Description
Technical Field
The application relates to the technical field of communication, in particular to a smart card, a terminal and a smart card terminal communication system.
Background
A Universal Subscriber Identity Module (UICC) is a multifunctional smart card that can run various logic applications, such as: subscriber Identity Module (SIM), User Identity Module (UIM), Universal Subscriber Identity Module (USIM), IP Multimedia Service Identity Module (ISIM), CDMA2000 Subscriber Identity Module (CSIM, CDMA2000 Subscriber Identity Module), and the like. Of course, the UICC card may also run other applications, such as: electronic purses, electronic cash, subways, public buses, and the like. In addition, one UICC card can be loaded with a plurality of applications such as USIMs, ISIMs and CSIMs. Therefore, the UICC card can be suitable for various terminals, is accessed into a 2G/3G/4G/5G mobile network, is used for swiping cards in various POS machines and the like, and really realizes one card with multiple functions.
After the terminal is started, the terminal can perform a series of command interaction with the UICC card, reads related information from the UICC card to perform terminal initialization, and initializes the UICC card at the same time. Taking the USIM as an example, after the terminal is powered on, a series of complex process interactions are performed between the USIM and the terminal, for example: USIM management procedures, USIM security related procedures, user related procedures, etc. refer to the specifications in (3GPP TS 31.102V16.2.0, section 5Application Protocol) in detail, during which hundreds or even thousands of apdu (Application Protocol Data unit) command interactions are performed between the terminal and the USIM. Taking CSIM as an example, after the terminal is powered on, a complex process interaction will be performed with CSIM, such as: the CSIM management process, the CSIM security-related process, the user-related process, etc. refer to the specification in section 2 (3GPP2 c.s0065-B, 7Application Protocol), during which hundreds or even thousands of apdu (Application Protocol Data unit) command interactions are performed between the terminal and the CSIM. Other types of applications, for example: the SIM, UIM, ISIM and the like, after the terminal is started, the terminal can also initiate a series of initialization processes according to the relevant specifications to carry out a series of APDU interactions. However, after the terminal is powered on, a series of command interactions between the terminal and the UICC card consume both time and power, thereby affecting user experience and reducing standby time of the terminal.
In order to save power consumption, when the terminal does not need to use the UICC card for application, the terminal can send a suspension instruction to the UICC card, the UICC card can cache the current working environment and variables, and then the terminal powers off the UICC card, so that the power consumption of the UICC card to the terminal is reduced; when the terminal needs to be applied to the UICC card next time, in order to save the time for initializing the UICC card, the terminal sends a recovery instruction to the UICC card after powering on the UICC card, and according to the work environment and variables cached before recovery of the UICC card by the recovery instruction, the flow refers to the specification in the third paragraph (ETSI TS 102221V16.1.0, section 11.1.22SUSPEND UICC). Therefore, after the terminal powers on the UICC card, the UICC card can be used without a series of process interaction, so that the time is saved, and the power consumption is reduced.
However, the existing UICC card can only cache a set of working environment and variables, and for a terminal supporting multiple working modes and a UICC card supporting multiple working modes, if the terminal needs to switch the working mode of the UICC card, the UICC card needs to store the current working environment and variables, then the terminal re-initializes another application in the UICC card, and performs a series of interactions with the UICC card, so that the switched new application can be used. If the terminal frequently switches the working environment, the terminal repeatedly performs initialization interaction with the application on the UICC card, which consumes time and wastes the electric quantity of the terminal.
Therefore, how to make the UICC card running with multiple applications reduce the power consumption of the terminal and reduce the time consumed for switching the applications in the UICC card is a technical problem to be solved by those skilled in the art.

specifically, if the obtained IMEI of the terminal is not consistent with the IMEI stored in the smart card identification information storage space 110 (specifically, the obtained IMEI of the terminal is not consistent with the IMEI actually stored in the smart card identification information storage space 110, or if the obtained IMEI of the terminal is not stored in the smart card identification information storage space 110 and the obtained IMEI of the terminal is not necessarily consistent with the data stored in the smart card identification information storage space 110), the IMEI stored in the smart card identification information storage space 110 and the network operator application name, the operating environment, the variables, and the recovery token stored in each smart card recovery information storage space are deleted to empty the smart card identification information storage space 110 and each smart card recovery information storage space if the obtained IMEI of the terminal is not stored in the smart card identification information storage space 110 and the obtained IMEI of the terminal is compared with the data stored in the smart card identification information storage space 110, or the last initialization of the smart card 100 is not completely completed, waiting for the initialization of the smart card by the terminal 200.
The terminal 200 performs the following initialization operations on the smart card 100:
the terminal sends an initialization instruction to the smart card;
in particular, the terminal 200 sends an initialization instruction to the smart card 100 to activate various network operator applications on the smart card 100.
The intelligent card sequentially operates the network operator application on the intelligent card according to the initialization instruction, stores the application name, the working environment, the variable and the recovery token of the network operator into the corresponding intelligent card recovery information storage space, and stores the IMEI of the terminal into the intelligent card identification information storage space after storing the application name, the working environment, the variable and the recovery token of the network operator;
specifically, if the smart card 100 loaded into the terminal 200 is a new card for the first time, the smart card identification information storage space 110 and the smart card recovery information storage space of the smart card 100 do not store data, the IMEI is written into the idle smart card identification information storage space 110, and the network operator application name, the working environment, the variable, and the recovery token applied by each network operator are written into the idle smart card recovery information storage space; if the smart card 100 installed in the terminal 200 is an old card that has been used, then the data is already stored in both the smart card identification information storage space 110 and the smart card recovery information storage space of the smart card 100, then the IMEI is written into the smart card identification information storage space 110 where the data is already stored to replace the original data, the network operator application name, the working environment, the recovery token of each network operator application is written into the smart card recovery information storage space where the data is already stored to replace the original data, after all the network operator applications on the smart card 100 run and the network operator application name, the working environment, the variables, and the recovery token are written into the corresponding smart card recovery information storage space, the IMEI of the terminal is stored into the smart card identification information storage space, and the initialization of the smart card 100 is completed.
