Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail and completely with reference to the following embodiments and accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
During NFC communication, two NFC devices participating in communication need to be in a "card mode" and a "card reader mode", respectively. The NFC equipment in the card reader mode determines a communication signal with a specific waveform to transmit according to a communication protocol; and the NFC device in "card mode" replies after recognizing the waveform of the communication signal.
However, in the prior art, due to characteristics and setting of different NFC devices, waveforms of modulated communication signals of different NFC devices have certain differences. The difference is expressed by the fact that the waveforms differ in phase, modulation depth, and the like. And the difference often causes compatibility problems between different devices, thereby reducing communication efficiency and even failing to realize normal communication.
In view of the above, the present invention provides an NFC communication method. The method is applied to the first type of NFC device. In other words, the main body, i.e., the first type NFC device is executed in the present embodiment. By NFC device of the first type, it is meant an NFC device in "reader mode". And the corresponding NFC device of the second type is an NFC device in "card mode". The first type of NFC device and the second type of NFC device are both parties participating in NFC communication. Referring to fig. 1, a specific embodiment of an NFC communication method provided in the present invention is shown. In this embodiment, the method includes the steps of:
A second type of NFC device may support a different NFC protocol. The specific communication signal and waveform characteristics may also vary between different NFC protocols. The target NFC protocol, i.e. the NFC protocol that needs to be agreed on the waveform of the communication signal, should first be determined in this embodiment.
When the first type of NFC device communicates by using the target NFC protocol, its communication signal may exhibit a certain waveform characteristic based on its own property. In this embodiment, the so-called "waveform protocol" is that the NFC device of the second type may adjust its own communication signal according to the waveform characteristics of the NFC device of the first type. The waveform characteristics of the communication signals sent by the second type of NFC equipment are closer to those of the first type of NFC equipment, so that the compatibility and the communication efficiency between the second type of NFC equipment and the first type of NFC equipment are improved.
Therefore, in this step, the waveform description information corresponding to the first type of NFC device is determined according to the target NFC protocol. The waveform description information is information describing waveform characteristics of the first type of NFC device under the target NFC protocol. The waveform description information may specifically include a frame latency parameter and a release collision phase parameter.
After the waveform description information is determined, the waveform protocol command may be further determined according to the waveform description information. That is, the waveform protocol command carries the waveform description information. Under the condition that the waveform description information comprises a frame waiting time parameter and a release conflict phase parameter, the process of determining the waveform agreement instruction specifically comprises the following steps:
determining an instruction identifier of a waveform agreement instruction; checking the command identifier, the frame waiting time parameter and the release conflict phase parameter to determine check bytes; determining the waveform agreement instruction according to the instruction identifier, the frame latency parameter, the put collision phase parameter, and the check byte.
The format of the wave protocol command can be referred to the following table:
| CMD | FDT | Phase | CRC |
a total of 4 parts are included in the waveform protocol command. Wherein, CMD represents a command identifier of the waveform protocol command, and the command identifier will occupy 1 byte, and may be specifically a character such as a letter, a number, and the like. FDT represents a frame latency parameter, which occupies 1 byte, and is essentially a time parameter in microseconds (μ s), meaning a time difference value that a waveform needs to be adjusted based on a protocol specification. Phase represents the Phase parameter of conflict, occupies 1 byte, is an angle parameter in nature, and means the Phase difference value of the waveform needing to be adjusted on the basis of the protocol specification. The CRC represents a check byte, and is determined by checking the command identifier, the frame latency parameter, and the put collision phase parameter, taking 2 bytes.
After determining the waveform protocol command, the first type of NFC device needs to send the waveform protocol command to the corresponding second type of NFC device. This second type of NFC device, i.e. the "card mode" NFC device, is in the radio frequency field of the first type of NFC device and needs to communicate with it. In this embodiment, the NFC device of the second type does not need to reply to the waveform agreement command.
