SYSTEM AND METHOD FOR CONTROLLING REGISTRATION ON A MOBILE TELECOMMUNICATIONS NETWORK

摘要

Subscriber equipment for use in a mobile telecommunications network, said subscriber equipment comprising: storage means for storing forbidden network identity data identifying at least one identity of a forbidden network and allowed network identity data identifying at least one identity of an allowed network; a processor for: comparing data indicative of an identifier of a network with said allowed network identity data; updating said forbidden network identity data with said identifier of a network in response to said comparing indicating that said network is not identified as an allowed network, thereby providing a way of inhibiting registration onto an undesirable network. Thus, subscriber equipment associated with a user A in a first country 1 may be inhibited from roaming onto a network 2 in a second country 2.
