When the network-side device receives a call for the mobile terminal When requested, the network side device can transfer the call request for the mobile terminal to the answering terminal, so that the answering terminal can answer the call to the mobile terminal. But in this way, once the user turns on the call forwarding function of the mobile terminal, all calls made to the mobile terminal will be forwarded to the answering terminal. If the user wants to continue to use the mobile terminal to answer calls, but forgets to turn off the call forwarding function, many calls will be missed. phone, causing inconvenience to users.

2. The user can connect the mobile terminal to the headset or speaker through Bluetooth or Wi-Fi technology. When the mobile terminal receives an incoming call, the mobile terminal will transfer the incoming call and voice call to the headset or speaker by default, and use the headset or speaker. Capture the user's voice. When the user needs to use the mobile terminal to make a call, the mobile terminal needs to receive the user's selection input to switch the call back to the mobile terminal, which causes complicated operation steps for the user, and in the process of switching the voice call, the user easily Missing part of the call content caused inconvenience to the user.

In view of the above problems, the present application proposes a voice communication method, which realizes that after the terminal receives a voice call, if the terminal is occupied or does not answer the call after a timeout, the terminal can select from other terminals capable of calling in the home local area network, according to each terminal. voice capability parameters (such as voice capability priority m, call frequency n, user voice energy value x, user location value y, device status value s, etc.), determine the optimal answering terminal, and transfer incoming calls to voice calls to the answering terminal. In this way, by transferring the incoming call and the voice call between the various call terminals in the family, it is avoided that the user misses the voice call on the call terminal, and the user experience is improved.

The following introduces a network architecture provided by an embodiment of the present application.

Please refer to FIG. 2 , which shows a schematic diagram of a network architecture 200 provided in an embodiment of the present application. As shown in FIG. 2, the network architecture 200 includes a plurality of terminals. The terminal may include a smart phone 201, a smart watch 202, a smart speaker 203, a personal computer 204, a smart TV 205, a tablet computer 206, etc., which is not limited in this application.

Wherein, the multiple terminals can all have the ability to talk, and the multiple terminals can receive calls and make calls in the following ways: 1. The multiple terminals can receive calls from the circuit switched domain (CS domain, CS domain) in the mobile communication network. ) for incoming calls or calls. 2. The multiple terminals can receive incoming calls or calls based on the VoLTE technology in an IP multimedia subsystem (IP multimedia subsystem, IMS) in the mobile communication network. 3. The multiple terminals can receive incoming calls or calls from the Internet (Internet) based on the VoIP technology.

The multiple terminals can all be connected to a local area network (LAN) through a wired or wireless fidelity (wireless fidelity, WiFi) connection. For the structure of the terminal in the network architecture 200, reference may be made to the terminal 100 shown in FIG. 1, which is not repeated here. For example, the multiple terminals are connected to the same router.

In a possible implementation manner, the local area network of the network architecture 200 further includes a central device 207, and the central device 207 can communicate with multiple terminals in the network architecture 200 (for example, the terminal 201, the terminal 202, the terminal 203, and the terminal 204). , Terminal 205 and Terminal 206.) are connected. The central device 207 may be a router, a gateway, an intelligent device controller, or the like. The central device 207 may include a memory, a processor and a transceiver, and the memory may be used to store respective voice capability parameters of the multiple terminals (eg, voice capability priority m, call frequency n, voiceprint energy value x, user location value y, device state value s, etc.). The processor can be used to determine the answering terminal from the respective voice capability parameters of multiple terminals when a terminal connected to the local area network needs to transfer an incoming call. A transceiver may be used to communicate with the plurality of terminals connected to the local area network.

In a possible implementation manner, the network architecture 200 further includes a server 208, where the server 208 may be a server in a smart home cloud network, the number of which is not limited to one, but may be multiple, which is not limited here. Wherein, the server 208 may include a memory, a processor and a transceiver, wherein the memory may be used to store respective voice capability parameters of the multiple terminals (for example, voice capability priority m, call frequency n, voiceprint energy value x, User location value y, device state value s, etc.). The transceiver can be used to communicate with each terminal in the local area network. The processor can be used to process the data acquisition request of each terminal in the local area network, and instruct the transceiver to deliver the respective voice capability parameters of the multiple terminals to each terminal.

In the following, a voice communication method provided by an embodiment of the present application is explained in detail with reference to the network architecture 200 shown in FIG. 2 and an application scenario. In this embodiment of the present application, a terminal that receives an incoming voice call may be referred to as a first terminal, and a terminal that receives an incoming call may be referred to as a second terminal.

In some application scenarios, there are multiple terminals capable of calling in the local area network in the home, such as smart phones, smart watches, smart speakers, personal computers, smart TVs, and smart tablets. A user can receive a voice call through any terminal (such as a smart phone). When the user does not answer for a long time, or the calling device is already occupied (for example, during a call), the user may miss an incoming call, causing inconvenience to the user. Therefore, the embodiment of the present application provides a voice communication method. After the terminal 1 (such as a smart phone) receives an incoming call, when the terminal 1 times out and does not receive an answering operation from the user or the terminal is already occupied (such as during a call) , the terminal 1 can determine the answering terminal (such as a smart phone) according to the voice capability parameters of other terminals (such as voice capability priority m, call frequency n, voiceprint energy value x, user location y, device status value s, etc.). TV), and transfer the incoming call to the answering terminal (such as a smart TV). In this way, the user can be prevented from missing an incoming call on the terminal, thereby improving the user experience.

