[0021] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be construed as limitations on the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0022] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0023] In the following description, the terms "first / second / third" are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0025] Before further elaborating on the embodiments of the present application, the nouns and terms involved in the embodiments of the present application are described. The nouns and terms involved in the embodiments of the present application are applicable to the following explanations.

[0026] Ultra Wide Band (UWB) technology is a wireless carrier communication technology. It does not use sinusoidal carriers, but uses non-sinusoidal narrow pulses in the nanosecond level to transmit data. It has the advantages of simple system structure, low transmit signal power spectral density, being insensitive to channel fading, low interception ability, and high positioning accuracy. It is especially suitable for high-speed wireless access in dense multipath places such as indoors.

[0027] Currently, when a mobile phone is located via UWB signals or other items are located, it is usually by configuring UWB tags on the mobile phone or other items, receiving UWB signals through the UWB tags, and positioning based on the UWB signals. Here, the mobile phone and the UWB tag can be configured with NFC coils to perform near-field communication through the RF field of the NFC coils. In this way, when the mobile phone is close to other NFC electronic devices, it will cause the mobile phone to be unable to perform near-field communication with third-party near-field communication devices, and the flexibility of near-field communication between the mobile phone and the UWB tag is low, thus affecting other near-field communication functions of the mobile phone, such as: bus card swiping, mobile payment, identity recognition, etc.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0029] The embodiments of the present application provide a communication tag, as Figure 1 shown. The communication tag 1 includes: a signal transmission module 11 and a wireless charging module 12; the wireless charging module 12 is connected to the signal transmission module 11; the wireless charging module 12 is used to generate a power supply electrical signal based on the induced electromagnetic field of the terminal and supply power to the signal transmission module 11 through the power supply electrical signal; the signal transmission module 11 is used to perform near-field communication with the terminal during the communication time period of the current communication cycle when powered on; and, in response to the communication pause indication information received during the communication time period of the current communication cycle, pause the near-field communication with the terminal within a preset first time period after the current communication cycle.

[0030] In the embodiments of the present application, near-field communication may include: Bluetooth communication, Wireless Fidelity (Wi-Fi), Near Field Communication (NFC). In the following embodiments, near-field communication is described by taking NFC as an example.

[0031] Near Field Communication (NFC) technology is developed by combining wireless interconnection technology on the basis of non-contact radio frequency identification (RFID) technology. "Near field" refers to radio waves near the electromagnetic field; radio waves are actually electromagnetic waves, which follow Maxwell's equations. During the process of propagating from the transmitting antenna to the receiving antenna, the electric field and the magnetic field will continuously alternate in energy conversion and enhance each other when converting; within 10 wavelengths of the electromagnetic wave, the electric field and the magnetic field are independent of each other. At this time, the electric field doesn't have much significance, but the magnetic field can be used for short-distance communication, which we call near field communication.

[0032] In the embodiment of the present application, the signal transmission module 11 is used to transmit the NFC communication signal to the NFC communication signal between terminals; the communication information is sent to the terminal through the NFC communication signal.

[0033] In the embodiment of the present application, the communication tag 1 is configured with an information signal receiving device to receive the information signal through the information signal receiving device; the communication tag can obtain the communication information through the information receiving signal and send the communication information to the terminal through the NFC radio frequency signal; thus, the terminal can obtain the communication information in the NFC radio frequency signal through the communication tag.

[0034] In the embodiment of the present application, the information signal can be a UWB signal, a Bluetooth signal, or a Wireless Fidelity (Wi-Fi) signal, etc.; in this regard, it can be set according to needs, and the embodiment of the present application does not make any restrictions.

[0035] In the embodiment of the present application, when the communication tag 1 is powered on, it means that the signal transmission module 11 is powered; at this time, the communication tag 1 can send an NFC radio frequency signal to the terminal through the signal transmission module 11 as the communication signal between the communication tag and the terminal.

[0036] In the embodiment of the present application, the wireless charging module 12 can directly supply power to the signal transmission module 11, or charge the battery of the communication tag and then supply power to the signal transmission module 11 through the battery; the embodiment of the present application does not make any restrictions on the power supply method of the wireless charging module 12.

