Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only 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, each manufacturer designs a bluetooth connection popup window mechanism. In the related art, generally, when a user opens a cover of a bluetooth headset, the bluetooth headset starts to send a broadcast signal to the surrounding, wherein the broadcast signal includes an MAC address of the bluetooth headset, and bluetooth devices around the bluetooth headset can be paired with the bluetooth headset after receiving the broadcast signal. However, when the bluetooth headset transmits a broadcast signal to the surroundings, since all devices around the bluetooth headset receive the popup window alert of the bluetooth connection, some of the devices are not target devices to be paired by the bluetooth headset, and thus, serious disturbance may be 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 method for connecting the near field communication device, provided by the embodiment of the application, can be applied to an application environment shown in fig. 1. The first near field communication device 102 may be connected to other near field communication devices 104 in a near field communication manner. The close range communication connection may be bluetooth connection, NFC connection, or the like, and the embodiment of the present application does not limit a manner of close range connection.

The first near field communication device 102 may be a headset, a wristwatch, a bracelet, a speaker, etc. Other near field communication devices 104 may be various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. In addition, each of the near field communication devices 102 and 104 may 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 device 104, the first near field communication device 102 and the other near field communication device 104 are connected by near field communication signals. The other short-range communication devices may include a short-range communication device that has been history-paired with the first short-range communication device 102 (for convenience of description of the embodiments described below, the short-range communication devices that have been history-paired are all referred to as second short-range communication devices), and may include a new device that has not been history-paired with the first short-range communication device 102.

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

s202, monitoring whether the first near field communication device triggers a near field communication connection.

In this step, the first near field communication device may be the first near field communication device 102 in fig. 1 described above, which may be an earphone, a wristwatch, a bracelet, a sound box, or the like.

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

Taking this first close range communication equipment as an example of bluetooth headset, bluetooth headset can all put into the earphone box when not using generally, then when the user need use bluetooth headset and open bluetooth headset lid, will trigger bluetooth headset's close range communication connection flow, and bluetooth headset just can monitor the close range communication connection that has triggered this moment. The monitoring connection mode when the first near field communication device is other devices can be similar to that of a bluetooth headset, and only an example is given here.

S204, if the first near field communication device triggers a near field communication connection, the first near field communication device transmits a plurality of sets of communication broadcast signals to the surrounding.

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, where the directional broadcast signal is used to connect to a paired device, and the non-directional broadcast signal is used to pair to connect to an unpaired device, where M is a positive integer greater than or equal to one.

Specifically, the directional broadcast signals include MAC (Media Access Control ) addresses of the close-range communication devices that are paired with the first close-range communication device in advance, each directional broadcast signal includes a MAC address of the paired close-range communication device, and each group of communication broadcast signals includes one directional broadcast signal, so that the multiple groups of communication broadcast signals correspond to multiple directional broadcast signals, and the MAC address of the paired close-range communication device included in each directional broadcast signal may be a MAC address of the same close-range communication device or may be a MAC address of a different close-range communication device, 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 the plurality of groups of communication broadcast signals correspond to a plurality of/a plurality of 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, the first near field communication device may transmit a plurality of sets of communication broadcast signals including a directional broadcast signal and a non-directional broadcast signal to the surroundings when it detects that the near field communication connection flow is triggered. 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 to 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 for example, the first near field communication device may transmit at any transmission power. 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, which may be assumed to 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, so long as the transmission power of the directional broadcast signals in each group of communication broadcast signals can be ensured to be 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.

Likewise, 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 may be different from the transmission power of the non-directional broadcast signals in each group of communication broadcast signals, so long as the transmission power of the directional broadcast signals in each group of communication broadcast signals can be ensured to be greater than the transmission power of the non-directional broadcast signals.

In addition, optionally, the transmission power of the directional broadcast signal from the m+1th group is equal to the transmission power of the non-directional broadcast signal. That is, starting from the m+1th group, 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 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, which may be the case.

It should be noted that, the broadcast distances corresponding to different transmission powers of the signals are different, the larger the transmission power of the signals is, the farther the corresponding broadcast distance is, the more devices exist in the corresponding range, and the more disturbance is caused to the devices. In the embodiment, the transmission power of the directional broadcast signal is larger than that of the non-directional broadcast signal, so that the reconnection efficiency of the first near field communication device and the paired device can be improved; in addition, when the first near field communication device is connected with the new device, the new device and the first near field communication device are generally close to each other, so that the new device can receive the signal by adopting lower transmitting power of the non-directional broadcast signal, and other surrounding users or devices can not receive the broadcast signal at a longer distance, thereby ensuring quick popup and connection between the new device and the first near field communication device and ensuring low harassment to other users or devices.

