Abstract

Disclosed is a method for tracking a mobile communication terminal. The method includes configuring a mobile tracking feature; creating mobile tracking information when there is a difference between Subscriber Identity Module (SIM) card information stored in a SIM card currently being inserted into the mobile communication terminal and SIM card information stored in a memory after the mobile communication terminal is switched on, the mobile tracking information including current location information of the mobile communication terminal; and sending the mobile tracking information by generating a call to a pre-defined emergency call number.

Claims

1. A method for tracking a mobile communication terminal, the method comprising the steps of:

configuring a mobile tracking feature;

creating mobile tracking information when there is a difference between Subscriber Identity Module (SIM) card information stored in a SIM card currently being inserted into the mobile communication terminal and SIM card information stored in a memory after the mobile communication terminal is switched on, the mobile tracking information includes current location information of the mobile communication terminal; and

sending the mobile tracking information by generating a call to pre-defined emergency call numbers.

2. The method of claim 1, wherein each of the SIM card information includes International Mobile Subscriber Identity (IMSI) and Mobile Subscriber International Subscriber Number (MS ISDN).

3. The method of claim 2, wherein the mobile tracking information further includes the IMSI and the MS ISDN stored in the SIM card currently being inserted and subsequently the IMSI and the MS ISDN being stored in the memory.

4. The method of claim 3, wherein the step of configuring the mobile tracking feature comprises storing the emergency call numbers to the memory corresponding to a user selection of the emergency call numbers.

5. The method of claim 4, wherein the step of configuring the mobile tracking feature further comprises storing the IMSI and the MS ISDN stored in a SIM card being inserted into the mobile communication terminal when the emergency call numbers to the memory are stored.

6. The method of claim 4, wherein the step of configuring the mobile tracking feature further comprises storing the IMSI and the MS ISDN input by the user to the memory along with the emergency call numbers.

7. The method of claim 5, wherein the step of configuring the mobile tracking feature further comprises setting a password for providing password protection of the mobile tracking feature.

8. The method of claim 7, wherein the step of sending the mobile tracking information comprises creating user-user information Information Element (IE) containing the mobile tracking information, and including the user-user information IE into a call set up message.

9. The method of claim 8, wherein the step of sending the mobile tracking information comprises generating a call to the emergency call numbers using the call set up message.

10. The method of claim 9, wherein the method further comprises, when a call set up indication is received, extracting the mobile tracking information from the call set up indication and providing the mobile tracking information to the user.

11. The method of claim 10, wherein the mobile tracking information is a short message, the short message may be transmitted through a Short Message Service (SMS).
