BACKGROUND With the development of mobile communication technologies, various mobile terminal devices such as mobile phones, PDAs, and tablet computers are becoming more and more popular, which brings great convenience to people's lives. And with the continuous improvement of the hardware and software design and manufacturing level, various mobile terminals are getting smaller and smaller, more portable, and more and more applications and services are provided. With the increasing demand for data transmission between mobile terminals, NFC functions have emerged, and NFC is a short-range wireless communication technology. It is a contactless identification and interconnection technology initiated by Philips, Nokia and Sony. It is one of the current multi-application hotspot technologies based on mobile phones, and is the mainstream technology for non-contact IC card applications to integrate mobile terminals. Near Field Communication (NFC) is a wireless connection technology that provides easy, secure, and fast communication. Its transmission range is smaller than Radio Frequency IDefication (RFID). The transmission range of RFID can be Up to several meters, even tens of meters, but because NFC adopts a unique signal attenuation technology, NFC has the characteristics of close distance, high bandwidth and low energy consumption compared with RFID.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. Embodiment 1 The embodiment of the present invention provides an NFC communication method. FIG. 1 is a flowchart of an NFC communication method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps: Step S102: Passing an NFC static label Pairing the communication identifier information of the other party; Step S104, establishing a first data link with the other party according to the acquired communication identifier information of the other party; Step S106, negotiating the second connection mode with the other party through the first data link, and selecting according to the negotiation The second connection mode is connected with the other party to establish a second data link. Through the above steps, the first data link is established with the other party through the NFC static label, and the second data link is negotiated with the other party through the first data link to establish a second data link, which directly changes the related technology through the NFC static label. The practice of establishing a second data link has the effect of extending the NFC static tag. After the second data link is established, the data in the processor of the terminal with the NFC static tag is also obtained, and the data in the acquired processor is sent to the other party through the second data link. In the face of the increasingly competitive smart terminal market, it is the ultimate goal of developers and users to achieve more powerful functions at lower cost.

In various modes of NFC application, since the cost of the NFC static tag in the NFC static tag mode is lower than that of the NFC chip, the mode is used by more and more mainstream intelligent terminal applications to establish short-distance data reading and writing functions. However, the function that can be implemented in this mode is limited compared to the NFC point-to-point communication mode, and only static data can be read and written. The data communication function between the NFC static tag and its terminal processor is not available. Therefore, how to change the label in the NFC reading mode to reach the NFC point-to-point communication function is of great significance. Through the above steps, the NFC static tag mode, which can only transmit static data, is converted into an NFC point-to-point communication mode that can transmit dynamic data, which reduces the cost and achieves a better user experience. The first data link acquires the communication identifier of the other party through the NFC static tag, such as the mobile number information of the other party, and establishes a network channel in the wireless mobile network. The first data link is used to transmit control information for negotiating the establishment of the second data link. There may be many types, and preferably, it may be a short message link, a WIFI or a Bluetooth link. Through the above steps, a short message link or a data link is established, and a data channel is provided for negotiating the second connection mode, which changes the practice of directly establishing the second data link through the NFC static tag in the related art. The second data link may have a plurality of types, and preferably may be a wireless long-distance data link to complement the NFC. After the first data link is established, the status of the Bluetooth or WIFI port of the terminal with the NFC static tag can be detected, and the status of the Bluetooth or WIFI port is sent to the other party through the first data link, and the second connection mode is negotiated with the other party. The second connection mode is a Bluetooth connection mode or a WIFI connection mode. Compared with Bluetooth, NFC is suitable for close-range transactions and is suitable for exchanging important information such as financial information or sensitive personal information. Bluetooth or WIFI can make up for the shortcomings of NFC communication distance, and is suitable for long-distance data communication. Therefore, the second connection mode is preferably a WIFI connection mode or a Bluetooth connection mode, to establish a second data link, that is, a WIFI or Bluetooth connection data link, to make up for the shortcoming of insufficient NFC communication distance, and the first data link transmission. The problem of insufficient capacity. There are many ways to obtain the communication identifier information of the other party through the NFC static label. Preferably, the NFC static label can be paired with the NFC chip of the other party to obtain the communication identifier information of the other party. In other embodiments, the static identifier may be paired with the static label of the other party to obtain the communication identifier information of the other party. The second embodiment of the present invention further provides an NFC communication device, which is used to implement the foregoing embodiments and preferred embodiments, and has not been described again. As used hereinafter, the term "module" may implement a combination of software and/or hardware of a predetermined function. Although the apparatus described in the following embodiments is preferably implemented in software, hardware, or a combination of software and hardware, is also possible and conceivable. FIG. 2 is a structural block diagram of an NFC communication device according to an embodiment of the present invention. As shown in FIG. 2, the device includes an identifier obtaining module 202, a link establishing module 204, and an application module 206. The identifier obtaining module 202 is configured to obtain the counterpart communication identifier information by using the NFC static tag pairing. The link establishing module 204 is configured to establish a first data link with the other party according to the acquired counterpart communication identification information. The application module 206 is configured to negotiate a second connection mode with the other party through the first data link, and connect with the other party according to the second connection mode selected by negotiation to establish a second data link. Preferably, the application module 206 is further configured to acquire data in a processor of the terminal with the NFC static tag and transmit the data in the acquired processor to the other party through the second data link. Preferably, the application module 206 is further configured to detect the Bluetooth or WIFI port status of the terminal with the NFC static tag, send the Bluetooth or WIFI port status to the other party through the first data link, and negotiate with the other party to select the second connection mode, where The second connection mode is a Bluetooth connection method or a WIFI connection method. Preferably, the first data link is used to transmit control information used to negotiate to establish the second data link. In a preferred embodiment of the present invention, the components in the device can be combined with each other to complete the corresponding functions according to the method described in the first embodiment, and have the same beneficial effects. . Embodiment 3 In this embodiment, the sender includes an NFC chip, and the receiver includes an NFC static label. The sender in this embodiment is equivalent to the other party in the first embodiment, and the receiver is equivalent to the NFC static label in the first embodiment. Terminal. 3 is a flow chart of an NFC communication method in accordance with a preferred embodiment of the present invention. As shown in Figure 3, the process includes the following steps: Step S302: The receiver communication identifier information is obtained by pairing the NFC chip with the NFC static tag. The sender contacts the receiver in close proximity, and the sender's communication identifier information is obtained by pairing the NFC chip of the sender with the NFC static tag of the receiver, for example, obtaining information such as a mobile number. Step S304, establishing a first data link by using a wireless network. And establishing, according to the obtained sender communication identifier information, establishing a first data link by using a wireless network, for example, establishing a connection between the receiver and the sender by using a short message link manner or a data link manner. Step S306, the receiver acquires data in its processor and detects Bluetooth and WIFI port status. The receiver obtains data in its processor through its application module and detects if the Bluetooth/WIFI port is open. Step S308, the receiver notifies the sender of the connection mode selected. The receiver sends a response message to the sender through the first data link in response to the selected connection mode.

