The motor 291 may be used for incoming call vibration alerting or for touch vibration feedback. The indicator 292 may be an indicator light, which may be used to indicate a state of charge, a change in power, a message indicating a missed call, a notification, etc. The SIM card interface 295 is for interfacing with a SIM card. The SIM card may be inserted into the SIM card interface 295 or removed from the SIM card interface 295 to allow contact and separation from the handset 200. The handset 200 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 295 may support Nano SIM cards, micro SIM cards, and the like.

The software system of the mobile phone 200 may employ a layered architecture, an event driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. In the embodiment of the application, taking an Android system with a layered architecture as an example, a software structure of the mobile phone 200 is illustrated.

Fig. 4 illustrates a block diagram of the software architecture of a mobile phone 200, according to some embodiments of the application. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun rows (Android run times) and system libraries, and a kernel layer.

As shown in fig. 4, the application layer may include applications for music, video, conversation, ringing, alarm, bluetooth, navigation, audio manager, gallery, recording, etc. Of course, the application layer may also include other application programs, such as a payment application, a shopping application, a banking application, a chat application, or a financial application, and the application is not limited thereto. The audio manager is used for sensing the state of the Bluetooth headset for processing audio service: idle, processing audio traffic. The audio manager is also configured to sense preemption events for the audio traffic and state restoration events for the audio traffic. The preemption of the audio service refers to a process that when the Bluetooth headset processes the audio service, another electronic device initiates the audio service to be processed, and then, the audio service being processed is suspended to process the audio service to be processed initiated by the other electronic device. The state recovery event of the audio service refers to a process that after the preemption event of the audio service occurs, the Bluetooth headset pauses processing the audio service to be processed initiated by another electronic device, and pauses processing the audio service before processing. The audio manager is further configured to display first prompt information, where the first prompt information is used to instruct a user to perform selection of audio service preemption processing and status recovery processing of the audio service. For example, an audio manager is used to display the aforementioned "one key reseize" pop-up window.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions. For example, a telephony manager, a computing engine, a notification manager, a multimedia framework, a state aware module, a process manager, etc., to which embodiments of the present application are not limited in any way.

Wherein the process manager is used to create, suspend processes and threads.

The telephony manager is used to provide the communication functions of the handset 200. Such as the management of call status (including on, hung-up, etc.).

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

The state sensing module is mainly responsible for confirming the state of the mobile phone 200 itself and the state of a wireless device (e.g. bluetooth headset 100) connected with bluetooth of the mobile phone 200. The state of the mobile phone 200 itself may include an active state and a non-active state, and the state of the device connected to the bluetooth of the mobile phone may include an idle state or a non-idle state. The state sensing module can confirm the state of the mobile phone 200 itself by monitoring various application processes and threads. The state sensing module may determine the state of the device connected to bluetooth of the handset 200 through the received broadcast information (e.g., BLE broadcast).

The multimedia framework can receive audio services sent by each application program of the application layer and identify the type of the audio services; and carrying out service arbitration and preemption. In the embodiment of the application, the multimedia framework is used for determining the type of the audio service according to the type of the audio stream in the audio service request under the condition of receiving the audio service processing request sent by the application program, and then selecting the audio playing device according to the state of processing the audio service by the Bluetooth earphone. The multimedia framework is also used for sending the audio service preemption notification to the Bluetooth module under the condition of receiving the audio service preemption notification sent by the audio manager.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), two-dimensional graphics processing Libraries (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio video encoding formats, such as: MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

OpenGL ES is used to implement three-dimensional graphics drawing, image rendering, compositing, and layer processing, among others.

SGL is the drawing engine for 2D drawing.

Android Runtime (Android run) includes a core library and virtual machines. Android run is responsible for scheduling and management of the Android system. The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android. The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver, a sensor driver and a Bluetooth module.

