Embodiment
The telecom intelligent card of using method production provided by the invention has a storer, this storer includes boot loader memory block, code storage district and data storage area, and wherein the boot loader memory block writes the boot loader that semiconductor producer provides in advance.When producing telecom intelligent card, need be in the code storage district write operation system program, and in the data storage area, write file system and new data more.
First embodiment:
Referring to Fig. 3, when using present embodiment production telecom intelligent card, at first need to use traditional production method and make a master card.When making master card, get the telecom intelligent card of a blank, and operating system program is written in the code storage district of this telecom intelligent card.Before the write operation system program, needing execution in step S11, two instructions are set in operating system program, is respectively that data sense order and data write instruction, the format structure figure of two instructions such as Fig. 4 and shown in Figure 5.
The data sense order includes instruction head " C0D8 ", represents that this instruction is the data sense order." P1 " and " P2 " represents the high and low byte of the data storage area start address of reading respectively in the instruction, and " length " need to represent the length of sense data byte.For example instruct " C0D8010080 " to represent 0x80 the byte data that begins from address 0x0100 in the reading of data memory block.
In the same manner, data write instruction and include instruction head " C0DA ", and " P1 " and " P2 " represents the high and low byte of the data storage area start address that writes respectively, and " length " represents to write the length of data.In the data storage area, in 0x80 the byte that address 0x0100 begins, write data [data] as instruction " C0DA010080[data] " expression.Certainly, data are set write when instruction, [data] data for reserving write image file wherein after waiting to make image file.
After data sense order and data are set write instruction, execution in step S12, operating system program is downloaded in the code storage district of telecom intelligent card, and operation system, the a series of processing batch instruction of application operating system are created file system and new data more, and these are identical with existing telecommunication intelligent card production method.So far, master card is made and is finished.
After the master card that completes, the data sense order of application operating system is read all data in the data storage area of master card, after reading it is duplicated to form an image file, i.e. execution in step S13.Preferably, the image file of reading is done verification calculate,, calculate an expectation proof test value as CRC check or other verifications.
When making image file, master card is inserted in the card reader, allow master card operation system, carry out the data sense order in batches by the memory block sequence of addresses, and the data of reading are sent to card reader, the content of reading is preserved in order the file of forms such as txt, promptly form an image file.
Then, batch making telecom intelligent card.At first, write operation system program in the code storage district of each blank telecom intelligent card of producing in batches, i.e. execution in step S14, this system pack is drawn together above-mentioned data and is write instruction.Then, execution in step S15, application data writes instruction image file is written in the data storage area of each telecom intelligent card.
After each telecom intelligent card writes image file, each data that write the data storage area is done verification, calculate a proof test value, and execution in step S16, judge whether the proof test value that calculates is consistent with the expectation proof test value that image file calculates, and correctly is written in the data storage area as if the consistent image file of representing, then execution in step S17, with the individuation data of telecom intelligent card, write in the telecom intelligent card as ICCID sign indicating number, PIN code etc.
If the proof test value that the data computation of data storage area goes out is inconsistent with the expectation proof test value, mistake appears in expression when writing image file, and execution in step S18 then returns the information of image file write error, reminds smart card production firm to write image file again.
This shows, during the batch making telecom intelligent card, do not need to create file system and reach more new data, but file system is directly write in the data storage area by the mode that writes image file by traditional mode.Owing to do not need to carry out a series of discriminating step when writing image file, significantly reduce the establishment file system and reach the time that more new data consumed, thereby reduce the production time of telecom intelligent card, improve the production efficiency of telecom intelligent card.
In the present embodiment, data sense order and data write the high low byte that " P1 ", " P2 " expression addressing are used in instruction respectively, and its maximum address address is 0xFFFF, and promptly maximum can only read or write the 64K byte data.If data, then need the data page in the data storage area is read or write as the 128K byte greater than the 64K byte in the data storage area, can set every page data length is the 64K byte.A page marker instruction need be set simultaneously, to identify the not data of same page in operating system program.
The page marker order format that operating system program is provided with as shown in Figure 6, wherein " P3 " is page marker, if the data of reading or writing are first page data, then " P3 " byte is set to " 01 ", if the data of reading or writing are second page data, then " P3 " byte is set to " 02 ".
Like this, when reading the master card data, operating system is read the data of data storage area respectively according to page marker, and forms the image file of multipage.During the batch making telecom intelligent card, operating system writes respectively in the corresponding storage area according to the image file of page marker with multipage, realizes writing greater than the 64K byte data thus.
In the present embodiment, data are set in operating system program write instruction and image file is write in the telecom intelligent card of batch process, can also realize writing of image file by the application start loading procedure during practical application.
Second embodiment:
Referring to Fig. 7, use present embodiment and produce telecom intelligent card, at first make master card.When making master card, write operation system program in a telecom intelligent card is provided with the data sense order in the operating system program that writes, i.e. execution in step S21.The data sense order is identical with the data sense order of first embodiment, does not repeat them here.
After the data sense order was set, execution in step S22 was downloaded to operating system program in the code storage district of telecom intelligent card, and the operation system, and the processing batch instruction of application operating system is created file system and new data more, finishes the making of master card.
Then, execution in step S23, the data sense order in the application operating system program is read all data in the data storage area, and duplicates the formation image file, simultaneously image file is done verification and calculates, and calculates an expectation proof test value.
Then, produce telecom intelligent card in batches, the raw data in the application start loading procedure writes instruction, operating system program and image file is written in the storer of telecom intelligent card in the lump, i.e. execution in step S24.Behind write operation system program and the image file, divide the code storage district and the data storage area of storer, and the virtual address of data storage area is set, start address is the termination address of code storage district physical address in the virtual address of data storage area.
For example, the termination address of operating system program is 0x9180, and then the termination address in code storage district also is 0x9180, and the start address 0x0000 of data storage area virtual address also is 0x9180 with respect to the address of whole storer.
Behind the dividing data memory block, data in the checking command data memory area in the application start loading procedure are done verification and are calculated, the calculation check value, and execution in step S25, judge whether the proof test value that calculates is consistent with the expectation proof test value, if consistent, the expression image file correctly is written in the data storage area, and execution in step S26, the individuation data of telecom intelligent card is write.If inconsistent, expression makes a mistake when writing image file, and execution in step S27 then sends the warning message of image file write error.
This shows, during present embodiment medium quantity batch processing telecom intelligent card, create file system and new data more by the mode that writes image file, and do not use traditional mode, the processing batch instruction of application operating system is created file system through behind a series of determining step, and the time of therefore creating file system is shorter, reduce by every telecom intelligent card production time, improve the production efficiency of telecom intelligent card.
And, present embodiment is done verification calculating respectively to image file that forms and the data that are written to the telecom intelligent card data storage area, and judge by judging that proof test value that twice verification calculate is whether consistent whether image file correctly writes, to guarantee that image file correctly writes in the telecom intelligent card, the telecommunication intelligent cacaine of avoiding producing writes the image file mistake and need scrap the generation of situation.
Certainly, the present invention can also have more variation when practical application, and the program that a specialized apparatus for example is set or develops a special use is read the data of data storage area in the master card and duplicate, and makes image file; Perhaps, write in data sense order and data and increase a byte in the instruction as page marker; Or the exploitation specific program is done verification calculating etc. to the image file that writes in the telecom intelligent card, and these do not influence enforcement of the present invention.
At last; it is emphasized that; the invention is not restricted to above-mentioned embodiment, write the change of order format, the change of page marker set-up mode, the subtle change such as change of checking algorithm such as data sense order and data and also should be included in protection scope of the present invention.
