It should be understood that the number of terminal devices, networks and bluetooth headsets in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and bluetooth headsets, as desired for implementation.

With continued reference to fig. 2, a flow 200 of one embodiment of a method for playing audio in accordance with the present disclosure is shown. The method for playing audio comprises the following steps:

in step 201, in response to detecting disconnection of a previously connected bluetooth headset, reason information for characterizing the reason for disconnection of the bluetooth headset is extracted.

In the present embodiment, an execution subject of the method for playing audio (e.g.,

terminal apparatuses

101, 102, 103 shown in fig. 1) may extract cause information for characterizing a cause of disconnection of a previously connected bluetooth headset in response to disconnection from the bluetooth headset detected by a wired connection manner or a wireless connection manner. Wherein, the reason information may include but is not limited to at least one of the following: text, numbers, symbols, images, audio, video. As an example, the reason information may include a number "1" or a number "2", wherein the number "1" may be used to characterize that the reason for the disconnection of the bluetooth headset is a user operation; the number "2" may be used to characterize the disconnection of the bluetooth headset because the distance between the bluetooth headset and the executing body is beyond the range of the bluetooth signal.

It will be appreciated that in practice, the user may operate (e.g. click a bluetooth function activation button) to communicatively couple the bluetooth headset and the execution body. The user can also disconnect the communication connection between the bluetooth headset and the execution main body by operating (for example, clicking a bluetooth function off button). In addition, when the user wears the bluetooth headset to leave the execution main body and moves to the outside of the range of the bluetooth signal sent by the execution main body, the execution main body cannot find the bluetooth headset, and then the execution main body is disconnected with the bluetooth headset.

In this embodiment, when the execution main body detects disconnection of the bluetooth headset, the execution main body may extract reason information for characterizing a reason for disconnection of the bluetooth headset. Specifically, the executing entity may extract the reason information by various methods, for example, the executing entity may continuously detect a user operation, and further, when a disconnection operation of the user is detected (for example, a bluetooth function close button is clicked), disconnect the communication connection with the bluetooth headset, and generate the reason information for representing that the reason for disconnecting the bluetooth headset is the user operation; or, the execution main body may also search a replay parameter recorded in a pre-installed bluetooth protocol and used for indicating a disconnection reason when detecting that the connection with the bluetooth headset is disconnected, and generate reason information based on the replay parameter (for example, the replay parameter may be directly used as the reason information; or the replay parameter may be converted into characters, and the converted characters may be used as the reason information).

In response to detecting the play request for the target audio, it is determined whether the reason for disconnecting the bluetooth headset is a user operation based on the reason information, step 202.

In this embodiment, in the case that the bluetooth headset is disconnected from the execution main body, the execution main body may determine whether the reason why the bluetooth headset is disconnected is a user operation based on the reason information obtained in step 201 in response to detecting the play request for the target audio. Wherein the target audio may be audio to be played.

In particular, the target audio may be an audio for alerting the user, and may be, for example, an incoming call ring tone, an alarm ring tone, or the like. It can be appreciated that there is a need for timely retrieval by a user for audio for alerting the user.

The play request may be for requesting to play the target audio. In practice, the play request may be a request initiated by an application installed in advance on the execution main body, for example, the play request may be a play request initiated by an alarm clock application for an alarm clock ringtone, and specifically, when the current time reaches a time corresponding to a preset alarm clock, the alarm clock application may initiate a play request for the alarm clock ringtone to the execution main body; or, the playing request may be a playing request initiated by the phone application for the incoming call ringtone, and specifically, when receiving the phone call of another user, the phone application may initiate a playing request for the incoming ringtone to the execution main body.

Here, the user operation refers to an operation in which the user actively disconnects the communication connection between the bluetooth headset and the execution main body, for example, clicking a bluetooth function off button. When the user actively disconnects, it can be stated that the user does not have a need to receive audio through the bluetooth headset.

And step 203, in response to determining that the reason for disconnecting the Bluetooth headset is not the user operation, adjusting the current first Bluetooth transmission power to a second Bluetooth transmission power so as to be reconnected with the Bluetooth headset.

In this embodiment, the executing body may determine, in response to determining that the reason for disconnection of the bluetooth headset is not a user operation, a current bluetooth transmission power as the first bluetooth transmission power, and adjust the current first bluetooth transmission power to the second bluetooth transmission power to reconnect with the bluetooth headset. And the second Bluetooth transmitting power is greater than the first Bluetooth transmitting power.

