Following the opening of the telecommunication business, the market offers a lot of business models in conformity with the users’ demand, enabling users to choose the suitable service in accordance with the personal demand. Although the services offered by the Type II telecommunication business are similar to the Type I telecommunication business, the Type II telecommunication service providers can quickly respond the market demand. The most common response is to reduce the price while the cost is reduced. Generally speaking, because of the market competition users can buy more services with cheaper price. Relating to the rate structure of Type I business, users can buy the same services with cheaper price, generally called “Saving Money” on the market. This thesis discusses mainly on how to classify users Call Detail Record (CDR) to find out the relationship between users and agents, the behavior of users, similar user’s possible behavior and so on. This thesis applies the self-organizing map model to clustering CDR and to analyzing the CDR.