Referring to FIG. 3 , FIG. 3 shows a voice communication method provided in an embodiment of the present application. Wherein, the local area network may include N terminals with call capability, where N is an integer greater than 2. A local area network refers to a computer network in which N terminals with call capability are connected to a router. Wherein, multiple terminals with call capability in the local area network may be bound to the same user account. In the embodiment shown in FIG. 3 , any terminal that receives an incoming call may be referred to as terminal 1 . For example, when a smart phone receives an incoming call, the smart phone can be referred to as terminal 1, and when a smart TV receives an incoming call, the smart TV can be referred to as terminal 1, which is not limited herein. As shown in Figure 3, the method includes:

S301. Terminal 1 receives an incoming call.

The incoming call may refer to a voice incoming call. The terminal of the contact (that is, the terminal that initiates the call) can make a voice call to the terminal 1 through the CS domain in the mobile communication network, and the terminal of the contact can also make a voice call based on the VoLTE technology to the terminal 1 through the IMS network in the mobile communication network, The terminal of the contact person can also make a voice call based on the VoIP technology to the terminal 1 through the Internet (Internet).

S302, the terminal 1 outputs an incoming call reminder.

After receiving the call from the contact's terminal, the terminal 1 can output an incoming call reminder. The incoming call reminder may include at least one of the following: a ringtone reminder, a mechanical vibration reminder, and an incoming call display reminder (for example, the terminal 1 displays the contact information of the contact on the display screen, etc.).

In S303, the terminal 1 determines whether the call transfer function is enabled, and if so, in S304, the terminal 1 establishes a connection with other terminals in the local area network. If not, the terminal 1 does not establish a connection with other terminals in the local area network.

The terminal 1 may receive a user's setting input before receiving an incoming call from the contact, and in response to the user's setting input, the terminal 1 may enable or disable the call transfer function. In this way, the terminal 1 can transfer the received incoming call according to the user's requirement, which improves the user's experience. Understandably, the call transfer function is to transfer the incoming call or voice call received by the terminal to other terminals, and the other terminal will remind the incoming call, and/or collect the user's voice, and play the caller (ie the contact) voice. When terminal 1 enables the call transfer function, terminal 1 receives an incoming call and needs to transfer the incoming call, then the incoming call received by terminal 1 is transferred to other terminals, and the other terminal will remind the incoming call. When the other terminal detects the user After answering the incoming call, terminal 1 transfers the voice call to other terminals. When the call transfer function is enabled on the terminal 1, and the terminal 1 is making a voice call and needs to transfer the call, the terminal 1 transfers the voice call to another terminal.

After the terminal 1 determines that the call transfer function has been enabled, the terminal 1 can establish a connection with other terminals (terminal 2, terminal 3, . . . , terminal N) in the local area network. The connection may be a connection based on the TCP/IP protocol. Under the connection based on the TCP/IP protocol, the terminal 1 may transfer incoming calls (including calls and voice calls) to the transfer device based on the VoIP technology. The connection may be Wi-Fi Direct. The connection can also be a connection established through a router. If the two devices support the Bluetooth function, the connection may also be a Bluetooth connection, and so on. In this way, after the terminal 1 determines that the incoming call needs to be transferred, it can transfer the incoming call to the transfer device (for example, the terminal 2) in time, without requiring the user to wait too much time, and reducing the delay caused by transferring the incoming call.

In a possible implementation manner, if the terminal 1 obtains the voice capability parameters of other terminals from the hub device or the server, the terminal 1 may only establish a connection with the switching device after determining the answering device. In this way, the terminal 1 only establishes a connection with the switching device, thereby reducing wireless resource consumption.

In S305, the terminal 1 judges whether the incoming call is overtime and is not answered or whether the terminal 1 is occupied, and if so, in S306, the terminal 1 obtains the voice capability parameters of other terminals in the local area network.

After the terminal 1 establishes a connection with other terminals in the local area network, the terminal 1 can first determine whether the terminal 1 has been occupied, and if so, the terminal 1 can obtain the If the voice capability parameter is not occupied, the terminal 1 can determine whether the user's answering operation has not been received for more than a specified time threshold (for example, 10s) after receiving an incoming call. If there is no answer after the specified time threshold, the terminal 1 acquires the voice capability parameters of the other terminals (terminal 2, terminal 3, . . . , terminal N). The voice capability parameters include: voice capability priority m, call frequency n, voiceprint energy value x, user location value y, and device state value s. in:

1. The voice capability priority m is used to indicate the call effect of the terminal. The better the call effect of the terminal, the higher the voice capability priority. For example, the voice capability priority m of terminal 1 may be 1, and the voice capability priority n of terminal 2 may be 0.5, which means that the call effect of terminal 1 is better than that of terminal 2. The voice capability priority of a terminal is determined by the type of terminal. Exemplarily, the corresponding relationship between the terminal type and the terminal voice capability value may be as shown in Table 1 below:

Table 1

As can be seen from Table 1 above, the voice capability value of a smartphone terminal can be 1, that of a tablet terminal can be 0.8, that of a smart speaker terminal can be 0.6, and that of a smart TV terminal can be 0.6. The capability value may be 0.5, the voice capability value of the smart watch type terminal may be 0.4, and the voice capability value of the personal computer type terminal may be 0.3. The content shown in Table 1 above is only used to explain the present application and should not be construed as a limitation.

