For example, NFC communication is used as an example:

Referring to FIG. 1 , which is a schematic flowchart of an embodiment of a NFC switching near field communication method provided by the present invention, the method includes:

Step S100: The mobile terminal acquires a current working state of the mobile terminal.

Specifically, the working state in the embodiment of the present invention is application information triggered by the mobile terminal itself and/or data collected by the sensor; the application program triggered by the mobile terminal may include an NFC payment program, an NFC home appliance control program, or an NFC file transmission program. The data collected by the sensor may include data collected by sensors collected by at least one sensor such as a gyroscope, an accelerometer, a displacement sensor, a compass, a proximity light/light sensor, a camera, etc., such as physical attitude information and movement trend information of the mobile terminal. The physical posture is a tilting posture such as a horizontally upward direction of the mobile terminal, a horizontally facing downward, a vertical erect, an inverted erect, a front positive tilt, or a left tilt. The mobile trend is a mobile terminal motion trajectory and a motion trend. . Step S102: The mobile terminal determines NFC communication indication information of the mobile terminal according to the working state; the NFC communication indication information is used to indicate an NFC antenna for performing NFC communication;

Step S104: The mobile terminal selects at least one NFC antenna from the plurality of NFC antennas to perform NFC communication with the external device according to the determined NFC communication indication information.

Specifically, the mobile terminal is provided with at least two NFC antennas for non-contact communication with an external device. For example, each of the front and the back of the mobile terminal is provided with an antenna, and then the NFC communication indication information determined by the mobile terminal indicates the back of the mobile terminal. When the NFC antenna performs non-contact communication with an external device, the mobile terminal selects the NFC antenna on the back side for NFC communication; when the determined NFC communication indication information indicates that the antenna on the front side of the mobile terminal performs contactless communication with the external device, the front NFC is selected. The antenna performs NFC communication.

The NFC communication indication information of the mobile terminal is determined according to the current working state of the mobile terminal, and at least one NFC antenna is selected from the plurality of NFC antennas to perform NFC communication with the external device, thereby solving the mobile terminal in the prior art. The problem must be carried out within the specified structural plane and angle range, which greatly improves the success rate of NFC communication, and enables the user to perform non-contact communication through any handheld mode or any angle, thereby improving the NFC communication function and NFC communication efficiency of the mobile terminal. The power consumption of the mobile device's main processor can be reduced by triggering a low-power processor to control the contactless communication of the antenna.

Further, a schematic flowchart of another embodiment of a plurality of NFC-switched near field communication methods provided by the present invention, as shown in FIG. 2, when the working state is application information triggered by the mobile terminal, the method Includes:

Step S200: The mobile terminal acquires a current working state of the mobile terminal.

Step S202: The mobile terminal determines an NFC working mode according to an application triggered by the mobile terminal.

Specifically, the NFC working mode can be divided into a card mode, a read/write mode, and a P2P mode, wherein the card mode refers to the NFC communication device being simulated into a card, and after the card is downloaded and applied, the card can be consumed. The read/write mode means that the NFC communication device can read the card, such as reading the balance on the bank card, the balance of the bus card, etc., and can also be used as a POS machine. P2P mode means that two NFC communication devices can exchange data. Then, according to the application triggered by the mobile terminal, the NFC working mode can be determined. For example, if the mobile terminal triggers the NFC payment application, it can be determined that the working mode is the card mode; When the NFC appliance control application is triggered, the working mode can be determined to be the read/write mode; if the mobile terminal triggers the NFC file transfer application, the working mode can be determined to be the P2P mode, and so on.

Step S204: The mobile terminal instructs the NFC antenna that performs NFC communication according to the determined NFC working mode.

Specifically, the default setting may be used to indicate that a specific NFC working mode corresponds to an NFC antenna that the user prefers to use. For example, when the NFC working mode is the card mode, the user may prefer NFC communication on the back or front side of the handheld mobile terminal. , then it can be instructed to use the back NFC antenna of the mobile terminal or the front NFC antenna for NFC communication; and when the NFC working mode is the read/write mode, the user tends to use the front side, the left side or the right side for NFC communication, then Instructing to use the front side NFC antenna of the mobile terminal, the left side NFC antenna, or the right side NFC antenna for NFC communication;

Step S206: The mobile terminal selects at least one NFC antenna from the plurality of NFC antennas to perform NFC communication with the external device according to the determined NFC communication indication information.

Specifically, when there is only one NFC antenna indicating the NFC communication, the NFC antenna is directly selected to perform NFC communication with the external device; when the NFC antenna indicating the NFC communication is at least two, the NFC antenna can be statistically compared. Using the statistical data obtained by the usage habit, the at least two NFC antennas indicated by the NFC communication indication information are prioritized; then the NFC antenna with a high priority is selected to perform NFC communication with the external device. In detail, it is assumed that an NFC antenna is provided on the front, the back, and the front side of the mobile terminal, and the two NFC antennas provided may be prioritized according to the user's usage habits, for example, when the NFC working mode is When the card mode corresponds to the NFC communication using the back NFC antenna or the front NFC antenna of the mobile terminal, the user can be more accustomed to using the front NFC antenna for contactless communication by counting the usage habits of the current user, and then the front NFC can be set. The priority of the antenna is higher than that of the back NFC antenna. For example, when the NFC working mode is the read/write mode, the mobile terminal can be used to count the usage habits of the current user, and the user is more accustomed to using the NFC antenna on the front side. Non-contact communication, then the front side of the NFC has the highest priority.

It can be understood that the user's usage habits may be a user's pre-customized tendency to use according to their own needs, or the system may obtain statistical data obtained by using the user's usage habit information for a period of time.

Various tilting postures such as erecting, front positive tilting, or left tilting, etc., the moving tendency is the moving trajectory of the mobile terminal and the moving tendency.

Step S302: The mobile terminal indicates, according to the physical posture and the mobile trend, an NFC antenna that performs NFC communication;

Specifically, the NFC antenna is disposed on both the front and the back of the mobile terminal, and then, if the mobile terminal is currently moving face down, the NFC communication may be indicated by using the front NFC antenna of the mobile terminal; The mobile terminal is tilted forward, and when the back is moved forward, the back NFC antenna of the mobile terminal can be instructed to perform NFC communication.

If the left side of the current mobile terminal is closest to the external device, the left side of the mobile terminal may be indicated. The NFC antenna performs NFC communication; if the back side of the mobile terminal is facing the external device, the NFC communication using the back NFC antenna of the mobile terminal can be instructed.
