[0085] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0086] The rendering collaboration method provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Among them, the terminal 102 communicates with the server 104 through a network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or can be placed in the cloud or other network servers. Specifically, the rendering collaboration method in the present application is applied in the field of communication technology. The server 104 can be an avatar communication application server, and the terminal can be a mobile terminal for user communication. In this way, in the communication network, the data channel signaling function network element DCSF (DataChannel Signaling Function Network Element) determines the rendering strategy for this avatar communication service according to the terminal attribute information and the service rendering requirements. Then, based on the rendering strategy, the DSCF instructs the terminal or the media gateway to perform avatar rendering. This avatar rendering is used to complete this avatar communication service. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (Virtual Reality, VR) device, an augmented reality (Augmented Reality, AR) device, a smart glasses, etc. The server 104 can be an independent physical server, can also be a server cluster or a distributed system composed of multiple physical servers, or can also be a cloud server providing cloud computing services.

[0087] In an exemplary embodiment, as Figure 2 shown, a rendering collaboration method is provided. Taking the application of this method to the data channel signaling function network element DSCF as an example, it includes the following steps 202 to 204. Among them:

[0088] Step 202, determine the rendering strategy for this avatar communication service according to the terminal attribute information and the service rendering requirements.

[0089] In implementation, in an avatar communication service initiated by an end user, the DSCF determines a rendering strategy for the current avatar communication service according to the terminal attribute information and the service rendering requirements. Among them, the terminal attribute information may include, but is not limited to, terminal rendering capabilities, terminal real-time performance parameters, and so on. The service rendering requirements include the rendering requirements of the user's current avatar communication. For example, whether the user allows network rendering, the avatar special effect requirements for the current avatar communication, etc. The embodiments of the present disclosure do not limit the service rendering requirements.

[0090] Step 204: Based on the rendering strategy, instruct the terminal or the media gateway to perform avatar rendering.

[0091] Among them, avatar rendering is used to complete the current avatar communication service.

[0092] In implementation, during the avatar communication process, the DSCF, based on the rendering strategy, instructs the terminal or the media gateway to perform avatar rendering. Specifically, the rendering strategy includes a first rendering strategy and a second rendering strategy. Among them, the execution ends of the avatar rendering of the first rendering strategy and the second rendering strategy are different, and they also correspond to different avatar rendering interaction logics. In this way, after the DSCF determines a rendering strategy that is more suitable for the current avatar communication service scenario based on the terminal attribute information and the service rendering requirements, the DSCF can issue this rendering strategy, and through this rendering strategy, instruct the execution end corresponding to this rendering strategy (i.e., the terminal or the media gateway) to perform avatar rendering operations, thereby completing the current avatar communication service.

[0093] In the above rendering coordination method, the data channel instruction functional network element dynamically selects whether to perform avatar rendering operations on the network side or the terminal side according to the terminal rendering capabilities, terminal real-time performance parameters included in the terminal attribute information, and the service rendering requirements during the avatar communication process, improving the flexibility of the rendering configuration of the avatar rendering operation and meeting the service development requirements of avatar communication.

[0094] In an exemplary embodiment, in the application scenario of avatar communication, it includes the user's terminal, the multimedia telephone service application server, the data communication signaling functional network element, the media gateway, and the avatar communication application server. In this way, before the terminal initiates an avatar communication service, it is necessary to pre-establish a data transmission channel between the terminal and the avatar communication application server. And the terminal is divided into a terminal that supports rendering processing and a terminal that does not support rendering processing. Therefore, as Figure 3 shown, the method further includes:

[0095] Step 302: When the terminal supports rendering processing, receive a first application program data transmission channel establishment request sent by the terminal.

[0096] Among them, the first application program data transmission channel establishment request carries the terminal attribute information and the service rendering requirements.

[0097] In implementation, when the terminal supports rendering processing, the terminal has the opportunity to perform avatar rendering processing on the video stream. Therefore, when the terminal sends a first application data transfer channel establishment request (i.e., ADC, Application Data Transfer Channel Establishment Request) to the DSCF, information for rendering policy judgment, namely terminal attribute information and service rendering requirements, can be inserted into the first application data transfer channel establishment request. In this way, the first application data transfer channel establishment request sent by the terminal received by the DSCF carries the terminal attribute information and service rendering requirements.

