Detailed ways

The mobile terminal is now regarded as a mobile phone as an example, and the present invention is described in detail:

When the mobile phone is used for the first time or a valid SIM (Subscriber Identification Module) card is installed, browse the function menu of the mobile phone, the option of locking the SIM card or storing the phone number will appear on the screen, after confirmation, enter the password according to the prompt (this password can be used in other menus later) Change), after confirmation, the mobile phone will automatically save the current SIM card phone number of the mobile phone (this password is stored in the mobile phone). The optional mobile phone function menu includes an item to save the owner's fixed contact number and owner's name and specific contact address, and can modify the PIN code of the locked SIM card (this password is stored in the SIM card).

Referring to Figure 1, when starting up each time, the mobile phone will automatically compare whether the phone number of the current SIM card is consistent with the phone number of the legal SIM card stored in the mobile phone. The SIM card number has been changed, please enter the password and confirm the change." At this time, if the owner wants to use the SIM card instead, the correct password is input, and the mobile phone automatically compares the current password with the password stored in the mobile phone. If they are the same, the mobile phone starts up normally, and automatically updates the current SIM card phone number stored in the mobile phone. If the password is different, it will prompt "You have entered the wrong password, please re-enter". If the input is wrong three times, the mobile phone will also be turned on, and at the same time, words such as "the mobile phone is initializing, please wait..." will appear on the screen to confuse the thief. Record the mobile phone numbers of all the people and send the stolen short messages (note: most mobile phone users store mobile phone numbers in their mobile phones). The content of this short message can include the IMEI (International Mobile Equipment Identifier) number of the mobile phone itself, the SIM card phone number of the original mobile phone, the SIM card number of the current mobile phone thief, the information prompt that the original mobile phone has been lost, and the owner's contact number and Owner's name. In this way, as soon as the friends in the address book receive the short message, they can automatically know that the SIM card has been lost for the time being when the mobile phone is lost. Misunderstanding, and the personal situation of the current embezzler can be understood and tracked according to the information in the short message. After the short message is sent, the keys of the mobile phone will be locked automatically and the screen will display: "This is the prompt message of the stolen mobile phone and the contact number and address of the owner", prompting the person who has stolen the mobile phone to return the mobile phone automatically. If the mobile phone has a hands-free function, the mobile phone itself can also continuously send out the voice prompt "This is a lost mobile phone, please return it to the owner as soon as possible" through the loudspeaker. Like this, although can make the stolen person have this illegal mobile phone but without any practical use.

Referring to Figure 2, according to the GSM11.11 SIM card protocol standard in the international wireless communication protocol standard currently adopted by our country. It stipulates that the SIM card has a locking function. When the owner finds that the mobile phone is lost, he can also send a short message to his mobile phone in the first time. The short message can contain a custom format, including the original settings stored in the mobile phone SIM. Card's lock PIN code. When the mobile phone receives the short message, it will automatically compare it with the locking PIN code stored in the SIM card, and if they match, the SIM card will be locked, even if the SIM card is put into other mobile phones, it can no longer be used. And it can be displayed on the screen of the original mobile phone: "This is the prompt information of the stolen mobile phone and the contact number and address of the owner", prompting the owner of the mobile phone to return the mobile phone automatically. Only after restarting the machine and manually inputting the correct PIN code originally set and stored in the SIM card, the SIM card is allowed to be used normally. In this way, the owner can lock the SIM card as soon as he knows that the mobile phone is lost, and the illegal owner of the mobile phone cannot make a phone call, and the economic loss of the legal owner can be reduced to a minimum. If the mobile phone software forms a standard in this aspect in the future, no matter the SIM card is placed in any mobile phone, it can be locked in the same way.

Referring to Fig. 3, it is a flow chart of common mobile phone SIM card locking.

According to the GSM03.40 and GSM04.11 short message protocol standards in the international wireless communication protocol standards currently adopted by our country. It stipulates that short messages should be automatically stored for 12 hours in the short message center of the telecom operator, and automatically received when the user's mobile phone is turned on. Therefore, it can be guaranteed that the mobile phone receives the short message in the first time to realize the function of anti-theft calling of the mobile phone.

The mobile phone anti-theft and automatic alarm functions of the invention have high efficiency, strong reliability and easy software implementation.
