The mobile terminal with anti-theft function and the anti-theft method for the mobile terminal provided by the present invention can initiate a positioning service request and report the current location of the mobile phone when the mobile phone is stolen or lost, so that the legal owner of the mobile phone can quickly obtain the location of the mobile phone , and then retrieve the phone. In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Please refer to FIG. 1 , which is a block diagram of a mobile terminal with an anti-theft function according to the present invention.

Mobile phone anti-theft device of the present invention comprises:

The anti-theft module 101 is used to judge whether the mobile phone is illegally used after being stolen or left behind, and if so, sends an anti-theft positioning service request to the positioning module 102;

The positioning module 102 is used to communicate with the positioning server according to a certain process after receiving the anti-theft positioning service request from the anti-theft module, obtain the current location information of the mobile phone, and deliver the processed location information to the alarm module 103;

The alarm module 103 is used to send the current location of the mobile phone obtained by the positioning module to the alarm number;

Restoration module 104, is used for judging whether this mobile phone legitimate owner obtains mobile phone again, if yes then further restore mobile phone normal use;

The storage module 105 is used for storing the information used by the anti-theft module, the positioning module, the alarm module and the recovery module.

When the mobile phone is turned on, the anti-theft module 101 automatically reads the identification code SI of the current SIM card, such as the International Mobile Subscriber Identity (IMSI), and compares it with the legal SIM card identification code stored on the mobile phone. Wherein, the identification code stored on the mobile phone is the identification code of the SIM card put in when the mobile phone works normally. If the identification code of the current SIM card is different from the SIM card identification code stored on the mobile phone, the anti-theft module will require the user to input the correct SIM card replacement password PW1 within a limited number of times or time. If the user fails to input the correct SIM card replacement password PW1 within the limited number of times or time, the anti-theft module thinks that the mobile phone is being used illegally, and sends an anti-theft positioning service request to the positioning module. The limited number of times or limited time mentioned here is set by the legal owner of the mobile phone. For example, the limited number of times can be 1 time, 3 times, etc., and the limited time can be 10 seconds, 1 minute or 5 minutes.

After the positioning module 102 receives the anti-theft positioning service request proposed by the anti-theft module 101, it initiates a positioning process according to the provisions for "SET Initiated" in the Open Mobile Alliance (Open Mobile Alliance, OMA) location business service standard SUPL. The positioning module establishes an Internet protocol (Internet Protocol, IP) connection with the SLP through the SUPL Agent in the mobile phone, sends a SUPL START message, and starts the positioning process. At the end of the positioning process, the positioning module receives a SUPL END message containing location information from the SUPL Location Platform (SLP). If the legal owner of the mobile phone sets the anti-theft positioning service repetition period TIME1, the positioning module initiates a positioning process every this period. After each location process receives the SUPL END message, the processed location information is handed over to the alarm module 103 for subsequent processing.

The alarm module 103 sends the location information obtained by the positioning module 102 to the alarm number NUM set by the legal owner of the mobile phone by means of a phone call or a short message (Short Message Service, SMS) or a multimedia message (Multimedia Messaging Service, MMS). The alarm number can be one or more of the number of the legal owner of the mobile phone, other numbers trusted by the legal owner of the mobile phone, the acceptance number of the system operator, or the acceptance number of the public security organ. The legal owner of the mobile phone can also set the priority of the above-mentioned numbers, and then contact the number with a lower priority when the number with a higher priority cannot be contacted. If the legal owner of the mobile phone has set the anti-theft positioning service repetition period TIME2, the alarm module will send the mobile phone location information to the alarm number every this period.

The recovery module 104 is used for judging whether the legitimate owner of the mobile phone has found the stolen mobile phone. If the current user can input the correct password PW2 for removing the stolen state, then the recovery module thinks that the current user is the legal owner of the mobile phone, thereby removing the stolen state and recovering the normal use of the mobile phone.

The storage module 105 is used to store the legal SIM identification code SI and the replacement SIM card password PW1 for the anti-theft module 101 to compare, the period control information TIME1 for the positioning module 102, the alarm number NUM and the period control information TIME2 for the alarm module 103 to use, The unstolen state password PW2 for use by the recovery module 104 .

Please refer to FIG. 2 . FIG. 2 is a flow chart of the mobile terminal anti-theft method of the present invention.

Step 201, when starting up, automatically read the identification code SI of the current SIM card. The identification code can be the International Mobile Subscriber Identity IMSI, or other identification codes that can uniquely identify the SIM card.

Step 202, read the identification code of the legal SIM card stored in the mobile phone. A legal SIM card refers to the SIM card placed in the mobile phone during normal use.

Step 203, comparing the identification code of the current SIM card and the identification code of the legal SIM card stored in the mobile phone at the time of starting up this time. If the two identification codes are the same, go to step 212; otherwise, go to step 204.

