The bluetooth headset may also be connected to 3 or 4 or even more devices and perform transmission of bluetooth traffic.

The historical connection device is a device which is successfully connected with the Bluetooth headset, such as a mobile phone, a tablet and the like.

When the Bluetooth service is music playing, the service data is music data. When the Bluetooth service is video playing, the service data is video data.

When the Bluetooth headset and the historical connection equipment perform Bluetooth service transmission, the Bluetooth headset can record the transmission condition of service data. The transmission condition of the service data may include a start time of service data transmission, an end time of service data transmission, a duration of service data transmission, a number of times of service data transmission, a type of service data, and the like.

The bluetooth headset may determine a backhaul sequence of the plurality of historical connection devices according to a service data transmission condition of each of the plurality of historical connection devices. That is to say, when the bluetooth headset is in the headset box and the headset box is in an open state, the bluetooth headset is connected with M historical connected devices, where M is an integer greater than 1, and the connection order of the M historical connected devices is associated with the historical service data transmission situations of the M historical connected devices.

In another possible implementation manner, in the case that the bluetooth headset performs bluetooth service transmission with each historically connected device, the bluetooth dual-connected headset may record the time when each historically connected device transmits the service and update the time in real time, that is, only one time is recorded for one device, and the time is updated in real time according to the transmission of the service. When the bluetooth headset is disconnected from each historical connected device, the bluetooth headset may determine the recorded time when each historical connected device transmits the service as the last time when each historical connected device transmits the service.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The Bluetooth dual connection earphone can be connected with two devices simultaneously, the default first paired device is used for preferential communication, and when no signal is transmitted to the Bluetooth dual connection earphone by the first paired device, the Bluetooth dual connection earphone can receive the signal transmitted by the second paired device. The bluetooth dual connectivity headset may enable receiving signals transmitted by a second paired device when a first paired device is connected.

When the Bluetooth dual connection earphone is in the earphone box and the earphone box is in a closed state, the Bluetooth dual connection earphone is disconnected with the two devices respectively. When the Bluetooth dual connection earphone is in the earphone box and the earphone box is in an open state, the Bluetooth dual connection earphone is reconnected with the two devices respectively, namely Bluetooth reconnection is carried out.

Illustratively, fig. 1 shows a scenario diagram of a communication system 100. As shown in fig. 1, the communication system 100 includes a bluetooth dual connection headset 101, a handset 102, and a tablet 103. The mobile phone 102 and the tablet 103 establish bluetooth connection with the bluetooth dual-connection headset 101 respectively. The mobile phone 102 may be a first device paired with the bluetooth dual-connection headset 101, the tablet 103 may be a second device paired with the bluetooth dual-connection headset 101, and when no signal is transmitted to the bluetooth dual-connection headset 101 from the mobile phone 102, the bluetooth dual-connection headset 101 may play a signal transmitted by the tablet 103.

Fig. 2 shows a diagram of a bluetooth dual-connection headset 101 loop-back. As shown in a of fig. 2, if the bluetooth dual connection earphone 101 is in the earphone box and the earphone box is in the closed state, the bluetooth dual connection earphone 101 is disconnected from the mobile phone 102 and the flat plate 103, respectively. As shown in the interface b in fig. 2, when the bluetooth dual-connection headset 101 is in the headset box and the headset box is in an open state, the bluetooth dual-connection headset 101 may send a connection signal back to the mobile phone 102 or the tablet 103.

Currently, the device that the bluetooth dual-connection headset preferentially reconnects is the last disconnected device, wherein the last disconnected device may be simply referred to as the last disconnected device.

Illustratively, in the example shown in fig. 2 above, the bluetooth dual connectivity headset 101 determines the last disconnected device from the handset 102 and the pad 103 and sends a connect signal back thereto.

In particular, fig. 3 shows a schematic flow diagram of a bluetooth headset reconnection method 300. As shown in fig. 3, the method 300 may include the steps of:

s301, the Bluetooth dual-connection earphone 101 records the disconnection time of the mobile phone 102 and the disconnection time of the tablet 103.

When the bluetooth dual-connection earphone 101 is in the earphone box and the earphone box is in a closed state, the bluetooth dual-connection earphone 101 is disconnected from the mobile phone 102 and the tablet 103, and the bluetooth dual-connection earphone 101 records the disconnection time of the mobile phone 102 and the disconnection time of the tablet 103.

It should be noted that the mobile phone 102 and the tablet 103 are sequentially disconnected from the bluetooth dual-connection headset 101, and there is no case of simultaneous disconnection.

S302, the Bluetooth double-connection earphone 101 determines the last disconnected equipment according to the disconnection time of the mobile phone 102 and the disconnection time of the tablet 103.

