Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

At present, taking a bluetooth headset as an example, in order to quickly pair and connect the bluetooth headset and a mobile phone and remind a user of successful connection, manufacturers design their own bluetooth connection popup mechanism. In the related art, generally, when a user opens a lid of a bluetooth headset, the bluetooth headset starts to transmit a broadcast signal to the surroundings, the broadcast signal includes a MAC address of the bluetooth headset, and bluetooth devices around the bluetooth headset can be paired and connected with the bluetooth headset after receiving the broadcast signal. However, when the bluetooth headset sends a broadcast signal to the surroundings, since all devices around the bluetooth headset receive the popup alert of the bluetooth connection, and some of the devices are not target devices to be paired and connected with the bluetooth headset, serious disturbance is caused to the devices. Based on this, the following embodiments of the present application provide a near field communication device connection method, apparatus, near field communication device, computer readable storage medium and computer program product, which can solve the above technical problems.

The near field communication device connection method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein the first near field communication device 102 can perform near field communication connection with other near field communication devices 104. The near field communication connection can be a bluetooth connection, an NFC connection, and the like, and the embodiment of the present application does not limit the near field connection manner.

The first near field communication device 102 may be a headset, a watch, a bracelet, a speaker, etc. Other near field communication devices 104 may be various personal computers, laptops, smart phones, tablets, internet of things devices, and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart car devices, and the like. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, and the like. In addition, the near field communication device 102 and the other near field communication devices 104 may each include an antenna, a speaker, a microphone, a near field communication main control circuit, a battery, and the like, and when the first near field communication device 102 is paired with or connected back to the other near field communication devices 104, the first near field communication device 102 is connected with the other near field communication devices 104 through near field communication signals. It should be noted that the other near field communication devices may include a near field communication device that has been history-paired with the first near field communication device 102 (for convenience of description of the following embodiments, the history-paired near field communication devices are all referred to as a second near field communication device), and may also include a new device that has not been history-paired with the first near field communication device 102.

In one embodiment, as shown in fig. 2, a method for connecting a near field communication device is provided, which is exemplified by the method applied to the first near field communication device in fig. 1, and may include the following steps:

s202, whether the first near field communication equipment triggers the near field communication connection is monitored.

In this step, the first near field communication device may be the first near field communication device 102 in fig. 1, which may be a headset, a watch, a bracelet, a sound box, or the like.

Specifically, the first near field communication device may continuously monitor whether to trigger the near field communication connection process, for example, whether to open the box cover, trigger a power on/off button on the device, input power on/off information, input connection information, or the like, and obtain a monitoring result through monitoring.

Taking this first near field communication equipment to be bluetooth headset as an example, bluetooth headset all can put into the earphone box when not using usually, so when the user need use bluetooth headset and open the bluetooth headset lid, will trigger bluetooth headset's near field communication connection flow, and bluetooth headset just can monitor this moment and has triggered near field communication and connect. The monitoring connection when the first near field communication device is another device may be similar to a bluetooth headset, which is only an example.

And S204, if the first near field communication equipment triggers near field communication connection, the first near field communication equipment sends a plurality of groups of communication broadcast signals to the periphery.

In this step, each group of communication broadcast signals includes a directional broadcast signal and a non-directional broadcast signal, and the transmission power of the directional broadcast signal in the first M groups of communication broadcast signals is greater than the transmission power of the non-directional broadcast signal, the directional broadcast signal is used for connecting paired devices, and the non-directional broadcast signal is used for pairing and connecting unpaired devices, where M is a positive integer greater than or equal to one.

Specifically, the directional broadcast signal includes a Media Access Control (MAC) address of the near field communication device that is pre-paired with the first near field communication device, each directional broadcast signal includes a MAC address of a paired near field communication device, and each group of communication broadcast signals includes a directional broadcast signal, so that a plurality of groups of communication broadcast signals correspond to a plurality of directional broadcast signals, and the MAC address of the paired near field communication device included in each directional broadcast signal may be a MAC address of the same near field communication device or a MAC address of different near field communication devices, which is not specifically limited in this embodiment. The non-directional broadcast signals include the MAC address of the first near field communication device, and each group of communication broadcast signals includes one non-directional broadcast signal, so that there are multiple groups of communication broadcast signals corresponding to multiple/multiple groups of non-directional broadcast signals, and each non-directional broadcast signal includes the MAC address of the first near field communication device.

