Among them, there are two types of data transmission channels: the Bootstrap Data Channel (BDC) and the Application Data Channel (ADC). The Bootstrap Data Channel can be used to download applications from the Data Channel Signaling Function (DCSF), and the Application Data Channel can be used to transmit application data.

[0005] On this basis, user equipment (UE) can conduct high-definition audio and video calls using digital human avatars based on the Internet Protocol Multimedia Subsystem (IMS). Typically, a UE can initiate IMS communication with a peer UE, decode the acquired avatar repository (AR) media, perform AR media rendering locally, and display the rendered avatar on the screen, completing the digital human call.

[0056] The following describes the user-to-user (Person to Person, P2P) ADC establishment process, the user-to-application-to-user (Person to Application to Person, P2A2P) ADC establishment process, and the user-to-application (Person to Application, P2A) ADC establishment process in the digital human communication process with reference to the accompanying drawings.

[0057] 1. P2P ADC establishment process

[0058] As shown in FIG. 2 , FIG. 2 is a schematic diagram of a process of establishing a P2P ADC. The process of establishing a P2P ADC may include the following steps S100 to S119 .

[0059] S100, IMS session and BDC have been established.

[0060] The selected data channel application can be downloaded to UE1 or UE2.

[0061] S101 and UE1 send a Session Initiation Protocol (SIP) reinviter request with an updated Session Description Protocol (SDP) to the IMS Application Server (AS) via the Proxy Call Session Control Function (P-CSCF) and Serving-Call Session Control Function (S-CSCF). The updated SDP contains the bootstrap data channel information, the requested application data channel, and the associated data channel (DC) application binding information.

[0062] S102: The IMS AS verifies the user subscription data to determine whether the media change request event should be notified to the DCSF.

[0063] S103. The IMS AS notifies the DCSF of the media change request event through Nimsas_SessionEventControl_Notify.

[0064] The Nimsas_session event control_notification may include a media change request event, a session identifier (Identity, ID), an event direction, an event initiator, and a media information list.

[0065] S104. After receiving the session event notification, the DCSF determines a policy for processing the application data channel establishment request based on the notification and / or relevant parameters in the DCSF service-specific policy (ie, the associated DC application binding information).

[0066] S105. The DCSF determines that the added application data channel media descriptor provided by the SDP takes UE 2 as the target endpoint and does not need to be anchored on a local Management Function (MF) or Media Resource Function (MRF).

[0067] S106. The DCSF responds to the notification received in step S13.

[0068] S107-S108. The IMS AS sends the re-invite to the initiating S-CSCF, and then sends it to the terminating network (Terminating network) / UE2.

[0069] S109-S111, the terminating network / UE2 returns a 200 OK response.

[0070] The 200 OK response may include an SDP answer for the application data channel to the originating network. Based on the DC application binding information received in the re-invite SDP offer, UE2 may need to download the corresponding DC application sent in the SDP offer and associate it with the requested application DC.

[0071] It should be noted that the terminating network / UE2 can decide whether to use the DC application based on the received DC application binding information.

[0072] S112. The IMS AS notifies the DCSF that the data channel modification is successful.

[0073] S113. The DCSF responds to the notification received in step S112.

[0074] S114-S115. The IMS AS sends a 200 OK response to the initiating S-CSCF and P-CSCF.

[0075] S116. The originating network P-CSCF performs a Quality of Service (QoS) process on the application data channel media based on the SDP answer information from the 200 OK response.

[0076] S117. The P-CSCF returns a 200 OK response to UE1.

[0077] S118. UE1 sends an ACK to the terminating network / UE2.

[0078] S119: Establish an application data channel between UE1 and UE2.

[0079] 2. P2A2P ADC establishment process

[0080] The P2A2P process requires the establishment of application data channels from UE1 to the MF and from UE2 to the MF. These two application data channels are associated with the same application. This allows UE1 and UE2 to interact with the same DC application server at the same time, and the DC application server can associate the data exchanged with the two UEs.

[0081] As shown in FIG3 , FIG3 is a schematic diagram of a process of establishing a P2A2P ADC. The process of establishing a P2A2P ADC may include the following steps S200 to S226 .

[0082] S200: The IMS session and the bootstrap data channel are successfully established.

[0083] The selected data channel application can be downloaded to UE1 or UE2.

[0084] S201. UE1 sends a SIP re-invite request with updated SDP to the IMS AS.