In addition, the first near field communication device may continuously detect whether the connection between the first near field communication device and the surrounding device is successful while sending the broadcast signal, and when the connection between the first near field communication device and the surrounding device is detected to be successful, the first near field communication device may stop sending all broadcast signals to the surrounding until the next time to re-trigger the connection flow or send the communication broadcast signal, for example, the first near field communication device is a bluetooth headset, and may be a bluetooth headset cover or the like until the next time to re-open, so that the power consumption of the first near field communication device may be saved.

In the above-mentioned short-range communication device connection method, by monitoring whether the first short-range communication device triggers a short-range communication connection, and when the first short-range communication device triggers a short-range communication connection, sending a plurality of groups of communication broadcast signals to the surroundings; wherein 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. In the method, the first near field communication device transmits a directional broadcast signal with larger transmission power and transmits an unoriented broadcast signal with smaller transmission power in the first M groups of communication broadcast signals, and the directional broadcast signal is used for connecting paired devices, so that the first near field communication device can be quickly connected with the paired devices by transmitting the directional broadcast signal with larger power in most of practical scenes, the transmission duration of the communication broadcast signal can be reduced, and the disturbance to other devices can be reduced in the time dimension, on the other hand, in order to ensure the connection efficiency, the first near field communication device can also transmit the unoriented broadcast signal, but only devices in a smaller range can receive the unoriented broadcast signal due to smaller transmission power of the unoriented broadcast signal, so that the disturbance to other devices can be reduced in the space dimension.

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

In another embodiment, 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 every two adjacent groups of communication broadcast signals.

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

In addition, the step of increasing the transmission power of each group of non-directional broadcast signals may be performed in a stepwise manner by using the same step, or may be performed in a stepwise manner by using different steps. When the transmission power of each group of non-directional broadcasting signals is gradually increased by adopting different step sizes, for example, the step sizes of the increase of the transmission power of each group of non-directional broadcasting signals can be gradually increased according to a law from slow to fast, so that the comparison accords with a signal attenuation law, the longer the general signal transmission distance is, the faster the attenuation is, the accuracy of signal transmission can be improved, and the success rate of connection of surrounding equipment and first near-field communication equipment is improved.

In this embodiment, the power of the non-directional broadcast signal is gradually increased, so that the broadcast distance is gradually increased, and when there is no connected device in the short broadcast distance, the broadcast distance is gradually increased, so that the surrounding devices can be successfully connected, and the disturbance to other devices around the first near field communication device can be reduced while the surrounding devices are ensured to be quickly connected back. In addition, when the first near field communication device is connected with the new device, the new device and the first near field communication device are generally close to each other, so that the new device can receive signals by adopting lower transmitting power, and other surrounding users or devices can not receive broadcast signals due to longer distance, thereby ensuring quick popup and connection between the new device and the first near field communication device and ensuring low harassment to other users or devices. Further, since the transmitting power of the non-directional broadcasting signal can be gradually increased, that is, the transmitting power of the non-directional broadcasting signal can be adjusted from small to large, the broadcasting distance of the non-directional broadcasting signal can be gradually enlarged, so that the new device far away from the first near field communication device can be quickly connected with the first near field communication device, and the success rate of connection between the new device and the first near field communication device is improved.

In the above embodiment, when the directional broadcast signal includes the MAC address of the paired device, it may be further determined in advance whether the paired device is stored when the first short-range communication device transmits the plurality of sets of communication broadcast signals to the surroundings, and this will be described in detail below.

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

and step A, if the first near field communication device stores a second near field communication device which is historically paired with the first near field communication device, the first near field communication device transmits a plurality of groups of communication broadcast signals to the surrounding, wherein the directional broadcast signals in the groups of communication broadcast signals correspond to the second near field communication device.

In this step, it may be determined in advance whether or not the first short-range communication device has stored therein a second short-range communication device for which the first short-range communication device has been subjected to history pairing, and generally, when the first short-range communication device has been paired with the second short-range communication device, the MAC address of the second short-range communication device is stored in the memory of the first short-range communication device. In general, the memory of the first near field communication device may store the latest N devices (N is greater than or equal to 1), where the stored devices may be denoted as the second near field communication device, and the size of N may be set according to the actual situation, for example, may be 5, 6, 10, etc.

Since the memory of the first close-range communication device stores the MAC address of the second close-range communication device paired in history, by judging whether the memory of the first close-range communication device has the MAC address of the second close-range communication device, when the memory of the first close-range communication device has the MAC address of the second close-range communication device, the first close-range communication device is characterized as being paired with other close-range communication devices before, the first close-range communication device can be preferentially paired, so that multiple groups of communication broadcast signals including directional broadcast signals and non-directional broadcast signals can be sent to the surrounding, and the first close-range communication device can be quickly connected back to the surrounding paired devices.

