[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0043] Figure 1 is a structural diagram of a call system provided by an embodiment of the present application. Figure 1 The system may include: an electronic device 10, a mobile terminal 20 and a Bluetooth peripheral device 30. The electronic device 10 may establish Bluetooth protocol connections with the mobile terminal 20 and the Bluetooth peripheral device 30 respectively.

[0044] Optionally, the electronic device 10 may be a smart phone, a tablet computer, or a vehicle-mounted terminal, etc., the mobile terminal 20 may be a smart phone or a tablet computer, etc., and the operating system of the mobile terminal may be an Android operating system. The Bluetooth peripheral 30 may be a Bluetooth headset, a Bluetooth speaker, or a wearable device, etc. For example, Figure 1 As shown, the electronic device 10 may be a tablet computer, the mobile terminal 20 may be a smart phone, and the Bluetooth peripheral 30 may be a Bluetooth headset.

[0045] In the embodiment of the present application, after receiving the first call request, the mobile terminal 20 can send the first call request to the electronic device 10, and the electronic device 10 can forward the first call request to the Bluetooth peripheral. In addition, after receiving the first answering instruction sent by the Bluetooth peripheral, the electronic device 10 can forward the audio data of the first call sent by the mobile terminal 20 to the Bluetooth peripheral, and can forward the audio data of the first call sent by the Bluetooth peripheral to the mobile terminal. That is, the electronic device 10 can play a bridging role between the mobile terminal 20 and the Bluetooth peripheral 30, so that the mobile terminal 20 and the Bluetooth peripheral 30 can exchange audio data.

[0046] The present application embodiment provides a calling method, which can be applied to electronic devices, such as Figure 1 The electronic device 10 is shown. Figure 2 , the method may include:

[0047] Step 101: forward a first call request sent by a mobile terminal to a Bluetooth peripheral device.

[0048] The mobile terminal and the Bluetooth peripheral device may both establish a Bluetooth protocol connection with the electronic device, and the first call request is a call request received by the mobile terminal.

[0049] Step 102: In response to the first answering instruction sent by the Bluetooth peripheral device, instruct the mobile terminal to connect the first call.

[0050] After forwarding the first call request of the mobile terminal to the Bluetooth peripheral device, the electronic device may receive a first answering instruction sent by the Bluetooth peripheral device, and in response to the first answering instruction, instruct the mobile terminal to connect the first call.

[0051] Step 103: forward the audio data of the first call sent by the mobile terminal to the Bluetooth peripheral device, and forward the audio data of the first call sent by the Bluetooth peripheral device to the mobile terminal.

[0052] After instructing the mobile terminal to connect the first call, the electronic device can forward the audio data of the first call sent by the mobile terminal to the Bluetooth peripheral device, and can forward the audio data of the first call sent by the Bluetooth peripheral device to the electronic device.

[0053] In summary, the embodiment of the present application provides a call method, whereby the electronic device can forward the first call request sent by the mobile terminal to the Bluetooth peripheral device, and after receiving the first answering instruction sent by the Bluetooth peripheral device, the audio data of the first call can be exchanged between the mobile terminal and the Bluetooth peripheral device. Since the electronic device can forward the audio data of the mobile terminal to the Bluetooth peripheral device, the user can receive the incoming call of the mobile terminal through the Bluetooth peripheral device and make a call, thereby avoiding missing the incoming call of the mobile terminal.

[0054] The present application embodiment provides a communication method, which can be applied to a communication system, such as Figure 1 Intercom system shown. Figure 3 , the method may include:

[0055] Step 201: The electronic device displays a QR code.

[0056] In an embodiment of the present application, a remote control client may be installed in the electronic device. When the electronic device establishes a Bluetooth connection with a mobile terminal for the first time, if the remote control client is not installed in the mobile terminal, the user can control the remote client installed in the electronic device to display a QR code for the mobile terminal to obtain the remote control client. The mobile terminal can scan the QR code to download the remote control client, and then establish a Bluetooth protocol connection with the electronic device through the remote control client. The remote control client installed on the electronic device may be the same as or different from the remote control client installed on the mobile terminal. The Bluetooth protocol used for the Bluetooth protocol connection is the hands-free profile (HFP) protocol or the advanced audio distribution profile (A2DP) protocol.

[0057] Optionally, after scanning the QR code, the mobile terminal can obtain the download address of the remote client, which is the Internet Protocol (IP) address of the background server of the remote client. After that, the mobile terminal can access the background server based on the download address, and send a request to the background server to obtain the installation package of the remote control client. The background server can respond to the acquisition request and send the installation package to the mobile terminal. Accordingly, the mobile terminal can receive and parse the installation package and install the remote control client.

