rApp

Non-Real-Time RAN Optimization Application

Modular applications hosted on the Non-RT RIC within the SMO that execute automated AI training, radio analytics, and policy orchestration.

Technical Explanation

rApps operate on slower, network-wide timescales to perform strategic optimization. By ingesting massive historical performance telemetry via O1/O2 interfaces, rApps detect chronic interference patterns, train federated machine learning models, dynamically reallocate spectrum across slices, and feed updated inference policies to edge xApps via the A1 interface.

Key Functions

  • Strategic network-wide optimization operating on timescales >1 second
  • Training and retraining machine learning models using centralized telemetry lakes
  • Autonomous cell sleep-mode scheduling slashing nationwide network energy consumption
  • Automated root-cause analysis of dropped connections and SLA degradations
  • Feeding declarative A1 policy constraints to real-time edge controllers
