Abstract

This online system has multiple terminals connected with a host computer through communication lines. The host computer includes an online information processing means for processing information by executing an online program, a session control means for setting/disconnecting processing of the session with the above multiple terminals, and a session control information table for storing information needed for setting/disconnecting the session. The session control information table has an information area to store the logical address of the other terminal and information to indicate the session state with the applicable other terminal. The session control means, based on the message of session setting/disconnecting request sent from the online information processing means or terminal, sets/disconnects the session with reference to the information area of the session control information table. It also stores the state of the logical address and session of the other terminal contained in the message at the time of setting/disconnecting of the session, into the information area of the session control information table.