In addition, a hardware layer is further included between the system library and the kernel layer, and the hardware layer includes a display, a camera, a speaker (also referred to as a speaker), a bluetooth module, and the like. The Bluetooth module can comprise a hardware unit for realizing Bluetooth connection and data interaction: a Radio frequency unit (Radio), a baseband or link control unit (link controller), a link management unit (LINK MANAGER), and the like. The wireless Radio frequency unit is used for realizing the wireless Radio frequency unit (Radio) for transmitting/receiving data and voice; the link management unit is used for carrying out the mutual conversion between the radio frequency signal and the digital or voice signal and realizing the baseband protocol and other bottom layer connection regulations; the link management unit is responsible for managing communication between Bluetooth devices and realizing operations such as link establishment, verification, link configuration and the like.

The following embodiments are presented in conjunction with the accompanying drawings to describe application scenarios and methods of embodiments of the present application.

In the embodiment of the present application, the method of the embodiment of the present application is described by taking the example that the electronic device 1 (i.e. the first electronic device) is the mobile phone 200, the electronic device 2 (i.e. the second electronic device) is the tablet pc 300, and the bluetooth headset is the bluetooth headset 100. Wherein audio service 1 is a first audio service and audio service 2 is a second audio service.

In the embodiment of the present application, as shown in fig. 1, both the mobile phone 200 and the tablet pc 300 may establish a wireless communication channel (e.g., a physical connection) with the bluetooth headset 100. The mobile phone 200 can process the audio service 1 using the bluetooth headset 100, such as playing music of the mobile phone 200 using the bluetooth headset 100. Thereafter, as shown in fig. 2, the tablet 300 may detect the audio service 2. For example, tablet 300 may receive an incoming call, requiring a phone call to be answered using bluetooth headset 100; or tablet 300 may need to play music using bluetooth headset 100. At this time, the service priority of the audio service 2 may be greater than or equal to the service priority of the audio service 1. For example, in the case where the audio service 2 is to answer an incoming call and the audio service 1 is to play music, the service priority of the audio service 2 is higher than that of the audio service 1. For another example, in the case where the audio service 2 is playing music and the audio service 1 is playing music, the service priority of the audio service 2 is equal to the service priority of the audio service 1. The embodiment of the present application will be described hereinafter with reference to the priority of each audio service, which is not described here again.

In the case where the service priority of the audio service 2 is greater than or equal to the service priority of the audio service 1, the tablet 300 may request the bluetooth headset 100 to suspend processing the audio service 1 (e.g., playing music of the mobile phone 200) and process the audio service 2 (e.g., answering an incoming call of the tablet 300) using the bluetooth headset 100. At this time, the audio service 1 of the cellular phone 200 is preempted by the audio service 2 of the tablet 300.

In order to ensure that the audio service 1 of the mobile phone 200 is preempted by the audio service 2 of the tablet pc 300, the audio service 1 of the mobile phone 200 may preempt the usage rights of the bluetooth headset 100. The handset 200 may provide the user with a "one-key reseize" service. Specifically, after the bluetooth headset 100 pauses processing the audio service 1, the mobile phone 200 may display the first prompt information. The first prompt message is used to request the user to determine whether the mobile phone 200 resumes processing the audio service 1 with the bluetooth headset 100. That is, the first hint information is used to request the user to determine whether the audio service 1 is to re-preempt the right of use of the bluetooth headset 100. For example, fig. 5 shows an application scenario of an audio service restoration processing method according to some embodiments of the present application, as shown in fig. 5, after the bluetooth headset 100 pauses playing music of the mobile phone 200 and plays music of the tablet 300, the mobile phone 200 displays a "one-key reseize" pop-up window. Fig. 6 illustrates a schematic diagram of an operator interface of a "one-key reseize" window, as shown in fig. 6, and the handset 200 displays a "one-key reseize" pop-up window 1, according to some embodiments of the application. "one key reseize" popup window 1 includes prompt information: "does it resume processing audio service 1 with bluetooth headset 100? ", and a confirm option and a cancel option. The mobile phone 200 detects that the user clicks the confirmation option in the pop-up window 1 of "one key reseize", the audio service 1 of the mobile phone 200 can re-preempt the right to use of the bluetooth headset 100. Fig. 7 is a schematic view of an application scenario of an audio service restoration processing method according to some embodiments of the present application, as shown in fig. 7, after the mobile phone 200 detects that the user clicks the confirm option in the pop window of "one key reseize", the mobile phone 200 may request the bluetooth headset 100 to pause playing of music of the tablet 300, and play music of the mobile phone 200 by using the bluetooth headset 100, so that the bluetooth headset 100 resumes playing music of the mobile phone 200 again. The first prompt information may be displayed on the desktop of the mobile phone 200, or may be displayed on an interface of an audio application, or may be displayed in a pull-down notification management menu of the mobile phone 200.