[0037] In the embodiments of the present application, after the communication tag establishes a communication connection with the terminal, the communication tag can periodically turn on and off the first NFC radio frequency field of the communication tag to achieve periodic communication with the terminal; here, the time period when the first NFC radio frequency field is turned on is the communication time period, and the time period when the first NFC radio frequency field is turned off is the non-communication time period; a communication cycle includes a communication time period and a non-communication time period; the communication tag can send communication signals to the terminal through the first NFC radio frequency field during the communication time period of any communication cycle.

[0038] In the embodiments of the present application, the communication tag can periodically supply power to the first NFC coil of the communication tag; thus, during the power supply time period, the first NFC radio frequency field of the first NFC coil is turned on, and the power supply time period is the communication time period; during the non-power supply time period, the first NFC radio frequency field of the first NFC coil is turned off, and the non-power supply time period is the non-communication time period.

[0039] In the embodiments of the present application, if the signal transmission module 11 receives the communication pause indication information from the terminal during the communication time period of the current communication cycle, it turns off the first NFC radio frequency field within a preset first time period after the current communication cycle, so as to pause the NFC communication with the mobile phone within the preset first time period after the current communication cycle.

[0040] In the embodiments of the present application, the communication pause indication information indicates that the terminal detects the radio frequency field of a third-party NFC device and needs to perform NFC communication with the third-party NFC device within a preset first time period after the current communication cycle to implement the NFC function related to the third-party NFC device.

[0041] In the embodiments of the present application, the preset first time period can be a period of time after the end of the communication time period of the current communication cycle, or a period of time after the end of the current communication cycle; here, the preset first time period can be represented by a time length, such as 1s, 2s, etc., or can be represented by N communication cycles, where N is a positive integer greater than or equal to 10; such as 10 communication cycles, 12 communication cycles, etc.; for the preset first time period, it can be set according to actual needs, and the embodiments of the present application do not limit this.

[0042] In the embodiments of the present application, the terminal includes a transmitting coil, and the wireless charging module 12 includes a receiving coil; when the transmitting coil is energized, an induced electromagnetic field is generated; thus, the receiving coil can sense the induced electromagnetic field of the terminal and generate a power supply current in the receiving coil to supply power to the signal transmission module through the power supply current.

[0043] In some embodiments of the present application, the transmitting coil of the terminal can be used to generate a charging current to charge the terminal.

[0044] It can be understood that after the communication tag is powered on by the wireless charging module, periodic NFC communication with the terminal can be achieved through the signal transmission module; and after receiving the communication pause instruction information from the terminal, the NFC communication with the terminal can be paused, enabling the terminal to implement the NFC function related to the third-party NFC device during the communication pause period, thereby improving the communication flexibility between the communication tag and the terminal.

[0045] In some embodiments of the present application, with reference to Figure 2 , the signal transmission module 11 includes an NFC switch 112, a first NFC coil 111, and a signal acquisition module 113; the NFC switch 112 is disposed between the first NFC coil 111 and the signal acquisition module 113; the wireless charging module 12 is connected to the signal acquisition module 113; the signal acquisition module 113 communicates with the NFC switch 112; the wireless charging module 12 is configured to generate a power supply electrical signal based on the induction electromagnetic field of the terminal and supply power to the signal acquisition module 113 through the power supply electrical signal; the signal acquisition module 113 is configured to acquire communication signals; and when powered on, close the NFC switch 112 during the communication time period of the current communication cycle to conduct the first NFC coil 111, so as to send the communication signals to the terminal through the first NFC coil 111; and in response to the communication pause instruction information, disconnect the NFC switch 112 within a preset first time period, thereby pausing the NFC communication between the communication tag and the terminal.

[0046] In the embodiments of the present application, the wireless charging module 12 is used to supply power to the signal acquisition module 113. When the signal acquisition module 113 is powered, the signal acquisition module 113 can acquire communication signals; and the signal acquisition module 113 can control the NFC switch 112 to periodically close the NFC switch 112 during the communication time period of the current communication cycle and periodically disconnect the NFC switch 112 during the communication time period of the current communication cycle, so as to conduct the first NFC coil 111 during the communication time period of the current communication cycle and disconnect the first NFC coil 111 during the non-communication time period of the current communication cycle; thus, the communication tag can turn on the first NFC radio frequency field during the communication time period of the current communication cycle and perform NFC communication with the terminal through the first NFC radio frequency field.