[0085] The updated SDP includes the boot data channel, application data channel information and associated DC application binding information.

[0086] S202: The IMS AS verifies the data channel media description information and / or user subscription data to determine whether the DCSF needs to be notified.

[0087] S203: The IMS AS selects and notifies the DCSF of the call event and the data channel establishment request.

[0088] S204. The DCSF decides how to process the application data channel establishment request according to the parameters in the IMS AS and / or DCSF service-specific policy notification.

[0089] The parameters in the above-mentioned specific policy notification may be the associated DC application binding information.

[0090] S205: The DCSF determines that the application data channel media (meida) added in the SDP offer requires a DC application server as the originating and terminating UE endpoint, and that the application DC must be anchored to the MF or MRF. The DCSF communicates with the DC application server to implement data center resource control. Once the application data channel is established, the DC application server will send and receive traffic to UE1 over the MDC2 interface.

[0091] S206. The DCSF invokes the nimsas_media control (medicontrol) service to send a data channel control request to the IMS AS, including information on how to relay the data channel media through the MDC2 interface.

[0092] S207: The IMS AS reserves data channel media resources in the MF via DC2 or in the MRF via Mr / Cr based on the data channel media information received from the DCSF. These requests sent by the IMS AS are used to create two associated resources in the MF / MRF.

[0093] Among them, one of the two associated resources can be used to initiate the UE (ie, UE1), and the other can be used to terminate the UE (ie, UE2).

[0094] S208. The IMS AS notifies the DCSF of the medi control command control response.

[0095] S209 : The DCSF communicates with the data center application server to control data center resources and provides information about data channel media resources reserved in the MF.

[0096] S210. DCSF stores the media resource information and responds to the Nimsas notification request.

[0097] S211-S212. The IMS AS sends a re-INVITE.

[0098] The re-INVITE may include an SDP proposal provided by the MF or MRF for the application data channel, which is then sent to the original S-CSCF and then to the terminating network / UE2.

[0099] S213-S216, the terminating network / UE2 returns 200 OK.

[0100] The 200 OK may contain SDP responses for audio / video and application data channels. The P-CSCF performs QoS procedures for the application data channel media based on the SDP in the 200 OK. Based on the DC application binding information received in the reinvite, UE2 may need to download the corresponding DC application sent in the SDP offer and associate it with the requested application DC.

[0101] It should be noted that the UE may determine whether to use the data center application according to the received data center application binding information.

[0102] S217: The IMS AS notifies the DCSF of the success result of the MediaChangeRequest event.

[0103] S218. DCSF updates the media resources in MF / MRF through IMS AS.

[0104] S219. DCSF responds to the notification received in step 17.

[0105] S220-S221. The IMS AS includes an SDP response of the application data channel to UE1 in the 200OK, and sends the 200OK to the S-CSCF and the P-CSCF.

[0106] S222: The originating network P-CSCF performs a QoS process on the application data channel media based on the SDP in the 200 OK.

[0107] S223: P-CSCF returns 200 OK to UE1.

[0108] S224. UE1 sends an ACK to the terminating network / UE2.

[0109] S225: An application data channel is established between UE 1 and the DC application server via the MF or MRF. The MF or MRF forwards the data channel traffic between UE 1 and the DC application server via MDC 2.

[0110] S226: An application data channel is established between UE 2 and the DC application server via the MF or MRF. The MF or MRF forwards the data channel traffic between UE 2 and the DC application server via MDC2.

[0111] 3. P2A ADC establishment process

[0112] As shown in FIG4 , FIG4 is a schematic diagram of a process of establishing a P2A ADC. The process of establishing a P2A ADC may include the following steps S300 to S327 .

[0113] S300: The IMS session and the bootstrap data channel are successfully established.

[0114] The selected data channel application can be downloaded to UE1 or UE2.

[0115] S301. UE1 sends a SIP re-invite request with updated SDP to the IMS AS.

[0116] The updated SDP includes the boot data channel, application data channel information and associated DC application binding information.

[0117] S302: The IMS AS verifies the data channel media description information and / or user subscription data to determine whether the DCSF needs to be notified.

[0118] S303: The IMS AS selects and notifies the DCSF of the call event and the data channel establishment request.

[0119] S304: After receiving the session event notification, the DCSF determines a policy for processing the application data channel establishment request based on the notification and / or relevant parameters in the DCSF service-specific policy.

[0120] S305: The DCSF determines that the added offered application data channel media uses the DC application server as the target endpoint and needs to be anchored in the MF or MRF.

