Understanding the traffic characteristics of mobile network is important for Intemet service providers （ISPs） to optimize network resources. In this paper, we conduct a detailed measurement study on the hyper text transfer protocol （HTTP） traffic characteristics of cellular network among different operating systems （OSs） as well as different device-types. Firstly, we propose a probability-based method to identify the installed OS of eacb smartphone. Then we analyze the traffic characteristics of these smartphones in terms of OS and device-type based on a dataset across 31 days （a billing cycle）. Finally, we identify the installed apps of each smartphone and compare the usage of apps on the dimensions of OS and device-type. Our measurement study provides insights for network operators to strategize priciag and resource allocation for their cellular data networks.展开更多
