document: An experimental study of large-scale mobile social network Mobile social network is a typical social network where one or more individuals of similar interests or commonalities , conversing and connecting with one another using the mobile phone . Our works in this paper focus on the experimental study for this kind of social network with the support of large-scale real mobile call data . The main contributions can be summarized as three-fold : firstly , a large-scale real mobile phone call log of one city has been extracted from a mobile phone carrier in China to construct mobile social network ; secondly , common features of traditional social networks , such as power law distribution and small diameter etc , have been experimented , with which we confirm that the mobile social network is a typical scale-free network and has small-world phenomenon ; lastly , different from traditional analytical methods , important properties of the actors , such as gender and age , have been introduced into our experiments with some interesting findings about human behavior , for example , the middle-age people are more active than the young and old people , and the female is unusual more active than the male while in the old age .
