technical field

The present application relates to the field of communication technologies, and in particular to a network call transfer method and terminal.

Background technique

Internet calls (including audio calls, video calls) have become frequently used software in people's daily life and work. For this reason, more and more terminals in home networks or work networks are equipped with Internet call software. Moreover, the flexible transfer of network calls between different terminals has become a research hotspot among manufacturers.

Contents of the invention

A network call transfer method and terminal provided by the present application can implement network call transfer on different terminals, improve the flexibility of users to answer network calls, and meet user needs in different scenarios.

In order to achieve the above purpose, the embodiment of the present application provides the following technical solutions:

The first aspect provides a network call transfer system, including a first terminal, a second terminal, a third terminal, a first server, and a second server; the first terminal and the second terminal establish a signaling channel through the first server; A terminal and the second terminal establish a media channel through the second server; the second terminal is used to receive a first instruction from the user, and the first instruction is used to instruct transfer of the network call between the first terminal and the second terminal; the second terminal also In response to the first indication, send a first message to the first server through the signaling channel, the first message is used to request to transfer the network call of the second terminal to the third terminal; the first server is used to transmit the first message according to the first message , sending a second message to the third terminal, the second message is used to request to transfer the network call of the second terminal to the third terminal, and the second message includes the identifier of the media channel; the third terminal is used to send the second message according to the second message includes The identifier of the media channel is added to the media channel through the second server; the third terminal is used to exchange video data and/or audio data with the first terminal through the media channel.

It can be seen that since the transferred device (that is, the third terminal) can directly join the media channel originally created in this network call (that is, the media channel established by the first terminal and the second terminal through the second server), thereby realizing the third The real-time communication between the terminal and the first terminal is to transfer the network call on the second terminal to the third terminal for answering. Compared with the prior art, both parties in the call need to exit the current media channel and apply for a new media channel, and the transferred device joins the new media channel, so as to realize the transfer of the network call. The technical solution provided by the embodiment of the present application simplifies The flow of signaling interaction between the terminal (including the third terminal and the first terminal) and the server (including the first server and the second server) during the whole transfer process improves the transfer efficiency of the network call.

In a possible implementation, after the second terminal receives the call request from the first terminal and the network call with the first terminal is not connected, the second terminal receives the first indication; or, the second terminal receives the After receiving a call request from the first terminal, and the network call with the first terminal has been connected, the second terminal receives the first indication; or, after the second terminal sends a call request to the first terminal, and the first terminal does not When the network call with the second terminal is connected, the second terminal receives the first indication; or, after the second terminal sends a call request to the first terminal, and the first terminal has connected the network call with the second terminal, The second terminal receives the first indication.

That is to say, the user can transfer the current network call when the network call is not connected. The user can also transfer the current network call after connecting to the network call. The called party can transfer the Internet call to other devices, and the calling party can also transfer the Internet call to other devices. It can be seen that the technical solutions provided by the embodiments of the present application can realize the flexible transfer of network calls by users, and meet the needs of users for network calls in different scenarios.

In a possible implementation manner, the third terminal is further configured to output a first prompt after receiving the second message, and the first prompt is used to ask whether the user agrees to accept the network call transferred by the second terminal; the third terminal Joining the media channel through the second server according to the identifier of the media channel includes: in response to the third terminal receiving the second indication, the third terminal joins the media channel through the second server according to the identifier of the media channel, wherein the second indication is used for Indicates that the user agrees to accept the network call transferred by the second terminal. Thereby, a way of asking the user of the third terminal whether to accept the transfer is provided.

In some other examples, if the second terminal transfers the network call to the third terminal for the first time, the third terminal may output the first prompt to ask the user whether to agree to accept the network call transferred from the second terminal. After the user chooses to agree to accept the network call transferred from the second terminal this time, when the second terminal transfers the network call to the third terminal again, the third terminal can default that the user has agreed to transfer the network call, and directly display the relevant information of the network call. interface (the call interface of the Internet call or the Internet call interface). In some other examples, the user of the third terminal may also pre-authorize receiving the network call transferred from the second terminal. For example, the user enables the network call transferred by the second terminal in advance in the network call application or system settings. Then, no matter whether it is the first time or the Mth time (M is greater than 1) that the third terminal receives the network call transferred by the second terminal, it does not need to output the above-mentioned first prompt, and directly displays the relevant interface of the network call.

In a possible implementation manner, the second server is further configured to send a third message to the first terminal and the second terminal, where the third message is used to trigger the third terminal to join the media channel; the second The terminal is further configured to exit the media channel through the second server after receiving the third message.

It can be understood that if the second terminal withdraws from the media channel, the second terminal will not be able to receive the media data exchanged between the first terminal and the third terminal. In some other examples, the second terminal may not exit the media channel, so the second terminal can still receive the media data exchanged between the first terminal and the third terminal.

In a possible implementation manner, the third terminal is further configured to receive a third instruction from the user, where the third instruction is used to instruct to transfer the network call on the third terminal to the second terminal; in response to receiving the third Instructing to send a fourth message to the first server, the fourth message is used to request to transfer the network call on the third terminal to the second terminal; the first server is also used to send a fifth message to the second terminal, the fifth message It is used to notify that the network call on the third terminal is transferred to the second terminal; the second terminal is also used to join the media channel through the second server according to the fifth message; exchange video data and/or interact with the first terminal through the media channel audio data.

That is to say, the user can operate on the third terminal to instruct to transfer the current network call back to the original second terminal, thereby providing a richer and more flexible network call transfer solution.

In a possible implementation manner, the second terminal is further configured to receive a fourth instruction from the user, where the fourth instruction is used to instruct to transfer the network call on the third terminal to the second terminal; in response to receiving the fourth indicating that the second terminal sends a sixth message to the first server, the sixth message is used to request to transfer the network call on the third terminal to the second terminal; the first server is also used to send a seventh message to the second terminal, The seventh message is used to notify that the network call on the third terminal is transferred to the second terminal; the second terminal is also used to join the media channel through the second server according to the seventh message; and interact video with the first terminal through the media channel data and/or audio data.

That is to say, the second terminal still retains part of the control authority over the network call. For example, the user can operate on the second terminal to instruct to transfer the network call made on the third terminal to the second terminal, thereby providing a richer and more flexible network call transfer solution.

In a possible implementation manner, the second terminal is further configured to disconnect the signaling channel with the first server after receiving the third message.

