User uniqueness identification is a kind of necessary work for any marketing activity in mobile commerce.However,as a result of many factors and their interactions,it is a common phenomenon for mobile operators that a great amount of mobile users enter communication network and exit.Once users re-enter the communication network,not only the descriptions of old users are totally useless,but also the work of inspecting new users has to be re-started and the whole user profile can only be obtained after a very long time.On the other hand,the accuracy rate of the user identification work based on user information is only 42%.Therefore,the mobile user identification problem is focused after they re-enter the communication network.And a similarity calculation method is presented based on users′network access item and procedure.The method can identify a user by 6steps from pre-processing data → trimming the similar user set→identifying users,etc..Experiments are made on a real data set of the network access log of 25 809 users from a communications corporation in 60 days.The overall accuracy rate of the presented identification method is 98.32%,which shows the feasibility and effectiveness of the method.
