Description

Call control method, electronic device, computer readable storage medium and chip system

Technical Field

The embodiment of the application relates to the technical field of electronic equipment, in particular to a call control method and electronic equipment.

Background

With the development of electronic technology, vehicle-mounted devices are installed in most vehicles, and the vehicle-mounted devices can establish a bluetooth (bluetooth) connection with electronic devices (such as mobile phones, tablet computers or smart watches). After the vehicle-mounted device and the electronic device establish the Bluetooth connection, the vehicle-mounted device can output audio data played in the electronic device, and the audio data cannot be output in the electronic device. For example, take the case that a mobile phone receives an incoming call. In response to a call answering operation by a user on the mobile phone, the mobile phone may transmit voice data to the in-vehicle device through a Synchronous Connection Ordered (SCO) link, and play voice content by the in-vehicle device. However, when the vehicle-mounted device plays the voice content, the voice content is played outside in a hands-free mode, and privacy of the user may be revealed.

In the current technical scheme, in order to avoid revealing privacy of a user, under the condition that the user triggers to answer an incoming call through a mobile phone, the mobile phone transmits voice data to the vehicle-mounted equipment through the SCO. Thereafter, the onboard device may disconnect the SCO connection. After the SCO connection of the vehicle-mounted equipment is disconnected, the mobile phone can play voice content.

However, it takes a certain time for the in-vehicle device to disconnect from the cellular phone. In the process of disconnecting the vehicle-mounted equipment and the mobile phone, the vehicle-mounted equipment and the mobile phone cannot play the voice content. This may cause the user to miss part of the speech content, which may affect the user experience.

Disclosure of Invention

The application provides a call control method and electronic equipment, which can ensure that a user can answer complete voice content and improve the use experience of the user.

In a first aspect, the present application provides a method for controlling a call, which is applied to an electronic device. The electronic equipment stores a blacklist, the blacklist comprises a plurality of preset vehicle-mounted equipment identifications, and the preset vehicle-mounted equipment identifications are identifications which do not support the vehicle-mounted equipment for voice transmission under the condition that a user triggers to answer an incoming call through the electronic equipment.

According to the method, the electronic equipment and the vehicle-mounted equipment are connected through Bluetooth, the electronic equipment can obtain the first equipment identification, and the first equipment identification is the identification of the vehicle-mounted equipment. And then, the electronic equipment receives the incoming call, plays the incoming call ringtone to remind the user of the incoming call, and sends an incoming call instruction to the vehicle-mounted equipment. Then, the electronic device can receive a first operation of the user, wherein the first operation is used for triggering answering of the incoming call. Responding to the first operation, if the plurality of preset vehicle-mounted device identifications comprise a first device identification, the electronic device plays the voice content through the electronic device or a first Bluetooth device, and the first Bluetooth device is a Bluetooth device which is connected with the electronic device.

It can be understood that, if the electronic device determines that the first device identifier is in the blacklist, it may be determined that the in-vehicle device does not support voice transmission in a case where the user triggers to answer the incoming call through the electronic device. Therefore, the electronic equipment can directly play the voice content through the electronic equipment or the first Bluetooth equipment. Therefore, the situation that the voice content is not played by the vehicle-mounted equipment and the electronic equipment can be avoided, the situation that a user can answer the complete voice content is guaranteed, and the use experience of the user is improved.

If the plurality of preset vehicle-mounted equipment identifications do not include the first equipment identification, the electronic equipment adds the first equipment identification to the blacklist according to the time consumed by releasing the synchronous connection between the electronic equipment and the vehicle-mounted equipment.

It can be appreciated that the electronic device adds the first device identification to the blacklist based on a length of time it takes to release the synchronization connection. Therefore, when the electronic equipment is connected with the vehicle-mounted equipment again, whether the vehicle-mounted equipment supports voice transmission under the condition that a user triggers to answer the incoming call through the electronic equipment can be determined according to the list. Therefore, the situation that the vehicle-mounted equipment and the electronic equipment do not play the voice content is avoided, the situation that a user can answer the complete voice content is guaranteed, and the use experience of the user is improved.

With reference to the first aspect, in a possible design manner, the electronic device may record a first time and a second time, where the first time is a time when the electronic device receives the first operation, and the second time is a time when the electronic device releases the synchronous connection for the first time after receiving the first operation. The electronic device may calculate a difference between the first time and the second time to obtain a first target difference. And if the first target difference value is smaller than the preset time threshold value, the electronic equipment establishes synchronous connection with the vehicle-mounted equipment again, and records third time, wherein the third time is the time for establishing synchronous connection for the second time after the electronic equipment receives the first operation. After that, the electronic device may release the synchronous connection with the in-vehicle device, and record a fourth time when the electronic device releases the synchronous connection for the second time after receiving the first operation. Then, the electronic device may calculate a difference between the third time and the fourth time to obtain a second target difference. And if the second target difference value is smaller than the preset time threshold value, the electronic equipment adds the first equipment identifier to the blacklist.

It should be noted that the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, or the vehicle-mounted device is abnormal, which may cause the synchronous connection to be released. Therefore, in order to determine that the vehicle-mounted device releases the synchronous connection due to the fact that voice transmission is not supported when the user triggers to answer the incoming call through the electronic device, the electronic device may set a preset time threshold. In general, the time duration consumed for releasing the synchronous connection due to the occurrence of the abnormality of the vehicle-mounted device is longer than the time duration consumed for releasing the synchronous connection due to the fact that the vehicle-mounted device does not support voice transmission under the condition that a user triggers to answer an incoming call through the electronic device.

It can be understood that the first target difference and the second target difference are both smaller than the preset time threshold, which indicates that the time period consumed for releasing the synchronous connection is shorter. Therefore, the synchronous connection is released only when the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment, namely the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment. And the time consumed by releasing the synchronous connection is compared twice, so that whether the vehicle-mounted equipment supports voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment can be more accurately determined, and the accuracy of the blacklist is further improved.

With reference to the first aspect, in another possible design, the electronic device plays the voice content through the electronic device or the first bluetooth device.

It can be understood that after the electronic device releases the synchronous connection with the vehicle-mounted device, the electronic device can play the voice content through the electronic device or the first bluetooth device. Therefore, the user can be ensured to listen to the voice content.

With reference to the first aspect, in another possible design manner, if the first target difference is greater than the preset time threshold, the electronic device plays the voice content through the electronic device or the first bluetooth device.

It will be appreciated that the first target difference value is greater than the predetermined time threshold, indicating that it takes a longer time to release the synchronization connection. Therefore, the method can determine that the synchronous connection is not released by voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment. The electronic equipment can play the voice content through the electronic equipment or the first Bluetooth equipment, and therefore the user can be guaranteed to answer the voice content.

In another possible design, in combination with the first aspect, the electronic device supports ring tone synchronization. The electronic equipment establishes synchronous connection with the vehicle-mounted equipment. The electronic equipment transmits the incoming call ringtone to the vehicle-mounted equipment through synchronous connection, and instructs the vehicle-mounted equipment to play the incoming ringtone to remind the user of the incoming call. Then, the electronic device releases the synchronous connection with the in-vehicle device.

With reference to the first aspect, in another possible design, the electronic device does not support ring synchronization. The electronic equipment establishes synchronous connection with the vehicle-mounted equipment. After that, the electronic apparatus releases the synchronous connection with the in-vehicle apparatus.

With reference to the first aspect, in another possible design manner, if an identifier that is the same as the first device identifier exists in the plurality of preset vehicle-mounted device identifiers, and the time duration for maintaining the synchronous connection between the electronic device and the vehicle-mounted device is longer than a preset time duration, the electronic device deletes the first device identifier from the blacklist.

It can be understood that if the synchronous connection is not released between the electronic device and the vehicle-mounted device within the preset time after the electronic device receives the first operation, it indicates that the vehicle-mounted device supports voice transmission in the case that the user answers the incoming call by triggering the electronic device. Thus, the electronic device may delete the first device identification from the blacklist.

With reference to the first aspect, in another possible design, the electronic device establishes bluetooth connections with a plurality of bluetooth devices, where the plurality of bluetooth devices includes an in-vehicle device and other bluetooth devices except the in-vehicle device. The electronic equipment can play the voice content through the first Bluetooth equipment, and the first Bluetooth equipment is any one of other Bluetooth equipment.

It can be understood that, under the condition that the electronic device is connected with other bluetooth devices except the vehicle-mounted device, if the vehicle-mounted device does not support voice transmission under the condition that a user triggers to answer an incoming call through the electronic device, the electronic device can play voice contents through the first bluetooth device. Therefore, the method and the device can ensure that the user can answer complete voice content, and the user does not need to hold the electronic equipment for communication, so that the use experience of the user is improved.

In combination with the first aspect, in another possible design manner, if the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, the electronic device may display a first prompt message for prompting that the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device.

It can be understood that the electronic device displays the first prompt message, so that the user can know the reason why the voice content is not played by the vehicle-mounted device. Therefore, the confusion of the user in the using process can be reduced, and the using experience of the user is improved.

In a second aspect, the present application provides a method for controlling a call, which is applied to an electronic device.

According to the method, the electronic equipment and the vehicle-mounted equipment are connected through Bluetooth. The electronic equipment can receive a Bluetooth support function (BRSF) message from the vehicle-mounted equipment, wherein the BRSF message comprises first indication information, and the first indication information is used for indicating whether the vehicle-mounted equipment supports voice transmission under the condition that a user triggers to answer an incoming call through the electronic equipment. And then, the electronic equipment receives the incoming call, plays the incoming call ringtone to remind the user of the incoming call, and sends an incoming call instruction to the vehicle-mounted equipment. Then, the electronic device can receive a first operation of the user, wherein the first operation is used for triggering answering of the incoming call. Responding to the first operation, if the first indication information indicates that the vehicle-mounted equipment supports voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment, the electronic equipment plays voice content through the vehicle-mounted equipment. If the first indication information indicates that the vehicle-mounted device does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, the electronic device can play voice contents through the electronic device or a first Bluetooth device, and the first Bluetooth device is a Bluetooth device connected with the electronic device.

