented in ONAP for expediency. This was implemented in ONAP because it was the right place to locate the A1 controller function.
      12. Dave / Rittwik: Agree.
      13. Rittwik: The concern is where source code which is inherent to O-RAN is implemented and needs to be maintained in ONAP.
      14. Jack: There is a delicate balance between not replicating code unnecessarily and creating complicated relationships / dependencies between open source projects delivering on different cycles. 
      15. Rittwik: There are other 5G stack initiatives such as OAI and ONF and we need to have a clearer view on how to collaborate between OSC and these groups too.
      16. Jack: Agree that collaboration is important. Need more discussion on this. Licensing is an issue as there are different licensing models in place across, for example, OAI and OSC. ONF is still in the early phases of discussions within O-RAN. More work required on how collaboration might look. O-RAN EC was clear that all upstream projects are good places not to duplicate work, however there is no single commitment to take ONAP implementation for OSC SMO. EC wants a partnership with other open source projects but does not want to yield the work to non-O-RAN groups. Looking to something which works for entire O-RAN community, not just OSC.
      17. Action Point Rittwik set up a meeting to review and discuss collaboration models and principles between OSC and other open source initiatives e.g. OAI, ONAP etc.  
    3. Zhe Huang (Felix) Integration and Test

      1. Action Point Felix Update the INT project wiki with PTL name and include update on plans for Cherry / Dawn.
    4. Report out from PTL: Stand-Up & Report Out on Blockers

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

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

        1. Finished the O-DU LOW FAPI development and verified with 3rd party stack. Integration with O-DU High ongoing and progress is being made.
        2. Jack: How is integration with Viavi O-RU Emulator progressing?
        3. Zhimin: We will start integration in Cherry timeframe but will likely need to complete the task in the Dawn release. Need to discuss CI for O-DU Low with Integration team.   
      7. Martin Skorupski Operations and Maintenance (OAM)

      8. Alex Stancu Simulations (SIM)

        1. Implemented more message types in collaboration with Samsung. HCL is working on assessing benchmarking. OTF integration of E2 likely to move to OSC Dawn release. Working on upgrading Netconf server framework for O1. Looking good to be delivered in OSC Cherry. Aligning with latest models from O-RAN Alliance is an ongoing activity.
        2. Jack: We are doing a lot of work on the emulators and stubs for the emulators. Is any of the code being contributed to OSC?
        3. Alex: Some work in progress. Plan to create new repo in SIM project to host Viavi data - licensing discussions ongoing with Viavi - on target to be available in Cherry.
        4. Jack: Do you need resources to advance E2 issue?
        5. Alex: Samsung and HCL are working now so shouldn't be any issues.
        6. Jack: Just raise your hand if you need resource help.
      9. Xiaohua Zhang Infrastructure (INF)

        1. Presented at O-RAN F2F. Finished AIA with HA. Working on AIA with additional node. Integration ongoing.
        2. Jack: Are there any discussions to support non-Intel framework?
        3. Xiaohua Zhang: Yes, that will happen in the Dawn release. 
        4. Jack: O-DU Low is not suited for this configuration. Do we need another O-DU Low implementation or another software project to progress? Need to discuss at RSAC.
      10. weichen ni Documentation (DOC)

        1. Jack: It would be good to get an update on this project.
        2. Jinri: Will raise with Weichen.

  4. Review of Today's Agenda 

    • Jack: O-RAN Virtual F2F starting on Thursday 8th October.

    • Juha: Is there any update on the OAI Meeting which can be shared? Jack: Meeting took place, good discussion, no action items yet. Issue has always been how to synchronise two different software projects. OAI uses FRAND licence which is a challenge for OSC.  The meeting addressed three discussion points: 1) Alignment between OAI and OSC objectives. 2) How do we incorporate and use copyrights. 3) How can OSC and OAI collaborate on software and testing. Current thinking is to use a similar approach as Intel in the O-DU project. Needs to be resourced by people interested in bringing OAI closer to OSC. Discussions ongoing.  
  5. Release Votes and Approval.
  6. Copyright update. 
    1. AP Jack/Jinri: Check approval to use O-RAN ASN.1 by OSC with O-RAN legal to clarify what spec. version it relates to.
      1. Jack has a meeting this week with O-RAN legal team and LF legal team. Hoping to make progress on copyright issues at this meeting.
  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.)

    1. AP PTLs: One-pager about strategy/challenges and what could be leveraged from O-RAN Alliance for Dawn. Please send to RSAC, preparation for O-RAN F2F. 
    2. O-RAN Virtual F2F Agenda is published on the O-RAN Alliance Wiki. From an OSC perspective, at least the following sessions will be of interest:
      1. Friday 9th October, OSC will kick off Dawn release discussion. RSAC will lead the discussion. Rittwik has received input from some PTLs. Rittwik and David have drafted some of the Dawn epics but would like more visibility on the spillover items from Cherry into Dawn and their prioritisation relative to Dawn activities. Rittwik to follow-up with Viavi about a possible new xApp / rApp use case.
      2. Wednesday 14th October, Cross-OSC discussion on security requirements. Working to improve security principles and review current tooling. Emphasis on interface transport security.
      3. Friday 16th October, Discussion on functional architecture or SMO. Important to establish SMO project to enable and demonstrate functionality from all OSC projects. 
  8. Status of Open Action Items (Old Business).

    1. O-CU development and O-CU for Cherry traffic steering use-cases. 
      1. Jinri has provided updates to Rittwik. Next step is to determine which parts could be delivered in Cherry and which parts will target Dawn. This will be discussed at the O-RAN Virtual F2F.
      2. A replacement PTL is needed for this project - it is not viable to proceed without a functioning O-CU project.
    2. Cherry deliverable summary page (see  Cherry Release (Dec 2020)) . Update once a month and review on first TOC call of a month.
  9. Standing Agenda Items (Brief Status of Ongoing Activities)

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

      1. CherryTimeline
    2. Rittwik Jana Requirements Software Architecture Committee

    3. Zhe Huang (Felix) Integration and Test

      1. Integration meeting scheduled after this TOC meeting. Agenda includes Dawn planning and licence scan plans.
    4. Report out from PTL: Stand-Up & Report Out on Blockers

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

        1. Working on prototyping AI-Enrichment Information coordination services. Implementing Hello World registration / catalog function. Supporting evolution of A1-Policy specification from WG2. Documentation and integration testing ongoing. No blockers.
        2. Jack: Capture the ONAP Guilin activities and explain the dependencies in the Non-RT RIC One Pager for OSC Cherry. 
      2. Matti Hiltunen RIC Applications (RICAPP) 

