MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a mobile communication system including a mobile terminal, a base station which carries out radio communications with the mobile terminal, and an access management device which manages access from the mobile terminal to the base station, which, when an access group comprised of 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 to a base station included in the same access group. When a predetermined condition is satisfied after a mobile terminal subscribes to the access group in such a way that the mobile terminal is granted permission to temporarily access to 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 same access group. As a result, the processing load imposed on the network side can be reduced, and needless use of radio resources can be prevented.