It can be understood that after the second terminal disconnects the signaling channel, the second terminal completely exits the current network call and no longer controls the current network call. In other examples, the mobile phone can still reserve the signaling channel. When the user continues to perform related control operations on the second terminal, such as switching back to the network call, ending the network call, etc., the second terminal can forward the related control signaling through the signaling channel to execute the related control process.

In a possible implementation, the second terminal and the third terminal log in to the same account; or, the second terminal and the third terminal respectively log in to different accounts belonging to the same group; or, the second terminal and the three terminals are located in the same communication in the network.

In a specific embodiment, after receiving the user's instruction to transfer the network call, the second terminal can use the wireless communication function (such as Wi-Fi or Bluetooth, etc.) to search for surrounding devices, that is, the user can transfer the second terminal The network call on the device is transferred to other devices near the second terminal. In this way, the user can flexibly choose the most suitable device nearby to answer the current network call. For example, users can transfer Internet calls on their mobile phones to the smart screen, enjoy a larger video experience on the smart screen, and free the user's hands. In some other scenarios, after the network call is transferred to the smart screen, more family members or colleagues can be invited to participate in the network call. Alternatively, the user can also transfer the network call on the smart screen to the mobile phone, which is convenient for protecting the user's privacy, or for the user to move the location. For another example, the user can transfer the Internet call on the mobile phone to the vehicle-mounted terminal, freeing the user's hands and making it easier for the user to drive. Or, the user can also transfer the Internet call on the vehicle terminal to the mobile phone, so that the user can continue to answer the Internet call when leaving the vehicle.

In another specific embodiment, after the second terminal receives the user's instruction to transfer the network call, the second terminal may also access the home server to inquire about the associated device of the second terminal. Wherein, the associated device of the second terminal refers to a device that is logged in with the same account as the second terminal, or the account logged in by the device and the account logged in by the second terminal belong to the same family group. It should be noted that the associated device of the second terminal queried by the home server may not be located near the second terminal. In other words, the method provided by the embodiment of the present application can also be applied to transfer the network calling function on the second terminal to other remote devices. In this way, the user can choose to transfer the current network call to other more suitable users in the family or work environment to answer the call. For example, when the user goes out, the Internet call on the mobile phone can be transferred to the smart screen at home, and the family member can answer the Internet call.

The second aspect provides a method for transferring an Internet call, which is applied to a third terminal. During the second terminal transferring the Internet call between the second terminal and the first terminal to the third terminal, the second terminal and the first terminal pass through the second terminal.

Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

Fig. 1 shows a network call system provided by an embodiment of the present application. As shown in FIG. 1 , the network communication system includes two or more terminals (for example, terminal 100 and terminal 200 ), a signaling server 300 and a media server 400 . Wherein, each of the above-mentioned terminals can establish a communication connection with the signaling server 300 through one or more networks, and establish a communication connection with the media server 400 through one or more networks.

In the embodiment of the present application, the terminal 100 can establish a call link with the terminal 200 through the signaling server 300 and the media server 400, so as to realize the network call service between the terminal 100 and the terminal 200. The network call service provided by the embodiment of the present application can be applied to scenarios such as audio calls, video calls, video conferences, live video broadcasts, online classrooms, and Internet medical care.

Wherein, the signaling server 300 is configured to establish a signaling channel between the terminal 100 and the terminal 200 . The terminal 100 and the terminal 200 exchange control-related messages in the network call service through the signaling channel, such as establishing a call link, disconnecting a call link, transferring a call, and the like.

Wherein, the media server 400 is configured to establish a media channel between the terminal 100 and the terminal 200 . The terminal 100 and the terminal 200 exchange media data through the media channel, where the media data includes video data, audio data, and the like.

As users own or use more and more terminals, there is often a need to transfer network calls. Further, the network calling system described in FIG. 1 further includes a terminal 500 . The terminal 500 respectively establishes communication connections with the signaling server 300 and the media server 400 through one or more networks. For example, when user A of terminal 100 and user B of terminal 200 are in an internet call, user B may transfer the internet call on terminal 200 to terminal 500 for answering. Optionally, the terminal 500 and the terminal 200 log into the same user account, or log into different accounts belonging to the same group (such as a family group). Of course, it may also be that user A migrates the network call on terminal 100 to another terminal of user A, which is not limited in this application.

In one technical solution, user B may operate terminal 200 to instruct terminal 200 to transfer the network call on terminal 200 to terminal 500 . On the one hand, the terminal 200 informs the terminal 100 through the signaling server 300 that the terminal 200 will transfer the network call to the terminal 500 . Then, the terminal 100 exits the current media channel (denoted as media channel 1) through the media server 400 . Moreover, the terminal 100 creates a new media channel (denoted as media channel 2) through the media server 400, and joins the media channel 2. The terminal 100 notifies the terminal 500 of the newly created media channel 2 through the signaling server 300 . On the other hand, the terminal 200 exits the current media channel 1 through the media server 400 and joins the media channel 2 . So far, terminal 100 and terminal 500 have established a new media channel for transmitting media data, that is, user B can continue the network call with user A through terminal 500 .

It can be noticed that during the process of user B migrating the network call on the terminal 200 to the terminal 500, the signaling between the terminal (including the terminal 100, the terminal 200 and the terminal 500) and the server (including the signaling server 300 and the media server 400) The interaction is cumbersome, and the transfer process of the network call takes a long time.

In some other scenarios, the terminal 100 can also establish a communication link with two or more other terminals (such as the terminal 200 and the terminal 600) through the signaling server 300 and the media server 400, so as to realize network calls between two or more people. (Including many-to-one, one-to-many, many-to-many network calls, etc.). Among them, the terminal 100, the terminal 200 and the terminal 600 all join the media channel 1 that the terminal 100 applies to the media server 400 to create for this network call. It can be understood that if the above technical solution is still adopted to migrate the network call of a certain terminal (such as terminal 200) to another terminal (such as terminal 500), terminal 200 needs to notify more terminals (terminal 100 and terminal 600) to quit Current media channel 1. Moreover, after the terminal 100 creates the new media channel 2, it needs to notify more terminals (terminal 200 and terminal 600) to join the current media channel 2. It can be seen that the signaling interaction between the terminal (including the terminal 100, the terminal 200, the terminal 500, and the terminal 600) and the server (including the signaling server 300 and the media server 400) is more cumbersome, and the transfer process of the network call takes more time. long.

