[0023] The network in FIG. 2 is modified based on the networking architecture of the network in FIG. 1, mainly by modifying the communication service side and the terminal side. The content of the modification includes, but is not limited to, the content described below.

[0024] 1) Modify the VoNR+ media plane and the AI media component in FIG. 1 to obtain a media module. The media module supports translation and transcription, background blur, background replacement, icon replacement, and the ability to identify moving images.

[0028] 5) Modify the VoLTE SBC network element to add the data transmission Data Channel channel capability.

[0029] Based on the network composed of the VoLTE SBC network element for executing the video call control method in FIG. 1 above, and the network element for executing the video call control method in FIG. 2, the following proposes each embodiment of the video call control method of the present application for solving the problems in the above embodiments.

[0030] As shown in FIG. 3, FIG. 3 is a flowchart of a video call control method according to an embodiment of the present application. The video call control method of the embodiment of the present application is used in a voice over new radio platform and may include, but is not limited to, step S100, step S200, and step S300.

[0031] Step S100: Obtain the video call connection request and participant information of the first terminal sent from the call session control function unit.

[0032] In some embodiments, when the first terminal needs to perform Voice over New Radio (VoNR) communication with the second terminal, it sends a video call connection request to the base station unit. In this case, the base station unit forwards this video call connection request to the call session control function unit. The call session control function unit queries the subscriber information from the home subscriber user server based on this video call connection request, generates a video call connection request based on the video call connection request, and then the call session control function unit sends the video call connection request and subscriber information of the first terminal to the Voice over New Radio platform. At this time, the Voice over New Radio platform receives the video call connection request and subscriber information.

[0033] The first terminal may be the calling terminal or the called terminal, and it is not specifically limited in this embodiment. When the first terminal is the calling terminal, the second terminal is the called terminal, or when the first terminal is the called terminal, the second terminal is the calling terminal.

[0034] Step S200: Send the video call connection request to the avatar service unit and obtain the avatar image corresponding to the first terminal sent from the avatar service unit.

[0035] In some embodiments, the Voice over New Radio platform sends the video call connection request to the avatar service unit. The avatar service unit searches in the pre-set correspondence table between the avatar image and the terminal based on the video call connection request to obtain the avatar image corresponding to the first terminal, and sends the avatar image corresponding to the first terminal to the Voice over New Radio platform. At this time, the Voice over New Radio platform receives the avatar image corresponding to the first terminal sent from the avatar service unit.

[0036] Step S300: Perform replacement processing on the target object in the video based on the avatar image to obtain the avatar video data.

[0037] In some embodiments, upon receiving an avatar image, a replacement process is performed on a target object in a video generated in a video call between a first terminal and a second terminal, and the target object in the video is replaced with the avatar image to obtain avatar video data including the avatar image.

[0038] Step S400: Transmit the avatar video data to a base station unit based on the subscriber information, and the base station unit transmits the avatar video data to the second terminal.

[0039] In some embodiments, the voice over new radio platform determines a base station unit connected to the second terminal based on the subscriber information, transmits the avatar video data to the base station unit, and the base station unit transmits the avatar video data to the second terminal, so that the avatar image of the first terminal can be displayed in the video of the video call between the second terminal and the first terminal, and the avatar video call service can be realized on the call interface on the second terminal, without the need for the user to learn again when using it. This implementation solution can adapt to the subsequent evolution route of communication technology, achieve a smooth transition of the call service, and effectively reduce the impact on the network and terminal users.

[0040] In one embodiment, obtain a video call connection request of a first terminal sent from a call session control function unit, send the video call connection request to an avatar service unit, obtain an avatar image corresponding to the first terminal sent from the avatar service unit, perform a replacement process on a target object in the video based on the avatar image to obtain avatar video data, send the avatar video data to a base station unit, and the base station unit sends the avatar video data to a second terminal. In the technical solution of this embodiment, a voice over new radio platform and an avatar service unit are added on a conventional communication network, and an avatar video call service can be realized at a conventional call interface on the terminal, without the need for the user to learn again when using it. This implementation solution is adaptable to the subsequent evolution route of communication technology, can achieve a smooth transition of the call service, and effectively reduce the impact on the network and terminal users.

