Methods for Composing Multimedia Message by Bidirectional Communication

PURPOSE: A method for writing an MMS(Multimedia Message) through bidirectional communication is provided to optionally select image data in list information randomly, and to include an outputted text message or music in a message, thereby dynamically writing the MMS. CONSTITUTION: A user accesses a mobile communication system(S101). The mobile communication system connects a terminal to a server computer(S102). List information newly updated in the server computer is displayed on a screen by a display module(S103). While a movement of an image selected through an output unit of the terminal is displayed, the user inputs a text message through a setup unit(S107). The user optionally selects volume of music sound through the setup unit(S108). The server computer generates an MMS, and temporarily outputs the MMS through the output unit of the terminal(S109). Colors of the text message and scroll speed are transmitted to the server computer(S110). The server computer requests to input a telephone number of a receiver, and transmits the written MMS through a communication provider system(S113).
