detailed description

The Bluetooth Special Interest Group (SIG) specifies different protocols or services (profiles) for communication between Bluetooth devices. Common protocols include Bluetooth Audio Distribution Profile (A2DP), HFP, etc. Among them, Bluetooth hands-free phone service (hands-free profile, HFP) protocol, which is mainly used for voice transmission between Bluetooth devices. For example, Bluetooth devices can control phone calls, such as answering, hanging up, rejecting, and voice dialing.

HFP protocol defines two roles of audio gateway (audio gateway, AG) and hands-free component (hand free, HF).

As the input/output gateway of audio, the AG is responsible for monitoring incoming calls on the network, informing the peer HF of the incoming call status, and establishing a standard synchronous connection oriented (SCO) or enhanced (Enhanced) connection. SCO streams voice. In this embodiment of the present application, the device serving as the AG is also called a gateway device.

As the remote audio input/output device of the audio gateway, HF is the receiving end of the call, responsible for answering the call instructions sent by the AG, accepting the establishment of the SCO stream, and providing several remote control functions (such as answering, hanging up, rejecting, voice dialing) Wait). In the embodiments of the present application, the device used as HF is also called a hands-free device.

The roles of devices that support the HFP protocol are generally fixed. For example, a mobile phone is fixed as a gateway device, and a Bluetooth device (such as a smart watch, smart glasses, Bluetooth headset, etc.) is fixed as a hands-free device.

Figure 1 provides a flowchart of a method for establishing an HFP connection between a mobile phone and a Bluetooth device, including:

S11. The mobile phone initiates a Bluetooth pairing request to the Bluetooth device;

For example, when the mobile phone receives the user's first operation for the Bluetooth device, it can click the identification of the Bluetooth device in the scan list;

S12, the Bluetooth device returns a response message indicating successful pairing to the mobile phone;

If the Bluetooth device is not connected to other devices via Bluetooth, the Bluetooth device accepts the Bluetooth pairing request and returns a response message indicating successful pairing to the mobile phone; or,

If the Bluetooth device is not connected to other devices by Bluetooth, the Bluetooth device returns a response message indicating that the pairing is successful to the mobile phone after receiving the instruction to agree to the Bluetooth pairing request. For example, after receiving the Bluetooth pairing request, the Bluetooth device displays a Bluetooth pairing request pop-up window on the display interface. The pop-up window includes the relevant information of the Bluetooth pairing requester (such as the Bluetooth name of the mobile phone), and also includes the information used to agree to the Bluetooth pairing. Function controls, function controls for rejecting Bluetooth pairing, etc. When the mobile phone receives the user's second operation on the function control for agreeing to Bluetooth pairing in the pop-up window, the mobile phone accepts the Bluetooth pairing request and returns a message indicating that the pairing is successful. Response message to the phone.

After the mobile phone establishes a physical connection with the Bluetooth device, it can negotiate capabilities and view the services supported by the Bluetooth device, such as HFP, A2DP, etc.;

S13. The mobile phone sends an HFP service discovery request to the Bluetooth device;

In some embodiments, the mobile phone can also query the services supported by the Bluetooth device, and the Bluetooth device reports the Bluetooth services supported by itself according to the query request.

S14, the Bluetooth device sends a response message to the mobile phone, reporting the role (HP) of the Bluetooth device.

After the process of the above steps S11-S14, the mobile phone and the Bluetooth device successfully negotiate roles, the mobile phone will be used as a gateway device, and the Bluetooth device will be used as a hands-free device. When the mobile phone receives an incoming call from the network side, the mobile phone will notify the Bluetooth device of the status of the incoming call, and the user can control answering, hanging up or rejecting the incoming call through the Bluetooth device; Bluetooth device for voice dialing.

In some embodiments, since the Bluetooth device can usually retain the MAC address of the last or last connected device, when the Bluetooth device receives the user's operation of turning on the Bluetooth function or gets close to the last connected Bluetooth device, it can directly communicate with the last connected device. When the connected Bluetooth device is connected via Bluetooth, the roles of both parties can also directly use the previously negotiated roles.

With the continuous development of terminal technology, some Bluetooth devices can have the function of accessing the communication network and providing users with voice call services. For example, a subscriber identity module (SIM) card or an embedded SIM card (embedded-SIM, eSIM) is set on the Bluetooth device. For the convenience of description, the SIM card and the eSIM card are collectively referred to as a phone card hereinafter.

