Abstract

This disclosure relates to billing fraud detection. An example relates to a billing system for subscribers in a telecommunications network. Billing fraud can be detected by implementing a mechanism for performing integrity verification on parameters of a charge receipt (CDR), including subscriber and device identifiers, which may include GPSI, IMEI, IMSI, cell ID, location information, etc. Any parameter that has been determined to be invalid can be modified. Modification can represent one or more of the following examples: changing the value of the parameter; marking the parameter as invalid; or marking the CDR as invalid. Reports related to parameters (or CDRs) deemed invalid (or valid) can be executed. Multiple network functions of the core network of the telecommunications network interact to perform integrity verification and take action or report the results of the integrity verification.