        1. Helping on E2 Simulator and xApp framework. Needed for KPIMON from Samsung. Still working on delivering this for the maintenance release. Would like to get ready in time for MWC North America.
        2. Development proceeding on xApps - SSD, Load Prediction and Anomaly Detection. These xApps beef up support for the Traffic Steering use case.
        3. Jack: What should we really be trying to accomplish for xApps in Dawn? Matti: KPIMON working with E2 Simulator and Viavi RAN simulator is a big step forward. Push the use case beyond the Near RT Platform and start to integrate with other O-RAN components.
      3. Thoralf Czichy RIC Platform (RIC)

        1. Contributions from HCL and Samsung are ongoing. Working on Sonarqube for repos. They are also helping on the Simulator. Upgrade to latest Helm version, Nokia will work on K8s upgrade. Some items moved from Cherry. Matti and Thoralf gave Near RT RIC presentation at ONES. Clarifying and resolving copyright/licensing issues between O-RAN and OSC is very important for making progress in Near RT RIC project.
        2. Jack: What is the major advancement for Near RT RIC in Cherry? Thoralf: Finalising the E2-AP support in Cherry. Support for getting statistics on A1 and E2 messages. 
      4. Yingying Wang O-RAN Centralized Unit (OCU) 

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

        1. Working on UE attach. Testing needed. Integrating with O-DU (Low). O1 interface support getAlarmList for the HealthCheck use case. Facing some issues pushing code to gerrit. Hoping to resolve issues soon.
        2. Jack: O-DU is important component - it demonstrates a lot of the interfaces across O-RAN NFs. How do we get a measure of overall progress on O-DU (High)? How is project tracking performed on each of the main functional areas so we can see overall progress? Ganesh: There are dependencies from O-DU (High) to other O-RAN NFs and specifications. Need a baseline across all NFs based use cases. RSAC should be the place to drive this common functionality / use case driven approach. Jack: We have spent first 3 releases putting building blocks in place. Now, we need to look to the next 3 OSC releases to understand how we can demonstrate the value from an open source and integrated O-RAN environment. Rittwik: We have consensus agreement between some O-RAN projects for an O-RAN MVP but we need to push forward more with this. Next immediate goal is to focus on getting attachment of a UE.
      6. Zhimin Yuan O-RAN Distributed Unit Low (ODULOW)

      7. Martin Skorupski Operations and Maintenance (OAM)

        1. Adopted all existing specifications. In discussions with SMO on App LCM use cases. Handover from OAM to SMO is in early discussion, no handover as yet. O-RAN Alliance WG1 has draft versions of O1 YANG interfaces based on 3GPP. These are almost ready to be tested towards the SIM project. 
        2. Jack: What do you see as the next big step for Dawn? Martin: Complete deployment of vNFs, CNFs and PNFs too. Jack: How is the OAM interface towards Near RT RIC? Martin: Needs some more discussion to align the OAM protocols. Jack: Should be a focus to bring the Non-RT RIC, Near RT RIC and SMO closer together from an OAM perspective. Please bring this to the relevant O-RAN Virtual F2F discussions.

  6. Copyright update. 
    • Jack: Discussed with EC, 2 aspects
      • 3GPP - more complex as they are outside entity
      • For O-RAN documents - in process to schedule meeting with O-RAN Legal and LF Legal. Voted to approve ASN.1 and tables and messages from O-RAN spec by board. Board also allows EC to deal with individual requests.
    • Jinri: Volunteers from Qualcomm and TIM are now working with SDFG on 3GPP related topic. Gu Su also helping with it and in contact with Stefan.
    • Thoralf: We need ANS.1. Are you confident we will end up with workabdle solution with ASN.1 code in LF CI?
      Jack: I believe ANS.1 approval was given by board.
      Jinri: Yes, but there is 60 day IPR review going on in O-RAN.
      Thoralf: Is it OK to use ASN.1 from older specification?
      Jack: I believe that is what the approval is for.
      Thoralf: Can we push it so we have the approval in format that we can procede with ASN.1 use in OSC?
      Jack: I will arrange it with Stefan. AP Jack/Jinri: Check approval to use O-RAN ASN.1 by OSC to clarify what spec version it relates to.
      JInri: Lets be careful, this review process will involve also the older specification.
  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.)

    1. AP Rittwik: Setup separate meeting about OSC RSAC and relationships between components ... invite the TOC members. DONE
      1. Rittwik: I am creating one short slide deck for TOC to review it. Will send it to TOC.
    2. Schedule for F2F meeting:
      1. Jinri: Agenda is avalable on O-RAN wiki for members. We have session from kick-off discussion for Dawn release on October 9th 8-10AM EST but we need to align it with RSAC.
      2. Rittwik: We can do it but maybe no for full 2 hours.
        David Kinsey: We would like one-pager strategy/challenges/status and what they could leverage from PTLs. AP PTLs: One slide about strategy/challenges and what they could leverage from O-RAN Alliance for Dawn.
        Jinri: I propose to have two parts for the session as last time. First review of Cherry and then plan for Dawn.
      3. Jinri: There was first O-RAN review of proposed demos for MWC. There are 24 demos from OSC.
      4. Jack: Paul Smith is working on survey to select and organize priority items in TIFG. We should take the results into account when planning our activities.
        Jinri: This is related to minimal viable product. On the F2F there will be at least 1 dedicated session on this topic.
  8. Status of Open Action Items (Old Business).
    1. O-CU development and O-CU for Cherry traffic steering use-cases
      1. Jinri: We did not get positive result from the negotiation it the supplier company yet. It is still ongoing. Gu Su is organizing meeting with PTLs to get requirements from other project for O-CU to know what needs to be implemented. 
      2. Jack: We need to raise this to EC as risk.
      3. Jinri: I plan to have it as item on EC meeting this Friday.
    2. Cherry deliverable summary page (see  Cherry Release (Dec 2020)) . Update once a month and review on first TOC call of a month.
  9. Standing Agenda Items (Brief Status of Ongoing Activities)

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

      1. CherryTimeline
    2. Rittwik Jana Requirements Software Architecture Committee

      1. Rittwik: Radisys may be able to provide close-source CU for testing of Traffic steering use-case.
        DU low and DU hi in lab are starting to interact. Viavi is working on delivery of RU emulator and EPC, shipped today.
        Jack: Does it include Matti's XApp activity or is it separate activity?
        Rittwik: This is about DU high and low interaction and getting DU attached. The other traffic steering work has 2 stages. First stage is for MWC LA to upstream measurements into XApp, second stage will allow control action to the O-CU for MWC Barcelona. It exercises the XApps but it is separate from the O-CU and O-DU pairwise testing now. 
      2. Jack: S out of the E2E Use-cases for Cherry what is covered?
      3. Rittwik: DU is incorporating health-check and traffic steering. And also call flow num. 2. and 3 work is starting in SMO.
    3. Zhe Huang (Felix) Integration and Test