2. The call frequency n is used to indicate the frequency with which the terminal connects to voice calls. The larger the call frequency n is, the more frequently the terminal connects to voice calls. The call frequency n may be the ratio of the number of calls of the terminal to the total number of calls of all terminals in the local area network. Wherein, any terminal in the local area network may periodically (for example, the period may be a week, a month, etc.) send the number of calls to other terminals. The terminal may determine the total number of calls of all terminals in the local area network after receiving the respective number of calls of other terminals. Exemplarily, it is assumed that there are 6 terminals in the local area network, which are a smart phone, a tablet computer, a smart speaker, a smart TV, a smart watch, and a personal computer. The number of calls and the call frequency n of these six terminals can be shown in Table 2 below:

Table 2

terminal number of calls call frequency n smart phone 80 0.4 tablet 20 0.1 smart speaker 20 0.1 Smart TV 60 0.3 smart watch 10 0.05 personal computer 10 0.05

As can be seen from Table 2 above, the number of calls made by smartphones is 80, that of tablet computers is 20, that of smart speakers is 20, that of smart TVs is 60, that of smart watches is 10, and that of personal computers is 10. The number of calls is 10. Among them, the total number of calls of the six terminals in the local area network is 200. Therefore, a smartphone has a call frequency of 0.4, a tablet has a call frequency of 0.1, a smart speaker has a call frequency of 0.1, a smart TV has a call frequency of 0.3, a smart watch has a call frequency of 0.05, and a PC has a call frequency of 0.05. The content shown in Table 2 above is only used to explain the present application, and should not be construed as a limitation.

3. The voiceprint energy value x is used to indicate the loudness of the user's voice received by the terminal. The larger the voiceprint energy value is, the closer the user is to the terminal. The terminal may collect sounds in real time through a microphone, and the terminal calculates the user's voiceprint energy value according to the collected sounds. Exemplarily, it is assumed that there are 6 terminals in the local area network, which are a smart phone, a tablet computer, a smart speaker, a smart TV, a smart watch, and a personal computer. The user voice capability value x collected by the six terminals can be shown in Table 3 below:

table 3

As can be seen from Table 3 above, the voiceprint energy value of a smartphone is 0.23, that of a tablet is 0, that of a smart speaker is 0.25, that of a smart TV is 0.55, and that of a smart watch is 0.55. The voiceprint energy value is 0.5 for the PC and 0 for the PC. The content shown in Table 3 above is only used to explain the present application and should not be construed as a limitation.

4. The user location value y is used to represent the location relationship between the terminal and the user. For example, when the user location value y is 1, it means that the user is around the terminal. When the user location value y is 0, it means that the terminal does not detect that the user is around the terminal. The terminal can obtain the image around the terminal through the camera, and detect from the image whether the user and the terminal are in the same position in the family layout map (for example, both are in the bedroom), if so, the user position value y of the terminal is 1; if If not, the user location value y of the terminal is 0. The camera may be the camera of the terminal itself, or may be a separate camera connected to the local area network. When the camera is a separate camera connected in the local area network, after the camera obtains the user's location (eg, in the bedroom), the camera can send the user's location (eg, in the bedroom) to each terminal in the local area network. When the terminal does not have the ability to obtain the user's location (for example, the camera is damaged or not equipped with a camera), the user location y of the terminal is 0.5. Exemplarily, it is assumed that there are 6 terminals in the local area network, which are a smart phone, a tablet computer, a smart speaker, a smart TV, a smart watch, and a personal computer. Among them, the smart phone can be in the master bedroom, the smart speaker can be in the second bedroom 1, the tablet computer can be in the second bedroom 2, and the smart TV and smart watch can be in the living room. When the user is in the living room, the user location value y collected by these six terminals can be shown in Table 4 below:

Table 4

terminal User location value y smart phone 0 tablet 0 smart speaker 0.5 Smart TV 1 smart watch 1 personal computer 0

It can be seen from Table 4 above that the user location value y of the smartphone is 0, which means that the user is not around the smartphone. The user location value y of the tablet is 0, indicating that the user is not around the smartphone. The user location value y of the smart TV is 1, indicating that the user is around the smart TV. The user position y of the smart watch is 1, which means that the user is around the smart watch. The user position y of the PC is 0, indicating that the user is not around the PC. The content shown in Table 4 above is only used to explain the present application and should not be construed as a limitation.

