Abstract
Information relating to previously made or received calls charged to a subscription associated with a given mobile station is stored in a data base. The information stored comprises called/calling party identification, time of day for the call, and duration of the call in relation to all long distance calls (incoming and outgoing) that are charged to the mobile station subscription. This information is then delivered at certain predetermined times to the subscriber via the mobile station. Responsive to receipt of the information, the subscriber may compare the cellular service record of prior subscription use to their own recollection of use. If the record and the recollection do not coincide, it is possible that a fraudulent use of the subscription via a cloned (or otherwise fraudulent) mobile station has occurred. A prompt report of the fraudulent use may then be made to the cellular service provider.