[0098] Step 304, when the terminal does not support rendering processing, receive the second application data transfer channel establishment request sent by the terminal.

[0099] In implementation, when the terminal does not support rendering processing, that is, the terminal side defaults to being unable to perform avatar rendering. Therefore, during the subsequent video stream rendering process, it is inevitable to configure the network side to perform avatar rendering processing on the video stream. Therefore, the terminal does not need to send terminal-side related information to the DSCF and can only request to establish a data transfer channel between the terminal and the avatar communication application server. Therefore, for the second application data transfer channel establishment request sent by the terminal received by the DSCF, other information is inserted into the second application data transfer channel establishment request.

[0100] In this embodiment, according to whether the terminal supports rendering operations, the receiving terminal will send different types of application data transfer channel establishment requests, thereby flexibly determining the rendering policy for this avatar communication service, realizing dynamic selection of rendering configuration during the avatar communication service process, and further improving the rendering effect of avatar rendering.

[0101] In an exemplary embodiment, as Figure 4 shown, after step 302, the method further includes:

[0102] Step 401, if the subscription information corresponding to the avatar communication service is that the service needs to perform the avatar rendering function, save the terminal attribute information and service rendering requirements carried in the first application data transfer channel establishment request to the local storage space.

[0103] In implementation, after receiving a first application data transmission channel establishment request sent by a terminal, the DSCF queries the subscription information of each user's corresponding service stored locally. If, according to the service subscription situation (i.e., subscription information) of the user's avatar communication service, the subscription information corresponding to the avatar communication service is that the service needs to perform the avatar rendering function, the DSCF saves the terminal attribute information and service rendering requirements carried in the first application data transmission channel establishment request in the local storage space for subsequent rendering policy judgment.

[0104] Step 402: Delete the terminal attribute information and service rendering requirements carried in the first application data transmission channel establishment request, and send the first application data transmission channel establishment request after deletion to the avatar communication application server.

[0105] In implementation, after storing the terminal attribute information and service rendering requirements, the DSCF deletes the terminal attribute information and service rendering requirements carried in the first application data transmission channel establishment request to avoid affecting the original function of the first application data transmission channel establishment request. Then, the application data transmission channel establishment request restored to the original information is sent to the avatar communication application server to continue to complete the task of establishing the data transmission channel.

[0106] In this embodiment, for the case where the terminal supports the rendering operation, the application data transmission channel establishment request sent by the terminal to the DSCF will automatically carry the terminal attribute information and service rendering requirements as reference factors for subsequent rendering policy evaluation. After the DSCF parses the terminal attribute information and service rendering requirements based on the subscription information, the DSCF retains the terminal attribute information and service rendering requirements and restores the original application data transmission channel establishment request for subsequent creation of the data transmission channel.

[0107] In an exemplary embodiment, as Figure 5 shown, after step 304, the method further includes:

[0108] Step 501: If the subscription information corresponding to the avatar communication service is that the service needs to perform the avatar rendering function, mark the terminal as a traditional terminal, and send a second application data transmission channel establishment request to the avatar communication application server.

[0109] In implementation, after receiving the second application data transmission channel establishment request sent by the terminal, DSCF queries the contract information of the corresponding services of each user stored locally. If the contract information corresponding to the user's avatar communication service is that the service needs to perform the avatar rendering function, and the second application data transmission channel establishment request does not carry terminal attribute information (for example, terminal rendering capability) and service rendering requirements and other information used for rendering strategy judgment, then it indicates that the terminal does not support rendering operations, and DSCF marks the terminal as a traditional terminal. In addition, DSCF sends the second application data transmission channel establishment request to the avatar communication application server to establish a data transmission channel between the terminal and the avatar communication application server.

[0110] In this embodiment, in the case where the terminal does not support rendering, the terminal is marked as a traditional terminal, and an application data transmission channel establishment request is sent to the avatar communication application server to perform a subsequent data transmission channel creation process.

[0111] In one embodiment, after forwarding the application data transmission channel establishment request sent by the terminal to the avatar communication application server, the DSCF can complete the data transmission channel establishment process based on the feedback of the avatar communication application server, such as Figure 6 As shown, the method also includes:

[0112] Step 601: Receive an application data transmission channel establishment strategy issued by an avatar communication application server.

[0113] The application data transmission channel establishment strategy is used to instruct the multimedia telephone service application server to send a resource reservation request to the media gateway. The resource reservation request is used to instruct the establishment of an application data transmission channel between the terminal and the media gateway.