[0041] In one embodiment, referring to FIG. 4, the calling terminal starts a video call connection request to the first base station unit. The first base station unit transfers this video call connection request to the call session control function unit. The service call session control function unit queries the home subscriber user server for subscriber information based on this video call connection request, generates a video call connection request based on the video call connection request, and then the call session control function unit sends the video call connection request and subscriber information of the first terminal to the Voice over New Radio platform. The Voice over New Radio platform sends the video call connection request to the avatar service unit. The avatar service unit searches in the pre-set correspondence table between the avatar image and the terminal based on the video call connection request to obtain the avatar image corresponding to the first terminal, and sends the avatar image corresponding to the first terminal to the Voice over New Radio platform. The Voice over New Radio platform performs a replacement process on the target object in the video generated in the video call between the first terminal and the second terminal, replaces the target object in the video with the avatar image to obtain avatar video data including the avatar image. The Voice over New Radio platform forwards the video call connection request to the service call session control function unit. The service call session control function unit routes the call to the called home session control function unit. The called home session control function unit transfers the video call connection request to the second base station unit on the called side, addresses the called user using a standard VoLTE call. The second base station unit on the called side transfers the video call connection request to the second terminal that is the called party. When the second terminal rings and goes off-hook, the Voice over New Radio platform and the calling and called terminals complete the media negotiation of the video call and send the avatar video data to the first terminal and the second terminal. The first terminal that is the calling party starts a voice call and activates the simultaneous interpretation function, copies the media stream to the automatic voice recognition technology for voice recognition, obtains the text after voice recognition, overlays the text on the avatar video data and plays it back to the user.

[0042] An avatar service is set for the first terminal, and it is not necessary to set an avatar service for the second terminal. In this case, avatar video data is generated only for the video stream of the first terminal. Alternatively, an avatar service may be set for both the first terminal and the second terminal. In this case, it is necessary to generate avatar video data for the video streams of the first terminal and the second terminal. Alternatively, an avatar service is set for the second terminal, and it is not necessary to set an avatar service for the first terminal. In this case, avatar video data is generated for the video stream of the second terminal. This embodiment is not specifically limited thereto.

[0043] In addition to being used in a video call scenario between two users, the video call control method of this embodiment may also be used in a video call scenario between three or more users. This embodiment is not specifically limited thereto.

[0044] As shown in FIG. 5, FIG. 5 is a flowchart of a video call control method according to another embodiment of the present application. Step S300 includes, but is not limited to, steps S510 and S520.

[0045] Step S510: Obtain video setting requirement information of the first terminal by the avatar service unit.

[0046] Step S520: Based on the video setting requirement information, perform a replacement process on the target object in the video based on the avatar image to obtain avatar video data.

[0047] In some embodiments, before making a video call, the first terminal needs to set avatar service-related information in the avatar service unit. The information that needs to be set includes at least one of the following: the avatar image that needs to be uploaded / selected, the object to be replaced by the avatar image, setting whether the background of the video needs to be blurred, setting whether the avatar service is in a static mode or a dynamic mode, etc. When the avatar service unit receives the setting information of the first terminal, it generates video setting requirement information corresponding to the first terminal. In this case, when the first terminal initiates a video call connection request, the Voice over New Radio platform obtains the video setting requirement information of the first terminal from the avatar service unit, and based on the video setting requirement information, performs a replacement process on the target object in the video based on the avatar image to obtain avatar video data.

[0048] In one embodiment, the Voice over New Radio platform may determine the target object in the video that needs to be replaced based on the video setting requirement information. The target object is the background and / or icon in the video. Based on the avatar image, a replacement process is performed on the target object to obtain avatar video data. That is, the Voice over New Radio platform may partially or completely replace the screen in the video based on the video setting requirement information corresponding to the first terminal. This embodiment is not specifically limited thereto.

[0049] As shown in FIG. 6, FIG. 6 is a flowchart of a video call control method according to another embodiment of the present application. The Voice over New Radio platform includes a service module, a call capability module, and a media module. The video call control method includes, but is not limited to, step S610, step S620, step S630, and step S640.