If the disconnection time of the mobile phone 102 is later than the disconnection time of the tablet 103, the last disconnected device is the mobile phone 102. If the disconnection time of the tablet 103 is later than the disconnection time of the mobile phone 102, the last disconnected device is the tablet 103.

And S303, if the last disconnected device is the panel 103, sending a connection signal back to the panel 103.

The last disconnected device is the tablet 103, that is, the time when the tablet 103 is disconnected is later than the time when the mobile phone 102 is disconnected, the bluetooth dual-connection headset 101 may preferentially send a connection signal back to the tablet 103.

S304, judging whether the Bluetooth double-connection earphone 101 and the tablet 103 are successfully connected.

If the bluetooth dual-connectivity headset 101 receives the feedback signal from the tablet 103, it may indicate that the loopback connection is successful. If the bluetooth dual-connection headset 101 does not receive the feedback signal of the tablet 103, it may indicate that the connection back is unsuccessful.

If the bluetooth dual-connection headset 101 and the tablet 103 are successfully connected back, S305 is executed, and if the bluetooth dual-connection headset 101 and the tablet 103 are not successfully connected back, S306 is executed.

S305, if the bluetooth dual connection earphone 101 and the tablet 103 are successfully connected, sending a connection signal back to the mobile phone 102.

After the bluetooth dual-connection headset 101 successfully connects back with the tablet 103, the bluetooth dual-connection headset can continuously send back a connection signal to the mobile phone 102. If the bluetooth dual connection earphone 101 and the mobile phone 102 are successfully connected back, the bluetooth dual connection earphone 101 realizes dual connection.

And S306, if the Bluetooth dual-connection earphone 101 is not successfully connected with the tablet 103, continuously sending a connection signal back to the tablet 103 within a fixed time.

If the first reconnection is unsuccessful, the bluetooth dual-connection headset 101 may continue to send a connection signal back to the tablet 103 until a fixed duration is reached or the reconnection is successful. The fixed time period may be 15 seconds, but the embodiment of the present application is not limited thereto.

And S307, if the reconnection is still unsuccessful after the fixed time length is exceeded, sending a connection signal back to the mobile phone 102.

If the fixed time length is exceeded and the bluetooth dual-connection earphone 101 and the tablet 103 are still unsuccessfully connected back, the bluetooth dual-connection earphone 101 sends back a connection signal to the mobile phone 102.

It can be known from the above process that the bluetooth dual-connection earphone 101 preferentially reconnects the device tablet 103 disconnected last, if the user opens the earphone box, the user wants to use the mobile phone 103 to establish bluetooth communication with the bluetooth dual-connection earphone 101, to perform a call, play music, or watch video, and then establishes bluetooth communication with the mobile phone 103 after waiting for the bluetooth dual-connection earphone 101 to successfully reconnect with the tablet 103 or unsuccessfully reconnect with the tablet 103 within a fixed time, so as to realize the transmission of the call, play music, or watch video, and the reconnection time of the mobile phone 103 and the bluetooth dual-connection earphone 101 is longer, thereby seriously reducing the reconnection efficiency, further affecting the transmission of the service, and the user experience is poorer.

In addition, the application also carries out a large amount of statistics on the use habits of the user, and finds that the device disconnected at last is not necessarily the device used by the user at first, and the existing reconnection method does not consider which device and the Bluetooth dual-connection earphone used by the user at first to transmit the service, so that the reconnection time of the device for transmitting the service and the Bluetooth dual-connection earphone is longer, and further the transmission of the service is influenced.

In view of this, an embodiment of the present application provides a method for controlling backhaul of a bluetooth headset, which may determine a backhaul sequence of a historical connection device according to a service data transmission condition between the bluetooth headset and the historical connection device, shorten a backhaul duration between a device for transmitting a service and the bluetooth headset, improve backhaul efficiency, and improve user experience.

In order to better understand the embodiments of the present application, the structure of the bluetooth headset according to the embodiments of the present application is described below. Fig. 4 is a schematic structural diagram of a bluetooth headset according to an embodiment of the present disclosure.

Illustratively, a bluetooth headset may include at least one processor 201, at least one memory 205, a bluetooth module 202, an audio module 203, a power module 204, an input/output interface 206, sensors, and the like. The processor 201 may include one or more interfaces for connecting with other components of the bluetooth headset.

The memory 205 may be used for storing program code, such as application program code for pairing and connecting between a bluetooth headset and an electronic device, processing audio services (e.g., music playing, making/receiving calls) of the electronic device, and the like. The memory 205 may also be used to store other information such as identity information, time of connection, time of disconnection, reason for disconnection, etc.

