Problems solved by technology

For a telecom smart card with a small file system, it does not take long to produce a telecom smart card by applying the above scheme, but as the storage capacity of the telecom smart card data storage area 13 continues to increase, it increases from the original 8K bytes to 64K bytes, or even 128K Byte, when the above scheme is used to produce telecom smart cards, the production time is too long, which reduces the production efficiency of telecom smart cards and is not conducive to the mass production of telecom smart cards

[0030] see image 3 When using this embodiment to produce a telecom smart card, it is first necessary to use a traditional production method to produce a master card. When making the mother card, take a blank telecom smart card, and write the operating system program into the code storage area of ​​the telecom smart card. Before writing the operating system program, it is necessary to execute step S11, and set two instructions in the operating system program, which are the data read instruction and the data write instruction. The format structure diagram of the two instructions is as follows: Figure 4 and Figure 5 shown.

[0031] The data read command includes a command header "C0D8", indicating that the command is a data read command. "P1" and "P2" in the command represent the high and low bytes of the starting address of the data storage area to be read, respectively, and "length" represents the length of the data byte to be read. For example, the instruction "C0D80100...

[0045] see Figure 7 , Apply this embodiment to produce a telecom smart card, first make a mother card. When making a master card, write an operating system program into a telecom smart card, set a data read command in the written operating system program, and execute step S21. The data read command is the same as the data read command of the first embodiment, and will not be repeated here.

[0046] After setting the data read command, execute step S22, download the operating system program to the code storage area of ​​the telecom smart card, run the operating system, apply the batch processing command of the operating system to create the file system and update the data, and complete the production of the mother card.

[0047] Then, execute step S23, use the data readout command in the operating system program to read all the data in the data storage area, and copy to form a mirror image file, and perform check calculation on the mirror file at the same time to calculate an...

Abstract

The invention provides a method for improving the production efficiency of a telecommunication smart card. The telecommunication smart card is provided with a storing device comprising a code storage area and a data storage area. The method comprises the following: a step of making a master card, which comprises: writing an operating system program into the code storage area of the storing deviceof a blank telecommunication smart card, and creating a file system and updating data in the data storage area when the operating system is operated; a step of making an image file, which comprises: reading out and copying the data stored in the data storage area of the master card to form the image file; and a step of making the telecommunication smart card, which comprises: writing the operatingsystem into the code storage area of the storing device of each telecommunication smart card, and writing the image file into the data storage area of the storing device of the telecommunication smart card. The method can reduce the time of creating a file system and updating data so as to shorten the time of generating each telecommunication smart card and improve the production efficiency of the telecommunication smart card.

Description

technical field [0001] The invention relates to a production method of a telecommunication smart card, in particular to a production method capable of improving the production efficiency of a telecommunication smart card. Background technique [0002] With the popularity of smart cards, smart cards have been widely used in fields such as mobile communications and e-commerce, among which the more common ones are telecom smart cards that are installed on mobile phones and communicate through wireless communication networks, such as SIM cards (Subscriber Identity Model, Subscriber Identity Module) . [0003] The existing telecom smart card has a memory, and its structural block diagram is as follows figure 1 shown. The memory 10 of the telecom smart card includes a boot loader storage area 11 , a code storage area 12 and a data storage area 13 . Wherein the boot loader storage area 11 is mostly a read-only memory (ROM), which stores a boot loader (Boot Loader) of a telecom s...
