The basic idea of the present invention is to use the loop file in the existing subscriber identity card to store the internetwork service data.

1 is a schematic flowchart of a method for storing service data according to the present invention. As shown in FIG. 1, the method includes:

Step 101: After the terminal is powered on and after normal authentication, the user identification card is initialized. After the user identification card is initialized, the terminal needs to acquire and store the index information of the loop file for storing the service data from the user identification card. Specifically, the terminal obtains an index from the latest record of the loop file for storing the service data. information.

Optionally, after the user identification card is initialized, the terminal according to the index information (such as the case where the terminal uses a single loop file to store the service data) or the preset service data and the loop identification file storage relationship table in the user identification card (such as the terminal) In the present invention, the description information of the loop file in the user identification card is stored in the corresponding loop file, and specifically, a storage is opened in the corresponding loop file in the user identification card. As the index storage area, the area always uses the last record as the index storage area. The index field is used to indicate whether each storage slot of the loop file stores the original type data (such as whether EFlnd stores the dialed number) or is stored. Business data, or empty items. An example of a definition is as follows: 0 means that a storage slot is empty data, 1 means that a storage slot stores the original data type (for EFlnd is a dialed number), and 2 indicates that a storage slot is stored. Is business data.

Step 102: In the business application, the service data needs to be stored.

Step 103: The terminal writes service data into the loop file for storing service data, and updates corresponding index information.

Here, when the terminal directly writes the service data into the loop file in the user identification card, after updating the corresponding index information stored by the terminal, the index information needs to be written into the user identification card. In the corresponding loop file, specifically, when the storage slot of the loop file is full, the storage slot that is stored for the longest time is written, and when the storage slot of the loop file is not full, the next unoccupied storage is written. groove.

After the terminal reads the cyclic file data for storing the service data into the preset storage area in the terminal after the initialization, the terminal writes the service data into the preset storage area to store the service data. In the file, and updating the index information of the loop file for storing the service data stored by itself. After that, when the terminal meets certain conditions (such as shutdown, timer expires, etc.), the content of the loop file used to store the service data in the preset storage area is written into the user identification card, and then the terminal is saved. The index information is written into the loop file in the user identification card (in accordance with the storage rule of the loop file, when the loop file storage slot is full, the index information is written into the loop file to store the longest record, the loop file storage slot If it is not full, write the index information to the next unoccupied slot in the loop file).

Correspondingly, when the terminal is powered on or the terminal is restarted, the terminal reads the latest record of the relevant loop file on the user identification card as index information and stores it.

Step 104: In the business application, the business data needs to be read.

Step 105: The terminal reads the service data stored in the loop file according to the index information.

After the terminal reads the cyclic file data of the service data into the preset storage area in the terminal after the initialization, the terminal reads the relevant storage area (preset loop file, including the index field) preset in the terminal. data.

It should be noted that, in the present invention, the terminal mainly refers to an Internet of Things terminal, and the user identification card described in the present invention may be a SIM card, a RUIM card, a USIM card, a UICC card, or the like.

The present invention also provides a system for storing service data, the system comprising a terminal and a subscriber identity card;

The terminal is configured to acquire index information of a loop file for storing service data from a user identification card and store the data, and write the service data to the storage for when the service data needs to be stored Store the business data in the loop file and update the corresponding index information.

The terminal is further configured to read, according to the index information, when the service data needs to be read Business data stored in the ring file.

The technical solutions of the present invention are further described in detail below in conjunction with specific embodiments.

Example 1

The files and data on the SIM card include the following four types:

(1) System raw data deposited by the SIM card manufacturer.

(2) Network parameters and user data injected by the network operation department or other business departments when issuing the card to the user. Such as authentication and encryption information Ki (one of Kc algorithm input parameters: key number); International Mobile Subscriber Number (IMSI); A3: IMSI authentication algorithm; A5: encryption key generation algorithm; A8: Key (Kc) generation Before, the user key (Kc) generates an algorithm or the like.

(3) Data deposited by the user himself. For example, the short message is stored in EFsms, the phone book is stored in EFadn, and there are fixed dialing, abbreviated dialing, performance parameters, and call count.

