When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, touch strength, time stamp of the touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a mailbox application icon, calling an interface of an application framework layer by a mailbox application, starting the mailbox application, and further starting a display driver by calling a kernel layer to display a functional interface of the mailbox application.

The following describes in detail the scheme provided by the embodiment of the present application with reference to the accompanying drawings.

Fig. 3 is a flowchart of an adjustment method for playing audio based on bluetooth according to an embodiment of the present application, as shown in fig. 3, the method includes:

s301, at a first moment, the audio playing state of the terminal equipment is a first state; the terminal equipment establishes a channel for playing audio in a Bluetooth mode; the Bluetooth communication link of the terminal equipment is provided with a first priority parameter, and the first priority parameter characterizes the priority of the Bluetooth communication link of the terminal equipment at the current real-time moment; the first priority parameter has a priority value at a first time and corresponds to a first state.

Illustratively, the terminal device has bluetooth functionality and Wifi functionality. The terminal device can use both bluetooth and Wifi functions. The terminal equipment is connected with the external equipment through Bluetooth. When the terminal equipment plays music through the external equipment, the priority of the Bluetooth communication link of the terminal equipment can be improved by the terminal equipment, so that the priority of the Bluetooth communication link of the terminal equipment is higher than that of the Wifi communication link of the terminal equipment.

The method comprises the steps that in the process of playing audio, the priority of a Bluetooth communication link of the terminal equipment is higher than that of a Wifi communication link of the terminal equipment; in the process of playing the audio, the terminal equipment does not change the priority, so that the priority of the Bluetooth communication link is kept higher than that of the Wifi communication link. Therefore, more bandwidth and resources can be given to Bluetooth, and the Bluetooth performance of the terminal equipment is further improved.

However, since the terminal device keeps the priority of the bluetooth communication link of the terminal device higher than the priority of the Wifi communication link of the terminal device in the process of playing the audio. Therefore, when the terminal equipment needs to process the service with larger data volume through the Wifi communication link, such as roaming, downloading files and the like, the Wifi function is affected because the terminal equipment determines that the resources on the Wifi communication link are fewer. Moreover, the terminal device may compete for resources of the bluetooth communication link through the Wifi communication link, thereby affecting transmission of bluetooth data, such as bluetooth katon.

In addition, the terminal equipment simultaneously uses a Bluetooth function and a Wifi function; when the terminal equipment is connected with an external device through Bluetooth, if the priority of the Bluetooth communication link of the terminal equipment is higher than that of the Wifi communication link of the terminal equipment, the terminal equipment can compete for the resources of the Bluetooth communication link through the Wifi communication link, and further the transmission of Bluetooth data is affected, such as Bluetooth blocking.

In addition, the terminal equipment simultaneously uses a Bluetooth function and a Wifi function; when the terminal equipment is connected with a plurality of external devices in a Bluetooth mode, the priority of the Bluetooth communication link of the terminal equipment is improved by the terminal equipment to be higher than that of the Wifi communication link of the terminal equipment. Then, when external equipment and terminal equipment disconnect bluetooth connection, only remaining 1 external equipment is connected with terminal equipment through bluetooth mode, and at this moment, terminal equipment's bluetooth communication link's priority is still higher than terminal equipment's Wifi communication link's priority to terminal equipment can compete bluetooth communication link's resource through Wifi communication link, and then influences bluetooth data's transmission, for example bluetooth card is on.

The bluetooth communication link and the Wifi communication link are advanced communication links (Advanced Communication Link, ACL).

In this embodiment, at the first moment, the terminal device determines that the terminal device establishes a channel for playing audio in a bluetooth manner, and it can be known that the terminal device establishes a connection with the external device in the bluetooth manner, and the terminal device plays audio through the external device. Audio, such as time music, video, and the like.

The terminal device may then determine that the audio playing state of the terminal device at the first time is the first state.

The first priority parameter has been configured for the bluetooth communication link of the terminal device; the first priority parameter is used for characterizing the priority of the Bluetooth communication link of the terminal device at the current time instant in real time. The terminal equipment can determine that the audio playing state of the terminal equipment at the first moment is the first state, so that the first priority parameter has the value of priority at the first moment; wherein the first priority parameter has a priority value at the first time and corresponds (matches) with the first state.

