Using heterogeneous data sources collected from one of the largest 3G cellular networks in the US over three months, in this paper, the authors investigate the usage patterns of mobile data users. They observe that data usage across mobile users are highly uneven. Most of the users access data services occasionally, while a small number of heavy users contribute to a majority of data usage in the network. They apply statistical tools, such as Markov model and tri-nonnegative matrix factorization, to characterize data users. They find that the intensive usage from heavy users can be attributed to a small number of applications, mostly video/audio streaming, data-intensive mobile apps, and popular social media sites.
