A mobile communication system including a mobile terminal, a base station carrying out radio communications with the mobile terminal, and an access management device managing access from the mobile terminal to the base station, which, when an access group including one or more mobile terminals and one or more base stations is registered with the access management device, grants a mobile terminal included in the access group permission to access a base station included in the access group. When a predetermined condition is satisfied after a mobile terminal subscribes to the access group and is granted permission to temporarily access the access group during an access permit period, and the access permit period expires, the mobile communication system excludes the mobile terminal for which the access permit period has expired from destinations to which a calling message is transmitted through a base station included in the access group.