Specifically, the ways for the Bluetooth device to access the communication network and provide the user with the function of voice call service can include the following three ways:

1. The phone number of the Bluetooth device is different from the phone number of the mobile phone.

For a communication network, when it provides a call service to a Bluetooth device and a mobile phone, the Bluetooth device and the mobile phone are two different telephone devices respectively.

When there is an incoming call from the mobile phone, the communication network only sends the incoming call notification to the mobile phone. At this time, if the mobile phone and the Bluetooth device are successfully paired and the HFP connection is maintained, the Bluetooth device can display and control the incoming call of the mobile phone. If the pairing is not successful or there is no HFP connection, Then the Bluetooth device cannot sense the incoming call from the mobile phone.

When there is an incoming call from a Bluetooth device, the communication network only sends an incoming call notification to the Bluetooth device. Since the Bluetooth device is in the HF role, the mobile phone cannot sense the incoming call from the Bluetooth device, nor can it control the incoming call from the Bluetooth device.

Taking a mobile phone and a smart wearable device as an example, the smart wearable device has an independent phone number (supports inserting a SIM card or supports an independent eSIM). Without Bluetooth connection, the smart wearable device can initiate and receive calls as a stand-alone device. 2. The phone number of the Bluetooth device is the same as the phone number of the mobile phone.

Specifically, a Bluetooth device is equipped with a phone card, but the phone number of the phone card is the same as the phone number of the mobile phone. For the communication network, when the Bluetooth device and the mobile phone are the same phone device. When there is an incoming call from the phone number, both the mobile phone and the Bluetooth device can receive the incoming call and display the incoming call, and the user can choose any device to answer or reject the incoming call.

Taking a mobile phone and a smart wearable device as an example, the smart wearable device and mobile phone A have opened the No. 1 dual terminal service, that is, the phone number of mobile phone A is written in the esim of the smart wearable device. Mobile phone A responds together. In the actual use process, the user can use the mobile phone B to connect with the smart wearable device through Bluetooth.

The third type, the Bluetooth device has two calling cards, one of the calling cards (card 1) has the same phone number as the mobile phone, and the other calling card (card 2) has a different phone number from the phone.

If there is an incoming call from card 1, it is equivalent to the second case above, that is, for the communication network, the Bluetooth device and the mobile phone are the same telephone device, and both the mobile phone and the Bluetooth device can receive the incoming call from card 1 and display the incoming call, Users can choose any device to answer or reject incoming calls.

If there is an incoming call from card 2, it is equivalent to the first case above, and if there is an incoming call from card 1, it is equivalent to the second case above, that is, for the communication network, the Bluetooth device and the mobile phone are two different phones. equipment. For the incoming call of card 2, the communication network only sends an incoming call notification to the Bluetooth device. Since the Bluetooth device is in the HF role, the mobile phone cannot sense the incoming call from the Bluetooth device, nor can it control the incoming call from the Bluetooth device.

For the first scenario above and the scenario in which the smart watch uses the phone service of card 2 in the third scenario, it is referred to in this article as the scenario where the Bluetooth device has an independent cellular communication function, that is, the phone number of the Bluetooth device is the same as that of the mobile phone. different phone numbers.

As mentioned above, the HFP protocol stipulates that after the Bluetooth pairing of two devices is successful, the role of the HFP device supported by both parties is fixed, so when the mobile phone receives an incoming call, the user can choose to answer it on the mobile phone (AG), or Choosing to answer on the Bluetooth device (HF) that is successfully paired with the mobile phone Bluetooth means that when the mobile phone receives an incoming call, it can be controlled by the Bluetooth device, that is, the HF device can control the AG device, but when the HF device also has an independent When the cellular communication function is used, that is, the phone number of the HF device is different from the phone number of the mobile phone. Although the HF device and the AG device were connected by Bluetooth before, the AG device will not control the call function of the HF device. When the Bluetooth device receives an incoming call, Based on the HFP protocol, it can only be answered on a Bluetooth device.

However, in practical applications, the hardware capability of HF is usually not as good as that of AG. For example, equipment manufacturers usually set the mobile phone to AG and the wearable device to HF, which will lead to the recording effect of the HF microphone (microphone, MIC). And speakers (speakers, SPK) playback effect is poor; in addition, many HF Bluetooth devices (such as car terminals, smart watches, etc.) audio output is external, so there are privacy issues in public places. Therefore, when the user uses the HF call, there is a problem of poor user experience.

