Status (3-1-21): 

Mission: Better manageability of, for example, E2 connections, the RIC platform as well as xApps via the xApp frameworks.

Primary Goals: Support operator-initiated health-check via E2 and be able to close all current or reject all future E2 connections. More manageability of the RIC platform and xApps, including, for example, platform statistics from E2 and A1 and more capabilities in the language-specific xApp frameworks and SDL (shared data layer).

Drelease highlights (2020-12-01): 

Status 2020-12-11:

• The primary goal of Non-RT RIC is to support intelligent RAN optimization by providing policy-based guidance, ML model management and enrichment information to the near-RT RIC function so that the RAN can optimize, e.g., RRM under certain conditions.
• It can also perform intelligent radio resource management function in non-real-time interval (i.e., greater than 1 second).
• Non-RT RIC can use data analytics and AI/ML training/inference to determine the RAN optimization actions for which it can leverage SMO services such as data collection and provisioning services of the O-RAN nodes.
• Non-RT-RIC will define and coordinate rApps (Non-RT-RIC / SMO appliciations) to perform Non-RT-RIC tasks.
• Non-RT-RIC will also host the new R1 interface (between rApps and SMO services)

D Feature Scope:

• Demo available at: 2020-12-04 - OSC NONRTRIC Cherry Demo

Primary Goals:

• support of the application LCM use case
