Coordinates


The Non-RealTime RIC (RAN Intelligent Controller) is an Orchestration and Automation function described by the O-RAN Alliance for non-real-time intelligent management of RAN (Radio Access Network) functions. The primary goal of the NONRTRIC is to support non-real-time radio resource management, higher layer procedure optimization, policy optimization in RAN, and providing guidance, parameters, policies and AI/ML models to support the operation of near-RealTime RIC functions in the RAN to achieve higher-level non-real-time objectives. NONRTRIC functions include service and policy management, RAN analytics and model-training for the near-RealTime RICs. The non-RealTime RIC project provides concepts, specifications, architecture and reference implementations as defined and described by the O-RAN Alliance architecture.

The NONRTRIC implementation will communicate with near-RealTime RIC elements in the RAN via the A1 interface. Using the A1 interface the NONRTRIC will facilitate the provision of policies for individual UEs or groups of UEs; monitor and provide basic feedback on policy state from near-RealTime RICs; provide enrichment information as required by near-RealTime RICs; and facilitate ML model training, distribution and inference in cooperation with the near-RealTime RICs. 

As shown in the Component Architecture diagram below, the NONRTRIC exists within the ONAP eco-system, leveraging existing infrastructure to support non-realtime control of the RAN (Radio Access Network).

All implementations will be demonstrated in open community labs to prove functionalities and to give feedback to the O-RAN working groups.

Integration into ONAP

In the meeting from 2019-08-12 we clarified the expected integration of ONAP and OSC OAM/NONRTRIC functionality. Note the O1 and A1 interfaces and protocols.

      A newer version of the proposal is now available:

    Tracy Van Brakle , I am going to move the Non-real-time RIC pages into their own Space.  The space will be called Non-real-time RIC (NRTRIC).  You will be able to access these pages from the Projects link in the top navigation bar above.  I opened a ticket with LF to move these pages to that space.  Let me know if you agree with this. These pages are a good start.  Thank you!

    Hello,

    I would like to know more about the R-APP and R-APP coordinator in Non-RT-RIC. What is the functionality it is supposed to perform? Is there any relation with x-APP in Near-RT-RIC? How it is going to be realized in ONAP?

    1. John Keeney

      Hi Arindam. We are currently working through some internal discussion on this. I will revert to the community when I have more detail. Thanks.

        Hello John Keeney,

        Thank you for your reply. 

        Also it would be wonderful If you could provide more details on implementation of A1 Policy Management Service in ONAP. Is there any discussion ongoing in community?

        I'm following this page: Release A

        1. John Keeney

          Hi Arindam.

          The A1 Policy Management Service is not implemented in ONAP. It is implemented here in OSC as part of this NONRTRIC project. The documentation and code is available here in our gerrit repo (nonrtric), the generated docs, and the intro given the Release A page.

          Thanks.

            Hello John,

            According to the above "integration to ONAP architecture" , ONAP is going to play the role of NON-RT-RIC. In that case it also needs to implement the policy management function( which is already developed by OSC) in ONAP.

            Is there any plan to integrate the policy management agent code to ONAP? If that is the case then which module in ONAP is going to play the role.

            1. John Keeney

              Hi Arindam.

              ONAP most definitely plays a major role in the current OSC NONRTRIC work since ONAP forms the basis for the current OSC SMO.

              It is unclear if an A1 Policy Management Service is needed in ONAP. This is currently being discussed as part of the scoping discussions between ONAP and OSC.
              If an A1 Policy Management Service is required in ONAP we may consider proposing to upstream or maybe re-home this component into ONAP in the Guilan timeframe.

              The current OSC A1 Policy Management Service can be executed as a DCAE microservice.

              I invite you to join any discussions about the need for an A1 Policy Management Service in ONAP vs OSC, or alternatively using the released OSC service in ONAP. Any contribution from yourself or Samsung would be more than welcome.

              Thanks.
              John

                Hi John,

                Thank you for your invitation to join community meeting. We will deifinitely try to attend those meeting and have discussion.