In order to improve the experience effect of a user using a Bluetooth device to make a call, the present application provides a call method, device and system. This application implements Bluetooth through proprietary Bluetooth communication protocols, such as serial port profile (SPP) of traditional Bluetooth technology or Generic Attribute Profile (GATT) of Bluetooth low energy (BLE), etc. When the device (HF) calls, transfer the functions of the Bluetooth device such as incoming calls and answering to the mobile phone that is successfully paired with the Bluetooth device, so that the user can use the mobile phone's MIC to collect sound and use the mobile phone's SPK to play the sound, and achieve the same hardware cost. to improve the user's call experience. It should be understood that the embodiments of the present application are mainly aimed at a scenario in which a Bluetooth device has an independent cellular communication function (ie, a scenario in which the Bluetooth device and the mobile phone have different numbers).

The implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Specifically, the smart watch 300 initiates a Bluetooth pairing request to the mobile phone 400, and the mobile phone 400 accepts the Bluetooth pairing request and returns a response message indicating successful pairing to the smart watch 300. Module or Bluetooth chip 307) and the Bluetooth component in the mobile phone 400 (BT in the wireless communication module 406 in FIG. 4) are paired successfully; or, the mobile phone 400 initiates a Bluetooth pairing request to the smart watch 300, and the smart watch 300 accepts the Bluetooth pairing request, and return a response message indicating that the pairing is successful to the mobile phone 400, and the Bluetooth component in the smart watch 300 and the Bluetooth component in the mobile phone 400 are successfully paired. After the smart watch 300 and the mobile phone 400 are successfully paired by Bluetooth, the Bluetooth component of the smart watch 300 and the Bluetooth component of the mobile phone 400 can perform short-distance data interaction, that is, the Bluetooth connection between the smart watch 300 and the mobile phone 400 is successfully established.

In some embodiments, two-dimensional code information may be generated in the smart watch 300, which may be prefabricated at the factory. The two-dimensional code information includes the Bluetooth pairing information of the smart watch 300, and the smart phone 400 can perform Bluetooth connection by scanning.

After the smart watch 300 and the mobile phone 400 are successfully paired via Bluetooth, the smart watch 300 and the mobile phone 400 also establish an HFP link, and negotiate that the smart watch 300 is a hands-free device, the mobile phone 400 is a gateway device, and the HFP link is between the smart watch 300 and the mobile phone 400 will remain connected for the duration of the Bluetooth connection. In this way, when the mobile phone 400 calls, the smart watch 300 can also control the phone call of the mobile phone 400, such as answering, hanging up, rejecting the incoming call, and voice dialing.

For example, after the mobile phone 400 receives an incoming call, the mobile phone 400 can notify the smart watch 300 of the incoming call information based on the HFP link, so as to transfer the incoming call to the smart watch 300, and the smart watch 300 will perform a reminder for the incoming call of the mobile phone 400, and the user You can choose to answer the incoming call on the smart watch 300. If the smart watch 300 receives the answering operation, the smart watch 300 controls the mobile phone 400 to answer the incoming call. The mobile phone 400 establishes a SCO link with the smart watch 300 based on the HFP protocol, and communicates with each other based on the SCO link. Transmit voice data. The mobile phone 400 can send the voice data of the call originator to the smart watch through the SCO link, which is output by the smart watch 300. The smart watch 300 can also collect the voice in the surrounding environment to generate the voice data of the call receiver, and pass the voice data of the call receiver through the smart watch 300. The SCO link is sent to the mobile phone 400, and then the mobile phone 400 transmits the voice data of the incoming call receiving end to the incoming call originating end through the network device.

Of course, the user can also choose to answer the incoming call on the mobile phone 400. If the mobile phone 400 receives the answering operation, the mobile phone 400 answers the incoming call, the voice data of the call originating end is output by the mobile phone 400, and the mobile phone 400 collects the voice in the surrounding environment to generate the voice data of the incoming call receiving end. voice data, and transmit the voice data of the incoming call receiving end to the incoming call originating end through the network device.

After the smart watch 300 and the mobile phone 400 are successfully paired by Bluetooth, the smart watch 300 and the mobile phone 400 also establish a private data communication link based on the private Bluetooth communication protocol. It should be understood that the data communication link is a bidirectional link, that is, the mobile phone 400 can send data to the smart watch 300 based on the link, and the smart watch 300 can also send data to the mobile phone 400 based on the link. In addition, the data communication link will remain connected during the Bluetooth connection period between the smart watch 300 and the mobile phone 400 .

Exemplarily, after the Bluetooth pairing of the smart watch 300 and the mobile phone 400 is successful, an SPP link is established between the Bluetooth component in the smart watch 300 and the Bluetooth component in the mobile phone 400, and the SPP link can be used to transmit the Bluetooth based on the SPP protocol. Communication data, that is, the transmission of packets encapsulated in the SPP protocol format.