[0047] In the embodiment of the present application, during the communication time period of the current communication cycle, the signal acquisition module 113 receives an NFC communication signal carrying communication pause indication information from the terminal through the conducting first NFC coil 111. In this way, the signal acquisition module 113 can respond to the communication pause indication information and disconnect the NFC switch 112 within a preset first time period after the communication time period of the current communication cycle, thereby disconnecting the first NFC radio frequency field. In this way, the communication tag pauses NFC communication with the terminal within the preset first time period.

[0048] In the embodiment of the present application, the signal acquisition module 113 is communicatively connected to the NFC switch 112. The signal acquisition module 113 can periodically send control signals to the NFC switch 112 to control the periodic disconnection and closing of the NFC switch 112. Here, the control signals include a disconnection control signal and a closing control signal.

[0049] In the embodiment of the present application, when the signal acquisition module 113 is in the case where the NFC switch 112 is closed, that is, during the communication time period of the current communication cycle, if it receives communication pause indication information from the terminal, it can continuously disconnect the NFC switch 112 within a preset first time period after the end of the communication time period of the current communication cycle. Thus, within the preset first time period, the power supply to the first NFC coil 111 is stopped, the first NFC radio frequency field is turned off, and the NFC communication with the terminal is paused.

[0050] It can be understood that by controlling the periodic closing and disconnection of the NFC switch by the signal acquisition module, periodic communication can be carried out between the communication coil and the terminal, and the implementation is simple.

[0051] In some embodiments of the present application, as Figure 3 shown, the signal acquisition module 113 may include: a UWB receiving module 1131, a micro control unit (MCU) 1132, and an NFC control module 1133. The micro control unit 1132 is disposed between the UWB receiving module 1131 and the NFC control module 1133. The micro control unit 1132 communicates with the NFC switch 112. The UWB receiving module 1131 is configured to receive UWB signals and transmit the UWB signals to the micro control unit 1132. The micro control unit 1132 is configured to generate communication information based on the UWB signals and transmit the communication information to the NFC control module 1133. And, close the NFC switch 112 during the communication time period of the current communication cycle. The NFC control module 1133 is configured to carry the communication information in the NFC signal and adjust the transmission energy of the NFC signal to obtain a communication signal.

[0052] In the embodiments of the present application, the communication tag is a UWB tag, which is used for the UWB signals of other UWB devices, generates communication information based on the UWB signals; carries the communication information in the communication signal and sends it to the terminal; in this way, the terminal can locate the UWB device through the communication information.

[0053] In the embodiments of the present application, the communication information may be information such as distance, angle, or distance and angle determined based on the UWB signal; it may also be information carried in the UWB signal; in this regard, the embodiments of the present application do not make any restrictions.

[0054] Here, the UWB device may be a device with a built-in UWB receiving antenna, which sends or receives UWB signals through UWB; the UWB device may also be a device configured with a UWB tag; in this regard, the embodiments of the present application do not make any restrictions.

[0055] In some embodiments of the present application, other communication information sent by the UWB device may also be carried in the UWB signal, for example, key information, configuration information, etc.; in this way, the terminal obtains the information sent by the UWB device through the communication tag from the UWB signal.

[0056] In the embodiments of the present application, after the UWB receiving module 1131 receives the UWB signal, it transmits the UWB signal to the micro control unit 1132; in this way, the micro control unit 1132 can obtain the communication information based on the UWB signal; transmit the communication information to the NFC control module 1133, the NFC control module adjusts the transmission energy of the NFC signal to obtain an adjusted NFC signal, then carries the communication information in the adjusted NFC signal to obtain a communication signal; and sends the communication signal through the first radio frequency field of the conducting first NFC coil to the terminal.

[0057] In some embodiments of the present application, the UWB receiving module 1131 includes a UWB receiving antenna and a UWB module; wherein, the UWB receiving antenna is used to receive the UWB signal; the UWB module is used to obtain UWB information based on the UWB signal and then send the UWB information to the micro control unit 1132.