In addition, when monitoring that the short-range communication connection process is triggered, the first short-range communication device can send multiple groups of communication broadcast signals including directional broadcast signals and non-directional broadcast signals to the periphery. Specifically, when each group of communication broadcast signals is transmitted, the directional broadcast signals may be transmitted first, and then the non-directional broadcast signals may be transmitted, or the non-directional broadcast signals may be transmitted first, and then the directional broadcast signals may be transmitted. In this embodiment, it is preferable to transmit the directional broadcast signal first and then transmit the non-directional broadcast signal, so that the device paired with the first near field communication device can be connected with the first near field communication device more quickly.

Further, when the first near field communication device transmits the directional broadcast signal and the non-directional broadcast signal to the surroundings, the transmission power of the directional broadcast signal is not particularly limited, and may be any transmission power, for example. For example, the transmission power of the directional broadcast signals in the first M groups of communication broadcast signals may be a fixed/same transmission power, assuming that it may be the maximum transmission power of the first near field communication device when transmitting signals; of course, the transmission power of the directional broadcast signals in each group of communication broadcast signals may be different, as long as it can be ensured that the transmission power of the directional broadcast signals in each group of communication broadcast signals is greater than the transmission power of the non-directional broadcast signals, for example, the power of each group of directional broadcast signals may be gradually increased.

Similarly, as for the transmission power of the non-directional broadcast signals, the transmission power of the non-directional broadcast signals in the first M groups of communication broadcast signals may be a fixed/same transmission power, or the transmission powers of the non-directional broadcast signals in the groups of communication broadcast signals may be different, as long as it is ensured that the transmission power of the directional broadcast signals in each group of communication broadcast signals is greater than the transmission power of the non-directional broadcast signals.

In addition, optionally, the transmission power of the directional broadcast signal is equal to the transmission power of the non-directional broadcast signal from the M +1 th group. That is, starting from the group M +1, the transmission power of the non-directional broadcast signal may be increased to be equal to the transmission power of the directional broadcast signal, or both the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal may be increased to be equal to each other, or other cases may be used.

It should be noted that, the transmission power of the signal is larger, the corresponding broadcast distance is longer, and the number of devices existing in the corresponding range is larger, so that the disturbance to the devices is more serious. In the embodiment, the transmission power of the directional broadcast signal is greater than that of the non-directional broadcast signal, so that the back connection efficiency of the first near field communication equipment and the paired equipment can be improved; in addition, when the first near field communication device is connected with the new device, the new device is generally closer to the first near field communication device, so that the new device can receive signals by adopting lower transmitting power of non-directional broadcast signals, and other surrounding users or devices cannot receive the broadcast signals when being far away, so that the quick popup and connection between the new device and the first near field communication device are ensured, and the low disturbance to other users or devices is also ensured.

In addition, the first near field communication device may continuously detect whether the first near field communication device has successfully connected to the peripheral device while transmitting the broadcast signal, and when detecting that the first near field communication device has successfully connected to the peripheral device, the first near field communication device may stop transmitting all broadcast signals to the periphery until a next connection procedure is retriggered or a communication broadcast signal is transmitted, for example, the first near field communication device is a bluetooth headset, and may open a bluetooth headset lid until the next time, so that power consumption of the first near field communication device may be saved.

In the near field communication equipment connection method, whether the first near field communication equipment triggers the near field communication connection or not is monitored, and when the first near field communication equipment triggers the near field communication connection, a plurality of groups of communication broadcast signals are sent to the periphery; each group of communication broadcast signals comprises directional broadcast signals and non-directional broadcast signals, and the transmitting power of the directional broadcast signals in the first M groups of communication broadcast signals is greater than that of the non-directional broadcast signals. In the method, a first near field communication device transmits a directional broadcast signal with larger transmission power and transmits a non-directional broadcast signal with smaller transmission power in the first M groups of communication broadcast signals, because the directional broadcast signal is used for connecting paired devices, the non-directional broadcast signal is used for pairing and connecting unpaired devices, and meanwhile, in most scenes of practical application, the near field communication devices are connected with the paired devices, the first near field communication device can be quickly connected with the paired devices by transmitting the directional broadcast signal with larger power, so that the transmission time of the communication broadcast signal can be reduced, disturbance to other devices can be reduced in the time dimension, on the other hand, in order to ensure the connection efficiency, the scenes that the near field communication device is paired and connected with the unpaired devices are considered, in the method, the first near field communication device can also transmit non-directional broadcast signals, but because the transmission power of the non-directional broadcast signals is small, only devices within a small range can receive the non-directional broadcast signals, and therefore disturbance to other devices can be reduced in the spatial dimension.