It is understood that when it is determined that the disconnection of the bluetooth headset is not the disconnection instructed by the user through the reason information, it may be determined that the reason for the disconnection is that the distance between the bluetooth headset and the execution main body exceeds the range of the bluetooth signal, and at this time, the user may still have a need to receive the target audio through the bluetooth headset. In order to meet the requirements of users, the embodiment adopts a mode of increasing the range of the bluetooth signal.

Specifically, the range of the bluetooth signal is in direct proportion to the transmission power of the bluetooth signal, and the greater the transmission power, the greater the range. Furthermore, in order to increase the range of the bluetooth signal, the present first bluetooth transmission power may be increased to be the second bluetooth transmission power, so that the distance between the bluetooth headset and the execution main body may be included in the increased range, and the execution main body and the bluetooth headset may reestablish the connection relationship.

It should be noted that, the executing main body may increase the first bluetooth transmission power in various ways, for example, the executing main body may increase the first bluetooth transmission power by a preset multiple, and then use the bluetooth transmission power obtained after the preset multiple is increased as the second bluetooth transmission power; or, a technician may preset a plurality of power levels, each level corresponding to a power value and a range of the bluetooth transmission power, and the higher the level is, the larger the bluetooth transmission power is, the larger the range is. Furthermore, the execution main body may obtain a target level from a plurality of power levels, where the target level is any one level higher than a level corresponding to the first bluetooth transmission power, and the execution main body may use the bluetooth transmission power corresponding to the target level as the second bluetooth transmission power.

And step 204, playing the target audio by using the reconnected Bluetooth headset.

In this embodiment, after the connection relationship is reestablished with the bluetooth headset through step 203, the execution main body may send the target audio to the bluetooth headset, so as to play the target audio by using the bluetooth headset. Further, although the user leaves the execution main body, the user can still receive the target audio through the bluetooth headset.

In some optional implementations of this embodiment, the executing body may adjust the current second bluetooth transmission power to the first bluetooth transmission power in response to detecting that the target audio playing is completed.

It can be understood that, after the target audio is played, the user will not have a need to receive the target audio, and the execution main body does not transmit the target audio to the bluetooth headset any more, and at this time, the execution main body may adjust the second bluetooth transmission power back to the initial first bluetooth transmission power, thereby contributing to reducing power consumption.

With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for playing audio according to the present embodiment. In the application scenario of fig. 3, a handset 301 used by a user may establish a communication connection with a bluetooth headset 302 worn by the user. At a certain moment, the user is away from the mobile phone 301 wearing the bluetooth headset 302, and at this moment, the distance between the bluetooth headset 302 and the mobile phone 301 exceeds the range of the bluetooth signal, which causes the bluetooth headset 302 to be disconnected from the mobile phone 301, and the mobile phone 301 may perform the following steps in response to detecting the disconnection of the bluetooth headset 302:

first, the handset 301 can extract cause information 303 (e.g., "out of range") that characterizes the reason why the bluetooth headset 302 was disconnected. Then, the handset 301 may determine whether the reason why the bluetooth headset 302 is disconnected is a user operation based on the reason information 303 in response to detecting the play request 305 for the target audio 304 (e.g., incoming ringtone). Next, the handset 301 may, in response to determining that the reason for the disconnection of the bluetooth headset 302 is not a user operation, obtain the current bluetooth transmission power as a first bluetooth transmission power 306, and adjust the current first bluetooth transmission power 306 to a second bluetooth transmission power 307 to reconnect with the bluetooth headset 302, wherein the second bluetooth transmission power 307 is greater than the first bluetooth transmission power 306. Finally, the handset 301 can send the target audio 304 to the reconnected bluetooth headset 302 to play the target audio 304 with the reconnected bluetooth headset 302. At this time, even if the user leaves the cellular phone 301, the target audio 304 can be acquired through the bluetooth headset 302.

The method provided by the above embodiment of the present disclosure may determine whether the bluetooth headset is disconnected according to the user operation instruction, and if not, may determine that the bluetooth headset is disconnected according to the user operation instruction, and if a play request for the target audio is detected, the bluetooth headset may increase the range of the bluetooth signal by increasing the bluetooth transmission power, so as to reconnect the bluetooth headset.

With further reference to fig. 4, a flow 400 of yet another embodiment of a method for playing audio is shown. The process 400 of the method for playing audio includes the following steps:

in step 401, in response to detecting disconnection of a previously connected bluetooth headset, reason information for characterizing a reason for disconnection of the bluetooth headset is extracted.

terminal apparatuses

101, 102, 103 shown in fig. 1) may extract cause information for characterizing a cause of disconnection of a previously connected bluetooth headset in response to disconnection from the bluetooth headset detected by a wired connection manner or a wireless connection manner. Wherein, the reason information may include but is not limited to at least one of the following: text, numbers, symbols, images, audio, video.

