<p>A basestation, for a cellular communication network, is described. The basestation is adapted to store a list of user equipments that are authorized to access the network by means of the basestation. In the event that the basestation receives a location update request from an unauthorized user equipment, the basestation is adapted to send a reject message to the unauthorized user equipment. The reject message specifically identifies the basestation, such that the unauthorized user equipment does not attempt to send any further location update request to the basestation.</p> |