After sending the waveform agreement instruction to the second type of NFC device, according to a normal NFC communication flow, the first type of NFC device needs to send an activation instruction to the second type of NFC device to activate the second type of NFC device, so as to enter a state where actual communication can start. The activation instruction may specifically be an ALL _ REQ instruction or a SENS _ REQ instruction in the art. Normally, the NFC device of the second type will respond to the activation instruction and send feedback information to the NFC device of the first type. In this embodiment, since the NFC device of the second type does not need to reply to the waveform protocol command, the protocol result of the NFC device of the second type for the waveform protocol command is also carried in the feedback information. Therefore, the number of communication interaction between the two can be reduced, and the communication flow is simplified. And the agreement result shows whether the NFC equipment of the second type can send out communication signals in an agreed manner.
And step 104, determining an agreement result corresponding to the waveform agreement instruction according to the feedback information of the second type of NFC equipment.
After receiving the feedback information, the first type of NFC device may resolve the agreement result. Thereby knowing whether the NFC devices of the second type can cooperatively emit communication signals to present a waveform consistent therewith.
It should be further noted in this embodiment that, in some cases, the number of the target NFC protocols may be multiple. I.e. the NFC devices of the second type may support multiple NFC protocols or it may need to be determined which NFC protocol is supported by the NFC devices of the second type at all. In this case, the respective target NFC protocols should be agreed upon in turn, as shown in fig. 2.
That is to say, the first type of NFC device needs to determine waveform description information corresponding to each target NFC protocol, and then determine a waveform protocol instruction corresponding to each target NFC protocol according to the waveform description information corresponding to each target NFC protocol.
Then, sequentially sending the waveform protocol instruction corresponding to each target NFC protocol to the second type of NFC equipment; and correspondingly sending an activation instruction to the second type of NFC equipment after the waveform protocol instruction is sent each time. Sending an activation instruction to the second type of NFC equipment according to each time, and receiving corresponding feedback information; and determining an agreement result of the waveform agreement instruction corresponding to each target NFC protocol according to each piece of feedback information.
For example, in fig. 2, three target NFC protocols, NFC-A, NFC-B and NFC-F, are included. In the flow shown in fig. 2, after one target NFC protocol agreement is completed, the agreement of the next target NFC protocol is performed in sequence. The agreement procedure of each target NFC protocol is consistent with the above steps. The above process is repeated to complete the agreement of multiple target NFC protocols.
So far, the communication signal waveform protocol between the first type of NFC device and the second type of NFC device is implemented in this embodiment.
Fig. 3 shows another specific embodiment of an NFC communication method according to the present invention. The method in this embodiment is applied to the above-described NFC device of the second type. In other words, the main body, i.e., the NFC device of the second type, is implemented in this embodiment. In fact, the method in this embodiment is a communication process performed synchronously by the NFC device of the second type while the method steps in the embodiment shown in fig. 1 are performed. The two cooperate with each other to complete the waveform protocol of the communication signal. The method in this embodiment includes the following steps:
The second type of NFC device may determine a corresponding agreement result after receiving the waveform agreement instruction. I.e. whether a communication signal can be sent out according to an agreement. In some cases, if the second type of NFC device does not support the target NFC protocol, the agreement typically results in an "agreement failure. Otherwise, if the target NFC protocol is supported, the agreement result may be "agreement success".
NFC devices of the second type do not reply to the waveform agreement instruction. But rather needs to reply with feedback information to the NFC device of the first type in response to the activation instruction. At this time, the agreement result may be carried in the feedback information.
In the case that the agreement result is "agreement is successful", the NFC device of the second type may determine the waveform of the communication signal according to the waveform agreement instruction. Namely, the waveform in the communication signal is adjusted according to the frame waiting time parameter and the conflict phase parameter in the waveform protocol command.
After the waveform of the communication signal is determined, the second type of NFC equipment can perform NFC communication with the first type of NFC equipment by using the adjusted communication signal in the subsequent actual NFC communication process. Namely, the protocol of communication signals is achieved, and the communication compatibility and the communication efficiency of the two are improved.
As can be seen from the embodiments shown in FIGS. 1 to 3, the beneficial effects of the present invention are: the first class of NFC equipment sends a waveform protocol command to the second class of NFC equipment, so that a communication signal waveform protocol between the first class of NFC equipment and the second class of NFC equipment is realized; the waveform difference between different devices is avoided, the compatibility problem between different devices is solved, the communication efficiency is improved, and the communication fault is also avoided.
