<p>A wireless communications network between mobile user equipment and a core network includes multiple nodes base stations (BTS, nodeB), controllers (BSC) and gateways (GGSN, SGSN). Each of these may include an application which monitors data/traffic from the mobile terminals to determine if any are malfunctioning. The malfunction may be due to a fault, virus/malware infection or other reason. The monitor compares mobile terminal behaviour with thresholds for correct and erroneous operation A,B,C,D and if it is determined F that the device is misbehaving a management event (eg. blocking/limiting network traffic access) is triggered H. The normal/erroneous operation thresholds may be based on historical records G or uploaded signatures. The thresholds may be specific to a device, a device family or a particular application running on a device.</p> |