It can be understood that, after receiving the BRSF message, the electronic device can determine whether the in-vehicle device supports voice transmission in a case where the user triggers answering of the incoming call through the electronic device. If the vehicle-mounted device does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, the electronic device or the first Bluetooth device can directly play voice content. Therefore, the method and the device can ensure that the user can listen to the complete voice content, and improve the use experience of the user. If the vehicle-mounted equipment supports voice transmission under the condition that a user triggers to answer the incoming call through the electronic equipment, the vehicle-mounted equipment can directly play voice content. Therefore, the user can be guaranteed to hear the complete voice content, and the use experience of the user is improved.

With reference to the second aspect, in one possible design manner, the first indication information includes: a first value or a second value; the first value is used for indicating that the vehicle-mounted equipment supports voice transmission under the condition that a user triggers to answer the incoming call through the electronic equipment, and the second value is used for indicating that the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment.

In combination with the second aspect, in another possible design manner, the electronic device supports incoming call ringtone synchronization, where the incoming ringtone synchronization is a function of synchronizing an incoming ringtone from the electronic device to the vehicle-mounted device. The electronic device may send a synchronization request message to the in-vehicle device, where the synchronization request message is used to request establishment of a synchronous connection between the electronic device and the in-vehicle device. The electronic device may receive a synchronization response message from the in-vehicle device, the synchronization response message indicating that a synchronization connection has been established. And then, the electronic equipment can transmit the incoming call ringtone to the vehicle-mounted equipment through synchronous connection and instruct the vehicle-mounted equipment to play the incoming ringtone to remind the user of the incoming call.

With reference to the second aspect, in another possible design manner, the electronic device may send the voice data to the vehicle-mounted device through synchronous connection, and instruct the vehicle-mounted device to play the voice content corresponding to the voice data.

With reference to the second aspect, in another possible design manner, the electronic device may send a release request message to the vehicle-mounted device, where the release request message is used to instruct to release the synchronous connection. The electronic equipment receives a release response message from the vehicle-mounted equipment, wherein the release response message is used for indicating that the synchronous connection is released.

In combination with the second aspect, in another possible design, the electronic device does not support ring synchronization. The electronic equipment sends a synchronization request message to the vehicle-mounted equipment, wherein the synchronization request message is used for requesting to establish synchronous connection between the electronic equipment and the vehicle-mounted equipment. The electronic equipment receives a synchronization response message from the vehicle-mounted equipment, wherein the synchronization response message is used for indicating that the synchronization connection is established.

Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "e.g.," is intended to present concepts in a concrete fashion.

In order to facilitate understanding of the technical solutions of the present application, prior to describing the call control method in the embodiments of the present application in detail, a description of a conventional technology is provided.

With the development of electronic technology, most vehicles are equipped with vehicle-mounted equipment, and the vehicle-mounted equipment can be wirelessly connected with the electronic equipment through Bluetooth. After the vehicle-mounted device and the electronic device establish the Bluetooth connection, the vehicle-mounted device can output audio data played in the electronic device, and the audio data cannot be output in the electronic device. However, when the vehicle-mounted device plays the voice content, the voice content is played in a hands-free mode, and privacy of the user may be leaked.

In the conventional technology, in a case where the vehicle-mounted device establishes a bluetooth connection with the electronic device, the electronic device may synchronize a voice content to the vehicle-mounted device in response to a phone answering operation performed by a user on the electronic device. Illustratively, as shown in fig. 1 (a), after the electronic device receives an incoming call, an incoming call interface 101 may be displayed, and the incoming call interface 101 may include an answer button 103. In response to an operation (the operation may be clicking, long-pressing, sliding, etc., for example, the operation is operation a) of the user on the listen button 103, the electronic device may synchronize voice data to the in-vehicle device through the SCO. The in-vehicle apparatus may display the call interface 102 shown in (b) in fig. 1. If the vehicle-mounted equipment does not support playing of the voice content, the vehicle-mounted equipment can release SCO connection, namely, SCO connection established between the vehicle-mounted equipment and the electronic equipment is actively disconnected. Specifically, after the vehicle-mounted device receives the voice data from the electronic device, if the vehicle-mounted device does not support playing of the voice content, the vehicle-mounted device may send a disconnection request to the electronic device, where the disconnection request is used to instruct to disconnect the SCO connection with the electronic device. After that, the electronic device receives the disconnection request, and may send a disconnection message to the vehicle-mounted device, where the disconnection message is used to indicate that the SCO connection between the electronic device and the vehicle-mounted device has been successfully disconnected. Furthermore, the vehicle-mounted device releases the SCO connection when the vehicle-mounted device is abnormal. Therefore, the electronic device may re-establish the SCO connection with the vehicle-mounted device to ensure that data can be synchronized between the electronic device and the vehicle-mounted device. As such, the onboard device may release the SCO connection multiple times. After the SCO connection is released by the vehicle-mounted equipment once or for multiple times, the electronic equipment does not synchronize voice data to the vehicle-mounted equipment, and the electronic equipment can play voice content.

However, during the process that the vehicle-mounted device releases the SCO connection (or the process that the electronic device reestablishes the SCO connection), the electronic device still synchronizes the voice data to the vehicle-mounted device. In addition, in the process that the vehicle-mounted device releases the SCO connection (or the process that the electronic device reestablishes the SCO connection), both the electronic device and the vehicle-mounted device cannot play the voice content. This may cause the user to miss part of the speech content, which may affect the user experience.

Therefore, the embodiment of the application provides a call control method. The method can be applied to the situation that the electronic equipment answers the incoming call when the electronic equipment and the vehicle-mounted equipment establish the Bluetooth connection. In the method, in response to the answering operation of the user on the electronic equipment, the electronic equipment can determine whether the vehicle-mounted equipment supports voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment. If the vehicle-mounted device supports voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, the electronic device can determine that the vehicle-mounted device plays the voice content. Therefore, after the electronic equipment triggers to answer the incoming call, the vehicle-mounted equipment can directly play the voice content. Therefore, the method and the device can ensure that the user can listen to the complete voice content, and improve the use experience of the user. Moreover, the user does not need to communicate through the electronic equipment, so that the communication of the user is more convenient.

If the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment, the electronic equipment can determine that the voice content is played by the electronic equipment. That is to say, after the electronic device triggers to answer the incoming call, the electronic device does not synchronize the voice data with the vehicle-mounted device, and the electronic device can directly play the voice content. Therefore, the method and the device can ensure that the user can listen to the complete voice content, and improve the use experience of the user.

For example, the electronic device in the embodiment of the present application may be a tablet computer, a mobile phone, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR), a Virtual Reality (VR) device, and the like, and the embodiment of the present application does not particularly limit the specific form of the electronic device.

The execution main body of the method for controlling the call provided by the application can be a control device of the call, and the execution device can be the electronic equipment shown in fig. 2. Meanwhile, the execution device may also be a Central Processing Unit (CPU) of the electronic device, or a control module for controlling a call in the electronic device.

A memory may also be provided in processor 210 for storing instructions and data. In some embodiments, the memory in the processor 210 is a cache memory. The memory may hold instructions or data that have just been used or recycled by processor 210. If the processor 210 needs to use the instruction or data again, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor 210, thereby increasing the efficiency of the system.

It is to be understood that the structure illustrated in the present embodiment does not specifically limit the mobile phone 200. In other embodiments, cell phone 200 may include more or fewer components than shown, or combine certain components, or split certain components, or a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

Please refer to fig. 3, which is a schematic diagram of a hardware structure of an in-vehicle device according to an embodiment of the present application. As shown in fig. 3, the in-vehicle apparatus 300 may include: a processor 310, a memory 320, a sensor 330, a wireless communication module 340, a receiver 350, and a microphone 360.

The memory 320 may be used to store application program codes, such as application program codes for enabling the in-vehicle device 300 to perform pairing connection with the electronic device (such as the mobile phone 200). The processor 310 may control and execute the application program codes to realize the functions of the in-vehicle device 300 in the embodiment of the present application.

The memory 320 may further store a bluetooth address for uniquely identifying the vehicle-mounted device, and the memory 320 may further store connection data of an electronic device that has been successfully paired with the vehicle-mounted device before. For example, the connection data may be a bluetooth address of the electronic device successfully paired with the in-vehicle device. Based on the connection data, the in-vehicle device can be automatically paired with the electronic device without configuring a connection therebetween, such as performing validity verification or the like. The bluetooth address may be a Media Access Control (MAC) address.

The sensor 330 may include a touch sensor for detecting a touch operation of a user. In some embodiments, the vehicle-mounted device may further include a fingerprint sensor for detecting a fingerprint of the user, identifying an identity of the user, and the like. In other embodiments, the vehicle-mounted device may further include an ambient light sensor, and some parameters, such as volume, may be adaptively adjusted according to the perceived brightness of the ambient light.

The wireless communication module 340 is configured to support short-range data exchange between the in-vehicle device 300 and various electronic devices, such as the mobile phone 200. In some embodiments, the wireless communication module 340 may be a bluetooth transceiver or a Radio Frequency (RF) circuit. The vehicle-mounted device 300 can establish a wireless connection with the mobile phone 200 through the bluetooth transceiver to realize short-distance data exchange between the two.

At least one receiver 350, which may also be referred to as a "headset," may be used to convert the electrical audio signals into sound signals and play them.

At least one microphone 360, which may also be referred to as a "microphone," is used to convert sound signals into electrical audio signals. For example, when the in-vehicle device 300 is used as the audio input device of the mobile phone 200, the microphone 360 may collect the voice signal of the user and convert the voice signal into an audio electrical signal during the process of speaking (such as a call or a voice message). The audio electrical signal is the audio data in the embodiment of the present application. In some embodiments, the microphone 360 may be a feed-forward microphone.

It is to be understood that the illustrated structure of the embodiment of the present application does not constitute a specific limitation to the in-vehicle apparatus 300. It may have more or fewer components than shown in fig. 3, may combine two or more components, or may have a different configuration of components. For example, the in-vehicle device 300 may further include a display screen (which may display an application icon, a call interface, and the like). The various components shown in fig. 3 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing or application specific integrated circuits.