      1. AP Felix: Make ticket with LF, Trishan with help speed up the solution for image retention in CI/CD pipeline. DONE

      2. Felix: Reviewing automation jobs for Licence scanning. Plan to have meeting with LF Release team to understand available options.
      3. Felix: There was proposal for policy to allow some 3rd party licences on July 15th but was not voted on. I would like to ask about current status.
      4. Jack: I don't think we have enough info to have a vote. We need to figure out update and share it with everyone to explain as there was number of question. It could have impact on IPR policy so we need to write it u and check with O-RAN legal team.
      5. Felix: Maybe I can follow it and have call with all the PTLs. It has direct impact on the selection of license scanning tools. And also we would like to address outstanding issues in some of the repos.
    4. Report out from PTL: Stand-Up & Report Out on Blockers

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

      2. Matti Hiltunen RIC Applications (RICAPP) 

        1. Matti: New proposed XApp will not be part of cherry officially but work will start in it. Anomaly Detection progresses well, On KPIMON good progress was done on integration with RIC platform. There are small differences between E2 Simulator output and what KPIMON expects, it will be addressed by Samsung.
          We are getting data from Viavi simulator. We should be getting throughput and UE Id this week to start training.
        2. Rittwik: This simulator need to move to SIM project. It now sits in Azure. Viavi is looking into possibility of open-sourcing it.
        3. Matti: Can we put the simulator data in LF infrastructure?
        4. Jack: It is question of licence. We should check with Trishan
        5. Jinri: Open data sets can be published under CDLA. It is stated in our charter. The data-set can be placed on gerrit but for more options you should check with LF.
        6. Jack: It is slightly different as it is artificial data from simulator and not data from real network so we need to evaluate it carefully.

  3. Review and Agree to Minutes of Previous Meeting 

    1. Decision: Moved by David, seconded by John-Paul, no objection, 20200916 minutes approved.
  4. Review of Today's Agenda

  5. Release Votes and Approval.

    1. Decision: Mahesh made motion to approve new SMO repositories (details in mailing list), Ganesh seconded, motion passed.

  6. Copyright update. 
    1. AP: William to contact Orange OAI representative and schedule a meeting between OSC and OAI. (DONE)
      1. Jack: There is plan to have a call next week with broader topic.
      2. John-Paul: Is it reboot of conversation that happened earlier.
      3. Jack: It covers 3 topics:
        1. General relationship between OAI and ORAN
        2. Copyright material question
        3. How we could work together ... we can't easily use their code because of the license but it could be used in similar way as code from Intel but it would require joint project to align.
    2. Jack: copyright was discussed on EC and by email
      1. Getting alignment with 3GPP and ETCI for copyright permittion
      2. Copyright issues in O-RAN. Jack is working on clarification from O-RAN legal
      3. OSC is getting questions from external projects. OAI, ONF and ONAP are asking about specifications and access to them.
    3. Jack: Copyright permitting for OSC from specifications is in place. Anyone that uses OSC code downstream inherits this permision. One option solve it (7.2.3) is to document any information required from spec as part of OSC documentation so it can be used by external projects and work with OSC. For e,g. ASN.1 messages, error messages, API docs. We are trying to figure out good process for this.
    4. Thoralf: Is there now agreement between O-RAN Alliance and OSC on the possibility that OSC contributed has some king of licence for the specification?
    5. Jack: For any copyright material the the spec. OSC uses and is released as part of our docs and code under Apache 2 and Doc. licence is granted downstream copyright privilages for that information. I confirmed that with Stefan from the legal team.
    6. Thoralf: Do we have it written down anywhere?
    7. Jack: I am process of getting that clarified and confirmed. It should simplify the process for other organizations line ONAP and others.
    8. Mahesh: There is also question of changes and modifications. What to do If we find issue in copyright material and want to propose changes/fixes. E.g. from 3GPP? 
    9. Jack: With 3GPP it is more complicated. O-RAN is not member itself, it has to be thrue O-RAN member companies that are part of 3GPP and would sponsor the proposal. Then we would coordinate with other O-RAN members that would support it in 3GPP.
    10. Jack: ORAN has standards committee you can reach out to. Specifically Brian Daly as co-chair.
    11. John: Is it correct that OSC can use any spec. produced by ORAN and use, refer to, reproduce or redistribute code produces by O-RAN Alliance?
    12. Jack: For purposes of open-source software we do not have permission to reproduce whole spec., we can reproduce portions of spec that is  related to implementation of open-source SW. Tables, APIs, messages that are documented, etc.
    13. John: That would be bypassing the bypassing the ORAN licence in my opinion. Why would anyone contribute IPR material to ORAN if the spec can leak out via OSC under Apache Licence?
    14. Jack: It only allows for ANS.1, API, error messages, etc. only needed for he SW. The specific textual representation is covered by copyright. Copyright does not grant any patent protection or rights. It allows you to reproduce the representation of the material. It has no implication on patents.
    15. John: The Apache licence comes with patent grant. Does OSC have patent grant from ORAN?
    16. Jack: This still falls under O-RAN Alliance common patent agreement. You still have to get the permission from O-RAN to use that material, that the whole point of the contributions trough O-RAN and O-RAN IPR protection. Apache patent clause only covers the contributor where contributor states that he/she is OK with others to use the code. It does not imply anything from anyone else. As am not legal expert we should get the legal experts together on this. 
    17. John: Does not that move the burden to OSC contributors?
    18. Jack: As am not legal expert we should get someone from legal team to talk about this. From my understating writing the code or talking out the patent does not violate it. We should get experts on that together.
  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.)

    1. AP Rittwik: Setup separate meeting about OSC RSAC and other OSS relationships ... invite the TOC members.
  8. Status of Open Action Items (Old Business).

