【摘要】：随着3G和LTE网络的建设,移动互联网业务得到迅速普及的同时,其业务传输质量也有了质的提升,而在移动互联网向用户提供了丰富的业务选择同时,也降低了传统电信网络所培养的用户的忠诚度。如何保障和提升用户的业务体验(QoE, Quality of Experience)已成为电信运营商非常重视的课题。目前,QoE方面的研究更多地关注于传统QoS参数在反映用户业务体验方面的不足和完善上,例如同样误码率信道环境下,关键视频帧上的误码会明显恶化用户体验。然而,除了信道传输的质量保障外,作者发现用户端智能手机性能的参差不齐也会在一定程度上影响到用户的业务体验,而目前还极少有文献涉及这方面的研究。本论文主要关注智能手机终端性能对于QoE反馈系统的影响,并对基于终端性能参数反馈的QoE模型矫正进行研究。首先,本论文通过对数十款不同厂商生产的不同配置的智能手机进行性能测试,发现终端性能对于业务质量参数确实存在明显影响。然后,针对业务网络质量最敏感的流媒体业务,搭建了模拟传输系统,通过在系统上进行不同传输质量信道的配置,进一步验证了智能手机终端性参数能对于QoE评价体系所产生的影响。其次,在模拟实验结果分析基础上,结合当前国内外研究组织所研究的QoE用户体验质量反馈研究成果,提出了一种QoE反馈模型,并通过层次分析的方法建设性地将用户一侧的智能手机终端性能融入到了QoE评价体系当中。最后,根据本论文提出的基于智能手机性能参数的QoE反馈模型,提出了在现网中,根据用户所使用的智能手机的性能参数,对用户端业务QoE主观分级评价进行修正的机制。
[Abstract]:With the construction of 3G and LTE networks, mobile Internet business has been rapidly growing in popularity at the same time, the transmission quality has been a qualitative improvement, but in the mobile Internet to provide users with a wealth of business at the same time, but also reduces the traditional telecommunication network to cultivate user loyalty. How to protect and enhance the service experience of users (QoE Quality, of Experience) has become the telecom operators is very important. At present, the research of QoE pay more attention to the traditional QoS parameter in reflecting the user experience of business problems and improve, such as the same BER channel environment, error key frame of the video will be significantly worse user experience. However, in addition to ensure the quality of the transmission channel, the author found that the user terminal intelligent mobile phone uneven performance will to some extent affect the user's business experience, but there is little literature To offer the research. This thesis mainly focuses on the intelligent mobile phone terminal for QoE performance feedback system, and studied the correction model of QoE feedback terminal based on performance parameters. First, this paper tested by log ten different manufacturers of smartphones with different configurations of the machine, it is found that terminal performance does exist impact on the quality of service parameters. Then, according to the most sensitive service quality of network streaming media service, build the simulation transmission system, through different channel transmission quality on the system configuration, to further verify the intelligent mobile phone terminal can be generated for the QoE parameter evaluation system. Secondly, on the basis of the experimental results in simulation analysis and combined with the current domestic and foreign research organization of the QoE user experience feedback on the quality of research results, proposes a QoE feedback model, and through the hierarchy The construction method analysis of the smart mobile phone terminal side of the performance of the user into the QoE evaluation system. Finally, based on the intelligent mobile phone based on the performance parameters of the QoE feedback model is proposed in this paper, put forward in the current network, based on the intelligent mobile phone users use the performance parameters, evaluate the modified mechanism of the client business QoE subjective ratings.