In the scheme, the audio service of one electronic device with higher service priority is determined to be processed instead of simply according to the service priority sequence set by the audio service. After suspending playing of the music of the handset 200, it may be decided by the user whether to continue the audio service. Then, whether to resume the preempted music playing of the mobile phone 200 can be selected according to the user's wish. Therefore, the flexibility of audio service switching is improved, and the user experience is improved.

In the embodiment of the application, different audio services can correspond to different priorities. Higher priority audio services are often important, critical audio services, which may be prioritized by the bluetooth headset. By way of example, the audio services may include a plurality of types, for example, the audio services may include a call service, a multimedia service, a notification prompt service, and the like. The call service may include playing the voice data of the opposite terminal for the user in the scenes of a phone call (including a phone call in and a phone call out), a video call, an audio call, a voice message, a game or a voice assistant, or collecting the voice data of the user and sending to the opposite terminal, playing an incoming call bell, etc. Multimedia services may include playing music, video, sound recordings, background music for games, text-to-speech sounds, etc. The notification alert service may include play a short message alert tone, push notification alert tone, alarm bell, system sound (e.g., sound when volume is adjusted, shutter sound when shooting, etc.). The priority of the notification prompt service, the multimedia service and the call service are sequentially increased. In other embodiments, the audio service may include more types, and is not particularly limited herein. The priority of the audio service may be preset, or may be set actively by the user, which is not limited herein. For example, the service priority of the call service is greater than the service priority of the multimedia service, which is greater than the service priority of the notification prompt service.

In some embodiments, after detecting audio service 2, tablet 300 requests bluetooth headset 100 to suspend processing audio service 1 and process audio service 2 using bluetooth headset 100. The method specifically comprises the following implementation scheme: fig. 8 is a schematic view of an application scenario of an audio service restoration processing method according to some embodiments of the present application. As shown in fig. 8, the tablet 300 detects the audio service 2, for example, the tablet 300 may receive an incoming call, which requires to answer the phone using the bluetooth headset 100; or tablet 300 may need to play music using bluetooth headset 100. The tablet pc 300 transmits a service suspension instruction to the mobile phone 200 through the bluetooth headset 100. The handset 200 may receive the service suspension instruction. After the mobile phone 200 receives the service suspension instruction, the sending of the audio data of the audio service 1 to the bluetooth headset 100, such as playing the audio data corresponding to the music of the mobile phone 200, may be stopped. Also, the tablet 300 may transmit audio data of the audio service 2 to the bluetooth headset 100. The bluetooth headset 100 receives audio data of the audio service 2, and processes the audio service 2, such as playing music of the tablet 300 using the bluetooth headset 100.

In this embodiment, the tablet 300 may request the bluetooth headset 100 to suspend processing of the audio service 1 through the service suspension instruction, and process the audio service 2 using the bluetooth headset 100 to implement preemption of the audio service 1 by the audio service 2.

It should be noted that, in this embodiment, the bluetooth headset 100 may function as a relay of data or signaling (such as the service suspension instruction described above) between the tablet 300 and the mobile phone 200. The bluetooth headset 100 may transmit data or signaling received from the tablet pc 300 to the mobile phone 200, or may transmit data or signaling received from the mobile phone 200 to the tablet pc 300.

In other embodiments, after the bluetooth headset 100 receives the data or signaling from the tablet 300 or the mobile phone 200, some corresponding operations are performed in response to the data or signaling. For example, after receiving the service suspension instruction from the tablet pc 300, the bluetooth headset 100 may not only transmit the service suspension instruction to the mobile phone 200; processing of the audio service 1 of the handset 200 may also be stopped in response to the service suspension instruction.