[0114] During implementation, DSCF receives the application data transmission channel establishment policy issued by the avatar communication application server. The application data transmission channel establishment policy can also be referred to as the ADC establishment policy. The multimedia telephone service application server (MMTeL AS) initiates a resource reservation request to the media gateway (MF, Media Gateway) according to the ADC establishment policy. The media gateway (MF) reserves resources successfully, and the ADC channel between the terminal and the media gateway is successfully established. The MMTel AS returns an ADC establishment success message to the DCSF and the avatar communication application server. The DCSF is integrated with a rendering control module, and the ADC establishment success message is received through the rendering control module. As a result, the ADC channel between the terminal and the avatar communication application server is successfully opened.

[0115] In this embodiment, after the avatar communication application server issues an application data transmission channel establishment policy, a data transmission channel is established based on this application data transmission channel establishment policy to implement data communication between the terminal and the avatar communication application server.

[0116] In an exemplary embodiment, as Figure 7 shown, the terminal attribute information includes the terminal rendering capability and the terminal real-time performance parameters. The specific processing procedure of step 202 includes:

[0117] Step 701: Determine the execution end for performing the avatar rendering operation according to the terminal rendering capability, the terminal real-time performance parameters, the service rendering requirements, and the preset rendering discrimination conditions.

[0118] In implementation, DCSF determines the execution end for performing the avatar rendering operation according to the terminal rendering capability (such as the rendering types supported by the terminal), the terminal real-time performance parameters (such as whether the real-time performance of the terminal's memory, CPU (Central Processing Unit), memory occupancy rate, power, etc. supports the rendering operation), the service rendering requirements (such as whether the user allows network rendering), and the preset rendering discrimination conditions. Specifically, when the terminal supports the rendering operation, DCSF evaluates whether the avatar is rendered by the terminal or by the network side according to the terminal real-time performance parameters, the service rendering requirements, and the preset rendering discrimination conditions, and finally determines the execution end for performing the avatar rendering operation.

[0119] Step 702: Generate a rendering policy for the current avatar communication service based on the execution end.

[0120] In implementation, after determining the execution end for the avatar rendering, DCSF generates a rendering policy corresponding to the current avatar communication service based on the interaction logic of the avatar rendering corresponding to this execution end.

[0121] In this embodiment, through the evaluation of the rendering configuration by the terminal rendering capability, the terminal real-time performance parameters, the service rendering requirements, and the preset rendering discrimination conditions, a rendering policy for executing the current avatar communication service is selected between the terminal and the network side, realizing the dynamic adjustment of the rendering configuration, improving the flexibility of the rendering configuration, and meeting the service development requirements of avatar communication.

[0122] In an exemplary embodiment, as Figure 8 shown, the specific processing procedure for instructing the terminal to perform avatar rendering based on the rendering policy in step 204 includes:

[0123] Step 801: Send the rendering policy and the rendering media data to the terminal through the application data transmission channel, and instruct the terminal to perform avatar rendering based on the rendering policy, the rendering media data, and the user video stream collected by the terminal.

[0124] In implementation, a rendering control module is integrated in the DCSF. After the application data transmission channel between the DCSF and the terminal is established, the rendering control module in the DCSF determines the final rendering strategy. Then, the rendering control module sends the rendering strategy and rendering media data to the terminal through the application data transmission channel. At the same time, the terminal is integrated with a rendering processing module, and the rendering processing module of the terminal performs a rendering operation according to the rendering strategy (the rendering strategy responsible by the terminal). The rendering operation includes: collecting the user video stream, performing avatar rendering on the rendering media data received from the rendering control module of the DCSF and the user video stream to obtain a rendered video stream. Then, sending the rendered video stream to the media gateway through the IMS (IP Multimedia Subsystem) video channel to display the rendered video stream through the media gateway.

[0125] In this embodiment, the rendering processing module in the terminal is instructed to perform a rendering operation through the rendering strategy of the DCSF, and avatar rendering is performed through the terminal, so as to realize flexible setting of the rendering configuration and meet the business development requirements of avatar communication.