The processor 201 may be configured to execute the application program codes and call the relevant modules to implement the functions of the bluetooth headset in the embodiment of the present application. For example, the functions of pairing, connecting, audio playing, call receiving/making and the like between the bluetooth headset and the electronic equipment are realized.

The processor 201 may include one or more processing units, and the different processing units may be separate devices or may be integrated in one or more of the processors 201. The processor 201 may be specifically an integrated control chip, or may be composed of a circuit including various active and/or passive components, and the circuit is configured to perform the functions described in the embodiments of the present application, which belong to the processor 201.

In some embodiments, the bluetooth module 202 may be specifically a bluetooth chip. The Bluetooth headset can be matched and connected with a Bluetooth chip of the electronic equipment through the Bluetooth chip, so that wireless communication and service processing between the Bluetooth headset and the electronic equipment are realized through Bluetooth connection. In general, a bluetooth chip may support Basic Rate (BR)/Enhanced Data Rate (EDR) bluetooth and Bluetooth Low Energy (BLE), for example, may receive/transmit paging (page) information, receive/transmit BLE broadcast, and the like. The bluetooth module 202 may receive a signal to be transmitted from the processor 201, perform frequency modulation, amplify the signal, and radiate the amplified signal as electromagnetic wave via the bluetooth antenna.

The audio module 203 can be used for managing audio data and realizing the input and output of audio signals by the bluetooth headset. For example, the audio module 203 may obtain an audio signal from the bluetooth module 202, and implement functions of making and receiving calls through the bluetooth headset, playing music, activating/deactivating a voice assistant of an electronic device connected to the bluetooth headset, receiving/transmitting voice data of a user, and the like. The audio module 203 may include a speaker (or called an earphone or a receiver) component for outputting an audio signal, a microphone (or called an earphone or a receiver), a microphone receiving circuit matched with the microphone, and the like. The speaker may be used to convert the electrical audio signal into an acoustic signal and play it. The microphone may be used to convert sound signals into electrical audio signals.

The power module 204 may be configured to provide a system power for the bluetooth headset, supply power to each module of the bluetooth headset, and support the bluetooth headset to receive charging input. The power module 204 may include a Power Management Unit (PMU) and a battery. The power management unit can receive external charging input, transform the electric signal input by the charging circuit and provide the transformed electric signal to the battery for charging, and also transform the electric signal provided by the battery and provide the transformed electric signal to other modules such as the audio module 203, the bluetooth module 202 and the like, so as to prevent the battery from being overcharged, overdischarged, short-circuited or overcurrent and the like. In some embodiments, the power module 204 may also include a wireless charging coil for wirelessly charging the bluetooth headset. In addition, the power management unit can also be used for monitoring parameters such as battery capacity, battery cycle number, battery health state (leakage, impedance) and the like.

A plurality of input/output interfaces 206 may be used to provide wired connections for charging or communication with the bluetooth headset. For example, the input/output interface 206 may be a USB interface, a charging interface, or the like.

Additionally, the bluetooth headset may also include a sensor 207. For example, the sensors 207 may include a distance sensor 2073, an ambient light sensor 2072, and a temperature sensor 2071, which may be used to determine whether the bluetooth headset is being used by a user. For example, the bluetooth headset may detect whether there is an object near the bluetooth headset using the distance sensor 2073, and the ambient light sensor 2072 is used to sense the ambient light brightness; the temperature sensor 2071 is used to collect temperature. When recognizing that an object exists near the bluetooth headset, the ambient light brightness is lower than the preset brightness threshold, and the temperature is within the preset interval range (i.e., the body temperature interval of the human body), the processor 201 determines that the bluetooth headset is worn by the user.

As another example, the sensors may also include a bone conduction sensor 2074, combined into a bone conduction headset. By using the bone conduction sensor 2074, the bluetooth headset can acquire the vibration signal of the human body vocal part vibration bone block, analyze out the voice signal, realize the voice function, and thus receive the voice command of the user. The Bluetooth headset can also perform voice authentication according to the user voice signal acquired by the bone conduction headset so as to authenticate the user identity in service scenes such as payment transaction and the like.

It is to be understood that the illustrated structure of the embodiments of the present application does not constitute a specific limitation to the bluetooth headset. It may have more or fewer components, may combine two or more components, or may have a different configuration of components. For example, the external surface of the bluetooth headset may further include a key, an indicator light (which may indicate the status of power, incoming/outgoing call, pairing mode, etc.), a display screen (which may prompt the user for relevant information), a dust screen (which may be used with an earphone), and the like. The key may be a physical key or a touch key (used in cooperation with the touch sensor), and is used for triggering operations such as startup, shutdown, pause, play, recording, pairing start, and reset. The method of device loopback in a possible design will be described below by taking a bluetooth headset as a bluetooth dual-connection headset as an example.

