Problems solved by technology

[0031] Therefore, the above-mentioned method of simultaneously processing AT commands or APDU commands cannot guarantee the complete execution process of AT commands or APDU commands. If it is actually applied to a mobile terminal, the processing of the application programs running in parallel in the mobile terminal will be in a chaotic state.

Embodiment 1

[0087] A structural block diagram of a communication control system between a mobile terminal and a SIM card provided in an embodiment of the present invention, as shown in Figure 4 As shown, it includes: an application function device 401 , a baseband communication function device 402 , and a SIM card 403 .

[0088] The baseband communication function device 402 is used for receiving and processing the AT command or the APDU command sent by the application program in the application function device 401, and interacts with the SIM card 403, and returns the SIM card response to the command to the application program in the application function device 401. data. The baseband communication function device 402 specifically processes the AT command or the APDU command as follows:

[0089] Wherein, the baseband communication functional device 402 includes: an input / output interface module 411 , a first SIM card control module 412 , a second SIM card control module 413 , a SIM card...

Embodiment 2

[0146] Such as Figure 7 As shown, a structural block diagram of a communication control system between a mobile terminal and a SIM card provided by an embodiment of the present invention includes: an application function device 701 , a baseband communication function device 702 , and a SIM card 703 .

[0147] The baseband communication function device 702 is used to receive and process the AT command or APDU command sent by the application program in the application function device 701, and interact with the SIM card 703, and return the SIM card to the command response to the application program in the application function device 701. data. The baseband communication function device 702 specifically processes the AT command or the APDU command as follows:

[0148] Wherein, the baseband communication functional device 702 includes: an input / output interface module 711 , a first SIM card control module 712 , a second SIM card control module 713 , and a SIM card interface modul...

Abstract

The invention relates to the field of communication, in particular to communication technology between a mobile terminal and an SIM card. The communication method between the mobile terminal and the SIM card comprises the following steps: stopping the processing of subsequent AT instructions after processing the current AT instruction or determining that no AT instruction is required to be processed currently when receiving a first instruction of an APDU instruction sequence; and sequentially processing various received instructions in the APDU instruction sequence, and continuing to process the subsequent AT instructions after processing a final instruction in the APDU instruction sequence. The invention also provides a communication device between the mobile terminal and the SIM card. Because the APDU instruction sequence is executed and processed after waiting for the completion of the processing of the current AT instruction and the processing of the AT instructions is stopped in the process of processing the APDU instruction sequence, the completeness of the process of processing the AT instructions or the APDU instruction sequence is guaranteed and the communication function between the mobile terminal and the SIM card is enhanced.

Description

technical field [0001] The invention relates to the communication field, in particular to the communication technology between a mobile terminal and a SIM card. Background technique [0002] A SIM (Subscriber Identity Module, Subscriber Identity Module) card is a smart card used in a mobile communication device (such as the most common handheld mobile terminal). It includes user identification information, such as the user's MSISDN (Mobile Station ISDN, mobile station ISDN) number. A user can simply change mobile terminals by moving a SIM card from one mobile terminal to another. [0003] The information in the SIM card is usually recorded into a file for preservation, and the mobile terminal transmits the information to the SIM card through the APDU (Application Protocol Data Unit) command defined by the International Organization for Standardization (ISO) / International Electrotechnical Commission (IEC) 7816 standard. Perform operations such as reading and saving informat...
