A method of identifying fraud in a telecommunications system. The method includes receiving data related to a current call placed from an originating automatic number indicator (ANI), where the received data includes at least the originating ANI, a billing number and an identification code. A threshold number and a time interval corresponding to the identification code for the originating ANI are retrieved, for example, from a memory. In addition, billing numbers for prior calls from the originating ANI, if any, and corresponding indicia of the times of the calls are retrieved. A determination is made of whether the number of billing numbers used for the current and prior calls from the originating ANI over a prior period of time equal to or less than the time interval exceeds the threshold number. If the threshold number is exceeded, a fraud alert is generated. |

DETAILED DESCRIPTION It is an objective of the present invention to provide a method and system for detecting fraudulent calls made from an originating ANI.
It is an objective of the present invention to have such detection take place through up-front processing.
It is also an objective of the present invention to prevent further fraudulent calls from being made at the originating ANI.
In accordance with these objectives, one preferred embodiment of the present invention provides a method of identifying fraud in a telecommunications system.
The method includes receiving data related to a current call placed from an originating ANI, where the received data includes the originating ANI, a billing number and an identification code.
A threshold number and a time interval corresponding to the identification code for the originating ANI are retrieved, for example, from a memory.
In addition, billing numbers for prior calls from the originating ANI, if any, and corresponding indicia of the times of the calls are retrieved.
A determination is made of whether the number of billing numbers used for the current and prior calls from the originating ANI over a prior period of time equal to or less than the time interval exceeds the threshold number.
If the threshold number is exceeded, a fraud alert is generated.
Another preferred embodiment of the invention is also a method of identifying fraud in a telecommunications system.
The method includes receiving data related to a current call placed from an originating ANI, where the received data includes the originating ANI, a billing number and an identification code.
The received data for the originating ANI is stored, for example, in a memory.
The billing numbers and corresponding indicia of times of calls from the originating ANI and the identification code for the originating ANI are retrieved at an initiating event.
(The initiating event may be the receipt of data related to the current call placed from the originating ANI, or the elapse of a period of time
