[0029] Based on the network consisting of the VoLTE SBC network element for executing the video call control method shown in Figure 1 and the network element for executing the video call control method shown in Figure 2, the following describes various embodiments of the video call control method of this application to solve the problems in the above embodiment.

[0030] As shown in Figure 3, Figure 3 is a flowchart of a video call control method according to one embodiment of the present application, and 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, steps S100, S200, and S300.

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

[0032] In some embodiments, when a first terminal needs to perform voice-over-new-radio communication with a second terminal, it sends a video call connection request to a base station unit, which then forwards this video call connection request to a call session control function unit, which 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 transmits the first terminal's video call connection request and subscriber information to the voice-over-new-radio platform, which receives the video call connection request and subscriber information.

[0033] The first terminal may be a calling terminal or a receiving terminal, and this embodiment does not specifically limit it to either. When the first terminal is a calling terminal, the second terminal is a receiving terminal, or when the first terminal is a receiving terminal, the second terminal is a calling terminal.

[0034] Step S200: A video call connection request is sent to the avatar service unit, and an avatar image corresponding to the first terminal is received from the avatar service unit.

[0035] In some embodiments, the Voice Over New Radio platform sends a video call connection request to an avatar service unit, the avatar service unit retrieves an avatar image corresponding to a first terminal by searching a pre-configured correspondence table between avatar images and terminals based on the video call connection request, and transmits the avatar image corresponding to the first terminal to the Voice Over New Radio platform, at which point the Voice Over New Radio platform receives the avatar image corresponding to the first terminal transmitted from the avatar service unit.

[0036] Step S300: Based on the avatar image, a replacement process is performed on the target object in the video to obtain avatar video data.

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

[0038] Step S400: Based on subscriber information, avatar video data is transmitted to the base station unit, which then transmits the avatar video data to the second terminal.

[0039] In some embodiments, the Voice Over New Radio platform determines a base station unit to connect to a second terminal based on subscriber information, transmits avatar video data to the base station unit, and the base station unit transmits the avatar video data to the second terminal, thereby displaying the avatar image of the first terminal in the video of a video call between the second terminal and the first terminal. This realizes an avatar video call service in the call interface on the second terminal, eliminating the need for users to learn how to use it again. This implementation method is adaptable to subsequent evolutionary paths of communication technology, achieving a smooth transition of call services and effectively reducing the impact on the network and terminal users.

[0040] In one embodiment, a video call connection request from a first terminal is received from a call session control function unit, the video call connection request is sent to an avatar service unit, an avatar image corresponding to the first terminal is received from the avatar service unit, a replacement process is performed on the target object in the video based on the avatar image to obtain avatar video data, the avatar video data is sent to a base station unit, and the base station unit sends the avatar video data to a second terminal. In this embodiment, a voice-over-new radio platform and an avatar service unit are added on top of a conventional communication network, enabling avatar video call services to be implemented on the conventional call interface on the terminal. Users do not need to learn anything new when using this solution, and this implementation method is adaptable to the subsequent evolution of communication technology, enabling a smooth transition of call services and effectively reducing the impact on the network and terminal users.

[0041] In one embodiment, referring to Figure 4, the calling terminal initiates a video call connection request to the first base station unit, the first base station unit forwards 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 the call session control function unit transmits the first terminal's video call connection request and subscriber information 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 retrieves the avatar image corresponding to the first terminal by searching a pre-configured correspondence table between avatar images and terminals based on the video call connection request, transmits the avatar image corresponding to the first terminal to the Voice Over New Radio platform, and the Voice Over New Radio platform performs a replacement process on the target object in the video generated by the video call between the first terminal and the second terminal. The avatar image replaces the target object in the video to obtain avatar video data containing 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 forwards the video call connection request to the called second base station unit, which addresses the called user using a standard VoLTE call. The called second base station unit forwards the video call connection request to the called second terminal. When the second terminal rings and goes off-hook, the Voice Over New Radio platform and the calling / called terminal complete media negotiation for the video call and transmit the avatar video data to the first and second terminals. The calling first terminal initiates the voice call, activates the simultaneous interpretation function, replicates the media stream to automatic voice recognition technology for voice recognition, obtains the characters after voice recognition, and overlays the characters onto the avatar video data for playback to the user.

