Embodiment Construction

[0009] This embodiment will be further described below in conjunction with the drawings.

[0010] Such as figure 1 As shown, the radio frequency SIM card 100 mainly includes a timer circuit 101 , a main control chip 102 , and a radio frequency data communication module 103 .

[0011] The main control chip 102 mainly has 3 functions as the CPU core of the radio frequency SIM card 100:

[0012] 1) Carrying the telecom COS, connected to the mobile phone terminal through the 7816 contacts of the radio frequency SIM card 100, supporting telecom applications.

[0013] 2) Connect with the radio frequency data communication module 103 through a general IO interface (such as SPI) to complete the operation of the radio frequency data communication module 103, such as initialization, controlling it to enter and exit the sleep state, receiving and sending radio frequency data, etc.

[0014] 3) It is connected with the timer circuit 101, has an external interrupt wake-up function, and ou...

Abstract

The invention relates to a device and a method for regularly awakening a radio frequency subscriber identity module (SIM) card. The device mainly comprises a main control chip, a timer circuit and a radio frequency data communication module. After a system is initialized or ready for radio frequency data communication, the main control chip and the radio frequency data communication module are in dormancy states, the timer circuit produces a regular awakening signal for awakening the main control chip; the main control chip controls the timer circuit to be in a non-working state and awakens the radio frequency data communication module; if radio frequency data exist, data communication is carried out; if the radio frequency data do not exist, the radio frequency data communication module is controlled to be in the dormancy state, and the timer circuit is started; and moreover, the timer circuit enters the dormancy state and waits for awakening at the next time.

Description

technical field [0001] The invention relates to the field of radio frequency communication, in particular to the field of application of radio frequency smart cards based on mobile payment. Background technique [0002] With the popularization and development of mobile communication equipment, mobile phones have become an indispensable daily article in people's communication, and have been used more and more. The development of the mobile phone has also developed from the original simple communication tool to the information communication function of sending and receiving short messages, and then to the ability to download pictures, take pictures and other multimedia functions, and then to be able to surf the Internet, send and receive emails, and perform banking, securities and other business transactions. Mobile information terminals in the true sense make people more and more inseparable from mobile phones. In particular, the research on the use of mobile phones in mobil...