[0058] Here, the UWB receiving antenna includes at least two antennas, and the UWB information may include the reception time difference, reception phase difference, reception distance, etc. of the UWB signals received between at least two antennas pairwise; after the micro control unit 1132 obtains the UWB information, it may directly use the UWB information as the communication information; or it may obtain a positioning result based on the UWB information and use the positioning result as the communication information; the communication information can be set as needed, and the embodiments of the present application do not make any restrictions.

[0059] In the embodiments of the present application, the microcontroller unit 1132 communicates with the NFC switch 112 and the NFC control module 1133 respectively, and the communication tag controls the closing and opening of the NFC switch 112 through the microcontroller unit 1132.

[0060] In the embodiments of the present application, the NFC switch 112 is disposed between the NFC control module 1133 and the first NFC coil 111. After obtaining the communication signal, the NFC control module 1133 transmits the communication signal to the terminal through the first NFC coil 111 when the NFC switch 112 is closed.

[0061] It can be understood that the communication tag can receive the UWB signal through the UWB receiving module, and then based on the UWB signal, send the UWB information or other information carried in the UWB signal to the terminal, so that the terminal can implement UWB communication with the UWB device through the communication tag.

[0062] In some embodiments of the present application, as Figure 4 shown, the NFC control module 1133 includes: a secure storage module (Secure Element, SE) 1134; the secure storage module 1134 is used to store communication information.

[0063] In the embodiments of the present application, after determining the communication information, the microcontroller unit 1132 transmits the communication information to the NFC control module 1133 and stores it in the secure storage module 1134. During the communication time period of the current communication cycle, the communication information is obtained from the secure storage module 1134 and sent to the terminal.

[0064] It can be understood that by storing the communication information in the secure storage module, the security of the communication information can be improved.

[0065] In some embodiments of the present application, referring to Figure 5 , the wireless charging module 12 includes: a receiving coil 121, a rectifying module 122, and a wireless charging control module 123; the receiving coil 121 is used to generate an induced electrical signal based on the induced electromagnetic field of the transmitting coil of the terminal and transmit the induced electrical signal to the rectifying module 122; the rectifying module 122 is used to convert the induced electrical signal from an alternating current signal into a direct current signal to obtain a rectified signal; the wireless charging control module 123 is used to regulate the voltage based on the rectified signal to obtain a power supply electrical signal; and transmit the power supply electrical signal to the signal transmission module 11 for power supply.

[0066] In the embodiment of the present application, the receiving coil 121 is located in the induced electromagnetic field of the transmitting coil of the terminal. If the transmitting coil of the terminal is powered on, the transmitting coil will generate an induced electromagnetic field. Thus, the receiving coil 121 can generate an induced electrical signal in response to the induced electromagnetic field, and transmit the induced electrical signal to the rectification module 122.

[0067] Here, the terminal can be a terminal with wireless charging function. The transmitting coil of the terminal can generate an induced electrical signal by inducing the electromagnetic field of other coils, and charge the terminal through the induced current.

[0068] In the embodiment of the present application, the induced electrical signal is an alternating current signal. After passing through the rectification module 122, the alternating current signal will be converted into a direct current signal. Thus, the wireless charging control module 123 regulates the voltage of the direct current signal to obtain a regulated electrical signal as the power supply electrical signal, and provides the power supply electrical signal to the signal transmission module for power supply.

[0069] In some embodiments of the present application, the wireless charging control module 123 needs to supply power to the micro-control unit 1132, the UWB receiving module 1131, and the NFC control module 1133 respectively. At this time, the wireless charging controller can perform the first voltage regulation, the second voltage regulation, and the third voltage regulation on the direct current signal to obtain the first power supply electrical signal, the second power supply electrical signal, and the third power supply electrical signal, supply power to the micro-control unit 1132 through the first power supply electrical signal, supply power to the UWB receiving module 1131 through the second power supply electrical signal, and turn on the function of the UWB receiving module 1131; supply power to the NFC control module 1133 through the third power supply electrical signal.

[0070] It should be noted that the voltages of the first power supply electrical signal, the second power supply electrical signal, and the third power supply electrical signal can be the same or different. In this regard, the embodiments of the present application do not make any restrictions.