The methods in the following embodiments may be implemented in both the electronic apparatus and the in-vehicle apparatus having the above-described hardware structures.

An embodiment of the present application provides a method for controlling a call, and as shown in fig. 4, the method for controlling a call may include S401 to S406.

S401, the electronic equipment acquires first indication information.

The first indication information is used for indicating whether the vehicle-mounted equipment supports voice transmission under the condition that a user triggers to answer the incoming call through the electronic equipment. The embodiment of the present application does not limit the transmission manner. For example, the electronic device may perform voice transmission with the in-vehicle device through the SCO. For another example, the electronic device may use an Extended Synchronous Connection Organized (ESCO) for voice transmission with the in-vehicle device.

It should be noted that, the triggering of answering the incoming call by the user through the electronic device means that, when the electronic device receives the incoming call, the electronic device receives an incoming call answering operation of the user, and the incoming call answering operation is used for triggering answering the incoming call. Illustratively, as shown in fig. 1 (a), when the electronic device receives an incoming call, the electronic device may receive an operation of the answer button 103 by the user. That is, the scenario in fig. 1 (a) is that the user triggers to answer the incoming call through the electronic device.

It should be noted that the vehicle-mounted device receives the operation of answering the incoming call of the user, and the user is not considered to be triggered to answer the incoming call through the electronic device.

In the embodiment of the application, the electronic device can acquire the first indication information in the process of establishing the Bluetooth connection between the electronic device and the vehicle-mounted device.

In one possible implementation manner, the first indication information is stored in the vehicle-mounted device. In the process of establishing the bluetooth connection between the electronic device and the vehicle-mounted device, the vehicle-mounted device may send the first indication information to the electronic device. Thereafter, the electronic device may receive the first indication information from the electronic device.

As shown in FIG. 5, S401 may include S501-S502.

S501, the vehicle-mounted device can send a Bluetooth support function message to the electronic device.

Wherein, the first Bluetooth Supported Features (BRSF) message carries the first indication information. The BRSF message is used to indicate the functional characteristics that the in-vehicle device can support. For example, the functional characteristics that the in-vehicle device can support may include: the vehicle-mounted equipment supports voice transmission under the condition that a user triggers to answer an incoming call through the electronic equipment, supports three-party conversation and the like.

In one possible implementation manner, during the process of establishing the bluetooth connection between the electronic device and the vehicle-mounted device, the vehicle-mounted device may send a BRSF message to the electronic device. For example, during a process (e.g., service Level Connection (SLC)) in which the electronic device establishes a bluetooth Hands-Free Profile (HFP) Connection with the in-vehicle device, the in-vehicle device may send a first BRSF command (i.e., a BRSF message) to the electronic device, where the first BRSF command carries first indication information in a BitMap format. For example, the first BRSF command may be "AT + BRSF = < HF supported feeds >".

In one possible design, the first indication information may occupy at least one bit in the BitMap. For example, the first indication information may occupy one bit in the BitMap (i.e., the first indication information is 1 bit). For another example, the first indication information may occupy three bits in the BitMap (i.e., the first indication information is 3 bits). The following description is given of an embodiment of the present application by taking an example in which the first indication information occupies one bit in the BitMap. Under the condition that the first indication information occupies one bit in the BitMap, the first indication information can be located in any one bit in reserved bits of the BitMap, and the reserved bits of the BitMap are used for indicating unoccupied bits. That is to say, the bit occupied by the first indication information is not limited in the embodiment of the present application. Illustratively, suppose the reserved bits of the BitMap include the 13 th bit in the BitMap through the 32 th bit in the BitMap. The first indication information may be located at the 13 th bit in the BitMap. The first indication information may also be located at the 15 th bit in the BitMap. The first indication information may also be located at the 30 th bit in the BitMap.

S502, the electronic device receives the Bluetooth support function message from the vehicle-mounted device.

Optionally, the electronic device receives the BRSF message from the vehicle-mounted device, and may send a first response message to the vehicle-mounted device. The first response message is used for indicating that the electronic equipment successfully receives the BRSF message. Optionally, the electronic device may send a BRSF command to the vehicle-mounted device, where the BRSF command is used to indicate functions that the electronic device can support. For example, the functional features that an electronic device is capable of supporting may include: the electronic equipment supports incoming call ringing, the electronic equipment supports three-party call and the like.

S402, the electronic equipment receives an incoming call.

In some embodiments, the electronic device receives an incoming call, and may play an incoming call ring to alert the incoming call (e.g., (a) of fig. 1).

S403, the electronic equipment receives a first operation of the user.

The first operation is used for triggering answering of the incoming call. The first operation is an operation acting on the electronic device (operation a shown in (a) in fig. 1). The embodiment of the present application does not limit the first operation. For example, the first operation may be a sliding operation. For another example, the first operation may be a click operation. For another example, the first operation may be a long press operation.

In the embodiment of the application, after the electronic device receives the incoming call, the user can input the first operation to the electronic device. The electronic device may receive a first operation by a user.

S404, responding to the first operation, the electronic equipment determines whether the vehicle-mounted equipment supports voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment or not according to the first indication information.

In some embodiments, if the electronic device determines that the in-vehicle device supports voice transmission in a case where the user triggers answering of an incoming call through the electronic device, the electronic device may perform S405.

In some embodiments, if the electronic device determines that the in-vehicle device does not support voice transmission in a case where the user triggers answering of an incoming call through the electronic device, the electronic device may perform S406.

S405, the electronic equipment determines that the voice content is played through the vehicle-mounted equipment.

In the embodiment of the application, if the electronic device determines that the vehicle-mounted device supports voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, the electronic device can determine to play the voice content through the vehicle-mounted device.

In some embodiments, after the electronic device determines that the voice content is played through the in-vehicle device, the electronic device may perform voice transmission with the in-vehicle device through the SCO or the ESCO. After that, the in-vehicle device may play the voice content. The voice content is used to indicate voice data transmitted by the electronic device.

It can be understood that, if the vehicle-mounted device supports voice transmission in the case that the user triggers to answer the incoming call through the electronic device, after the electronic device transmits the voice data to the vehicle-mounted device, the vehicle-mounted device does not disconnect the connection (such as the SCO connection) with the mobile phone, but can directly play the voice content. Therefore, the user can be guaranteed to hear the complete voice content, and the use experience of the user is improved.

Moreover, when a user makes a call through the electronic device, the user may need to hold the electronic device. And when the user calls through the vehicle-mounted equipment, the user does not need to hold the vehicle-mounted equipment. Therefore, the user can talk more conveniently.

S406, the electronic device determines to play the voice content through the electronic device or the first Bluetooth device.

The first Bluetooth device is other Bluetooth devices except the vehicle-mounted device in the plurality of Bluetooth devices which establish Bluetooth connection with the electronic device. The at least one bluetooth device includes an in-vehicle device. The embodiment of the application does not limit other Bluetooth devices except the vehicle-mounted device. For example, the bluetooth device may be a bluetooth speaker, a bluetooth bracelet, or a bluetooth headset.

In some embodiments, the electronic device may establish a bluetooth connection with a plurality of bluetooth devices. The plurality of Bluetooth devices include the in-vehicle device and other Bluetooth devices other than the in-vehicle device. If the electronic device determines that the vehicle-mounted device does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, the electronic device can determine the first Bluetooth device from other Bluetooth devices. Thereafter, the electronic device may determine to play the voice content through the first bluetooth device. Alternatively, the electronic device may determine to play the voice content through the electronic device.

It can be understood that, under the condition that the electronic device is connected with other bluetooth devices except the vehicle-mounted device, if the vehicle-mounted device does not support voice transmission under the condition that a user triggers to answer an incoming call through the electronic device, the electronic device can play voice content through the first bluetooth device. Therefore, the method and the device can ensure that the user can listen to the complete voice content, and the user does not need to hold the electronic equipment for conversation, so that the use experience of the user is improved.

It should be noted that, the first bluetooth device is not limited in this embodiment of the application.

In one possible design, the first bluetooth device may be any one of the other bluetooth devices. Illustratively, suppose that other bluetooth devices include bluetooth speakers, bluetooth bracelets, and bluetooth headsets. The first bluetooth device may be a bluetooth sound; or, the first bluetooth device may be a bluetooth bracelet; alternatively, the first bluetooth device may be a bluetooth headset.

In another possible design, the first bluetooth device may be a bluetooth device that uses the highest frequency among other bluetooth devices. The use frequency of the Bluetooth device is used for indicating the frequency of the electronic device for establishing Bluetooth connection with the Bluetooth device. The use frequency is not limited in the embodiments of the present application. For example, the usage frequency may be the number of times the electronic device establishes a bluetooth connection with a bluetooth device per day. As another example, the usage frequency may be the number of times a bluetooth connection is established between the electronic device and the bluetooth device every week. Specifically, the electronic device may store the usage frequency of the bluetooth device that has established the bluetooth connection with the electronic device, and the relationship between the identifier of the bluetooth device and the usage frequency of the bluetooth device. Wherein, the identification of the Bluetooth device is used for identifying the Bluetooth device. The embodiment of the present application does not limit the identifier of the bluetooth device. For example, the identity of the bluetooth device may be a Media Access Control (MAC) address of the bluetooth device. As another example, the identity of the Bluetooth device may be a device identity (device ID) of the Bluetooth device.

Illustratively, as shown in table 1, the relationship between the identity of the bluetooth device and the frequency of use of the bluetooth device is shown.

TABLE 1

Identification of Bluetooth device	Frequency of use of bluetooth devices
		Identification A	7
Identification B	2
		Identification C	5

That is, the bluetooth device identified as the identifier a has a use frequency of 7, the bluetooth device identified as the identifier B has a use frequency of 2, and the bluetooth device identified as the identifier C has a use frequency of 5.

