Rapid, Continuous, Per-UE Traffic Steering on the Near-RT RIC: Executing in Sub-Second Cycles
Sub-Second Per-UE Traffic Steering xApp
Operating at the Near-RT RIC on a 10 ms–1 s control loop, the Traffic Steering xApp continuously ingests live E2 measurements and executes per-UE steering decisions in real time. Every PRB reading, every RSRP update, every RRC state change, the xApp re-evaluates and acts. Where the rApp works on the minute-to-hour horizon, the xApp lives in the sub-second world, keeping traffic balanced as conditions change.
10 ms–1 s control cycle, the xApp reacts to live E2 measurements as they stream in, re-evaluating every cycle with no offline waits.
Acts on individual UEs, not aggregate cell state. Per-UE decisions fuse RSRP, RRC state, and 5QI into real-time steering actions.
Ingests streaming RAN telemetry over E2 and re-evaluates every cycle: no batch windows, no stale views of the network.
The DRL engine runs in real time at the RIC edge, producing steering actions every cycle without hitting offline compute.
"Every cycle. Every UE. Every millisecond: the RAN reacts as fast as the network changes."
– Traffic Steering xAppSub-second, continuous, per-UE steering at the Near-RT RIC edge
Complete Analyze → Decide → Act within a single Near-RT control cycle, from milliseconds to under a second.
Generates per-UE cell-association and handover actions, not cell-wide policies, for precise, targeted control.
Lightweight DRL agent optimized for real-time inference at the Near-RT edge, decisions produced every control cycle.
Continuous ingestion of RSRP, SINR, PRB utilization, and RRC state directly from the RAN over the E2 interface.
Decisions factor in cell type, QoS/5QI profile, and link quality simultaneously, not just one dimension.
Re-evaluates the full UE population every cycle: no stale decisions, no waiting for the next batch.
Runs inside the Near-RT RIC as a true closed-loop xApp, O-RAN compliant by design.
Sub-second, per-UE, radio-aware steering, continuous closed loop at the Near-RT edge
A 10 ms–1 s control loop executing UE-granular steering, the xApp reacts to live RAN state the instant E2 measurements arrive. Every cycle re-evaluates the full UE population, so decisions stay aligned with real-time conditions.
Decisions fuse RSRP, SINR, cell type, and 5QI/QoS profile in real time, so steering respects both link quality and service intent. UEs get routed to the right cell for their specific radio conditions and service class, not a one-size-fits-all target.
The same Deep Reinforcement Learning family powering the rApp, optimized for sub-second execution at the RIC edge. Continuous online inference: no offline batch windows, so the xApp produces reliable steering actions on every Near-RT control cycle.
Analyze → Decide → Act on every Near-RT cycle. Outcomes feed straight back into the next decision: built-in stability guards prevent thrashing, so the xApp stays responsive without over-steering.
Run rapid, continuous, per-UE traffic steering at the Near-RT RIC: sub-second decisions from live E2 telemetry, executing as fast as the RAN changes.
