Abstract(in English) Customers of NTT DoCoMo's i-mode service have been rapidly increasing and reached to about 36,773,000 customers although the service started only 4 years ago. So, the growing process of i-mode service is an interesting sample to investigate users behaviors. Complex networks as social relations do not have an engineered architecture but instead are self-organized by action of a large number of individuals. From these local interactions, nontrivial global phenomena can emerge and they are known as small-world properties or a scale-free distribution of the degree. In this report, we analyze the relationship between the number of i-mode customers and the volume of traffic, and structure of human relations, about very large set of potential customers of i-mode service, are derived; the structure of human relations is a scale-free network, exponent of degree distribution of the scale-free network is determined from traffic data, and a person having many friends tends to join i-mode service in earlier stage.