Further, when the first near field communication device transmits a plurality of sets of communication broadcast signals to the surroundings, wherein the directional broadcast signals in each set of communication broadcast signals correspond to the respective second near field communication devices, 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 MAC address of a different second near field communication device, or each m adjacent directional broadcast signals may include a MAC address of the same second near field communication device, where m may be 2, 3, 4, and so on.

Further alternatively, if the second near field communication device is not stored in the first 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, 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 be connected to a new near field communication device, and the first near field communication device always transmits a non-directional broadcast signal to the surroundings, so that the surrounding devices can quickly obtain the MAC address of the first near field communication device to connect with the first near field communication device. Further, in order to reduce disturbance to devices around the first near field communication device, the transmission power of the non-directional broadcast signal may also be transmitted in a manner of gradually increasing the transmission power, that is, when the first near field communication device transmits multiple sets of non-directional broadcast signals to the surrounding, the transmission power of the latter set of non-directional broadcast signals is greater than the transmission power of the former set of non-directional broadcast signals in every two adjacent sets of non-directional broadcast signals.

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

In the above-described embodiments, it is mentioned that the MAC address of the paired device may be stored in the first near field communication device, and then a directional broadcast signal including the MAC address of the paired device may be transmitted to the surroundings, and the following embodiments describe in detail how to transmit the directional broadcast signal.

In another embodiment, another method for connecting a near field communication device is provided, and based on the above embodiment, as shown in fig. 3, the step S204 may include the following steps:

s302, the first near field communication device determines 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 of performing history pairing between each second near field communication device and the first near field communication device may be stored in the first near field communication device, so that optionally, the first near field communication device may determine the connection priority of each second near field communication device according to the history pairing time between each second near field communication device and the first near field communication device. The closer the historical pairing time of the second near-field communication device and the first near-field communication device is to the current moment, the higher the corresponding connection priority is, namely the highest connection priority of the second near-field communication device which is paired with the first near-field communication device last. Thus, by the historic pairing time of each second near field communication device and the first near field communication device, the connection priority corresponding to each second near field communication device can be obtained.

S304, the first near field communication device transmits a plurality of sets of communication broadcast signals to the surroundings according to the connection priority of each second near field communication device.

In this step, after the connection priority of each second near field communication device is obtained, the MAC address of each second near field communication device may be sequentially inserted into each group of directional broadcast signals 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, here, the MAC address of the second near field communication device having the highest connection priority can be preferentially broadcast, so that the probability of the second near field communication device becoming successful in connection with the first near field communication device can be increased.

In this embodiment, the first near field communication device sends multiple groups of communication broadcast signals to the surrounding 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 surrounding in a targeted manner, and the accuracy and efficiency of sending the communication broadcast signals are improved. Further, the connection priority of each second short-range communication device can be determined through the historical pairing time of the first short-range communication device and each second short-range communication device, so that the connection priority of each second short-range communication device can be rapidly and accurately determined, the time for setting each group of communication broadcast signals is shortened, and the accuracy and the efficiency of communication broadcast signal transmission are further improved.

In the above-described embodiments, the first near field communication device may transmit, to the surrounding, a plurality of sets of communication broadcast signals each including a directional broadcast signal and a non-directional broadcast signal, and the manner of how to transmit the plurality of sets of communication broadcast signals is not specifically referred to, and the following embodiments describe in detail how to transmit the plurality of sets of communication broadcast signals.

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

In this step, as shown in fig. 4, the first near field communication device may intermittently transmit a plurality of sets of communication broadcast signals to the surroundings, wherein the directional broadcast signals and the non-directional broadcast signals in each set of communication broadcast signals may be continuously transmitted, i.e., there is no time interval to transmit. The first preset time length 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, for example, can be 0s, 0.2s, 0.5s and the like.

In fig. 4, the maximum transmission power at which the first near field communication device transmits signals may be denoted as Pmax, where the transmission power of each set of directional broadcast signals may be the same, and may be exemplified as the maximum transmission power Pmax, and the transmission power of each set of non-directional broadcast signals may be sequentially increased from P1 to P2, P3, P4, until Pmax, where P1< P2< P3< … < Pmax. By gradually increasing the transmission power of the non-directional broadcast signal, it is possible to minimize disturbance to equipment surrounding the first near field communication device.