In the above embodiments, it is mentioned that the transmission power of each set of the non-directional broadcast power may be the same value or different values, and the following embodiments describe the case where the transmission power of each set of the non-directional broadcast power is different values.

In another embodiment, in each two adjacent groups of communication broadcast signals, the transmission power of the non-directional broadcast signal in the next group of communication broadcast signals is greater than the transmission power of the non-directional broadcast signal in the previous group of communication broadcast signals.

In this embodiment, for the transmission power of the non-directional broadcast signal, the transmission power is gradually increased to perform transmission until the maximum transmission power of the first near-field communication device is increased when the first near-field communication device transmits the signal, and the transmission power of the non-directional broadcast signal is not increased. For example, if there are three times, t1, t2, and t3, which are respectively t1< t2< t3, and each time transmits a group of communication broadcast signals, the transmission power of the non-directional broadcast signal transmitted at time t3 is greater than that of the non-directional broadcast signal transmitted at time t2, and the transmission power of the non-directional broadcast signal transmitted at time t2 is greater than that of the non-directional broadcast signal transmitted at time t 1.

In addition, the step size of the increase of the transmission power of each group of non-directional broadcast signals may be the same step size, or may be different step sizes. When the transmission power of each group of non-directional broadcast signals is gradually increased by adopting different step lengths, for example, the transmission power of each group of non-directional broadcast signals can be increased according to a rule from slow to fast, that is, the step length of the increase of the transmission power of each group of non-directional broadcast signals can be gradually increased, so that the signal attenuation rule is relatively met, the attenuation is faster as the general signal transmission distance is longer, the accuracy of signal transmission can be improved, and the success rate of connection between the surrounding equipment and the first near-distance communication equipment is improved.

In this embodiment, the power of the non-directional broadcast signal is increased step by step, so that the broadcast distance may be increased step by step, starting from the short broadcast distance, and when there is no connected device within the short broadcast distance, the broadcast distance may be increased step by step, so that the surrounding devices may be successfully connected, thereby reducing disturbance to other devices around the first near field communication device while ensuring that the surrounding devices are quickly connected back. In addition, when the first near field communication device is connected with the new device, the new device is generally closer to the first near field communication device, so that the new device can receive signals with lower transmitting power, and other surrounding users or devices are far away and cannot receive broadcast signals, so that quick popup and connection between the new device and the first near field communication device are ensured, and low disturbance to other users or devices is also ensured. Furthermore, the transmission power of the non-directional broadcast signal can be gradually increased, that is, the transmission power of the non-directional broadcast signal can be adjusted from small to large, so that the broadcast distance of the non-directional broadcast signal can be gradually increased, a new device far away from the first near-field communication device can be quickly connected with the first near-field communication device, and the connection success rate between the new device and the first near-field communication device is improved.

In the above embodiment, it is mentioned that the directional broadcast signal includes the MAC address of the paired device, and when the first near field communication device transmits a plurality of sets of communication broadcast signals to the surroundings, it may also be determined in advance whether the paired device is stored therein, and the process will be described in detail below.

In another embodiment, another near field communication device connection method is provided, and on the basis of the above embodiment, the above S204 may include the following steps:

step A, if a second near field communication device which is historically paired with the first near field communication device is stored in the first near field communication device, the first near field communication device sends a plurality of groups of communication broadcast signals to the periphery, wherein the directional broadcast signals in each group of communication broadcast signals correspond to the second near field communication device.

