VIAVI L3

This rApp reconstructs Layer 3 (RRC/NAS) signalling messages from call trace event records, reassembling protocol-level message sequences per subscriber session. It exposes decoded signalling flows to operations teams, enabling rapid root-cause analysis (RCA) of call failures, handover issues, and service degradations without manual trace correlation. By automating extraction and decoding of L3 messages, the rApp reduces mean-time-to-resolution for network incidents, supports proactive fault detection, and improves visibility into UE-to-network interactions across the RAN. It integrates with existing call trace pipelines, requiring no additional probes, and scales to high-volume trace ingestion for continuous monitoring and troubleshooting workflows.