For this reason, the embodiment of the present application provides another technical solution. The transferred terminal (i.e. terminal 500) multiplexes the previous media channel 1, thereby simplifying the signaling interaction between the terminal and the server during the network call migration process, reducing The time-consuming transfer process enables users to flexibly transfer network calls between different terminals. In addition, in the embodiment of the present application, the user can also migrate the network call back to the original terminal (ie, the terminal 200 ), and at this time, the media channel 1 is also directly multiplexed. It can be seen that the signaling interaction between the terminal and the server during the migration process of the network call is simplified, the time consumption of the migration process is reduced, and the user can flexibly migrate the network call between different terminals.

Hereinafter, taking terminal 100 as mobile phone 1, terminal 200 as mobile phone 2, and terminal 500 as a smart screen as examples, the technical solution provided by the embodiment of the present application will be described in detail with reference to the accompanying drawings.

First, the mobile phone 1 calls the mobile phone 2 through an Internet calling application (for example, Unified Call). Wherein, the Internet calling application is an application including an Internet calling function. For example, the web calling application can be a calling application or a contacts application. That is, the calling application or the contact application is integrated with an Internet calling function.

Exemplarily, take "Smooth Call" in the call application as an example. As shown in (1) in FIG. 4 , it is the desktop 501 displayed on the mobile phone 1 . In response to detecting that user A operates the "Phone" application icon 502, the mobile phone displays the main interface 503 of the "Phone" application as shown in (2) in FIG. 4 . In response to detecting that user A operates the icon 504 of "Contact Call" in the main interface 503 of the "Phone" application, the mobile phone displays an interface 505 of "Contact Call" as shown in (1) in FIG. main interface of call function). The interface 505 includes an input box 506, local information 507, and contact information 508 for enabling the network call function. User A can enter a keyword in the input box 506 to search for a contact, or enter a number to directly make an Internet call. User A can also search for the desired contact in the contact information 508, and call the contact through the "voice" control or "video" control corresponding to the contact. For example, user A operates the "Video" control 509 corresponding to Jane, and the mobile phone 1 sends a call request for a video call to the signaling server through the network for requesting a video call with Jane. Wherein, the call request carries Jane's mobile phone number. At the same time, the mobile phone 1 displays a video call interface 510 as shown in (2) in FIG. 5 . Exemplarily, the video call interface 510 may include information such as the avatar of the called party, a mobile phone number (not shown in the figure), and a name (not shown in the figure). The video call interface 510 also includes a hang up control for ending the currently ongoing video call. Optionally, the video call interface 510 may also include a control for switching a video call to a voice call, a control for turning on a speaker, etc. (none of which are shown in the figure).

After receiving the call request sent by the signaling server, the mobile phone 2 displays a video call interface 601 as shown in (1) in FIG. 6A. In this video call interface 601, information such as the avatar, mobile phone number (not shown in the figure) and name (not shown in the figure) of the calling party can be displayed. "Control 602. Among them, the "discovery" control 602 can be used to search for devices around the mobile phone 2 . Of course, the name of the "discovery" control 602 here may also be expressed as other words such as "scan", "search", etc., which is not limited in this embodiment of the present application.

It should be noted that, when the mobile phone 1 calls the mobile phone 2, the mobile phone 1 and the mobile phone 2 respectively establish a signaling channel with the signaling server and a media channel with the media server. It should be noted that, in the embodiment of this application, even if mobile phone 2 transfers the network call to other devices, or mobile phone 1 transfers the network call to other devices, the transferred device and the peer device are still multiplexed. The media channel exchanges media data.

In some embodiments, in response to detecting that user B operates the "discovery" control 602 in the video call interface 601 shown in (1) in FIG. The surrounding devices are searched, and an interface 603 as shown in (2) in FIG. 6A is displayed. The above-mentioned interface 603 may include a search list 604, and the information list of the surrounding devices searched by the mobile phone 2 is displayed in the search list 604. , Laptop (eg named MateBook X). That is to say, user B can transfer the network call on the mobile phone 2 to other devices near the mobile phone 2 . In this way, the user can flexibly choose the most suitable device nearby to answer the current network call. For example, users can transfer Internet calls on their mobile phones to the smart screen, enjoy a larger video experience on the smart screen, and free the user's hands. In some other scenarios, after the network call is transferred to the smart screen, more family members or colleagues can be invited to participate in the network call. For another example, the user can transfer the Internet call on the mobile phone to the vehicle-mounted terminal, freeing the user's hands and making it easier for the user to drive.

Optionally, as a specific example, the devices displayed in the search list 604 are devices near the mobile phone 2 . Moreover, the device and the mobile phone 2 log in with the same account, or the account logged in by the device and the account logged in by the mobile phone 2 belong to the same group (such as a family group), or the device and the mobile phone 2 belong to the same communication network (such as the same a Wi-Fi network). Optionally, as another specific example, the devices displayed in the search list 604 are devices capable of transferring network calls. That is to say, the mobile phone 2 screens out devices that support the ability to transfer network calls from the searched devices. Wherein, the device capable of transferring Internet calls is, for example, a device installed with an Internet call application, and the Internet call application supports the function of transferring Internet calls.

In some other embodiments, in response to detecting that user B operates the "discovery" control 602 in the video call interface 601 shown in (1) in FIG. Wherein, the associated device of the mobile phone 2 refers to a device that is registered with the same account as the mobile phone 2, or the account registered with the device and the account registered with the mobile phone 2 belong to the same family group. Then, the mobile phone 2 displays an interface 603 as shown in (2) in FIG. 6A. The above-mentioned interface 603 may include a search list 604, and the search list 604 displays an information list of associated devices inquired by the mobile phone 2, such as a smart screen (such as Vision), a smart speaker (such as SoundX), a notebook computer (such as named MateBook X). It should be noted that the associated device of the mobile phone 2 queried through the home server may not be located near the mobile phone 2 . In other words, the method provided by the embodiment of the present application can also be applied to transfer the Internet call function on the mobile phone 2 to other remote devices. In this way, the user can choose to transfer the current network call to other more suitable users in the family or work environment to answer the call. For example, when the user goes out, the Internet call on the mobile phone can be transferred to the smart screen at home, and the family member can answer the Internet call.

Optionally, as a specific example, the devices displayed on the search list 604 are currently online devices. Optionally, as another specific example, the devices displayed in the search list 604 are devices capable of transferring network calls. That is to say, the mobile phone 2 screens out devices that support the ability to transfer network calls from the queried associated devices.

