Method for identifying a mobile telephone

1. A method for identifying a mobile device, where there is an ADD system (Automatic Device Detection) connected to a network for mobile communication, the ADD system comprising a TCD (Terminal Capabilities Database) with SAT (SIM Application Toolkit) terminal profile values stored for all device models, the method comprising:

retrieving an IMEI (International Mobile Equipment Identity) number from the device,

retrieving the device model and the SAT terminal profile (P 2 ) from the TCD by means of the retrieved IMEI,

obtaining the SAT terminal profile (P 1 ) of the device from the device,

comparing the SAT terminal profile (P 1 ) obtained from the device with the SAT terminal profile (P 2 ) obtained from the TCD in the ADD system, and

considering the device as having an unmanipulated IMEI number in a case that the SAT terminal profile (P 1 ) obtained from the device and the SAT terminal profile (P 2 ) obtained from the TCD coincide.

2. The method according to claim 1 , wherein the SAT terminal profile (P 1 ) of the device is obtained by means of a SIM card reading the SAT terminal profile (P 1 ) of the device.

3. The method according to claim 1 , wherein a MSISDN (Mobile Station ISDN Number) and the IMEI are obtained from a network probe and are transferred to the ADD system.

4. The method according to claim 1 , wherein a MSISDN (Mobile Station ISDN Number) and the IMEI are obtained by means of a SIM card in the device.

5. The method according to claim 1 , further comprising:

a) the ADD system picking up a MSISDN (Mobile Station ISDN Number) and the IMEI from said network,

b) the ADD system querying said TCD for the model of the device using the IMEI number as input,

c) the TCD transferring information regarding the model to the ADD system,

d) the ADD system querying the device, via its SIM card, for the SAT terminal profile (P 1 ) and the SAT terminal profile (P 1 ) is transferred to the ADD system,

e) the ADD system querying the TCD for the SAT terminal profile (P 2 ) for said model and the SAT terminal profile (P 2 ) is transferred to the ADD system, and

f) the ADD system comparing the two SAT terminal profiles (P 1 , P 2 ) to determine if they match or not.

6. The method according to claim 1 , further comprising:

a) a device detection system detecting that a subscriber has a new device,

b) the device detection system transferring information that the new device has been found to the ADD system,

c) the ADD system picking up a MSISDN (Mobile Station ISDN Number) and an IMEI and the SAT terminal profile (P 1 ) from a SIM card of the new device,

d) the ADD system querying said TCD for the model of the new device using the IMEI number as input,

e) TCD transferring information regarding the model to the ADD system,

f) the ADD system querying the TCD for the SAT terminal profile (P 2 ) for said model and the SAT terminal profile (P 2 ) is transferred to the ADD system, and

g) the ADD system comparing the two SAT terminal profiles (P 1 , P 2 ) to determine if they match or not.

7. The method according to claim 2 , wherein a MSISDN (Mobile Station ISDN Number) and the IMEI are obtained from a network probe and are transferred to the ADD system.

8. The method according to claim 2 , wherein a MSISDN (Mobile Station ISDN Number) and the IMEI are obtained by means of the SIM card in the device.

9. The method according to claim 1 , wherein the SAT terminal profile (P 1 ) is not unique for each device models of all the device models.

10. The method according to claim 1 , further comprising considering the device as having a manipulated IMEI number in a case that the SAT terminal profile (P 1 ) obtained from the device and the SAT terminal profile (P 2 ) obtained from the TCD do not coincide.

11. The method according to claim 10 , further comprising, restricting service settings to the device in the case the device is considered to have the a manipulated IMEI number.

12. The method according to claim 4 , further comprising:

a) a device detection system detecting that a subscriber has a new device, and

b) the device detection system transferring information that the new device has been found to the ADD system.

13. The method according to claim 12 , further comprising in the case that the device is considered to have a manipulated IMEI number, sending off a switch event notice to the ADD system, the switch event notice including MSISDN, IMEI, and SAT terminal profile of the device.

14. A method for identifying a mobile device, where there is an ADD system (Automatic Device Detection) connected to a network for mobile communication, the method comprising:

storing a SAT (SIM Application Toolkit) terminal profile on a TCD (Terminal Capabilities Database) for each device model that communicates within the network;

retrieving an IMEI (International Mobile Equipment Identity) number from the device,

retrieving the device model and the SAT terminal profile (P 2 ) from the TCD based on the retrieved IMEI,

obtaining the SAT terminal profile (P 1 ) of the device directly from the device,

comparing the SAT terminal profile (P 1 ) obtained directly from the device with the SAT terminal profile (P 2 ) obtained from the TCD, and

considering the device as having an unmanipulated IMEI number in a case that the SAT terminal profile (P 1 ) obtained from the device and the SAT terminal profile (P 2 ) obtained from the TCD coincide.

15. The method according to claim 14 , further comprising considering the device as having a manipulated IMEI number in a case that the SAT terminal profile (P 1 ) obtained from the device and the SAT terminal profile (P 2 ) obtained from the TCD do not coincide.
