Step S16: described mobile terminal generates SIM card recognition and verification sign according to the result that arranges of described authentication flag.
In the SIM card recognition methods of the embodiment of the present invention, mobile terminal and SIM card realize data transmission by the mode of less radio-frequency.
Particularly, the SIM card sequence number that in step S12, mobile terminal reads by wireless radio frequency mode in the SIM card that is independent of described mobile terminal comprises: SIM card is passive card, power supply signal in the radio frequency signal that this SIM card utilization receives generates the SIM card operating voltage, and each operational module in SIM card utilizes this SIM card operating voltage startup work; Also comprise the director data signal in the radio frequency signal that receives except comprising power supply signal, according to this director data signal, SIM card sends the SIM card sequence number of its storage in the mode of less radio-frequency.
In step S13, can adopt different cryptographic algorithm to utilize the SIM card sequence number to generate the encrypted authentication code.For example according to the SIM card sequence number,, in conjunction with the bound secret of user's input or in conjunction with the IMEI of terminal, generate the encrypted authentication code simultaneously.
Particularly, utilize wireless radio frequency mode that the encrypted authentication code is write in the program memory ROM of SIM card in step S14.
In step S15, SIM card, according to the described encrypted authentication code that receives, arranges the authentication flag by preset rules, and the authentication flag initial value that arranges in SIM card particularly is 0, and SIM card is after receiving the encrypted authentication code, and the authentication flag is set to 1.
Method described in step S11-S15 is that the operational order that receives is the SIM card recognition methods while swiping the card start-up command, by the method, SIM card and mobile terminal can be carried out man-to-man binding identification.
Particularly, after SIM card and mobile terminal binding, after mobile terminal-opening, mobile terminal sends the prompting instruction of swiping the card, and SIM card receives the described prompting instruction of swiping the card and produces supply voltage, activates SIM card work, and identify SIM card and swipe the card successfully this moment.
, if current SIM card is not close or do not sense SIM card in Preset Time, send the instruction of again swiping the card.
After wherein swiping the card successfully, the authentication of mobile terminal reading SIM card sign,, if the authentication flag that reads is 0, represent that current SIM card do not bind with current mobile terminal; , if the authentication flag that reads is 1, represent current SIM card and current mobile terminal binding.
When the authentication flag that reads was 1, current mobile terminal further read the SIM card information of access in SIM according to user's indication, and particularly, described SIM card information comprises userspersonal information and SIM network authentication information;
Wherein the userspersonal information comprises telephone directory book, note etc., and SIM network authentication information comprises the information such as SIM card sequence number, IMSI, ICCID, ki (2G), key (3G), OPC (3G), OTA, PIN, PUK.
After acquisition for mobile terminal network authentication information, initiate network registration and authentication,, if the network authentication success is validated user, can normally use the communication of voice-and-data business.After failed authentication, according to network, return to authenticating result, terminal shows " disabled user " and returns to the first step and " please again swipe the card ".
In the invention process, described operational order is except for the start-up command of swiping the card, can also be the network bound instruction, when described operational order is the network bound instruction, operator's service terminal read the SIM card that is independent of mobile terminal the SIM card sequence number, want IMEI and the user profile of the mobile terminal of binding with this SIM card;
Described operator service terminal generates KI according to the described SIM card sequence number that reads, described IMEI and described user profile;
Described operator service terminal writes described KI respectively in the mobile terminal of SIM card and wish and the binding of this SIM card, simultaneously the IMEI of described KI and mobile terminal is saved in mobile network service device HLR.
If current mobile terminal is not for binding the network terminal, netkey is defaulted as " 0 ", after mobile terminal-opening, while initiating the network authentication application, uses the IMEI number of terminal as network authentication, and whether retrieve this terminal IMEI be legal terminal.
Wherein, the terminal IMEI number is the unique identifier of terminal, and terminal is dispatched from the factory identified.
Non-legal terminal definition: IMEI number length is illegal, and IMEI number producer discrimination bit None-identified, IMEI number have carried out network bound.
In the embodiment of the present invention with the terminal IMEI number as network authentication, preventing that the lawless person from using violent means carries out mobile phone upgrade, the IMEI number of mobile terminal KI clear " 0 ", and reaches the purpose that cracks network authentication, and if will be regarded as illegal terminal by clear " 0 ".
In addition, when operational order is first while unbinding instruction, mobile terminal will be stored in its inner equal zero clearing of encrypted authentication code, and will be stored in its inner authentication flag zero setting;
Described mobile terminal sends encrypted authentication code clear command and authentication flag zero setting instruction by wireless radio frequency mode in SIM card;
SIM card according to the described close authentication code clear command that receives and authentication flag zero setting instruction respectively with the equal zero clearing of encrypted authentication code in SIM, and with the authentication flag zero setting in SIM card.