In some embodiments, after the tablet 300 detects the audio service 2, the bluetooth headset 100 is requested to suspend processing the audio service 1, and the bluetooth headset 100 is used to process the audio service 2, which includes the following specific implementation schemes: the mobile phone 200 indicates the service priority of the audio service 1 to the tablet pc 300 through the bluetooth headset 100; after detecting the audio service 2, the tablet 300 compares the service priorities of the audio service 2 and the audio service 1; if the service priority of the audio service 2 is greater than the service priority of the audio service 1, the tablet 300 requests the bluetooth headset 100 to suspend processing the audio service 1, and processes the audio service 2 by using the bluetooth headset 100.

In some embodiments, the service suspension instruction is used to indicate a service priority of the audio service 2; the mobile phone 200 receives the service suspension instruction and stops sending the audio data of the audio service 1 to the bluetooth headset 100, which comprises the following specific implementation schemes: the mobile phone 200 receives the service suspension instruction, and stops sending the audio data of the audio service 1 to the bluetooth headset 100 if the service priority of the audio service 2 indicated by the service suspension instruction is greater than the service priority of the audio service 1. In this scheme, after receiving the service suspension instruction, the mobile phone 200 again confirms the service priority of the audio service 2 and the audio service 1, so as to further ensure the accuracy of executing the service suspension instruction by the mobile phone 200.

It can be understood that, when the audio services requiring the right of use of the bluetooth headset 100 are at the same service priority, the tablet 300 initiating the audio service later can display the prompt information for requesting the user to determine whether the tablet 300 preempts the bluetooth headset 100 to process the audio service 2, so that the user will determine whether to process the audio service 2 initiated later earlier, thereby improving the user experience. Specifically, in some embodiments, if the service priority of the audio service 2 is equal to the service priority of the audio service 1, the tablet 300 displays the second prompt message; wherein, the second prompt message is used for requesting the user to determine whether the tablet pc 300 preempts the bluetooth headset 100 to process the audio service 2; the tablet 300 requests the bluetooth headset 100 to suspend processing the audio service 1 and processes the audio service 2 using the bluetooth headset 100 in response to a third operation of the second prompt message by the user; wherein the third operation is used to trigger the tablet 300 to preempt the bluetooth headset 100 to process the audio service 2. The second prompt information may be displayed on the desktop of the tablet pc 300, may be displayed on the interface of the audio application of the tablet pc 300, or may be displayed in a drop-down notification management menu of the tablet pc 300. The operation interface of the tablet pc 300 may include the second prompt information and the corresponding confirm option button at the same time, and the third operation may be a user selection operation of the confirm option button corresponding to the second prompt information, for example, the user clicks the confirm option button.

It can be understood that, in order to improve the efficiency of the mobile phone 200 to resume the originally suspended audio service, the display time of the first prompt information needs to be controlled to be within a certain time, and if the first operation of the first prompt information by the user is detected within the control time, the mobile phone 200 resumes the originally suspended audio service.

Specifically, in some embodiments, if the mobile phone 200 receives the first operation of the user on the first prompt message within the first preset duration, the mobile phone 200 responds to the first operation to request the bluetooth headset 100 to suspend processing the audio service 2, and uses the bluetooth headset 100 to process the audio service 1. The first preset time period may be any one of 10 seconds to 1 minute.

In other embodiments, even if the mobile phone 200 does not detect that the user timely performs the selection operation of resuming the originally suspended audio service, the mobile phone 200 can automatically resume the processing of the audio service 1 by the bluetooth headset 100 after the bluetooth headset 100 processes the audio service 2. Specifically, if the mobile phone 200 does not receive the operation of the user on the first prompt message within the first preset duration, the mobile phone 200 can automatically resume processing the audio service 1 by the bluetooth headset 100 after the bluetooth headset 100 processes the audio service 2. Thus, after the bluetooth headset 100 finishes processing the audio service 2, the mobile phone 200 can automatically resume processing the audio service 1 by using the bluetooth headset 100 without user operation, thereby improving user experience.

In other embodiments, even if the mobile phone 200 detects that the user timely performs the selection operation of not resuming the originally suspended audio service, the mobile phone 200 can automatically resume the processing of the audio service 1 by the bluetooth headset 100 after the bluetooth headset 100 processes the audio service 2.

