101. and when the mobile terminal detects that the near field communication equipment is in a communication range, establishing near field communication connection with the near field communication equipment by adopting preset near field communication parameters.

And the mobile terminal is in near field communication connection with the near field communication equipment through preset near field communication parameters.
102. And judging whether the near field communication connection is successfully established.
Because the currently used near field communication parameters are not necessarily applicable to all near field communication devices, if the near field communication devices are non-standard devices, the mobile terminal may be unsuccessfully connected with the near field communication devices, and therefore, the problem can be solved simply and efficiently by judging whether the near field communication connection is established successfully.

For example, the preset near field communication parameters include N, a near field communication parameter a is currently adopted, near field communication connection is established again with the near field communication device by changing to the near field communication parameter B, if the near field communication connection is still not established successfully, the near field communication parameter B is changed to the near field communication parameter C to perform communication connection again, and the parameters are changed in sequence until the parameters are successfully changed, so that the success rate of connection between the mobile terminal and the near field communication device can be improved.

The radio frequency parameters are stored in the mobile terminal in advance, and the success rate of the connection between the mobile terminal and the near field communication equipment can be improved by replacing the near field communication parameters until the near field communication connection between the mobile terminal and the near field communication equipment is successful.
It can be understood that an embodiment of the present application further provides a near field communication method, please refer to fig. 2, where fig. 2 is a second flowchart schematic diagram of the near field communication method provided in the embodiment of the present application, where the near field communication method includes:
201. and when the mobile terminal detects that the near field communication equipment is in a communication range, establishing near field communication connection with the near field communication equipment by adopting preset near field communication parameters.
The near field communication device may be a card reader, or may be a card, such as a bus card or a subway card. When the near field communication device is a card reader, the mobile terminal may be an analog card, for example, the mobile terminal may be used for swiping a gate, a bus, a subway, or the like, and when the near field communication device is a card, the mobile terminal may also have a function of a card reader, for example, recharging a bus card, or the like.
The communication range may be a distance that the mobile terminal and the near field communication device may allow communication connection, that is, a distance between the near field communication device and the mobile terminal, and the distance may be 0 to 3 centimeters, that is, the communication range is 0 to 3 centimeters.
The preset near field communication parameters are preset in the mobile terminal, and the preset near field communication parameters are multiple, wherein the preset near field communication parameters can correspond to the types of the near field communication equipment, and each near field communication parameter corresponds to one type of near field communication equipment. And the mobile terminal is in near field communication connection with the near field communication equipment through preset near field communication parameters.
202. And when the mobile terminal works in a card simulation mode, receiving a first near field communication connection request sent by the near field communication equipment.
The card simulation mode refers to a function of the mobile terminal similar to a card, for example, the mobile terminal can be used for releasing access control, or the mobile terminal can be used for a subway station and a user can enter the station by swiping the card through the mobile terminal.
When the mobile terminal is used for simulating the access control card, the access control card is close to the back of the mobile terminal, and the mobile terminal generates the access control simulation card according to the data of the access control card by reading the data of the access control card.
Wherein, the generation of the entrance guard simulation card according to the data of the entrance guard card can be understood as that a card is generated according to the data of the entrance guard card after the function of the mobile wallet reads the data of the entrance guard card, the card can be understood as an entrance guard simulation card, all data of the entrance guard card are stored in the card, and the entrance guard simulation card in the mobile phone can be identified with the card reader, so that the entrance guard card can be prevented from being carried, and convenience is brought to users for going out.
When the mobile terminal is used as an analog card, the card reader sends a first near field communication connection request when the analog card approaches the card reader, and the analog card receives the first near field communication connection request.
The first near field communication connection request may be an instruction for requesting a communication connection, for example, the card reader sends a near field communication connection request instruction to the analog card.
203. And sending first data authentication information of the mobile terminal to the near field communication equipment according to the first near field communication connection request.
And when the mobile terminal receives the first near field communication connection request, sending data authentication information of the mobile terminal to the near field communication device, where the first data authentication information of the mobile terminal may be key information, and the key information may include a near field communication protocol, a near field communication connection password, identity information of the mobile terminal, and the like.
204. And judging whether the mobile terminal receives feedback information sent by the near field communication equipment within a first preset time length, wherein the feedback information is the feedback information sent by the near field communication equipment according to the first data authentication information.