When the terminal equipment determines that the audio playing state of the terminal equipment at the first moment is the first state, the terminal equipment directly gives a priority value to the first priority parameter; the value of the priority corresponds (matches) to the first state.

S302, at a second moment, the audio playing state of the terminal equipment is a second state, the second state is different from the first state, and the terminal equipment determines the value of the priority represented by the second priority parameter; wherein the second priority parameter characterizes a target priority of a bluetooth communication link of the terminal device; the value of the priority of the second priority parameter at the second moment corresponds to the second state; the second time is later than the first time.

In one example, the first state and the second state include the following.

First case: the first state is a stop state or a pause state, and the value of the priority level of the first priority level parameter at the first moment is a first value; the second state is a playing state, and the value of the priority level of the second priority level parameter at the second moment is a second value; wherein the second priority parameter characterizes a higher priority at the second time than the first priority parameter characterizes at the first time.

Second case: the first state is a playing state, and the value of the priority level of the first priority level parameter at the first moment is a second value; the second state is a stop state or a pause state, and the value of the priority level of the second priority level parameter at the second moment is the first value; wherein the second priority parameter characterizes a lower priority than the first priority parameter characterizes a lower priority at the first time.

Illustratively, the audio playing state of the terminal device is changed at a second time later than the first time; the terminal device determines that the audio playing state of the terminal device is changed from the first state to a second state, the second state being different from the first state.

Since the bluetooth communication link of the terminal device is provided with a second priority parameter, the second priority parameter characterizes the target priority of the bluetooth communication link of the terminal device. At a second time later than the first time, when the terminal device determines that the audio playing state of the terminal device changes from the first state to the second state, the terminal device can determine the value of the priority characterized by the second priority parameter.

When the terminal equipment determines that the audio playing state of the terminal equipment is changed from the first state to the second state, the terminal equipment directly gives a priority value to the second priority parameter; the value of the priority corresponds (matches) to the second state.

It can be known that the first priority parameter has a value of priority at the first moment; the value of the priority of the first priority parameter at the first moment corresponds to the first state. The second priority parameter has a priority value at the second time, and the priority value of the second priority parameter at the second time corresponds to the second state.

The priority of the bluetooth communication link of the terminal device is not changed immediately in step S302, but steps S304-S306 are performed again to determine whether to change the priority of the bluetooth communication link of the terminal device.

In one example, a first priority parameter and a second priority parameter are configured for the bluetooth communication link, wherein the first priority parameter characterizes a priority of the bluetooth communication link of the terminal device at a current time instant in real time, and the second priority parameter characterizes a target priority of the bluetooth communication link of the terminal device.

At a first moment, the audio playing state of the terminal equipment is in a stop state or a pause state, and the value of the priority level of the first priority level parameter at the first moment is a first value; and the first value corresponds to a first state (stopped state or suspended state). For example, if the audio playing state of the terminal device is a stop state or a pause state, the first value of the first priority parameter at the first time is normal.

Then, at a second time later than the first time, changing the audio playing state of the terminal device from the stopped state or the suspended state to the playing state, wherein the value of the priority level of the second priority level parameter at the second time is a second value; and the second value corresponds to the play state. And the second value characterizes a higher priority than the first value, i.e., the second priority parameter characterizes a higher priority at the second time than the first priority parameter characterizes a higher priority at the first time. For example, if the audio playing state of the terminal device is the playing state, the second value of the second priority parameter at the second time is high.

Thus, at the first moment, the audio playing state of the terminal equipment is in a stop state or a pause state, and the current real-time priority of the Bluetooth communication link of the terminal equipment is a first value; at a second moment, changing the audio playing state of the terminal equipment into a playing state, wherein the target priority of the Bluetooth communication link of the terminal equipment is a second value; the second value characterizes a higher priority than the first value.

The terminal equipment determines the audio playing state of the terminal equipment, and changes the playing state from the stopping state or the pause state; the terminal device needs to increase the priority of the bluetooth communication link of the terminal device. In this embodiment, however, the priority of the bluetooth communication link of the terminal device is not immediately increased in step S302, but steps S304-S306 are performed again to determine whether to increase the priority of the bluetooth communication link of the terminal device.