[0121] S306: The DCSF invokes the nimsas_medicontrol service operation to instruct the IMS AS to terminate the media flow initiated from the UE to the MF.

[0122] The instruction instructing the IMS AS to terminate the media flow initiated from the UE to the MF also includes information to be used by the MF, that is, the data channel media should be forwarded through the MDC2 interface.

[0123] S307. The IMS AS calls the media termination descriptor list (Nmf_MRM_Create) service operation and instructs the MF to establish an application data channel and reserve data channel media resources according to the DC media information received from the DCSF.

[0124] If MRF is used, the IMS AS can use Mr / Cr to MRF to reserve data channel media resources.

[0125] S308. The IMS AS notifies the DCSF of a medicontrol command control response.

[0126] S309. DCSF stores the media resource information and sends a P2A application data channel establishment request to the DC application server through DC3 / DC4.

[0145] Furthermore, the following describes UE-centric augmented reality (AR) media rendering and network-side device-centric AR media rendering with reference to the accompanying drawings.

[0146] 1. UE-centered digital human media rendering

[0147] As shown in FIG5 , FIG5 is a schematic diagram of a process of AR media rendering centered on a UE. The AR media rendering process centered on a UE may include the following steps S401 to S406 .

[0148] S401. UE1 and UE2 initiate IMS communication, including establishing a bootstrap data channel.

[0149] S402: The user upgrades the IMS session through the AR experience.

[0150] Specifically, UE1 can initiate a re-invite and add the media descriptors required by the AR application to establish end-to-end, such as RTP and / or application data channels. The application data channel can be anchored in the MF / MRF.

[0151] In this scenario, the UE can perform AR media rendering based on the AR data of the local application.

[0152] It should be noted that, in other cases, the UE may obtain AR data from other sources, such as a peer UE, an AR AS, and the like.

[0153] S403 : UE1 captures AR data, performs AR media rendering locally, and then encodes AR media, such as audio / video media streams.

[0154] S404 : UE1 sends AR media to the peer end through the established media connection.

[0155] S405 : UE1 receives AR media from the peer end through the established media connection.

[0156] S406: UE1 decodes the AR media, renders it locally, and displays it on its screen.

[0157] 2. AR media rendering centered on network-side devices

[0158] As shown in FIG6 , FIG6 is a schematic diagram of a process of AR media rendering centered on a network-side device. The AR media rendering process centered on a network-side device may include the following steps S501 to S509 .

[0159] S501. UE1 initiates an IMS session and establishes an audio and video session connection with UE2.

[0160] It is understandable that UE1 and UE2 can establish the bootstrap data channel at the same time.

[0161] S502 : UE1 decides to request network media rendering based on its own status, such as power, signal, computing capability, internal storage, etc.

[0162] S503 : UE1 completes AR media rendering negotiation with the AR application server.

[0163] S504: If the negotiation in step S503 is successful, UE1 initiates a new P2A application data channel for ARAR data transmission between UE1 and the network. During the P2A application data channel establishment process, DCSF will instruct MF / MRF through IMS AS on how to establish the data channel and corresponding media processing specifications.

[0164] Optionally, in S505 , the IMS AS initiates a media renegotiation request to UE1 to connect the audio and video media streams of UE1 to the MF / MRF.

[0165] S506 : The IMS initiates a media renegotiation request to UE2 to connect the audio and video media streams of UE2 to the MF / MRF.

[0166] If the status of UE1 changes, such as low power consumption, low computing power, etc., UE1 can request to change the network rendering content.

[0167] S507 : UE1 captures AR data and sends the AR data to MF / MRF for network-assisted rendering.

[0168] S508 : Based on the AR data received from UE1 and / or the instruction received from the AR AS, the MF / MRF performs AR media rendering according to the negotiation result of step 3 .

[0169] S509 : The MF / MRF sends the presented audio / video media stream to UE2.

[0170] In the digital human communication method provided by the embodiment of the present application, during the process of establishing an application data channel for digital human communication, if the first UE requires other devices to perform digital human media rendering for it, the first UE can provide digital human-related information to the second UE or the first network-side device at the opposite end, so that the digital human media rendering can be performed for the first UE by the second UE or the first network-side device at the opposite end, thereby improving the effect of digital human calls conducted in the digital human image.

[0171] The following, in combination with the accompanying drawings, describes in detail the digital human communication method, device, UE, network-side equipment, medium and computer program product provided in the embodiments of the present application through some embodiments and their application scenarios.

