Description
Technical field
The present invention relates to mobile communication technology, particularly a kind of method of identification terminal card and device.
Background technology
The existing Universal Integrated Circuit Card (UICC:Universal IntegratedCircuit Card) that is used for mobile communication; According to different access instructions, can be divided into: subscriber identification module (SIM:Subscriber Identity Module) card and USIM (USIM:UniversalSIM) card; Wherein, SIM can comprise the subscriber identify module card (UIM:User Identity Model) of the code division multiple access (CDMA:Code-Division Multiple Access) of follow-up developments.
After dual-mode terminal inserted the UICC card, start powered on, and dual-mode terminal sends reset request and gives terminal card, and waited for the reset answer ATR that this terminal card sends.Wherein, This ATR can carry the electrical characteristic parameter that some terminal cards are supported, for example parameters such as clock rate conversion factor FI, baud rate regulatory factor DI, program current I magnitude of voltage U, Additional Protection time N, clock stop mode X and transport protocol parameters T.
After dual-mode terminal obtains above-mentioned ATR; Dual-mode terminal can determine whether to carry out protocol parameter according to the parameter that this ATR carries and select (PPS:Protocol and Parameter Select) process, so that the concrete parameter such as transport protocol type, clock rate conversion factor FI, baud rate regulatory factor DI and the Additional Protection time N that use in further definite and the terminal card communication.Wherein, the PPS process is an optional process, only in satisfying prior art, triggers the pre-conditioned of PPS process, just can further carry out the PPS process.Above-mentioned pre-conditioned can comprising: terminal card is supported the transport protocol type more than 2 kinds; Perhaps, the frequency of terminal card support is different with the frequency and the baud rate of baud rate and host-host protocol acquiescence; Perhaps, the guard time of terminal card is FF.
But, after accomplishing initial communication ATR and PPS, can not confirm the Card Type of the terminal card that dual-mode terminal is corresponding.Therefore; In the prior art; Dual-mode terminal is attempted sending different instructions usually and is given terminal card so that discern the Card Type of this terminal card; Be specially: send a USIM instruction or SIM command terminal card, and judge that further whether this terminal card has correct response is the USIM response of corresponding USIM instruction or SIM instruction or the Card Type that SIM responds the identification terminal card.In addition; Dual-mode terminal also will combine the application characteristic on this terminal card, auxiliary judgment in addition, such as; If terminal card is SIM, need judge then whether this terminal card comprises the professional associated documents of global system for mobile communications (GSM) and whether other relevant critical files exist and effectively.As for how to judge, each manufacturer terminal can design the corresponding judgment rule voluntarily based on the ability at own terminal, does not have unified standard and principle.
Generally, SIM is bound to respond the SIM instruction, and must comprise the relevant file (like DF_7F20 or DF_7F21) of gsm service; Usim card is bound to respond the USIM instruction, and must comprise 3G application (ADFUSIM).But it is corresponding one by one that the 3GPP agreement does not have mandatory provision terminal card and instruction, such as, SIM also might support USIM instruction, usim card also might support SIM instruction, usim card also might comprise GSM application etc.Like this, adopting this trial of prior art to send different instructions comes the method for identification terminal Card Type will have following problem:
The mode of the first, attempting through instruction might take place to cause erroneous judgement unusually.Now the usim card of earlier version on the market uses speed and its communication supported among the ATR, occurs just having for a long time response or can't normal response in the effective time that agreement is stipulated easily.This phenomenon can't respond USIM with some SIM and instruct performance the same, actually will cause dual-mode terminal under this abnormal conditions, to be difficult to correct differentiation SIM, or usim card.
The second, attempt the state that different instructions may influence terminal card.Such as, some terminal card can be supported SIM and USIM instruction, but in case after selected a kind of instruction, the instruction of generally attempting with article one is as the criterion, the another kind instruction is not just had response.Like this, if there is dissimilar instructions to switch, terminal card possibly can't correctly respond, and then causes terminal card normally to be identified and to use.
Three, attempt different instructions and can bring extra burden.Some terminal card must reset in dissimilar instruction is switched again, otherwise correct response instruction.Like this, these additional operations may not be inconsistent with the uniformity test that the terminal networks as resetting, and then bring implacable contradiction for the compatibility and the standardization of dual-mode terminal.