5. The device state value s is used to indicate whether the terminal is currently available for answering a voice call. When the terminal is currently in an idle state and can be used to answer a voice call, the device state value s is 1. When the terminal is currently in an occupied state, for example, the terminal is in a voice call, the device state value s is 0.5. When the terminal is currently in an unavailable state, for example, the terminal has turned off the call transfer function, that is, the terminal does not receive calls transferred from other terminals, and the device state value s is 0. Wherein, the terminal may receive the user's input, turn off the call access function, and the terminal may also turn off the call transfer function when a call is in progress, which is not limited herein. Exemplarily, it is assumed that there are 6 terminals in the local area network, which are a smart phone, a tablet computer, a smart speaker, a smart TV, a smart watch, and a personal computer. The device status values s of these six terminals can be shown in Table 5 below:

table 5

terminal Device status value s smart phone 1 tablet 0.5 smart speaker 1 Smart TV 1 smart watch 1 personal computer 0

It can be seen from Table 5 above that the device status value s of the smart phone is 1, which means that the smart phone can currently be used to answer voice calls. The device state value s of the tablet computer is 0.5, which means that the tablet computer is currently in an occupied state (for example, in a call). The device status value s of the smart speaker is 1, which means that the smart speaker can currently be used to answer voice calls. The device status value s of the smart TV is 1, which means that the smart TV can currently be used to answer voice calls. The device status value s of the smart watch is 1, which means that the smart watch can currently be used to answer voice calls. The device status value s of the personal computer is 0, which means that the smart watch is currently unavailable for receiving voice calls.

In a possible implementation manner, the respective voice capability parameters of the other terminals are stored in the local memory of the other terminals. For example, the voice capability parameters of terminal 2 are stored in the local storage of terminal 2, the voice capability parameters of terminal 3 are stored in the local storage of terminal 3, ..., the voice capability parameters of terminal N are stored in the local storage of terminal N. Terminal 1 can send an acquisition command of the voice capability parameter to other terminals (terminal 2, terminal 3, ..., terminal N) in the local area network, and other terminals (terminal 2, terminal 3, ..., terminal N) receive the voice capability After the parameter acquisition instruction, the respective voice capability parameters can be sent to the terminal 1 .

In a possible implementation manner, the respective voice capability parameters of other terminals are stored on the central device in the local area network. Each terminal in the local area network can send its own voice capability parameter to the central device 207 . When the terminal 1 determines that the incoming call exceeds the specified time threshold and has not received the user's answering operation or the terminal 1 is already occupied (for example, during a call), the terminal 1 can send an acquisition instruction of the voice capability parameter to the central device 207 . After receiving the voice capability parameter acquisition instruction, the central device 207 may send the voice capability parameters of other terminals (terminal 2 , terminal 3 , . . . , terminal N) to terminal 1 .

In a possible implementation manner, the respective voice capability parameters of other terminals are stored on the server 208 of the smart home cloud. Each terminal in the local area network can be connected to the server 208 , and each terminal in the local area network can send respective voice capability parameters to the server 208 . When the terminal 1 judges that the incoming call exceeds the specified time threshold and has not received the user's answering operation or the terminal 1 is already occupied (for example, during a call), the terminal 1 can send the server 208 a voice capability parameter acquisition instruction. After receiving the instruction for acquiring the voice capability parameter, the server 208 may send the voice capability parameters of other terminals (terminal 2, terminal 3, . . . , terminal N) to terminal 1 .

The following describes how the terminal 1 determines the answering terminal for outgoing call transfer.

S307: Terminal 1 determines the answering terminal according to the voice capability parameters of other terminals. Wherein, the answering terminal is used to receive the incoming call transferred by the terminal 1 .

The voice capability parameter may include a voice capability priority m, a call frequency n, a voiceprint energy value x, a user location value y, and a device state value s. For the text description of the speech capability parameter, reference may be made to the foregoing embodiments, and details are not repeated here.

In a possible implementation manner, terminal 1 can screen out devices that can currently conduct a call (that is, a terminal whose device status value s is 1) from other terminals, such as terminal 2, terminal 3, ..., terminal N, and the current can make calls. Terminal 1 may first compare the respective voiceprint energy values x of other terminals. If there is only one terminal (for example, terminal 2) with the largest voiceprint energy value x among the terminals (terminal 2, terminal 3, . The terminal (for example, terminal 2) is determined to be the answering terminal.

If there are multiple terminals (for example, terminal 2, terminal 3, terminal 4, and terminal 5) with the largest voiceprint energy value x among the terminals (terminal 2, terminal 3, . The magnitudes of the respective user location values y of the multiple terminals with the largest voiceprint energy value x (for example, terminal 2, terminal 3, terminal 4, and terminal 5) may be compared. If there is only one terminal (for example, terminal 2) with the largest user position value y among the multiple terminals with the largest voiceprint energy value x (for example, terminal 2, terminal 3, terminal 4, and terminal 5), then terminal 1 may The terminal (eg, terminal 2) with the largest energy value x and the largest user location value y is determined as the transfer terminal.