Exemplarily, after the smart watch 300 and the mobile phone 400 are successfully paired with Bluetooth, and after successfully binding with the target Bluetooth device through step S3, the Bluetooth component in the smart watch 300 and the Bluetooth component in the mobile phone 400 are established. The BLE GATT link can be used to transmit Bluetooth communication data based on the BLE GATT protocol, that is, to transmit messages encapsulated in the BLE GATT protocol format.

It should be understood that the above-mentioned SPP link and BLE GATT link are only two possible examples and are not limited. During specific implementation, any data communication link that supports bidirectional communication can be applied to the present application.

In the embodiment of the present application, the smart watch 300 has the function of independently accessing the communication network and providing the user with a voice call service. For example, a phone card (which can be a SIM card or an eSIM card) can be set on the smart watch 300 separately, and the phone number of the phone card is different from the phone number of the phone card on the mobile phone 400, and the smart watch 300 can access the mobile communication independently through the phone card network, and independently receive incoming calls from the mobile communication network based on the calling card to provide users with voice calling services.

S502 , the smart watch 300 receives an incoming call from the network device 23 .

It should be understood that the incoming call here is an incoming call received from the network device 23 when the smart watch 300 is used as a separate telephone device, and the phone number of the incoming call receiver of the incoming call is different from that of the mobile phone 400 .

In the embodiment of the present application, the smart wearable device has an independent phone number (supports inserting a SIM card or supports an independent eSIM), and the smart wearable device can initiate and receive calls as an independent device.

S503. The smart watch 300 determines that it has established a Bluetooth connection with the mobile phone 400, and generates an incoming call notification message.

The format of the incoming call notification message matches the private data communication link established in the aforementioned S501.

For example, if the smart watch 300 and the mobile phone 400 are connected through the SPP link, the specific format of the incoming call notification message is the format of the SPP message. The information content carried by the incoming call notification message may be, for example, the content shown in Table 1.

Table 1 Incoming call notification messages

TransID

message id

caller name

caller number

CRC

Among them, TransID is the identification of the transmission packet corresponding to the incoming call notification message, indicating the ID description of the transmission from one endpoint to another endpoint. Different senders and receivers have different TransIDs.

The message ID is the identifier of the message, and the message IDs corresponding to different messages transmitted by the same sender and receiver may be different.

It should be understood that the content exemplified in Table 1 is only an example of the content of the incoming call notification message, but not a limitation, and may actually include more content, such as the caller's name, number attribution information, operator information, etc., the embodiment of the present application. There is no restriction on this.

Optionally, after receiving an incoming call, the smart watch 300 will display a first incoming call interface, and the first incoming call interface may display incoming call information, function icons or controls, and the like.

Exemplarily, as shown in FIG. 6A , the first incoming call interface may display incoming call information including the incoming call number ("186...5212"), the number origin (Shandong Qingdao), the operator (China Mobile), etc. Including icons or controls such as SMS, Reminder, Reject, and Answer). By operating these icons or controls, the smart watch 300 can be triggered to perform corresponding functions. For example, the display screen of the smart watch 300 receives a click operation for the "answer" icon, and the display screen of the smart watch 300 reports the operation to the smart watch. The processor of the watch 300 and the processor of the smart watch 300 can control the incoming call and control the display interface of the display screen to switch from the first incoming call interface to the in-call interface, so that the smart watch 300 is in a voice call state.

S504 , the smart watch 300 sends the incoming call notification message to the mobile phone 400 through the Bluetooth connection, and the mobile phone 400 receives the incoming call notification message through the Bluetooth connection.

Specifically, after the smart watch 300 generates the above-mentioned incoming call notification message, it first transmits the incoming call notification message to the Bluetooth component in the smart watch 300, and the Bluetooth component in the smart watch 300 sends the incoming call notification message through the aforementioned private data communication link to the Phone 400. The Bluetooth component in the mobile phone 400 receives the incoming call notification message and transmits it to the processor in the mobile phone 400 .

Exemplarily, the private data communication link established by the smart watch 300 and the mobile phone 400 may be an SPP link, and the Bluetooth component in the smart watch 300 may transmit the incoming call notification message to the Bluetooth component in the mobile phone 400 through the SPP link.

S505 , the mobile phone 400 performs an incoming call reminder in response to the incoming call notification message.

