摘要

本研究旨在提出体验质量(QoE)模型,并假设用户的感知可能会随着技术的变化而变化。因此,24名受试者采用在线问卷形式参与。建立了时延和抖动的QoE模型。将获得的模型用于评估泰国的4G和5G网络,发现曼谷的5G网络性能优异,而4G网络性能一般或较差。本研究中时延和抖动的平均Mean Opinion Score (MOS)结果分别为4.48和4.54,而4G网络时延和抖动的结果分别为3.80和3.22最大值。本研究的MOS结果很容易被一般用户理解。因此,本文所展示的创建模型的概念可以扩展到其他QoS参数。

Proposed QoE Models Associated with Delay and Jitter Using Subjective Approach and Applications for 4G and 5G Networks
This study aims to propose the Quality of Experience (QoE) models with the assumption that users’ perception may vary according to the technology changes. Therefore, 24 subjects participated by using an online questionnaire form. The QoE models for delay and jitter were created. The obtained models were applied to evaluate 4G and 5G networks in Thailand and found that 5G networks in Bangkok have excellent performance while 4G networks have fair to poor performance. The average Mean Opinion Score (MOS) results referring to delay and jitter in this study are 4.48 and 4.54 respectively, whereas the results from 4G networks referring to delay and jitter is 3.80 and 3.22 maximum respectively. The MOS results from this study can be understood by general users easily. Thus, the concept to create models as shown in this paper can be extended to the other QoS parameters.
