Abstract

An apparatus and method control booting in a mobile device with a built-in communication module to prevent a service user from using the mobile device for other purposes and to prevent the service user from subscribing to another service provider. A method includes determining, during a booting operation, whether the communication module is mounted with a USIM. A forced booting termination message is displayed if the communication module is not mounted with the USIM. And power supply is interrupted after a predetermined time from displaying the forced booting termination message.

Claims

1. A method for controlling booting in a mobile device with a built-in communication module, the method comprising:

determining, during a booting operation, whether the communication module is mounted with a universal subscriber identity module (USIM);

displaying a forced booting termination message in response to determining the communication module is not mounted with the USIM; and

interrupting a power supply after a predetermined time from displaying the forced booting termination message.

2. The method of claim 1, further comprising:

completing the booting operation and driving the corresponding operating program normally, in response to determining the communication module is mounted with the USIM.

3. The method of claim 1, wherein the communication module is a high speed packet access (HSPA) module.

4. The method of claim 1, wherein determining whether the communication module is mounted with a USIM comprises:

transmitting an attention (AT) command from a processor to the communication module; and

transmitting a response from the communication module to the processor in response to the AT command.

5. The method of claim 1, wherein determining whether the communication module is mounted with the USIM is performed during a Power-On Self Test.

6. A method for controlling booting in a mobile device, the method comprising:

determining, during a booting operation, whether the mobile device is mounted with a communication module and a universal subscriber identity module (USIM);

displaying a forced booting termination message in response to determining the mobile device is not mounted with the communication module and the USIM; and

interrupting a power supply after a predetermined time from displaying the forced booting termination message.

7. The method of claim 6, further comprising:

completing the booting operation and driving the corresponding operating program normally, in response to determining the mobile device is mounted with the communication module and the USIM.

8. The method of claim 7, wherein the communication module is a high speed packet access (HSPA) module.

9. The method of claim 7, wherein determining whether the mobile device is mounted with a communication module and a USIM comprises:

transmitting an attention (AT) command from a processor to the communication module and the USIM; and

transmitting a response from the communication module and the USIM to the processor in response to the AT command.

10. The method of claim 6, wherein determining whether the mobile device is mounted with the communication module and the USIM is performed during a Power-On Self Test.

11. An apparatus for controlling booting in a mobile device with a built-in communication module, the apparatus comprising:

a processor configured to determine, during a booting operation, whether the communication module is mounted with a universal subscriber identity module (USIM), display a forced booting termination message in response to determining the communication module is not mounted with the USIM, and interrupt a power supply after a predetermined time from the displaying of the forced booting termination message.

12. The apparatus of claim 11, wherein in response to determining the communication module is mounted with the USIM, the processor completes the booting operation and drives the corresponding operating program normally.

13. The apparatus of claim 11, wherein the communication module is a high speed packet access (HSPA) module.

14. The apparatus of claim 11, wherein the processor transmits an AT command to the communication module and receives a response from the communication module in response to the attention (AT) command, to determine whether the communication module is mounted with the USIM.

15. The apparatus of claim 11, wherein the processor determines whether the communication module is mounted with the USIM during a Power-On Self Test.

16. An apparatus for controlling booting in a mobile device, the apparatus comprising:

a processor configured to determine, during a booting operation, whether the mobile device is mounted with a communication module and a universal subscriber identity module (USIM), display a forced booting termination message in response to determining the mobile device is not mounted with the communication module and the USIM, and interrupt a power supply after a predetermined time from displaying the forced booting termination message.

17. The apparatus of claim 16, wherein in response to determining the mobile device is mounted with the communication module and the USIM, the processor completes the booting operation and drives the corresponding operating program normally.

18. The apparatus of claim 16, wherein the communication module is a high speed packet access (HSPA) module.

19. The apparatus of claim 16, wherein the processor transmits an attention (AT) command to the communication module and the USIM and receives a response from the communication module and the USIM in response to the AT command, to determine whether the mobile device is mounted with the communication module and the USIM.

20. The apparatus of claim 16, wherein the processor determines whether the mobile device is mounted with the communication module and the USIM during a Power-On Self Test.