In response to detecting the play request for the target audio, whether the reason for disconnecting the bluetooth headset is a user operation is determined based on the reason information, step 402.

In this embodiment, in the case where the bluetooth headset is disconnected from the execution main body, the execution main body may determine whether the reason why the bluetooth headset is disconnected is a user operation based on the reason information obtained in step 401 in response to the detection of the play request for the target audio. Wherein the target audio may be audio to be played. The play request may be for requesting to play the target audio.

In step 403, in response to determining that the reason for disconnection of the bluetooth headset is not a user operation, acquiring a time at which the bluetooth headset is disconnected as a first time, and acquiring a time at which the play request is detected as a second time.

In this embodiment, the execution main body may acquire, as the first time, a time at which the bluetooth headset is disconnected and acquire, as the second time, a time at which the playback request is detected, in response to determining that the reason for the disconnection of the bluetooth headset is not the user operation.

Specifically, the execution main body may record a time when the bluetooth headset is disconnected when the disconnection of the bluetooth headset is detected, and record a time when the playback request is detected. Further, when it is determined that the disconnection of the bluetooth headset is not the disconnection instructed by the user, the execution main body may acquire the recorded time when the bluetooth headset is disconnected as the first time, and acquire the recorded time when the playback request is detected as the second time.

And step 404, calculating the difference between the second time and the first time to obtain the disconnection duration.

In this embodiment, based on the first time and the second time obtained in step 403, the executing entity may perform difference calculation on the second time and the first time, and obtain a difference calculation result as the off-duration.

It is to be understood that the disconnection period may represent a period of time that the user leaves the execution subject until the play request is detected.

At step 405, it is determined whether the disconnect time period is less than or equal to a target threshold.

In this embodiment, based on the disconnection period obtained in step 404, the execution subject may determine whether the disconnection period is less than or equal to the target threshold. The target threshold may be a value used to measure whether the user is away temporarily. Specifically, when the disconnection period is less than or equal to the target threshold, it may be considered that the user temporarily leaves the execution subject.

In the present embodiment, the target threshold may be obtained in various ways. As an example, the target threshold may be preset by a technician. For example, the technician may predetermine an exit of less than or equal to 15 minutes as a temporary exit, and further, the technician may set the target threshold to 15 (in minutes).

In some optional implementations of this embodiment, the target threshold may be determined by the execution subject by:

first, a plurality of historical disconnection data of the Bluetooth headset in a target historical time period are acquired.

The target historical time period may be a preset historical time period (for example, 3 months in 2020), or may be a historical time period (for example, three days in the past) with the current time as an end point and the duration of a preset duration. The historical disconnection data may be data generated when the bluetooth headset is disconnected within a target historical time period, and specifically, the historical disconnection data may be used to determine a time length for disconnecting the bluetooth headset. Each historical disconnection data of the plurality of historical disconnection data may correspond to a disconnection of the bluetooth headset.

Then, for the historical disconnection data among the plurality of historical disconnection data, the historical disconnection time period is extracted from the historical disconnection data.

Specifically, the execution main body may extract the historical disconnection time period from the historical disconnection data in various ways. For example, the historical disconnection data may directly record the disconnection duration of the bluetooth headset, and the execution main body may directly determine the recorded duration of the historical disconnection data as the historical disconnection duration; or, the historical disconnection data may record disconnection time and reconnection time, and the execution main body may further perform difference calculation on the reconnection time and the disconnection time recorded in the historical disconnection data, and obtain a difference calculation result as the historical disconnection duration.

Finally, a target threshold is generated based on the extracted plurality of historical disconnection time lengths.

It is to be understood that the execution main body may extract one history disconnection time period for each history disconnection data, and further, may extract a plurality of history disconnection time periods for a plurality of history disconnection data.

Specifically, the execution body may generate the target threshold in various ways based on a plurality of historical disconnection time periods. For example, the execution subject described above may perform an average calculation of a plurality of historical opening time periods, obtaining the calculation result as the target threshold.

In some optional implementations of the embodiment, the execution main body may first select an effective historical disconnection time length from the extracted multiple historical disconnection time lengths, and then generate the target threshold based on the selected effective historical disconnection time length.

Specifically, the execution main body may select the valid history disconnection time length from the plurality of history disconnection time lengths by various methods, for example, the execution main body may determine, as the valid history disconnection time length, a history disconnection time length excluding the longest history disconnection time length and the shortest history disconnection time length from the plurality of history disconnection time lengths.

In some optional implementations of the embodiment, the execution main body may further select, as the valid history disconnection time length, a history disconnection time length that is less than or equal to a preset valid time length from the extracted plurality of history disconnection time lengths.