In this embodiment, the first near-field communication device may send every two adjacent groups of communication broadcast signals at intervals of a first preset duration, so that devices around the first near-field communication device may be conveniently and quickly connected to 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, when each group of communication broadcast signals is transmitted, the first near-field communication device transmits the directional broadcast signals first and then transmits the non-directional broadcast signals, so that the first near-field communication device can be conveniently connected with the paired device preferentially, and the reconnection efficiency of the first near-field communication device and the paired device is improved.

The above embodiments refer to that the first near field communication device may transmit the directional broadcast signals of each group at any transmission power, and the following embodiments provide two possible implementations of the transmission power of the first near field communication device.

In one possible implementation, the transmit power of the directional broadcast signal in each set of communication broadcast signals is greater than a target transmit power threshold. The target transmission power threshold may be set according to the actual situation, and may be, for example, a 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, or the like.

In this possible embodiment, optionally, the transmission power of the directional broadcast signal in each set of communication broadcast signals is the maximum transmission power of the first near field communication device when transmitting the signals. That is, the transmission power of the directional broadcast signals 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 signals, so that the first near-field communication device can conveniently and quickly set each group of directional broadcast signals, and paired devices around the first near-field communication device can conveniently and quickly connect back to the first near-field communication device.

In another possible embodiment, in each two adjacent sets of communication broadcast signals, the transmission power of the directional broadcast signal in the latter set of communication broadcast signals is greater than the transmission power of the directional broadcast signal in the former set of communication broadcast signals.

In this possible embodiment, each set of directional broadcast signals may also be broadcast to the surroundings in a gradually increasing transmission power, until the maximum transmission power of the first near field communication device when transmitting signals is increased, so that the transmission power of the directional broadcast signals is not increased any more. Here, in the actual short-range communication device connection scenario, the user is generally located closer to the surrounding devices when using the first short-range communication device, so that the connection with the surrounding devices can be performed without too high transmission power, and directional broadcasting can also be performed by gradually increasing the transmission power instead of using a fixed maximum transmission power, so that the power consumption of the first short-range communication device when transmitting communication broadcast signals of each group can be reduced.

The above-described embodiment has mentioned that the first near field communication device can transmit a plurality of sets of communication broadcast signals to the surroundings, and the case when transmission is stopped is not mentioned, and the following embodiment will explain the procedure in detail.

In another embodiment, another method for connecting a near field communication device is provided, and based on the above embodiment, as shown in fig. 5, the method may further include the following steps:

s502, if the signal stop transmission condition is satisfied, the first short-range communication apparatus stops transmitting 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 device for sending the communication broadcast signal is longer than a second preset time length; the transmitting power of the directional broadcasting signal and the transmitting power of the non-directional broadcasting signal are equal to the maximum transmitting power of the first near field communication device when transmitting the signals.

First, a first case will be described herein, in which the first short-range communication device transmits a communication broadcast signal for a time period longer than a second preset time period. Specifically, the first near field communication device continuously detects whether the duration of sending the communication broadcast signal by the first near field communication device is longer than a second preset duration; and if the time period of the communication broadcasting signal sent by the first short-range communication equipment is longer than the second preset time period, stopping sending the communication broadcasting signal by the first short-range communication equipment.

The second preset duration may be set according to practical situations, for example, may be 5s, 10s, and so on. It should be noted that, the second preset duration is greater than a duration during which the transmission power of the non-directional broadcast signal increases from P1 to Pmax. That is, here, after the transmission power of the non-directional broadcast signal is increased from P1 to Pmax, several sets of non-directional broadcast signals are further transmitted to the surroundings with the transmission power of Pmax.

Specifically, when the first near field communication device starts to send multiple groups of communication broadcast signals to the surrounding, the duration of sending the multiple groups of communication broadcast signals can be counted, the counted duration is compared with a second preset duration, whether the counted duration is greater than the second preset duration or not is judged, and a judgment result is obtained. When the counted time length of the first short-distance communication equipment is longer than the second preset time length, the first short-distance communication equipment is characterized to be not successfully connected with other equipment for a long time, and the transmission of communication broadcasting signals can be stopped, so that the power consumption of the first short-distance communication equipment is saved.

Next, a description will be given here of a second case where the transmission power of the above-described 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.

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 both the transmission power of the directional broadcast signal and the transmission power of the non-directional broadcast signal are increased to the maximum transmission power of the first near field communication device when transmitting the signals, it is indicated that there is no near field communication device around the first near field communication device that can be connected, so that the first near field communication device may stop transmitting the communication broadcast signal at this time in order to save power consumption of the first near field communication device.

In this embodiment, when the time period for the first near field communication device to transmit the communication broadcast signal is longer than the second preset time period, 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 transmitting the signal, the first near field communication device may stop transmitting the communication broadcast signal, so that the power consumption of the first near field communication device may be saved.
