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 (Release H)

Configurable mediators to take information from DMaaP (& Kafka) and present it as a coordinated Information Producer
