摘要：
Increased network security is provided by monitoring (in 28) in real time one or more characteristics or attributes of telephone calls that are placed through the network (10) and notifying the network customer, (at 38, 42 or 44), in real time, when the attributes are indicative of abnormal or fraudulent network usage. The subscriber, once notified of the abnormal usage, is in a position to take steps to minimize unauthorized network usage. For example, the subscriber can selectively block network usage, deny access to the network on a call-by-call basis, or trace the call to catch the unauthorized user while the call is still in progress.