The card reader receives first data authentication information sent by the mobile terminal, the card reader judges whether the first data authentication information of the mobile terminal is valid or not according to the first data authentication information of the mobile terminal, if the first data authentication information of the mobile terminal is matched with the data information of the card reader, the first data authentication information of the mobile terminal is valid, the card reader sends feedback information to the mobile terminal, if the first data authentication information of the mobile terminal is not matched with the data information of the card reader, the first data authentication information of the mobile terminal is invalid, and the card reader does not send feedback information to the mobile terminal.
The first preset time is preset in the mobile terminal in advance, so that the mobile terminal can make an accurate and quick judgment, and the first preset time may be 5-10 seconds, for example.
205. And when the mobile terminal does not receive the feedback information sent by the near field communication equipment within the first preset time length, judging that the near field communication connection is not established successfully.
Because the first data authentication information sent by the mobile terminal is invalid, the card reader cannot send feedback information to the mobile terminal, so that the mobile terminal cannot receive the feedback information sent by the near field communication equipment within a first preset time length, and the near field communication connection between the mobile terminal and the card reader cannot be successful.
206. And if the near field communication connection is not successfully established, acquiring the communication frequency of each near field communication parameter in the historical near field communication record.
The historical communication record refers to a record of communication with the near field communication device by using the mobile terminal, wherein the communication frequency refers to the number of times of communication with the near field communication device by using the near field communication parameter, for example, the number of times of communication with the card reader by using the near field communication parameter a is 5, that is, the communication frequency is 5, the number of times of communication with the card reader by using the near field communication parameter B is 8, that is, the communication frequency is 8, and the number of times of communication with the card reader by using the near field communication parameter C is 12, that is, the communication frequency is 12.
207. And selecting the near field communication parameter with the maximum communication frequency to establish the near field communication connection with the near field communication equipment again according to the communication frequency of each near field communication parameter.
The success rate of near field communication between the near field communication parameters and the near field communication equipment is higher as the communication frequency of the near field communication parameters is higher, so that the success rate of establishing near field communication connection with the near field communication equipment again by selecting the near field communication parameters with the maximum communication frequency is higher.
It is understood that, in order to more conveniently obtain the near field communication parameter with the largest communication frequency, the communication frequencies of each near field communication parameter may be ordered from large to small or from small to large.
208. And if the near field communication connection is successfully established, detecting whether the near field communication connection is disconnected within a second preset time length.
Due to the fact that in practical application, although the near field communication connection between the mobile terminal and the near field communication device is successfully established, the access control is not released, or the card is not charged successfully, and the reason that the access control is not contacted or the card is not charged successfully is that the communication connection between the mobile device and the near field communication device is disconnected in the card swiping process.
The second preset duration is a parameter set in advance, which is convenient for the mobile terminal to make an accurate judgment quickly, for example, the second preset duration may be 1 to 3 seconds.
By detecting whether the near field communication connection between the mobile terminal and the near field communication equipment is disconnected within a preset time, the successful connection probability between the mobile terminal and the near field communication equipment can be improved.
209. And if the near field communication connection is disconnected within the second preset time, detecting whether the near field communication equipment is in the communication range again.
For example, when the near field communication is just established successfully, the mobile phone receives a voice message, and the user may move the mobile phone away from the card reader to read the voice message, so that the near field communication may be disconnected when the mobile phone is not in the communication range.
210. And if the near field communication equipment is in the communication range, establishing the near field communication connection with the near field communication equipment again by using the preset near field communication parameters which successfully establish the near field communication connection with the near field communication equipment.
If it is detected that the nfc link is disconnected within the second preset duration, and the nfc device is also within the communication range, which may be signal instability, an attempt may be made to establish the nfc link with the nfc device again using the preset nfc parameters that successfully establish the nfc link with the nfc device.
It can be understood that, if it is detected that the near field communication connection is disconnected within the second preset time period, and the near field communication device is also within the communication range, which may be signal instability or signal strength too poor, the signal strength of the near field communication parameter may be increased by increasing the transmission power of the preset near field communication parameter, so as to more stably establish a communication connection between the mobile terminal and the near field communication device. And the preset near field communication parameters are preset near field communication parameters for successfully establishing near field communication connection with the near field communication equipment.