In the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same or similar items having substantially the same function and action. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

It is noted that, in the present application, words such as "exemplary" or "for example" are used to mean exemplary, illustrative, or descriptive. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

According to the control method for the Bluetooth headset reconnection, when the Bluetooth headset is in the headset box and the headset box is in an open state, the Bluetooth headset can determine the reconnection sequence of M historical connection devices according to the service data transmission condition of the Bluetooth headset and each historical connection device in the M historical connection devices, wherein M is an integer greater than 1; and according to the reconnection sequence, performing reconnection on the M historical connection devices.

If M equals 2, the Bluetooth headset is a dual-connection headset, when the Bluetooth headset is in the headset box and the headset box is in an open state, the Bluetooth headset can determine the reconnection sequence of the 2 historical connection devices according to the service data transmission condition of the Bluetooth headset and each historical connection device in the 2 historical connection devices, namely, the device with the preferential reconnection and the device with the subsequent reconnection are determined.

If M is greater than or equal to 3, when the bluetooth headset is in the headset box and the headset box is in an open state, the bluetooth headset may determine the connection sequence of the M historical connection devices according to the service data transmission condition between the bluetooth headset and each historical connection device in the M historical connection devices, that is, determine a first connection device (a device that is connected back preferentially), a second connection device (a device that is connected back next time), … …, and an mth connection device (a device that is connected back last).

For convenience of description, the bluetooth headset is taken as a bluetooth dual-connection headset for illustration.

Fig. 5 shows a schematic flowchart of a control method 500 for bluetooth headset loopback according to an embodiment of the present application. The method 500 may be applied to the scenario shown in fig. 2, but the embodiment of the present application is not limited thereto. The method 500 may be performed by a bluetooth headset, such as the bluetooth dual connectivity headset 101 shown in fig. 2, but the embodiment of the present application is not limited thereto. The structure of the bluetooth headset may be as shown in fig. 4, but the embodiment of the present application is not limited thereto.

For convenience of description, the embodiment of the present application takes a bluetooth headset as a bluetooth dual-connection headset as an example for explanation. Devices connected to a bluetooth dual-connection headset may be referred to as a first device and a second device. The first device may also be referred to as a first historical connection device, and the second device may also be referred to as a second historical connection device, which is not limited in this embodiment of the present application.

As shown in fig. 5, the method 500 may include the steps of:

s501, when the Bluetooth double-connection earphone is in the earphone box and the earphone box is in an open state, the time when the first device transmits the service for the last time and the time when the second device transmits the service for the last time are obtained.

The first device and the second device may be the mobile phone 102 and the tablet 103, or may be the mobile phone a and the mobile phone B, which is not limited in this embodiment of the present application.

The Bluetooth dual connection earphone is arranged in the earphone box, the earphone box is in an open state, and meanwhile, when the distance between the Bluetooth dual connection earphone and the first device and the distance between the Bluetooth dual connection earphone and the second device are smaller than the maximum distance supported by the Bluetooth technology, the Bluetooth dual connection earphone is in a back connection state.

There are many possible implementations for the bluetooth dual-connection headset to acquire the time when the first device last transmits a service and the time when the second device last transmits a service.

In a possible implementation manner, under the condition that the bluetooth dual-connection headset performs bluetooth service transmission with the first device and the second device respectively, the bluetooth dual-connection headset may record the time when the first device transmits a service each time and the time when the second device transmits a service each time. When the Bluetooth dual connection earphone is disconnected with the first equipment, the disconnection time of the first equipment is recorded, and when the Bluetooth dual connection earphone is disconnected with the second equipment, the disconnection time of the second equipment is recorded. The bluetooth dual-connection earphone may determine a time, which is the closest to a disconnection time of the first device, among times of transmitting the service of each time by the first device, as a time of transmitting the service of the first device for the last time, and may determine a time, which is the closest to a disconnection time of the second device, among times of transmitting the service of each time by the second device, as a time of transmitting the service of the second device for the last time. The reason why the bluetooth dual-connection earphone is disconnected from the first device and the second device respectively may be that the distance between the bluetooth dual-connection earphone and the two devices exceeds the maximum distance supported by the bluetooth technology, or that the bluetooth dual-connection earphone is in an earphone box, and the earphone box is in a closed state, which is not limited in the embodiment of the present application.

The states of the bluetooth dual-connection earphone can comprise an idle state, a call state, a music state, a video state and the like. When the Bluetooth dual connection earphone detects that the Bluetooth dual connection earphone is in a conversation state, a music state, a video state and other states, the Bluetooth dual connection earphone can be determined to perform Bluetooth service transmission with connected equipment.

The time of transmitting the service may be the time of starting the service transmission, the time of ending the service transmission, or any time in the process of transmitting the service, which is not limited in the embodiment of the present application.

