Abstract
When voice communications are to be established using the telephone having the telephone number displayed on the application during the data communications, a temporary line disconnection unit disconnects a line being used for the data communications. The application is not notified of this, and the line is connected between the terminal and the telephone. The user on the mobile computer side can voice-communicate with the user of the telephone using the terminal. When the voice communications terminate, the temporary line disconnection unit connects the line between the fixed computer side and the mobile computer side to resume the data communications. Since the application is not notified of the temporary disconnection of the line, the session is set active and the data communications are not started from the very beginning.
