TL;DR
This study compares VoLTE and non-VoLTE voice calls during mobility, demonstrating VoLTE's faster setup times and significant energy savings through real-world drive tests, highlighting its advantages for mobile network performance.
Contribution
The paper provides empirical evidence of VoLTE's superior performance over non-VoLTE in call setup delay and energy efficiency using real-time drive test data.
Findings
VoLTE reduces energy consumption by approximately 60.76% before the Service Request.
VoLTE calls are 72.6% faster in setup delay than non-VoLTE LTE calls.
VoLTE to non-VoLTE calls are 18.6% faster in setup delay.
Abstract
The optimization of network performance is vital for the delivery of services using standard cellular technologies for mobile communications. Call setup delay and User Equipment (UE) battery savings significantly influence network performance. Improving these factors is vital for ensuring optimal service delivery. In comparison to traditional circuit-switched voice calls, VoLTE (Voice over LTE) technology offers faster call setup durations and better battery-saving performance. To validate these claims, a drive test was carried out using the XCAL drive test tool to collect real-time network parameter details in VoLTE and non-VoLTE voice calls. The findings highlight the analysis of real-time network characteristics, such as the call setup delay calculation, battery-saving performance, and DRX mechanism. The study contributes to the understanding of network optimization strategies and…
