Mobility analysis: handover delays and ping-pong

Analyzing Mobility Performance

Mobility analysis examines how the network manages cell transitions as the UE moves through the coverage area. Key metrics include handover success rate (target above 98%), handover execution time (the interruption duration — typically 30–80 ms for intra-frequency LTE, 50–150 ms for NR), and handover failure rate. Plot all handover events on the map with color coding: green for successful, red for failed, yellow for ping-pong. Cluster analysis reveals whether failures concentrate at specific boundaries — a cluster of red dots between two cells indicates a systematic handover problem requiring…