    1. AP: Ganesh ONF SD-RAN investigation summary (DONE)
      1. Ganesh: Check with lead developer of SD-RAN RIC. He wanted to clarify that they don't want to compete with OSC and they want to build RIC platform using their microONOS controller. The synergy and OSC and ONF is that there are external interfaces like A1. They plan to explore collaboration with other RIC contributors. There is not yet formal call for it. 
      2. John-Paul: If ONF is interested in creating separate community can it make another challenge and fragmenting our efforts? The concern is speeding the effort too thin.
      3. Jack: I agree with your concern. It is big task and if they do not bring their development here it is concerning. If one company makes XApp for one RIC and it will not work with the other, that would be a problem. Interoperability  is really key. I have heard comments from different companies. ATT is involved with addressing this  issue. ONF has body of SW they want to leverage to move forward. This is really issue of not just ONF, OAI, TIP, ONAP, Acumos. All these entities need to be  
      4. Tracy: I agree. THere is Rivalry between these organization in one for or the other but I don't see any obstacle for OSC to import anything from ONF.
      5. Jack: The challenge always is that without the people having the in-depth expertise it is hard to reuse the code from external projects.
      6. We hope we can make sure we can interoperate and make more useful system.
    2. O-CU development and O-CU for Cherry traffic steering use-cases
      1. Jack: We are in trouble with this project. Current O-CU project is being reorganized. We have initial contribution from company sponsored by CMCC. This is very important topic for OSC and I think we need to raise it also to EC.
      2. Rittwik: There are couple of alternatives. We need O-CU to work for traffic steering. Asked Ganesh if they could make close-source contribution. That is the first option.
        1. Ganesh: Had to do due diligence to make sure it will be compatible. We should give you update next week.
        2. Rittwik: Second one is option from Viavi that is NSA. It may be usefull but not immediately for traffic steering that needs SA. Third is OAI CU but it does not have E2.
        3. Rittwik: You can buy CU simulators but they do not have E2 also. From open-source CMCC aproach was right way but it it got stalled. It is good idea to bring to EC.
        4. Rittwik: Traffic steering use-case will flow into Dawn so we will need O-CU going forward.
    3. Cherry deliverable summary page (see  Cherry Release (Dec 2020)) . Update once a month and review on first TOC call of a month.

      1. Initiated discussion with Mahesh to set up the CI/CD pipeline. Also working with O-DU team to address problem with CI jobs.
      2. Our current docker repos in CI pipeline will constantly remove images after a while ... this creates problem for the CI pipelines. Should discuss this with LF to find better solution.
        1. AP Felix: Make ticket with LF, Trishan with help speed up the solution.

    1. Security aspects brought by security team.
      1. Jack: OSC would like to have new screening tool. It is 3rd party pay to use tool. LF has comparable tool the would be free but it is not same so I need to go back to security group. There is overall focus in O-RAN to address the security. The team is looking into our procedures and how to improve them from security perspective. More security items are to come. We need to make sure we are up to speed on security guideline as we produce more useful modules. 
    2. There is also badging in LF. I am looking for volunteer there if someone has interest or experience with it.

  3. Review and Agree to Minutes of Previous Meeting 

    1. Decision: Moved by David, seconded by Jinri, no objection, 20200909 minutes approved.
  4. Review of Today's Agenda

  5. Release Votes and Approval.

  6. Copyright update. 
    1. AP Jinri: Will check with EC about the O-RAN contrib. withdrawls concerning copyright.  DONE
      Jinri checked with EC, they promised to expedite. 
    2. Jinri review copyright questions sent by John Keeney but the answer needs copyright expertise so Jinri asked in mailing list for volunteer from OSC that would help with this and also generally with copyright as longstanding issue for OSC. Gu Su would like to help with this topic and act as interface between OSC and other parties concerning copyright.
      1. John Keeney: For clarification, questions I asked are related to OSC and O-RAN. ETSI and 3GPP discussions are separate.
      2. Jinri: I believe Gu Su will reach out to you offline.
  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.)

    1. ONF SD-RAN relation to OSC:
      1. Jinri: Based on info from EC, ONF is preparing blog post to clarify some misunderstanding created by the original articles.
      2. Jinri: EC requested for OSC to create blog post about possible of collaboration with different OSS communities. I will reach out to Jack, Rittwik and others about the text.
        1. Rittwik: Do you mean down-streaming other communities for use in OSC or up-streaming?
        2. Jinri: It should be general statement stating our willingness to cooperate with other communities to avoid fragmentation of the ecosystem.
        3. RIttwik: One Item here is the collaboration with OAI. Is there progress? I saw article stating they are providing full 5G SW stack. 
        4. Jack: There is licencing complication. We can't use the lower layer code from OAI with the current licence as upstream project. Discussion about it was delayed over the summer but I am willing to discuss plan forward. Some of the higher level code is Apache 2.0 and could be used as upstream.
        5. Rittwik: One of our challenges is the O-CU. Even their O-CU could be helpful but they do not have E2 interface. We could extend the O-CU by E2 and contribute it to OSC but that needs resolved licencing first.
        6. William: I propose to schedule a meeting between OSC and OAI to reopen the discussion. AP: William will contact Orange OAI representative and schedule a meeting between OSC and OAI.
    2. Trishan: O-RAN received positive press on FCC 5G Open RAN forum. I think it was represented in one of the panels.
      1. Jinri: I don't think it was O-RAN Alliance represented there but individual companies.
      2. Trishan: Does O-RAN plan an promotion on that front?
      3. Jack: O-RAN Alliance is very supportive of the Open RAN aspect but it is non-political entity and does not delve into political forums. This is up to individual companies if they want to do so. As the organization O-RAN tries to stay out of politics.
      4. Tracy: There were principal investigator from Uni. of Utah and Rutgers Uni. as participants from OTIC US East and West describing the demos and use-cases but to specifically referencing O-RAN. I don't think anybody spoke in the voice of the O-RAN Alliance.
      5. Jack: Basically the Universities were presenting the work they are doing.
    3. Jinri: The was email call for demo on O-RAN Alliance plugfest virtual exhibition for canceled MWC America and MWC 2021. Interested O-RAN members should contanct Paul Smith. 
  8. PTL to provide information regarding O-RAN-related open source communities.
  9. Status of Open Action Items (Old Business).