If the multiple terminals with the largest voiceprint energy value x (for example, terminal 2, terminal 3, terminal 4, and terminal 5) have multiple terminals with the largest user location value y (for example, terminal 2, terminal 3, and terminal 4), then The terminal 1 can compare the respective call frequencies n of the terminals with the largest sound energy value x and the largest user location value y (for example, terminal 2, terminal 3, and terminal 4). If there is only one terminal (for example, terminal 2) with the largest call frequency n among the multiple terminals with the largest voiceprint energy value x and the largest user location value y (for example, terminal 2, terminal 3, and terminal 4), the terminal may The terminal (for example, terminal 2) with the largest voiceprint energy value x, the largest user position y, and the largest call frequency n (for example, terminal 2) is determined as the transfer terminal.

If the multiple terminals with the largest voiceprint energy value x and the largest user position y (such as terminal 2, terminal 3 and terminal 4) have multiple terminals (such as terminal 2 and terminal 3) with the largest call frequency n (such as terminal 2 and terminal 3), then terminal 1 The voice capability priority m of each terminal (eg, terminal 2 and terminal 3) with the largest voice energy value x, the largest user location value y, and the largest call frequency n can be compared. If there is only one terminal (such as terminal 2) with the highest voice capability priority m (such as terminal 2) among the multiple terminals with the largest voiceprint energy value x, the largest user location value y and the largest call frequency n (such as terminal 2 and terminal 3), then The terminal may determine the terminal (for example, terminal 2) with the largest sound energy value x, the largest user location y, the largest calling frequency n, and the largest voice capability priority m (eg, terminal 2) as the answering terminal.

If there are multiple terminals with the largest voice energy value x, the largest user location y, the largest calling frequency n, and the largest voice capability priority m, the terminal 1 can randomly select a terminal from the multiple terminals as the answering terminal.

It can be understood that the terminal 1 can determine the user's location according to the user's voiceprint energy value x and/or the user's location value y. The terminal 1 can determine the answering terminal according to one or more of the user's location, the voice capability priority m, the call frequency n, and the device state value s. For example, the terminal 1 may only determine the answering terminal (for example, the terminal 2) according to the voiceprint capability value x. The answering terminal is the one with the largest voiceprint capability value x among other terminals except terminal 1 . For another example, the terminal 1 may determine the answering terminal (for example, the terminal 2 ) according to the voiceprint capability value x and the call frequency n. The answering terminal is the one with the largest voiceprint capability x and the largest call frequency n among other terminals except terminal 1 .

In a possible implementation manner, the terminal 1 may calculate the respective switching capability values V of other terminals according to the following formula (1). in:

V=f(a*m, b*n, c*x, d*y)*s Formula (1)

Among them, m is the voice capability priority, n is the call frequency, x is the voiceprint energy value, y is the user location value, s is the device status value, a is the voice capability priority weight, b is the call frequency weight, c is the weight of the voiceprint capability value, and d is the weight of the user position value. f(z1, z2, z3, z4) is an operation function, wherein the operation function f(z1, z2, z3, z4) can be a summation function. which is,

V=(a*m+b*n+c*x+d*y)*s Formula (2)

After the terminal 1 calculates the respective voice capability values V of the other terminals (terminal 2, terminal 3, .

Wherein, the above-mentioned voice capability parameter (voice capability priority m or call frequency n or voiceprint energy value x or user location value y) has a greater influence on the determination result of the listening terminal, and its weight is greater. For example, the impact on the determination of the listening terminal: the voiceprint energy value x is greater than the user location value y is greater than the call frequency n is greater than the voice capability priority m, then c>d>b>a. In a possible implementation manner, the respective weights of the speech capability parameters are variable. Any terminal in the local area network can receive the user's input operation and reset the respective weights of the voice capability parameters.

The following formula (2) is used to exemplarily introduce how to determine the answering terminal according to the voice capability parameter.

Exemplarily, as shown in FIG. 4 , there may be 6 terminals with call capability in the home LAN, such as smart phone 201 , smart watch 202 , smart speaker 203 , personal computer 204 , smart TV 205 , and tablet computer 206 .

The location, the smart TV 205 is located at the living room position of the family floor plan, and the tablet computer 206 is located at the second bedroom 2 position of the family floor plan. When the smart phone 201 receives an incoming call, the user is in the living room of the family floor plan, which is the same position as the smart watch 202 and the smart TV 205 are.

Among them, the voice capability parameters of each terminal in the home LAN (voice capability priority m, call frequency n, voiceprint energy value x, user location value y, device status value s) can be shown in Table 6 below:

The voice capability priority m ₅ of the smart TV 205 is 0.5, the call frequency n ₅ of the smart TV 205 is 0.3, the voiceprint energy value x ₅ of the smart TV 205 is 0.55, the user location value y ₅ of the smart TV 205 is 1, and the smart TV 205 has a voiceprint energy value x 5 of 0.55.

Since the switching capability value _V5 of the smart TV 205 is 0.585, the switching capability value in other terminals (smart watch 202, smart speaker 203, personal computer 204, smart TV 205 and tablet computer 206) is the largest, and the smart phone 201 can It is determined that the smart TV 205 is the answering terminal. The above examples are only used to explain the present application, and should not be construed as limitations. During the specific implementation process, any device in the home local area network can receive an incoming call, which will not be repeated here.

