Abstract
An application () in a mobile network, receives an EIR trigger (MAP CHECK_IMEI). The application generates a signature derived from a device identifier (IMEI) and a subscriber identifier (e.g. IMSI), the signature not having a semantic meaning as it is pseudo-randomly generated. The application () checks if the signature exists in a signature store (); and if not, determines that the device/subscriber combination has not been detected in the network within a certain preceding time window, and stores the signature in the store, with an associated timestamp. It also transmits a notification to an external system such as a device management system. If the signature is already in the database, the application determines that the device/subscriber combination already exists in the network and updates a time stamp associated with the signature in the store to indicate the last time the signature was processed.