At the first moment, the audio playing state of the terminal equipment is a playing state, and the value of the priority level of the first priority level parameter at the first moment is a second value; and the second value corresponds to the first state (play state). For example, if the audio playing state of the terminal device is a playing state, the second value of the first priority parameter at the first moment is high.

Then, at a second time later than the first time, changing the audio playing state of the terminal equipment from the playing state to a stopping state or a suspending state, wherein the value of the priority level of the second priority level parameter at the second time is the first value; the second value corresponds to a second state (a stopped state or a suspended state). And the priority characterized by the first value is lower than the priority characterized by the second value, i.e. the priority characterized by the second priority parameter at the second time is lower than the priority characterized by the first priority parameter at the first time. For example, if the audio playing state of the terminal device is a stop state or a pause state, the first value of the second priority parameter at the second time is normal.

Thus, at the first moment, the audio playing state of the terminal equipment is the playing state, and the current real-time priority of the Bluetooth communication link of the terminal equipment is the second value; at a second moment, the audio playing state of the terminal equipment becomes a stop state or a pause state, and the target priority of the Bluetooth communication link of the terminal equipment is a first value; wherein the priority characterized by the first value is lower than the priority characterized by the second value.

The terminal equipment determines the audio playing state of the terminal equipment, and changes the state from the playing state to the stopping state or the pause state; the terminal device needs to decrease the priority of the bluetooth communication link of the terminal device. In this embodiment, however, the priority of the bluetooth communication link of the terminal device is not immediately lowered in step S302, but steps S304-S306 are performed again to determine whether to lower the priority of the bluetooth communication link of the terminal device.

Illustratively, in the "first case" described above, S301 is: at a first moment, the terminal equipment is disconnected with Bluetooth connection between the external equipment, and the audio playing state of the terminal equipment is a first state. The external device is a device for playing the audio of the terminal device.

S302 is: at a second moment, the terminal equipment and the external equipment are connected in a Bluetooth mode, the audio playing state of the terminal equipment is a second state, the second state is different from the first state, and the terminal equipment determines the priority characterized by the second priority parameter.

Alternatively, in the "first case" described above, S301 is: at a first moment, the terminal equipment responds to a first operation of a user and pauses playing of audio in a Bluetooth mode; the audio playing state of the terminal equipment is a first state. Wherein the first operation is for indicating to pause playing audio.

S302 is: at a second moment, the terminal equipment responds to a second operation of the user and starts to play audio in a Bluetooth mode; wherein the second operation is used for indicating to start playing the audio; the audio playing state of the terminal equipment is a second state, the second state is different from the first state, and the terminal equipment determines the priority characterized by the second priority parameter.

In the above "second case", S301 is: at a first moment, the terminal equipment and the external equipment are connected by Bluetooth, and the audio playing state of the terminal equipment is a first state. The external device is a device for playing the audio of the terminal device.

S302 is: at a second moment, the terminal equipment disconnects Bluetooth connection with the external equipment; the audio playing state of the terminal equipment is a second state, the second state is different from the first state, and the terminal equipment determines the priority characterized by the second priority parameter.

Alternatively, in the "second case" described above, S301 is: at a first moment, the terminal equipment responds to a second operation of a user and starts to play audio in a Bluetooth mode; the audio playing state of the terminal equipment is a first state. Wherein the second operation is for indicating to start playing the audio.

S302 is: at a second moment, the terminal equipment responds to the first operation of the user and pauses the playing of the audio in a Bluetooth mode; wherein the first operation is for indicating to pause playing audio; the audio playing state of the terminal equipment is a second state, the second state is different from the first state, and the terminal equipment determines the priority characterized by the second priority parameter.

The bluetooth communication link is illustratively configured with a first priority parameter that characterizes a priority of the bluetooth communication link of the terminal device at a current instant in time and a second priority parameter that characterizes a target priority of the bluetooth communication link of the terminal device.

