Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and in particular to a communication method, apparatus, electronic device, and storage medium. Background Technology

[0002] In VoIP (Voice over Internet Protocol) calls using Bluetooth headsets, after successfully entering call mode, the electronic device transmits audio data to the Bluetooth headset via Bluetooth Synchronous Connection Oriented (SCO). After successfully exiting call mode, the electronic device transmits audio data to the Bluetooth headset via Advanced Audio Distribution Profile (A2DP). However, due to the influence of call application code logic and operating system underlying code logic, entering or exiting call mode requires a certain amount of time. During this time, audio is played through the earpiece or speaker. If the device fails to successfully switch to Bluetooth SCO or A2DP within this time, audio leakage may occur, leading to privacy issues and impacting user experience. Summary of the Invention

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0048] In related technologies, if an electronic device is connected to a Bluetooth headset, when making a VoIP call in a calling application, the following application programming interfaces (APIs) are called to start and end the Bluetooth SCO call: setMode interface, startBluetoothSco interface, and stopBluetoothSco interface. Figure 1 This is a schematic diagram illustrating the implementation of Bluetooth SCO calling according to an exemplary embodiment, such as... Figure 1As shown, at the beginning of a Bluetooth SCO call, the call application calls the `setMode` interface and sets the parameter in this interface to `communication` to enter call mode. Entering call mode takes a certain amount of time. During this time, audio transmission switches from A2DP to the earpiece or speaker. Then, the `startBluetoothSco` interface is called to establish Bluetooth SCO. When Bluetooth SCO is successfully established, audio is transmitted through Bluetooth SCO. If Bluetooth SCO is not successfully established when successfully entering call mode, i.e., the switch to Bluetooth SCO is not successful, audio leakage will occur. At the end of a Bluetooth SCO call, the call application calls the `stopBluetoothSco` interface to shut down Bluetooth SCO, thus closing the audio transmission path of the Bluetooth SCO call. Then, the `setMode` interface is called and the parameter in this interface is set to `normal` to exit call mode. Exiting call mode takes a certain amount of time. After Bluetooth SCO is successfully shut down during this time, audio transmission will switch to the earpiece or speaker. When successfully exiting call mode, A2DP is selected for audio output by default. If SCO is successfully shut down when successfully exiting call mode but A2DP is not successfully selected, i.e., the switch to A2DP is not successful, audio leakage will occur. Therefore, if the user fails to successfully switch to Bluetooth SCO or A2DP within the time required to enter or exit call mode, audio leakage may occur, leading to privacy issues and impacting the user experience.

[0049] In an exemplary embodiment of this disclosure, to overcome the audio leakage problem in related technologies, a call method is provided, comprising: when an electronic device is connected to a Bluetooth audio device, responding to a call trigger operation, entering or exiting a call mode, and switching a Bluetooth audio transmission link, wherein the Bluetooth audio transmission link is used to output the audio of the electronic device; before the Bluetooth audio transmission link switch is successful, if it is determined that the audio of the electronic device is output through a preset audio transmission link, the audio is muted, wherein the preset audio transmission link is a non-Bluetooth audio transmission link; and when the Bluetooth audio transmission link switch is successful, the audio is unmuted. This method, by muting the detected audio output by the preset audio transmission link before the Bluetooth audio transmission link switch is successful, can avoid privacy leaks caused by audio leakage during the Bluetooth audio transmission link switch process, thereby improving the user experience.

[0050] In an exemplary embodiment of this disclosure, a call method is provided. Figure 2 This is a flowchart illustrating a call method according to an exemplary embodiment, such as... Figure 2 As shown, the call method includes the following steps:

[0051] Step S201: When the electronic device is connected to the Bluetooth audio device, in response to the call trigger operation, it enters or exits the call mode and switches the Bluetooth audio transmission link, which is used to output the audio of the electronic device.

[0052] Step S202: Before the Bluetooth audio transmission link is successfully switched, if it is determined that the audio of the electronic device is output through the preset audio transmission link, the audio is muted. The preset audio transmission link is a non-Bluetooth audio transmission link.

[0053] Step S203: When the Bluetooth audio transmission link is successfully switched, the audio is unmuted.

[0054] The call method in this disclosure is applied to electronic devices, including smartphones, tablets, smart IoT devices, smart wearable devices, smart vehicle systems, and other devices with call functions. The application scenario is VoIP call scenario, but it can also be applied to other call scenarios that may cause sound leakage problems.

