Assessing QoS and User Experience in 4G/5G Networks under Rapid Movement

Abstract

This paper presents an innovative measurement system and a methodology for assessing service quality and user experience in 4G/5G mobile networks during terminal mobility. Weprovide a guide for continuous mobile network measurements with minimal interruptions to signal or data connectivity, yielding complete, gap-free datasets across all communication layers, even in the presence of mobility-induced disruptions. The system integrates diagnostic and telemetry data collection from user equipment with active performance testing of standard Internet protocols. The presented methodology focuses on mitigating data loss during long-term measurements, with particular attention to terminal mobility. Its effectiveness is demonstrated through simultaneous measurements of three mobile operators in urban (Prague) and rural (Jesen´ ık Mountains) areas of the Czech Republic, conducted while vehicles move along city streets, highways, and regional roads. The resulting gap-free datasets, including baseline measurements across key performance metrics, are publicly available in our GitHub repository.