In one example, the terminal device establishes a connection with the external device through bluetooth, and the terminal device plays audio through the external device. At a first moment, the terminal equipment is disconnected with the Bluetooth connection between the external equipment, the audio playing state of the terminal equipment is in a stop state or a pause state, and the value of the priority level of the first priority level parameter at the first moment is a first value; and the first value corresponds to a first state (stopped state or suspended state). For example, if the audio playing state of the terminal device is a stop state or a pause state, the first value of the first priority parameter at the first time is normal.

Then, at a second moment later than the first moment, the terminal equipment establishes Bluetooth connection with the external equipment again so as to play audio through the external equipment; thus, at the second moment, the audio playing state of the terminal equipment is changed from the stopping state or the suspending state to be the playing state, and then the value of the priority level of the second priority level parameter at the second moment is the second value; and the second value corresponds to the play state. And the second value characterizes a higher priority than the first value, i.e., the second priority parameter characterizes a higher priority at the second time than the first priority parameter characterizes a higher priority at the first time. For example, if the audio playing state of the terminal device is the playing state, the second value of the second priority parameter at the second time is high.

In another example, the terminal device establishes a connection with the external device through bluetooth, and the terminal device plays audio through the external device. At a first moment, the user operates the terminal device, and then inputs a first operation (for example, clicking on audio played by the terminal device or inputting voice for pausing playing into the terminal device) into the terminal device; the terminal equipment detects that the first operation is an operation for indicating to pause playing of the audio, so that the terminal equipment pauses playing of the audio in a Bluetooth mode, the audio playing state of the terminal equipment is a stop state or a pause state, and the value of the priority level of the first priority level parameter at the first moment is a first value; and the first value corresponds to a first state (stopped state or suspended state). For example, if the audio playing state of the terminal device is a stop state or a pause state, the first value of the first priority parameter at the first time is normal.

Then, at a second time later than the first time, the user operates the terminal device, and further inputs a second operation into the terminal device (for example, clicking on the audio played by the terminal device or inputting the voice to start playing into the terminal device); the terminal equipment detects a second operation as an operation for indicating to start playing the audio, and at a second moment, the audio playing state of the terminal equipment is changed from a stop state or a pause state to be the playing state, and then the value of the priority level of the second priority level parameter at the second moment is a second value; and the second value corresponds to the play state. And the second value characterizes a higher priority than the first value, i.e., the second priority parameter characterizes a higher priority at the second time than the first priority parameter characterizes a higher priority at the first time. For example, if the audio playing state of the terminal device is the playing state, the second value of the second priority parameter at the second time is high.

In one example, at a first moment, a bluetooth connection is established between the terminal device and an external device, the terminal device determines that audio is played through the external device, and if the audio playing state of the terminal device is a playing state, the value of the priority level of the first priority level parameter at the first moment is a second value; and the second value corresponds to the first state (play state). For example, if the audio playing state of the terminal device is a playing state, the second value of the first priority parameter at the first moment is high.

Then, at a second time later than the first time, the terminal device disconnects the Bluetooth connection with the external device for playing the audio, the audio playing state of the terminal device is changed from the playing state to the stopping state or the suspending state, and the value of the priority level of the second priority level parameter at the second time is the first value; the second value corresponds to a second state (a stopped state or a suspended state). And the priority characterized by the first value is lower than the priority characterized by the second value, i.e. the priority characterized by the second priority parameter at the second time is lower than the priority characterized by the first priority parameter at the first time. For example, if the audio playing state of the terminal device is a stop state or a pause state, the first value of the second priority parameter at the second time is normal.

In another example, the terminal device has established a bluetooth connection with an external device. At a first moment, the user operates the terminal device, and then inputs a second operation (for example, clicking on the audio played by the terminal device or inputting the voice starting playing into the terminal device) into the terminal device; the terminal equipment detects the second operation as the operation for indicating to start playing the audio, and plays the audio through the external equipment with the Bluetooth connection established. The audio playing state of the terminal equipment is a playing state at the first moment, and the value of the priority level of the first priority level parameter at the first moment is a second value; and the second value corresponds to the first state (play state). For example, if the audio playing state of the terminal device is a playing state, the second value of the first priority parameter at the first moment is high.