In the search list 604 of the above-mentioned interface 603, there is a "transfer call" control corresponding to each device. The "transfer call" control can be used to switch the current network call of the mobile phone 2 to the corresponding device for answering. Of course, "transferring a call" herein may also be expressed as "transferring a call", "switching a call" and other words, which is not limited in this embodiment of the present application.

For example, if it is detected that user B operates the "transfer call" control 605 corresponding to the smart screen (Vision), mobile phone 2 sends user B's transfer instruction to the signaling server, instructing to transfer the network call on mobile phone 2 to the smart screen. The signaling server records the corresponding relationship between the mobile phone 2 and the smart screen in this network call according to the received transfer instruction. That is, the mobile phone 2 and the smart screen are marked as the same participant in this network call. It should be noted that, in fact, the users of the mobile phone 2 and the smart screen may or may not be the same user. In other words, after the network call is transferred, the user B of the mobile phone 2 can continue to answer it, or other users can continue to answer it. Then, the signaling server broadcasts a transfer request, and the transfer request carries the information of the media channel where the mobile phone 1 and the mobile phone 2 are located. In this way, all devices added to the media channel can receive the transfer request and know that the mobile phone 2 and the smart screen correspond to the same participant. In addition, the signaling server sends a transfer request to the smart screen, and the smart screen obtains the information of the media channel where the mobile phone 1 and the mobile phone 2 are located.

It should be noted that the control for triggering the mobile phone 2 to transfer the call can also be set on other interfaces. For example, in the video call interface 606 shown in (1) in FIG. 6B, a "transfer call" control 607 may also be set. In response to detecting that user B operates the "transfer call" control 607, the mobile phone 2 displays an interface 608 as described in (2) in FIG. 6B. The interface 608 displays a list 609 of surrounding devices searched by the mobile phone 2 . User B can select a target device for transferring the call in the device list 609 . Of course, user B can also use other methods to trigger the mobile phone 2 to transfer the network call function. Trigger mobile phone 2 to transfer the current network call.

After the smart screen receives the transfer request sent by the signaling server, it outputs prompt information to prompt the user (it can be user B or other users) to choose whether to agree to answer the transferred network call on the device. In some examples, after the smart screen receives the transfer request sent by the signaling server, it can display an interface 701 as shown in (1) in FIG. interface) to display a prompt box 702, prompting the user "whether to agree to receive the network call transfer request from Phone P40". Optionally, the smart screen can further prompt the user, and if they agree, click the "OK" button on the remote control. If you do not agree, click the "Cancel" button on the remote control. In other examples, after receiving the transfer request sent by the signaling server, the smart screen may also display an interface 704 as shown in FIG. Whether the user agrees to receive network call transfer requests from Phone P40. Alternatively, the smart screen plays voice prompts, etc. In short, the embodiment of the present application does not limit the prompting manner of the smart screen.

When the user clicks the "OK" button on the remote control or enters voice commands such as "Yes" (or "Agree"), the smart screen displays a video call interface 703 as shown in (2) in FIG. 7A . Further, the user can answer or hang up the Internet call on the interface 703 . It should be noted that when it is detected that the user clicks the "OK" button on the remote control or enters voice commands such as "yes" (or "agree"), the smart screen also requests to join the media channel through the media server, so as to realize the establishment of a smart screen. The media channel for communication between the screen and mobile phone 1. At this point, the smart screen displays a video call interface 706 as shown in FIG. 7B . Wherein, the video call interface 706 displays the video images captured by the mobile phone 1 received through the above-mentioned media channels, and the video images collected by the smart screen itself. The smart screen can also output the audio data collected by the mobile phone 1 received through the above-mentioned media channel. The video images and audio data collected by the smart screen will also be sent to the mobile phone 1 through the media channel, so as to realize the real-time communication between the smart screen and the mobile phone 1 . As shown in FIG. 7B , the video call interface 706 can also control the controls of the network call, for example, including a "hang up" control, a "mute" control, and the like. Optionally, the video call interface 706 may also include a "return to original device" control 707, which is used to transfer the current network call back to the mobile phone 2 again. Optionally, the video call interface 706 may also include a "discovery" control (not shown in the figure), which is used to transfer the current network call to another device again. Among them, the process of migrating back to the original device and transferring to another device is similar to the process of migrating to the smart screen, so this article will not repeat them.

When user B decides to transfer the network call on the smart screen, the smart screen can notify the mobile phone 2 through the signaling server, or notify the mobile phone 2 through the wireless connection between the smart screen and the mobile phone 2, or notify the mobile phone 2 through the home server . In some embodiments, when the mobile phone 2 learns that user B agrees to transfer the network call, the mobile phone 2 can turn off the screen, or display the desktop, or display the interface before starting the network call function, or output a prompt message to remind user B that the current network call has been transferred. The network call is transferred to the smart screen. For example, the mobile phone 2 displays an interface 801 as shown in FIG. 8 . Wherein, the interface 801 includes a prompt box 802 for prompting user B that the current network call has been transferred to the smart screen.

Optionally, after the mobile phone 2 transfers the network call to other devices, the mobile phone 2 may retain part of the control authority for the network call. For example, the interface 801 also includes a "return call" control 803, which is used to transfer the network call transferred from the local machine back to the local machine for answering. The interface 801 may also include an "end call" control 804 for hanging up the current network call. The interface 801 includes a close control 805 for closing the prompt box 802 . That is to say, after the mobile phone 2 transfers the network call to other devices, the user B can continue to use other functions of the mobile phone 2 .

It should be noted that after the mobile phone 2 transfers the network call to the smart screen, the mobile phone 2 can request to exit the media channel through the media server. That is, the mobile phone 2 no longer receives the media data (audio data, video data) collected by the mobile phone 1 and the smart screen. Of course, the mobile phone 2 may not exit the media channel, that is, the mobile phone 2 can continue to receive the media data collected by the mobile phone 1 and the smart screen. In some examples, the mobile phone 2 may also disconnect the signaling channel with the signaling server, that is, the mobile phone 2 completely exits the current network call, and no longer controls the current network call. In some other examples, the mobile phone can still reserve the signaling channel with the signaling server. When user B continues to perform related control operations on the mobile phone 2, such as switching back to the network call, ending the network call, etc., the mobile phone 2 can execute the relevant control process through the signaling channel between the signaling servers.

