Practical QoS measurement and analyzes on a 5G non-standalone architecture
Main Article Content
Abstract
Fifth Generation (5G) networks are becoming the standard in the global telecommunications industry and are becoming a permanent part of everyday life. As mobile network operators have commenced to publicize the implementations of their 5G networks, measurements are not frequently used to demonstrate the actual aspects of these networks' capabilities.This article presents an actual 5G architecture based on the 5G Option 3x reference model, together with findings from Quality of Service (QoS) testing. The outcomes are compared to our actual hands-on measurements of the 4G network in addition to being compared to the expectations for the 5G network. Based on examination of the 5G testbed results, 5G performed much better than 4G in all fundamental QoS, including up- and downlink throughput, latency, packet error rate and jitter. Additionally, practical measurement results on this non-standalone 5G architecture demonstrate that latency and jitter are not greatly impacted by the load on the cell or the core network provided traffic preferences are set up correctly. The study of QoS and a first performance assessment of 5G, along with the identification of application-level performance concerns, are the paper's main conclusions. These results underline the necessity of validating and testing generic 5G services and applications through fair benchmarking approaches.