Then, at a second time later than the first time, the user operates the terminal device, and further inputs a first operation into the terminal device (for example, clicks on audio played by the terminal device or inputs voice for pausing playing into the terminal device); the terminal equipment pauses the audio playing through the external equipment with the Bluetooth connection established, so that the audio playing state of the terminal equipment is changed from the playing state to the stopping state or the pausing state, and the value of the priority level of the second priority level parameter at the second moment is the first value; the second value corresponds to a second state (a stopped state or a suspended state). And the priority characterized by the first value is lower than the priority characterized by the second value, i.e. the priority characterized by the second priority parameter at the second time is lower than the priority characterized by the first priority parameter at the first time. For example, if the audio playing state of the terminal device is a stop state or a pause state, the first value of the second priority parameter at the second time is normal.

S303, the terminal equipment judges whether the value of the priority of the first priority parameter at the first moment and the value of the priority of the second priority parameter at the second moment are different or not, and whether the number of the equipment connected with the terminal equipment in a Bluetooth mode is larger than the preset number or not.

In one example, the preset number is 1.

Illustratively, after step S302, the terminal device first determines whether the first priority parameter and the second priority parameter are different from each other in the priority level at the first time and the priority level at the second time, that is, whether the real-time priority level of the bluetooth communication link of the terminal device and the target priority level of the bluetooth communication link of the terminal device are different from each other.

And because the terminal equipment can be connected with at least one external equipment through the Bluetooth mode, the terminal equipment can judge whether the number of the equipment connected with the terminal equipment through the Bluetooth mode is larger than the preset number. The preset number may be 1.

S304, when the value of the priority of the first priority parameter at the first moment and the value of the priority of the second priority parameter at the second moment are different, and the number of the devices connected by the terminal device through the Bluetooth mode is larger than the preset number, the terminal device determines the value of the priority of the second priority parameter at the second moment as the value of the first priority parameter.

Illustratively, after step S303, if it is determined that the value of the priority of the first priority parameter at the first time and the value of the priority of the second priority parameter at the second time are different, that is, it is determined that the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are different. And, the terminal device determines that the number of devices connected to the terminal device by the bluetooth mode is greater than a preset number (for example, 1).

And then, the terminal equipment assigns the value of the priority of the second priority parameter at the second moment to the value of the first priority parameter. And further determining the real-time priority of the Bluetooth communication link of the terminal equipment, and changing the value of the priority of the second priority parameter at the second time.

S305, when the value of the priority of the first priority parameter at the first moment and the value of the priority of the second priority parameter at the second moment are the same, and/or the number of the devices connected by the terminal device through the Bluetooth mode is less than or equal to the preset number, the terminal device determines that the value of the first priority parameter is unchanged.

Illustratively, after step S303, if it is determined that the value of the priority of the first priority parameter at the first time and the value of the priority of the second priority parameter at the second time are the same, that is, the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are the same. And/or the terminal equipment determines the number of the equipment connected with the terminal equipment through the Bluetooth mode to be less than or equal to the preset number (for example, 1).

Then, the terminal device does not assign the value of the priority of the second priority parameter at the second time to the value of the first priority parameter. And further determining the real-time priority of the Bluetooth communication link of the terminal equipment, wherein the priority is still the value of the priority of the first priority parameter at the first moment.

For example, the terminal device establishes a connection with the external device through bluetooth, and the terminal device plays audio through the external device. At a first moment, the terminal equipment is disconnected with the Bluetooth connection between the external equipment, the audio playing state of the terminal equipment is in a stop state or a pause state, and the value of the priority level of the first priority level parameter at the first moment is a first value normal.

Then, at a second moment later than the first moment, the terminal equipment establishes Bluetooth connection with the external equipment again so as to play audio through the external equipment; thus, at the second time, when the audio playing state of the terminal device is changed from the stopped state or the suspended state to the playing state, the value of the priority level of the second priority level parameter at the second time is a second value high. The second value representation has a higher priority than the first value representation.

The value of the priority of the first priority parameter at the first time and the value of the priority of the second priority parameter at the second time may be determined to be different, i.e. the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are determined to be different. The number of devices connected to the terminal device by bluetooth is 2. Therefore, the priority of the Bluetooth communication link of the terminal equipment is determined by the terminal equipment and changed into the second value high, and the priority of the Bluetooth communication link of the terminal equipment is further improved, so that the priority of the Bluetooth communication link of the terminal equipment is higher than the priority of the Wifi communication link of the terminal equipment.