The above embodiments have described the process that the called party (namely the mobile phone 2 ) transfers the network call to other devices when receiving an incoming call of the network call. In some other embodiments, when the calling party (namely mobile phone 1 ) calls the called party (ie mobile phone 2 ), the calling party may also transfer the network call to other devices. For example, as shown in FIG. 9 , the video call interface 901 displayed on mobile phone 1 to call mobile phone 2 also includes a "discovery" control 902, which can be used to search for devices around mobile phone 1, so that user A can make a network call on mobile phone 1. Move to another device. For the specific transfer process, please refer to the process of user B transferring the network call on the mobile phone 2 to the smart screen, which will not be repeated here.

The above has explained in detail that when the called party receives an incoming call of the network call and does not answer the network call, that is, when the current network call is not connected yet, the called party (or calling party) will transfer the network call to another the entire process on the device. In some other embodiments, after the called party answers the network call, that is, after the network call is connected, the called party or the calling party may also transfer the network call to other devices. Here still take the called party to transfer the network call to the smart screen as an example for illustration.

For example, as shown in (1) in Figure 10, it is the video call interface 1001 displayed after the mobile phone 2 connects to the video call, and the video picture collected by the mobile phone 2 is displayed in the video call interface 1001, and the mobile phone 1 receives the video through the media channel. Captured video footage. At the same time, the mobile phone 2 also plays the audio data collected by the mobile phone 1 received through the media channel. Among them, the video images and audio data collected by the mobile phone 2 will also be sent to the mobile phone 1 through the media channel, so as to realize the real-time communication between the mobile phone 1 and the mobile phone 2 . The video call interface 1001 also includes some network call control controls, such as hang up control and “discovery” control 1002 . Similar to the process of transferring the Internet call when user B receives an incoming call, user B can use the "discovery" control 1002 to trigger the mobile phone 2 to search for surrounding devices and transfer the current Internet call to the device selected by the user. For example, in response to user B operating the "discovery" control 1002, the mobile phone 2 displays an interface 1003 as shown in (2) in FIG. Further, in response to the user operating the "transfer call" control 1005 corresponding to the smart screen, the mobile phone 2 sends a transfer instruction to the signaling server, instructing to transfer the network call on the mobile phone 2 to the smart screen. The signaling server records the corresponding relationship between the mobile phone 2 and the smart screen in this network call according to the received transfer instruction. Then, the signaling server broadcasts a transfer request, and the transfer request carries the information of the media channel. In this way, all devices added to the media channel can receive the transfer request and know that the mobile phone 2 and the smart screen correspond to the same participant. In addition, the signaling server sends a transfer request to the smart screen, and the smart screen obtains the information of the media channel where the mobile phone 1 and the mobile phone 2 are located. It can be understood that the control for triggering mobile phone 2 to transfer the network call can also be set on other interfaces, or user B can also use other methods to trigger mobile phone 2 to transfer the network call.

In addition, after receiving the instruction from the mobile phone 2 to transfer the video call, the smart screen may display an interface 701 as shown in (1) in FIG. 7A , or display an interface 704 as shown in FIG. 7C . After receiving the user's consent to transfer the video call, the smart screen displays a video call interface 706 as shown in FIG. 7B . For other content, please refer to the relevant content above, and will not repeat them here.

In addition, the process of triggering the transfer of the network call by the calling party is similar to the process of triggering the transfer of the network call by the called party, and will not be repeated here.

The above takes the one-to-one Internet call between mobile phone 1 and mobile phone 2 as an example to illustrate the overall process of transferring the Internet call by the calling party or the called party. In fact, the method provided by the embodiment of the present application is also applicable to one-to-many Internet calls, many-to-one Internet calls, and many-to-many Internet calls where any party transfers the Internet calls on the machine to other devices.

The following describes in detail the message interaction process between various devices during the network call transfer process in different scenarios.

As shown in FIG. 11 , it is a schematic flowchart of a method for transferring network calls provided by the embodiment of the present application. The method can be applied to one-to-one network calls. The method includes:

S1100. Mobile phone 1 receives an instruction to call mobile phone 2 .

The mobile phone 1 can call the mobile phone 2 through the network call application (for example, the free call). For example, when mobile phone 1 receives an instruction to call mobile phone 2, it may be that mobile phone 1 detects that the user (for example, specifically user A) operates the "video" control 509 corresponding to Jane in the interface 505 shown in (1) in FIG. 5 .

S1101a, the mobile phone 1 establishes a signaling channel with the mobile phone 2 through the signaling server.

S1101b. The mobile phone 1 establishes a media channel with the mobile phone 2 through the media server.

In step S1101a and step S1101b, mobile phone 1 establishes a signaling channel with mobile phone 2 through a signaling server and a media channel with mobile phone 2 through a media server based on the real-time communication protocol according to the instruction of calling mobile phone 2 . It should be noted that steps S1101a and S1101b are shown in FIG. 11, which are only used to illustrate that the process of establishing a call connection between mobile phone 1 and mobile phone 2 includes two steps of establishing a signaling channel and a media channel, and does not limit steps S1101a and S1101a. S1101b is two mutually independent steps. In some examples, the process of performing step S1101a includes performing the process of step S1101b. That is to say, first execute part of the process in step S1101a, then execute step S1101b, and then continue to execute other processes in step S1101a. It should be noted that, when the mobile phone 1 establishes a signaling channel with the mobile phone 2 through the signaling server, the signaling server obtains the information of the media channel, such as the identifier of the media channel.

S1102. The mobile phone 2 displays a first calling interface.

After the mobile phone 2 receives the call request sent by the mobile phone 1 through the signaling server, it displays the first call interface.

For example, the mobile phone 2 may display a video call interface 601 as shown in (1) in FIG. 6A. In the video call interface 601 , information such as the avatar of the caller, mobile phone number and the like may be displayed, and a “refusal” control, a “answer” control and a “discovery” control 602 may also be displayed. Among them, the "discovery" control 602 can be used to search for devices around the mobile phone 2 .

S1103. The mobile phone 2 receives a transfer instruction for instructing to transfer the network call on the mobile phone 2 to the smart screen for answering.

In some embodiments, the user of the mobile phone 2 (for example, user B in particular) can instruct to switch the network call on the mobile phone 2 to the smart screen to answer when receiving an incoming call and the network call is not connected. That is to say, when user B receives an incoming call on mobile phone 2, the incoming call can be transferred to other devices, and the network call with user A can be connected on other devices.