[0178] In some embodiments of the present application, the first network-side device may be an MF.

[0179] In some embodiments of the present application, the above-mentioned digital human identification may be a digital human ID (Avatar ID).

[0180] In some embodiments of the present application, the first digital human identifier may be used to identify a first digital human avatar. The user may use the first digital human avatar during a digital human call.

[0181] In some embodiments of the present application, the first UE may be a device that requires the first network-side device to perform digital human media rendering for it.

[0182] Exemplarily, the first digital human identifier may be a digital human identifier selected by a user of the first UE.

[0183] In some embodiments of the present application, the first digital human image may be avatar metadata.

[0184] It should be noted that the above-mentioned digital human image metadata can also be called digital human image, digital human image information, data human data, basic digital human, digital human information, digital human model and other different names, but technical personnel in this field can understand that although these names are different, the essence is the same.

[0185] Specifically, digital avatar metadata is the 2D or 3D representational content of an avatar stored in a file; alternatively, digital avatar metadata is the 2D or 3D representational model of an avatar stored in a file that can be accessed via a Uniform Resource Locator (URL). Digital avatar metadata can be stored in an Avatar Repository (AR), a Data Channel Avatar Repository (DCAR), or other network functions. Digital avatar metadata, or a reference to digital avatar metadata, such as an identifier, can be associated with each user and / or with each user's user identifier. Digital avatar metadata needs to correspond to the face, the entire body, or a portion of the body. Other metadata can be associated with the avatar metadata, such as format, resolution, access / usage permissions and time, creation date, permissions, etc.

[0191] In the digital human communication method provided in the embodiments of the present application, if a first UE requires another device to render the digital human for it, such as when the first UE is low on battery, has insufficient computing power, or does not want to render on its own, then a second UE or network-side device on the other end can perform the rendering. In this case, the urgent problem of allowing the second UE or network-side device on the other end to obtain the digital human image and perform the rendering is solved.

[0192] In some embodiments of the present application, the first network side device can obtain the digital human image that performs digital human media rendering for the first UE by obtaining a message containing at least one of a digital human identifier, an address indicating downloading the digital human image, and an address indicating the second network side device.

[0193] In the digital human communication method provided in the embodiment of the present application, the first network side device can obtain at least one of the digital human identifier, the address indicating the downloading of the digital human image, and the address indicating the second network side device during the establishment of the application data channel for digital human communication, thereby performing digital human media rendering for the UE to improve the effect of digital human communication.

The fourth network device may then send the first digital human identifier to the second network device. Upon receiving the first digital human identifier, the second network device may return the first address information corresponding to the first digital human identifier to the fourth network device. The fourth network device may then include the first address information in a second message and send it to the first network device.

[0214] In some embodiments of the present application, the third network-side device may reserve data channel media resources in the MF through DC2 or in the MRF through Mr / Cr based on the data channel media information received from the fourth network-side device.

[0215] In some embodiments of the present application, the request sent by the third network-side device may be used to create two associated resources in the MF / MRF, one of which may be used to initiate the UE (i.e., the first UE) and the other may be used to terminate the UE (i.e., the second UE).

[0216] In some embodiments of the present application, the third network-side device may provide a download URL of the digital human image to the first network-side device, so that the first network-side device can subsequently perform digital human media rendering for the first UE.

[0226] In this way, when the first message contains at least one of the first digital human identifier and the second address information, the first network side device can obtain the first address information corresponding to the first digital human identifier from the second network side device or the third network side device, and download the digital human image based on the first address information, thereby improving the flexibility of the first network side device in obtaining the first address information.

[0227] In some embodiments of the present application, the above step of "the first network-side device downloads the digital human image based on the first address information" may include the following step A.

[0228] Step A: The first network-side device downloads the digital human image based on the first address information through the application data channel.

[0229] In some embodiments of the present application, after the application data channel is established, the first network-side device may download the digital human image based on the first address information through the application data channel.

[0230] In this way, the first network-side device can obtain the address information required to download the digital human image during the establishment of the application data channel, so that the digital human image can be downloaded immediately after the application data channel is established, thereby improving the efficiency of rendering for the UE.

[0231] In some embodiments of the present application, before the above step 201, the digital human communication method provided by the embodiment of the present application may further include the following step 206.