In this step, it may be determined in advance whether or not a second near field communication device that has been historically paired with the first near field communication device is stored in the first near field communication device, and generally, when the first near field communication device is paired with the second near field communication device, the MAC address of the second near field communication device is stored in the memory of the first near field communication device. Here, generally, the memory of the first near field communication device can store the latest N devices (N ≧ 1), all the stored devices can be referred to as the second near field communication devices, and the size of N can be set according to the actual situation, and can be, for example, 5, 6, 10, and so on.

Since the memory of the first near field communication device can store the historically paired MAC address of the second near field communication device, it can be determined whether the memory of the first near field communication device has the MAC address of the second near field communication device, and when the memory of the first near field communication device has the MAC address of the second near field communication device, it is characterized that the first near field communication device has been paired with other near field communication devices before, and the devices can be preferentially paired.

Further, when the first near field communication device transmits a plurality of groups of communication broadcast signals to the surroundings, the directional broadcast signal in each group of communication broadcast signals corresponds to each second near field communication device, that is, the MAC address included in each directional broadcast signal is the MAC address of the second near field communication device. Here, each directional broadcast signal may include a different MAC address of the second near field communication device, or each m adjacent directional broadcast signals may include a same MAC address of the second near field communication device, where m may be 2, 3, 4, and so on.

In addition, optionally, if the first near field communication device does not store the second near field communication device, in this case, the first near field communication device may transmit a plurality of sets of non-directional broadcast signals to the surroundings. That is to say, when the paired second near field communication device is not stored in the first near field communication device, it is considered that the first near field communication device needs to connect to a new near field communication device, and at this time, the first near field communication device always sends a non-directional broadcast signal to the surroundings, which can facilitate the surrounding devices to quickly obtain the MAC address of the first near field communication device so as to connect to the first near field communication device. Further, in order to reduce disturbance to the devices around the first near field communication device, the transmission power of the non-directional broadcast signals may also be gradually increased to perform transmission, that is, when the first near field communication device transmits multiple sets of non-directional broadcast signals to the surroundings, the transmission power of the next set of non-directional broadcast signals is greater than the transmission power of the previous set of non-directional broadcast signals in every two adjacent sets of non-directional broadcast signals.

In this embodiment, when there is a history paired device in the first near field communication device, multiple groups of communication broadcast signals may be sent to the surroundings, so that the device history paired with the first near field communication device may be conveniently and quickly connected back to the first near field communication device, and simultaneously, disturbance to other surrounding devices may be reduced. In addition, when no history paired equipment exists in the first near field communication equipment, a plurality of groups of non-directional broadcast signals can be sent to the periphery, so that the first near field communication equipment can be quickly connected with the surrounding new equipment, and the connection time of the first near field communication equipment and the new equipment is shortened.

In the above embodiments, it is mentioned that the MAC address of the paired device may be saved in the first near field communication device, and then the directional broadcast signal including the MAC address of the paired device may be sent to the surroundings.

In another embodiment, there is provided another near field communication device connection method, and on the basis of the foregoing embodiment, as shown in fig. 3, the foregoing S204 may include the following steps:

s302, the first near field communication device determines the connection priority of each second near field communication device.

In this step, at least two second near field communication devices are stored in the first near field communication device, and at the same time, the time for each second near field communication device to perform historical pairing with the first near field communication device may be stored in the first near field communication device. Here, the closer the historical pairing time of the second near field communication device and the first near field communication device is to the current time, the higher the corresponding connection priority, that is, the highest connection priority of the second near field communication device that has been paired with the first near field communication device last. Therefore, the connection priority corresponding to each second near field communication device can be obtained through the historical pairing time of each second near field communication device and the first near field communication device.

S304, the first near field communication device sends a plurality of groups of communication broadcast signals to the periphery according to the connection priority of each second near field communication device.

In this step, after obtaining the connection priority of each second near field communication device, the MAC address of each second near field communication device may be inserted into each group of directional broadcast signals in sequence from high to low according to the connection priority of each second near field communication device, so as to obtain and broadcast a plurality of groups of communication broadcast signals. That is, the MAC address of the second near field communication apparatus having the highest connection priority can be preferentially broadcast here, so that the probability that the second near field communication apparatus succeeds in the reconnection with the first near field communication apparatus can be increased.

