Lab: Analyze handover KPIs and identify failure cause

KPI-Based Handover Analysis

Network operations teams monitor handover KPIs to identify and fix mobility problems before they affect user experience. The key metrics include Handover Success Rate (HOSR) which should exceed 95%, Preparation Failure Rate measuring issues during the negotiation phase, Execution Failure Rate measuring radio-layer failures during the switch, Ping-Pong Rate tracking unnecessary back-and-forth handovers, and Handover Interruption Time measuring the data gap duration. Each KPI points to specific root causes.