[0058] It should be noted that the electronic device can first establish a Generic Attribute Profile (GATT) connection with the mobile terminal, that is, a connection established based on the GATT protocol. Afterwards, the mobile terminal can send an HFP protocol connection request or an A2DP protocol connection request to the electronic device through the GATT connection. That is, the electronic device and the mobile terminal can establish an HFP protocol connection or an A2DP protocol connection based on the GATT connection.

[0059] Step 202: The mobile terminal sends a connection request to the electronic device through the remote client.

[0060] After acquiring the remote control client, the mobile terminal may run the remote control client and send a connection request to the electronic device through the remote control client.

[0061] Optionally, the mobile terminal can also send a wireless fidelity connection request to the electronic device through the remote control client and the GATT connection. After receiving the wireless fidelity connection request, the electronic device can respond to the wireless fidelity connection request, establish a wireless fidelity connection with the mobile terminal, and interact with the mobile terminal based on the wireless fidelity connection interface data. For example, the mobile terminal can project its screen to the electronic device through the wireless fidelity connection. Accordingly, the electronic device can display the current interface of the mobile terminal on its display interface and can control the mobile terminal, that is, the electronic device can remotely control the mobile terminal.

[0062] For example, assuming that the current display interface of the mobile terminal 20 is a call interface, and the mobile terminal 20 projects the call interface to an electronic device, then see Figure 4 , the electronic device 10 can display the call interface on its display interface. Figure 4 As shown, the call interface may include: an intercept call control 01 , a make call control 02 , and a fold keyboard control 03 .

[0063] And, from Figure 4 It can be seen that if the electronic device 10 responds to the user's touch operation on the keys "1, 2 and 3" in the keyboard of the call interface and displays the numbers corresponding to the keys (i.e. 1, 2 and 3), the mobile terminal 20 can also respond to the touch operation and display the same numbers.

[0064] It should be noted that, during the process of the electronic device controlling the mobile terminal, the mobile terminal may also respond to the user's operation and send an interrupt control instruction to the electronic device to interrupt the controlled state. In response to the interrupt control instruction, the electronic device may display its own interface instead of the current interface of the mobile terminal, and end the interface control of the mobile terminal.

[0065] Step 203: The electronic device establishes a Bluetooth protocol connection with the mobile terminal.

[0066] After receiving the connection request sent by the mobile terminal, the electronic device can establish a Bluetooth protocol connection with the mobile terminal.

[0067] Optionally, after receiving the connection request sent by the mobile terminal, the electronic device may send a connection establishment response to the mobile terminal, thereby establishing a Bluetooth protocol connection with the mobile terminal.

[0068] For example, assuming that the Bluetooth protocol is the HFP protocol, after receiving a connection request sent by the mobile terminal, the electronic device can call the Bluetooth headset client (BluetoothHeadsetClient) object and load the connection (connect) function and the audio connection (connectAudio) function in the object to establish an HFP protocol connection with the mobile terminal.

[0069] In the embodiment of the present application, the electronic device may also establish a Bluetooth protocol connection with a Bluetooth peripheral device during the process of establishing a Bluetooth protocol connection with a mobile terminal. That is, the electronic device may establish a Bluetooth protocol connection with the mobile terminal and the Bluetooth peripheral device respectively. Optionally, the Bluetooth peripheral device may be a vehicle-mounted device, such as a vehicle-mounted speaker.

[0070] The process of establishing a Bluetooth protocol connection between the electronic device and the Bluetooth peripheral device may include: the electronic device turns on Bluetooth and searches for a pairing device, and when the Bluetooth peripheral device is found, sends a pairing request to the Bluetooth peripheral device. After receiving the pairing request, the Bluetooth peripheral device may respond to the pairing request and establish a Bluetooth protocol connection with the electronic device.

[0071] In the embodiment of the present application, since the electronic device can control the mobile terminal and can be controlled by the Bluetooth peripheral, the electronic device can support the audio gateway (AG) role and the hands free (HF) role, that is, the electronic device can act as both a client and a server. The mobile terminal can support the AG role, and the Bluetooth peripheral can support the HF role. In addition, the electronic device can establish a Bluetooth protocol connection with the mobile terminal in the HF role, and establish a Bluetooth protocol connection with the Bluetooth peripheral in the AG role.

[0072] Optionally, developers can set device attributes by configuring the device's HFP profile according to the role that the device needs to support, so that the device supports the role. The HFP profile may include the profile_supported_hs_hfp attribute and the profile_supported_hfpclient attribute. The device attributes may be configured before the device leaves the factory.

