SESSION MANAGEMENT APPARATUS, COMMUNICATION SYSTEM, AND SESSION CLEAR-OUT METHOD

摘要

PROBLEM TO BE SOLVED: To suitably maintain a normal session and clear out a residual session in a radio communication system in which mobile terminals and fixed terminals are mixed.

SOLUTION: A session management means holds session information concerning sessions for the fixed terminals and sessions for the mobile terminals including type information indicating a terminal type and status information indicating a status of communication. A session clear-out means disconnects a session in which the type information indicates the mobile terminal and in which communication has not been performed for a time period longer than or equal to a first monitoring time period, on the basis of the session information held in the session management means.