    1. O-CU PTL to organize a meeting and invite all the relevant projects (O-DU-HIGH, OAM, RIC etc.) and discuss the cooperation/requirements b/w O-CU and the other projects
    2. O-CU PTL to prioritize the items shown on the presentation slide (https://wiki.o-ran-sc.org/download/attachments/10715432/OSC%20O-CU%20RelC%20-ICT-8.12.pptx?api=v2) to make sure some key features such as handoff could be supported for traffic steering use case.
    3. The team to arrange an offline meeting to further discuss the challenges.
      1. Rittwik: We are tracking 3 items in RSAC.
        1. Setting up the O-DU subsystem - going well, supported from Intel and Radisys, requires connection to Viavi emulator and O-CU
        2. We are not sure what is current status of OSC O-CU. As a interim replacement I proposed to use stripped down Radisys commercial SW as test fixture. We need it to attache UE and test O-DU-low and O-DU-high and hand-off between cells. There are 2 usecases: DU testing and traffic steering testing, both need O-CU.
        3. SMO item that Mahesh presented earlier.
      2. Jack: Yingying will not be cover O-CU PTL anymore. Is that correct?
      3. Jinri: Yes, we need to have a call for new PTL. I talked with ICT, they are doing internal evaluation but are not optimistic. Progress on current CU will be difficult.
        1. AP Jinri: Will talk with ICT DONE
      4. Jack: So need to replan O-CU development as current implementation is partially done. It is difficult to continue on such low-level code if original developers move on. We need to raise it as open issue. We have to use alternative solution.
      5.  Rittwik:  Viavi has internal R&D O-CU that could be potentially used.
      6. Ultan (Viavi): We are bringing it from internal lab, it is NSA currently.
      7. Rittwik: Could this be used in Cherry timeline
      8. Ultan: We will check, depend on our availability.
      9. Sphoori (Radisys): O-DU-high currently supports SA only.
    4. Cherry deliverable summary page (see  Cherry Release (Dec 2020)) . Update once a month and review on first TOC call of a month.

      2. Jack: Is the lab stable and accessible to work in?
      3. Rittwik: There are small access issues but we progressed to point where it is used for work.
      4. Rittwik: We are also looking into items that will flow from Cherry to Dawn and also working on preliminary draft for Dawn.

    *Quorum: 50% or more of total TOC voting members unless excluded due to attendance.   We have a quorum and can vote on activities.

  3. Review and Agree to Minutes of Previous Meeting 

    1. There is no comment raised on the 0819 meeting minute.

      1. Decision: Moved by David Streibl and seconded by Juha Oravainen, without objection and abstention, the 20200819 meeting minute is approved.
  4. Review of Today's Agenda

    1. No new items added;
  5. Release Votes and Approval.

    1. None.
  6. Copyright update. 
    1. JInri explained the background again (see previous meeting minute). Recent progress: There is araft proposal in which EC is requesting Board to authorize EC to grant the usage of the copyright in the draft specification to OSC, during the 60-day period of review window. The proposal will be sent to Board for approval. Time is not decided yet.  However, there is a potential risk here.  If some company withdraws the IPR during the review period which results in the modification on the specification, it may impact OSC work. The possibility is very minor.
    2. Question is asked on why the IPR claim is not made in the CR time but after the spec. is finished? Answer is that it is specified in the Consititution. Changing the IPR policy will take too much time and all the member companies have to review.
  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.) 

    1. a lot of discussion happend regarding the ONF articles concern raised by John-Paul. Here is the link. 
      1. https://www.sdxcentral.com/articles/news/onf-picks-up-where-o-ran-alliance-falls-short/2020/08/ 
      2. https://www.prnewswire.com/news-releases/onf-announces-new-5g-sd-ran-project-301117481.html
    2. Basically, the feeling from the team is surprise and confusion, including: wording is negative to the work OSC is doing; what is the relationship with O-RAN Alliance? Has anyone been contacted in O-RAN? Does OSC need to respond?
    3. Jinri will bring this to EC and TSC next week.
    4. As for MVP, discussion ongoing. Jinri will follow this.
  8. Status of Open Action Items (Old Business).

    1. O-CU PTL to organize a meeting and invite all the relevant projects (O-DU-HIGH, OAM, RIC etc.) and discuss the cooperation/requirements b/w O-CU and the other projects
      1. see below. discussion combined with item 8b.
    2. O-CU PTL to prioritize the items shown on the presentation slide (https://wiki.o-ran-sc.org/download/attachments/10715432/OSC%20O-CU%20RelC%20-ICT-8.12.pptx?api=v2) to make sure some key features such as handoff could be supported for traffic steering use case.
    3. The team to arrange an offline meeting to further discuss the challenges. Gu Su from China Mobile can help.
      1. Ganesh: Call has been held to discuss the O-CU dependency with other projects. Key point raised: copyright issue for the 3GPP-defined yang model. Not have permission to use 3GPP yang model in OSC. Any development of the node, esp. CU and DU has to be on hold. The definition is from 3GPP; work can not move forward coz of this.

      2. Rittwik: possible to write the code with STUB. With STUB, people could download the code. We do not inject to the repo. Just like ASN.1 issue. We do not get permission from 3GPP. However it did not stopping us from contribution. When permission coming through, we can open it up. Suggest to continue the work on health check. Not to defer to dawn.

      3. Ganesh: Refer to model, generate the code, not to store the yang files in the repo?

      4. Martin: Exactly how we do so far. We implement the code, save it in privie repo (a bit strange in open source community). Not have this code in any nexus, jenkin, whatever internal tool chain for OAM and SIM project. Can do domenstation to be functional. However, avoid generated code from YANG files at the time of being since somebody may think code generation is viewed as modification.

      5. Ganesh: Any common code generation tool across projects?

      6. Martin: No. Netconf servers or clients have their own code gernation for their purpose. Generate code from YANG for API. Avoid put it in nexus, or else where public.

      7. Ganesh agree.

      8. Rittwik: 2nd comment: Currently getting permission from 3GPP is stalled. Who is the LS/coordinator from O-RAN to 3GPP. Can OSC have direct line of comuincationw tiht 3GPP. Is that possible? Suggest Jinri to surface this up to the EC/TSC.

      9.  Jinri: Has the copyright issue been setnt o SDFG before? Old or new issue? Martin answered that it is an old issue. (half an year ago)

      10. Jinri: Later on, we need clear record (of the copyright request/issue in the meeting minute. 2nd, some email from SDFG indictes that ETSI officers are on vacation. Will be back recently and speed up the process. 3rd, Jinri will surface this up to EC/TSC; 4th, we need to push SDFG.

      11. AP: Jinri will bring the copyright issue to TSC/EC (to push the process)
      12. Rittwik: could we have direct line of communication with 3GPP? Jinr: difficult.

        For follow-up, 

      13. AP: Martin will send the written copyright issue description to Jinri and Jack so that Jinri could follow up. Ganesh will also elaborate the copyright issue regarding O-CU and O-DU. 

