IMPROVING THE QUALITY OF LTE NETWORK SERVICES BY CONSIDERING RADIO SIGNAL INDICATORS

DOI: 10.31673/2786-8362.2025.027336

Abstract

This article investigates the impact of key radio signal parameters on
the quality of services delivered in LTE networks. Modern mobile systems rely heavily on the stability of
the radio channel, where indicators such as RSRP and SINR determine data rate, delay, connection stability
and user experience. The study analyses the relationship between these radio parameters and performance
characteristics including Throughput, Ping, POLQA, Call Setup Fail Rate and Call Drop Rate. A multilayer LTE protocol model (PHY–APP) is used to evaluate degradation mechanisms caused by weak signal
and interference. Real measurement data and empirical modelling were applied to determine the influence
of radio conditions on different types of services such as VoLTE, video calls, real-time gaming, live
streaming and TCP-based applications. The obtained results show that reductions in RSRP and SINR lead
to significant drops in data transmission rates, growth of delays and deterioration of voice quality, while
also raising the probability of failed session setup and call drops. Recommendations for improving LTE
service quality through optimisation of radio resource management and base-station configuration are
provided.
Keywords: LTE, RSRP, SINR, QoS, throughput, delay, call drops, VoLTE
