Method for converting address data for mobile telephone different standard of address book

A method for converting address data of a mobile terminal with a different address list standard is provided to allow mobile terminals manufactured by different manufacturers to transmit and receive address data. A mobile terminal is connected for infrared ray communication with the other mobile terminal through an infrared ray communicating unit(S100). A controller of the mobile terminal requests standard information of an address list from the other mobile terminal(S110). When the mobile terminal receives the address list standard information from the other mobile terminal(S120), the controller analyzes the received address list standard and displays a corresponding result through a user interface unit(S130). The controller checks whether address data is to be transmitted to the other mobile terminal by detecting an input of the user interface(S140). If the address data is to be transmitted to the other mobile terminal, the controller selects target address data to be transmitted to the other mobile terminal(S150). The controller converts the address data into the same standard as the address list of the other mobile terminal(S160) and then transmits it to the other mobile terminal(S170).