The preset effective time period may be a time period predetermined by a technician. The historical disconnection corresponding to the historical disconnection period less than or equal to the preset effective period may be regarded as disconnection caused by the user temporarily leaving the execution main body. Furthermore, the target threshold can be used for measuring whether the current leaving of the user is temporary leaving, and the implementation mode can determine the target threshold by using the effective historical disconnection duration corresponding to the temporary leaving of the user, so that the more accurate and reliable target threshold can be determined, and the more accurate and reliable Bluetooth transmission power control can be realized.

Specifically, based on the effective historical disconnection time, the execution subject may generate the target threshold value by using various methods. For example, the execution subject may directly perform an average calculation on the effective historical disconnection time period, and determine the calculation result as the target threshold.

In some optional implementations of this embodiment, the executing entity may generate the target threshold by:

the first step is to distribute the weight to the effective historical disconnection duration.

Specifically, the execution main body may assign a weight to each of the selected effective history disconnection time periods by using various methods.

As an example, for a certain effective history disconnection time length, the execution subject may assign a weight to the effective history disconnection time length based on the number of the effective history disconnection time lengths included in the selected effective history disconnection time length.

For example, the selected valid history disconnect duration includes: 14 minutes, 15 minutes. Then the execution master may determine that one of the three selected valid history disconnection periods is included in the valid history disconnection period of 14 minutes, and then the execution master may assign a weight of 0.333 to the valid history disconnection period (0.333-1/3); for the valid history disconnection period of 15 minutes, if the execution subject determines that two valid history disconnection periods are included in the three selected valid history disconnection periods, the execution subject may assign a weight of 0.667(0.4 — 2/3) to the valid history disconnection period.

In some optional implementations of this embodiment, the executing body may further assign a weight to the selected valid history disconnection duration by:

first, a preset time range set is obtained.

The preset time range set may be a time range set obtained by dividing a preset time period. And the time intervals corresponding to all the preset time ranges in the preset time range set are the same. The preset time period may be a time period predetermined by a technician.

As an example, the preset time period is one day. The execution main body may divide one day by taking two hours as a time interval to obtain twelve preset time ranges, and then the twelve preset time ranges may form a preset time range set.

Then, for historical disconnection data in the plurality of historical disconnection data, determining a preset time range to which the historical disconnection time corresponding to the historical disconnection data belongs from a preset time range set as a preset time range corresponding to the historical disconnection data.

Here, the historical disconnection data may record a time at which the bluetooth headset is disconnected, and the execution main body may determine the time at which the bluetooth headset is disconnected, which is recorded in the historical disconnection data, as the historical disconnection time corresponding to the historical disconnection data.

Specifically, the execution main body may determine the preset time range to which the historical disconnection time corresponding to the historical disconnection data belongs by using various methods.

As an example, the set of preset time ranges includes twelve preset time ranges obtained by dividing one day at intervals of two hours: 0: 00-2: 00), [2: 00-4: 00), [4: 00-6: 00), [6: 00-8: 00), [8: 00-10: 00), [10: 00-12: 00), [12: 00-14: 00), [14: 00-16: 00), [16: 00-18: 00), [18: 00-20: 00), [20: 00-22: 00, and [22: 00-24: 00. And the historical disconnection time corresponding to the historical disconnection data is 12:01, and 12:01 is before 12:00 to 14:00, so that the execution body can determine that the historical disconnection time corresponding to the historical disconnection data belongs to the preset time range of [12: 00-14: 00 ].

Then, the quantity of historical disconnection data corresponding to the preset time range in the preset time range set is determined.

After the preset time range corresponding to each historical disconnection data is determined, the execution main body may count the number of the historical disconnection data corresponding to each preset time range.

Continuing with the example, the execution subject acquires historical disconnection data a, historical disconnection data B, historical disconnection data C, and historical disconnection data D, which correspond to historical disconnection times of 12:01, 12:30, 15:40, and 21:15, respectively. Determining that the historical disconnection data A corresponds to a preset time range [12: 00-14: 00 ] through the steps; historical disconnection data B correspond to a preset time range of 12: 00-14: 00; the historical disconnection data C correspond to a preset time range of (14: 00-16: 00); the historical disconnection data D correspond to a preset time range [20: 00-22: 00 ]. In this step, the execution subject may determine that the amount of historical disconnection data corresponding to a preset time range [12: 00-14: 00) is 2; the number of historical disconnection data corresponding to a preset time range [14: 00-16: 00) is 1; the number of historical disconnection data corresponding to a preset time range [20: 00-22: 00) is 1; the number of historical disconnection data corresponding to other preset time ranges is 0.