[0055] In step S201, the Bluetooth audio device refers to another electronic device that establishes a connection with the electronic device via the Bluetooth communication protocol for playing audio, such as a Bluetooth headset, Bluetooth speaker, or other Bluetooth device. The call trigger operation can be any preset operation capable of triggering entry into or exit from call mode. For example, entering call mode is triggered when answering or making a call; exiting call mode is triggered when hanging up or being hung up. In response to the call trigger operation, entering or exiting call mode, in some embodiments, is achieved through a first preset program code, which sets the electronic device to call mode, for example, by setting parameters related to the electronic device's operating mode to "communication"; and exiting call mode is achieved through a second preset program code, which sets the electronic device to non-call mode, for example, by setting parameters related to the electronic device's operating mode to "normal".

[0056] The Bluetooth audio transmission link is used to output audio from the electronic device, including a first audio transmission link and a second audio transmission link, namely Bluetooth SCO and A2DP, respectively. Bluetooth SCO is used to transmit call audio to ensure audio-video synchronization, while A2DP is used to transmit other audio. Therefore, the Bluetooth audio transmission link needs to be switched when entering or exiting call mode. When entering call mode, A2DP is no longer used for audio output; instead, Bluetooth SCO is established, and audio output switches to Bluetooth SCO upon successful establishment. When exiting call mode, since the electronic device defaults to A2DP audio output when connected to a Bluetooth audio device, simply disabling Bluetooth SCO will switch back to A2DP audio output after successfully exiting call mode. In some implementations, Bluetooth SCO is established using a third preset program code and disabling it using a fourth preset program code.

[0057] In some implementations, after entering or exiting call mode, it is determined whether the electronic device supports Bluetooth SCO. If the electronic device does not support Bluetooth SCO, there is no need to switch the Bluetooth audio transmission link or perform subsequent steps; if the electronic device supports Bluetooth SCO, the Bluetooth audio transmission link is switched and subsequent steps are performed.

[0058] In step S202, the preset audio transmission link is a non-Bluetooth audio transmission link, including the earpiece, speaker, and other non-Bluetooth audio output devices of the electronic device. During the process of entering or exiting call mode, before the audio transmission link is successfully switched, the audio will be output via the preset audio transmission link. Therefore, to avoid audio leakage during this period, the audio output method is detected when entering or exiting call mode. If audio is detected being output via the preset audio transmission link, the audio is muted, i.e., the audio output of the electronic device is muted. This audio could be call audio or other media audio from the electronic device. When entering call mode, the time interval from the start of entering call mode to the successful establishment of Bluetooth SCO is considered the period before the Bluetooth audio transmission link is successfully switched; when exiting call mode, the time interval from the successful shutdown of Bluetooth SCO to the output of audio via A2DP is considered the period before the Bluetooth audio transmission link is successfully switched.

[0059] In step S203, upon entering call mode, a Bluetooth SCO is established. Once the Bluetooth SCO is successfully established, audio output switches to the Bluetooth SCO, indicating a successful Bluetooth audio transmission link switch. Upon exiting call mode, the Bluetooth SCO is disabled. Upon successful exit from call mode, audio output switches to A2DP. Therefore, detecting audio output via A2DP confirms a successful Bluetooth audio transmission link switch. Unmute the audio upon successful audio transmission link switch, allowing normal audio output via the switched Bluetooth audio transmission link.

[0060] In an exemplary embodiment of this disclosure, when an electronic device connects to a Bluetooth audio device, it enters or exits call mode in response to a call trigger operation and switches the Bluetooth audio transmission link. Before the Bluetooth audio transmission link switch is successful, if it is determined that the audio of the electronic device is output through a preset audio transmission link, the audio is muted. Upon successful Bluetooth audio transmission link switch, the audio is unmuted. This method, by muting the detected audio output through the preset audio transmission link before successful Bluetooth audio transmission link switch, avoids privacy leaks caused by audio leakage during the Bluetooth audio transmission link switch process, thereby improving the user experience.

[0061] In an exemplary embodiment of this disclosure, a call method is provided. Figure 3 This is a flowchart illustrating a call method according to an exemplary embodiment, such as... Figure 3 As shown, the call method includes the following steps:

[0062] Step S301: The operating system determines that the electronic device is connected to the Bluetooth audio device. In response to the call trigger operation, the target application calls the first program interface to enter the call mode and establishes the first audio transmission link through the first program interface.