The electronic device may obtain the identity of other bluetooth devices that establish a bluetooth connection with the electronic device. Then, the electronic device may determine the usage frequency of each of the other bluetooth devices according to the identifiers of the other bluetooth devices and the relationship between the identifiers of the bluetooth devices and the usage frequency of the bluetooth devices. The electronic device may then determine a first bluetooth device based on the frequency of use of each bluetooth device.

Optionally, the use frequency may also be a use time length, a use frequency, and the like, which is not limited in the embodiment of the present application. For the way that the electronic device determines the first bluetooth device according to the use duration or the use times, reference may be made to the foregoing embodiment, which is not described herein again.

It is understood that the first bluetooth device is a bluetooth device that uses the highest frequency among other bluetooth devices. That is, the electronic device may play the voice content through the bluetooth device that uses the highest frequency. Therefore, the incoming call can be answered according to the using habits of the user, and the using experience of the user is improved.

In another possible design, the first bluetooth device may be a bluetooth device that establishes a bluetooth connection with the electronic device before the electronic device establishes a bluetooth connection with the in-vehicle device. For example, it is assumed that the electronic device establishes a bluetooth connection with the bluetooth headset before the electronic device establishes a bluetooth connection with the in-vehicle device. The first bluetooth device may be a bluetooth headset.

In another possible design, the first bluetooth device is a bluetooth device with the highest priority among other bluetooth devices. Specifically, the priority of the plurality of types of devices is stored in the electronic device. The priority of the equipment is used for representing the probability of revealing the voice content when the Bluetooth equipment plays the voice content of the electronic equipment. The higher the priority of the device is, the lower the probability of leaking the voice content when the bluetooth device plays the voice content of the electronic device is. The lower the priority of the device, the greater the probability of revealing the voice content when the bluetooth device plays the voice content of the electronic device.

Illustratively, the plurality of devices includes: a headset-type device, a wearable-type device, and a sound-type device. The priority of the headset type device is higher than the priority of the wearable type device, and the priority of the wearable type device is higher than the priority of the audible type device. The electronic device may obtain a device type for each of the other bluetooth devices. The electronic device may then determine the priority of each of the other bluetooth devices based on the device types of the other bluetooth devices and the priorities of the multiple devices. The electronic device may then determine the first bluetooth device based on the priority of each bluetooth device. For example, if the electronic device establishes a bluetooth connection with a bluetooth headset, a bluetooth watch, or a bluetooth sound, the electronic device may determine that the first bluetooth device is a bluetooth headset. If the electronic device establishes a bluetooth connection with the bluetooth watch and the bluetooth sound, the electronic device may determine that the first bluetooth device is the bluetooth watch.

It is understood that the first bluetooth device is the highest priority bluetooth device among the other bluetooth devices. That is, the electronic device may play the voice content through the bluetooth device that reveals the lowest probability of the voice content. Therefore, the probability of revealing the privacy of the user can be reduced, the safety of voice communication is improved, and the use experience of the user is improved.

In some embodiments, the electronic device establishes a bluetooth connection with the in-vehicle device and does not establish a bluetooth connection with other bluetooth devices. If the electronic equipment determines that the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment, the electronic equipment can determine to play the voice content through the electronic equipment.

It can be understood that if the vehicle-mounted device does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, the electronic device can directly play the voice content. Therefore, the method and the device can ensure that the user can listen to the complete voice content, and improve the use experience of the user.

It should be noted that, in the case that the electronic device and the in-vehicle device establish the bluetooth connection, if the in-vehicle device does not play the voice content, but the electronic device or the bluetooth device plays the voice content, the user may be confused.

In some embodiments, if the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, after the electronic device determines that the voice content is played through the electronic device or the first bluetooth device, the electronic device may display a first prompt message for prompting that the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device.

For example, after the electronic device determines that the voice content is played through the electronic device or the first bluetooth device, the electronic device may display a prompt message 601 as shown in fig. 6, where the prompt message 601 may be a "reminder," and the current vehicle-mounted device does not support the triggering of answering an incoming call on the mobile phone side, and then answers the voice call. Optionally, the prompt message 601 may also be used to indicate the device currently playing the voice content. For example, if the electronic device plays voice content through a Bluetooth headset, the prompting message 601 may also include "note that the device currently engaged in a voice call is a Bluetooth headset! ".

In addition, the display mode of the first prompting message is not limited in the embodiment of the present application. For example, the electronic device may display the first prompting message via a notification message. For another example, the electronic device can display a first prompting message at the notification bar. For another example, the electronic device can display the first prompting message in a pop-up box.

In some embodiments, the first indication may be a first value or a second value. The first numerical value is used for indicating that the vehicle-mounted equipment supports voice transmission under the condition that a user triggers to answer the incoming call through the electronic equipment, and the second numerical value is used for indicating that the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment. For example, if the first indication information is information corresponding to an "AG answer" bit in the BitMap, the "AG answer" bit may be a first value or a second value. The first numerical value and the second numerical value are not limited in the embodiments of the present application. For example, the first value may be 1 and the second value may be 0. For another example, the first value may be 0 and the second value may be 1.

It should be noted that, in the embodiment of the present application, the electronic device may establish a synchronous connection with the in-vehicle device. The synchronous connection is used for transmitting voice data between the electronic equipment and the vehicle-mounted equipment. That is to say, the voice content played by the vehicle-mounted device is the voice content sent by the electronic device to the vehicle-mounted device through the synchronous connection. The embodiment of the present application does not limit the synchronous connection. For example, the synchronous connection may be an SCO connection. Also for example, the synchronization connection may be an ESCO connection. The synchronous connection may also be another connection for synchronizing voice data, for example.

It should be noted that, in the embodiment of the present application, the timing when the electronic device establishes the synchronous connection with the vehicle-mounted device is related to whether the electronic device supports incoming call ringtone synchronization, where the incoming ringtone synchronization is a function of synchronizing an incoming ringtone from the electronic device to the vehicle-mounted device. If the electronic device supports the incoming call ringtone synchronization, the electronic device can establish the synchronous connection with the vehicle-mounted device after the electronic device receives the incoming call. If the electronic equipment does not support incoming call ringtone synchronization, the electronic equipment cannot establish synchronous connection with the vehicle-mounted equipment after receiving an incoming call. Optionally, if the electronic device does not support ring synchronization, the electronic device may establish a synchronous connection with the vehicle-mounted device after the electronic device receives the first operation (that is, the user triggers to answer the call through the electronic device).

In an embodiment of the present application, the electronic device may determine whether the electronic device supports ring tone synchronization according to second indication information, where the second indication information is used to indicate whether the electronic device supports ring tone synchronization. Specifically, the electronic device may obtain the second indication information. For example, the second indication information may be an "in-band ring tone capability" bit in the BitMap format. If the "in-band ring tone capability" bit in the BitMapBitMap format is 0 (i.e., the second indication information is 0), the electronic device determines that the electronic device does not support ring synchronization. If the in-band ring tone bit in the BitMap format is 1 (i.e., the second indication information is 1), the electronic device determines that the electronic device supports ring tone synchronization.

The method of the embodiment of the present application is described below by taking an example in which an electronic device supports ring synchronization. As shown in fig. 7, after S502, the call control method may include S701-S712.

S701, when the electronic equipment receives an incoming call, the electronic equipment sends an incoming call instruction to the vehicle-mounted equipment.

The incoming call instruction is used for indicating the electronic equipment to receive an incoming call.

For example, when the electronic device receives an incoming call, the electronic device may send a first CIEV command (i.e., an incoming call instruction) to the in-vehicle device, where the first CIEV command includes incoming call indication information indicating that the electronic device receives the incoming call. For example, the incoming call indication information may be "callsetup =1".

In the embodiment of the application, when the electronic device receives an incoming call, the electronic device may send an incoming call instruction to the vehicle-mounted device. After that, the in-vehicle device may receive an incoming call instruction from the electronic device. Optionally, after the in-vehicle device receives the incoming call instruction from the electronic device, the in-vehicle device may display an incoming call reminding interface. The vehicle-mounted equipment can receive the incoming call answering operation acted on the incoming call reminding interface by the user so as to trigger the incoming call answering.

In some embodiments, in response to the electronic device receiving an incoming call, the electronic device may determine whether the electronic device supports ring tone synchronization. Optionally, in the process of establishing the bluetooth connection between the electronic device and the vehicle-mounted device, the electronic device may determine whether the electronic device supports ring synchronization. If the electronic device supports ring synchronization, the electronic device may perform S702.

It should be noted that, the way for the electronic device to determine whether the electronic device supports incoming call ringtone synchronization may refer to the method for the electronic device to determine whether the electronic device supports incoming call ringtone synchronization in the foregoing embodiment, which is not described herein again.

S702, the electronic equipment sends a synchronization request message to the vehicle-mounted equipment.

Wherein the synchronization request message is used for requesting to establish a synchronization connection. For example, the synchronization request message may be an LMP _ SCO _ LINK _ REQ message or an LMP _ eSCO _ LINK _ REQ message.

In the embodiment of the application, if the electronic device supports ring synchronization, after receiving an incoming call, the electronic device may send a synchronization request message to the vehicle-mounted device.

And S703, the vehicle-mounted equipment sends a synchronization response message to the electronic equipment.

Wherein the synchronization response message is used to indicate that the synchronization connection has been successfully established. Illustratively, the synchronization response message may be an LMP _ ACCEPT message or an LMP _ ACCEPT _ EXT message.

In the embodiment of the application, the vehicle-mounted device receives the synchronization request message from the electronic device, and can send the synchronization response message to the electronic device. Thereafter, the electronic device may receive a synchronization response message from the in-vehicle device. That is, the synchronous connection has been successfully established between the electronic apparatus and the in-vehicle apparatus.

It should be noted that, in the embodiment of the present application, a process of establishing a synchronous connection between an electronic device and an in-vehicle device is not limited. For example, after the in-vehicle device receives the incoming call instruction, if the electronic device supports ring synchronization, the in-vehicle device may send a synchronization request message to the electronic device. After that, the electronic device may send a synchronization response message to the in-vehicle device.