Specifically, if the mobile phone 200 receives the second operation of the user on the first prompt message within the first preset time, the second operation is used to trigger the mobile phone 200 not to resume processing the audio service 1 by using the bluetooth headset 100, and the mobile phone 200 automatically resumes processing the audio service 1 by using the bluetooth headset 100 after the bluetooth headset 100 finishes processing the audio service 2. The first prompt information may be displayed on a desktop of the mobile phone 200, or may be displayed on an interface of an audio application, or may be displayed in a drop-down notification management menu of the mobile phone 200. The operation interface of the mobile phone 200 may include the first prompt information and the cancel option button corresponding to the first prompt information at the same time, and the second operation may be a user selection operation of the cancel option button corresponding to the first prompt information, for example, the user clicks the cancel option button. Thus, after the bluetooth headset 100 finishes processing the audio service 2, the mobile phone 200 can automatically resume processing the audio service 1 by using the bluetooth headset 100 without user operation, thereby improving user experience.

In other embodiments, even if the mobile phone 200 detects that the instruction of resuming the originally suspended audio service is not performed, if the tablet 300 is detected to suspend processing the audio service 2 within the first preset duration, the idle bluetooth headset 100 can be fully utilized to resume processing the audio service 1, so as to improve the user experience.

Specifically, if the mobile phone 200 does not receive the operation of the user on the first prompt message within the first preset duration, or if the mobile phone 200 receives the second operation of the user on the first prompt message within the first preset duration, the mobile phone 200 processes the first audio service by using the bluetooth headset after the bluetooth headset pauses the processing of the second audio service; the second operation is used to trigger the mobile phone 200 not to resume the bluetooth headset to process the first audio service.

In other embodiments, no matter whether the mobile phone 200 detects that the user is performing the operation of selecting to resume the originally suspended audio service, the mobile phone 200 may automatically resume processing the audio service 1 by using the bluetooth headset 100 after the bluetooth headset 100 processes the audio service 2 or when the processing of the audio service 2 is suspended, thereby improving the user experience.

Specifically, the mobile phone 200 responds to the second operation of the user on the first prompt message, if the tablet 300 finishes processing the audio service 2 by using the bluetooth headset 100 within the second preset duration, the mobile phone 200 processes the audio service 1 by using the bluetooth headset 100 after the bluetooth headset 100 finishes processing the audio service 2; or the mobile phone 200 responds to the second operation of the user on the first prompt message, if the tablet 300 pauses the processing of the audio service 2 by the Bluetooth headset 100 within the second preset duration, the mobile phone 200 processes the audio service 1 by the Bluetooth headset 100 after the Bluetooth headset 100 pauses the processing of the audio service 2; the second operation is used to trigger the mobile phone 200 not to resume processing the audio service 1 by using the bluetooth headset 100. The second preset time period may be any one of 3 minutes to 4 minutes. For example, the bluetooth headset 100 pauses playing the media of the cell phone 200, playing the conversation of the tablet 300. If the call of the tablet pc 300 is disconnected, for example, the media of the mobile phone 200 is still in a state to be played, and the time when the bluetooth headset 100 pauses playing the media of the mobile phone 200 until the current duration is less than 3 minutes, the process returns to the bluetooth headset 100 playing the media of the mobile phone 200.

In some embodiments, after the bluetooth headset 100 pauses processing the audio service 1, the mobile phone 200 may also automatically process the audio service 1 to be processed, thereby improving the completion of the audio service. After the tablet 300 detects the audio service 2 and requests the bluetooth headset 100 to suspend processing the audio service 1 and processes the audio service 2 by using the bluetooth headset 100, the method further includes the steps of: the mobile phone 200 may mute and suspend the audio service 1, or may process the audio service 1 by using the audio component of the mobile phone 200. The audio component may be a speaker, a plug-in earphone or a receiver. Specifically, if the audio service 1 is a call, a bluetooth recording, a notification, or a system, the audio service may be directly switched to the audio component of the mobile phone 200 to continue the audio service. If audio service 1 is a media type service, it may be paused (e.g., music, video), or muted (e.g., game).