For example, in response to detecting that user B operates the "discovery" control 602 in the video call interface 601 shown in (1) in FIG. , or visit the home server to inquire about the associated devices of the mobile phone 2, and display an interface 603 as shown in (2) in FIG. 6A. This interface 603 may include a search list 604, and a list of transferable equipment information is displayed in the search list 604, such as a smart screen (named such as Vision), a smart speaker (named such as SoundX), a notebook computer (named such as MateBook X). If it is detected that user B operates the "transfer call" control 605 corresponding to the smart screen (Vision), it is considered that the mobile phone 2 has received the transfer instruction from user B and instructed to transfer the Internet call on the mobile phone 2 to the smart screen. In some examples of this embodiment, the smart screen may be located near the mobile phone 2, for example, both the mobile phone 2 and the smart screen are located at home or in an office. That is to say, the mobile phone 2 transfers the network call to other nearby devices for answering. In other examples of this embodiment, in the method that the mobile phone 2 queries the associated devices of the mobile phone 2 by accessing the home server, the smart screen may not be located near the mobile phone 2 . That is to say, the mobile phone 2 transfers the network call to other remote devices so that other users can answer the current network call.

In some other embodiments, user B may also instruct to switch the Internet call on the mobile phone 2 to the smart screen to answer it after connecting to the Internet call. That is to say, after user B connects to the Internet call on mobile phone 2, and during the Internet call with user A, he can transfer the Internet call to other devices, and continue the Internet call with user A on other devices.

For example, after user B connects to the network call, the mobile phone 2 displays a video call interface 1001 as shown in (1) in FIG. 10 . The screen of user A of mobile phone 1 and the screen of user B of mobile phone 2 are displayed on the video call interface 1001 . The video call interface 1001 also displays a "switch camera" control, a "hang up" control,

and a "Discovery" control 1002 . When it is detected that user B operates the "discovery" control 1002, the mobile phone 2 uses the wireless communication function (such as Wi-Fi or Bluetooth, etc.) to search for surrounding devices, and displays an interface 1003 as shown in (2) in FIG. 10 . The interface 1003 may include a search list 1004, and the search list 1004 displays information lists of surrounding devices searched by the mobile phone 2, for example, the mobile phone 2 searches for a smart screen (named, for example, Vision), a smart speaker (named, such as SoundX) , Laptop (named, for example, MateBook X). Among them, there is a "transfer call" control corresponding to each device found in the search. If it is detected that user B operates the "transfer call" control 1005 corresponding to the smart screen (Vision), it is considered that the mobile phone 2 has received the transfer instruction from user B, and instructed to transfer the Internet call on the mobile phone 2 to the smart screen. In some examples of this embodiment, the smart screen may be located near the mobile phone 2, for example, both the mobile phone 2 and the smart screen are located at home or in an office. That is to say, the mobile phone 2 transfers the network call to other nearby devices for answering. In other examples of this embodiment, in the method that the mobile phone 2 queries the associated devices of the mobile phone 2 by accessing the home server, the smart screen may not be located near the mobile phone 2 . That is to say, the mobile phone 2 transfers the network call to other remote devices so that other users can answer the current network call.

It should be noted that the transfer process is described below by taking the called party (ie, the mobile phone 2 ) as an example to transfer the network call to another device (smart screen). In some other embodiments, after user B connects to the network call, user A can also operate on mobile phone 1 to instruct mobile phone 1 to transfer the current network call to other devices of user A. The transfer process is similar to the process in which user B transfers the Internet call on mobile phone 2 to the smart screen, and will not be described separately.

S1104. The mobile phone 2 sends a transfer notification to the signaling server, and the transfer notification carries the identifier of the smart screen.

After receiving the transfer instruction from user B, mobile phone 2 sends a transfer notification to the signaling server, notifying that the network call on mobile phone 2 is transferred to the smart screen. Wherein, the identification of the smart screen may be, for example, the MAC address of the smart screen, or the ID (also called international mobile equipment identity (IMEI) or serial number, etc.) of the smart screen.

S1105. The signaling server records the corresponding relationship between the mobile phone 2 and the smart screen during the network call.

Specifically, the signaling server establishes a corresponding relationship between the identification of the smart screen and the identification of the mobile phone 2 . That is to say, in this network call, the smart screen and the mobile phone 2 correspond to a participant. It should be noted that, in fact, the users of the mobile phone 2 and the smart screen may or may not be the same user. In other words, after the network call is transferred, the user B of the mobile phone 2 can continue to answer it, or other users can continue to answer it. Wherein, the identification of the mobile phone 2 includes a mobile phone number, a MAC address, an ID, a login account, and the like.

S1106. The signaling server broadcasts a transfer request, which is used to notify other devices in the media channel that the mobile phone 2 will transfer the network call to the smart screen. And, the signaling server sends a transfer request to the smart screen.

S1107. The smart screen displays a transfer interface.

For example, the smart screen displays an interface 701 as described in (1) in FIG. 7A , and the interface 701 includes prompt information 702 for asking whether the current user of the smart screen agrees to accept the network call transfer request from the mobile phone 2 . Alternatively, the smart screen displays an interface 704 as shown in FIG. 7C , and the interface 704 includes prompt information 705 . Alternatively, the smart screen may also ask the current user whether to agree to accept the transfer request of the network call from the mobile phone 2 by playing a voice prompt message.

It should be noted that if the mobile phone 2 transfers the network call to the smart screen for the first time, the smart screen can display the above-mentioned transfer interface to ask the user whether to agree to accept the network call transferred from the mobile phone 2. After the user chooses to accept the network call transferred from the mobile phone 2 this time, when the mobile phone 2 transfers the network call to the smart screen again, the smart screen can default that the user has agreed to transfer the network call, and the smart screen can directly display the relevant interface of the network call (the call interface of the Internet call or the Internet call interface). That is, the smart screen directly executes step S1112. In some other embodiments, the user of the smart screen may also pre-authorize receiving the network call transferred from the mobile phone 2 . For example, the user enables to receive the network call transferred by the mobile phone 2 in advance in the network call application or system settings. In this way, when the smart screen receives the network call transferred by the mobile phone 2, it directly executes step S1112.