The time of each service transmission may be the time of each service transmission starting, the time of each service transmission ending, or any time in each service transmission process, which is not limited in the embodiments of the present application.

In the process of establishing the bluetooth communication between the bluetooth dual connection earphone and the first device, the bluetooth dual connection earphone can record the time of each service transmission of the first device, and can also store the time of each service transmission into the database. In the process of establishing the bluetooth communication between the bluetooth dual connection earphone and the second device, the bluetooth dual connection earphone can record the time of each service transmission of the second device, and can also store the time of each service transmission into the database.

The bluetooth dual-connection earphone can store the time of transmitting the service of the first device and the time of transmitting the service of the second device each time respectively, and also can store the time into the same database, and the embodiment of the application does not limit the time.

It should be noted that, if the bluetooth dual-connection headset stores the time when the first device transmits the service each time and the time when the second device transmits the service each time in the same database, the bluetooth dual-connection headset may add an identifier to data of different devices, where the identifier may include at least one of a device identifier, a digital identifier, and a symbol identifier, for example.

According to the implementation mode, the Bluetooth dual-connection earphone records the time of transmitting the service every time, and the use of the user is recorded in detail, so that the use habit of the user can be known conveniently, and the scheme can be optimized according to the use habit of the user subsequently.

In another possible implementation manner, when the bluetooth dual-connection headset performs bluetooth service transmission with the first device and the second device, the bluetooth dual-connection headset may record the time when the first device and the second device transmit services, respectively, and update the time in real time, that is, only one time is recorded for one device, and the time is updated in real time according to the transmission of the services. When the bluetooth dual-connection earphone is disconnected from the first device and the second device, the bluetooth dual-connection earphone may determine the recorded time when the first device transmits the service as the time when the first device transmits the service last time, and determine the recorded time when the second device transmits the service as the time when the second device transmits the service last time.

In the process of establishing the bluetooth communication between the bluetooth dual-connection earphone and the first device, the bluetooth dual-connection earphone can record the time when the first device transmits the service for the first time, and when the bluetooth dual-connection earphone detects that the first device transmits the service for the second time, the time when the first device transmits the service for the first time is updated to the time when the first device transmits the service for the second time, and so on until the bluetooth dual-connection earphone is disconnected from the first device. Similarly, in the process of establishing the bluetooth communication between the bluetooth dual connection earphone and the second device, the bluetooth dual connection earphone can record the time when the second device transmits the service for the first time, and when the bluetooth dual connection earphone detects that the second device transmits the service for the second time, the time when the service is transmitted for the first time is updated to the time when the service is transmitted for the second time, and so on until the bluetooth dual connection earphone is disconnected with the second device.

By the implementation mode, the Bluetooth dual-connection earphone only records one moment for one device, so that the storage space can be saved.

In yet another possible implementation manner, the bluetooth dual-connection headset may record the time when the first device transmits the service each time, and record the time when the second device transmits the service, and update the time in real time. When the bluetooth dual-connection earphone is disconnected with the first device and the second device, the bluetooth dual-connection earphone may determine a time, which is the closest to the time when the first device is disconnected, from the times when the first device transmits the service each time, as a time when the first device transmits the service last time, and determine the recorded time when the second device transmits the service as a time when the second device transmits the service last time.

Or, the bluetooth dual-connection earphone may record the time when the first device transmits the service, update the time in real time, and record the time when the second device transmits the service each time. When the bluetooth dual-connection earphone is disconnected with the first device and the second device, the bluetooth dual-connection earphone may determine the recorded time when the first device transmits the service as the time when the first device transmits the service for the last time, and determine the time, which is the closest to the time when the second device is disconnected, from the time when the second device transmits the service for each time as the time when the second device transmits the service for the last time.

The realization mode can record the time of transmitting the service in different modes aiming at different devices, is flexible and changeable, and can be suitable for more scenes.

S502, the Bluetooth double-connection earphone determines the equipment which transmits the service last time according to the time when the first equipment transmits the service last time and the time when the second equipment transmits the service last time.

If the time of the last service transmission of the first device is later than the time of the last service transmission of the second device, the Bluetooth dual-connection earphone can determine the first device as the device of the last service transmission; if the time of the last service transmission of the second device is later than the time of the last service transmission of the first device, the bluetooth dual-connection headset may determine the second device as the device of the last service transmission.

And S503, the Bluetooth double-connection earphone sends a connection signal back to the equipment which finally transmits the service.

The bluetooth dual connectivity headset may preferentially send back a connectivity signal to the device that last transmitted the traffic.

