The O-RAN SC’s RIC (RAN Intelligent Controller) is an open-source container-based implementation of the RIC concept and protocol specifications as standardized by the O-RAN alliance. Its second half-yearly release is almost ready and targeted for June 2020.

This presentation will focuses on the capabilities added in the second release after giving an overview of the RIC. This release includes (1) significant changes when adapting the base E2AP implementation from pre-specification assumptions to the first version approved by the O-RAN alliance, (2) supporting newly O-RAN specified E2 SMs (service models) like the NI (network interface) SM and KPIMON SM providing E2 nodes, like a gNB, a way to report interface messages & KPIs, and to change E2 node behaviour via NI policies, (3) changes in the API to be used by RIC xApps, (4) support for the O-RAN O1 management interface, and (5) support for the O-RAN A1 policy steering interface between the management system and the RIC.
