  • Patent number: 7194256
    Abstract: A method of creating individual information including a call log is provided. After the individual information is created through a mobile terminal, determining an operation mode of the mobile terminal if storing of the individual information is requested. Inserting a current call log into the individual information if the operation mode is a call mode. Storing the individual information with the call log inserted therein. Thus placing the call log in an organic conjunction with the individual information. Since automatic dialing and transmission of a short message or an e-mail can be carried out using the individual information, the mobile terminal becomes more user-friendly and the utilization of individual information stored in the mobile terminal is increased.