In another example, as shown in FIG. 5 , there may be 6 terminals capable of calling in the home local area network, such as a smart phone 201 , a smart watch 202 , a smart speaker 203 , a personal computer 204 , a smart TV 205 , and a tablet computer 206 .

When the smart phone 201 receives an incoming call, the user may be at the balcony of the home floor plan, which is different from the location of each terminal in the home local area network. Wherein, each terminal in the home local area network cannot obtain the voiceprint energy value x and the user location value y.

Among them, the voice capability parameters of each terminal in the home LAN (voice capability priority m, call frequency n, voiceprint energy value x, user location value y, device status value s) can be shown in Table 7 below:

For example, the weight value a corresponding to the voice capability priority m may be 0.1, the weight value b corresponding to the call frequency n may be 0.2, the weight value c corresponding to the voiceprint energy value x may be 0.5, and the user location value y The corresponding weight value d may be 0.2.

When the smart phone 201 receives an incoming call and acquires the voice capability parameters of other terminals, the smart phone 201 can calculate the switching capability value V of the other terminals through the above formula (2). For example, the switching capability value V ₂ of the smart watch 202 is 0.05, the switching capability value V ₃ of the smart speaker 203 is 0.08, the switching capability value V ₄ of the personal computer 204 is 0, and the switching capability value V of the smart TV 205 ₅ is 0.055, and the switching capability value V ₆ of the tablet computer 206 is 0.05. Since the switching capability value _V3 of the smart speaker 203 is 0.08, the switching capability value in other terminals (smart watch 202, smart speaker 203, personal computer 204, smart TV 205 and tablet computer 206) is the largest, and the smart phone 201 can It is determined that the smart speaker 203 is the answering terminal. The above examples are only used to explain the present application, and should not be construed as limitations. During the specific implementation process, any device in the home local area network can receive an incoming call, which will not be repeated here.

In a possible implementation manner, the terminal 1 may receive an input operation (such as voice input, etc.) from the user before determining the answering terminal according to the voice capability parameters of other terminals in the above step S307, The incoming call is forwarded to the designated terminal in the local area network. Exemplarily, as shown in FIG. 6 , there may be 6 terminals with call capability in the home LAN, such as smart phone 201 , smart watch 202 , smart speaker 203 , personal computer 204 , smart TV 205 , and tablet computer 206 . The smart phone 201 is located at the master bedroom position of the family floor plan, the smart watch 202 is located at the living room position of the family floor plan, the smart speaker 203 is located at the second bedroom 1 position of the family floor plan, and the personal computer 204 is located in the study room of the family floor plan. The location, the smart TV 205 is located at the living room position of the family floor plan, and the tablet computer 206 is located at the second bedroom 2 position of the family floor plan. When the smart phone 201 receives an incoming call, the smart phone 201 can receive the user's voice input (for example, "Xiaoyi Xiaoyi, transfer to the living room TV"), and in response to the voice input, the smart phone 201 can forward the received incoming call to the smart TV 205 in the living room. The above examples are only used to explain the present application and should not be construed as limitations.

In a possible implementation manner, the above steps S306 and S307 may be performed by a central device or a server. That is, the central device or the server can acquire the voice capability parameters of each terminal in the local area network. The central device or server may determine the answering terminal according to the voice capability parameters of other terminals except terminal 1 . Then, the central device or the server can send the identification of the answering terminal (for example, the IP address of the terminal 2 ) to the terminal 1 .

The following describes the process of the terminal 1 transferring the incoming call to the receiving terminal (terminal 2).

S308: Terminal 1 sends an incoming call instruction to terminal 2.

Since the terminal 1 and other terminals are connected through the local area network, the terminal 1 can send the incoming call instruction to the terminal 2 through the local area network.

S309, the terminal 2 outputs an incoming call reminder.

After the terminal 2 receives the incoming call instruction sent by the terminal 1, in response to the incoming call instruction, the terminal 1 can output an incoming call reminder. The incoming call reminder output by the terminal 2 may include at least one of the following: a ringtone reminder, a mechanical vibration reminder, and an incoming call display reminder (for example, the terminal 2 displays the contact information of the contact on the display screen, etc.).

In a possible implementation manner, in order to prevent an incoming call from the same contact from outputting an incoming call reminder on two terminals at the same time, after terminal 2 receives the incoming call instruction sent by terminal 1, terminal 2 can return the call confirmation information to terminal 1, After receiving the call confirmation information, the terminal 1 can stop outputting the call reminder.

S310. The terminal 2 may receive the answering operation of the user. In response to the user's answering operation, S311 , the terminal 2 may return answering confirmation information to the terminal 1 .

After the terminal 2 outputs the incoming call reminder, the terminal 2 can receive the answering operation of the user (for example, click the answer button displayed on the screen of the terminal 2 or click the answer physical button on the terminal 2), and in response to the answering operation, the terminal 2 can return the answer confirmation to terminal 1. In response to the answering confirmation, the terminal 1 can transfer the voice to the terminal 2.

The following specifically describes the process of transferring the voice call to the answering terminal (terminal 2 ) after the terminal 1 receives the answering confirmation information returned by the terminal 2 .