[0063] Step S302: Before the Bluetooth audio transmission link is successfully switched, if the operating system determines that the audio of the electronic device is output through the preset audio transmission link, the operating system will mute the audio and set the preset audio transmission link to a non-Bluetooth audio transmission link.

[0064] In step S303, in response to the response message indicating that the Bluetooth audio transmission link has been successfully switched, the audio is unmuted through the operating system.

[0065] In step S301, the operating system determines that the electronic device is connected to the Bluetooth audio device. Compared to related technologies where the connection is determined through a call application, this reduces application-layer workload and thus application maintenance costs. The target application is a call application, such as an application for making or receiving mobile phone calls. The first audio transmission link is Bluetooth SCO, and the first program interface includes program code for entering call mode and program code for establishing Bluetooth SCO. In response to a call trigger operation, the target application calls the first program interface, which in turn calls the program code for entering call mode and the program code for establishing Bluetooth SCO.

[0066] In step S302, before the Bluetooth audio transmission link is successfully switched, the audio output through the preset audio transmission link is detected by the audio policy component in the operating system, and when the audio output through the preset audio transmission link is detected, the audio is muted by the audio policy component.

[0067] In step S303, when entering call mode, if the target application successfully establishes the first audio transmission link by calling the first program interface, that is, when the Bluetooth SCO is successfully established, it means that the Bluetooth audio transmission link has been successfully switched to Bluetooth SCO. At this time, the target application sends a response message to the audio policy component of the operating system. When the audio policy component of the operating system detects the response message that the Bluetooth audio transmission link has been successfully switched, it unmutes the audio.

[0068] In one example, Figure 4 This is a schematic diagram illustrating the start of a call according to an exemplary embodiment, such as... Figure 4 As shown, the target application calls the first program interface API, namely startVoip, to enter call mode and establish Bluetooth SCO through the startSco program code. At the same time as entering call mode, the audio output mode is detected by the audio policy component in the operating system. If the audio output mode is earpiece or speaker, the output audio is muted. When the Bluetooth SCO is successfully established, the target application sends a response message to the audio policy component of the operating system to indicate that the Bluetooth audio transmission link has been switched successfully. The audio policy component of the operating system then unmutes the audio.

[0069] In the exemplary embodiments disclosed herein, the program interface in the related technology is reconstructed so that the call method in this embodiment can be implemented by calling only one program interface, making the execution process simpler, more efficient and convenient, and reducing the maintenance cost of the program interface and application.

[0070] In an exemplary embodiment of this disclosure, a call method is provided. Figure 5 This is a flowchart illustrating a call method according to an exemplary embodiment, such as... Figure 5 As shown, the call method includes the following steps:

[0071] Step S501: The operating system determines that the electronic device is connected to the Bluetooth audio device. In response to the call trigger operation, the target application calls the second program interface to exit the call mode and closes the first audio transmission link through the second program interface.

[0072] Step S502: Before the Bluetooth audio transmission link is successfully switched, if the operating system determines that the audio of the electronic device is output through the preset audio transmission link, the operating system will mute the audio and set the preset audio transmission link to a non-Bluetooth audio transmission link.

[0073] In step S503, in response to the response message indicating that the Bluetooth audio transmission link has been successfully switched, the audio is unmuted through the operating system.

[0074] The specific implementation of step S502 is described in step S302, and will not be repeated here.

[0075] In step S501, the first audio transmission link is Bluetooth SCO, and the second program interface includes program code for exiting call mode and program code for disabling Bluetooth SCO. In response to a call trigger operation, the target application calls the second program interface, which in turn calls the program code for exiting call mode and the program code for disabling the establishment of Bluetooth SCO. Other specific implementation methods are described in step S301 and will not be repeated here.

[0076] In step S503, when exiting the call mode, after the target application successfully shuts down the first audio transmission link by calling the second program interface, that is, after the Bluetooth SCO is successfully shut down, it detects that the audio is output through A2DP, which indicates that the Bluetooth audio transmission link has been successfully switched. At this time, the target application sends a response message to the audio policy component of the operating system. When the audio policy component of the operating system detects the response message that the Bluetooth audio transmission link has been successfully switched, it unmutes the audio.

[0077] In one example, Figure 6 This is a schematic diagram illustrating the end of a call according to an exemplary embodiment, such as... Figure 6 As shown, the target application calls the second program interface API, namely stopVoip, to exit the call mode and shuts down Bluetooth SCO through the stopSco program code. At the same time as Bluetooth SCO is successfully shut down, the audio output mode is detected by the audio policy component in the operating system. If the audio output mode is earpiece or speaker, the output audio is muted. When audio is output through A2DP, the target application sends a response message to the audio policy component of the operating system to indicate that the Bluetooth audio transmission link has been switched successfully. The audio policy component of the operating system then unmutes the audio.