If the last device for transmitting the service is the first device and the bluetooth dual-connection headset is successfully connected back to the first device, the bluetooth dual-connection headset can send a connection signal back to the second device. If the last device for transmitting the service is the first device and the Bluetooth dual connection earphone is unsuccessfully connected back to the first device, the Bluetooth dual connection earphone can continuously send the connection signal back to the first device until the fixed time length is reached.

It should be noted that, in the embodiment of the present application, it is considered that the device which transmits the service last may be a device which transmits the service first after the bluetooth dual-connection headset is successfully connected back, so that the device which preferentially connects back the service last can shorten the time length for connecting back the device which transmits the service and the bluetooth headset.

It should be noted that, if the bluetooth headset may be connected to 3 or more than 3 devices simultaneously, the bluetooth headset may sort the 3 or more than 3 historical connection devices from back to front according to the last time of transmitting services with the bluetooth headset, and the later the last time of transmitting services, the earlier the connection sequence of the devices.

According to the control method for the Bluetooth headset reconnection, when the Bluetooth double-connection headset is connected with the first device and the second device in a reconnection mode, the last device for transmitting the service can be preferentially connected in the reconnection mode, the time for the device for transmitting the service to be connected in the reconnection mode with the Bluetooth headset is shortened, the reconnection efficiency is improved, and the user experience is improved.

In the method 500, the device that transmits the service last time is the device that transmits the service last time after the last connection with the bluetooth dual-connection earphone is successful, and the bluetooth dual-connection earphone may further determine the device that transmits the service last time as the device that transmits the service preferentially according to the time of transmitting the service after the connection with the bluetooth dual-connection earphone is successful for multiple times, and perform the reconnection.

Illustratively, each time the bluetooth dual-connection headset is disconnected from the first device and the second device, the device that last transmits a service is recorded, and the device that last transmits a service is recorded N times, if the first device has S1 times and is the last device that performs service data transmission with the bluetooth headset, the second device has S2 times and performs transmission service for the last device that performs service data transmission with the bluetooth headset, and S1 is greater than S2, the first device is the device that preferentially transmits a service, and the bluetooth dual-connection headset can preferentially perform a backhaul connection thereto.

The control method for Bluetooth headset reconnection provided by the embodiment of the application can preferentially reconnect the equipment which carries out service data transmission for the last time with the Bluetooth dual-connection headset, can more accurately grasp the use habit of a user, and is favorable for accurately judging the equipment which preferentially transmits services.

In order to accurately predict the device for transmitting the service for the first time after the bluetooth dual-connection earphone successfully reconnects, the embodiment of the application provides that the bluetooth dual-connection earphone can count the device for transmitting the service for the first time after the bluetooth dual-connection earphone successfully reconnects, and the device with the largest number of times of service transmission for the first time is determined as the device for preferentially reconnecting the bluetooth dual-connection earphone.

Illustratively, fig. 6 shows a schematic flowchart of a method 600 for controlling bluetooth headset backhaul provided in an embodiment of the present application. The method 600 may be applied to the scenario shown in fig. 2, but the embodiment of the present application is not limited thereto. The method 600 may be performed by a bluetooth headset, such as the bluetooth dual connectivity headset 101 shown in fig. 2, but the embodiment of the present application is not limited thereto. The structure of the bluetooth dual-connection headset may be as described in fig. 4, but the embodiment of the present application is not limited thereto.

As shown in fig. 6, the method 600 may include the steps of:

s601, when the Bluetooth double-connection earphone is in the earphone box and the earphone box is in an open state, acquiring the history return connection equipment preferentially used.

Before the historical reconnection is performed, namely before the reconnection, after the Bluetooth double-connection earphone is successfully connected back, the equipment for transmitting the service for the first time or the equipment for transmitting the service for the first time is the most frequently.

In a possible implementation manner, the device preferentially used by the historical backhaul is a device that transmits the service for the first time after the last backhaul connection is successful.

Before the next reconnection, when the bluetooth dual-connection earphone is in the reconnection state, the bluetooth dual-connection earphone may preferentially reconnect the device that is last disconnected, and may also preferentially reconnect the device that is last to transmit a service. And recording the equipment for transmitting the service for the first time after the Bluetooth double-connection earphone is successfully connected back. In this state of reconnection, the bluetooth dual-connection headset may use the device that first transmits a service as the device that preferentially reconnects.

In the implementation mode, each reconnection can take the equipment which transmits the service for the first time after the last success as the equipment with priority reconnection, can be changed according to the use habit of the user, is flexible and changeable, and better accords with the use habit of the user.

In another possible implementation manner, the device preferentially used by the historical reconnection is the device which transmits the service for the first time after the reconnection succeeds for the most time.