[0073] For example, a mobile terminal needs to support the AG role, so before it leaves the factory, the developer can set the profile_supported_hs_hfp attribute in the hfpprofile of the mobile terminal to the enabled state, and the profile_supported_hfpclient attribute to the disabled state, so that the mobile terminal supports the AG role. An electronic device needs to support both the AG role and the HF role, so before it leaves the factory, the developer can set both the profile_supported_hs_hfp attribute and the profile_supported_hfpclient attribute in the hfp profile of the electronic device to the enabled state, so that the electronic device supports both the AG role and the HF role. A Bluetooth peripheral needs to support the HF role, so before it leaves the factory, the developer can set the profile_supported_hfpclient attribute in the hfp profile of the Bluetooth peripheral to the enabled state, and the profile_supported_hs_hfp attribute to the disabled state, so that the Bluetooth peripheral supports the HF role.

[0074] Step 204: The mobile terminal sends a first call request to the electronic device.

[0075] In the embodiment of the present application, the mobile terminal can make or receive a call. When the mobile terminal receives the first call request, the mobile terminal can send the first call request to the electronic device based on the Bluetooth protocol connection between the mobile terminal and the electronic device.

[0076] The first call request may be sent by the call server to the mobile terminal, and the first call request may carry an incoming call number.

[0077] Figure 5 Schematic diagram of a protocol stack of the HFP protocol provided in an embodiment of the present application. Figure 5As shown, the protocol stack of the HFP protocol is a five-layer architecture, which is composed of the following from top to bottom: application layer 01, hands-free control layer 02, transport layer 03, link layer 04 and baseband layer 04. Among them, the transmission protocol based on the transport layer 03 may include the radio frequency communication (RFCOMM) protocol and the service discovery protocol (SDP). The transmission protocol based on the link layer 04 may include the link management protocol (LMP) and the logical link control and adaptation protocol (L2CAP). In addition, the application layer supporting the AG role can be used for audio serial port emulation, and the application layer supporting the HF role can be used for audio driver.

[0078] The process of the mobile terminal sending the first call request to the electronic device may include: the mobile terminal transmits the first call request to the baseband layer 05 through the application layer 01, the hands-free control layer 02, the transport layer 03, and the link layer 04 in sequence. Then, the first call request may be transmitted from the baseband layer 05 of the mobile terminal to the baseband layer 05 of the electronic device. Thereafter, the first call request may be transmitted from the baseband layer 05 to the application layer 01 through the link layer 04, the transport layer 03, and the hands-free control layer 02 in sequence.

[0079] Step 205: The electronic device forwards the first call request sent by the mobile terminal to the Bluetooth peripheral device.

[0080] After receiving the call request, the electronic device may forward the first call request to the Bluetooth peripheral device based on the Bluetooth protocol connection between the electronic device and the Bluetooth peripheral device.

[0081] Optionally, after receiving the first call request sent by the mobile terminal, that is, an incoming call event, the electronic device can also call the audio simulation function in the Bluetooth protocol to simulate the actual incoming call of the electronic device and display the incoming call interface. Since the electronic device has established a Bluetooth protocol connection with the Bluetooth peripheral in the AG role, the Bluetooth peripheral can play the incoming ringtone of the actual incoming call, thereby realizing that the electronic device forwards the first call request sent by the mobile terminal to the Bluetooth peripheral.

[0082] For example, assuming that the electronic device is connected to the mobile terminal via the HFP protocol, after receiving the incoming call event, the electronic device can call the audio simulation function included in the audio manager setting mode (AudioManager.setMode) object in the HFP protocol, such as the incoming call mode setting (AudioManager.Mode_In_Call) function, to simulate the actual incoming call of the electronic device and display Figure 6 The incoming call interface shown. Figure 6 It can be seen that the incoming call interface may include: incoming call number 12335, call hang-up control 04 and call answering control 05.

[0083] Step 206: The Bluetooth peripheral device sends a first answering instruction to the electronic device.

[0084] After receiving the first call request, the Bluetooth peripheral device may play the incoming call ringtone. Afterwards, the Bluetooth peripheral device may generate a first answering instruction in response to the user's answering control operation, and send the first answering instruction to the electronic device. The answering control operation may be a voice control operation or a touch control operation. The touch control operation may be a touch control operation of the user on the answering control on the Bluetooth peripheral device.

[0085] Optionally, after receiving the first call request, the Bluetooth peripheral device may further identify the incoming call number carried in the first call request, determine an audio signal corresponding to the incoming call number, and play the audio signal.