[0126] In an exemplary embodiment, when the rendering strategy is to instruct the network side to perform avatar rendering, specific rendering operations are performed through the media gateway on the network side, such as Figure 9 As shown, the specific processing process of instructing the media gateway to perform avatar rendering based on the rendering strategy in step 204 includes:

[0127] Step 901, send the rendering strategy to the terminal through the application data transmission channel, instruct the terminal to collect the user video stream, and send the user video stream to the media gateway.

[0128] In implementation, the rendering control module in the DCSF sends the rendering strategy to the terminal through the application data transmission channel. The rendering strategy is for the network side to perform avatar rendering. Therefore, the rendering control module in the DCSF only instructs the rendering processing module in the terminal to collect the user video stream, and instructs the rendering processing module in the terminal to send the user video stream to the media gateway MF through the IMS video channel.

[0129] Step 902, send the rendering strategy and rendering media data to the media gateway, and instruct the media gateway to perform avatar rendering based on the rendering strategy, rendering media data, and user video stream.

[0130] In implementation, the rendering control module in the DCSF sends the rendering media data of the rendering strategy to the media gateway, and instructs the media gateway to perform avatar rendering based on the rendering strategy, rendering media data, and user video stream. Finally, the media gateway displays the rendered video stream after avatar rendering.

[0131] In this embodiment, the rendering strategy of DCSF is used to instruct the rendering processing module in the terminal to perform a rendering operation, and avatar rendering is performed through the terminal, so as to flexibly set the rendering configuration and meet the business development requirements of avatar communication.

[0132] In an exemplary embodiment, a rendering cooperation method on the terminal side is provided. As Figure 10 shown, the method includes:

[0133] Step 1001: When the terminal supports rendering processing, send a first application data transmission channel establishment request to the data channel signaling function network element.

[0134] Among them, the first application data transmission channel establishment request carries terminal attribute information and service rendering requirements, and is used to instruct the data channel signaling function network element to determine the rendering strategy.

[0135] In implementation, the terminal includes a terminal that supports rendering processing and a terminal that does not support rendering processing. A rendering processing module is added to the terminal that supports rendering processing. In this way, when the terminal supports rendering processing, the terminal sends a first application data transmission channel establishment request, that is, an ADC establishment request, to the data channel signaling function network element DCSF. The ADC establishment request is inserted with terminal attribute information indicating the terminal's rendering ability to support rendering operations (such as the rendering types supported by the terminal), terminal type (whether it is a traditional terminal), and terminal real-time performance parameters (such as whether the real-time performance of the terminal's memory, CPU, battery, etc. supports rendering operations), etc., as well as service rendering requirements. In this way, the evaluation of determining the rendering strategy is participated in by the terminal attribute information and service rendering requirements inserted in the ADC establishment request.

[0136] In this embodiment, for the terminal that supports rendering operations, a rendering processing module is added. By inserting the terminal attribute information and service rendering requirements in the application data transmission channel establishment request through the rendering processing module, the decision-making of the rendering strategy is realized, and the flexibility of the rendering configuration is improved.

[0137] In an exemplary embodiment, if the terminal supports rendering processing and the rendering strategy determined by DCSF is for the terminal to perform the rendering operation, as Figure 11 shown, the method further includes:

[0138] Step 1101: Receive the rendering strategy and rendering media data sent by the data channel signaling function network element.

[0139] In implementation, a rendering processing module is pre-integrated in the terminal, and the rendering processing module receives the rendering strategy and rendering media data sent by the data channel signaling function network element (DCSF). The rendering processing module in the terminal performs a rendering operation according to the rendering strategy.

[0140] Step 1102: Collect the user video stream, and perform avatar rendering based on the rendering policy, the rendered media data, and the user video stream to obtain the rendered avatar video stream.

[0141] In implementation, during the avatar communication process, the terminal collects the user video stream. Then, the terminal performs avatar rendering based on the rendering policy, the rendered media data, and the user video stream to obtain the rendered avatar video stream. The rendering processing module in the terminal sends the rendered avatar video stream to the media gateway through the IMS video channel, so as to display the rendered avatar video stream through the media gateway.

[0142] In this embodiment, when the terminal receives the indication of the rendering policy of DCSF, which is an indication for the terminal to perform the rendering operation based on the rendering policy, the terminal performs avatar rendering based on the rendering policy, the rendered media data, and the user video stream to obtain the rendered avatar video stream, improving the flexibility of the rendering configuration.

[0143] In an exemplary embodiment, as Figure 12 shown, the method further includes:

[0144] Step 1201: When the terminal does not support rendering processing, send a second application data transmission channel establishment request to the data channel signaling function network element.