In some embodiments, after the electronic device receives an incoming call, the electronic device may play an incoming ringtone. After the synchronous connection between the electronic equipment and the vehicle-mounted equipment is successfully established, the electronic equipment can transmit the incoming call ringtone to the vehicle-mounted equipment through the synchronous connection, and instruct the vehicle-mounted equipment to play the incoming ringtone to remind the user of the incoming call. And then, the vehicle-mounted equipment can play the incoming call ringtone. Illustratively, if the synchronous connection is an SCO connection, the electronic device may transmit the ring tone data to the in-vehicle device through the SCO.

S704, the electronic equipment receives a first operation of the user.

In some embodiments, in response to the first operation, the electronic device can send an answering instruction to the vehicle-mounted device, wherein the answering instruction is used for indicating that the incoming call is answered. For example, in response to the first operation, the electronic device may send a second CIEV command (i.e., an answer instruction) to the in-vehicle device, where the CIEV command includes answer indication information indicating that the incoming call has been answered. For example, the hearing indication information may be "call =1".

S705, responding to the first operation, the electronic equipment determines whether the first indication information is a first numerical value.

In some embodiments, if the first indication information is the first value, the electronic device may perform S706-S708. That is, if the in-vehicle device supports voice transmission in a case where the user triggers answering of an incoming call through the electronic device, the electronic device may perform S706-S708.

In some embodiments, if the first indication information is the second numerical value, the electronic device may perform S709 or S710-S712. That is, if the in-vehicle device supports voice transmission in a case where the user triggers to answer the incoming call through the electronic device, the electronic device may perform S709; alternatively, if the in-vehicle device supports voice transmission in a case where the user triggers answering of an incoming call through the electronic device, the electronic device may perform S710-S712.

S706, the electronic equipment determines that the voice content is played through the vehicle-mounted equipment.

In this embodiment of the application, if the first indication information is the first numerical value, the electronic device determines to play the voice content through the vehicle-mounted device. That is, if the in-vehicle device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, the electronic device may determine to play the voice content through the in-vehicle device.

And S707, the electronic equipment sends the voice data to the vehicle-mounted equipment.

In the embodiment of the application, the electronic device determines that the voice content is played through the vehicle-mounted device, and sends the voice data to the vehicle-mounted device through synchronous connection to instruct the vehicle-mounted device to play the voice content corresponding to the voice data. For example, the electronic device may transmit voice data to the in-vehicle device through the SCO.

It can be understood that, since the electronic device supports ring tone synchronization, the electronic device can establish a synchronous connection with the in-vehicle device after receiving an incoming call. Therefore, in S707, when the electronic apparatus transmits the voice data to the in-vehicle apparatus, the electronic apparatus does not need to establish a synchronous connection.

And S708, the vehicle-mounted equipment receives the voice data from the electronic equipment and plays the voice content.

It can be understood that, if the vehicle-mounted device supports voice transmission in a situation where the user triggers to answer the incoming call through the electronic device, after the electronic device transmits the voice data to the vehicle-mounted device, the vehicle-mounted device may directly play the voice content without disconnecting the synchronous connection (such as the SCO connection) with the electronic device. Therefore, the user can be guaranteed to hear the complete voice content, and the use experience of the user is improved.

And S709, the electronic equipment determines to play the voice content through the electronic equipment.

In this embodiment of the application, if the first indication information is the second numerical value, the electronic device determines to play the voice content through the electronic device.

In some embodiments, after the electronic device determines that the voice content is played through the electronic device, the electronic device may not disconnect the synchronous connection with the in-vehicle device. Specifically, if the first indication information is the second numerical value, the electronic device may switch the sound channel to the electronic device, and keep a synchronous connection, such as an SCO connection, between the electronic device and the vehicle-mounted device. That is, the electronic device can maintain a synchronous connection with the in-vehicle device while playing the voice content.

It should be noted that, when the electronic device plays the voice content, synchronous connection is not needed to transmit the voice data. If the electronic device still establishes a synchronous connection with the in-vehicle device, the power consumption of the electronic device may be increased.

In some embodiments, after the electronic device determines that the voice content is played through the electronic device, the electronic device may release the synchronous connection with the in-vehicle device, that is, the electronic device may disconnect the synchronous connection with the in-vehicle device.

As shown in fig. 8, after the electronic device determines to play the voice content through the electronic device, i.e., S709, the control method of the call may further include S801-S802.

S801, the electronic equipment sends a release request message to the vehicle-mounted equipment.

Wherein the release request message is used for indicating the release of the synchronous connection. For example, the release request message may be an LMP _ REMOVE _ SCO _ LINK _ REQ message or an LMP _ REMOVE _ eSCO _ LINK _ REQ message.

S802, the vehicle-mounted equipment sends a release response message to the electronic equipment.

Wherein the release response message is used for indicating that the synchronous connection is successfully released. For example, the release response message may be an LMP _ ACCEPT message or an LMP _ ACCEPT _ EXT message.

In the embodiment of the application, the vehicle-mounted device receives the release request message from the electronic device, and can send a release response message to the electronic device. Thereafter, the electronic device may receive a release response message from the in-vehicle device.

It can be understood that the electronic device releases the synchronous connection with the in-vehicle device, and the power consumption of the electronic device can be reduced. Therefore, the service life of the electronic equipment can be prolonged, and the use experience of a user is improved.

S710, the electronic equipment determines that the voice content is played through the first Bluetooth equipment.

In this embodiment of the application, if the first indication information is the second numerical value and the electronic device establishes bluetooth connection with other bluetooth devices except the vehicle-mounted device, the electronic device determines to play the voice content through the first bluetooth device. Wherein the other Bluetooth devices include the first Bluetooth device.

It should be noted that, the first bluetooth device is not limited in this embodiment of the application. For the description of the first bluetooth device and the manner in which the electronic device determines the first bluetooth device, reference may be made to the description in the foregoing embodiments, which are not repeated herein.

In some embodiments, after the electronic device determines that the first bluetooth device plays the voice content, the electronic device may release the synchronous connection with the in-vehicle device. That is, after the electronic device performs S710, the electronic device may perform S801 and the in-vehicle device may perform S802.

And S711, the electronic equipment sends a synchronization request message to the first Bluetooth equipment.

And S712, the first Bluetooth device sends a synchronous response message to the electronic device.

In this embodiment, the first bluetooth device may send a synchronization response message to the electronic device when receiving the synchronization request message from the electronic device. That is, the electronic device may transmit voice data to the first bluetooth device through the synchronous connection.

It can be understood that, under the condition that the electronic device is connected with other bluetooth devices except the vehicle-mounted device, if the vehicle-mounted device does not support voice transmission under the condition that a user triggers to answer an incoming call through the electronic device, the electronic device can play voice content through the first bluetooth device. Therefore, the method and the device can ensure that the user can answer complete voice content, and the user does not need to hold the electronic equipment for communication, so that the use experience of the user is improved.

In other embodiments, the in-vehicle device may not support ring tone synchronization. If the electronic device does not support incoming call ringtone synchronization, after the electronic device receives an incoming call, the electronic device and the vehicle-mounted device do not execute S702 and S703, that is, the electronic device does not establish synchronous connection with the vehicle-mounted device.

The method of the embodiment of the present application is described below by taking an example that the electronic device does not support incoming ringtone synchronization. As shown in fig. 9, after S502, the control method of the call may include S901-S910.

S901, when the electronic equipment receives an incoming call, the electronic equipment sends an incoming call instruction to the vehicle-mounted equipment.

It should be noted that, for the description of sending the incoming call instruction to the vehicle-mounted device by the electronic device, reference may be made to the description of S701 in the foregoing embodiment, which is not described herein again.

In some embodiments, in response to the electronic device receiving an incoming call, the electronic device may determine whether the electronic device supports ring tone synchronization. Optionally, in the process of establishing the bluetooth connection between the electronic device and the vehicle-mounted device, the electronic device may determine whether the electronic device supports ring synchronization. If the electronic device does not support ring synchronization, the electronic device does not execute S702 and S703 after receiving the incoming call, that is, the electronic device does not establish a synchronous connection with the vehicle-mounted device after receiving the incoming call.

It should be noted that, after the electronic device receives the incoming call, the electronic device may play a ring tone. And after the vehicle-mounted device receives the incoming call instruction from the electronic device, the vehicle-mounted device can play the incoming call ringtone. The incoming call ringtone played by the vehicle-mounted equipment is the incoming call ringtone set by the vehicle-mounted equipment. The incoming call ringtone played by the vehicle-mounted device may be the same as the incoming call ringtone played by the electronic device, or the incoming call ringtone played by the vehicle-mounted device may be different from the incoming call ringtone played by the electronic device.

S902, the electronic equipment receives a first operation of a user.

It should be noted that, for the description of the electronic device receiving the first operation of the user, reference may be made to the description of S704 in the foregoing embodiment, which is not described herein again.

S903, responding to the first operation, the electronic equipment determines whether the first indication information is a first numerical value.

In some embodiments, if the first indication information is the first numerical value, the electronic device may perform S904-S906. That is, if the in-vehicle device supports voice transmission in a case where the user triggers answering of an incoming call through the electronic device, the electronic device may perform S904-S906.

In some embodiments, if the first indication information is the second value, the electronic device may perform S907 or S908-S910. That is, if the in-vehicle device supports voice transmission in a case where the user triggers to answer the incoming call through the electronic device, the electronic device may perform S907; alternatively, if the in-vehicle device supports voice transmission in a case where the user triggers answering of the incoming call through the electronic device, the electronic device may perform S908-S910.

And S904, the electronic equipment determines to play the voice content through the vehicle-mounted equipment.

In this application embodiment, if the first indication information is a first numerical value, the electronic device determines to play the voice content through the vehicle-mounted device. That is, if the in-vehicle device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, the electronic device may determine to play the voice content through the in-vehicle device.

S905, the electronic equipment sends a synchronization request message to the vehicle-mounted equipment.

Wherein the synchronization request message is used for requesting to establish a synchronization connection.

In this embodiment of the application, the electronic device does not support ring synchronization, and after the electronic device receives the first operation of the user, if the first indication information is the first numerical value, the electronic device may send a synchronization request message to the vehicle-mounted device.

