Summary: 
In this paper, we investigate the universal structure of social networks by focusing on the power laws that appear in the data of actual communication services. In explaining the reasons that underlie the power laws with selfconsistent way, we elucidate the whole universal social network structure. Since the power laws examined in this paper describe the relations present in coarse data, detailed behaviors (e.g. who is communicating with who) of each user cannot be observed. However, we can extract a universal structure that is independent of the superficial structures present in each data set.
