Primary Goals:- 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)

E Feature Scope: - E Release Priorities:
- ONAP Control Loop -> O-RAN rApp : “The rApp-ification of ONAP Control Loops”
- Adopt ONAP CL work as a starting point, continue to identify gaps, then extend
- Identify & motivate where an rApp is different from a CL
- Types of rApps:
- Microservice-based rApps
- Non-Microservice-based rApps
- NONRTRIC Service Exposure/Gateway -> O-RAN R1 : “The R1-ification of Service Exposure”
- Service-independent aspects
- Types of exposure support in R1:
- Microservice-based rApps & Service
- Non-Microservice-based rApps & Service
- Use cases of rApps & Exposing specific Services via R1
- Requirements drivers & demonstrators
- O-RU FH recovery (multiple), O-DU Slice Assurance (multiple), Existing Function Tests, various other use cases in ONAP
- Continued Evolution & Support for A1 functions
- NONRTRIC Functions:
- Integrated A1 Adapter from ONAP (A1 Policy (A1-P) controller – mediation)
- Integrated A1 Policy Management Service from ONAP (A1 Policy (controller – A1 policiesA1-P) controller)