It can be understood that, in the case that the electronic device does not support ring synchronization, the electronic device does not establish a synchronous connection with the in-vehicle device when receiving an incoming call. Therefore, after the electronic device determines that the voice content is played through the vehicle-mounted device, a synchronous connection with the vehicle-mounted device needs to be established. In this manner, voice data can be transmitted to the in-vehicle apparatus through the synchronous connection.

And S906, the vehicle-mounted equipment sends a synchronization response message to the electronic equipment.

In the embodiment of the application, the vehicle-mounted device receives the synchronization request message from the electronic device, and can send the synchronization response message to the electronic device. That is, the synchronous connection has been successfully established between the electronic apparatus and the in-vehicle apparatus.

It should be noted that, in the embodiment of the present application, a process of establishing a synchronous connection between an electronic device and an in-vehicle device is not limited. For example, after the in-vehicle device receives the incoming call instruction, if the electronic device supports ring synchronization, the in-vehicle device may send a synchronization request message to the electronic device. After that, the electronic device may transmit a synchronization response message to the in-vehicle device.

In the embodiment of the application, the electronic device receives the synchronization response message from the vehicle-mounted device, and can send the voice data to the vehicle-mounted device through the synchronization connection. For example, the electronic device may transmit voice data to the in-vehicle device through the SCO. The vehicle-mounted equipment receives the voice data from the electronic equipment and can play the voice content.

It can be understood that, if the vehicle-mounted device supports voice transmission under the condition that the user triggers to answer the call through the electronic device, after the electronic device transmits voice data to the vehicle-mounted device, the vehicle-mounted device does not release synchronous connection (such as SCO connection) with the mobile phone, but can directly play voice content. Therefore, the user can be guaranteed to hear the complete voice content, and the use experience of the user is improved.

And S907, the electronic equipment determines to play the voice content through the electronic equipment.

In this embodiment of the application, the electronic device does not support ring synchronization, and if the first indication information is the second value, the electronic device does not execute steps S905 to S906. That is to say, the electronic device does not support ring synchronization, and the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, and the electronic device does not establish synchronous connection with the vehicle-mounted device.

It can be understood that, if the vehicle-mounted device supports voice transmission in a situation where the user triggers to answer the incoming call through the electronic device, after the electronic device transmits voice data to the vehicle-mounted device, the vehicle-mounted device may not release the connection (such as the SCO connection) with the mobile phone, but may directly play the voice content. Therefore, the user can be guaranteed to hear the complete voice content, and the use experience of the user is improved.

In addition, in the embodiment of the application, the electronic equipment cannot establish synchronous connection with the vehicle-mounted equipment. Therefore, the power consumption of the electronic equipment can be reduced, and the service life of the electronic equipment is prolonged.

S908, the electronic device determines to play the voice content through the first Bluetooth device.

In this embodiment of the application, if the first indication information is the second numerical value and the electronic device establishes bluetooth connection with other bluetooth devices except the vehicle-mounted device, the electronic device determines to play the voice content through the first bluetooth device.

S909, the electronic device sends a synchronization request message to the first bluetooth device.

S910, the first Bluetooth device sends a synchronization response message to the electronic device.

It should be noted that, for the descriptions of the processes of S908 to S910, reference may be made to descriptions of S710 to S712 in the foregoing embodiments, and details are not described here.

In some embodiments, if the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, the vehicle-mounted device may refuse to establish the synchronous connection. Specifically, if the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, after the vehicle-mounted device receives the synchronization request message from the electronic device, the vehicle-mounted device may send a response rejection message to the electronic device, where the response rejection message is used to indicate that the synchronization connection is not successfully established. Optionally, the electronic device may determine to play the voice content through the electronic device or the first bluetooth device when receiving the response rejection message from the vehicle-mounted device.

It can be understood that synchronous connection is not established between the vehicle-mounted device and the electronic device, and the electronic device does not perform voice transmission to the vehicle-mounted device, but the electronic device or the first bluetooth device plays voice content. Therefore, the method can avoid the omission of the voice content of the user and improve the use experience of the user.

In other embodiments, the electronic device may determine whether to play the voice content through the in-vehicle device according to the blacklist. The electronic equipment stores a blacklist, the blacklist comprises a plurality of preset vehicle-mounted equipment identifications, and the preset vehicle-mounted equipment identifications are identifications which do not support the vehicle-mounted equipment for voice transmission under the condition that a user triggers to answer an incoming call through the electronic equipment. That is to say, the vehicle-mounted device corresponding to each preset vehicle-mounted device identifier in the preset vehicle-mounted device identifiers in the blacklist does not support voice transmission when the user triggers to answer the incoming call through the electronic device.

It should be noted that the in-vehicle device identifier is used to identify the in-vehicle device. The embodiment of the application does not limit the identification of the vehicle-mounted equipment. For example, the vehicle-mounted device identification may be a MAC address of the vehicle-mounted device. For another example, the vehicle-mounted device identifier may be a device ID of the vehicle-mounted device.

It should be noted that, in the embodiment of the present application, the electronic device may store the blacklist in the manner (a) and the manner (b). The mode (a) is that the electronic device can store a blacklist in advance, and the mode (b) is that the electronic device determines the blacklist according to the time consumed for releasing the synchronous connection between the electronic device and the vehicle-mounted device and stores the blacklist.

In some embodiments, the electronic device may maintain the blacklist by way of (a), i.e., the electronic device may store the blacklist in advance. Specifically, the electronic device may store a plurality of preset vehicle-mounted device identifiers input by a developer when the electronic device leaves a factory. The method for acquiring the preset vehicle-mounted equipment identifier by the developer is not limited in the embodiment of the application. For example, the developer may determine, through a test (e.g., manner (b)), an in-vehicle device that does not support voice transmission in a case where the user triggers to answer an incoming call through the electronic device, and acquire an identifier of the in-vehicle device. For another example, the developer may determine that the vehicle-mounted device that does not support voice transmission when the user triggers to answer the incoming call through the electronic device by acquiring the device information (e.g., the first indication information) of each vehicle-mounted device, and acquire the identifier of the vehicle-mounted device.

In some embodiments, the electronic device may store the blacklist in the manner (b), that is, the electronic device determines the blacklist according to a time period consumed for releasing the synchronous connection between the electronic device and the vehicle-mounted device, and stores the blacklist.

The following describes a method for controlling a call provided by the embodiment of the present application, taking an example that an electronic device supports ring tone synchronization. As shown in fig. 10, the call control method may include S1001-S1011.

S1001, when the electronic equipment receives an incoming call, the electronic equipment sends an incoming call instruction to the vehicle-mounted equipment.

It should be noted that, for the introduction that the electronic device sends the incoming call instruction to the vehicle-mounted device when the electronic device receives an incoming call, reference may be made to the description in S701, which is not described herein again.

In some embodiments, in response to the electronic device receiving an incoming call, the electronic device may determine whether the electronic device supports ring tone synchronization. Optionally, in the process of establishing the bluetooth connection between the electronic device and the vehicle-mounted device, the electronic device may determine whether the electronic device supports ring synchronization. If the electronic device supports ring tone synchronization, the electronic device may perform S1002.

S1002, the electronic equipment sends a synchronization request message to the vehicle-mounted equipment.

It should be noted that, for the description that the electronic device sends the synchronization request message to the vehicle-mounted device, reference may be made to the description in S702, and details are not described here.

S1003, the vehicle-mounted device sends a synchronization response message to the electronic device.

It should be noted that, for the description that the in-vehicle device sends the synchronization response message to the electronic device, reference may be made to the description in S703, which is not described herein again.

S1004, the electronic equipment receives a first operation of a user.

It should be noted that, for the description of the electronic device receiving the first operation of the user, reference may be made to the description in S704, which is not described herein again.

In some embodiments, in response to a first operation of the user, the electronic device may send the voice data to the vehicle-mounted device through the synchronous connection and instruct the vehicle-mounted device to play voice content corresponding to the voice data. If the vehicle-mounted device supports voice transmission under the condition that a user triggers to answer an incoming call through the electronic device, the vehicle-mounted device can play voice content. And, the electronic apparatus does not perform S1005-S1011. If the in-vehicle device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, the electronic device performs S1005-S1011.

S1005, the electronic equipment records the first time.

The first time is the time when the electronic equipment receives the first operation. That is, the first time is used to record the time that triggers answering the incoming call. Illustratively, if the electronic device receives the user's operation at 09.

And S1006, releasing synchronous connection between the electronic equipment and the vehicle-mounted equipment.

In some embodiments, if the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device, the electronic device and the vehicle-mounted device may release the synchronous connection. Specifically, the in-vehicle device receives voice data from the electronic device, and may send a release request message to the electronic device. The electronic device may receive the release request message from the in-vehicle device and transmit a release response message to the in-vehicle device.

And S1007, the electronic device records the second time.

And the second time is the time for releasing the synchronous connection for the first time after the electronic equipment receives the first operation. That is, the second time is a time when the release response message is transmitted for the first time after the electronic device receives the first operation. Exemplarily, if the time for releasing the SCO connection for the first time after the electronic device receives the first operation is 09.

S1008, the electronic device calculates a difference value between the first time and the second time to obtain a first target difference value.

Wherein the first target difference value is used for indicating the time length consumed for releasing the synchronous connection for the first time after receiving the first operation.

Exemplarily, if the first time is 09. That is, it takes 40 milliseconds to release the synchronization connection between the electronic apparatus and the in-vehicle apparatus.

S1009, the electronic device determines whether the first target difference is smaller than a preset time threshold.

It should be noted that, in the embodiment of the present application, the preset time threshold is not limited. For example, the preset time threshold may be 100 milliseconds. For another example, the preset time threshold may be 110 milliseconds. For another example, the preset time threshold may be 90 milliseconds. Typically, the predetermined time threshold may be 100 milliseconds.

In some embodiments, if the first target difference is smaller than the preset time threshold, the electronic device may execute S1010. If the first target difference is greater than the preset time threshold, the electronic device may execute S1011.

S1010, the electronic equipment adds the first equipment identification to a blacklist.