According to the near field communication method provided by the embodiment of the application, when the mobile terminal detects that the near field communication equipment is in a communication range, a near field communication connection is established with the near field communication equipment by adopting preset near field communication parameters; when the mobile terminal is in a card simulation mode; after the mobile terminal sends the data authentication information, whether the mobile terminal receives feedback information sent by the near field communication equipment to judge whether the near field communication is established successfully or not is judged, if the near field communication connection is not established successfully, the near field communication parameters with the highest communication frequency are selected to establish the near field communication connection with the near field communication equipment again until the near field communication connection is established successfully. The success rate of near field communication between the near field communication parameters and the near field communication equipment is higher as the communication frequency of the near field communication parameters is higher, so that the success rate of establishing near field communication connection with the near field communication equipment again by selecting the near field communication parameters with the maximum communication frequency is higher.
Fig. 3 shows a schematic view of a third flow structure of the near field communication method according to the embodiment of the present application. The near field communication method further includes:
301. and when the mobile terminal detects that the near field communication equipment is in a communication range, establishing near field communication connection with the near field communication equipment by adopting preset near field communication parameters.
The near field communication device may be a card reader, or may be a card, for example, a public transportation card, a subway card, or the like. When the near field communication device is a card reader, the mobile terminal may be an analog card, for example, the mobile terminal may be used for swiping a gate, a bus, a subway, or the like, and when the near field communication device is a card, the mobile terminal may also have a function of a card reader, for example, recharging a bus card, or the like.
The communication range may be a distance that the mobile terminal and the near field communication device may allow communication connection, that is, a distance between the near field communication device and the mobile terminal, and the distance may be 0 to 3 centimeters, that is, the communication range is 0 to 3 centimeters.
The preset near field communication parameters are preset in the mobile terminal, and the preset near field communication parameters are multiple, wherein the preset near field communication parameters can correspond to the types of the near field communication equipment, and each near field communication parameter corresponds to one type of near field communication equipment. And the mobile terminal is in near field communication connection with the near field communication equipment through preset near field communication parameters.
302. And when the mobile terminal works in a card reader mode, sending a second near field communication connection request to the near field communication equipment.
The card reader mode means that the mobile phone can be equivalent to a card reader, and data information in the card can be read through the mobile phone. When the mobile terminal is used as a card reader, the near field communication device may be a card, for example, the near field communication device is a bus card or a subway card, and the mobile terminal may recharge the bus card or the subway card.
And if the second near field communication connection request is that the near field communication equipment approaches the mobile phone, the mobile phone sends a communication connection request instruction to the near field communication equipment, and the near field communication equipment performs corresponding operation according to the communication connection request instruction.
303. And receiving second data authentication information returned by the near field communication equipment according to the second near field communication connection request.
And when the near field communication equipment receives the second near field communication connection request, sending second data authentication information of the near field communication equipment to the mobile terminal.
The second data authentication information may be key information, and the key information may include a near field communication connection password, identity information of the near field communication device, and the like.
304. And judging whether the second data authentication information of the near field communication equipment is valid.
After receiving the second data authentication information, the mobile terminal determines whether the second data authentication information of the near field communication device is valid according to the second data authentication information, for example, whether the near field communication connection password according to the second data authentication information matches with the communication protocol of the mobile terminal, if so, it indicates that the second data authentication information of the near field communication device is valid, and if not, the second data authentication information of the near field communication device is invalid.
305. And if the second data authentication information is invalid, judging that the near field communication connection is not successfully established.
And if the second data authentication information is invalid, the near field communication password of the near field communication equipment is not matched with the near field communication protocol of the mobile terminal, and the near field communication connection between the mobile terminal and the near field communication equipment cannot be successfully established.
306. And acquiring the frequency of the current preset near field communication parameters.
The current preset near field communication parameters may be understood as near field communication parameters adopted when the mobile terminal is communicating with the near field communication device, that is, near field communication parameters adopted before the near field communication parameters are replaced when the mobile terminal is not successfully in communication with the near field communication device, for example, the mobile phone adopts a near field communication parameter a to try to perform near field communication connection with the card reader, and at this time, the a near field communication parameters are the current preset near field communication parameters.
The frequency of the near field communication parameter is a signal frequency used when the mobile phone performs near field communication with the card reader, and the frequency may be 13.56MHz, for example.
307. And adjusting the frequency of the current preset near field communication parameters according to preset parameters, and selecting the adjusted current preset near field parameters to establish near field communication connection with the near field communication equipment again.
