多媒体业务QoE \QoS相关模型综述

Survey on QoE\QoS Correlation Models For Multimedia Services

Mohammed Alreshoodi, John Woods

摘要:

本文简要回顾了现有的一些相关模型,试图映射服务质量(QoS)的多媒体服务的体验质量(QoE)。术语QoS指的是确定性的网络行为,以便数据可以以最小的丢包、延迟和最大的带宽进行传输。QoE是一种涉及人的维度的主观度量;它将用户对应用和网络性能的感知、期望和体验联系在一起。主观测量的圣杯是从客观测量中预测它;换句话说,从给定的QoS参数集预测QoE,反之亦然。虽然存在许多用于多媒体的质量模型,但它们中的大多数仅是从给定QoS预测QoE的部分解决方案。这篇文章分析了许多以前的尝试和优化技术,可以可靠地计算加权系数的QoS/QoE映射。

英文摘要:

This paper presents a brief review of some existing correlation models which attempt to map Quality of Service (QoS) to Quality of Experience (QoE) for multimedia services. The term QoS refers to deterministic network behaviour, so that data can be transported with a minimum of packet loss, delay and maximum bandwidth. QoE is a subjective measure that involves human dimensions; it ties together user perception, expectations, and experience of the application and network performance. The Holy Grail of subjective measurement is to predict it from the objective measurements; in other words predict QoE from a given set of QoS parameters or vice versa. Whilst there are many quality models for multimedia, most of them are only partial solutions to predicting QoE from a given QoS. This contribution analyses a number of previous attempts and optimisation techniquesthat can reliably compute the weighting coefficients for the QoS/QoE mapping.
