Wherein, the first chip can be specially paste card, and now, the second chip can be specially the smart cards such as the SIM card that is connected with paste card or usim card, and in embodiments of the present invention, the paste card of all take describes as example.
Generally, special instruction comprises: be used for wiping the switching command switching between the erasing instruction of card, the double card pattern simultaneously used at paste card single deck tape-recorder pattern and paste card and smart card and the initialization directive that is used for refreshing instruction list etc., these special instructions are processed by paste card, certainly, those skilled in the art, when concrete application, can also arrange according to actual conditions such as used chip and required functions other special instruction.
According to instruction type, distinguish, non-special instruction specifically comprises: special proactive command and APDU(Application Protocol Data Unit, Application Protocol Data Unit) instruction, wherein, special proactive command specifically comprises again: Terminal Profile(terminal summary info download instruction), Envelop(download instruction), Fetch(obtains instruction) and the instruction of Terminal Response(terminal response).In paste card, after determining instruction type, by the command process module of respective type, this instruction is processed.
For example, as shown in Figure 2, paste card receives the flow process of carrying out after instruction and comprises:
The instruction that step S201, receiving terminal send;
Whether the instruction that step S202, judgement receive is special instruction, if so, and execution step S204, if not, execution step S203;
Step S203, judgement, at present whether in single deck tape-recorder pattern, if so, perform step S204, if not, execution step S205, wherein, single deck tape-recorder pattern refers to the pattern of only using paste card not use smart card, and corresponding double card pattern refers to the pattern that paste card and smart card are used simultaneously with it;
Step S204, directly by the instruction distribution module of paste card, instruction is processed;
The type of step S205, decision instruction, when instruction type is basic APDU instruction type, execution step S206, when instruction type is Terminal Profile instruction type, execution step S207, when instruction type is Envelop instruction type, execution step S208, when instruction type is Fetch instruction type, execution step S209, when instruction type is Terminal Response instruction type, execution step S210, when type that instruction type is other special proactive command, execution step S211;
Step S206, by basic APDU command process module, this instruction is further processed;
Step S207, by Terminal Profile command process module, this instruction is further processed;
Step S208, by Envelop command process module, this instruction is further processed;
Step S209, by Fetch command process module, this instruction is further processed;
Step S210, by Terminal Response command process module, this instruction is further processed;
Step S211, by other Special Main dynamic formula command processing module, this instruction is further processed.
When instruction is basic APDU instruction, by basic APDU command process module, this instruction is further processed: when paste card and smart card all do not have data to take out, directly basic APDU instruction is passed through to intelligent card in processing, that is: basic APDU instruction is sent to intelligent card in processing, and the data retransmission directly smart card being returned is to terminal; While having data to take out in paste card or smart card, basic APDU instruction is carried out to half transparent transmission: paste card sends to intelligent card in processing by basic APDU instruction, and after receiving the status word that smart card returns, this status word is revised as to the corresponding status word of length of the required data that read, then by amended data retransmission to terminal.
Concrete, as shown in Figure 3, the basic APDU instruction of half transparent transmission specifically comprises:
Step S301, basic APDU instruction is sent to smart card;
The status word that step S302, reception smart card return;
Step S303, the status word returned of judgement represent not have the status word 9000 to be read such as data or sign to have data to wait for the status word of reading state if so, to perform step S304, if not, directly perform step S305;
Step S304, according to paste card, record etc. the situation of data to be read, revise the status word that smart card returns, and continue execution step S305;
Step S305, to terminal return state word.
For example: paste card detects paste card or smart card in busy condition, and having length is XX
1data need to take out, paste card also can send to smart card by instruction, and the data analysis that smart card is returned: if smart card is received return state word 9000 after instruction, represent that smart card does not need reading out data, paste card is changed into 91XX
1, and return to terminal; If smart card is received return state word 91XX after instruction
2, represent that it is XX that smart card need to read length
2data, paste card is still revised as 91XX according to the detection of self by this status word
1, and return to terminal; If return to other status words (as status word error), paste card is directly returned to terminal.
When instruction is Terminal Profile instruction, by Terminal Profile command process module, this instruction is further processed: instruction is sent to smart card, and receive the rreturn value of smart card; Analyze the rreturn value of smart card, generate corresponding state word and send to terminal.
