Abstract
Method for identifying a mobile telephone, a device, where there is a ADD system (1) (Automatic Device Detection) system connected to a network (2) for mobile communication, the ADD system including a TCD (3) (Terminal Capabilities Database) with SAT (SIM Application Toolkit) terminal profile values stored for all device (4) models. The method includes the steps of retrieving the IMEI (International Mobile Equipment Identity) number from the device (4), retrieving the device model and the SAT terminal profile (P2) from the TCD by way of the retrieved IMEI, obtaining the SAT terminal profile (P1) of the actual device, comparing the SAT terminal profile (P1) of the actual device with the SAT terminal profile (P2) obtained from the TCD in the ADD system, and considering the device as having the right IMEI number when the SAT terminal profile of the actual device and the SAT terminal profile obtained from the TCD coincide.