      14. Ganesh: WG5 also asking t how to handle the YANG model for ODU. Will check with them in the background.

    4. Lusheng to create a wiki page with a template for PTL to fill in the Cherry deliverable summary
      1. Thoralf helped to create the page already. Here is the link: Cherry Release (Dec 2020)
      2. AP: PTL to fill in the goal and the scope first. Will have update once a month.
    5. SMO Project PTL Nominations
      1. voting email has been sent out to TOC. No specific deadline for this. 3 votes already right now. 
      2. Q: if Jack could not make it, can the alternate vote it by email? A: yes. 
      3. Trishan will add the invitation to Lusheng. 
      4. Jinri: expect to get this done by next TOC. 
    6. Trishan to send Jinri the voting process.
      1. done. AP closed.
    7. PTL to provide informaion regarding O-RAN-related open source communities
      1. Jinri emphasized the importance of this request, not because of the AP from TSC/EC, but also beneficial to the whole community. Deadline is set by next TOC meeting. Format is flexbile: slides or simple text in the mail.
    8. Mailing list issue (stop "main" for discussion, use "discussion" list)
      1. Recommendation from LF. It is the best practice not to use "main" list for discussion. Suggest to use a dedicated "discussion" list while using "main" for major announcement in the community. The LF staff could help with the transition and no action is requried from the members.
      2. No opposion to this. No fee is invovled. LF could get this done within one day.
      3. Decision: the OSC will use a dedicated "discussion" list for topic discussion.

  3. Review and Agree to Minutes of Previous Meeting 

    • There is no comment raised on the 0812 meeting minute.

      1. Decision: Moved by David Streibl and seconded by Ganesh Shenbagaraman, without objection and abstention, the 20200812 meeting minute is approved.
  4. Review of Today's Agenda

    • One new items added:

      1. Mailing list issue (stop "main" for discussion, use "discussion" list)
  5. Release Votes and Approval.

  6. Copyright update.
    • No update on this. EC is too busy to process the request. Jinri and Jack will continue to follow; Meantime, the written request by John has already been forwarded to EC and the legal team, waiting for response;

    • John: about A1 spec. the code is already ready, whether waiting for 60 days before releaseing the code needs feedback from O-RAN; JInri understood the issue and will continu to follow; 

  7. O-RAN-related business (marketing, WG interaction, TSC/EC update etc.) 

    • Jinri mentioned that he noticed there was a TIFG-RSAC call on Monday discussing the MVP and asked for any update.

    • Rittwik responded that Koo is writing the minutes. This topic is also discussed in RSAC and he has uploaded the material. The goal is to come up with MVP requirement for TIFG.

    • Jinri asked about the concusion? What MVP should be?

    • Rittwik responded different people have diffrent Ideas. From OSC perspecitive, it is clear. We focus on 3 use cases. Want to validate them. For example for traffic steering, the minimum requriements include UE attachment, get E2 data, do the hand over. That is min. requiremens.

    • OSC should provide min. requirement that TIFG can review. And TIFG should come up with test spec. 

    • Jinri invited Rittwik to to attend the call with WG1-UCTG, WG1 co-chairs and TIFG co-chairs to discuss MVP.

    • JInri asked a question on whether high level requirements are not enough for MVP.

    • Rittwik: Not high level. We had call flow  there.

    • Question from Jinri: do you expect description of the features on certain interfaces?

    • Rittwik: call flows dictate what are the components and interface. If a call flow does not show, then not necessary.  E.g. in O-CU discussion, the E1 interface is not required, then it is not required for traffic steering use case (as a minimum requirement).

  8. Status of Open Action Items (Old Business).

    1. O-CU PTL to organize a meeting and invite all the relevant projects (O-DU-HIGH, OAM, RIC etc.) and discuss the cooperation/requirements b/w O-CU and the other projects

      1. Ganesh indicated that there was already some discussion on this topic in RSAC. MVP was discussed. A concern is raised in that now we are running out of time for cherry. What content to agree for traffic steering use case in terms of E2 messages, lelvel of  CU-DU functionalities etc.. For this Ganesh followed up DU team. They seemed to be ready with message with some already implemented in Bronze release and the others in this release.  Question is about CU: By when to finish the work? Need decision from TOC on how to proceed considering that we do not have enough time to push all the content. How to prioritize?

      2. Rittwik: There is no enough visibility of CU in the wiki (need weekly meting update. Need weekly meeting with others). It is difficulty to track the features. No idea on aligning or misaligned with planning. Suggest to prioritize some features to ensure traffic steering to be realized.

      3. JInri indicated that there was a re-org inside CMCC and the O-CU PTL has moved to other position. the O-CU work is not the major obligation.  We are discussing with a partner company.

          6. A: Not doing SW in OSC which has been developed in ONAP; The OSC coding would be more about use cse side of thing as user advise. Bringing back to ONAP would be powerful;

        2. Presentation by Mahesh Jethanandani

          1. Q: If becoming the PTL, how many resources to bring in?

          2. A: Have contact with OSN, OPENDALYLIGH etc. Could generate enough interest in the group. They would be interest.

    *Quorum: 50% or more of total TOC voting members unless excluded due to attendance.  We have a quorum and can vote on activities.

  3. Review and Agree to Minutes of Previous Meeting 

    1. There is no comment raised on the 0805 meeting minute.

      1. Decision: Moved by Jinri and seconded by David, without objection and abstention, the 20200805 meeting minute is approved.

    2. Jack also mentioned that the history TOC meetings are also archived. The link is at the bottom of the page.

  4. Review of Today's Agenda

    1. No new agenda items raised. Some topics, such as some remaining question regarding the Bronze Maintenance Release, the nomination status etc. will be discussed in old business section (e.g. release note etc.)

  5. Release Votes and Approval.

    1. Jack mentioned that there were a couple of APs last week regarding the Maintainence Rel.

    2. Lusheng responded: one request is from Jinri which is about a summary of changes. That was done. See https://wiki.o-ran-sc.org/pages/viewpage.action?pageId=14221635. Regarding the licensing, 2 ways. One is to manually went through all the updated files to make sure the licensing is ok. Another check is done by Steve from LF. No problem found. Also clarified that O-CU is not in the scope.

    3. Jack: did that address people’s questions to cover the maintenance Release? Any more question? No response.

    4. Motion moved by Lusheng to accept and release the Bronze maintenance release;

      Jinri seconded;

      There was a comment from John-Paul, indicating that he was not on the call last week. Will vote in the dark. Jack indicated that last week John Keeney was the deputy and he did not raised an critical issues. Indeed, he also indicated some updated on NRT RIC in the maintenance release. John is fine with the response.

      ALL the TOC members voted yes. There is no objection/abstaintion.

      Decision: The maintenance release is approved.

  6. Copyright update.
  • Jack: raised the issue in EC meeting, there was a good discussion. EC members are working together to improve the situation. Right now, the copyright is not available to us until after 60 days;
  • Jinri commented that during the EC call, there was a draft proposal which is to provide “draft approval” for the usage of copyright within 60 day window. However, that was just an idea. Still need further confirmation from EC in the future.