Exemplarily, if the private data communication link established by the smart watch 300 and the mobile phone 400 is an SPP link, the processor of the mobile phone 400 can parse the incoming call notification message according to the format of the SPP protocol to obtain the specific content of the incoming call notification message, It is determined that the watch 300 has received an incoming call, and then an incoming call reminder is executed according to the specific content in the incoming call notification message.

Optionally, performing the incoming call reminder on the mobile phone 400 may include: displaying a second incoming call interface on the display screen of the mobile phone 400 .

The second incoming call interface may include incoming call information and function icons. As shown in FIG. 6B , the second call interface includes caller information such as caller number, number location information, and operator information, and may also include function icons such as a short message icon, a reminder icon, a reject icon, and an answer icon. Operations on these function icons can trigger the mobile phone 400 to control the smart watch 300 to perform corresponding functions, so as to realize the effect of remotely controlling the smart watch 300 through the mobile phone 400 .

Optionally, in order to distinguish the incoming call from the mobile phone 400 itself and the incoming call from the smart watch 300 , the second incoming call interface may also display a prompt message to prompt that the current incoming call is the incoming call from the smart watch 300 . For example, as shown in FIG. 6B , the second incoming call interface may further include the text identification information of “watch call”; or, as shown in FIG. 6C , the second incoming call interface may further include an icon of “watch”, It is used to indicate that the current incoming call is an incoming call from the smart watch 300 . Of course, FIG. 6B and FIG. 6C are only two possible examples of the prompt information, but are not limited, and are not actually limited thereto.

Optionally, when the mobile phone 400 performs an incoming call reminder, it may also include reminder methods such as vibration, ringing, or indicator light, and the specific examples are as follows.

Example 1, the processor of the mobile phone 400 controls the motor 491 to vibrate, which is used for vibrating alerts for incoming calls.

Optionally, in order to distinguish an incoming call from the mobile phone 400 itself and an incoming call from the smart watch 300 , the processor of the mobile phone 400 can control the motor to vibrate at different frequencies when the mobile phone 400 itself and the smart watch 300 receive an incoming call.

Example 2, the processor of the mobile phone 400 controls the speaker 470A of the mobile phone 400 to play the ringtone of the incoming call.

Optionally, in order to distinguish the incoming call of the mobile phone 400 itself from the incoming call of the smart watch 300, when the mobile phone 400 itself calls and when the smart watch 300 calls, the processor of the mobile phone 400 can control the speaker 470A of the mobile phone 400 to play different sounds respectively. B.

Example 3, the processor of the mobile phone 400 controls the indicator light of the mobile phone 400 to turn on.

Optionally, in order to distinguish the incoming call of the mobile phone 400 itself from the incoming call of the smart watch 300, when the mobile phone 400 itself calls and when the smart watch 300 calls, the processor of the mobile phone 400 can control different indicator lights to turn on, or the mobile phone 400 to turn on. The processor of the mobile phone 400 can control the indicator lights to display different colors respectively, or the processor of the mobile phone 400 can control the indicator lights to flash at different frequencies.

For example, the processor of the mobile phone 400 can control the indicator light to display green when the mobile phone 400 calls itself, and to display yellow when the smart watch 300 calls.

It should be understood that, in this embodiment of the present application, both the mobile phone 400 and the smart watch 300 can perform an incoming call alert, or only the mobile phone 400 can perform an incoming call alert, which is not limited in this application.

In the case where both the mobile phone 400 and the smart watch 300 perform the incoming call reminder, the present application does not limit the order in which the mobile phone 400 and the smart watch 300 both perform the incoming call reminder.

For example, the smart watch 300 performs an incoming call notification immediately after receiving an incoming call, and at the same time, generates an incoming call notification message and sends the incoming call notification message to the mobile phone 400, and the mobile phone 400 performs the incoming call notification after receiving the incoming call notification message. In this case , the smart watch 300 can perform an incoming call reminder before the mobile phone 400 .

Further, when the mobile phone 400 receives the call notification message and starts to perform the call notification, the smart watch 300 can continue to perform the call notification, such as continuing to display the first call interface, or stop performing the call notification, such as switching the display state, such as FIG. 6D . As shown, the smart watch 300 switches from displaying the second incoming call interface to turning off the screen.

Optionally, the smart watch 300 can set whether to continue to perform an incoming call reminder after the incoming call is transferred to the mobile phone 400 .