In this embodiment, the first near field communication device sends multiple groups of communication broadcast signals to the surroundings according to the determined connection priority of each second near field communication device, so that multiple groups of communication broadcast signals can be sent to the surroundings in a targeted manner, and the accuracy and efficiency of sending the communication broadcast signals are improved. Furthermore, the connection priority of each second near field communication device can be determined through the historical pairing time of the first near field communication device and each second near field communication device, so that the connection priority of each second near field communication device can be determined quickly and accurately, the time for setting each group of communication broadcast signals is shortened, and the accuracy and the efficiency of sending the communication broadcast signals are further improved.

The above-mentioned embodiments mention that a plurality of sets of communication broadcast signals each including a directional broadcast signal and a non-directional broadcast signal can be transmitted to the surroundings in the first near field communication apparatus, and the following embodiments describe in detail how the plurality of sets of communication broadcast signals can be transmitted, without specifically referring to the manner of how the plurality of sets of communication broadcast signals are transmitted.

and step B, the first near field communication equipment sends every two adjacent groups of communication broadcast signals at intervals of a first preset time length.

In this step, referring to fig. 4, the first near field communication apparatus may intermittently transmit a plurality of sets of communication broadcast signals to the surroundings, wherein the directional broadcast signal and the non-directional broadcast signal in each set of communication broadcast signals may be transmitted continuously, i.e., without a time interval. Every two adjacent groups of communication broadcast signals can be sent at intervals of a first preset time length, the first preset time lengths between every two adjacent groups of communication broadcast signals can be the same or different, and the size of the first preset time length can be set according to actual conditions, and can be 0s, 0.2s, 0.5s and the like, for example.

In fig. 4, the maximum transmission power when the first near-field communication device transmits a signal may be denoted as Pmax, where the transmission power of each group of directional broadcast signals may be the same, and may be exemplified as a maximum transmission power Pmax, and the transmission power of each group of non-directional broadcast signals may be sequentially increased from P1 to P2, P3, and P4. By gradually increasing the transmit power of the non-directional broadcast signal, this minimizes disturbance to devices surrounding the first near field communication device.

In this embodiment, the first near field communication device may send every two adjacent sets of communication broadcast signals at an interval of a first preset duration, so that devices around the first near field communication device may quickly establish connection with the first near field communication device, and meanwhile, scanning of surrounding devices and power consumption of the first near field communication device may be reduced.

In another embodiment, the first near field communication device sequentially transmits the directional broadcast signal and the non-directional broadcast signal in each group of communication broadcast signals to the surrounding.

That is to say, when the first near field communication device sends each group of communication broadcast signals, the first near field communication device sends the directional broadcast signals first and then sends the non-directional broadcast signals, so that the first near field communication device can be connected with the paired device preferentially, and the connection back efficiency of the first near field communication device and the paired device is improved.

While the above embodiments mention that the first near field communication device can transmit the sets of directional broadcast signals at any transmission power, the following embodiments give two possible implementations of the transmission power of the first near field communication device.

In one possible implementation, the transmission power of the directional broadcast signal in each set of communication broadcast signals is greater than the target transmission power threshold. The target transmission power threshold may be set according to actual conditions, and may be, for example, the maximum transmission power when the first near field communication device transmits a signal, or may be 90% of the maximum transmission power when the first near field communication device transmits a signal.

In this possible implementation, optionally, the transmission power of the directional broadcast signal in each group of communication broadcast signals is the maximum transmission power of the first near field communication device when transmitting the signal. That is, the transmission power of the directional broadcast signal in each group of communication broadcast signals is the same and is the maximum transmission power of the first near field communication device when transmitting the signal, which facilitates the first near field communication device to quickly set each group of directional broadcast signals and facilitates the paired devices around the first near field communication device to quickly connect back to the first near field communication device.

In another possible implementation, in every two adjacent groups of communication broadcast signals, the transmission power of the directional broadcast signal in the latter group of communication broadcast signals is greater than the transmission power of the directional broadcast signal in the former group of communication broadcast signals.