S312. The terminal 1 receives the voice data of the contact.

in:

1. CS domain voice call: The contact's terminal can collect the contact's voice, establish a call connection with the terminal 1 through the CS domain in the mobile communication network, and send the voice signal to the terminal 1.

2. VoLTE voice call: The terminal of the contact can collect the voice of the contact, and use the voice compression algorithm to compress and encode the voice of the contact to generate the voice data of the contact. Then, the voice data is encapsulated into a voice data packet, and the contact's voice data packet is sent to the terminal 1 through the IMS in the mobile communication network.

3. VoIP voice call: the terminal of the contact can collect the voice of the contact, compress and encode the voice of the contact through the voice compression algorithm, generate the voice data of the contact, and then encapsulate the voice data through the IP protocol and other related protocols into voice data packets, and send the contact's voice data packets to terminal 1 through the Internet.

S313 , the terminal 1 sends the voice data of the contact to the terminal 2 .

Wherein, when the voice call transferred by the terminal 1 is a CS domain voice call, after receiving the voice signal of the contact, the terminal 1 can compress and encode the voice signal of the contact through a voice compression algorithm to generate the voice of the contact Data, and encapsulate the voice data into voice data packets through IP protocol and other related protocols. Then, the terminal 1 sends the voice data packet of the contact to the terminal 2 through the local area network.

When the voice call transferred by terminal 1 is a VoLTE voice call or a VoIP voice call, after receiving the voice data packet of the contact, terminal 1 can forward the voice data packet of the contact to terminal 2 through the local area network.

S314. After receiving the voice data of the contact, the terminal 2 plays the voice data of the contact.

After receiving the voice data packet of the contact sent by the terminal 1, the terminal 2 can acquire the voice data of the contact from the voice data packet of the contact, and play the voice data of the contact.

S315. The terminal 2 collects the sound through the microphone to generate the voice data of the user.

S316 , the terminal 2 sends the user's voice data to the terminal 1 .

In step S311, after the terminal 2 returns the answering confirmation to the terminal 1, the terminal 2 can continuously collect the user's voice and the surrounding environment through the microphone. The terminal 2 can compress and encode the sound collected by the microphone (including the user's voice and the surrounding environment sound) through the voice compression algorithm, generate the user's voice data, and encapsulate the user's voice data into a voice. data pack. Then, the terminal 2 sends the user's voice data packet to the terminal 1 through the local area network.

S317: After receiving the user's voice data sent by the terminal 2, the terminal 1 sends the user's voice data to the terminal of the contact.

in,

When the voice call transferred by terminal 1 is a voice call in the CS domain, after receiving the user's voice data sent by terminal 2, terminal 1 converts the user's voice data into the user's voice signal, and transmits the user's voice signal through mobile The CS domain in the communication network is sent to the terminal of the contact. After receiving the user's voice signal sent by the terminal 1, the terminal of the contact can parse the user's voice from the user's voice signal and play it.

When the voice call transferred by terminal 1 is a VoLTE voice call, after receiving the user's voice data sent by terminal 2, terminal 1 can forward the user's voice data to the contact's terminal through the IMS. After receiving the user's voice data, the terminal of the contact can play the user's voice data.

When the voice call transferred by terminal 1 is a VoIP voice call, after receiving the user's voice data sent by terminal 2, terminal 1 can forward the user's voice data to the contact's terminal through the Internet. After receiving the user's voice data, the terminal of the contact can play the user's voice data.

The above steps S312-S314 and S315-S317 have no order, and the same is also true in the following embodiments.

In some possible implementations, the above steps S313 and S316 may be forwarded via a central device or a server.

In some application scenarios, there are multiple terminals capable of calling in the local area network in the home, such as smart phones, smart watches, smart speakers, personal computers, smart TVs, and smart tablets. The user makes a voice call with the contact through any terminal (eg smartphone). Since many terminals in the home local area have poor mobility and cannot move according to the user, when the user moves around the home, the voice call effect of the terminal will deteriorate. Therefore, the embodiment of the present application provides a voice communication method. When a user communicates with a contact through a terminal 1 (such as a smart phone), the terminal 1 can make a call according to the voice capability parameters of other terminals (for example, the voice capability priority m). frequency n, voiceprint energy value x, user location y, terminal state value s, etc.), determine the answering terminal (such as a smart TV) of the voice call, and transfer the voice call to the answering terminal (such as a smart TV), so, In the process of the user moving indoors, the call effect between the user and the contact can be improved.

Referring to FIG. 7 , FIG. 7 shows a voice communication method provided in an embodiment of the present application. Wherein, the local area network may include N terminals with call capability, where N is an integer greater than 2. In the embodiment shown in FIG. 7, any terminal that is talking can be called terminal 1. For example, a user is using a smart When the mobile phone is talking with the contact, the smart phone can be called the terminal 1, and when the user is using the smart TV to talk with the contact, the smart TV can be called the terminal 1, which is not limited herein. As shown in Figure 7, the method includes:

S701. The terminal 1 establishes a connection with other terminals in the local area network.

