Information Coordinator Service

...

(ICS)

The 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 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:

    • Parameters related to delivery (Kafka stream, callback URL etc.). These are different for different delivery protocols.
    • Filtering information (scope, filter or other discriminators).
    • Period-icy
    • Other info used for aggregation

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.

Coordinate/Register Information Types, Producers, Consumers, and Jobs.
Coordinate/Register A1-EI Types, Producers, Consumers, and Jobs (A1 Enrichment Information Job Coordination).

  • Maintains a registry of:
    • Information Types / schemas
    • Information Producers
    • Information Consumers
    • Information Jobs
  • Information Query API (e.g. per producer, per consumer, per types)
  • Query status of Information jobs
  • After Information-type/Producer/Consumer/Job is successfully registered delivery/flow can happen directly between Information Producers and Information Consumers
  • The Information Coordinator Service natively supports the O-RAN A1 Enrichment Information (A1-EI) interface, supporting coordination A1-EI Jobs where information (A1-EI)flow from the SMO/Non-RT-RIC/rApps to near-RT-RICs over the A1 interface.
