A method of entering and modifying user data of a mobile communication terminal
in a physically remote manner is provided A call is made from a mobile communication
terminal to a computer or from a computer to a mobile communication terminal. Here,
if a typical voice call or a simple data service call is connected, necessary data
cannot be entered into the right memory area of the mobile communication terminal
where said data have to be stored. In the present invention, a separate remote
data update mode is set up and data and commands for transmission and entry of
data are transmitted and received in this mode. According to the present invention,
such data which cannot be entered by users in a direct manner to a mobile communication
terminal as animation data or image data which are used for display on mobile communication
terminal screen, melody data which are used for a ring tone for mobile communication
terminal, game programs which are useable in mobile communication terminal, etc.,
can possibly be entered in addition to personal information data such as speed
dial numbers since users can manipulate a data manager program already installed
in the computer and thereby enter data to a mobile communication terminal and further
modify them.