In this possible embodiment, each group of directional broadcast signals may be broadcast to the surroundings by gradually increasing the transmission power until the maximum transmission power of the first near field communication device is increased when transmitting the signals, and the transmission power of the directional broadcast signals is not increased any more. In an actual near field communication device connection scenario, generally, when a user uses a first near field communication device, the first near field communication device is usually located at a position close to a peripheral device, so that the user can connect with the peripheral device without too high transmission power.

In the above embodiments, it is mentioned that the first near field communication device can transmit a plurality of sets of communication broadcast signals to the surroundings, and the case of when to stop transmission is not mentioned, and the following embodiments will explain the process in detail.

In another embodiment, another near field communication device connection method is provided, and on the basis of the above embodiment, as shown in fig. 5, the method may further include the following steps:

and S502, if the signal stop sending condition is met, the first short-distance communication equipment stops sending the communication broadcast signal.

In this step, the first near field communication device may continuously monitor whether a signal stop transmission condition is satisfied while transmitting the communication broadcast signal, and optionally, the signal stop transmission condition may include at least one of the following: the time length of the first near field communication equipment for sending the communication broadcast signal is longer than a second preset time length; the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal are both equal to the maximum transmission power of the first near field communication equipment when the first near field communication equipment transmits the signals.

First, a first case will be described here, in which the above-described case in which the first short-range communication apparatus transmits a communication broadcast signal for a period of time longer than a second preset period of time will be described. Specifically, the first near field communication device may continuously detect whether a duration for the first near field communication device to send the communication broadcast signal is greater than a second preset duration; and if the time length of the first near field communication equipment for sending the communication broadcast signals is longer than a second preset time length, the first near field communication equipment stops sending the communication broadcast signals.

The second preset time period may be set according to actual conditions, and may be, for example, 5s, 10s, and so on. It should be noted that, here, the size of the second preset time period is larger than the time period for increasing the transmission power of the non-directional broadcast signal from P1 to Pmax. That is, after the transmission power of the non-directional broadcast signal is increased from P1 to Pmax, several sets of non-directional broadcast signals are continuously transmitted to the surroundings at Pmax.

Specifically, when the first near field communication device starts to send multiple groups of communication broadcast signals to the surroundings, the time length for sending the multiple groups of communication broadcast signals can be counted, the counted time length is compared with a second preset time length, whether the counted time length is greater than the second preset time length or not is judged, and a judgment result is obtained. When the counted time length of the first near field communication device is longer than a second preset time length, the fact that the first near field communication device is not successfully connected with other devices for a long time is represented, and then the sending of the communication broadcast signals can be stopped, so that the power consumption of the first near field communication device is saved.

Next, a second case will be described here, in which the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal are both equal to the maximum transmission power of the first near-field communication apparatus at the time of transmitting the signal.

In this case, the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal in each group of communication broadcast signals may be gradually increased, so that when the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal are both increased to the maximum transmission power of the first near field communication device during signal transmission, it indicates that there is no near field communication device that can be connected around the first near field communication device, and therefore, in order to save power consumption of the first near field communication device, the first near field communication device may stop transmitting the communication broadcast signals.

In this embodiment, when the duration that the first near field communication device sends the communication broadcast signal is longer than the second preset duration, or when the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal are both equal to the maximum transmission power of the first near field communication device when the first near field communication device sends the signal, the first near field communication device may stop sending the communication broadcast signal, so that the power consumption of the first near field communication device may be saved.

S603, the first near field communication device intermittently sends the directional broadcast signals and the non-directional broadcast signals to the periphery, and the transmitting power of the non-directional broadcast signals is gradually increased.

S604, the first near field communication device sends a plurality of groups of non-directional broadcast signals to the periphery, and the transmitting power of the non-directional broadcast signals is gradually increased.

And S605, the first near field communication device judges whether the existing device is successfully connected, if so, S606 is executed, and if not, S607 is executed.

S606, the first near field communication equipment stops sending the communication broadcast signal.

S607, the first near field communication device detects whether a duration of sending the communication broadcast signal is longer than a second preset duration, or the first near field communication device detects whether the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal are both equal to the maximum transmission power of the first near field communication device when transmitting the signal, if yes, S606 is executed, otherwise, S608 is executed.

And S608, the first near field communication device continues to transmit the directional broadcast signals and the non-directional broadcast signals to the periphery.
