• The primary goal of Non-RT RIC is to support intelligent RAN optimization by providing policy-based guidance, ML model management and enrichment information to the near-RT RIC function so that the RAN can optimize, e.g., RRM under certain conditions.
• It can also perform intelligent radio resource management function in non-real-time interval (i.e., greater than 1 second).
• Non-RT RIC can use data analytics and AI/ML training/inference to determine the RAN optimization actions for which it can leverage SMO services such as data collection and provisioning services of the O-RAN nodes.
• Non-RT-RIC will define and coordinate rApps (Non-RT-RIC applications) to perform Non-RT-RIC tasks.
• Non-RT-RIC will also host the new R1 interface (between rApps and SMO/NONRTRIC services)

D Feature Scope:

• NONRTRIC Functions: (NONRTRIC Release D Wiki)
  
  • Integrated A1 Adapter from ONAP (controller – mediation)
  • Integrated A1 Policy Management Service from ONAP (controller – A1 policies)
  • OSC A1 Enrichment Information Coordinator (controller – A1 EI Job management)
  • OSC Non-RT-RIC Control Panel (GUI – for A1-P & A1-EI Job management)
  • OSC A1 Simulator (a stateful test stub to simulate near-RT-RIC end of A1 interface – A1-P & A1-EI)
  • OSC (initial) APP catalog (for registering/querying APPs)
  • Initial K8S Helm Chart LCM Manager - for APP µServices etc. (ONAP & OSC) (new)
  • Initial Service Exposure Function (new)
• In D Release: (NONRTRIC Release D Wiki)
  
  • Improved A1-PMS NBI (REST & DMaaP) (Rest style alignment)
  • Runtime configuration API (REST) for A1 Policy Management Service (e.g. add/remove adapters, near-rt-rics, security certs, etc)
  • Deployment – Continued improvements for Docker & Kubernetes
  • Extended/Easier deployment options with OSC IT/DEP project (SMO/NONRTRIC deployment)
  • Improving CI/CD to support include A1 Policy controller dependencies from ONAP
  • Multi-version support ( O-RAN A1-AP v1.1, v2.0, v2.1,v3.0 & OSC pre-spec A1)
  • Improved status monitoring/notification of A1-EI Jobs
  • Further improvement in security cert management (All interfaces can now be secured using TLS)
  • Re-architect & improve usability of Non-RT-RIC Control Panel (GUI)
  • Extend NONRTRIC Control Panel to edit/create A1 Enrichment Types/Jobs
  • Extend NONRTRIC Control Panel to configure A1 Policy Management Service
  • Configurable Service Exposure function – Extends/Replaces static exposure gateway in OSC Cherry
  • K8S Helm Chart LCM function for App µServices
  • Update NONRTRIC demo/test environment (one-click tests/use-cases, docker & single/multi-node K8s env)
  • OSC e2e integration use case – O-RU-FH-HelloWorld recovery
    • App to instigate O-RU-FH connection recovery after failure – via O-DU
      • Multiple implementation options – standalone µService and/or deployable ONAP-PF policy script
  • CII badging – Already achieved Bronze/Passing Grade