[0050] Step S610: The call capability module receives a video call connection request of the first terminal from the call session control function unit, and sends the video call connection request to the avatar service unit by the service module.

[0051] Step S620: The service module sends the avatar image corresponding to the first terminal obtained from the avatar service unit to the media module.

[0052] Step S630: The media module performs replacement processing on the target object in the video with the avatar image to obtain avatar video data, and sends the avatar video data to the second terminal by the base station unit.

[0053] In one embodiment, referring to FIG. 7, a first terminal that is making a call starts a video call connection request for a second terminal, receives a response from the second terminal, and the call capability module obtains the video call connection request of the first terminal by the call session control function unit, and sends the video call connection request to the avatar service unit by the service module. Then, the call capability module anchors the audio and video stream to the VoNR+ media plane of the media module based on the avatar service unit / service module (VoNR+ platform) instruction. After the anchoring is completed, the call capability module returns the audio and video media resource URL of the VoNR+ media plane of the media module. Since the first terminal has already set a background or a virtual icon before the call, the avatar service unit determines the video setting requirement information, and instructs the service module (VoNR+ platform) to start a background replacement or a virtual icon replacement to carry the background or virtual icon ID. The service module (VoNR+ platform) notifies the VoNR+ media plane of the media module to start a background replacement or a virtual icon replacement to carry the background or virtual icon ID, and the VoNR+ media plane of the media module replaces the video background or the icon with the specified background or virtual icon.

[0054] In one embodiment, after the replacement is completed, the first terminal may further blur the background by DTMF settings. The VoNR+ media plane of the media module reports the detected DTMF result to the service module (VoNR+ platform). The service module (VoNR+ platform) reports the DTMF result to the avatar service unit. The avatar service unit instructs the VoNR+ platform / VoNR+ media plane to execute the setting result prompt flow. The avatar service unit instructs the service module (VoNR+ platform) to perform background blurring processing, or the service module (VoNR+ platform) instructs the VoNR+ media plane to perform background blurring processing on the local video stream to make the user's avatar icon more prominent.

[0055] As shown in FIG. 8, FIG. 8 is a flowchart of a video call control method according to another embodiment of the present application.

[0056] The video call control method of the embodiment of the present application is used in a first terminal and may include, but is not limited to, step S810 and step S820.

[0057] Step S810: Send a video call connection request characterizing a video call with a second terminal to a base station unit, and sequentially send the video call connection request to an avatar service unit via the base station unit, a call session control function unit, and a voice over new radio platform, so that the voice over new radio platform obtains an avatar image corresponding to the first terminal via the avatar service unit, performs replacement processing on a target object in the video based on the avatar image to obtain avatar video data, and the voice over new radio platform sends the avatar video data to the second terminal via the base station unit.

[0058] Step S820: Obtain video data corresponding to the second terminal transmitted from the base station unit.

[0059] In some embodiments, the calling terminal initiates a video call connection request to the first base station unit. The first base station unit transfers this video call connection request to the call session control function unit. The service call session control function unit queries the home subscriber user server for subscriber information based on this video call connection request, generates a video call connection request based on the video call connection request, and then the call session control function unit transmits the video call connection request and subscriber information of the first terminal to the Voice over New Radio platform. The Voice over New Radio platform transmits the video call connection request to the avatar service unit. The avatar service unit searches in the pre-set correspondence table between the avatar image and the terminal based on the video call connection request to obtain the avatar image corresponding to the first terminal, and transmits the avatar image corresponding to the first terminal to the Voice over New Radio platform. The Voice over New Radio platform performs a replacement process on the target object in the video generated in the video call between the first terminal and the second terminal, replaces the target object in the video with the avatar image, and obtains avatar video data including the avatar image. The Voice over New Radio platform sends the video call connection request to the service call session control function unit. The service call session control function unit routes the call to the called home session control function unit. The called home session control function unit transfers the video call connection request to the second base station unit on the called side, addresses the called user using a standard VoLTE call. The second base station unit on the called side transfers the video call connection request to the second terminal that is the called party. When the second terminal rings and goes off-hook, the Voice over New Radio platform and the calling and called terminals complete the media negotiation of the video call, and the base station units corresponding to the first terminal and the second terminal transmit the avatar video data to the first terminal and the second terminal.

