PURPOSE: A terminal providing message transmission-receiving function during call, a service system and a control method thereof are provided to check a message received without additional operation and to transmit a message to a desired opponent during the call. CONSTITUTION: If call connection is requested from a first terminal, a call control system (210) performs control operation to connect the call to a second terminal corresponding to a received number. A media system (230) provides call service under the state that the call is connected. A message system (220) receives message sending request from the first terminal while the media system provides the call service. The message system processes the message. The message is provided in the same channel as the call.