Further, mobile terminal unbinds after instruction and can point out the user to input user cipher receiving first, and described user cipher can be the startup password that arranges of user oneself or the password of revising authority, the legitimacy of the operation that guarantees thus to unbind.
Wherein first instruction that unbinds is the mode that normally unbinds, mainly by mobile terminal, realize, mobile terminal will be stored in the encrypted authentication code zero clearing in its storer, mode by less radio-frequency will be stored in the equal zero clearing of encrypted authentication code in SIM card simultaneously, simultaneously with the authentication flag zero setting in SIM card.
Except normally unbinding,, if when mobile terminal is lost, can not unbind normally by first instruction that unbinds, need this moment second instruction that unbinds to carry out improperly unbinding.
Particularly, described operational order is second while unbinding instruction, operator's service terminal detects the authentication flag of SIM card by wireless radio frequency mode, and the described authentication flag that will detect is set to by force zero, so can realize unbinding of lost customer terminal.
In addition, if when SIM card is lost, can carry out the improper instruction of going by the 3rd operational order, operator's service terminal detects the authentication flag of mobile terminal by wireless radio frequency mode, and the described authentication flag that will detect is set to by force zero, so can realize losing unbinding of SIM card.
SIM card application inductive coil of the present invention carries out wireless data read-write and identification.Owing to being the noncontact communication, read write line just can operate card in the 10cm scope, thus needn't the plug card, and very convenient user uses.Contactless card does not have directivity while using, card can be read and write by any direction, gets final product complete operation, and this has improved the speed of each use greatly; Reliability is high, and between contactless SIM card and read write line, machinery-free contacts, and has avoided the various faults that produce due to the contact read-write.Such as: therefore the fault that causes the reason such as loose contact to cause due to roughly plug-in card, the insertion of non-card foreign object, dust or greasy dirt can allow SIM card from then on break away from the puzzlement that causes the None-identified SIM card because of the loose contact of draw-in groove copper sheet.
No longer be confined to size and the form of draw-in groove and chip due to the volume of SIM card, SIM card internal memory ROM design can be freer, the chip research and development are joined by the producer that is fit to more storage core card, and capacity can be larger, preserves more user and terminal data.
The integrated use of multi-service, be integrated in the same card as mass transit card, social security card, Payment Card, grease card, mess card or work certificate etc., is convenient to promoting service and preferential policy binding.
SIM card can be configurable without binding, binding one to one and three level of securitys of network bound according to the needs of business:
1, common-mode, the configuration mode that namely dispatches from the factory, after general soft SIM card is dispatched from the factory, default setting is " not binding " state, the same with the hard SIM card of present use, encrypt with authentication arithmetic also constant, with all terminals of market can be general (except the terminal of binding SIM).As long as in SIM card, certain remaining sum is arranged, except the mobile phone terminal of binding network, the terminal of any market can be opened, but a station terminal can only be opened at every turn, can not open simultaneously many, because phone number only has one.Common-mode is applicable to mobile phone and peddles the business and carry out the demonstration of terminal test and model.
2, binding authentication pattern (comprising one to one and network bound), consider that SIM card separates use with mobile terminal, in order to improve security, the design concept of soft SIM card is can be on the basis of original communication authentication, the tripartite who realizes SIM card information, user profile and end message binds bi-directional authentification, that is to say,, if SIM card is stolen or copied to the undesirable, can not use this SIM card on other terminal; If mobile phone terminal is given theft, the SIM card that should not bind, terminal can not be used by normal boot-strap equally, and the user also can arrange startup password simultaneously, even if SIM card and terminal are given theft simultaneously, terminal also can't be used.And hard SIM card in the past can not realize terminal binding, if stolen, personal information (as phone number, note etc.) can't ensure, soft SIM card can realize the binding authentication, will solve this difficult problem.
One card multiple terminals binding,, by apply for handling " all-purpose card " business in business hall, can realize a card multiple terminals binding function, when using 3G(TD or LTE card of surfing Internet) time, a SIM card or the SIM card of pulling out original mobile phone just need not be applied for more; Beat and can beat mutually (552,553) by cornet mutually in the jack per line net; When a number is got to another number, only add follow-up (1,2,3) and just can distinguish different mobile phone terminals, if the user does not know that another user opens " all-purpose card " business, when dialing this number, have voice suggestion, " make Lee XX, please by 1; Make an XX, please by 2 ".Realize a buckle expense, greatly alleviate the pressure that mobile number uses, also greatly alleviate the burden of this record of number.
