Embodiment Construction

[0028] see figure 1 , the mobile payment system of the present invention includes a mobile terminal 1 and a large-capacity USIM card 2 connected to it through an IC-USB interface 4. The mobile terminal 1 has a built-in radio frequency terminal 3 for near field communication and a payment application program 5 . The near field communication radio frequency terminal 3 interacts with external communication and data through the radio frequency field, and the mobile terminal 1 and the large-capacity USIM card 2 are connected through the IC-USB interface 4 . Different CCID card slots are used to distinguish the application protocol data unit APDU of the interactive telecommunication service between the mobile terminal 1 and the large-capacity USIM card 2 and the application protocol data unit APDU of the payment service.

[0029] see figure 2 , each pin function of large-capacity USIM card 2 among the present invention is defined as:

[0030] C1: power supply;

[0031] C2: r...

Abstract

The invention relates to a mobile payment system based on a high-capacity USIM card and an implementation method of the mobile payment system, which relate to the technical field of mobile payment. The mobile payment system comprises a mobile terminal and a high-capacity USIM card attached to the mobile terminal, wherein a near field communication RF head and a payment application program are arranged inside the mobile terminal, the mobile terminal is connected with the high-capacity USIM card through an IC-USB interface, and the near field communication RF head performs communication and data interaction with the outside through an RF field. Compared with the prior art, the mobile terminal adopted by the mobile payment system is connected with the high-capacity USIM card through the IC-USB interface for transaction, the transaction process is convenient, and the efficiency of mobile payment can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile payment, in particular to a mobile payment system based on a large-capacity USIM card and an implementation method thereof. Background technique [0002] With the upgrading of market demand and the maturity of near field communication technology, mobile payment has been more and more widely used. Among the current technical specifications and solutions for mobile payment, the NFC (Near Field Communication, Near Field Communication Protocol) solution that connects the mobile phone and the SIM (Subscriber Identify Module) through SWP (Single Wire Protocol, single-wire protocol) is relatively Mature and high market share. [0003] However, even if the NFC solution is adopted, it is still difficult for ordinary users to avoid the trouble of changing both the mobile phone and the SIM, because this solution requires the use of a customized mobile phone integrated with CLF (Contactless Front, non-contact...