It should also be noted that if the mobile phone 2 transfers the network call when it receives an incoming call but is not connected to the network call, the smart screen can ring to remind the user that there is an incoming call. Moreover, the smart screen also returns a ringing notification to the signaling server, mobile phone 1 and mobile phone 2, that is, step S1108 is performed. If the mobile phone 2 transfers the network call after the user connects to the network call, the smart screen does not need to ring at this time, that is, step S1108 does not need to be performed.

S1108. The smart screen sends a ringing notification to the mobile phone 1 and the mobile phone 2 through the signaling server. Correspondingly, mobile phone 1 and mobile phone 2 receive a ringing notification from the smart screen.

This step is optional. If the mobile phone 2 transfers the network call after the user connects to the network call, the smart screen does not need to ring at this time, and step S1108 does not need to be performed.

S1109. The smart screen receives an instruction of agreeing to transfer.

Exemplarily, the user of the smart screen, such as user B or other users, can operate on the remote control of the smart screen, for example, click the "OK" button to instruct the smart screen to receive the network call from the mobile phone 2 transfer request. Alternatively, the user of the smart screen can also input a voice command of "agree" (or "yes", "agree to transfer", etc.), instructing the smart screen to receive the transfer request of the network call from the mobile phone 2. Of course, the user of the smart screen can also reject the transfer request of the network call from the mobile phone 2 . If the user of the smart screen refuses, the transfer process of the network call ends. The mobile phone 2 continues to display the call interface or the conversation interface, that is, the mobile phone 2 continues to answer the network call.

S1110. The smart screen sends a message agreeing to transfer to the signaling server.

S1111. The signaling server broadcasts a message that the smart screen agrees to transfer. Correspondingly, mobile phone 1 and mobile phone 2 receive the message that the smart screen agrees to transfer.

S1112. The smart screen applies to the media server for joining the media channel according to the identifier of the media channel.

According to step S1104, it can be seen that the smart screen has obtained the identification of the media channel where the mobile phone 1 and the mobile phone 2 are located, and the smart screen can apply to the media server to join the media channel according to the identification of the media channel. In this way, the smart screen and the mobile phone 1 can realize the transmission of media data through the media channel. The media data includes video images and audio data collected by the mobile phone 1, and video images and audio data collected by the smart screen. That is to say, the video call between the smart screen and the mobile phone 1 is realized.

S1113. The media server broadcasts a notification that the smart screen has joined the media channel. Correspondingly, mobile phone 1 and mobile phone 2 receive a notification that the smart screen has joined the media channel.

S1114. The mobile phone 2 applies to the media server for exiting the media channel.

Exemplarily, the mobile phone 2 may apply for exiting the media channel after receiving the smart screen agreeing that the mobile phone 2 transfers the network call, that is, after performing step S1111. The mobile phone 2 may also apply for exiting the media channel after receiving the notification that the smart screen has joined the media channel, that is, after performing step S1113. It can be understood that if the mobile phone 2 exits the media channel, the mobile phone 2 will not be able to receive the media data of the interaction between the mobile phone 1 and the smart screen. In some other examples, the mobile phone 2 may not exit the media channel, that is, the mobile phone 2 may not execute step S1114. Then, the mobile phone 2 can still receive the media data of the interaction between the mobile phone 1 and the smart screen.

In some embodiments, the mobile phone 2 may also disconnect the signaling channel with the signaling server, that is, the mobile phone 2 completely exits the current network call and no longer controls the current network call. In some other examples, the mobile phone can still reserve the signaling channel with the signaling server. When user B continues to perform relevant control operations on the mobile phone 2, such as switching back to the network call, ending the network call, etc., the mobile phone 2 can forward the relevant control signaling through the signaling channel between the signaling servers to perform relevant control process.

S1115. The media server sends a notification to the mobile phone 1 that the mobile phone 2 has exited the media channel. Correspondingly, mobile phone 1 receives a notification that mobile phone 2 has exited the media channel.

If the mobile phone 2 does not execute step S1114, the media server does not need to execute step S1115.

S1116. The smart screen displays a second calling interface, and receives an answering instruction.

Exemplarily, after the smart screen receives the instruction that the user agrees to answer, the smart screen can automatically launch the application of the network call, and display the relevant interface of the network call.

For example, if the mobile phone 2 instructs to transfer the video call when it receives an incoming video call but the video call is not connected, the smart screen can display a video call interface 703 as shown in (2) in Figure 7A, the video call The interface 703 can be used to instruct the user (specifically user B, or other users) to answer the video call on the smart screen, or refuse to connect the video call.

For another example, if the mobile phone 2 instructs to transfer the video call when the video call is connected, the smart screen may display the video call interface 706 as shown in FIG. 7B .

S1117, the smart screen and the mobile phone 1 conduct a network call through the media channel of the media server.

The smart screen and the mobile phone 1 interact with each other through the media server to collect media data (such as video images, audio data, etc.), so as to realize real-time communication between the smart screen and the mobile phone 1 .

It can be seen from the above that in the technical solution provided by this application, since the transferred device (i.e., the smart screen) can directly join the media channel created by the mobile phone 1 to the media server for this network call, the real-time communication between the smart screen and the mobile phone 1 can be realized. communication. Compared with the mobile phone 1 that needs to exit the current media channel and apply for a new media channel, the smart screen adds a new media channel to realize the real-time communication transfer process between the smart screen and the mobile phone 1. The technical solution provided by the embodiment of the application simplifies the entire The process of signaling interaction between the device and the server during the transfer process improves the transfer efficiency of network calls.

In addition, in the technical solution provided by the embodiment of the present application, the user can transfer the current network call when the network call is not connected when the user just receives an incoming call of the network call. The user can also transfer the current network call after connecting to the network call. The called party can transfer the Internet call to other devices, and the calling party can also transfer the Internet call to other devices. It can be seen that the technical solutions provided by the embodiments of the present application can realize the flexible transfer of network calls by users, and meet the needs of users for network calls in different scenarios.

In addition, in the technical solution provided by the embodiment of the present application, the user can choose to transfer the network call to other nearby devices. In this way, the user can flexibly choose the most suitable device nearby to answer the current network call. For example, users can transfer Internet calls on their mobile phones to the smart screen, enjoy a larger video experience on the smart screen, and free the user's hands. In some other scenarios, after the network call is transferred to the smart screen, more family members or colleagues can be invited to participate in the network call. For another example, the user can also transfer the network call on the smart screen to the mobile phone for answering, so as to avoid leakage of user privacy. Users can also choose to transfer the current Internet call to a remote device. In this way, the user can select other more suitable users in the family or work environment to answer the call. For example, when the user goes out, the Internet call on the mobile phone can be transferred to the smart screen at home, and the family member can answer the Internet call.

