Abstract
The invention discloses a single subscriber identity module (SIM) card with multiple central processing unit (CPU) cores. A subscriber sends an instruction required to be executed to a master control module through a mobile terminal; the master control module judges which CPU core is required to be called by the received instruction according to information carried by a message; and after the judgment is finished, the instruction is sent to the CPU core required to be operated. The execution process of the instruction can not produce any influences on other CPU cores, and operations are finished only in the CPU cores with corresponding functions to return to the master control module. The single SIM card with the multiple CPU cores has the advantages of being fast in responding, simple in structure, low in costs, reliable in connection, difficult to break off and widely applicable to mobile communication terminals.