 

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

    1. Jinri indicated that this item is not just about marketing. It should be related to many other O-RAN issues. Suggest to change the name to O-RAN-related business (EC/TSC/WG/, marketing etc.);

    2. Jinri indicated recently O-RAN has initated the work on TSC-level minimum viable product (MVP) which is important to OSC’s future planning. Will come back with more information when there is more consolidated result.

    3. Jack also indicated that more representation should be in the RSAC from different companies. All the major companies involved should be part of the RSAC committee. PTL have already been there. Operators should also be there too. So people could understand better. Sometime, two lines of items means 2-year coding. Understanding where the SW is from our standpoint to where we can achieve, the goal is important to their process. RSAC should be involved in the discussion. At least some people. It is daunting to steer through the list of spec. and capabilities for any particular release. Always a lot of opportunity there. Yet what to focus with the limited resource? How to do that? Getting more people involved. RSAC is important.

    4. Lusheng will be leaving on from the assignment from a couple of weeks later, expecting people to step in and help; will be some big gap (lusheng has been doing a lot); need more participation in that space; ATT will participate yet need someone to take leadership there;

  2. Status of Open Action Items (Old Business).

    1. O-CU project to provide O-CU introduction on Cherry planning
      1. O-CU update. See the presentation. https://wiki.o-ran-sc.org/download/attachments/10715432/OSC%20O-CU%20RelC%20-ICT-8.12.pptx?api=v2

      2. Questions are raised on e.g. whether the handover procedure could be supported, how/when the O-CU could be integrated with O-DU-HIGH. Some discussion on this. No conclusion. A suggestion from Jack is to request O-CU PTL to organize a meeting and invite all the relevant projects (O-DU-HIGH, OAM, RIC etc.) and discuss the cooperation. Another suggestion from Rittwik is to prioritize the items shown on the slide to make sure some key features such as handoff could be supported for traffic steering use case. It is indicated that if we wait for the 3GPP O-CU features to be finished and then add on the E2 support, it will be two release late.

      3. AP: O-CU PTL to organize a meeting and invite all the relevant projects (O-DU-HIGH, OAM, RIC etc.) and discuss the cooperation/requirements b/w O-CU and the other projects
      4. AP: O-CU PTL to prioritize the items shown on the presentation slide (https://wiki.o-ran-sc.org/download/attachments/10715432/OSC%20O-CU%20RelC%20-ICT-8.12.pptx?api=v2) to make sure some key features such as handoff could be supported for traffic steering use case.
    2. PTLs to keep Cherry deliverable summary tables up to date
      1. A reminder to make sure work is ongoing. Will go throught the table in the upcoming week;

    3. SMO Project PTL Nominations
      1. Currently there are two nomination from Ericsson and VMWare. The nomination will be open until next week TOC call. After that, the voting will be kicked off.

      2. AP: Jack will talk with Trisan offline to make sure the voting process is right.

      3. Next TOC call, the candidates will be invited to give a short introduction talk.

        1. Matin not here. Alex made the presentation which is on https://wiki.o-ran-sc.org/display/OAM/2020-08-12+OAM+report

        2. There was a question out there relevant to OTF team and Alex is suggested to reach David Kinsey for help.

        3.  Question from David: If go with DECA microseverice, how much of the DCAE needed up and running in the environment for the OSC to be functional? No conclusion/answer to it. Will be discussed in RSAC. In particular, it is also related to the job division b/w SMO, OAM, ONAP.

          David: RSAC this week not holding meeting, rittwik not available. Suggest to hold this question off and line it up after we have the SMO vote to make sure have right people on; Later there will be two RSAC meetings per week. We are already a little behind for the cherry;

        4. Jack: Regarding how to work with other projects, EC is pushing us to enhance the cooperation; would like to make sure RSAC involved in any requirements we asked for. There is a Jira request on our side document that request and how we can use it. Be careful about how much we build requirement for ONAP. Not all the communities are committed to ONAP. Have to make sure the committeement we made. That is why we need more participation in RSAC going forward. Need better job of coordination;

        5.  Tracy: for some of the requirements that are understood, are you meaning creating corresponding jira ticket in the OSC or coross-referencing? Jack: yes. Not want to duplicate things. There is need to record the process so O-RAN can find out what we are relying on them.

    4. Discussion on Cherry
  5. Release Votes and Approval

    1. SMO Vote: Jack: Last week a few people dropped early.  We got 4 in favor 1 abstaining 1 against.  We need to get to 5 votes across TOC even though we had majority present I want to make sure the TOC takes time to work through it and get approval.  We have a standing motion on creating an SMO project brought by Rittwik on the RSAC committee.  Are there further clarifications.
      1. AT&T, Ericsson, NTT DOCOMO, and Nokia voted in favor.  Jinri abstained.
      2. Jinri: I would like to change my vote to Yes.
      3. William from Orange votes in favor.
        1. Vote to add the SMO project to O-RAN SC.
        2. On motion made by Rittwik Jana
        3. Seconded by John-Paul Lane
        4. VOTE: Vote taken, item passed
      4. Jack: We need to add the SMO to wiki and create a repo in gerrit. ActionRittwik Jana add the SMO project to the wiki and gerrit.  
      5. Jack: We will need a PTL.  Looking for people to take on a role as a PTL for the new SMO project.  We should be following Best Practices.  As an interested party anyone can contribute to the project.  Requires an LF ID.  We prefer you use your company's email.  If you want to take a more active role you can offer to be a committer.  There are a small number of committers per project, minimum 2, maximum 5.  The PTL can also be a committer.
      6. You also have to sign the CLA agreement for licensing.  There are two different licenses
        1. Apache license
        2. O-RAN license
        3. For SMO we expect contributions under the Apache license.  We are not under the 3GPP interfaces.  One of the questions asked by EC.  For RIC Near RT controller we have separate applications.  We are going to try to capture these applications as SMO applications and continue to see if that works or we need to separate.  R-Apps under the SMO projects.  We will create a structure that clearly identifies the people.
      7. ActionRittwik Jana start the Principles we will kick the wiki off with these principles.  The RSAC has proposed minimum viable product.  Looking at O-RAN Alliance working groups specifications.  If we don't find specs there then we try to work with them towards the specification so we are not creating throw away code.
    2. Lusheng: Email voting request was sent to the ML on July 9th.  The vote if for 3 procedures and best practices. 
      1. All gerrit code submissions to include at least 1 Jira issue.  This is for tracking purposes.  This creates a Link between gerrit submissions and Jira issues.  
        1. We currently have 3 votes.  Who wants to vote in favor?
        2. Jinri: I thought I already cast my vote via email.  I vote yes.
        3. Jack: I vote yes.
        4. That brings us to 5 votes. 
        5. VOTE: Vote taken, item passed
        6. Lusheng get clarification from LF how to list multiple issue IDs to gerrit. 
        7. Will this be a gerrit pre-check?
        8. Yes, the system will return with a warning message.
      2. License scans are not done until one or two weeks prior to a release.  We require more time.  LF does not scan SCP repos.  That leaves those repos open. LF does have a tool called nexus iq.  People have been using that to do license scans.  Because of the language the security vulnerability may not be helpful for Java but for Go C++ is not as helpful.  Requesting all the repos to add this nexus iq job.  Action item for repo owners is to define a job.  There are samples available for you to follow.Any questions?
        1. On motion made by Lusheng to include a license scan to all repos.
        2. Seconded by Jinri Huang 
        3. Vote taken item passed
      3. Adopting semantic versioning for the artifacts (libraries and docker images and use it for the artifacts).  The action item is for the developers and contributors in the future please use major, minor, and patch versioning.  We can write some best practices in the future but this is the format.  Another action item is what will be the best way to verify a version.
        1. On motion made by Lusheng to include a semantic versioning process to all repos.
        2. Seconded by Jinri Huang .
        3. Vote taken item passed
  6. Copyright updates
    1. No updates on copyrights
    2. Jinri: Zbynek sent an official copyright notification to us. 
    3. Jack: We have an action item that we have to make a proposal to the EC with Stefan but that is still in process.
    4. John-Paul: Is this the 60 day impacts?
    5. Jack: No we were talking about the copyright permission from O-RAN Alliance on any copyrighted material.  The 60 day gets approved by us and we're refining the language for that feature.  That is an alliance issue when the material can be managed copyright material.
    6. John-Paul: Is that resolved?
    7. Jack: Has the 60 day copyright IPR issues resolved?
    8. Action/ Jinri Huang  will check with Zbynek of whether this will imapact.