In step 204, the user is required to input the SIM card replacement password within a limited time or limited times. If the user input is correct, execute step 211; otherwise, execute step 205. Wherein the limited number of times or the limited time is set by the legal owner of the mobile phone, for example, the limited number of times can be 1 time, 3 times, etc., and the limited time can be 10 seconds, 1 minute or 5 minutes, etc.

In step 205, the anti-theft module determines that the mobile phone is currently stolen or illegally used after being left behind, and requests the anti-theft positioning service to the positioning module.

Step 206, the positioning module initiates a positioning process according to the provisions of "SET Initiated" in the OMA location service service standard SUPL. The positioning module establishes an IP connection with the SLP through the SUPLAgent in the mobile phone, sends a SUPL START message, and starts the positioning process.

Step 207, at the end of the positioning process, the positioning module receives a SUPL END message containing position information from the SLP.

In step 208, the alarm module sends the location information of the mobile phone processed by the positioning module to the alarm number set by the legal owner of the mobile phone through call, SMS, MMS and other means. The alarm number can be one or more of the number of the legal owner of the mobile phone, other numbers trusted by the legal owner of the mobile phone, the number accepted by the system operator, or the number accepted by the public security organ. The legal owner of the mobile phone can also set the priority of the above-mentioned numbers, and then contact the number with a lower priority when the number with a higher priority cannot be contacted.

Step 209, the recovery module judges whether the legal user of the mobile phone has retrieved the mobile phone according to whether the correct password for releasing the stolen state has been input. If so, execute step 211 to resume the normal operation of the mobile phone; otherwise, consider that the mobile phone is still in a stolen state, and execute step 210.

Step 210, according to the time interval set by the legal user of the mobile phone, periodically send the anti-theft positioning service request, and send the current location information of the mobile phone to the alarm number after each positioning process, so as to dynamically locate the stolen mobile phone.

Except for asking the user to enter a password, all the above steps are completed when the mobile phone screen is displayed normally. In this way, the tracking of the mobile phone can be completed without the illegal user of the mobile phone knowing.

For steps 201 to 205 in the accompanying drawing 2, what this embodiment adopts is to judge whether the mobile phone is stolen according to whether the SIM card replacement is legal. However, the present invention is not limited to using this method to judge that the mobile phone is stolen, and other methods can also be set by the legal owner of the mobile phone, such as stipulating that a preset password must be input every time the phone is turned on, or a preset password is periodically required to be input. password.

For step 206 in the accompanying drawing 2, the SUPL START message sent by the SUPL Agent includes not only the content specified by the SUPL standard, but also the identification code of the legal SIM card and the sign used to mark this positioning service as an anti-theft positioning service symbol. The purpose of adding the identification code of the legal SIM card is to facilitate the SLP to charge for the location service. The identifier used to mark this positioning service as an anti-theft positioning service is added to distinguish it from ordinary positioning service requests, so that SLP can prioritize processing this request; at the same time, for anti-theft positioning services, SLP can provide higher positioning accuracy; The SLP may also adopt different charging standards for the anti-theft location service and the common location service.

For steps 206 and 207 in the accompanying drawing 2, what this embodiment adopts is one of the mobile terminal positioning solutions, that is, the SUPL standard based on the assisted global positioning system (AssistedGlobal Positioning System, AGPS) developed by OMA. Yet the present invention is not limited to adopting this kind of solution (SUPL), for example also can adopt gpsOne; Also not limited to adopting this kind of positioning method (AGPS), for example also can adopt GPS, cell identification (Cell Identifier, CELLID), enhanced Enhanced Observed Time Difference (EOTD), Advanced Forward Link Trilateration (AFLT), Enhanced Forward Link Trilateration (EFLT), Time Of Arrival, TOA)/Time Difference Of Arrival (TDOA)/Observed Time Difference Of Arrival (Observed TDOA, OTDOA), Arrival Angle (AngleOf Arrival, AOA), Mobile Positioning System (Mobile Positioning System, MPS), Satellite Tool Kit (Satellite Tool Kit , STK), Global Navigation Satellite Systems (Global Navigation Satellite Systems, GNSS), Assisted Global Navigation Satellite System (Assisted GNSS, AGNSS) and other technologies.

For step 207 in FIG. 2 , the location information obtained in this embodiment is latitude and longitude information. However, the present invention is not limited to obtaining this type of information in this step, and the positioning application can also carry latitude and longitude information to its service provider (Service Provider, SP) to initiate a request for obtaining maps or detailed information. Information Systems, GIS), or the SP is connected to an external GIS system, and the longitude and latitude are converted to street information in the GIS, and then returned to the mobile phone by the SP.

In a word, the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