The multimedia framework 303 is further configured to, when receiving an audio service preemption notification (abbreviated as preemption notification in the figure) sent by the audio manager 302, send the audio service preemption notification to the bluetooth module 304.

The bluetooth module 304 is used to support the transfer of various instructions and data. In the embodiment of the present application, the bluetooth headset 100 is configured to support audio data transfer, audio service processing or/and suspension request, audio service preemption notification, and audio service processing status transmission.

Fig. 10 is a schematic diagram of the interaction logic of the modules of a handset 200 preempted audio service when an audio service preemption event occurs, corresponding to fig. 5, according to some embodiments of the application. As shown in fig. 10:

If the mobile phone 200 is playing music by using the bluetooth headset 100, the bluetooth headset 100 receives a music playing request initiated by the tablet 300, and the bluetooth headset 100 determines that the state of the bluetooth headset 100 for processing the audio service is in preemption, then sends a preemption notification to the mobile phone 200, and the bluetooth module 204 receives a preemption event and the state of the bluetooth headset 100 for processing the audio service (abbreviated as headset state).

The bluetooth headset 100 forwards the preemption notification and headset status to the audio manager 202 and multimedia framework 203, respectively. The multimedia framework 303 confirms whether audio service preemption is required according to the service priority of the audio service being processed by the bluetooth headset 100 and the service priority of the audio service initiated by the tablet 300 indicated by the headset state, if so, notifies the music application 3011 to pause playing, and sends the pause playing result to the audio manager 202, and the audio manager 202 displays a "reseize" window under the condition of receiving the pause playing notification.

The audio manager 202, upon receiving the preemption notification, displays a preemption notification window first, where the preemption notification window is used to request whether to mute the own audio service or switch to the own receiver, plug earphone, and speaker to play music to the user, and if it is detected that the user selects any one of the foregoing options, performs a corresponding action according to the content of the option.

Fig. 11 is a schematic diagram of interaction logic for a preempted audio service handset 200 to resume playing music using the bluetooth headset 100, corresponding to fig. 7, according to some embodiments of the application. As shown in fig. 11:

After the tablet pc 300 plays music using the bluetooth headset 100, after detecting that the user clicks the confirm option in the one-button reseize pop-up window, the mobile phone 200 invokes the interface of the multimedia framework 303 to notify the multimedia framework 303 to play music. Then, the multimedia framework 303 notifies the music application 2011 to play music using the bluetooth headset 100. The bluetooth module 204 then notifies the bluetooth headset 100 of the play status. After the bluetooth headset 100 receives the play notification of the tablet pc 300, music of the mobile phone 200 is played, and the tablet pc 300 is notified of a state in which the bluetooth headset 100 processes audio services (abbreviated as headset state).

In other embodiments, corresponding to the application scenario of fig. 2 or fig. 5, if the tablet 300 detects that the user pauses the operation of playing music, the playing of music by the bluetooth headset 100 is paused, and at this time, when the mobile phone 200 determines that the bluetooth headset 100 is in the idle state, the playing of music by the bluetooth headset 100 is automatically resumed. Specifically, referring to fig. 12, fig. 12 shows an interactive logic diagram of the bluetooth headset 100 in an idle state when the tablet 300 pauses in playing music, and the mobile phone 200 resumes playing music using the bluetooth headset 100 according to some embodiments of the present application. As shown in fig. 12: the tablet pc 300 detects that the user pauses the operation of playing music, pauses the operation of playing music using the bluetooth headset 100, and the bluetooth headset 100 is idle, and notifies the mobile phone 200 of a notification of resuming the playing of music (abbreviated as resume notification in the figure) and the headset status. The bluetooth headset 100 forwards a notification of resuming playing music and the headset status to the audio manager 202 and the multimedia framework 203, respectively. The audio manager 202 invokes an interface of the multimedia framework 303, and then the multimedia framework 303 notifies the music application 3011 to play the music.

Fig. 13 is a flow chart of an audio service restoration processing method corresponding to the application scenarios in fig. 1, fig. 2, fig. 5 and fig. 7 according to some embodiments of the present application. As shown in fig. 13, the flow includes the steps of:

131: the bluetooth headset 100 establishes wireless communication channels with the handset 200 and the tablet 300, respectively.