The first device identification is an identification of the vehicle-mounted device which is connected with the electronic device in a Bluetooth mode.

In some embodiments, the electronic device may obtain the first device identification before the electronic device adds the first device identification to the blacklist. The embodiment of the application does not limit the way for the electronic device to obtain the first device identifier. For example, the electronic device may acquire the MAC address of the in-vehicle device during the process of establishing a bluetooth connection with the in-vehicle device.

In this embodiment of the application, if the first target difference is smaller than the preset time threshold, the electronic device may add the first device identifier to a blacklist. For example, if the first target difference is 40 ms and the preset time threshold is 100 ms, the electronic device may add the first device identifier to the blacklist.

It will be appreciated that the first target difference value is less than the predetermined time threshold, indicating that it takes a relatively short period of time to release the synchronisation connection. Therefore, the synchronous connection is released only when the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment, namely the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment.

S1011, the electronic device does not add the first device identification to the blacklist.

In this embodiment of the application, if the first target difference is greater than the preset time threshold, the electronic device does not add the first device identifier to the blacklist. For example, if the first target difference is 200 ms and the predetermined time threshold is 100 ms, the electronic device does not add the first device identifier to the blacklist.

It will be appreciated that the first target difference value is greater than the predetermined time threshold, indicating that it takes a longer time to release the synchronization connection. Therefore, the method can determine that the synchronous connection is not released by voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment.

It should be noted that, only by the time length consumed for releasing the synchronous connection once, it is determined that the releasing of the synchronous connection is caused by that the vehicle-mounted device does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, and may not be accurate.

In some embodiments, to improve accuracy, the electronic device may determine whether to add the first device identification to the blacklist based again on a length of time it takes to release the synchronization connection.

As shown in fig. 11, after S1009, the call control method may further include S1101-S1106.

It should be noted that, in this embodiment of the application, if the first target difference is smaller than the preset time threshold, the electronic device may execute S1101.

S1101, synchronous connection is established between the electronic equipment and the vehicle-mounted equipment.

In the embodiment of the application, the electronic device can establish synchronous connection with the vehicle-mounted device again. Specifically, the electronic device may send a synchronization request message to the in-vehicle device. The vehicle-mounted equipment receives the synchronization request message from the electronic equipment and sends a synchronization response message to the electronic equipment.

In the embodiment of the application, after the synchronous connection is established again between the electronic equipment and the vehicle-mounted equipment, the electronic equipment can send voice data to the vehicle-mounted equipment.

And S1102, the electronic equipment records the third time.

And the third time is the time for establishing the synchronous connection for the second time after the electronic equipment receives the first operation. Optionally, the third time may be a time when the electronic device receives the synchronization response message for the second time after receiving the first operation. Exemplarily, if the time when the electronic device establishes the SCO connection with the vehicle-mounted device for the second time after the electronic device receives the first operation is 09.

S1103, synchronous connection is released between the electronic equipment and the vehicle-mounted equipment.

In the embodiment of the application, if the vehicle-mounted device does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic device, the synchronous connection between the electronic device and the vehicle-mounted device can be released. Specifically, the in-vehicle device receives voice data from the electronic device, and may send a release request message to the electronic device. The electronic device may receive the release request message from the in-vehicle device and transmit a release response message to the in-vehicle device.

And S1104, the electronic equipment records the fourth time.

And the fourth time is the time for releasing the synchronous connection for the second time after the electronic equipment receives the first operation. Optionally, the fourth time may be a time when the electronic device transmits the release response message for the second time after receiving the first operation.

S1105, the electronic device calculates a difference between the third time and the fourth time to obtain a second target difference.

And the second target difference value is used for indicating the time length consumed for releasing the synchronous connection for the second time after receiving the first operation.

S1106, the electronic device determines whether the second target difference is smaller than a preset time threshold.

In some embodiments, if the second target difference is smaller than the preset time threshold, the electronic device may execute S1010. That is to say, if the duration consumed by releasing the synchronous connection twice between the electronic device and the vehicle-mounted device is less than the preset time threshold, the electronic device may add the first device identifier to the blacklist.

If the second target difference is greater than the preset time threshold, the electronic device may perform S1011. That is to say, if the duration consumed by the second time of releasing the synchronous connection between the electronic device and the vehicle-mounted device is greater than the preset time threshold, the electronic device does not add the first device identifier to the blacklist.

It can be understood that the electronic device can more accurately determine whether the vehicle-mounted device supports voice transmission under the condition that the user triggers to answer the call through the electronic device by releasing the time consumed by the synchronous connection for many times, so that the accuracy of the blacklist is improved.

The following describes a method for controlling a call provided by the embodiment of the present application, by taking an example that an electronic device does not support incoming ringtone synchronization. As shown in fig. 12, the call control method may include S1201-S1216.

And S1201, when the electronic equipment receives the incoming call, the electronic equipment sends an incoming call instruction to the vehicle-mounted equipment.

In some embodiments, in response to the electronic device receiving an incoming call, the electronic device may determine whether the electronic device supports ring tone synchronization. Optionally, in the process of establishing the bluetooth connection between the electronic device and the vehicle-mounted device, the electronic device may determine whether the electronic device supports ring synchronization. If the electronic device does not support ring synchronization, S1002 and S1003 are not executed.

S1202, the electronic equipment receives a first operation of a user.

S1203, the electronic equipment records the first time.

It should be noted that, for the description of the electronic device recording the first time, reference may be made to the description in S1005, and details are not described here.

And S1204, establishing synchronous connection between the electronic equipment and the vehicle-mounted equipment.

It should be noted that, for the description of establishing the synchronous connection between the electronic device and the vehicle-mounted device, reference may be made to the description in S702 and S703, which is not described herein again.

In the embodiment of the application, in response to the first operation, the electronic device may establish a synchronous connection with the in-vehicle device. Wherein, the time when the electronic device receives the first operation of the user is the same or nearly the same as the time when the synchronous connection is established between the electronic device and the vehicle-mounted device (i.e. the time difference is small). That is, the first time may also be a time when a synchronous connection is established between the electronic apparatus and the in-vehicle apparatus.

In some embodiments, a synchronous connection is established between the electronic device and the vehicle-mounted device, and the electronic device can transmit the synchronous connection to the vehicle-mounted device

And S1205, synchronous connection is released between the electronic equipment and the vehicle-mounted equipment.

And S1206, the electronic equipment records the second time.

It should be noted that, for the description of the electronic device recording the second time, reference may be made to the description in S1007, and details are not described here.

S1207, the electronic device calculates a difference between the first time and the second time to obtain a first target difference.

It should be noted that, for the introduction that the electronic device calculates the difference between the first time and the second time to obtain the first target difference, reference may be made to the description in S1008, which is not described herein again.

S1208, the electronic device determines whether the first target difference is smaller than a preset time threshold.

It should be noted that, for the description that the electronic device determines whether the first target difference is smaller than the preset time threshold, reference may be made to the description in S1009, which is not described herein again.

In some embodiments, if the first target difference is smaller than the preset time threshold, the electronic device may execute S1215. If the first target difference is greater than the preset time threshold, the electronic device may execute S1216.

In other embodiments, if the first target difference is smaller than the predetermined time threshold, the electronic device may perform S1209-S1215. If the first target difference is greater than the preset time threshold, the electronic device may execute S1216.

S1209, synchronous connection is established between the electronic equipment and the vehicle-mounted equipment.

It should be noted that, for the description of establishing the synchronous connection between the electronic device and the vehicle-mounted device, reference may be made to the description in S1101, and details are not described here.

S1210, the electronic equipment records the third time.

It should be noted that, for the description of the electronic device recording the third time, reference may be made to the description in S1102, which is not described herein again.

And S1211, releasing synchronous connection between the electronic equipment and the vehicle-mounted equipment.

It should be noted that, for the description of releasing the synchronous connection between the electronic device and the vehicle-mounted device, reference may be made to the description in S1103, and details are not described here.

And S1212, the electronic equipment records the fourth time.

It should be noted that, for the description of the electronic device recording the fourth time, reference may be made to the description in S1104, and details are not described here.

S1213, the electronic device calculates a difference between the third time and the fourth time to obtain a second target difference.

It should be noted that, for the electronic device calculating the difference between the third time and the fourth time to obtain the description of the second target difference, reference may be made to the description in S1105, which is not repeated herein.

S1214, the electronic equipment determines whether the second target difference value is smaller than a preset time threshold value.

In some embodiments, if the second target difference is smaller than the preset time threshold, the electronic device may execute S1215. That is, if the time taken for releasing the synchronization connection twice between the electronic device and the in-vehicle device is less than the preset time threshold, the electronic device may execute S1215.

If the second target difference is greater than the preset time threshold, the electronic device may execute S1216. That is, if the time duration taken for releasing the synchronous connection between the electronic device and the vehicle-mounted device for the second time is greater than the preset time threshold, the electronic device may execute S1216.

S1215, the electronic device adds the first device identification to the blacklist.

It should be noted that, for the description that the electronic device adds the first device identifier to the blacklist, reference may be made to the description in S1215, which is not described herein again.

It will be appreciated that the first target difference (or the first target difference and the second target difference) is less than the predetermined time threshold, indicating that it takes a relatively short period of time to release the synchronization connection. Therefore, the synchronous connection is released only when the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment, namely the vehicle-mounted equipment does not support voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment.

S1216, the electronic device does not add the first device identification to the blacklist.

It will be appreciated that the first target difference (or the first target difference and the second target difference) is greater than the predetermined time threshold, indicating that it takes a longer time to release the synchronization connection. Therefore, the method can determine that the synchronous connection is not released by voice transmission under the condition that the user triggers to answer the incoming call through the electronic equipment.

The method for controlling a phone call provided in the embodiment of the present application is described below by taking an example in which an electronic device supporting synchronization of incoming call ringtones determines whether to play a voice content through a vehicle-mounted device according to a blacklist. As shown in fig. 13, after S1005, the control method of the call may include S1301-S1302.

S1301, the electronic equipment determines whether the first equipment identification is in a blacklist.