Then, based on the number of the corresponding historical disconnection data, a weight is assigned to a preset time range in the preset time range set.

Specifically, the executing agent may assign a weight to the preset time range based on the number of the historical disconnection data, so that the weight of the preset time range with a large number of the corresponding historical disconnection data is large.

Continuing with the above example, the execution subject may assign a weight of 0.5(0.5 is 2/4, where 2 is the number of historical disconnection data corresponding to the preset time range, and 4 is the total number of acquired historical disconnection data) to a preset time range [12: 00-14: 00); distributing a weight of 0.25 to a preset time range of [14: 00-16: 00 ]; distributing a weight of 0.25 to a preset time range of [20: 00-22: 00 ]; and assigning a weight of 0 to the other preset time ranges.

Finally, for the effective historical disconnection duration in the selected effective historical disconnection durations, executing the following steps: determining a preset time range corresponding to historical disconnection data corresponding to the effective historical disconnection duration as a target time range; and determining the weight distributed to the target time range as the weight corresponding to the effective historical disconnection time.

Continuing with the example, for the valid historical open time "14 minutes", the execution subject may take the preset time range [14: 00-16: 00) corresponding to the historical open data a corresponding to the valid historical open time "14 minutes" as the target time range corresponding to the valid historical open time, and further determine the weight 0.25 of the target time range [14: 00-16: 00) as the weight corresponding to the valid historical open time.

After assigning weights to the respective effective history disconnection periods, the execution main body may continue to execute the following second step to obtain the target threshold.

And secondly, performing weighted average operation on the selected effective historical disconnection duration by using the distributed weight to obtain an operation result as a target threshold.

The executing body may determine the target threshold value during the process of processing the current disconnection, or may determine the target threshold value in advance based on the historical disconnection data, and directly acquire the predetermined target threshold value during the process of processing the current disconnection.

And step 406, in response to the disconnection duration being less than or equal to the target threshold, adjusting the current first bluetooth transmission power to a second bluetooth transmission power, so as to reconnect with the bluetooth headset.

In this embodiment, the executing entity may determine, in response to determining that the disconnection duration is less than or equal to the target threshold, a current bluetooth transmission power as a first bluetooth transmission power, and adjust the current first bluetooth transmission power to a second bluetooth transmission power for reconnection with the bluetooth headset. And the second Bluetooth transmitting power is greater than the first Bluetooth transmitting power.

It is understood that when it is determined that the disconnection of the bluetooth headset is not the disconnection instructed by the user through the reason information and the user is just temporarily away from the execution main body as described above, it may be considered that the user still has a need to receive the target audio through the bluetooth headset. And in order to satisfy user's demand, above-mentioned execution main part can be with first bluetooth transmit power adjustment for bigger second bluetooth transmit power to this, can increase the range scope of bluetooth signal, and then can realize above-mentioned execution main part and bluetooth headset's communication connection.

Step 407, playing the target audio by using the reconnected bluetooth headset.

In this embodiment, after the connection relationship is reestablished with the bluetooth headset through step 406, the execution main body may send the target audio to the bluetooth headset, so as to play the target audio by using the bluetooth headset.

Step 401, step 402, and step 407 may be performed in a manner similar to that of step 201, step 202, and step 204 in the foregoing embodiment, respectively, and the above description for step 201, step 202, and step 204 also applies to step 401, step 402, and step 407, and is not repeated here.

As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for playing audio in the present embodiment highlights the steps of determining whether the disconnection duration of the bluetooth headset is less than or equal to the target threshold in response to determining that the reason for the disconnection of the bluetooth headset is not the user operation, and adjusting the current first bluetooth transmission power to the second bluetooth transmission power in response to the disconnection duration being less than or equal to the target threshold to reconnect with the bluetooth headset. Therefore, the scheme described in the embodiment can increase the Bluetooth transmitting power to reconnect the Bluetooth headset when the disconnection of the Bluetooth headset is determined not to be the disconnection instructed by the user operation and the disconnection duration does not exceed the target threshold, so that the reconnection operation can be performed on the disconnection of which the disconnection duration is less than or equal to the target threshold in a targeted manner, the pertinence of reconnection is improved, and the reduction of power consumption is facilitated; moreover, the disconnection duration is less than or equal to the target threshold, which may correspond to a user temporarily being out of range (e.g., going to the toilet), at which time the user generally has a need to receive audio, and therefore, performing the reconnection operation when the disconnection duration is less than or equal to the target threshold may meet the user's need. Furthermore, the solution described in this embodiment can reduce power consumption while satisfying the user requirements.