(WIFI/Bluetooth). The response information is sent to the sender over the first data link. The first data link is used to transmit control information for negotiating to establish a second data link, where the control information includes status information of the Bluetooth and/or WIFI port. Step S310, establishing a second data link. The receiver and the sender perform corresponding connections according to the connection mode selected by negotiation, such as Bluetooth pairing or

The authentication connection of the WIFI establishes a second data link. Step S312, the acquired data of the receiver processor is transmitted through Bluetooth or WIFI. Applying the established second data link, the receiver sends the data acquired in step S306 to the sender. In the related art, the NFC static tag and the sender have no information handshake process. When the sender approaches the receiver, the receiver, that is, the terminal equipped with the NFC static tag, can send the optional data link to the sender (Bluetooth/ WIFI) response. Through the above steps, a handshake-like operation can be established, and the receiver can use the newly created application module to perform data transmission operations with the own processor, thereby implementing the function of the NFC point-to-point data communication mode through the NFC static tag.

The sender 402 contacts the receiver 404 in close proximity, pairs with the NFC chip 4024 through the NFC static tag 4044, and obtains the communication identification information of the sender 402, and then the sender 402 and the receiver 404 establish a first data link by using the communication identification information, for example, The short message or data link, etc., and then the data exchange between the application module 206 and the receiver processor 4042 added by the receiver 404, and the detection of the port of the receiver WIFI 4048 or the receiver Bluetooth 4046, and the response information is sent to the sender 4022. So that the sender 402 knows the status of the receiver WIFI 4048 or the receiver Bluetooth 4046 port, thereby establishing a WIFI or Bluetooth data connection between the sender 402 and the receiver 404. In the related art, in the NFC static label mode, a mobile terminal with an NFC chip is a sender close to another mobile terminal with an NFC static label, that is, a receiver, and the receiver directly transmits a response to whether the Bluetooth/WIFI port is turned on. Side, and there is no deep interaction between the NFC static tag and the receiver processor, only the reading and writing of static data. If it is the communication step in this embodiment, the handshake protocol between the two mobile terminals can be formed by adding a short message/data link manner, and the receiving party can pass the application layer of the application layer 206 after receiving the data link information. The receiver processor 4042 performs the interaction of the data information to achieve the same effect as the NFC point-to-point communication. It can be seen from the above description that the embodiment of the present invention achieves the following technical effects: The embodiment of the present invention uses an NFC static tag that is cheaper than the NFC chip, and can only transmit static data by adding a short message/data link.
