METHOD AND DEVICE FOR CONTROLLING ACCESS TO MOBILE TELECOMMUNICATIONS NETWORKS

摘要

To control access by any given mobile terminal to a mobile telecommunications network, a smartcard (i.e. a SIM) is arranged to include a list of device identifiers corresponding to one or more mobile terminals together with an indication of their respective access categories (i.e. black-list, grey-list or white-list). This list is constructed from an updated list of identifiers of mobile devices into which the smartcard has been inserted. This may be enhanced with a limited number of generic excluded identifiers. The smartcard thus maintains a local database of banned devices and/or devices that need to be monitored by the network.
