【摘要】 近几年来,随着移动互联网的蓬勃发展,移动互联网领域不断涌现出各种各样的新业务,比如微博、微信等。现今越来越多的人利用移动互联网业务来提高工作和学习的效率,改善娱乐和生活的质量。随着对移动互联网依赖性的不断增加,人们对业务的服务质量以及用户体验质量也有了越来越高的要求。为了提高业务质量,满足人们的使用需求,对业务的服务质量进行监测十分必要的。论文首先对目前移动互联网业务质量监测相关的理论基础进行了概要总结,包括研究现状,研究范围和内容,以及相关的监测技术等方面的内容。其次介绍了iOS平台体系结构以及其主要的开发技术。由于移动互联网业务一般是以应用程序的方式安装中手机终端上的,因此对这类业务进行监测应该采用被动监测方式。依托实验室中心研制的端到端互联网质量监测系统以及对iOS平台运行原理的研究,论文在iOS平台上设计了移动互联网业务质量终端监测程序。为了验证质量监测程序在实际网络环境中的性能,通过分析移动互联网社交业务的通信机制,从用户的角度出发,论文提出了一组针对社交业务的QoE指标,这组指标能够直接反映用户使用相应业务时的体验感知。并通过结合QoS和QoE进行分析,总结出了这组指标的计算方法。在此基础上,论文分析了目前移动互联网比较重要的微博和微信业务的流量,提取出了它们的应用识别和用户操作行为的识别方法。并在实际的网络环境下,以微博和微信为例,利用监测程序对这组指标进行了监测实验。实验表明,这组指标能较好的反映用户使用社交应用时的真实体验。更多还原

【Abstract】 In recent years, with the rapid development of mobile Internet,mobile Internet field emerg out of a variety of new services, such as Micro blog, Micro message. Nowadays,more and more people use mobile Internet services to raise the efficiency of work and learning, and improve the quality of life and entertainment. With the increasing dependence on mobile Internet, peoplehas also been increasing demands on the service quality and user experience quality. In order to improve the quality of service to meet people ’s needs, it’s necessary to monitor the quality ofnetwork service.Firstly, this thesis briefly summarizesthe theoretical basis on the service quality monitoring of mobile Internet, including research status, scope and content, and related monitoring technology and other aspects. Secondly, it introduces the iOS platform architecture and its main development technologies. As the mobile Internet business installed on the mobile terminals as a general native application, this kind of business should be monitored by using passive monitoring mode. Relying on the End to End Network Monitor System developed by the laboratory center,and the study of operational principle of iOS platform, the thesis designs and implements a mobile Internet service quality monitor module on the iOS platform. In order to verify the performance of quality monitor module in the actual network environment, through analyzing the communication mechanism of mobile Internet social business, this thesis presents a group of QoE indicators for social services from the user’s experience perception perspective. Then,through combine QoS and QoE to analyzing, it summeds up the calculation method of the group of indicators. On this basis, the thesis analyzes the traffic of Micro blog, Micro message business, and extracted out the recognition characteristics of the applications and user behaviors. Afterwards, in the actual network environment,the thesis uses the monitor module to calculate the group of indicators. The results show that this set of indicators can better reflect the real user experience when using social applications.更多还原