[0145] Wherein, the second application data transmission channel establishment request is used to instruct the data channel signaling function network element to initiate the creation process of the application data transmission channel between the terminal and the media gateway.

[0146] In implementation, when the terminal does not support rendering processing, the terminal does not have a rendering processing module. Therefore, when the terminal sends the second application data transmission channel establishment request to the data channel signaling function network element, it does not carry information such as the terminal rendering capability. This second application data transmission channel establishment request is used to complete the creation of the application data transmission channel between the terminal and the media gateway, so that after the creation of the application data transmission channel is completed, it is used to receive the rendering policy issued by DCSF. In this way, when the terminal needs to perform avatar communication, based on the indication of the rendering policy, the network side performs avatar rendering, and then the terminal transmits the user video stream to the media gateway through the IMS video channel to assist in completing the avatar rendering process.

[0147] In this embodiment, when the terminal does not support rendering processing, it does not rely on the terminal rendering processing function. The terminal completes the creation process of the application data transmission channel between the terminal and the media gateway, assisting in completing the avatar rendering process, improving the flexibility of the rendering configuration, and meeting the business development requirements of avatar communication.

[0148] In an exemplary embodiment, as Figure 13As shown, the present disclosure provides a specific process example of a rendering collaboration method. In the process example, the terminal supports a rendering processing function, and the example process is as follows:

[0149] Step 1301: The terminal inserts terminal attribute information and service rendering requirements into the application data transmission channel (ADC) establishment request. The terminal attribute information includes terminal rendering capability, terminal real-time performance parameters, etc. The terminal real-time performance parameters include CPU occupancy, memory occupancy, power, etc.

[0150] Step 1302: The terminal sends an application data transmission channel establishment request to a multimedia telephony service application server (MMTeL AS). The application data transmission channel establishment request carries terminal attribute information and service rendering requirements.

[0151] Step 1303: The multimedia telephone service application server sends a data transmission channel establishment request for the application to a data channel signaling function network element (DCSF). The data transmission channel establishment request for the application carries terminal attribute information and service rendering requirements.

[0152] Step 1304, the rendering control module in the data channel signaling function network element DCSF processes according to the user's contracted service status (contract information). If the contract information is that the service needs to execute the avatar rendering function, the terminal attribute information and service rendering requirements carried in the application data transmission channel establishment request are first saved to the local storage space, and then the terminal attribute information and service rendering requirements carried in the application data transmission channel establishment request are deleted.

[0153] Step 1305 , the DCSF forwards the application data transmission channel establishment request for deleting the terminal attribute information and the service rendering requirement to the avatar communication application server (avatar communication AS).

[0154] Step 1306: The avatar communication application server sends an application data transmission channel (ADC) establishment policy to the DCSF.

[0155] Step 1307: DCSF sends an application data transmission channel establishment policy to the multimedia telephony service application server (MMTeL AS).

[0156] Step 1308: The multimedia telephone service application server initiates a resource application, ie, a resource reservation request, to the media gateway (MF) according to the application data transmission channel establishment policy.

[0157] Step 1309: MF resources are successfully reserved, and MF feeds back a message of successful resource application to the multimedia telephone service application server. The application data transmission channel between the terminal and MF is successfully established.

[0158] Step 1310, the MMTeL AS returns a successful application data transfer channel establishment message to the DCSF.

[0159] Step 1311, the DCSF returns a successful application data transfer channel establishment message to the avatar communication application server.

[0160] When the terminal side supports the rendering processing capability, the DCSF needs to make an evaluation and decision based on the terminal attribute information and the service rendering requirements, and decide whether the rendering strategy is to perform avatar rendering on the terminal side or on the network side. The following describes these two cases separately:

[0161] Case of performing avatar rendering on the terminal side:

[0162] Step 1312, the rendering control module in the DCSF receives the successful application data transfer channel establishment message, and determines the rendering strategy for this avatar communication service call based on the terminal type (whether it is a traditional terminal) included in the terminal attribute information, the terminal real-time performance parameters (such as whether the real-time performance of the terminal's memory, CPU, power, etc. supports rendering operations), and the service rendering requirements (such as whether the user allows network rendering), etc.: This avatar communication service is responsible for avatar rendering by the terminal.