[0078] In the exemplary embodiments disclosed herein, the program interface in the related technology is reconstructed so that the call method in this embodiment can be implemented by calling only one program interface, making the execution process simpler, more efficient and convenient, and reducing the maintenance cost of the program interface and application.

[0079] In related technologies, Figure 7 This is a schematic diagram illustrating the switching of audio output modes according to an exemplary embodiment, such as... Figure 7As shown, when the audio output mode switches from Bluetooth SCO to the earpiece, the call application needs to call the stopBluetoothSco interface; when switching from the earpiece to Bluetooth SCO, the call application needs to call the startBluetoothSco interface; when switching from Bluetooth SCO to the speaker, the call application needs to call both the stopBluetoothSco and setSpeakerphoneOn interfaces, setting the parameter in the setSpeakerphoneOn interface to true; when switching from the speaker to Bluetooth SCO, the call application needs to call both the setSpeakerphoneOn and startBluetoothSco interfaces, setting the parameter in the setSpeakerphoneOn interface to false; when switching from the earpiece to the speaker, the call application needs to call the setSpeakerphoneOn interface, setting the parameter in the setSpeakerphoneOn interface to true; and when switching from the speaker to the earpiece, the call application needs to call the setSpeakerphoneOn interface, setting the parameter in the setSpeakerphoneOn interface to false. The switching between multiple program interfaces makes the audio output mode switching logic very complex, resulting in high maintenance costs for the call application.

[0080] In an exemplary embodiment of this disclosure, the call method further includes the following steps:

[0081] The target application calls a third program interface to set the audio output method based on the target parameters in the third program interface.

[0082] The target application is a calling application, and the audio output methods include earpiece, speaker, and Bluetooth SCO. The third program interface includes program code for setting the Bluetooth SCO output method, program code for setting the speaker output method, and program code for setting the earpiece output method. Different target parameters in the third program interface correspond to different audio output methods. The mapping relationship between target parameters and audio data methods is pre-stored. When it is necessary to switch the audio output method, the target application calls the third program interface and sets the target parameters in the third program interface to the target parameters corresponding to the audio output method to be switched.

[0083] In some implementations, in response to receiving a switching request to switch the output mode from the first target output mode to the second target output mode, the target parameter in the third program interface is updated from the first target parameter to the second target parameter, where the first target parameter corresponds to the first target output mode and the second target parameter corresponds to the second target output mode.

[0084] In one example, Figure 8 This is a schematic diagram illustrating the switching of audio output modes according to an exemplary embodiment, such as... Figure 8 As shown, when the audio output mode is switched to Bluetooth SCO, the target application calls the `setVoipDevice` interface and sets the target parameter in the `setVoipDevice` interface to `sco`, which then calls the `startSco` program code to implement Bluetooth SCO audio output mode. When the audio output mode is switched to speaker, the target application calls the `setVoipDevice` interface and sets the target parameter in the `setVoipDevice` interface to `speaker`, which then calls the `speakerphoneOn` program code to implement speaker audio output mode. If switching from Bluetooth SCO to speaker, the `stopSco` program code is also called to turn off Bluetooth SCO. When the audio output mode is switched to earpiece, the target application calls the `setVoipDevice` interface and sets the target parameter in the `setVoipDevice` interface to `earpiece`. If switching from Bluetooth SCO to earpiece, the `stopSco` program code is called to turn off Bluetooth SCO; if switching from speaker to earpiece, the `speakerphoneOff` program code is called to turn off the speaker.

[0085] In this embodiment, the audio output mode switching is implemented through a program interface. Compared with the audio output mode switching methods in related technologies, the implementation logic is simpler, more efficient and convenient, avoiding the application from executing more complex logic, and reducing the maintenance costs of the application and operating system.

[0086] In an exemplary embodiment of this disclosure, a communication device is provided. Figure 9 This is a block diagram illustrating a communication device according to an exemplary embodiment, such as... Figure 9 As shown, the communication device includes:

[0088] The second processing module 902 is configured to mute the audio if it is determined that the audio is output through a preset audio transmission link before the Bluetooth audio transmission link is successfully switched. The preset audio transmission link is a non-Bluetooth audio transmission link. When the Bluetooth audio transmission link is successfully switched, the audio is unmuted.
