摘　　要：旨在利用移动智能终端研究国内主流3G移动网络的时延性能及用户体验度,提出了端到端的3G移动互联网主动测量方法,设计和实现了适用于Android移动终端的网络测量工具,并针对国内3种3G网络进行了实际网络时延测量实验,分析了Android移动终端访问主流Web网站的时延测量数据。测量结果和数据分析表明,在静态测量和动态测量中,中国电信CDMA2000表现出最好的网络性能,中国联通WCDMA次之,而中国移动的TD-SCDMA则表现出最差的网络性能。研究结果不仅证明了通过移动智能终端进行网络性能评测是可行的,而且可为移动终端用户实现更好的用户体验及网络性能优化提供可行的测量方法和数据支撑。With the proliferation of mobile online-social applications,there has been an increasing growth for accessing the Internet using mobile devices.3G mobile networks provide a convenient approach for users to access the Internet anytime and anywhere.Nevertheless,the performance of 3Gnetworks may significantly impact user＇s quality-of-experience（QoE）.This paper conducted an end-to-end active measurement study of the 3G mobile Internet in China.Due to the largest market share of the Android operation systems,we designed and implemented a wireless network measurement tool in Android,and then performed an evaluation study of three major 3Gnetworks in China using the proposed measurement tool.Our measurement study focused on the delay measurements to popular websites accessed by smart phones.Finally,based on the collected measurement data,we discussed network performance of three different 3Gnetworks in China.Our results show that China Telecom CDMA2000 has the best performance in network delay and delay jitter.This study may provide a feasible measurement approach and data support to achieve better QoE for end users and optimize the mobile wireless network performance.