Exemplarily, as shown in FIG. 6E , the setting menu of the incoming call reminder can be selected in the “settings” program of the smart watch 300, and then the function of “continue reminder after incoming call forwarding” can be turned on or off in the setting menu of the incoming call reminder. operate. If the smart watch 300 receives the operation of enabling the function of "continue prompting after incoming call forwarding" on the setting menu display interface, the smart watch 300 enables the function of "continuing prompting after incoming call transfer". The watch 300 will continue to perform incoming call reminder. If the smart watch 300 receives an operation to turn off the function of "continue prompting after incoming call forwarding" on the setting menu display interface, the smart watch 300 turns off the function of "continue prompting after incoming call transfer". The watch 300 will stop calling reminders. When the smart watch 300 is factory-set, the "continue prompt after incoming call transfer" function can be enabled or disabled by default.

In some embodiments, the mobile phone 400 is installed with a first application, such as "Huawei Sports Health", the application may include a first interface, and the interface includes a smart wearable device paired with the mobile phone 400, such as the smart watch 300, When receiving the user's operation on the smart watch 300, a second interface may also be displayed, and the second interface includes setting options for the smart watch 300, such as the option of "continue prompting after incoming call transfer". operation, when the mobile phone 400 is performing the incoming call alert, the smart watch 300 will continue to perform the incoming call alert; the interface may also include the option of “call notification message push”, that is, when the smart watch 300 receives an incoming call, it can push the incoming call alert synchronously to phone side.

The above describes how the smart watch 300 transfers incoming calls to the mobile phone 400 , and the following describes how the mobile phone 400 controls the incoming calls of the smart watch 300 .

Specifically, after the above step S505, the mobile phone 400 can also control the smart watch 300 to answer the call, hang up the call, or reject the incoming call in response to the received operation.

The methods for answering a call, hanging up a call, and rejecting an incoming call are described in detail below.

1. Answer the phone

Referring to FIG. 7, after the above step S505, it further includes:

S506A, the mobile phone 400 receives the answering operation.

Illustratively, referring to FIG. 8A , it is a schematic diagram of displaying a second incoming call interface for the mobile phone 400 . The second incoming call interface includes an answering icon. When the touch sensor or pressure sensor of the mobile phone 400 detects the operation on the answering icon, a touch event is generated and reported to the processor of the mobile phone 400. After the processor of the mobile phone 400 receives the touch event, An answering instruction is generated in response to the touch event.

It should be understood that the present application does not specifically limit the specific implementation manner of the answering operation. The answering operation (touching the answering icon) shown in FIG. 8A is only an example and not a limitation, and other methods may actually be used. For example, the answering operation is still when the mobile phone 300 is shaken, the power button of the mobile phone 300 is pressed, or a voice command is received.

Optionally, the specific format of the answering instruction is an SPP message or an HFP message, etc., which is not limited here.

S507A, the mobile phone 400 sends the answering instruction to the smart watch 300 through Bluetooth, and the smart watch 300 receives the answering instruction.

Specifically, the processor of the mobile phone 400 transmits the answering instruction to the Bluetooth module of the mobile phone 400, and the Bluetooth module of the mobile phone 400 can send the answering instruction to the Bluetooth module of the smart watch 300 based on the SPP link, BLE GATT link or HFP link, etc. , the Bluetooth module of the smart watch 300 transmits the answering instruction to the processor of the smart watch 300 .

S508A, the smart watch 300 is connected to the call originator.

S509A, mobile phone 400 and smart watch 300 establish SCO flow.

It should be understood that the mobile phone 400 and the smart watch 300 establish a SCO flow, and it can also be said that the mobile phone 400 and the smart watch 300 establish a SCO connection.

Based on the HFP protocol, the SCO flow should be established by the AG device (ie the handset 400). Correspondingly, the specific implementation process of step S509A may include: the mobile phone 400 initiates a request to the smart watch 300 to establish a SCO stream, and after receiving the "OK" response sent by the smart watch, the mobile phone 400 opens a correspondingly set synchronous connection to complete the SCO stream. establishment.

The S510A, the mobile phone 400 and the smart watch 300 transmit voice data to each other based on the SCO stream, and the smart watch 300 and the network device 23 transmit voice data to each other, so that the mobile phone 400 can control the call of the smart watch 300 .

Specifically, after receiving the voice data from the call originator (such as another mobile phone or watch), the network device 23 transmits the voice data from the call originator to the smart watch 300. After the smart watch 300 receives the voice data from the call originator, it will not The voice data of the call originator is output directly, but is transmitted to the mobile phone 400 through the SCO stream. After receiving the voice data, the mobile phone 400 outputs the voice data of the call originator through the audio output device (such as SPK) of the mobile phone 400. At the same time, the MIC of the mobile phone 400 also collects the voice in the surrounding environment, generates the voice data of the incoming call receiver, and then transmits the voice data of the incoming call receiver to the smart watch 300 through the SCO stream, and then the smart watch 300 transmits the voice data of the incoming call receiver. It is sent to the call originator through the network device 23 .