[0042] The avatar service may be configured on the first terminal but not on the second terminal; in this case, avatar video data is generated only for the video stream of the first terminal. Alternatively, the avatar service may be configured on both the first and second terminals; in this case, avatar video data must be generated for the video streams of both the first and second terminals. Alternatively, the avatar service may be configured on the second terminal but not on 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 to these configurations.

[0043] The video call control method of this embodiment may be used not only for a two-user video call scenario, but also for a three- or three-or-more-user video call scenario, and this embodiment is not specifically limited to that.

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

[0045] Step S510: The avatar service unit obtains video configuration requirements information for the first terminal.

[0046] Step S520: Based on the video setting requirements information, a replacement process is performed 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 configure avatar service-related information with the avatar service unit. The information that needs to be configured includes at least one of the following: the avatar image to be uploaded / selected, the object to be replaced by the avatar image, whether or not the video background should be blurred, and whether the avatar service should be set to static or dynamic mode. When the avatar service unit receives the configuration information from the first terminal, it generates video configuration 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 can obtain the video configuration requirement information from the avatar service unit and, based on the video configuration requirement information, perform 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 target objects in the video that need to be replaced based on video configuration requirements information, where the target objects are the background and / or icons in the video, and perform a replacement process on the target objects based on the avatar image 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 video configuration requirements information corresponding to the first terminal, and this embodiment is not specifically limited thereto.

[0049] As shown in Figure 6, Figure 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, steps S610, S620, S630, and S640.

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

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

[0052] Step S630: The media module replaces the target object in the video with the avatar image to obtain avatar video data, and the base station unit transmits the avatar video data to the second terminal.

[0053] In one embodiment, referring to Figure 7, the first terminal, which is making the call, initiates a video call connection request to the second terminal, receives a response from the second terminal, the call capability module obtains the video call connection request from 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, and the call capability module then anchors the audio video stream to the VoNR+ media plane of the media module based on the instructions of the avatar service unit / service module (VoNR+ platform), and after anchoring is complete, returns the audio video media resource URL of the VoNR+ media plane of the media module. Because the first terminal has already set a background or virtual icon before the call is made, the avatar service unit determines the video setting requirements information and instructs the service module (VoNR+ platform) to activate background replacement or virtual icon replacement to carry the background or virtual icon ID. The service module (VoNR+ platform) then notifies the media module's VoNR+ media plane to activate background replacement or virtual icon replacement to carry the background or virtual icon ID. The media module's VoNR+ media plane then replaces the video background or icon with the specified background or virtual icon.

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

[0055] As shown in Figure 8, Figure 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 this application is used in a first terminal and may include, but is not limited to, steps S810 and S820.

[0057] Step S810: The Voice Over New Radio Platform transmits a video call connection request to the base station unit, which is characterized as making a video call with a second terminal. The Voice Over New Radio Platform then transmits the video call connection request to the avatar service unit via the base station unit, the call session control function unit, and the Voice Over New Radio Platform. The Voice Over New Radio Platform obtains an avatar image corresponding to the first terminal via the avatar service unit, and obtains avatar video data by performing a replacement process on the target object in the video based on the avatar image. The Voice Over New Radio Platform then transmits the avatar video data to the second terminal via the base station unit.