In some other embodiments of the present application, after the mobile phone 2 transfers the network call to the smart screen, the mobile phone 2 or the smart screen can also transfer the network call back to the mobile phone 2 or transfer it to other devices according to the user's instructions. Wherein, the process of transferring the network call on the smart screen to other devices can refer to the method flow shown in FIG. 11 above, which will not be described again in this application.

As shown in FIG. 12 , it is a flow chart of a method for migrating back to the network call provided by the embodiment of the present application. The method includes: the above steps S1100 to S1117, and steps S1201 to S1207, specifically as follows:

S1201. The mobile phone 2 or the smart screen receives an instruction to switch back to the network call, and sends the switch back instruction to the signaling server.

In some embodiments, the user can operate on the smart screen to instruct to transfer the network call back to the original device. For example, the smart screen displays a video call interface 706 as shown in FIG. 7B , and the video call interface 706 includes a "return to original device" control 707 . When the smart screen detects that the user operates the "return to original device" control 707, the smart screen sends a relocation instruction to the signaling server. Alternatively, after the smart screen receives a voice command input by the user to migrate the network call back to the original device, the smart screen sends a migration instruction to the signaling server.

In other embodiments, when the mobile phone 2 still retains the control authority to control the current network call, the user can also instruct the mobile phone 2 to transfer the current network call back to the original device. For example, the mobile phone 2 displays an interface 801 as shown in FIG. 8 , and when the mobile phone 2 detects that the user operates the "return to call" control 803, the mobile phone 2 sends a return instruction to the signaling server. Alternatively, after the mobile phone 2 receives the voice command input by the user to transfer the network call back, the mobile phone 2 sends a transfer instruction to the signaling server.

It is understandable that "return call" can also be regarded as a special case of "transfer call", that is, transfer the network call to the original device.

S1202. The signaling server deletes the corresponding relationship between the mobile phone 2 and the smart screen in this network call.

S1203. The signaling server sends a relocation notification, which is used to notify that the network call is relocated to the mobile phone 2 .

S1204. After receiving the relocation notification, the mobile phone 2 applies to the media server for joining the media channel.

S1205. The media server broadcasts a notification that the mobile phone 2 joins the media channel.

S1206. The smart screen exits the media channel.

Exemplarily, the smart screen may exit the media channel when receiving the move-back notification, that is, after step S1203. Alternatively, the smart screen may exit the media channel after receiving the notification that the mobile phone 2 joins the media channel, that is, step A1205.

S1207, the mobile phone 2 and the mobile phone 1 conduct network calls through the media channel of the media server.

It can be seen that in the solution provided by the embodiment of this application, when the smart screen migrates the network call back to the mobile phone 2, the mobile phone 2 still reuses the original media channel, thereby realizing the restoration of the real-time communication between the mobile phone 2 and the mobile phone 1, which simplifies the migration process. The process of signaling interaction between the device and the server during the return process improves the return efficiency of network calls.

The above-mentioned transfer or migration process described in FIG. 11 and FIG. 12 is described by taking a one-to-one network call as an example. The technical solutions provided by the embodiments of the present application can be applied to multi-party network calls, and the multi-party network calls include one-to-many network calls, many-to-one network calls, and many-to-many network calls.

For example, the following takes terminal 100 as mobile phone 1, terminal 200 as mobile phone 2, terminal 500 as smart screen, terminal 600 as mobile phone 3 as an example, and mobile phone 1, mobile phone 2 and mobile phone 3 make multi-party network calls as an example to illustrate the transfer or The relocation process.

As shown in FIG. 13 , it is a flow chart of another method for transferring a network call provided by the embodiment of the present application. The method includes: step S1300 to step S1317 . Wherein, step S1300 to step S1317 respectively correspond to the contents of step S1100 to step S1117 in FIG. 11 . It should be noted that, the difference from the flow in FIG. 11 is that in the steps in FIG. 13 , when the mobile phone 1 establishes a signaling channel with the signaling server, the mobile phone 3 also establishes a signaling channel with the signaling server. When mobile phone 1 establishes a media channel with the media server, mobile phone 3 establishes a media channel with the media server. And the mobile phone 3 is also added to the media channel. In addition, when the signaling server or the media server notifies the mobile phone 1 of relevant information, it also notifies the mobile phone 3 at the same time. This difference is shown in each case by a filled black triangle in FIG. 13 . For other content from step S1300 to step S1317, please refer to the description of related content in step S1100 to step S1117 in FIG. 11 , which will not be repeated here.

As shown in FIG. 14 , it is a flow chart of another method for switching back to the network call provided by the embodiment of the present application. The method includes: step S1401 to step S1407 . Wherein, step S1401 to step S1407 respectively correspond to the contents of step S1201 to step S1207 in FIG. 12 . It should be noted that, the difference from the flow in FIG. 12 is that in the steps of FIG. 14 , when the signaling server or the media server notifies the mobile phone 1 of relevant information, it also notifies the mobile phone 3 at the same time. This difference is shown in each case by a filled black triangle in FIG. 14 . For other content from step S1401 to step S1407, please refer to the description of related content in step S1201 to step S1207 in FIG. 12 , which will not be repeated here.

It can be seen from the above that in the technical solution provided by the embodiment of the present application, the transferred device directly reuses the original media channel, and the original device does not need to exit the current media channel, nor does it need to add a new media channel, which greatly simplifies the entire transfer The process of signaling interaction between the device and the server improves the transfer efficiency of network calls. It is easy to understand that when there are more participants in the network call, compared with the solution that each participant in the network call needs to exit the current media channel and join a new media channel, the technical solution provided by the embodiment of the present application simplifies The more obvious the effect of the process, the higher the degree of improvement in transfer efficiency.

As another example, the interface circuit 1502 may be used to send signals to other devices (eg, a processor). Exemplarily, the interface circuit 1502 can read instructions stored in the memory, and send the instructions to the processor 1501 . When the instructions are executed by the processor 1501, the terminal or the server can be made to perform various steps performed by the terminal 100 or the terminal 200 or the terminal 500 or the signaling server 300 or the media server 400 in the above embodiments.
