On statistical social behaviors from millions of cell phone users

Limited knowledge on the social laws for cell phone users is known due to the lack of public call data. In this paper, we collected data regarding more than 20 million users of the China Telecom Corporation and analyzed the power-law distribution and their social behavior laws. Two power-law distributions that exist in the distribution of degree and user contacts are found in the study of the users' behaviors, and we analyzed the conclusions drawn from the study. Also, we studied the users' social patterns based on the users' age difference, and analyzed user's social behaviors from the user's age, gender, social scope, time and other aspects.