In the embodiment of the present application, after the mobile phone 400 controls the smart watch 300 to connect with the call originator, the mobile phone 400 can switch the display screen to the off-screen state, or display the lock screen interface, or display the in-call interface, or display other applications The interface of the program (such as the desktop), etc., is not limited here.

For example, referring to FIG. 8B , which is a schematic diagram of a mobile phone 400 displaying an in-call interface, the in-call interface includes call duration, caller information (caller number, attribution, incoming call from the watch, etc.), function icons for controlling the call status (mute, hang up, etc.) , hands-free, etc.).

During the call, the mobile phone 400 can also detect the user's operation to control the display state of the switch screen.

Exemplarily, after the smart watch 300 connects with the call originator, the mobile phone 400 displays the in-call interface by default. During the call, the mobile phone 400 detects that an object is approaching near the mobile phone 400 based on the distance sensor 480F or the proximity light sensor 480G. When gradually being blocked, it is determined that the user's posture is to hold the mobile phone 400 close to the ear to answer the call. In this case, the mobile phone 400 can switch the display screen to the off-screen or lock-screen state to avoid user misoperation.

In the embodiment of the present application, after the mobile phone 400 controls the smart watch 300 to connect with the call originator, the smart watch 300 can switch the display screen to the off-screen state, or display the lock screen interface, or display the in-call interface, or display other The interface of the application (such as the desktop), etc., is not limited here.

For example, referring to FIG. 8B , during a call, the smart watch 300 is in an off-screen state. Because the user may not pay attention to the smart watch 300 when using the mobile phone 400 to answer a call, turning off the screen of the smart watch 300 at this time can avoid leakage of the user's call privacy.

For example, referring to FIG. 8C , during a call, the smart watch 300 displays the desktop, which facilitates the user to use other functions of the smart watch 300 while using the mobile phone 400 to answer the call of the smart watch 300 , thereby improving the user experience.

Optionally, when the mobile phone 400 outputs the voice data of the originating end of the call, it may be output through SPK, or may be output through earpiece or earphone, which is not limited in this embodiment of the present application. For example, after the call is connected, the mobile phone 400 outputs the voice data of the call originator through the handset by default to protect the privacy of the user. , and the mobile phone outputs the voice data through SPK.

The above S506A-S510A describe the method in which the mobile phone 400 controls the smart watch 300 to connect the incoming call and make a call after the call reminder of the smart watch 300 is transferred to the mobile phone 400 . In practical applications, it is not excluded that the smart watch 300 is used to answer the incoming call after the call reminder of the smart watch 300 is transferred to the mobile phone 400 .

In this case, the smart watch 300 and the mobile phone 400 may not establish a SCO stream (ie, do not transmit voice data to each other), and after the smart watch 300 receives an incoming call, the mobile phone 400 stops the call reminder.

As shown in FIG. 8D , after the smart watch 300 receives an incoming call from the network side, both the smart watch 300 and the mobile phone 400 perform an incoming call reminder for the incoming call. When the smart watch 300 receives the answering operation and connects to the incoming call, the smart watch 300 displays the in-call interface, and the smart watch 300 plays the voice data of the call originator and collects the voice data and transmits it to the call originator. After the smart watch 300 is connected to an incoming call, it can also send an instruction to instruct the mobile phone 400 to stop the incoming call alert. After the mobile phone 400 receives the instruction, it stops the incoming call alert, and the display interface can be switched from the incoming call interface to the lock screen or off-screen interface. Or restore the display interface before the call reminder. Optionally, the mobile phone 400 may also display a prompt message that the incoming call has been connected through the smart watch. As shown in FIG. 8D , the mobile phone 400 displays “An incoming call of 186...5212 has been answered through the watch”.

According to the above S501~S505 and S506A~S510A, it can be seen that:

When the HF device (such as the smart watch 300) receives an incoming call, the HF device can notify the AG device (such as the mobile phone 400) of the incoming call based on the SPP or BLE GATT protocol, triggering the AG device to perform an incoming call reminder for the incoming call from the HF device, thereby realizing the The effect of transferring incoming calls from HF equipment to AG equipment. Further, the AG device can also establish a SCO stream with the HF device based on the HFP protocol (wherein the establishment of the SCO stream is initiated by the AG device), thereby achieving the effect of using the AG device to answer the call of the HF device.

