METHOD AND A SYSTEM FOR PROVIDING AN INFORMATION VISUALIZING SERVICE THROUGH DATA TRANSMISSION DURING A CALL ATTEMPT IN A MOBILE COMMUNICATION NETWORK, PARTICULARLY FOR TRANSMITTING PRE-SET DATA TO A CALLEE TERMINAL SO AS TO BE DISPLAYED AT THE CALLEE TERMINAL WHEN A CALLER ATTEMPTS A CALL

摘要

PURPOSE: A method and system for providing an information visualizing service through data transmission during a call attempt in a mobile communication network are provided to allow a callee terminal to receive data through a channel under a call attempt without occupying a channel additionally, and save a communication usage charge. CONSTITUTION: A data transmission server(230) allows a caller terminal(210) and/or a callee terminal(212) to select transmission data to be transmitted while a call is being attempted by proposing a list of a plurality of transmission data, and when the caller terminal(210) requests a call, the data transmission server(230) transmits the selected transmission data to the caller terminal(210) while the call is being attempted to the callee terminal(212). The caller terminal(210) and the callee terminal(212) select/set transmission data to be transmitted during the call attempt, display the transmission data received from the data transmission server(230) on a screen, and wirelessly communicate with each other when a speech path is set. A data transmission database(232) stores the plurality of data to be transmitted during the call attempt.
