<p>To detect an anomaly of traffic emitted from at least one mobile terminal (TM) in a radiocommunication network, a device able to communicate with a location register (HLR) of the radiocommunication network (RR), comprises an evaluation module (ME) for incrementing, over a predetermined time interval, an authentication count (CA) assigned to the mobile terminal, when security data (DS) are transmitted to an entity of the network so as to authenticate the mobile terminal, so as to detect an anomaly of traffic emitted by the mobile terminal if the authentication count exceeds a predetermined threshold on the expiry of the predetermined time interval, and so as to transmit a message relating to this traffic anomaly to a network entity responsible for taking all useful measures for removing said anomaly.</p> |
