The purpose of the present invention, ▲ · Description and other purposes, features, and advantages of the diagram are clearer and clearer for those skilled in the art through the following formula: .

[Detailed description of the invention First, if I refer to FIG. 1, the mobile phone is turned on (step 11

Page 5 573427 5. Description of the invention (3)), and then start the mobile phone (step 12), the mobile phone is in a standby state (step 13). After that, press the key to enter the phone menu (step 14) ^ At this time, select

Select "Lock SIM Card and Mobile Phone" that appears in the menu (step 15). After entering, there are several functions to choose from, for example, activating or stopping the lock of SIM card and mobile phone, setting the lock of SIM card and mobile phone code, and setting the password of unlocking mobile phone. If you choose to activate or deactivate the SIM card and mobile phone at this stage, there are two options to choose from, namely to activate or deactivate the "Enable SIM card and mobile phone lock" function (step 151); if you select "Enable", That is to set the lock SIM card and mobile phone function flag to l (LockFlag = l) (step 152) * At this time, as long as the following steps to lock the SIM card and mobile phone to achieve the lock Purpose, after that, the mobile phone will enter the standby state (step 154). However, if you select "Stop", you are setting the SIM card and mobile phone flag to 0 (LockFlag = 0) (Step 153). At this time, the "Lock" function has no effect, even if you receive the message Password, the mobile phone will not be locked. After that, the mobile phone enters the standby state (step 丨 55). If you choose to lock the SIM card and mobile phone, you can set the password (step 15 6), but the password can only be up to 160 ASCII characters according to the SMS protocol (for example, "Block my SIM" or " Lock SIM "),

After the setting is completed, the phone will automatically enter the standby state (step 157). If you choose to set the password for unlocking the mobile phone, you can set the password for unlocking the mobile phone (step 158). The password can be 8 digits (for example, "12345678", etc.). After that, the mobile phone is on standby. Secondly, please refer to Figure 2. Figure 2 shows locked SIM card and action

Page 6 573427 V. Description of the invention (4) Phone flow. After completing the password setting process described above, to lock the SIM card and mobile phone, follow the steps below. At the beginning, in the standby state (step 21), after receiving a short message (SMS) (step 22), the mobile phone will check whether the lock SIM card and mobile phone function flag (LockFlag) are 1 (step 23), if it is 1, it means that the function of locking SIM card and phone is activated; if the flag is 0, it means that the function of locking SIM card and phone is not activated, the locking action cannot be performed at all, and the short message is directly stored (step 2 3 1) After sending a general message to the user (step 232), the user enters the standby state (step 233). If the flag & j,

The mobile phone will determine whether the short message is the password to lock the SIM card and the mobile phone (step 24). If the short message is just a general short message, then directly store this = message (step 2 31) and send a general message to the user to alert the user (^ step 232) to a standby state (step 233). However, if the SMS = 疋 lock the SIM card and mobile phone password, the phone will start the piN code lock step 25), and then the phone automatically enters the wrong pIN code three times to lock the gw (step 26), and then proceed to _ The mobile phone is locked (step 27) and the mobile phone screen is locked (step 28).

After that, please refer to Figure 3. Figure 3 shows the operation process of unlocking the mobile phone with a password. First lock the mobile phone screen (step Luo i i enter the password to unlock the mobile phone (step 32), mobile phone = whether the fee code is broken (step 33), if the disk is not correct, the phone will still return

Li: Talk screen (step 331). If the password is broken, the phone will check if it is locked (step 34). If it is not locked, you can turn on the phone (step 34 丨) and it will be in standby mode (step 34 2); if the SIM card is locked

573427 V. Description of the invention (5) If you stay, the phone will ask for the PUK code (PIN UNLOCK KEY) (step 35). After the PUK code is entered, the phone will check whether the pUK code is correct (step 36). If it is correct, the phone will start ( Step 361), and then enter the standby state; if the PUK code is entered incorrectly, the mobile phone will check whether the SIM card is locked (Dead). If the SIM card is locked, the phone will enter the restricted dial emergency state (step 38) and become a restricted dial emergency state (step 39); if the SIM card is not locked, then

I Return to step 35. The mobile phone asks for the PK code. After entering the PUK code, the mobile phone will continue the following procedures until the correct PUK code is entered. The logic concepts and matching circuits used in the above methods are easily understood and implemented by those skilled in the art, and are not the focus of the present invention, so they will not be repeated here. Based on the above methods, the following situations can be adopted in the implementation of the present invention. In a mobile phone containing the present invention, the user activates the function of locking the SIM card and mobile phone in advance, and sets the short message to "Block my SIM" (for example), and the password to unlock the mobile phone is " 1 2345678 ', (For example), if the user finds that the mobile phone is lost, he can immediately ask a friend, colleague, or someone around him to send a short message password "Block my SIM" to his lost mobile phone. After receiving the SMS password, the lost mobile phone locks the SIM card and mobile phone. If the user retrieves the lost mobile phone, he can use the password "12345678" to unlock the mobile phone, and use the SIM unlock code (ρυκ) to unlock the SIM card. The SMS protocol in the GSM standard is usually used to transmit short messages. Generally, mobile phones are only responsible for displaying short messages on the screen. The short message is not analyzed. 573427 5. Description of the invention The short message content is compared with the stored short message password command to lock the SIM card and mobile phone, which not only saves time and time, but also prevents other people from making phone calls in a timely manner. No invention with the same purpose was found on the telephone. Therefore, the present invention does have industrial applicability, novelty, and progress, so it is necessary to file an application for an invention patent. However, the above is only one preferred embodiment of the present invention, and is not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes and modifications of the shape, structure, characteristics and spirit described in the scope of patent application of the present invention shall be included in the scope of patent application of the present invention.
