A system and method for proactively detecting cloning fraud in a cellular mobile telephone environment are discussed. Information is collected which corresponds to registration notifications of the cellular telephones as they operate within the cellular mobile telephone environment. The registration information is used to detect time-space peculiarities. Specifically, registrations having the same mobile identification number and occurring in different mobile switching centers within a predetermined time interval are identified. This time interval, based on a reasonable travel time between cells covered by the different mobile switching centers where the registrations originated, is used as a threshold for detecting cloning fraud.

System and method for detecting cloning fraud in cellular/PCS communications

To provide a complete picture of the calling pattern of calls placed to a destination entity which permits the destination entity's routing plan to be adequately administered, a) information is collected about all call attempts to particular, specified dialed numbers even before they are switch routed, including even calls terminated before a network control point (NCP) returns instructions as to where to route the call and, if applicable, after they are rerouted and b) the collected information is periodically delivering as it becomes available, for use by the destination entity, without requiring the calls being monitored to have been terminated. Thus, for example, information is collected about calls being held by the NCP in a queue even before the calls are NCP routed. The collected information also includes information for calls that were never routed, because they were terminated before routing, independent of whether they were placed in a queue. If applicable, additional information is collected about the rerouting of those calls that are rerouted. Additionally, information is collected concerning the performance of a network control point, including information on queue performance and routing location selection performance.
