Problems solved by technology

[0005] However, the existing UICC card can only cache a set of working environment and variables. For a terminal that supports multiple working modes and a UICC card that supports multiple working modes, if the terminal wants to switch the working mode of the UICC card, it needs to let the UICC card store the current The working environment and variables, and then the terminal re-initializes another application in the UICC card, and a series of interactions with the UICC card can be used to use the new application after switching
Then, if the terminal frequently switches the working environment, it will repeatedly initialize and interact with the application on the UICC card, which still consumes time and wastes terminal power.

Embodiment 1

[0025] see figure 1 , figure 1 It is a schematic diagram of the smart card provided by the embodiment of this application.

[0026] The application provides a smart card 100 (preferably a UICC card in this application), including: a smart card identification information storage space 110 and a plurality of smart card recovery information storage spaces (such as figure 1 As shown, the smart card restoration information storage space 121, the smart card restoration information storage space 122...the smart card restoration information storage space 12n), the smart card information storage space 110 and each smart card restoration information storage space are non-volatile storage areas. Wherein, the total storage space of the smart card 100 is divided to obtain a smart card identification information storage space 110 and a plurality of smart card recovery information storage spaces.

[0027] The smart card identification information storage space 110 is used to store an Inter...

Embodiment 2

[0051] see figure 2 , figure 2 It is a schematic diagram of the terminal provided by the embodiment of this application.

[0052] The present application also provides a terminal 200, including: a terminal identification information storage space 210 and a plurality of terminal recovery information storage spaces (such as figure 2 As shown, the terminal recovery information storage space 221, the terminal recovery information storage space 222...the terminal recovery information storage space 22n). Wherein, the terminal identification information storage space 210 and each recovery information storage space are non-volatile storage areas. Wherein, by dividing the total storage space of the terminal 200, one terminal identification information storage space 210 and multiple terminal restoration information storage spaces are obtained.

[0053] The terminal identification information storage space 210 is used for storing an integrated circuit card identification code (Inte...

Embodiment 3

[0078] The present application also provides a smart card terminal communication system, including the above smart card 100 and terminal 200 .

[0079] After the terminal 200 is powered on, the following checking operations are performed between the terminal 200 and the smart card 100:

[0080] The terminal powers on the smart card, sends an ICCID reading command to the smart card, and compares the read ICCID of the smart card with the ICCID stored in the terminal identification information storage space;

[0081] After the terminal 200 is powered on, the terminal 200 powers on the smart card 100, and the terminal 200 sends an ICCID reading instruction to the smart card 100, and after receiving the ICCID reading instruction sent by the terminal 200, the smart card 100 sends its ICCID to the terminal 200, and the terminal 200 The ICCID sent by the smart card 100 is received and compared with the ICCID stored in the terminal identification information storage space 210 .

Abstract

The invention relates to the technical field of communication, in particular to an intelligent card, a terminal and an intelligent card terminal communication system. The intelligent card sequentially runs network operator applications on the intelligent card according to the initialization instruction, stores application names, working environments, variables and recovery tokens of network operators in corresponding intelligent card recovery information storage spaces, recovers the network operators after the application names, the working environments, the variables and the recovery tokens of the network operators are stored, stores the IMEI in an intelligent card identification information storage space, and sends an initialization completion message to the terminal, so that the terminal powers off the smart card, and sending a recovery token to the terminal, so that the terminal subsequently recovers the working environment and the variable of the network operator application running on the re-powered smart card through a recovery instruction according to the recovery token. According to the application, the power consumption of the intelligent card running a plurality of applications to the terminal is reduced, and the time consumed for switching the applications in the intelligent card is also reduced.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a smart card, a terminal and a smart card terminal communication system. Background technique [0002] Universal Subscriber Identity Module (UICC) is a multifunctional smart card that can run a variety of logic applications, such as: Subscriber Identity Module (SIM, Subscriber Identity Module), User Identity Module (UIM, User Identity Module), Universal Subscriber Identity Module (USIM, Universal Subscriber Identity Module), IP Multimedia Service Identity Module (ISIM, IP MultimediaService Identity Module), CDMA2000 Subscriber Identity Module (CSIM, CDMA2000 Subscriber Identity Module), etc. Of course, UICC cards can also run other applications, such as: electronic wallet, electronic cash, subway, bus, etc. In addition, one UICC card can carry multiple USIM, ISIM, CSIM and other applications at the same time. Such a UICC card can be applied to a variety of termi...