  8. Status of Open Action Items (Old Business)

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

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

      1. Bronze Maintenance Release
        1. August 1st is the close out date.  I will look to Lusheng to give us a report but I think the progress is less than hoped for in a few areas. 
        2. Lusheng: Status: we have a couple deliverables planned. 
          1. O-DU Low running in the OSC integration lab and completing the O-DU high.  This is lagging behind.  We've been having system related issues. We had 2 dell servers.  For some reason the NIC and FPGA cards do not work right on these two servers.  Later we got the wolf pass servers.  We're having problems installing OS on this server.  It will not make it to this weekend.
        3. KPI-MON xApp flow the near real time xApp team have been trying to build the docker image with other xApps to complete this flow.  There were some problems with the routing. 
          1. Matti: The subscription manager is rejecting the request.  I reached out to the team but have not gotten the response.  The internal communication is working but given the time I am not sure we will deliver.
        4. Additional minor improvements in documentation and the integration repo to upload demo scripts for people to run the demo.
        5. Rittwik: O-DU High is ready to integrate with O-DU Low.  
        6. Lusheng: The O-DU High can follow the future enhancement to move feature code in Bronze release, update their release notes.
        7. John Keeney  We don't see the verification jobs when we release.  I assume there will be full integration tests. I want to know if we can help.
        8. Lusheng; The issue is the base image that your docker file requires has expired on the staging docker registry.  We need to generate that first. 
        9. Henrik Anderson: Will the staging jobs be ready?
        10. Lusheng: The LF has two registrys STAGING and RELEASE.  If it's in the staging registry it will live there for 30 days. Jenkins has a job that will regenerate the newest version of the base image. That image gets refreshed.  It will exist in the staging repo.  The build reference is to the previous version of the base image.  We need to figure out to regenerate.  
        11. Henrik: When we push things to the Bronze branch they don't exist in the staging repo.
        12. Lusheng: Let's work offline.
        13. Jack: We are looking for people who will be interested in Integration and Test.  Lusheng will be reducing his time.  We need more participation in the integration and test area beyond their project.  We need coordination work to have a few more people involved.  
      2. CherryTimeline
    2. Rittwik Jana Requirements Software Architecture Committee

      1. Rittwik: EC has reqested a requirements document for the RAN simulator.  That allows us to socialized with the EC and TOC for bidding for a RAN simulator.
      2. Jack: Any PTL who wants to leverage the simulator beyond planning and generating data should communicate to your their requests and requirements.  Anyone who has needs in that space reach out to Rittwik Jana for the Cherry release.  Since there is a cost associated we want to make sure we're getting everyone's input.
      3. Are all the use cases finalized for Cherry?
      4. Rittwik: Yes, they are in the wiki and lifecycle management for the SMO and the traffic steering and health-check use cases.
      5. Matti: I have new teams that want to contribute to xApps.  I will reach out to you.

  1. The "Zoom Meeting Recording" link under the "2019 05 01" Meeting minutes points to an O-RAN-SC charter PDF instead of the expected .MP4 file

    1. Ranny Haiby  I have updated the link to the correct link.  Thanks for catching!

  2. The "Zoom Meeting Recording" link under the "2019 0515" Meeting minutes points to 2019 0508 meeting recording.MP4 file.


  3. Jun Hyuk Song , I was unable to upload the May 15 recorded zoom meeting.  I opened a trouble ticket.  I'll keep you posted.

  4. I suggest creating one sub page per week to record meeting minutes to prevent scroll overflow of this page.

    1. Viswanath Kumar Skand Priya Yes, All archived minutes are on the side navigation.  This page is reserved for future meetings.

  5. July 3rd 7.2 recording is the same as June 26th.  Actually, Jinri explained meeting results with David & Inspur, and Xiaohua Zhang from Wind River confirmed the cooperation with Inspur on StarlingX. Jack concerned about the relationship between upstream and OSC, suggested Inspur to do work different from upstream in OSC. So it is better to revise it.

  6. gao xian , thank you for bringing the issue to my attention.  I have updated the video file.  The meeting has been archived.  2019 07 03.  Good luck!

  7. Farheen Cefalu

    A few comments on Aug. 7 meeting minute.


    1, throughout the whole minute, it should be "O-RAN" instead of "ORAN";

    2, In New business → POC and Spec investigation from EC discussion: it should be "MWC" instead of "NWC". There are 3 such occurrence. 

    3, In 5.d.3 regarding Ganesh and Alex's AP: it should be ODU instead of ODL;


  8. Farheen Cefalu


    One more comment regarding the Aug. 7 minute.


    On the last AP, the POC could be video, ppt, or live/static demo

  9. Farheen Cefalu


    The numbering of 0828's agenda looks not correct...

  10. the links of recording after the meeting 2020 08 05 are all point to a wrong file.