132: The bluetooth headset 100 plays music of the mobile phone 200.

133: The tablet 300 detects the play of music.

In some embodiments, the tablet 300 may detect a user-initiated music service in response to a user playing selected music.

134: The bluetooth headset 100 determines that the audio service priority of music playing the tablet 300 is greater than the audio service priority of music playing the mobile phone 200, requests to pause the music playing of the mobile phone 200, and plays the music of the tablet 300.

In the embodiment of the application, different audio services of the electronic device can correspond to different priorities, and the audio service with higher priority is usually an important and key audio service, and the audio service with higher priority can be preferentially processed by the Bluetooth headset. By way of example, the audio services may include a plurality of types, for example, the audio services may include a call service, a multimedia service, a notification prompt service, and the like. The call service may include playing the voice data of the opposite terminal for the user in the scenes of a phone call (including a phone call in and a phone call out), a video call, an audio call, a voice message, a game or a voice assistant, or collecting the voice data of the user and sending to the opposite terminal, playing an incoming call bell, etc. Multimedia services may include playing music, video, sound recordings, background music for games, text-to-speech sounds, etc. The notification alert service may include play a short message alert tone, push notification alert tone, alarm bell, system sound (e.g., sound when volume is adjusted, shutter sound when shooting, etc.). The priority of the notification prompt service, the multimedia service and the call service are sequentially increased. In other embodiments, the audio service may include more types, and is not particularly limited herein. The priority of the audio service may be preset, or may be set actively by the user, which is not limited herein. For example, the service priority of the call service is greater than the service priority of the multimedia service, which is greater than the service priority of the notification prompt service.

135, The bluetooth headset 100 pauses the playing of music of the mobile phone 200 and plays music of the tablet 300.

136 The bluetooth headset 100 sends a suspension notification message to the handset 200.

137 The mobile phone 200 displays a first prompt message for requesting whether the user resumes playing the music audio service of the mobile phone 200 using the bluetooth headset 100.

138, The mobile phone 200 responds to the confirmation operation of the user on the first prompt information.

The first prompt is used to request the user to determine whether the mobile phone 200 resumes playing music using the bluetooth headset 100.

The first prompt may be a "one key reseize" pop-up window. The determination may be a user clicking on a confirm option in a "one-key reseize" pop-up.

139 The handset 200 requests the bluetooth headset 100 to suspend the bluetooth headset 100 from playing the music of the tablet 300.

In some embodiments, after the mobile phone 200 requests the bluetooth headset 100 to pause the bluetooth headset 100 from playing the music of the tablet 300, the bluetooth headset 100 pauses to play the music of the tablet 300, and after playing the music of the mobile phone 200, the tablet 300 can play the music by using its own speaker, plug-in earphone, receiver, or the like. Specifically, if the audio service 1 is a call, a bluetooth recording, a notification, or a system, the audio service may be directly switched to the audio component of the tablet 300 to continue the audio service. If audio service 1 is a media type service, it may be paused (e.g., music, video), or muted (e.g., game).

In some embodiments, when the tablet 300 is playing music using the bluetooth headset 100 and is preempted by the music playing service initiated by the mobile phone 200, the bluetooth headset 100 will record the music playing state of the mobile phone 200, so that the tablet 300 resumes playing music using the bluetooth headset 100 when the bluetooth headset 100 is released. For example, as shown in fig. 8: the tablet pc 300 detects that the user pauses the operation of playing music, pauses the operation of playing music using the bluetooth headset 100, and the bluetooth headset 100 is idle, and notifies the mobile phone 200 of a notification of resuming the playing of music (abbreviated as resume notification in the figure) and the headset status. The bluetooth headset 100 forwards a notification of resuming playing music and the headset status to the audio manager 202 and the multimedia framework 203, respectively. The audio manager 202 invokes an interface of the multimedia framework 303, and then the multimedia framework 303 notifies the music application 3011 to play the music.

1310, The bluetooth headset 100 plays the music of the mobile phone 200.
