Non-RT RIC (Non-Real-Time RAN Intelligent Controller)
Also known as: Non-Real-Time RIC
The Non-RT RIC is the O-RAN control-loop function embedded in the SMO framework that hosts rApps and drives RAN policy, ML model management and configuration on timescales of 1 s or more, over the A1 interface toward the Near-RT RIC and O1/O2 toward network functions and cloud. It is the anchor for AI/ML-driven RAN automation in Open RAN.

Non-RT RIC in context
The radio access network is the layer where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations, downgrade attacks and jamming, and defenses hinge on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.
To place Non-RT RIC in the wider telecom-security picture, review Near-RT RIC, O-RAN Interfaces (A1, E2, O1, O2), SMO, A1 Interface, O1 Interface and O2 Interface.
