Near Field Communication (NFC), also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission (within ten centimeters) between electronic devices to exchange data . This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID. It was first developed by Sony and Philips respectively, and is mainly used to provide M2M (Machine to Machine) communication in handheld devices such as mobile phones. Due to the natural security of near-field communication, NFC technology is considered to have great application prospects in fields such as mobile payment.

As shown in Figure 1, it is the implementation process of reporting the NFC transaction event of the mobile terminal in the prior art, and its steps are as follows:

(1) NFC mobile phone terminal conducts NFC contactless transactions in the NFC acceptance environment;

(2) The security module (Security element) in the NFC SIM perceives the NFC contactless transaction event, and after completing the transaction processing, reports the NFC contactless transaction event to the CLF module of the NFC terminal;

(3) CLF transparently transmits the event to the NFC protocol stack in the NFC mobile terminal;

(4) The NFC protocol stack reports the event to the Android operating system;

(5) The operating system (such as Android) broadcasts the event to all mobile applications.

However, the CLF in the existing NFC terminal hardware does not have the function of judging the relationship between the NFC event and the SIM card, so for a mobile terminal with multiple SIM cards, the security module in it reports the NFC contactless transaction event to the CLF module Finally, the CLF module cannot determine which SIM card the NFC contactless transaction event corresponds to; and, after being transparently transmitted to the operating system through the NFC protocol stack, the event will be pushed to all NFC-related applications, which cannot effectively guarantee Transaction security.

Detailed ways

Aiming at the problem in the prior art that effective NFC event reporting cannot be carried out for multi-SIM mobile terminals, the present invention proposes a method for reporting NFC events of mobile terminals. Through transformation, the mobile terminal is added with an event selection function, thereby supporting dual-card mobile phone NFC For the problem of event conflicts, at the same time, an NFC event uploading event manager is added on the upper layer of the NFC protocol stack, which is responsible for the registration and management of sensitive events for all terminal applications. After the NFC event is sent, it is responsible for event screening and screening. Specifically, as an example, a schematic diagram of an improved mobile terminal may be shown in FIG. 2 .

Based on the above explanation, the method proposed by the present invention is applied in the mobile terminal provided with NFC SIM card, NFC protocol stack, event manager and CLF module, and its flow process as shown in Figure 3, comprises the following steps:

S301. The CLF module receives an NFC event.

Specifically, the present invention sets a security module in the NFC SIM card of the mobile terminal, and the security module can perceive the NFC event of the NFC SIM card, and after confirming that the NFC event is completed, the NFC event is sent to the CLF module.

In addition, since the ultimate goal of the present invention is to report the NFC event to the corresponding target application (the target application can be an APP adapted to the mobile terminal), before this step, the operating system receives the NFC event from the mobile terminal A registration request of the application, the registration request carrying the application and the identification of the corresponding NFC SIM card;

The operating system generates the registration information according to the identification, registers and declares the application;

The operating system sends the registration information and the identifier to the event manager.

In the schematic diagram of the NFC transaction event sending implementation scheme shown in Figure 4, the NFC mobile phone terminal performs NFC contactless transactions in the NFC acceptance environment, and the security module (Security element) in the NFC SIM senses the NFC contactless transaction event and completes After the transaction is processed, the NFC contactless transaction event is sent to the CLF module of the NFC terminal. When all applications are registered in the operating system, the operating system needs to notify the event manager, including the sensitive event type, sensitive transaction time and priority sent by the event. The event types include but are not limited to: whether the transaction consumption needs to be sensitive, whether the transaction record query needs to be sensitive, whether the recharge transaction needs to be sensitive, etc., and the transaction time refers to the time period when the transaction information is reported when the event manager is registered (such as 8:00-17:00), outside this time period, the event manager will not send transaction events, and the priority refers to the order of priority reporting when the transaction event queue is sent.

S302. The CLF module determines the occurrence time and the NFC SIM card corresponding to the NFC event, and generates event information corresponding to the NFC event according to the occurrence time and the identifier of the NFC SIM card.

In the case of only one NFC SIM card in the mobile terminal, the CLF module can directly use the NFC SIM card as the NFC SIM card corresponding to the NFC event. But when multiple NFC SIM cards are included in the mobile terminal, the CLF module will set the NFC SIM card of the security module as the NFC SIM card corresponding to the NFC event by identifying the security module sending the NFC event .

Specifically, when the CLF module receives a transaction event, it needs to put a transaction stamp on the transaction event. The transaction stamp includes the SIM card where the transaction occurred and the time when the transaction occurred, and then the CLF module sends it to the NFC protocol stack.

S303. The CLF module transparently transmits the NFC event and the event information to the NFC protocol stack.

S304. The NFC protocol stack sends the NFC event and the event information to the event manager.

S305. The event manager determines the reporting information of the NFC event according to the event information, and sends the NFC event and the reporting information to the operating system of the mobile terminal.

In this step, the event manager first takes the application corresponding to the identifier in the event information among the registered applications as the reporting target application; then obtains the registration information of the reporting target application, and according to the registration information and The event information determines the priority identification of the NFC event and whether it needs to be reported immediately;

If yes, the event manager generates the reporting information according to the priority identifier, the identifier of the reporting destination application, the event information, and an indication of immediate reporting;

If not, the event manager generates the reporting information according to the priority identifier, the identifier of the reporting destination application, the event information, and an indication of non-immediate reporting.

In the specific implementation process, the present invention further divides the registration information into sensitive event types and reporting time periods, and the event manager determines the priority identification of the NFC event and whether it needs to be reported immediately in the following manner:

(1) If the event manager identifies the NFC event as the sensitive event type, the event manager sets a high priority flag for the NFC event;

(2) If the event manager recognizes that the NFC event is not the sensitive event type, the event manager sets a low priority flag for the NFC event;

(3) If the event manager judges that the occurrence time in the event information is within the reporting time period, the event manager determines that it needs to be reported immediately;

(4) If the event manager judges that the occurrence time in the event information is not within the reporting time period, the event manager determines that it is not necessary to report immediately.

S306. The operating system reports the NFC event to the target application according to the reporting information.

Based on the reporting information generated by the event manager in S305, the operating system first adds the NFC event corresponding to the reporting information carrying the immediate reporting instruction to the reporting queue, and then reports the NFC event with a high priority identifier in the reporting queue to the The stated purpose applies.

In a specific implementation solution, the event manager adds the priority, the application package name and class name corresponding to the event to the timestamp of the transaction time (used for the operating system to locate the corresponding application), and then sends it to the operating system to operate The system sends the transaction stamp information of the event to the corresponding application. The final reported event transaction stamp includes the following information:

Event type ID, event time, priority, SIM card triggered by the event, package name of the application corresponding to the event, and class name of the application corresponding to the event.