For example, the electronic device may determine whether the same identifier as the first device identifier exists in a plurality of preset in-vehicle device identifiers.

In some embodiments, if the electronic device determines that the first device identifier is in the blacklist, the electronic device may perform S1302. That is, if the same identifier as the first device identifier exists in the plurality of preset in-vehicle device identifiers, the electronic device may execute S1302. If the electronic device determines that the first device identification is not in the blacklist, the electronic device may perform S1006-S1011 and S1302. That is, if the same identifier as the first device identifier does not exist in the plurality of preset in-vehicle device identifiers, the electronic device may execute S1006-S1011 and S1302.

In some embodiments, if the electronic device determines that the first device identifier is not in the blacklist and the synchronous connection between the electronic device and the vehicle-mounted device is not released, the electronic device may send the voice data to the vehicle-mounted device through the synchronous connection. The vehicle-mounted equipment can play voice content. That is, if the electronic device determines that the first device identifier is not in the blacklist and the synchronous connection between the electronic device and the in-vehicle device is not released, the electronic device does not execute S1006-S1011 and S1302.

S1302, the electronic device determines to play the voice content through the electronic device.

In the embodiment of the application, if the electronic device determines that the first device identifier is in the blacklist, it can be determined that the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device. The electronic device can determine to play the voice content through the electronic device. That is, if the electronic device determines that the first device identifier is in the blacklist, the electronic device may play the voice content.

It can be understood that if the electronic device determines that the first device identifier is in the blacklist, the electronic device may directly play the voice content. Therefore, the situation that the voice content is not played by the vehicle-mounted equipment and the electronic equipment can be avoided. Therefore, the method and the device can ensure that the user can listen to the complete voice content, and improve the use experience of the user.

The following describes a control method of a call provided by the embodiment of the present application, by taking an example that an electronic device that does not support incoming call ringtone synchronization determines whether to play a voice content through a vehicle-mounted device according to a blacklist. As shown in fig. 14, after S1203, the control method of the call may include S1401-S1402.

S1401, the electronic device determines whether the first device identifier is in a blacklist.

In some embodiments, if the electronic device determines that the first device identification is in the blacklist, the electronic device may perform S1402. That is, if the same identifier as the first device identifier exists in the plurality of preset in-vehicle device identifiers, the electronic device may execute S1402. If the electronic device determines that the first device identification is not in the blacklist, the electronic device may perform S1204-S1216, followed by S1402. That is, if there is no identifier identical to the first device identifier in the plurality of preset in-vehicle device identifiers, the electronic device may execute S1204-S1216, and then execute S1402.

S1402, the electronic equipment plays the voice content.

In the embodiment of the application, if the electronic device determines that the first device identifier is in the blacklist, it can be determined that the vehicle-mounted device does not support voice transmission when the user triggers to answer the incoming call through the electronic device. The electronic device can determine to play the voice content through the electronic device.

In some embodiments, the electronic device may release the synchronization connection if the electronic device determines that the first device identification is in the blacklist. Specifically, for the description of releasing the synchronous connection of the electronic device, reference may be made to the description of releasing the synchronous connection between the electronic device and the vehicle-mounted device in the foregoing embodiment, which is not described herein again.

In other embodiments, the electronic device may not release the synchronization connection if the electronic device determines that the first device identification is on the blacklist.

In some embodiments, if the electronic device determines that the first device identifier is in the blacklist, the electronic device may play the voice content through the first bluetooth device. Specifically, for the method for playing the voice content by the electronic device through the first bluetooth device, reference may be made to the description of the electronic device playing the voice content through the first bluetooth device in the foregoing embodiment, which is not described herein again.

It can be understood that if the electronic device determines that the first device identifier is in the blacklist, the electronic device may play the voice content through the first bluetooth device. Therefore, the method and the device can ensure that the user can answer complete voice content, and the user does not need to hold the electronic equipment for communication, so that the use experience of the user is improved.

It should be noted that the in-vehicle device may continuously improve the supported functional characteristics, so that the in-vehicle device supports voice transmission when the user triggers to answer the incoming call through the electronic device. Therefore, if it may not be accurately determined whether the vehicle-mounted device supports voice transmission under the condition that the user triggers to answer the call through the electronic device only according to the blacklist, it may not be determined whether to play the voice content through the vehicle-mounted device.

In some embodiments, the electronic device may update the blacklist. And then, the electronic equipment can determine whether to play the voice content through the vehicle-mounted equipment according to the updated blacklist. The embodiment of the present application does not limit the manner in which the electronic device updates the blacklist.

In a possible implementation manner, the electronic device may delete all the preset vehicle-mounted device identifiers in the blacklist every time the electronic device is powered on, or every preset period (for example, one day, three days, or ten days). Thereafter, when the electronic device receives an incoming call, S1001 to S1302 (i.e., the flow shown in fig. 13) or S1201 to S1402 (i.e., the flow shown in fig. 14) described above is re-executed.

In another possible implementation manner, if the electronic device determines that the first device identifier is in the blacklist, the electronic device may not release the synchronous connection. If the synchronous connection between the electronic equipment and the vehicle-mounted equipment is not released within the preset time after the electronic equipment receives the first operation, the electronic equipment can delete the first equipment identifier from the blacklist. That is to say, if the time length for the electronic device to maintain the synchronous connection with the vehicle-mounted device after receiving the first operation is longer than the preset time length, the electronic device may delete the first device identifier from the blacklist.

Optionally, after the electronic device deletes the first device identifier from the blacklist, the electronic device may determine to play the voice content through the in-vehicle device.

It can be understood that the vehicle-mounted device supports voice transmission under the condition that a user triggers to answer an incoming call through the electronic device, and the electronic device can play voice contents through the vehicle-mounted device. Therefore, the method and the device can ensure that the user can answer complete voice content, and the user does not need to hold the electronic equipment for communication, so that the use experience of the user is improved.

In some embodiments, the electronic device can upload the blacklist to a server, which can receive and store the blacklist. The server may then synchronize the list with other electronic devices. Also, the electronic device may receive a blacklist from the server. The embodiment of the present application does not limit the server. For example, the server may be a cloud server. As another example, the server may be a physical server.

It can be understood that the blacklist can be obtained by other electronic devices by synchronizing the blacklist with the server. Therefore, the process that other electronic equipment executes the blacklist adding process can be reduced, and the efficiency of the electronic equipment is improved.

In some embodiments, the electronic device may also store a white list that stores the identification of the in-vehicle device that supports voice transmission in the event that the user triggers answering of an incoming call through the electronic device. The electronic equipment can determine whether to play the voice content through the vehicle-mounted equipment according to the white list. If the first device identifier exists in the white list, the electronic device may determine to play the voice content through the vehicle-mounted device. If the first device identifier does not exist in the white list, the electronic device may determine to play the voice content through the electronic device.

It should be noted that, if the vehicle-mounted device supports voice transmission when the user triggers to answer the incoming call through the electronic device, the electronic device determines that the voice content is played through the vehicle-mounted device, the voice content may be leaked, and the user experience is reduced.

In some embodiments, if the vehicle-mounted device supports voice transmission in a case where a user triggers to answer an incoming call through the electronic device, the vehicle-mounted device may determine whether to play a voice content through the vehicle-mounted device according to whether a target vehicle loaded with the vehicle-mounted device is in a driving state. Specifically, the in-vehicle apparatus may detect whether the target vehicle is traveling. If the target vehicle is not running, the vehicle-mounted device may release the synchronous connection, or the vehicle-mounted device may refuse to establish the synchronous connection. Thereafter, the electronic device can play the voice content. That is, if the target vehicle is in a stationary state (i.e., the target vehicle is not running), even if the in-vehicle device supports voice transmission in a situation where the user triggers to answer the incoming call through the electronic device, the electronic device still plays the voice content.

It should be noted that, the method for detecting whether the target vehicle is running by the vehicle-mounted device may refer to a method for detecting whether the vehicle is running in the conventional technology, which is not described herein again. Moreover, for the description that the vehicle-mounted device releases the synchronous connection and the vehicle-mounted device refuses to establish the synchronous connection, reference may be made to the description in the foregoing embodiment, which is not described herein again.

It can be understood that if the target vehicle is not in motion, the user answering the call through the electronic device will not affect the user driving the target vehicle. Moreover, the electronic equipment plays the voice content without playing the voice content. Therefore, the privacy of the call can be improved, and the use experience of the user is improved.

If the target vehicle is running, the vehicle-mounted equipment can play the voice content. That is, if the target vehicle is in a driving state (i.e., the target vehicle is driving), and the in-vehicle device supports voice transmission in a case where the user triggers to answer the incoming call through the electronic device, the in-vehicle device may play the voice content.

It can be understood that if the target vehicle is running, the vehicle-mounted device plays the voice content. Therefore, the method and the device can ensure that the user can answer complete voice content, and the user does not need to hold the electronic equipment for communication, so that the use experience of the user is improved.

In some embodiments, the electronic device may set whether to play the voice content through the in-vehicle device. The embodiment of the application does not limit the way of setting whether the electronic equipment plays the voice content through the vehicle-mounted equipment. For example, the electronic device may set whether to play the voice content through the in-vehicle device through the setting option. For example, as shown in fig. 15, the electronic device may display a settings interface 1501, the settings interface 1501 including an "in-vehicle device talk" option 1502, the "in-vehicle device talk" option 1502 being used to control whether voice content is played through the in-vehicle device. For example, the electronic device may set whether to play the voice content through the in-vehicle device when receiving the incoming call. For example, the electronic device is provided with a preset key, and the preset key is used for triggering answering of an incoming call through the vehicle-mounted device. That is, in response to a first operation applied to the preset key, the electronic device may determine to play the voice content through the in-vehicle device. For another example, if the first operation is a preset operation (e.g., a long-press operation or a double-click operation), the electronic device may determine to play the voice content through the in-vehicle device.

It can be understood that the electronic device sets whether to play the voice content through the vehicle-mounted device, and the voice content can be guaranteed to be played in a mode set by a user. Therefore, the use experience of the user can be improved.