Or if it is determined that the value of the priority of the first priority parameter at the first time and the value of the priority of the second priority parameter at the second time are different, that is, the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are different. However, the number of devices to which the terminal device is connected by the bluetooth method is 1. The terminal equipment determines the real-time priority of the Bluetooth communication link of the terminal equipment and still is 'the value normal of the priority of the first priority parameter at the first moment'; the priority of the Bluetooth communication link of the terminal equipment cannot be controlled by the terminal equipment, and the priority is higher than that of the Wifi communication link of the terminal equipment.

For example, the terminal device establishes a connection with the external device through bluetooth, and the terminal device plays audio through the external device. At a first moment, the user operates the terminal device, and then inputs a first operation (for example, clicking on audio played by the terminal device or inputting voice for pausing playing into the terminal device) into the terminal device; the terminal device detects that the first operation indicates to pause the audio playing operation, so that the terminal device pauses the audio playing operation in a Bluetooth mode, the audio playing state of the terminal device is a stop state or a pause state, and the value of the priority level of the first priority level parameter at the first moment is a first value normal.

Then, at a second time later than the first time, the user operates the terminal device, and further inputs a second operation into the terminal device (for example, clicking on the audio played by the terminal device or inputting the voice to start playing into the terminal device); the terminal device detects that the second operation is an operation for indicating to start playing the audio, and at the second time, the audio playing state of the terminal device is changed from the stop state or the pause state to the playing state, and then the value of the priority level of the second priority level parameter at the second time is a second value high. The second value representation has a higher priority than the first value representation.

For example, at a first moment, the terminal device establishes a bluetooth connection with an external device, and if the terminal device determines that the external device plays audio, the audio playing state of the terminal device is a playing state, and the first priority parameter has a priority value of a second value high at the first moment.

Then, at a second time later than the first time, the terminal device disconnects the bluetooth connection with the external device for playing audio, and the audio playing state of the terminal device is changed from the playing state to the stop state or the pause state, so that the value of the priority level of the second priority level parameter at the second time is the first value normal.

The value of the priority of the first priority parameter at the first time and the value of the priority of the second priority parameter at the second time may be determined to be different, i.e. the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are determined to be different. The number of devices connected to the terminal device by bluetooth is 2. Therefore, the priority of the Bluetooth communication link of the terminal equipment is determined by the terminal equipment, and the priority of the Bluetooth communication link of the terminal equipment is changed to the first value normal, so that the priority of the Bluetooth communication link of the terminal equipment is reduced, and the priority of the Bluetooth communication link of the terminal equipment is not higher than the priority of the Wifi communication link of the terminal equipment. For example, the priority of the bluetooth communication link of the terminal device is the same as the priority of the wifi communication link of the terminal device.

Or if it is determined that the value of the priority of the first priority parameter at the first time and the value of the priority of the second priority parameter at the second time are different, that is, the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are different. However, the number of devices to which the terminal device is connected by the bluetooth method is 1. The terminal equipment determines the real-time priority of the Bluetooth communication link of the terminal equipment and still is 'the value high of the priority of the first priority parameter at the first moment'; the terminal device does not adjust the priority of the bluetooth communication link.

For example, the terminal device has established a bluetooth connection with an external device. At a first moment, the user operates the terminal device, and then inputs a second operation (for example, clicking on the audio played by the terminal device or inputting the voice starting playing into the terminal device) into the terminal device; the terminal equipment detects the second operation as the operation for indicating to start playing the audio, and plays the audio through the external equipment with the Bluetooth connection established. And at the first moment, the audio playing state of the terminal equipment is the playing state, and the value of the priority level of the first priority level parameter at the first moment is a second value high.

Then, at a second time later than the first time, the user operates the terminal device, and further inputs a first operation into the terminal device (for example, clicks on audio played by the terminal device or inputs voice for pausing playing into the terminal device); the terminal device pauses playing the audio through the external device with the Bluetooth connection established, so that the audio playing state of the terminal device is changed from the playing state to the stopping state or the pausing state, and the value of the priority level of the second priority level parameter at the second moment is the first value normal.