Concrete, when the rreturn value of smart card represents there is no data to be read, paste card generates menu data according to self menu, and to terminal, returns to the status word of sign menu data; When the rreturn value of smart card indicates data to be read, paste card takes out the data to be read in smart card, when taken out intelligent card data is menu data, according to self menu, revise the menu data taking out, menu data after memory modify, and to terminal, return to the status word of the amended menu data of sign, when taken out intelligent card data is not menu data, data cached and to terminal, return to the status word of identification data.
For example: according to setting in advance, when the key word that recognizes presentation directives's classification when paste card is A010, can determine that this instruction is Terminal Profile instruction, as shown in Figure 4, Terminal Profile command process module is processed this instruction:
Step S401, Terminal Profile instruction is sent to smart card;
The rreturn value that step S402, reception smart card return, according to setting in advance, when rreturn value is 9000, represent not have data to be read, continue execution step S403, when rreturn value is 91XX, indicate that length is the data to be read of XX, performs step S404;
Step S403, paste card generate menu data according to self menu, and to terminal, return to the status word of sign menu data;
Step S404, paste card take out the data that in smart card, length is XX, when paste card takes out the data in smart card, can send Fetch instruction to smart card and take out data;
Whether the data that step S405, judgement are taken out are menu data, if so, continue execution step S406, if not, execution step S407;
Step S406, according to self menu, revise the menu data taking out, the menu data after memory modify, and to terminal, return to the status word of the amended menu data of sign;
The data that step S407, buffer memory take out are also returned to sign to terminal to have length are the status word 91XX of the data to be read of XX, wait for that terminal receives to send Fetch instruction after this status word and take out this data.
In step S405, can judge according to setting in advance whether taken out data are menu data, for example can be set as menu data sends by proactive command SETUPMENU, if the data of taking out are SETUPMENU order, can be judged as menu data, if the data of taking out are not SETUPMENU orders, can judge that these data are not menu datas.
When instruction is Envelop instruction, by Envelop command process module, this instruction is further processed: according to the key word in instruction, determine the transmission object of instruction; When instruction is the instruction that sends to paste card, and smart card is when idle condition, and paste card is directly processed instruction; When instruction is the instruction that sends to smart card, and paste card is when idle condition, and paste card is transmitted to smart card by instruction and processes; When instruction is while sending to the instruction of paste card and smart card in busy condition, if instruction is the PPDownload instruction for point-to-point downloading data, the paste card buffer memory instruction wait smart card free time directly processes afterwards, otherwise abandon this instruction, or paste card also can not carry out this judgement, when instruction is while sending to the instruction of paste card and smart card in busy condition, the direct buffer memory instruction wait smart card free time of paste card directly processes afterwards; When instruction is while sending to the instruction of smart card and paste card in busy condition, if instruction is the PPDownload instruction of point-to-point downloading data, the instruction of paste card buffer memory waits for that paste card is transmitted to smart card by instruction after the free time and processes, otherwise abandon this instruction, equally, paste card can not carry out this judgement, and when instruction is while sending to the instruction of smart card and paste card in busy condition, the direct buffer memory instruction of paste card waits for that paste card is transmitted to smart card by instruction after the free time and processes.
Conventionally, when paste card or smart card send to terminal, indicates after status word that data need to take out, paste card or smart card be in busy condition, after receiving the Terminal Response instruction that terminal sends, and paste card or smart card recovery idle condition.
For example, when returning to terminal, paste card or smart card indicate that after status word 91XX that the data of XX length need to take out, paste card or smart card enter busy condition, until receive the Terminal Response instruction that terminal sends, just finish busy condition, enter idle condition.For example, smart card has the data of 35 bytes to need to take out, and can send 9135 to terminal, then enters busy condition until receive the Terminal Response instruction that terminal sends, and just finishes busy condition, enters idle condition.
For example: according to setting in advance, when the key word that recognizes presentation directives's classification when paste card is A0C2, can determine that this instruction is Envelop instruction, as shown in Figure 5, Envelop command process module is processed this instruction, comprising:
Step S501, according to the key word in instruction, judge this instruction transmission to as if smart card or paste card, if smart card, execution step S502, if paste card performs step S504;
