Summary
Primary Goals for Non-RealTime RAN Intelligent Controller (Non-RT-RIC)
|
Overall objective for the F ReleaseIn the F Release we focus mainly on prototyping building blocks to support Non-RT-RIC Apps ("rApps") and R1 interface concepts from O-RAN. For the R1 interface we will focus on enabling Service Management & Exposure (R1-SME), and demonstrating Data Management & Exposure (R1-DME). |

Information Coordinator Service (ICS)
A service that coordinates Information Jobs, producers and consumers. Also acts as an A1 Enrichment Information Controller.
ICS is a data subscription service which decouples data producers from data consumers. A data consumer can create a data subscription (Information Job) without any knowledge of its data producers (one subscription may involve several data producers). A data producer has the ability to produce one or several types of data (Information Type). One type of data can be produced by zero to many producers.
A data consumer can be an R-App using R1 APIs, or a near-RT RIC using the A1-E API (where the subscribed data is more specifically called "Enrichment Information").
A data consumer can have several active data subscriptions (Information Job). One Information Job consists of the type of data to produce and additional parameters, which may be different for different data types. These parameters is not defined or limited by this service and may for instance include:

APIs provided by the ICS service
A1-EI
This API is between Near-RT RIC and the Non-RT RIC. The Near-RT RIC is a data consumer, which creates Information Jobs to subscribe for data. In this context, the information is referred to as 'Enrichment Information', EI.
Data producer API
This API is provided by the Non-RT RIC platform and is intended to be part of the O-RAN R1 interface. The API is for use by different kinds of data producers and provides support for:
- Registry of supported information types and which parameters needed to setup a subscription.
- Registry of existing data producers.
- Callback API provided by producers to setup subscriptions.
Data consumer API
This API is provided by the Non-RT RIC platform and is intended to be part of the O-RAN R1 interface. The API is for use by different kinds of data consumers and provides support for:
- Querying of available types of data to consume.
- Management of data subscription jobs
- Optional callback API provided by consumers to get notification on added and removed information types.
Service status
This API provides a means to monitor the health of this service.
DMaaP/Kafka Information Producer Adapters
Configurable mediators to take information from DMaaP (& Kafka) and present it as a coordinated Information Producer
...
- A version implemented in Java (Spring) - Supporting filtered DMaaP and Kafka mediation:
- A version implemented in Go - Supporting DMaaP mediation:
(Initial) NONRTRIC APP catalog
Register for NONRTRIC APPs

A1 Policy Controller / Adapter (from ONAP CCSDK – Istanbul)
Optional mediation point for A1 Policy interface termination in SMO/NONRTRIC
...
Near-RT-RIC Simulator
Stateful A1 test stub
- Used to create multiple stateful A1 providers (simulated near-rt-rics)
- Supports A1-Policy (A1-P) and A1-Enrichment Information (A1-EI)
- Implemented as a Python application
- Swagger-based northbound interface, so easy to change the A1 profile exposed (e.g. A1 version, A1 Policy Types, A1-EI consumers, etc)
- All A1-AP versions supported
Call-out feature to add applications-specific A1-Policy behaviors (REST & Kafka call-outs supported)
