Below be the forced shutdown process that example further specifies mobile phone with the GSM network:
Based on the mobile phone of GSM network, its normal mobile phone power-on process in fact is mobile subscriber's a registration process.When the cellphone subscriber registers, a SIM card be must be inserted with in the mobile phone, user's registration information and personal authentication's key K I value in SIM card, comprised.When the cellphone subscriber registered, mobile phone sent IMSI to the base station, and (internationalmobile subscriber identity) after this IMSI is received in the base station, submits to HLR (home locationregister), and sent request prison power signaling to HLR.HLR generally can generate three random numbers (abbreviating RBASE as), and respectively three RBASE be carried out the A3A8 cryptographic calculation according to mobile telephone registration user's KI after receiving prison power signaling, and the result of computing is called BU.After finishing computing, HLR will pass to the base station under these 3 groups of RBASE-BU.Picked at random one group of data wherein in base station are used for this time prison power.The base station sends to mobile phone with the random number R BASE that chooses, and to the instruction of mobile phone request prison power.Mobile phone is by the KI value in the SIM card, use the cryptographic algorithm of A3A8, the random number R BASE that the base station is sent carries out computing, calculated result (being called MU) is returned MU and is sent to the base station, after the result of calculation MU of mobile phone transmission is received in the base station, the base station compares MU and BU, if MU is identical with BU, then succeed in registration, this process also is called prison power.After mobile phone receives that the correct prison power in base station is replied, then can start shooting (promptly this mobile phone is realized being communicated with network) comprehensively, but mobile phone enters talking state.Otherwise,, then represent registration failure if MU and BU are unequal, mobile phone receives that the prison power of base station mistake replys, and mobile phone is rejected networking, and mobile phone then can not be opened fully (though the power supply of mobile phone is opened, but mobile phone can't be realized being communicated with network), mobile phone can not enter normal talking state.
In the use:
At first card reader is arranged to " shutdown " order transmit status.When the cellphone subscriber holds mobile phone through this card reader 2, or operation on this card reader 2 on one's own initiative, be mobile phone card-brushing once, card reader 2 is with " shutdown " control information, pass through radiofrequency signal, be transmitted to mobile phone intelligent card 1 (can be described as the RF-SIM card), in this " shutdown " control information, comprise " invalid an enabling " variable (can be described as SIM-NE) is set to engineering noise, with a card reset signal, that is: the control mobile phone is started shooting again, finishes as top said user's registration and prison power process.
In the start process again of mobile phone, the mobile phone power-on prison temporary, the RF-SIM card reads the SIM-NE value that sets, because SIM-NE is set as engineering noise, by the KI value in the SIM card, use the cryptographic algorithm of A3A8, the random number R BASE that the base station is sent carries out computing, make calculated result (claiming MU) be invalid data or misdata, this invalid or wrong MU returns to the base station, and the base station just can not get correct prison power, therefore, this mobile phone just can't be realized being communicated with network, also just can not enter normal talking state.
At this moment, if user oneself forces start, also only be and automatically reset equally that because the SIM-NE in the RF-SIM card is an engineering noise, mobile phone also can't be realized start (promptly can't be communicated with the network realization).
When needs recover mobile phone with being communicated with of network the time, again card reader 2 is arranged to " start " order transmit status, allow the cellphone subscriber swipe the card once by this card reader 2 again, card reader 2 is with " start " control information, pass through radiofrequency signal, be transmitted to mobile phone intelligent card 1 (being the RF-SIM card), in this " start " control information, comprising " effectively an enabling " information is that the SIM-NE that blocks is set to " effectively ", with a card reset signal, that is: the control mobile phone is started shooting again, finishes as top said user's registration and prison power process.
Because the SIM-NE variable is " effectively ", when calculating MU, just no longer produce invalid data or misdata, but correct MU is returned to the base station, correct prison power is just realized in the base station like this, mobile phone just can obtain correct prison power and reply, and has just realized being communicated with between mobile phone and the network, and mobile phone just can normal talking.
This shows, in case mobile phone intelligent card 1 is configured to " invalid enabling ", it is inserted any one mobile phone, can't start shooting forever (promptly can't realize with network be communicated with) is till swipe the card on card reader 2, " effectively being enabled " activated again.
A kind of implement device that is used to force mobile phone shutdown of the present utility model has broad application prospects.
Such as being applied to middle and primary schools; allow student's mobile phone adopt RF-SIM card (being mobile phone intelligent card 1), place the card reader 2 that can mate use with the RF-SIM card at the doorway or the homeroom of school, the student went to school and last class hour; this card reader is set to " shutdown " order transmit status; the student swipes the card on card reader 2, like this to the school or when entering the classroom; " shutdown " instruction; just be sent to student's mobile phone by swiping the card, student's mobile phone has shut down with regard to compulsory.The student is in the activity and the learning time of school, and note can't be conversed and send to mobile phone just, and mobile phone can not normally use.When classes are over, school was set to " start " to card reader 2, when the student leaves school, swiped the card on card reader 2 again, and mobile phone has just been finished normal boot-strap, and student's mobile phone can normally use again.So just can satisfy the student and the head of a family and require to use mobile phone, also not influence the hope of study.
For another example, be used in the places such as meeting or library, user's mobile phone adopts RF-SIM card (being mobile phone intelligent card 1), and placing one on the doorway in meeting room or library can mate the card reader of using 2 with the RF-SIM card, this card reader is set to " shutdown " order transmit status, when the personnel that hold above-mentioned mobile phone enter, on card reader 2, swipe the card, like this, " shutdown " instruction, just be sent to above-noted persons' mobile phone by swiping the card, above-noted persons' mobile phone has shut down with regard to compulsory.Above-noted persons are in session or library, and note can't be conversed and send to mobile phone just, and mobile phone can not normally use.Meeting adjourned or when going out the library, card reader 2 is set to " start ", and above-noted persons leave the meeting room or during the library, swipe the card on card reader 2 again, and mobile phone has just been finished normal boot-strap, and above-noted persons' mobile phone can normally use again.
The foregoing description only is used for further specifying a kind of implement device of forcing mobile phone shutdown of the present utility model; but the utility model is not limited to embodiment; every foundation technical spirit of the present utility model all falls in the protection range of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