For example, at a first moment, when the terminal device disconnects an external device to establish a bluetooth connection, the terminal device determines that the external device is not enabled to play audio, and the audio playing state of the terminal device is a pause state, and the first priority parameter has a priority value of a first value normal at the first moment.

Then, at a second time later than the first time, the terminal device switches to another external device to play the audio, and the terminal device establishes a bluetooth connection with the other external device. At the second moment, the audio playing state of the terminal equipment is still the playing state, and the value of the priority level of the second priority level parameter at the second moment is a second value high.

It may be determined that the first priority parameter takes on a different value than the second priority parameter takes on a different value than the first priority parameter, i.e. that the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are different. The number of devices to which the terminal device is simultaneously connected by the bluetooth method is 1.

Therefore, the terminal equipment determines the real-time priority of the Bluetooth communication link of the terminal equipment and is still the value normal of the priority of the first priority parameter at the first moment; the priority of the Bluetooth communication link of the terminal equipment cannot be controlled by the terminal equipment, and the priority is higher than that of the Wifi communication link of the terminal equipment.

In the scheme, in the process, if the priority of the bluetooth communication link of the terminal equipment is determined to be the second value high at the current real-time moment, the priority of the bluetooth communication link of the terminal equipment is higher than the priority of the wifi communication link of the terminal equipment.

In the above process, if the priority of the bluetooth communication link of the terminal device is determined to be the first value normal under the current real-time moment of the terminal device, the priority of the bluetooth communication link of the terminal device is not higher than the priority of the wifi communication link of the terminal device. For example, the priority of the bluetooth communication link of the terminal device is the same as the priority of the wifi communication link of the terminal device.

Fig. 4 is a schematic diagram of software layers of a terminal device according to an embodiment of the present application, and as shown in fig. 4, the terminal device is deployed with an application layer (app), an application framework layer (FW), a system runtime layer (Native), a hardware abstraction layer (Hardware Abstraction Layer, HAL), and a Linux kernel layer (Kenrel).

The application layer is deployed with an audio application for playing audio.

The system runtime layer is deployed with an algorithm module for implementing the process of providing steps S301-S305 in this embodiment.

In this embodiment, by detecting that the music playing state of the terminal device changes, it is determined whether the real-time priority of the bluetooth communication link of the terminal device and the target priority of the bluetooth communication link of the terminal device are different, and whether the number of devices connected to the terminal device by the bluetooth mode is greater than a preset number. If the real-time priority of the Bluetooth communication link of the terminal equipment and the target priority of the Bluetooth communication link of the terminal equipment are different and the number of the equipment connected by the terminal equipment in a Bluetooth mode is larger than the preset number, the real-time priority of the Bluetooth communication link of the terminal equipment is determined to be changed into the target priority of the Bluetooth communication link of the terminal equipment. For example, the priority of the bluetooth communication link of the terminal device is made higher than the priority of the Wifi communication link of the terminal device, so that the stability of playing music through the bluetooth communication link can be ensured. Or the priority of the Bluetooth communication link of the terminal equipment is not higher than the priority of the Wifi communication link of the terminal equipment, so that the transmission of the Bluetooth communication link and the Wifi communication link is not influenced.

If the real-time priority of the Bluetooth communication link of the terminal equipment and the target priority of the Bluetooth communication link of the terminal equipment are the same, and/or the number of the equipment connected by the terminal equipment in a Bluetooth mode is less than or equal to the preset number, determining that the real-time priority of the Bluetooth communication link of the terminal equipment is not adjusted; for example, the priority of the bluetooth communication link of the terminal device is not made higher than the priority of the Wifi communication link of the terminal device. Therefore, when only 1 external device is connected with the terminal device in order to play audio through a Bluetooth mode, the priority of the Bluetooth communication link of the terminal device is not enabled to be higher than that of the Wifi communication link of the terminal device, and therefore the terminal device avoids the Wifi communication link competing for resources of the Bluetooth communication link and avoids affecting transmission of Bluetooth data.

The scheme of the embodiment avoids the problem that the communication link competes for resources seriously. The communication influence on the Bluetooth communication mode and the wireless local area network communication mode is reduced.