Before the next reconnection, when the bluetooth dual-connection earphone is in the reconnection state, the bluetooth dual-connection earphone may preferentially reconnect the device that was last disconnected, may also preferentially reconnect the device that last transmitted the service, and may also preferentially reconnect the device that last transmitted the service for the first time. And recording the equipment for transmitting the service for the first time after the Bluetooth double-connection earphone is successfully connected back. Each time the Bluetooth double-connection earphone is successfully connected back, the equipment for firstly transmitting the service can be recorded. In this reconnection state, the bluetooth dual-connection headset may count the recorded devices, and determine the device with the largest number of times of first service transmission as the device with the priority of reconnection.

Illustratively, each time the bluetooth dual-connection headset is disconnected from the first device and the second device, the device recording the first transmission service records N times of the device recording the first transmission service, if the first device has S1 times and is the first device performing service data transmission with the bluetooth headset, the second device has S2 times and is the first device performing service data transmission with the bluetooth headset, and S1 is greater than S2, the first device is the device preferentially transmitting the service, and the bluetooth dual-connection headset can preferentially perform loop connection with the first device and the second device.

In the implementation mode, the device with the largest number of devices for transmitting the service for the first time is used as the device with the priority for the reconnection, so that the use habit of the user can be estimated, the device for transmitting the service by the user is pre-judged, and the device with the priority for the reconnection is performed.

And S602, the Bluetooth dual-connection earphone sends a connection signal back to the equipment preferentially used by the historical connection back.

The bluetooth dual-connected headset may preferentially send back a connect signal to the device that is preferentially used by the historical reconnect.

If the history reconnection priority used device is the first device and the Bluetooth dual-connection earphone is successfully reconnected with the first device, the Bluetooth dual-connection earphone can send a connection signal back to the second device. If the device preferentially used by the historical reconnection is the first device and the Bluetooth dual-connection earphone is unsuccessfully reconnected with the first device, the Bluetooth dual-connection earphone can continuously send a connection signal back to the first device until the fixed time length is reached.

It should be noted that, in the embodiment of the present application, it is considered that the device preferentially used for historical backhaul may be a device that transmits a service for the first time after the bluetooth dual-connection headset successfully backhaul, and therefore preferentially reconnects the device preferentially used for historical backhaul, which can shorten the backhaul duration between the device that transmits the service and the bluetooth headset.

It should be further noted that, if the bluetooth headset may be connected to 3 or more than 3 devices at the same time, the bluetooth headset may sort the 3 or more than 3 historical connection devices from front to back according to the time of the first service transmission with the bluetooth headset after the connection with the bluetooth headset is successful, and the earlier the time of the first service transmission with the bluetooth headset is, the earlier the connection back sequence is.

According to the control method for the Bluetooth headset reconnection, when the Bluetooth dual-connection headset is connected with the first device and the second device in a reconnection mode, the devices which are used preferentially in the historical reconnection mode can be connected in a reconnection mode preferentially, the time for the service transmission device and the Bluetooth headset to be connected in the reconnection mode is shortened, the reconnection efficiency is improved, and the user experience is improved.

The above-mentioned control method for bluetooth headset reconnection determines the device that transmits the service last and the device that is preferentially used by the historical reconnection as the device that transmits the service.

Fig. 7 is a schematic flowchart of a method 700 for controlling bluetooth headset backhaul provided in an embodiment of the present application. The method 700 may be applied to the scenario shown in fig. 2, but the embodiment of the present application is not limited thereto. The method 700 may be performed by a bluetooth headset, such as the bluetooth dual connectivity headset 101 shown in fig. 2, but the embodiment of the present application is not limited thereto. The structure of the bluetooth dual-connection headset may be as described in fig. 4, but the embodiment of the present application is not limited thereto.

As shown in fig. 7, the method 700 may include the steps of:

s701, when the Bluetooth dual connection earphone is in a loop connection state, the Bluetooth dual connection earphone counts the times of service transmission of the first device and the times of service transmission of the second device.

The bluetooth dual-connection earphone may count the number of times that the first device transmits the service and the number of times that the second device transmits the service after the last reconnection is successful, and may also count the number of times that the first device transmits the service and the number of times that the second device transmits the service after the multiple reconnection is successful, which is not limited in the embodiment of the present application.

If the Bluetooth dual connection earphone counts the times of service transmission of the first equipment and the times of service transmission of the second equipment after the last successful reconnection, the Bluetooth dual connection earphone can update the equipment which is preferentially reconnected after each successful reconnection in real time, and the flexibility is stronger.

If the Bluetooth dual-connection earphone counts the times of service transmission of the first device and the times of service transmission of the second device after multiple times of successful reconnection, the using habits of the user can be more accurately counted, and the devices for service transmission after successful reconnection can be more accurately pre-judged.

