PURPOSE: A real-time data conversion and multi call access system using a mobile communication terminal is provided to transceive text data and a voice with the other party's terminal as maintaining a call access state during a voice call between mobile terminals, thereby enabling a subscriber to use the system when the voice call is suddenly unavailable. CONSTITUTION: Many mobile communication terminals(A1-An) transceive voice data and text data through a network assigned by a call setup with the other party's terminal. A mobile communication exchange(MCEX) relays transceiving of the voice data and the text data between the mobile communication terminals(A1-An). A data conversion/multi call access server(DEX/MCS) is connected to the mobile communication exchange(MCEX) in order to be accessible from the mobile communication terminals(A1-An), transceives the text data through the same call as maintaining a call access state of voice communication between the specific mobile communication terminals(A1-An), and enables a new call setup for accessing a specific server and a terminal as maintaining the call access state of the voice communication. |
