Problems solved by technology

Although this technology realizes the functions in the financial field on the SIM chip, it still has the following shortcomings: First, before calling the extension function of the corresponding specification, it is necessary to pre-judge whether the received data type supports traditional GSM ( Global System for Mobile Communications) or PBOC2.0 financial field applications, so it does not have good compatibility; secondly, this technology has the problem of incompatibility for different external devices in practical applications. For different types and models of external devices , professional and technical personnel are still required to develop and provide specific and targeted technologies, making this technology unable to be widely used

Embodiment 1

[0052] Example 1 as figure 1 with figure 2 shown, including the following steps:

[0053]Step 1: Connect the data communication interface of the mobile terminal with the C6 pin on the SIM chip.

[0054] Step 2: The NFC module in the mobile terminal receives the PBOC data command sent by the POS machine of the external terminal through a non-contact method according to the 14443 wireless communication protocol.

[0055] Step 3: The SIM chip receives data through the two-way 7816 standard data transmission method or the SWP data transmission method.

[0056] The described two-way 7816 standard data transmission method, the specific steps include:

[0057] ①The SIM chip enters the entry state;

[0058] ②SIM chip for entry operation;

[0059] ③ The PBOC logic processing module of the SIM chip receives PBOC data instructions.

[0060] The entry state: after the SIM chip receives a legal APDUH instruction sent according to the T=0 protocol, the mobile terminal sends a PBOC da...

Embodiment 2

[0078] Example 2 as image 3 As shown, the SIM chip receives the PBOC data instruction through the two-way 7816 standard data transmission method and executes the circle withdrawal transaction operation.

[0079] According to the 14443 wireless communication protocol, the NFC module in the mobile terminal receives the data command from the POS machine of the external terminal through a non-contact method, and the mobile terminal sends PBOC data to the SIM chip through the two-way 7816 standard data transmission method. , the SIM chip enters the entry state to receive the initializing command data of the ring lifting, and the data is transmitted in a block structure. After completing the initialization command, the SIM chip operating system enters the exit program and returns to the previous GSM application state.

[0080] The SIM chip enters the entry state, and the process of receiving and processing the data block of the initializing command is as follows:

[0081] a) Chec...

Embodiment 3

[0103] Example 3 as Figure 4 As shown, the SIM chip receives the PBOC data instruction through the SWP data transmission method and executes the loading transaction operation.

[0104] According to the 14443 wireless communication protocol, the NFC module in the mobile terminal receives the data command from the POS machine of the external terminal in a non-contact way, and the mobile terminal sends PBOC data to the SIM chip through the SWP data transmission mode, that is, sends the PBOC data to the SIM chip through the C6 pin of the SIM chip. send data. The process of SIM chip receiving and processing load initialization is as follows:

[0105] a) Check whether the key index number provided in the command is supported: if it is not supported, return the status code '9403' indicating that the key index is not supported, but do not return any other data, and the command processing ends;

[0106] b) The PBOC logic module will generate a pseudo-random number, a process key and...

Abstract

The invention relates to a multi-terminal information receiving and processing method for a self-adapting SIM chip operating system, which pertains to the technical field of mobile communication. The method comprises the steps that: first, a data communication interface of a mobile terminal is connected with a C6 pin on an SIM chip; then an NFC module in the mobile terminal receives a PBOC data command sent by an external terminal POS machine in a non-access manner according to14443 Wireless Application Protocol; the SIM chip receives data in a bidirectional 7816 standard data transmission way or in an SWP data transmission way; in the 7816 standard data transmission way, after receiving PBOC data, an SIM card enters an approach operation; a PBOC logic processing module processes credit for unload operation and credit for load operation corresponding to the PBOC data command and enters a withdrawal operation and backs to a GSM operation mode. In the SWP data transmission way, the SIM chip receives the data by the C6 pin and executes relevant operations; after operations are finished, the SIM chip is in the GSM operation mode; the two transmission ways are complementary and mutually independent and can be compatible with various mobile terminals and the hardware of the SIM chip.

Description

technical field [0001] The invention relates to a method in the technical field of mobile communication, in particular to a method for receiving and processing multi-terminal information by an adaptive SIM (Subscriber Identity Authentication Module) chip operating system. Background technique [0002] Existing electronic cards for payment through online electronic banking include two application types, electronic wallet and electronic passbook, and the two application types correspond to different transaction processes and transaction instructions respectively. Among them, there are two concepts of electronic wallet: one is pure software, which is mainly used for online consumption and account management. This kind of software is usually connected with bank account or bank card account; Value card, the cardholder deposits a certain amount of money in the card in advance, and the transaction amount is directly deducted from the stored value account during the transaction. Cu...