[0163] Step 1313, the rendering control module in the DCSF sends the rendering strategy and rendering media data to the terminal through the application data transfer channel.

[0164] Step 1314, the rendering processing module in the terminal performs rendering operations according to the rendering strategy: performs avatar rendering on the rendering media data received from the rendering control module of the DCSF and the user video stream collected by the terminal.

[0165] Step 1315, the terminal sends the rendered avatar video stream to the media gateway through the IMS video channel for the avatar video stream to be displayed on both communication parties.

[0166] Case of performing avatar rendering on the network side:

[0167] Step 1316, the rendering control module in the DCSF receives the successful application data transfer channel establishment message, and determines the rendering strategy for this avatar communication service call based on the terminal type (whether it is a traditional terminal) included in the terminal attribute information, the terminal real-time performance parameters (such as whether the real-time performance of the terminal's memory, CPU, power, etc. supports rendering operations), and the service rendering requirements (such as whether the user allows network rendering), etc.: This avatar communication service is responsible for avatar rendering by the network side.

[0168] Step 1317: The rendering control module in DCSF sends the rendering policy to the terminal through the application data transmission channel.

[0169] Step 1318: The rendering control module in DCSF sends the rendering policy and rendering media data to the media gateway.

[0170] Step 1319: The rendering processing module in the terminal collects the user video stream according to the rendering policy (rendering is responsible by the network side).

[0171] Step 1320: The terminal sends the user video stream to the media gateway through the IMS video channel.

[0172] Step 1321: The media gateway performs the avatar rendering operation according to the rendering policy, rendering media data and the user video stream collected by the terminal, and obtains the avatar video stream.

[0173] In an exemplary embodiment, as Figure 14 shown, the present disclosure provides a specific process example of a rendering collaboration method. In this process example, the terminal does not support the rendering processing function, that is, there is no rendering processing module in the terminal. Therefore, during the rendering configuration process, avatar rendering can only be performed by the network side. The example process is as follows:

[0174] Step 1401: The terminal sends an application data transmission channel establishment request to the Multimedia Telephony Service Application Server (MMTeL AS).

[0175] Step 1402: The Multimedia Telephony Service Application Server sends the application data transmission channel establishment request to the Data Communication Signaling Function Network Element (DCSF).

[0176] Step 1403: The rendering control module in DCSF processes according to the user subscribed service situation (subscription information). Since the terminal attribute information and service rendering requirements are not carried in the application data transmission channel establishment request, the terminal type is marked as a traditional terminal.

[0177] Step 1404: DCSF sends the application data transmission channel establishment request to the Avatar Communication Application Server (Avatar Communication AS).

[0178] Step 1405: The Avatar Communication Application Server sends the application data transmission channel (ADC) establishment policy to DCSF.

[0179] Step 1406: DCSF sends the application data transmission channel establishment policy to the Multimedia Telephony Service Application Server (MMTeL AS).

[0180] Step 1407, the multimedia telephone service application server initiates a resource application to the media gateway (MF) according to the application data transmission channel establishment policy, that is, a resource reservation request.

[0181] Step 1408, the MF resource reservation is successful, and the MF feeds back a resource application success message to the multimedia telephone service application server. The application data transmission channel between the terminal and the MF is successfully established.

[0182] Step 1409, the MMTeL AS returns an application data transmission channel establishment success message to the DCSF.

[0183] Step 1410, the DCSF returns an application data transmission channel establishment success message to the avatar communication application server.

[0184] Step 1411, for the application data transmission channel establishment success message received by the DCSF, according to the terminal type (whether it is a traditional terminal) included in the terminal attribute information, the terminal real-time performance parameters (such as whether the real-time performance of the terminal's memory, CPU, power, etc. supports the rendering operation), and the service rendering requirements (such as whether the user allows network rendering), etc., it is determined that the rendering strategy for this avatar communication service call is: this avatar communication service is responsible for avatar rendering by the network side, and the terminal does not support the rendering processing module.

[0185] Step 1412, the rendering control module in the DCSF sends the rendering strategy and rendering media data to the terminal through the application data transmission channel.

[0186] Step 1413, the terminal captures the user video stream.

[0187] Step 1414, the terminal sends the user video stream to the media gateway (MF) through the IMS video channel.

[0188] Step 1415, the media gateway performs avatar rendering operations according to the rendering strategy, rendering media data, and the user video stream captured by the terminal.