S702, determining equipment with more service transmission times by the Bluetooth double-connection earphone according to the service transmission times of the first equipment and the service transmission times of the second equipment.

If the number of times of service transmission of the first device is greater than that of the second device, the bluetooth dual-connection headset may determine that the first device is a device with more service transmission times. If the number of times of service transmission of the second device is greater than that of the first device, the bluetooth dual-connection earphone may determine the second device as a device with more service transmission times.

If the number of times of service transmission by the first device is equal to the number of times of service transmission by the second device, the bluetooth dual-connection headset may perform the method 500 or the method 600, which is not limited in this embodiment.

And S703, the Bluetooth double-connection earphone sends back a connection signal to the equipment with more service transmission times.

The bluetooth dual connection headset can preferentially send back the connection signal to the device which has more transmission service times.

If the device with more service transmission times is the first device and the Bluetooth dual connection earphone is successfully connected back with the first device, the Bluetooth dual connection earphone can send a connection signal back to the second device. If the device with more service transmission times is the first device and the Bluetooth dual-connection earphone is unsuccessfully reconnected with the first device, the Bluetooth dual-connection earphone can continuously send a connection signal back to the first device until a fixed time length is reached.

It should be noted that, in the embodiment of the present application, it is considered that the device with the large number of times of service transmission may be a device which transmits the service for the first time after the bluetooth dual-connection headset completes the loopback operation, so that the device with the large number of times of service transmission is preferentially looped back, and the looping time of the device which transmits the service and the bluetooth headset can be shortened.

It should be further noted that, if the bluetooth headset may be connected to 3 or more than 3 devices at the same time, the bluetooth headset may also sort the 3 or more than 3 historical connection devices from the number of times of transmitting services with the bluetooth headset after the connection with the bluetooth headset is successful, and the device with the greater number of times of transmitting services with the bluetooth headset may have the earlier connection back sequence.

According to the control method for the Bluetooth headset reconnection, when the Bluetooth dual-connection headset is connected with the first device and the second device, the number of times of service transmission can be preferentially connected, the time for the service transmission device and the Bluetooth headset to be connected back is shortened, the connection back efficiency is improved, and the user experience is improved.

Optionally, different priorities may be set for different services in the embodiment of the present application, and the bluetooth dual-connection headset may send a connection signal back to a device that transmits a service with a high priority. The priority of the service may be preset or set by a user, which is not limited in the embodiment of the present application. The number of services corresponding to the same priority may be one or multiple, and this is not limited in this embodiment of the application.

Illustratively, the navigation service and the call service may be higher priority level than the video service and the music service, and the bluetooth dual-connection headset may preferentially transmit a connection signal back to the device transmitting the navigation service and/or the call service.

The method 500, the method 600, or the method 700 may be performed by the bluetooth dual connectivity headset when the first device and the second device both transmit traffic with a high priority level, which is not limited in this embodiment of the present application.

Optionally, the method and the device for processing the bluetooth dual-connection service may further include counting the duration of the service transmission between the first device and the bluetooth dual-connection earphone last time and the second device, and when the bluetooth dual-connection earphone is in the earphone box and the earphone box is in an open state, acquiring the duration of the service transmission last time of the first device and the duration of the service transmission last time of the second device; determining the equipment with the longest service duration according to the last service transmission duration of the first equipment and the last service transmission duration of the second equipment; and preferentially connecting the equipment with the longest service duration back.

If the last service transmission time length of the first equipment is longer than the last service transmission time length of the second equipment, the first equipment is preferentially reconnected, namely the reconnection sequence is the first equipment and the second equipment; if the last service transmission time length of the second device is longer than the last service transmission time length of the first device, the second device is preferentially reconnected, namely the reconnection sequence is the second device and the first device.

Optionally, in this embodiment of the present application, the duration of service transmission between the first device and the second device (which may be N times) and the bluetooth dual-connection headset may be counted, and the device with the largest number of times of service transmission duration may be determined as the device that is preferentially connected back.

Illustratively, when the bluetooth dual-connection earphone is disconnected from the first device and the second device each time, the duration of service transmission is recorded, the device with the longest service transmission duration is determined according to the duration of service transmission, and the device with the longest service transmission duration is continuously recorded for N times. If the first device has the device with the longest transmission service duration for S1 times, the second device has the device with the longest transmission service duration for S2 times, and S1 is greater than S2, the first device is a device with a priority for loop connection, and the bluetooth dual-connection headset can preferentially loop the device.

It should be noted that, if the connection back sequence cannot be determined according to the service duration, the bluetooth dual-connection headset may perform the method 500, the method 600, or the method 700, which is not limited in this embodiment.

The sequence numbers of the above processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not be limited in any way to the implementation process of the embodiments of the present application.
