Embodiment 1
[0027] figure 1 It shows a schematic structural diagram of a mobile terminal described in Embodiment 1 of the present invention.
[0028] see figure 1 As shown, the mobile terminal includes a global subscriber identification USIM card 10, the USIM card 10 is connected to a MCU 12, and the MCU 12 is connected to two standard communication modules: the first standard communication module 14 and the second standard communication module 16, the first standard communication module 14 and the second standard communication module. The communication modules 16 of the second standard are all connected to the host computer 19 through the USB hub 18 .
[0029] In this embodiment, the USIM card 10 is a third-generation mobile phone card, also called an upgraded SIM card; the first standard communication module 14 can be a TD-LTE chip, and the second standard communication module 16 can be a TD-SCDMA chip; For example, an MCU 12 is added between the communication modules of the two stand...
Embodiment 2
[0042] figure 2 A flow chart showing a method for scheduling a USIM card according to Embodiment 2 of the present invention.
[0043] see figure 2 As shown, the USIM card dispatching method is used for a mobile terminal at least including a communication module of the first standard and a communication module of the second standard, including:
[0044] S201: Receive read and write commands for the USIM card from the communication module of the first standard and the communication module of the second standard, and perform unified scheduling processing on the read and write commands.
[0045] In this embodiment, by uniformly receiving the read and write commands of the first standard communication module and the second communication standard module to the USIM card, and performing unified scheduling processing on the USIM read and write requirements of the first and second standard communication modules, to avoid Read and write failures caused by concurrent reads and writes...
Embodiment 3
[0047] In the third embodiment, an MCU is added to the communication module of the first standard, the module of the second communication standard and the USIM card to uniformly receive the read and write commands of the communication module of the first standard and the module of the second communication standard.
[0048] image 3 A flow chart showing a method for scheduling a USIM card according to Embodiment 3 of the present invention.
[0049] see image 3 As shown, the USIM card scheduling methods include:
[0050] Step 31: Power on and initialize the MCU;
[0051] Step 33: read the general information of the USIM card;
[0052] In this step, the MCU reads the general information of the USIM card and divides the information into two parts, among which the shared information part is read into the memory of the MCU for direct reading by chips of various communication modes.
[0053] Step 35: Wait for a read command or interrupt;
[0054] In this step, the MCU is in a ...
