Abstract
When a network is in a state of requiring some sort of access barring, a reference value notified to a mobile device is determined to indicate a value in which an access of a certain mobile device is denied while an access of another mobile device is allowed. When an own device has a special type access class, it is determined that an access is allowed The appropriateness of an access is determined according to designation from the network when the own device has the special type access class, and when the own device does not have the special type access class, it is determined that an access is denied.