[0086] Step 207: The electronic device instructs the mobile terminal to connect the first call in response to the first answering instruction sent by the Bluetooth peripheral device.

[0087] After receiving the first answering instruction sent by the Bluetooth peripheral device, the electronic device can respond to the first answering instruction and instruct the mobile terminal to connect the first call.

[0088] Optionally, the electronic device can simulate the event of answering the call in response to the first answering instruction, and connect the first call. Since the Bluetooth role of the mobile terminal is currently the AG role, and the Bluetooth role of the electronic device is the HF role, that is, the electronic device can control the mobile terminal, so the electronic device connects the first call, which can control the mobile terminal to connect the first call.

[0089] Step 208: The electronic device forwards the audio data of the first call sent by the mobile terminal to the Bluetooth peripheral device, and forwards the audio data of the first call sent by the Bluetooth peripheral device to the mobile terminal.

[0090] After instructing the mobile terminal to connect the first call, the electronic device can forward the audio data of the first call sent by the mobile terminal to the Bluetooth peripheral device, and can forward the audio data of the first call sent by the Bluetooth peripheral device to the electronic device, thereby realizing the call. At this time, for the user, the receiver or speaker of the Bluetooth peripheral device is the output device of the audio data, and the microphone of the Bluetooth peripheral device is the input device of the audio data.

[0091] In an embodiment of the present application, the electronic device may include a first audio channel and a second audio channel. The electronic device may exchange audio data with the mobile terminal through the first audio channel, and may exchange audio data with the Bluetooth peripheral through the second audio channel.

[0092] Before the electronic device forwards the audio data sent by the mobile terminal to the Bluetooth peripheral device, the first audio path and the second audio path can be connected first. Afterwards, the electronic device can send the audio data of the first call sent by the mobile terminal to the Bluetooth peripheral device through the connected first audio path and second audio path. In addition, the electronic device can send the audio data of the first call sent by the Bluetooth peripheral device to the mobile terminal through the connected first audio path and second audio path, thereby realizing the interaction of audio data between the mobile terminal and the Bluetooth peripheral device.

[0093] Optionally, the electronic device may further include an audio switching circuit, and the electronic device may send a connection instruction to the audio switching circuit before forwarding the audio data sent by the mobile terminal to the Bluetooth peripheral device. The audio switching circuit may connect the first audio path and the second audio path in response to the connection instruction.

[0094] By executing the above steps 204 to 208, the electronic device can realize the interaction of audio data between the mobile terminal and the Bluetooth peripheral device.

[0095] In the embodiment of the present application, during the interaction of audio data between the mobile terminal and the Bluetooth peripheral device, the electronic device may further perform the following steps:

[0096] Step 209: During the process of exchanging audio data between the mobile terminal and the Bluetooth peripheral device, the electronic device detects whether a second call request is received.

[0097] The second call request may be sent by the call server to the electronic device, and the second call request may carry the incoming call number.

[0098] In the embodiment of the present application, during the process of exchanging audio data between the mobile terminal and the Bluetooth peripheral, the electronic device can detect whether the second call request is received, that is, the electronic device and the mobile terminal both receive the call request sent by the call server. If the electronic device receives the second call request, step 210 is executed. If the electronic device does not receive the second call request, the above step 208 is continued.

[0099] Step 210: The electronic device sends a second call request to the Bluetooth peripheral device.

[0100] After receiving the second call request, the electronic device may send the second call request to the Bluetooth peripheral device based on the Bluetooth protocol connection established between the electronic device and the Bluetooth peripheral device. Correspondingly, the Bluetooth peripheral device may receive the second call request.

[0101] Step 211: The Bluetooth peripheral device sends a second answering instruction to the electronic device.

[0102] After receiving the second call request, the Bluetooth peripheral device may no longer play the audio data collected by the mobile terminal and sent by the electronic device, but first play the incoming call ringtone. Afterwards, if the Bluetooth peripheral device responds to the user's answer control operation, the Bluetooth peripheral device may generate a second answer instruction and send the second answer instruction to the electronic device.

[0103] If the Bluetooth peripheral responds to the user's rejection control operation, the Bluetooth peripheral can generate a rejection instruction and send the rejection instruction to the electronic device. The rejection control operation can be a voice control operation or a touch control operation, and the touch control operation can be a touch control operation of the user on the rejection control on the Bluetooth peripheral.

[0104] Optionally, after receiving the second call request, the Bluetooth peripheral device may further identify the incoming call number carried in the second call request, determine an audio signal corresponding to the incoming call number, and play the audio signal.

[0105] Step 212: The electronic device responds to the second answering instruction, connects the second call, exchanges audio data with the Bluetooth peripheral device, and disconnects from the mobile terminal.