[0071] It can be understood that for a terminal with wireless charging function, if the transmitting coil of the terminal is powered on, the communication tag can generate an induced electrical signal in response to the induced electromagnetic field of the transmitting coil through the receiving coil, and obtain the power supply electrical signal based on the induced electrical signal, so as to power on the communication tag.

[0072] In some embodiments of the present application, the signal transmission module 11 is further configured to send a power supply completion message to the terminal during the communication time period of the communication cycle after receiving the power supply electrical signal; and, based on the UWB configuration information fed back in response to the power supply completion message by the terminal.

[0073] In the embodiment of the present application, after the signal transmission module 11 receives the power supply electrical signal and is thus powered on, it can send a power supply completion message to the terminal during the communication time period of the communication cycle after receiving the power supply electrical signal, prompting the terminal that the communication tag has been powered on and can operate normally.

[0074] In an embodiment of the present application, after the communication tag sends power supply completion information to the terminal, it can receive UWB configuration information from the terminal through the signal module 11; here, the UWB configuration information is used to configure the communication information required by the terminal.

[0075] Exemplarily, if the UWB configuration information indicates that the terminal needs to obtain the angle information of other UWB devices, the signal transmission module 11 determines the angle information based on the received UWB signal and uses the angle information as the communication information.

[0076] It can be understood that after the communication tag is powered on, it can notify the terminal so that the terminal can establish a communication connection with the communication tag, and then perform NFC communication during the communication time period in the current communication cycle.

[0077] In some embodiments of the present application, the secure storage module 1134 is further configured to store the tag identity information; and be pulled by the terminal to obtain the tag identity information in the passive working mode for the terminal to identify whether the communication tag and the terminal match based on the tag identity information; the wireless charging module 12 is further configured to, when the terminal and the communication tag match, generate a power supply electrical signal based on the induced electromagnetic field, supply power to the signal transmission module through the power supply electrical signal, and enable the communication tag to perform near-field communication with the terminal during the communication time period in the current communication cycle in the active working mode.

[0078] In an embodiment of the present application, when the communication tag is not powered on, it is in the passive working mode. In the passive working mode, the communication tag cannot actively send communication information to the terminal and can only be read by the terminal for the tag identity information pre-burned in the secure storage module 1134.

[0079] In an embodiment of the present application, the tag identity information is information used to verify whether the communication tag and the terminal match; if the terminal verifies that the tag identity information matches the terminal, the terminal will power on the transmitting coil. In this way, the communication tag can induce the induced electromagnetic field of the transmitting coil through the receiving coil, generate a power supply electrical signal, supply power to the signal transmission module 11 through the power supply electrical signal, and thus the communication tag is powered on. After the communication tag is powered on, the micro-control unit 1132 switches the working mode of the communication tag to the active working mode. In the active working mode, if the communication tag establishes a communication connection with the terminal, it can perform in-field communication with the terminal during the communication time period in the current communication cycle.

[0080] It should be noted that when the communication tag is not powered on, the NFC switch 112 is in the closed state; thus, the terminal can read the tag identity information in the secure storage module 1134 through the first NFC coil 111.

[0081] It can be understood that the communication tag will be powered only when the tag identity information of the communication tag matches, and then a communication connection with the terminal is established to perform NFC communication with the terminal during the communication time period within the current communication cycle; this improves the effectiveness of the communication tag being powered by the terminal and saves the power consumption of the terminal.

[0082] In some embodiments of the present application, the signal transmission module 11 is further configured to, if no UWB signal is received within a preset duration, send stop power supply indication information to the terminal during the communication time period of the communication cycle after the preset duration.

[0083] In an embodiment of the present application, if the signal transmission module 11 does not receive a UWB signal within a preset duration, it cannot generate new communication information; thus, during the communication time period of the communication cycle after the preset duration, the signal transmission module 11 can send stop power supply indication information to the terminal to stop the terminal from supplying power to the communication tag, so that the communication tag stops operating, thereby disconnecting the communication connection with the terminal and returning to the passive working mode.

[0084] It can be understood that if the communication tag does not receive a UWB signal for a continuous period of time, it can be powered off and stop operating to save the power consumption of the communication tag.

[0085] In some embodiments of the present application, the signal transmission module 11 is further configured to continue to perform NFC communication with the terminal during the communication time period of the communication cycle after a preset first time period.