When the AG device (such as the mobile phone 400) receives an incoming call, the AG device can notify the smart HF device (such as the watch 300) of the incoming call based on the HFP protocol, triggering the HF device to perform an incoming call reminder for the AG device's incoming call, thereby realizing the AG device. The effect of call transfer to HF device. Further, the AG device can also establish a SCO stream with the HF device based on the HFP protocol (where the establishment of the SCO stream is initiated by the AG device), thereby achieving the effect of using the HF device to answer the call of the AG device.

2. Hang up the phone

There are two situations in which the call receiver hangs up and the call originator hangs up:

The first type, the incoming call receiver actively hangs up the call. Referring to FIG. 9, after the above step S510A, it further includes:

S511A, the mobile phone 400 receives the hang-up operation.

Exemplarily, referring to FIG. 10A , as described above, a hang-up icon may be displayed on the in-call interface of the mobile phone 400, and a touch event is generated when the touch sensor or pressure sensor of the mobile phone 400 detects a touch operation for the hang-up icon. It is reported to the processor of the mobile phone 400, and the processor generates a hang-up instruction in response to the touch event.

It should be understood that the present application does not specifically limit the operation of hanging up the phone, and the hanging up operation shown in FIG. 10A is only an example and not a limitation, and there may be other ways for specific implementation. For example, the hang-up operation may also be that the mobile phone 400 is shaken, the power button of the mobile phone 400 is pressed, and the mobile phone 400 receives a voice command.

It should be understood that the display interface of the watch 300 in FIG. 10A is an example of an interface during a call, and may actually be other display interfaces, such as a lock screen, a desktop, etc., or an off-screen state, which is not limited here.

Optionally, the specific format of the hang-up command is an SPP message or an HFP message, which is not limited here.

S512A, the mobile phone 400 sends a hang-up instruction to the smart watch 300.

Exemplarily, the Bluetooth module of the mobile phone 400 may send the hang-up instruction to the smart watch 300 through the SPP link or the HFP link.

The S513A and the smart watch 300 hang up the call with the call originator.

The S514A, the mobile phone 400 and the smart watch 300 disconnect the SCO data path.

Specifically, the mobile phone 400 (AG device) closes the synchronization connection correspondingly set above, and disconnects the previously established SCO stream.

In this embodiment of the present application, after the mobile phone 400 hangs up the call, the mobile phone 400 can switch the display interface, for example, from the in-call interface to the end-of-call interface (the end-of-call interface contains relevant information about the call, such as the duration of the call, the incoming call number, etc.), or switch to the lock screen interface, or restore to the interface before the call, or the mobile phone 400 screen off, etc., there are no restrictions here.

For the smart watch 300, if the smart watch 300 displays the in-call interface during the call, after the mobile phone 400 hangs up the call, the smart watch 300 can switch the display interface, for example, from the in-call interface to the end-of-call interface (the end of the call). The interface contains the relevant information of the call, such as call duration, caller ID, etc.), or switch to the lock screen interface, or restore to the interface before the call, or the mobile phone 400 screen off, etc., there are no restrictions here. If the smart watch 300 displays another interface (such as the lock screen or the desktop) during the call, the smart watch 300 can switch the display state or not switch the display state after the call, which is not limited here.

For example, assuming that the interface of the mobile phone 400 and the smart watch 300 before the call is as shown in FIG. 2 , as shown in FIG. 10A , after the mobile phone 400 is used to hang up the call, both the mobile phone 400 and the smart watch 300 return to the interface before the call.

The above S511A-S514A describe the method of controlling the smart watch 300 by the mobile phone 400 to end the call after the call is connected. In practical applications, it is not excluded that the smart watch 300 is still used to control the end of the call.

As shown in FIG. 10B , during the call, the smart watch 300 and the mobile phone 400 respectively display the in-call interface, and the in-call interface of the smart watch 300 includes a hang up icon. After receiving the operation for the hang-up icon, the smart watch 300 hangs up the call with the call originator, and disconnects the SCO data path from the mobile phone 400 .

After the smart watch 300 hangs up the call, the smart watch 300 can switch the display interface, for example, from the in-call interface to the end-of-call interface (the end-of-call interface contains relevant information about the call, such as the duration of the call, the number of the incoming call, etc.), or Switch to the lock screen interface, or restore to the interface before the call, or the mobile phone 400 screen off, etc., there are no restrictions here.