(4) Network connection and user information class data that the user automatically deposits and updates during the card use process. This includes the location identification number (LAI) of the mobile phone at the time of the last location registration, the periodic location update interval set, the Temporary Mobile Subscriber Number (TMSI), and so on.

The above data are stored in their respective directory entries. The first type of data is placed in the root directory. When the power is turned on, it first enters the root directory, and then enters the relevant subdirectory according to the instructions. Each directory has its own internal data fields. The identification code protection can only query, read and update the data in the data domain after the verification. The first type of data above is usually permanent data, which cannot be changed after being injected by the SIM card manufacturer. The second type of data is usually allowed to be accessed and updated by the specialized agencies of the network operation department. Most of the third and fourth types of data are allowed. The user performs a read/write operation on the terminal.

In this embodiment, the service data is stored in the SIM card EFlnd, EFlnd is a loop file for storing service data in the user identification card, and the loop file structure in the SIM card is as shown in FIG. 2 .

In this embodiment, the index (Index) information is always stored in the last record in the EF1nd, and the index information is used to describe the dialed number data and the service data storage of the EF1nd file. Generally, the Index information occupies a storage space of a record. Of course, two or more records can be occupied according to requirements, and the space size varies according to different user identification cards, for example, one record in a user identification card. It is 176 bytes, and some are 255 bytes.

3 is a schematic diagram of a Index area of a loop file according to Embodiment 1 of the present invention. As shown in FIG. 3, the Index area is composed of a plurality of consecutive bytes, and FIG. 4 is a loop file Index according to Embodiment 1 of the present invention. A bit bit diagram, as shown in FIG. 4, the Index area is logically composed of two components. An implementation example is to select the first byte of the Index as a flag field, which is used to indicate that the field is an Index field, and is given For specific values, such as "OxAA", this field separates Index from other records in other EFlnd. According to our scheme, three kinds of data are stored in EFlnd, one is business data, one is ordinary dialing number data, and the other is empty slot. In the remaining fields of the index, the storage data type of each storage slot is determined for every 2 bits. 00 indicates that a storage slot is empty data, 01 indicates that a storage slot stores dialed data, and 10 indicates that a storage slot stores service data. If the Bitl and Bit2 of the Index are 01, it indicates that the first slot stores the normal dialed number data. If Bit3 and Bit4 are 02, it indicates that the second slot stores the service data. If Bit5, If Bit6 is 00, it indicates that the third slot does not store data.

According to the above method, the index area of the EFlnd file is re-implemented logically, and the field of the Index area can describe the storage condition of up to 1/2*8*(N-1) EFlnd storage slots, and the value of N depends on different users. The card type is identified, but for a loop file, using a slot always describes the storage of all the records in the loop file.

5 is a schematic flowchart of reading service data according to Embodiment 1 of the present invention. After receiving a command for reading service data, the mobile terminal searches for data in a corresponding preset loop file in the terminal to perform service data reading. When the operation is read from the preset circular file, the index of the storage area of the mobile terminal is first queried, and the service data is read into the temporary storage area of the terminal according to the query result (for example, when the corresponding bit is 02), and the reading is successful, if If a loop file is not successfully read, another loop file is read according to the predetermined order of the terminal until all preset loop files are read. Otherwise the read fails.

6 is a schematic flowchart of writing service data according to Embodiment 1 of the present invention. After receiving a command for writing service data, the mobile terminal first queries an Index of a preset loop file storage area of the mobile terminal, and writes service data according to the query result. Enter a free slot in memory or overwrite a storage slot. If it is business data, change the corresponding two bits of Index to the service data identifier (an example is 02, which means that the service data is stored); When the device arrives, the content of the loop file preset in the terminal is written into the relevant EF file in the SIM, and then the Index is written into the relevant EF file on the card.

The above description is made by taking the EFLnd of the SIM card as an example. The present invention is applicable to other applications on the R-UIM, the USIM, and the UICC, and can be similarly used, and will not be described again.

The invention has the advantages that: the popularization is good, the cost is low, and the loop file of the original user identification card not used frequently in some services is effectively utilized, so that the operator does not need to re-customize the new user identification card, which is effective. Saving business costs. In actual use, the operator can also write its business data service into the previously issued user identification card through instruments or third-party software, so that the business can be conveniently carried out.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
