基于TCP数据包层分析的移动互联网用户体验的评估方法

Assessment of Users' QoE for Mobile Internet Based on TCP Packet Layer Analysis

根据现有移动互联网管理体系架构,在网络边缘节点测量的基础上提出了一种基于传输控制协议(TCP)数据包层分析的用户体验评估方法.该方法可适用于单用户粒度,从用户行为以及用户感知两个方面定性和定量评估用户体验.在用户行为评估中,通过分析TCP数据包标志位的交互序列,着重关注网页刷新这一重要行为.在用户感知评估中,通过3套粗细粒度各不相同的计算方法覆盖不同粒度的管理需求,测量结果可最终通过相应的数学模型与平均意见得分值关联.

An assessment method of users' quality of experience( QoE) for mobile Internet based on transmission control protocol( TCP) packet layer analysis is proposed so that the metrics could be measured on the edge node of the mobile internet. This method gathers information from users' behaviors and perceptions,which could be applied to a single subscriber granularity at its best. While doing assessment in users' behaviors,the page refresh incidents should be paid more attention,which is analyzed by the TCP flags of the interaction sequence. On the other hand,users' perceptions indicators could be achieved using three different methods according to various requirements spanning from a coarsest grain perspective to a finest grain perspective,it would be later matched into a QoE mean opinion score( MOS) using the exponential independency model( IQX) of QoE and quality of service.
