Information regarding Release C for Non-Realtime RIC will be in this page.

Architecture for Release C:

NONRTRIC Architecture - Cherry

NONRTRIC components:

Non-RT RIC Control Panel/ NONRTRIC Dashboard
Policy agent / A1 Policy Management Service
Enrichment Information Coordinator
R-app Catalogue
SDNC A1 Controller
Near-RT RIC Simulator

The code base for "Cherry" Release is in the NONRTRIC, NONRTRIC-ControlPanel, and A1-Simulator, source repositories (Gerrit) - Cherry Branch

Non-RT RIC Control Panel / NONRTRIC Dashboard

Graphical user interface

View and Manage A1 policies in the RAN (near-RT-RICs)
Interacts with the Policy agent’s NBI (REST API)
Graphical A1 policy creation/editing is model-driven, based on policy type’s JSON schema
View and manage producers and jobs for the Enrichment coordinator service
Implementation:
- Frontend: Angular framework
- Backend Java Springboot application
- Repo: portal/nonrtric-controlpanel

Please refer this developer guide to set up in your local environment. More information about Non-RT Ric control panel can be found here.

**A1 Policy Management Service (from ONAP CCSDK – Guilin)**

The A1 Policy Management Service is a microservice which maintains a transient repository of:

All configured A1 policies instances in the network.
All NearRT RICs in the network.
All Policy types for all Near-RT-RICs
All configured Policy instances in the network
(Optionally deploy without A1 Adaptor to connect direct to near-RT-RIC)

It provides :

Unified REST & DMAAP APIs for managing A1 Policies in all near-RT-RICs
Synchronized view of policy instances for each R-APP (soon)
Synchronized view of policy instances in all near-RT-RICs
Synchronized view of policy types in all near-RT-RICs
Policy Query API (e.g. per near-RT-RIC, per R-APP (soon), per policy type)
Unified nearRTRIC-ID to nearRTRIC-address mapping (e.g. can include mapping to A&A1, CMDBs etc to “find” near-RT-RICs - soon)
Placeholder “O1 ManagedElement” mapping database interface to find appropriate near-RT-RIC to address A1 operations for required RAN elements (e.g. connection to A&AI, RuntimeDB, other CMDBs etc - soon)
Monitors all near-RT-RICs and recovers from inconsistencies (multiple strategies - soon) – e.g. near-RT-RIC restarts
Support for different Southbound connectors per near-RT-RIC – e.g. different A1 versions, different near-RT-RIC version, different A1 adapter/controllers supports different or proprietary A1 controllers/EMSs

A1 Enrichment Information Job Coordination Service

Coordinate/Register A1-EI Types, Producers, Consumers, and Jobs.

Maintains a registry of:
- A1-EI Data Types / schemas
- A1-EI Producers
- A1-EI Consumers
- A1-EI Jobs
A1-EI Query API (e.g. per producer, per consumer, per types)
Query status of A1-EI jobs
Monitors all near-RT-RICs and recovers from inconsistencies

After EI-type/Producer/Consumer/Job is successfully registered delivery/flow can happen directly between A1-EI Producers (in SMO/NONRTRIC domain) and A1-EI consumers (near-RT-RICs in RAN domain)

(Initial) R-APP catalog

Register for R-APPs

First step towards R-APP management in NONRTRIC
R-APPs can be registered / queried

More work required in coming releases as the R-APP concept matures

**Controller / OSC A1 Adaptor (from ONAP CCSDK – Guilin):**

Mediation point for A1 interface termination in SMO/NONRTRIC

Implemented as OSGI Feature/Bundles
A1 Rest southbound
NETCONF YANG Northbound
RESTCONF > NETCONF adapter
Mapping logic / Provider
Can be included in an any SDNC/CCSDK persona

https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric/en/cherry/

Near-RT-RIC Simulator:

Stateful A1 test stub

Used to create multiple stateful A1 providers (simulated near-RT-RICs)
Implemented as a Java Springboot application
Swagger-based northbound interface, so easy to change the A1 profile exposed