[0106] In an embodiment of the present application, after receiving the second answering instruction sent by the Bluetooth peripheral, the electronic device can respond to the second answering instruction, connect the second call, exchange audio data with the Bluetooth peripheral, and disconnect from the mobile terminal.

[0107] That is, the mobile terminal can answer the second call in response to the second answering instruction, send the audio data of the second call to the Bluetooth peripheral device, so that the Bluetooth peripheral device outputs the audio data, and receive the audio data of the second call sent by the Bluetooth peripheral device, even if the Bluetooth peripheral device inputs the audio data.

[0108] Step 213: If the electronic device receives a call hang-up instruction sent by the Bluetooth peripheral, it hangs up the second call and re-establishes a Bluetooth protocol connection with the mobile terminal.

[0109] In the embodiment of the present application, during the process of exchanging data with the Bluetooth peripheral device, if the electronic device receives a call hang-up instruction sent by the Bluetooth peripheral device, the second call can be hung up, and a Bluetooth protocol connection can be re-established with the mobile terminal. If the call hang-up instruction sent by the Bluetooth peripheral device is not received, the audio data of the second call can continue to be exchanged with the Bluetooth peripheral device.

[0110] The call hang-up instruction may be generated by the Bluetooth peripheral in response to a hang-up control operation of the user.

[0111] Optionally, the process of re-establishing a Bluetooth protocol connection between the electronic device and the mobile terminal may include: the electronic device may send a connection establishment request to the mobile terminal, and after the mobile terminal receives the connection establishment request, it may send a connection establishment response to the electronic device. At this point, the electronic device can re-establish a Bluetooth protocol connection with the mobile terminal.

[0112] Afterwards, if the first call request sent by the electronic device is received again, step 205 and subsequent steps may be executed.

[0113] At present, more and more people have multiple mobile terminals. For example, the multiple mobile terminals may include an electronic device, a mobile terminal and a Bluetooth peripheral. Usually, the mobile terminal can be projected to the electronic device to realize the multi-screen collaboration and call collaboration functions between the mobile terminal and the electronic device. When the electronic device is not around while charging, the method provided in the embodiment of the present application can be used to bridge the mobile terminal and the Bluetooth peripheral. Therefore, when the mobile terminal has an incoming call, the user can also answer the call through the Bluetooth peripheral, avoiding missed calls and improving the user experience.

[0114] It should be noted that the electronic device can only establish a Bluetooth protocol connection with the mobile terminal, that is, the electronic device and the mobile terminal exchange audio data through the first audio path. In this case, the receiver (or speaker, etc.) of the mobile terminal can be used as an output device for audio data, and the microphone of the mobile terminal can be used as an input device for audio data.

[0115] The electronic device can also establish a Bluetooth protocol connection with the Bluetooth peripheral only, that is, the electronic device and the mobile terminal exchange audio data through the second audio path. In this case, the receiver (or speaker, etc.) of the Bluetooth peripheral can be used as an output device for audio data, and the microphone of the Bluetooth peripheral can be used as an input device for audio data.

[0116] For the above-mentioned multiple application scenarios, the electronic device can determine the current application scenario based on the device to which it is connected, and send corresponding instructions to the audio switching circuit to configure the first audio path and the second audio path, thereby ensuring that the electronic device can be suitable for different application scenarios.

[0117] For example, if the electronic device detects that it is connected to the mobile terminal and the Bluetooth peripheral device respectively, it can send a connection instruction to the audio switching circuit. After receiving the connection instruction, the audio switching circuit can complete the bridging configuration of the first audio path and the first audio path. In addition, after receiving the connection instruction, the audio switching circuit can also update its flag bit to the first flag bit to indicate that the current role of the electronic device is the AG role and the HF role. Among them, the flag bit can be used to indicate the current application scenario of the electronic device.

[0118] If the electronic device detects that it is only connected to the mobile terminal, that is, the electronic device is disconnected from the Bluetooth peripheral, a first disconnection instruction can be sent to the audio switching circuit. After receiving the first disconnection instruction, the audio switching circuit determines that there is no need to perform a bridging configuration of the audio path. In addition, after receiving the first disconnection instruction, the audio switching circuit can update the current first flag bit to the second flag bit to indicate that the current role of the electronic device is the HF role.

[0119] If the electronic device detects that it is only connected to the Bluetooth peripheral device, that is, the electronic device is disconnected from the mobile terminal, a second disconnection instruction can be sent to the audio switching circuit. After receiving the second disconnection instruction, the audio switching circuit determines that there is no need to perform a bridging configuration of the audio path.