Terminal 1 can establish a connection with other terminals (terminal 2, terminal 3, . , the terminal 1 can transfer incoming calls (including calls and conversations) to the transfer device based on the VoIP technology. The connection may also be Wi-Fi Direct. The connection can also be a connection established through a router. If the two devices support the Bluetooth function, the connection may also be a Bluetooth connection.

In a possible implementation manner, if the terminal 1 obtains the voice capability parameters of other terminals from the hub device or the server, the terminal 1 may only establish a connection with the switching device after determining the answering device. In this way, the terminal 1 only establishes a connection with the switching device.

S702. The terminal 1 conducts a voice call with the terminal of the contact.

The device state value s ₆ of the computer 206 is one. The above Table 13 is only used to explain the present application and should not be construed as a limitation.

For example, the weight value a corresponding to the voice capability priority m may be 0.1, the weight value b corresponding to the call frequency n may be 0.2, the weight value c corresponding to the voiceprint energy value x may be 0.5, and the user location value y The corresponding weight value d may be 0.2.

The smart phone 201 can calculate the switching capability value V of each other terminal according to the above formula (2). The transfer capability value V ₁ of the smart phone 201 is 0.28, the transfer capability value V ₂ of the smart watch 202 is 0.5, the transfer capability value V ₃ of the smart speaker 203 is 0.23, and the transfer capability value V of the personal computer 204 ₄ is 0, the switching capability value V ₅ of the smart TV 205 is 0.61, and the switching capability value V ₆ of the tablet computer 206 is 0.275. Since the switching capability value _V5 of the smart TV 205 is 0.61, the switching capability value in each terminal (smart phone 201, smart watch 202, smart speaker 203, personal computer 204, smart TV 205 and tablet computer 206) is the largest, The smart phone 201 can determine that the smart TV 205 is the answering terminal. Thus, the smart phone 201 can transfer the voice call to the smart TV 205 . The above examples are only used to explain the present application and should not be construed as limitations.

In a possible implementation manner, after the terminal 1 determines the answering terminal, it can determine whether the switching capability value V of the answering terminal is higher than the switching capability value V of the current calling terminal by a specified threshold (for example, 0.2), and if so, Then the terminal 1 transfers the voice call to the answering terminal. Illustratively, for example, the specified threshold may be 0.2. The transfer capability value of the answering terminal (for example, terminal 2) is 0.61, and the transfer capability value V of the current calling terminal (for example, terminal 3) is 0.23. The difference of the receiving capacity value V (ie 0.23) is 0.38, which is higher than the specified threshold (ie 0.2). Therefore, the terminal 1 can transfer the voice call to the answering terminal. In this way, frequent switching of the calling device can be avoided.

In a possible implementation manner, the terminal 1 can detect the voiceprint energy of the user after determining the answering terminal, and the voiceprint energy is below a specified voiceprint energy threshold (for example, 10 dB) and lasts for a certain period of time (for example, 0.5 seconds). ), terminal 1 transfers the call to the answering terminal. In this way, since the user's voiceprint energy is the smallest at the end of each sentence during the user's speech, when the user's voiceprint energy is less than a certain threshold, the transfer call can be switched, which can avoid that the call terminal collects the user's data during the transfer call. The speech is incomplete.

That is, the central device or the server can acquire the voice capability parameters of each terminal in the local area network. The central device or server may determine the answering terminal according to the voice capability parameters of other terminals. Then, the central device or the server can send the identification of the answering terminal (for example, the IP address of the terminal 2 ) to the terminal 1 .

In some possible implementations, the above steps S707 and S710 may be forwarded via a central device or a server.

In some application scenarios, the terminal 1 may be talking with the terminal of the contact A, and at this time, the terminal 1 may receive an incoming call from the terminal of the contact B again. Since terminal 1 cannot talk with terminals of more than two contacts at the same time, in a possible implementation manner, terminal 1 can determine the incoming call of the terminal of contact B through the above-mentioned embodiment shown in FIG. 3 . In the step of answering the terminal, the answering terminal (for example, terminal 2) is determined. In addition, the terminal 1 can transfer the incoming call from the terminal of the contact B to the answering terminal (for example, the terminal 2), and the answering terminal communicates with the terminal of the contact B. In a possible implementation manner, terminal 1 may transfer the voice call with contact A's terminal to an answering terminal (for example, terminal 2), and terminal 1 answers the incoming call from contact B's terminal. The process of transferring a call or a call by the terminal 1 may refer to the foregoing embodiment shown in FIG. 3 or FIG. 7 , which will not be repeated here. In this way, missed calls can be avoided, and user experience can be improved.

In some application scenarios, there may be multiple terminals with call capability in the local area network. At the same time, there may also be a central device in the local area network. The central device has a routing function. When terminal 1 receives the VoIP voice dialed by the terminal of the contact through the Internet When making a phone call, the voice data packets between the terminal 1 and the contact's terminal during the call need to be transferred through the central device. When terminal 1 is occupied or fails to answer the VoIP voice call dialed by the contact terminal over time, the central device can collect the voice capability parameters of each terminal in the local area network, and determine the answering terminal (for example, terminal 2) from each terminal in the local area network, The voice data packets of the VoIP voice call are forwarded to the receiving terminal (for example, terminal 2).