[0060] Before step S810, the first terminal needs to set avatar service-related information in the avatar service unit. For example, it sends the avatar picture and the number information of the first terminal to the avatar service unit. Also, for example, it sends the avatar picture, the number information of the first terminal, and the video setting requirement information to the avatar service unit. Here, the video setting requirement information includes one of the following: replacing the icon in the video with the avatar picture, replacing the background in the video with the avatar picture, replacing the icon in the video with the avatar picture and performing a blurring process on the background in the video, and replacing the icon in the video with the avatar picture and performing an animation effect process on the replaced avatar icon.

[0061] In one embodiment, referring to FIG. 9, the video setting requirement information is to replace the icon in the video with the avatar picture to realize a static avatar service. First, the first terminal adopts a method of opening the 5G new call mini-program tray to trigger the avatar mini-program and enter the home page of the avatar mini-program, where the effects of the avatar and voice announcement are added to the home page. When the first terminal clicks on the service content link to jump to the avatar picture selection page, it selects the avatar picture to fill the video stream, completes the function of the avatar, and may add a voice announcement effect.

[0062] In one embodiment, referring to FIG. 10, the video setting requirement information is to replace the icon in the video with an avatar picture and perform animation effect processing on the replaced avatar icon, so that a dynamic avatar service can be realized. First, a third-party call cloud flow may be introduced. The user can dial the third-party call cloud by the first terminal, thereby triggering the avatar service, starting a video call. The third-party call cloud and the voice over new radio platform complete the creation of the audio / video / DC channel, lower the cloud H5 page during the call. This page inherits the static avatar function, and at the same time, continuously adds a dynamic avatar service to the H5 page, and introduces background replacement and animation effect identification media capabilities. When the first terminal receives the H5 page, it interacts with the avatar service unit. The avatar service unit encodes and decodes the user's video stream based on the virtual character icon selected by the user, identifies the position of the user's face on the screen, zooms the virtual character icon to the same size, and replaces the user's face by adopting an image replacement method. Then, the virtual character image realizes the dynamic avatar service by identifying the moving direction and width of the user icon and performing matching and following.

[0063] In one embodiment, the avatar service can interoperate on different terminals. When the second terminal is a terminal that supports a data channel, the voice over new radio platform transmits the avatar video data to the second terminal through the data transmission channel by the base station unit. Or, when the second terminal is a terminal that does not support a data channel, the voice over new radio platform performs conversion processing on the format of the avatar video data by the base station unit, and transmits the avatar video data after format conversion processing to the second terminal through the video transmission channel.

[0064] In one embodiment, referring to FIG. 11, in a scenario where an avatar service call is realized between a DC terminal and a non-DC terminal (VoLTE terminal), a DC channel is established between the DC terminal and the network, and a real-time video stream transmission channel (RTP over UDP) is established between the non-DC terminal (VoLTE terminal) and the network. The network associates these two transmission channels and realizes the transmission of interaction data between the DC terminal and the non-DC terminal (VoLTE terminal) by format-converting the data in one channel and then transmitting it in another channel.

[0065] In addition, one embodiment of the present application provides a communication device, which includes a processor and a memory. Here, the processor and the memory can be connected by a bus or other means. This embodiment takes the connection by a bus as an example.

[0066] The memory may be used as a non-transitory computer-readable storage medium for storing non-transitory software programs and non-transitory computer-executable programs. Note that the memory may include high-speed random access memory, and may further include non-transitory memory, for example, at least one magnetic disk memory device, a flash memory device, or other non-transitory solid-state memory devices. In some embodiments, the memory may include memory installed remotely from the processor, and these remote memories may be connected to this communication device via a network. Examples of the above network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0067] This communication device may be used in a 5G communication network system and subsequent evolved mobile communication network systems, etc. This embodiment is not specifically limited thereto.

[0068] The communication device of this embodiment does not constitute a limitation to the embodiments of this application, and may include more or fewer members than the number of members shown in the figure, or some combination of members, or different arrangements of members.