[0058] Step S820: Retrieve 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 a first base station unit, the first base station unit forwards this video call connection request to a 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 the call session control function unit transmits the first terminal's video call connection request and subscriber information 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 retrieves the avatar image corresponding to the first terminal by searching a pre-configured correspondence table between avatar images and terminals based on the video call connection request, transmits the avatar image corresponding to the first terminal to the Voice Over New Radio platform, and the Voice Over New Radio platform performs a video call between the first terminal and the second terminal. The process involves replacing the target object in the generated video with an avatar image to obtain avatar video data containing the avatar image. The Voice Over New Radio platform then forwards the video call connection request to the service call session control unit, which routes the call to the called home session control unit. The called home session control unit forwards the video call connection request to the called second base station unit, which addresses the called user using a standard VoLTE call. The called second base station unit forwards the video call connection request to the called second terminal, and once the second terminal rings and goes off-hook, the Voice Over New Radio platform and the called terminal complete the media negotiation for the video call, and the base station units corresponding to the first and second terminals transmit the avatar video data to the first and second terminals.

[0060] Prior to step S810, the first terminal must configure avatar service-related information with the avatar service unit. For example, it may send the avatar picture and the first terminal's number information to the avatar service unit, and also send the avatar picture, the first terminal's number information, and video setting requirement information to the avatar service unit. Here, the video setting requirement information includes one of the following: replacing the icons in the video with the avatar picture; replacing the background in the video with the avatar picture; replacing the icons in the video with the avatar picture and applying a blur effect to the background in the video; and replacing the icons in the video with the avatar picture and applying an animation effect to the replaced avatar icons.

[0061] In one embodiment, referring to Figure 9, the video setting requirements information is to replace the icons in the video with avatar pictures and realize a static avatar service. First, the method adopted is to open the 5G new call mini-program tray on the first terminal to trigger the avatar mini-program, and then enter the avatar mini-program homepage, where the avatar and voice announcement effects are added. Alternatively, by clicking the service content link on the first terminal to jump to the avatar picture selection page, an avatar picture can be selected and filled into the video stream, completing the avatar function and adding voice announcement effects.

[0062] In one embodiment, referring to Figure 10, the video setting requirements information is to replace the icon in the video with an avatar picture and apply animation effect processing to the replaced avatar icon, thereby realizing a dynamic avatar service. First, a third-party call cloud flow may be introduced, and the user can dial the third-party call cloud with the first terminal, thereby triggering the avatar service and initiating a video call. The third-party call cloud and the Voice Over New Radio platform complete the creation of the audio video / DC channel and bring down a cloud H5 page during the call. This page inherits the static avatar functionality and, along with the H5 page, subsequently adds a dynamic avatar service, introducing background replacement and animation effect recognition 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 person icon selected by the user, identifies the position of the user's face on the screen, zooms the virtual person icon to the same size, and replaces the user's face using an image replacement method. The virtual person then identifies the direction and width of movement of the user icon and performs matching and following, thereby realizing a dynamic avatar service.

[0063] In one embodiment, the avatar service can be interoperable between different terminals. If the second terminal is a terminal that supports a data channel, the Voice Over New Radio Platform transmits avatar video data to the second terminal via the data transmission channel using a base station unit. Alternatively, if the second terminal is a terminal that does not support a data channel, the Voice Over New Radio Platform performs a format conversion on the avatar video data using a base station unit and transmits the format-converted avatar video data to the second terminal via the video transmission channel.

[0064] In one embodiment, referring to Figure 11, in a scenario where avatar service calls are 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 transmits the data in one channel after format conversion over the other, thereby realizing the transmission of interaction data between the DC terminal and the non-DC terminal (VoLTE terminal).

[0065] Furthermore, one embodiment of this application provides a communication device comprising a processor and memory, wherein the processor and memory may be connected by a bus or by other means, and this embodiment takes a bus connection as an example.

[0066] Memory may be used as a non-temporary computer-readable storage medium to store non-temporary software programs and non-temporary computer-executable programs. Memory may also include high-speed random-access memory, and may further include non-temporary memory, such as at least one magnetic disk memory device, a flash memory device, or other non-temporary solid-state memory devices. In some embodiments, memory may include memory located remotely from the processor, and these remote memories may be connected to this communication equipment via a network. Examples of such networks 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 5G communication network systems and subsequent advanced mobile communication network systems, and this embodiment is not specifically limited to these.
