Abstract

The invention relates to an intelligent card timing method and system, and belongs to the technical field of intelligent cards. The intelligent card comprises an application layer, Operating system layer and hardware layer, the application layer comprises a plurality of application programs; wherein the operating system layer comprises an interface module and a timing management module, the hardware layer comprises a plurality of internal physical timers, an application program interacts with the timing management module through the interface module, the timing management module controls timing through a logic timer, and the logic timer is associated with the internal physical timers or an analog timer. The timing method comprises the following steps that a timer operation request of an application program is received, a corresponding logic timer is created according to the timer operation request, and the timer operation request comprises the type of the timer and a corresponding operation instruction; Correspondingly associating the created logic timer with an internal physical timer or an analog timer; And controlling the internal physical timer or the analog timer to perform related timing operation through the logic timer according to the operation instruction.

Description

technical field [0001] The invention relates to a smart card timing method and system, belonging to the technical field of smart cards. Background technique [0002] A smart chip such as a smart card is a secure hardware with arithmetic logic, storage area and communication interface, on which software runs to achieve specific functions, similar to a simplified version of a computer. The software running on the smart card is generally written and implemented by assembly language, C language, JAVA language, etc. [0003] In some application scenarios, smart cards often need to perform timing actions, that is, timing a specific period of time from a certain point in time, and then perform certain business processing. This is a very basic application scenario. As smart cards become more powerful and proactive, this scenario will become more frequent. [0004] There are two existing methods for SIM cards: [0005] First, the standards of GSM and 3GPP require that the mobile p...
