Abstract

A method for controlling phone-locking of a mobile communication terminal which is capable of preventing a stranger from using freely a user'"'"'s terminal in case that the user'"'"'s terminal is lost in a state that a phone locking function of the terminal has not been set. The method for controlling phone-locking of a mobile communication terminal includes the steps of: receiving a phone-locking request signal form a user; transmitting an order message for phone-locking to a lost terminal, when the phone-locking request signal is received; and setting a phone-locked state for the lost terminal according to the transmitted order message for phone-locking.

Claims

1. A method for controlling phone-locking of a mobile communication terminal comprising the steps of:

receiving a phone-locking request signal form a user;

transmitting an order message for phone-locking to a lost terminal, when the phone-locking request signal is received; and

setting a phone-locked state for the lost terminal according to the transmitted order message for phone-locking.

2. The method according to

claim 1

, wherein the order message is transmitted from a mobile communication service provider through a base station to the lost terminal.

3. The method according to

claim 1

, wherein the step of transmitting an order message comprising the sub-steps of:

transmitting an order message to a lost terminal;

receiving a response signal to the order message from the lost terminal; and

transmitting an order message acknowledge signal to the lost terminal, when the response signal is received.

4. The method according to

claim 3

, wherein the order message is repeatedly transmitted for a predetermined number of times until a response signal is received.

5. The method according to

claim 1

, wherein the step of setting a phone-locked state comprising the sub-steps of:

receiving an order message from a base station;

checking whether the received order message is a message for phone-locking; and

reading a stored password, setting a phone-locked state and re-booting the terminal, in case that the received order message is a message for phone-locking.

6. The method according to

claim 5

, wherein the terminal executes a corresponding order command process in case that the received order message is a general order message.

7. The method according to

claim 5

, wherein the order message for phone-locking comprising:

a message type field;

an other protocol type field; and

an order specific field.

8. The method according to

claim 5

, wherein the terminal judges of the order message for phone-locking on the basis of the order specific field value of the order message.

9. The method according to

claim 5

, wherein in case that the user has not set a password for phone-locking or in case that a set password is ‘

0000’

, the terminal sets and stores the back four digits of the user'"'"'s phone number as a password to be used by the user for releasing phone-locking.

10. A method for controlling phone-locking of a mobile communication terminal including the steps of:

receiving an order message;

checking whether the received order message is a message for phone-locking;

reading a password from a memory in case that the order message is a message for phone-locking; and

enabling a variable value for phone-locking.

11. The method according to

claim 10

, wherein the order message is transmitted from a mobile communication service provider through a base station to the lost terminal.

12. The method according to

claim 10

, wherein the order message for phone-locking comprising:

a message type field;

an other protocol type field; and

an order specific field.

13. The method according to

claim 10

, wherein the terminal judges of the order message for phone-locking on the basis of the order specific field value of the order message.

14. The method according to

claim 10

, wherein in case that the user has not set a password for phone-locking or in case that a set password is ‘

0000’

, the terminal sets and stores the back four digits of the user'"'"'s phone number as a password to be used by the user for releasing phone-locking.

15. A method for controlling phone-locking of a mobile communication terminal comprising the steps of:

transmitting an order message to a lost terminal in case that a phone-locking request signal is received from a user; and

setting the state of the lost terminal as a phone-locked state according to the transmitted order message,

of which the step of setting a phone-locked state comprising the sub-step of;

receiving an order message;

checking whether the received order message is a message for phone-locking;

reading a password from a memory in case that the order message is a message for phone-locking; and

enabling a variable value for phone-locking.

16. The method according to

claim 15

, wherein the step of transmitting an order message comprising the steps of:

transmitting an order message to a lost terminal;

receiving a response signal to the order message from the lost terminal; and

transmitting an order message acknowledge signal to the lost terminal, when the response signal is received.

17. The method according to

claim 15

, wherein the order message for phone-locking comprising:

a message type field;

an other protocol type field; and

an order specific field.

18. The method according to

claim 15

, wherein the terminal recognizes the order message for phone-locking when the order specific field value of the order message is a predetermined value.

19. The method according to

claim 15

, wherein in case that the user has not set a password for phone-locking or in case that a set password is ‘

0000’

, the terminal sets and stores the back four digits of the user'"'"'s phone number as a password to be used by the user for releasing phone-locking.