[0086] In an embodiment of the present application, if the signal transmission module 11 pauses communication with the terminal within a preset first time period, it will continue to perform NFC communication with the terminal during the communication time period of the communication cycle after the preset first time period.

[0087] Exemplarily, referring to Figure 6 , Figure 6 shows a schematic structural diagram of a communication tag, as Figure 6As shown, the UWB receiving module is implemented as a UWB module, a UWB receiving antenna 1, and a UWB receiving antenna 2; both the UWB receiving antenna 1 and the UWB receiving antenna 2 are connected to the UWB module, and the UWB module is connected to an MCU, an NFC control module, an NFC switch, and a first NFC coil; the receiving coil is sequentially connected to a rectification module and a wireless charging control module, and the wireless charging control module is connected to the MCU, the NFC control module, and the UWB module to supply power to the MCU, the NFC control module, and the UWB module; the MCU communicates with the NFC control module and the NFC switch, and the NFC control module communicates with the UWB module.

[0105] Based on the above communication method, referring to Figure 9 , an embodiment of the present application provides a schematic diagram of the interaction process between a communication tag and a terminal, as shown in Figure 9 and the method may include:

[0106] S201. When the terminal turns on the positioning application, it reads the tag identity information of the communication tag.

[0107] In the embodiment of the present application, the positioning application is an application program that needs to use UWB signals for positioning; after the positioning application is turned on, it will trigger the terminal to read the tag identity information of the communication tag.

[0108] S202. If the terminal determines that the tag identity information matches itself, it powers on the communication tag.

[0109] S203. After being powered on, the communication tag establishes a communication connection with the terminal and sends a power supply completion message to the terminal.

[0110] In the embodiment of the present application, after the communication tag is powered on, the UWB receiving module, the MCU, and the NFC control module are powered on.

[0112] In the embodiment of the present application, the UWB configuration information corresponds to the positioning application; that is, the terminal determines the UWB configuration information according to the opened positioning application and sends the UWB configuration information to the communication tag; the communication tag can obtain the communication information corresponding to the UWB configuration information based on the UWB signals. In this way, the mobile phone can obtain the communication information required by the currently opened positioning application through the communication tag.

[0113] S205. The communication tag determines communication information based on the UWB configuration information and the UWB signal.

[0114] In an embodiment of the present application, when the communication tag receives the UWB configuration information, it can learn the communication requirements of the terminal; thus, the communication tag can obtain the information required by the terminal based on the UWB signal as communication information.

[0115] S206. The communication tag carries the communication information in the communication signal and sends the communication signal to the terminal during the communication time period of the current communication cycle.

[0116] S207. If the terminal detects the NFC radio frequency field of a third-party NFC device during the non-communication time period of the current communication cycle, it sends a communication pause instruction message to the communication tag during the communication time period of the next communication cycle.

[0117] S208. The communication tag responds to the communication pause instruction message and pauses the communication with the terminal within 10 communication cycles after the next communication cycle.

[0118] S209. The terminal establishes a communication connection with the third-party NFC device within 10 communication cycles after the next communication cycle, thereby implementing the NFC function related to the third-party NFC device.

[0119] S210. After 10 communication cycles after the next communication cycle end, the communication tag continues to perform periodic NFC communication with the terminal.

[0120] In an embodiment of the present application, the tag identity information of the communication tag will only be powered on and then operate normally when it matches the terminal. After the communication tag operates normally, it can receive the UWB signal and obtain communication information based on the UWB signal; and, perform NFC communication with the terminal during the communication time period of any communication cycle; if the terminal detects the NFC radio frequency field of a third-party NFC device during the non-communication time period, it can send a communication pause instruction message to the communication tag during the communication time period after the non-communication time period, so that the communication tag pauses the NFC communication with the terminal within 10 communication cycles after the communication time period ends, enabling the terminal to establish a communication connection with the third-party device and perform NFC communication within these 10 communication cycles to implement the NFC function between the terminal and the third-party device; and, after these 10 communication cycles end, the terminal and the communication tag continue to perform periodic NFC communication. That is to say, after the terminal establishes a communication connection with the communication tag, it can still implement the NFC function with the third-party device, improving the flexibility of NFC communication between the terminal and the communication tag.
