AN APPARATUS AND METHOD FOR CREDIT BASED MANAGEMENT OF TELECOMMUNICATION ACTIVITY |
摘要 |
The present invention provides an apparatus for credit based management of a telecommunication system. One embodiment of the apparatus includes an interface (133) for communicating credit information o n a particular subscriber and for receiving call records (113) for the particular subscriber that are derived from a switch (111) which est ablishes connections between telecommunication devices. A credit limit device (131) then utilizes the credit information to establish a credit limit for the subscriber. Another embodiment of the invention provides an apparatus for using a pre-call validation request that is associated with a subscriber of a telecommunication system who is attempting to place calls in an area serviced by another system (i.e. , roaming) to detect potentially fraudulent activity and , in particular, cloning fraud. In one embodiment, a detection device is provided that uses a time derived from the pre-call validation r equest to identify telecommunication activity that occurs in an improbable time seq uence and is therefore indicative of potentially fraudul ent telecommunication activity.