TCK：51。
This shows that present embodiment can be confirmed the Card Type of terminal card suggestion according to interface byte TB3; Like this, which kind of instruction the terminal clearly need send and give terminal card, needn't carry out the PPS process.
Step 402 judges whether above-mentioned preset byte can specifically confirm the Card Type of terminal card suggestion, if, execution in step 403, otherwise, execution in step 405.
In the present embodiment, force to carry out under the condition of PPS process with terminal card at the terminal, if above-mentioned interface byte TB3 can confirm the Card Type of terminal card suggestion, then after, execution in step 403, otherwise, execution in step 405.
Step 403 judges whether the terminal forces to carry out the PPS process with terminal card, if, execution in step 404, otherwise, the PPS process omitted, directly execution in step 407.
In the present embodiment, although can confirm the Card Type that terminal card is advised based on above-mentioned ATR,, as long as then necessary execution PPS process is forced to carry out the PPS process with terminal card in the terminal.
In the present embodiment, if can confirm the Card Type that terminal card is advised based on above-mentioned interface byte TB3; Afterwards, if the terminal does not force to carry out the PPS process with terminal card, then which kind of instruction the terminal clearly need send and give terminal card, needn't carry out the PPS process, directly execution in step 407.
Step 404 is carried out the PPS process, the Card Type of the step of going forward side by side card terminal card suggestion.
In the present embodiment, carry out the PPS process, the Card Type of the step of going forward side by side card terminal card suggestion can for:
A, terminal are sent PPS and are asked to terminal card.
In the present embodiment, above-mentioned PPS request can comprise: clock rate conversion factor FI, the required parameter that baud rate regulatory factor DI and Additional Protection time N etc. are preset.
B, terminal card send to the terminal with the PPS response of the said PPS request of correspondence, the preset byte that is used to indicate the first-selected Card Type of terminal card suggested terminals in said PPS response.
In the present embodiment, above-mentioned PPS response can comprise and the consistent parameter of above-mentioned PPS request, and the form of above-mentioned PPS response can be identical with the form of above-mentioned PPS request.
In said PPS response the preset byte that is used for indicating the first-selected Card Type of terminal card suggested terminals can for: the PPS3 based on the PPS response comes the first-selected Card Type of indicating terminal card suggested terminals.Such as, PPS3 is 01 o'clock, the first-selected Card Type of indicating terminal card suggested terminals is a usim card; PPS3 is 10 o'clock, and the first-selected Card Type of indicating terminal card suggested terminals is a SIM.
C, when the Card Type of above-mentioned first-selection is consistent with the Card Type of above-mentioned suggestion, further verified the Card Type of terminal card suggestion.
In the present embodiment; If above-mentioned interface byte TB3 confirms that the Card Type of terminal card suggestion is a usim card; And the Card Type first-selected as if PPS3 indicating terminal card suggested terminals is usim card among the step B; Then the Card Type of said first-selection is consistent with the Card Type of said suggestion, has further verified the Card Type of terminal card suggestion.Generally, the Card Type of above-mentioned first-selection and the inconsistent situation of Card Type of above-mentioned suggestion can not appear.Certainly; If the Card Type of the Card Type of above-mentioned first-selection and above-mentioned suggestion is inconsistent; Then can be as the criterion, perhaps, be used for being as the criterion of the first-selected Card Type of indicating terminal to preset in the response parameter with the Card Type of byte indicating terminal card suggestion preset among the ATR; Concrete condition is carried out after need passing through concrete analysis by appointment.
In the present embodiment, if PPS response is consistent with parameter in the PPS request, the parameter in responding as if PPS can be represented as follows:
FF?50?95?01?3B
Wherein:
PPSS：FF；
PPS0:50 representes that PPS1 PPS3 exists, and protocol type is T=0;
PPS1:95 representes to use the flank speed of current terminal card support;
PPS3:01 representes that the Card Type of terminal card suggestion is a usim card;
PCK：3B。
It is thus clear that, according to above-mentioned PPS3, can know that also the first-selected Card Type of terminal card suggested terminals is a usim card, further verified the Card Type of above-mentioned terminal card suggestion.
Step 405 judges whether the terminal forces to carry out the PPS process with terminal card, perhaps; Judge whether to satisfy the existing pre-conditioned of triggering PPS process, if, execution in step 406; Otherwise, carry out the operation of prior art through the method identification terminal Card Type of trial instruction.