The preset parameter may be understood as the amplitude of the frequency of the current preset near field communication parameter, which may be 0.3, for example, each time the frequency of the current preset near field communication parameter is adjusted up or down by 0.3MHz. For example, the frequency of the current preset near field communication parameters is 13.56MHz, and the frequency of the current preset near field communication parameters may be 13.26MHz or 13.86MHz each time the adjustment is made.
It can be understood that, replacing the preset near field communication parameters to establish a near field communication connection with the near field communication device again may further include:
acquiring signal intensity of all preset near field communication parameters;
and selecting the preset near field parameter with the maximum signal intensity to establish the near field communication connection with the near field communication equipment again according to the signal intensities of all the preset near field communication parameters.
In practical application, whether the mobile terminal and the near field communication device successfully establish the near field communication connection is related to the signal strength of the near field radio frequency parameter, and if the signal strength of the near field radio frequency parameter is too weak, the mobile terminal and the near field communication device cannot successfully establish the near field communication connection.
Therefore, in order to further improve the probability of successfully establishing the near field communication connection between the mobile terminal and the near field communication device, the preset near field parameter with the maximum signal strength is selected to establish the near field communication connection with the near field communication device again by acquiring the signal strengths of all the preset near field communication parameters.
It can be understood that, in order to further improve the probability that the mobile terminal and the near field communication device successfully establish the near field communication connection, the communication frequency and the signal strength of each preset near field communication parameter may also be obtained at the same time, and the near field communication parameter with the largest communication frequency and signal strength is selected to establish the near field communication connection with the near field communication device again. And when the signal intensity is maximum and the communication frequency is not maximum, selecting the near field communication parameter with the maximum communication frequency to establish the near field communication connection with the near field communication equipment again.
308. And if the near field communication connection is successfully established, detecting whether the near field communication connection is disconnected within a second preset time length.
Due to the fact that in practical application, although the near field communication connection between the mobile terminal and the near field communication device is successfully established, the access control is not released, or the card is not charged successfully, and the reason that the access control is not contacted or the card is not charged successfully is that the communication connection between the mobile device and the near field communication device is disconnected in the card swiping process.
The second preset duration is a parameter set in advance, which is convenient for the mobile terminal to make an accurate judgment quickly, for example, the second preset duration may be 1 to 3 seconds.
By detecting whether the mobile terminal and the near field communication equipment are disconnected within the preset time, the probability of successful connection between the mobile terminal and the near field communication equipment can be improved.
309. And if the near field communication connection is disconnected within the second preset time length, detecting whether the near field communication equipment is in a communication range again.
For example, when the near field communication is just established successfully, the mobile phone receives a voice message, and the user may move the mobile phone away from the card reader to read the voice message, so that the near field communication may be disconnected when the mobile phone is not in the communication range.
310. And if the near field communication equipment is in the communication range, establishing the near field communication connection with the near field communication equipment again by using the preset near field communication parameters for successfully establishing the near field communication connection with the near field communication equipment.
If it is detected that the nfc link is disconnected within the second preset duration, and the nfc device is also within the communication range, which may be signal instability, an attempt may be made to establish the nfc link with the nfc device again using the preset nfc parameters that successfully establish the nfc link with the nfc device.
It can be understood that, if it is detected that the near field communication connection is disconnected within the second preset time period, and the near field communication device is also within the communication range, which may be signal instability or signal strength too poor, the signal strength of the near field communication parameter may be increased by increasing the transmission power of the preset near field communication parameter, so as to more stably establish a communication connection between the mobile terminal and the near field communication device. And the preset near field communication parameters are preset near field communication parameters for successfully establishing near field communication connection with the near field communication equipment.
According to the near field communication method provided by the embodiment of the application, when the mobile terminal detects that the near field communication equipment is in a communication range, a near field communication connection is established with the near field communication equipment by adopting a preset near field communication parameter; when the mobile terminal is in a card reader mode; after the mobile terminal receives the data authentication information sent by the near field communication equipment, whether the near field communication is established successfully is judged by judging whether the data authentication information of the near field communication equipment is valid, if the near field communication connection is not established successfully, the frequency of the current near field communication parameters is adjusted according to preset parameters, the near field communication connection is established with the near field communication equipment again until the near field communication connection is established successfully, and the success rate of the near field communication connection between the mobile terminal and the near field communication equipment can be improved.