[0232] Step 206: The first network side device negotiates with the first user equipment UE whether to perform digital human media rendering for the first UE based on at least one of the capability information and power information of the first user equipment UE and the capability information of the first network side device.

[0235] In some embodiments of the present application, when the first network side device performs digital human media rendering for the first UE, the first network side device and the first UE can negotiate whether the first network side device performs digital human media rendering for the first UE based on at least one of the capability information and power information of the first user equipment UE, and the capability information of the first network side device.

[0236] In this way, digital human media rendering can be performed for the UE while ensuring that the first network-side device has the capability of performing digital human media rendering.

[0237] In some embodiments of the present application, the digital human communication method provided by the embodiments of the present application may further include the following step 207.

[0238] Step 207: After the application data channel is established, the first network-side device performs digital human media rendering.

[0239] In some embodiments of the present application, the first network-side device can obtain the address information required to download the digital human image during the establishment of the application data channel, so that the digital human image can be downloaded immediately and the digital human media rendering can be performed after the application data channel is established, thereby improving the efficiency of rendering for the UE.

[0249] Step 207a: After the application data channel is established, the first network-side device performs digital human media rendering on the digital human image based on the digital human-related data of the user of the first UE.

[0250] In some embodiments of the present application, the first UE may send the captured user's character information as digital human-related data to the first network-side device, so that the first network-side device may perform digital human media rendering on the digital human image based on the digital human-related data.

[0251] It can be understood that after the first network side device obtains the digital human related data, it performs digital human media rendering on the digital human image based on the digital human related data. The rendered digital human media can have the same or similar expressions, actions, sounds and other features as the user of the first UE, thereby improving the effect of digital human communication.

[0252] In some embodiments of the present application, before the above step 209, the digital human communication method provided by the embodiment of the present application may further include the following step 210.

[0253] Step 210: The first network-side device sends a seventh message to the first UE, where the seventh message is used to indicate that the downloading of the digital human image is complete.

[0254] In some embodiments of the present application, the first network-side device may send a seventh message to the first UE after the download of the digital human image is completed, to notify the first UE that the digital human-related data may be sent to the first network-side device, so that the rendered digital human media has a better display effect.

[0255] The following takes the first UE as UE1, the second UE as UE2, the first network side device as MF, the second network side device as AR, and the third network side device as IMS AS as an example to illustrate the digital human communication method provided in the embodiment of the present application.

[0262] In some embodiments of the present application, the above-mentioned call event and data channel establishment request may carry the first message provided by the UE in the SDP offer.

[0263] For example, UE1 may provide a selected first digital human identifier, and MF subsequently needs to obtain the corresponding digital image data from AR and perform rendering.

[0264] S605-1. After obtaining the first digital human identifier, the DCSF requests the AR for the digital human image.

[0265] In some embodiments of the present application, the request for the digital human image may carry the first digital human identifier.

[0266] S605-2. AR returns the download URL corresponding to the digital human image

[0267] It should be noted that if the first message in step S601 carries the download URL corresponding to the digital human image, step S605 may not be performed.

[0268] S606: DCSF returns the download URL to the IMS AS.

[0269] S607: Based on the data channel media information received from the DCSF, the IMS AS reserves the data channel media resources at the MF via DC2 or at the MRF via Mr / Cr, and provides the MF with the download URL of the digital human image.

[0270] S627: After the application data channel is successfully established, the MF can download the avatar data through the obtained download URL.

[0271] In some embodiments of the present application, the MF may also directly download the digital human image after receiving the download URL, which is not specifically limited in the present application.

[0272] S628 : The MF performs rendering of the digital human image for the UE.

[0273] In this way, the first network side device can obtain at least one of the digital human identification, the address indicating the downloading of the digital human image, and the address indicating the second network side device during the establishment of the application data channel for digital human communication, so as to perform digital human media rendering for the UE to improve the effect of digital human communication.

[0275] S707: After the ADC is established, UE1 provides the MF with a download URL for the digital human image through a data channel.

[0276] In some embodiments of the present application, the download URL of the digital human image may be obtained by UE1 from BDC.

[0277] S708. MF downloads the digital human image according to the download URL.

[0278] S709 , MF notifies UE1 that the downloading of the digital human image has been completed.

[0279] S710. UE1 obtains the user's digital human related data and sends it to MF.

[0280] In some embodiments of the present application, the aforementioned digital human-related data may include, but is not limited to, information such as the user's gestures, face, and voice.

[0281] In some embodiments of the present application, the aforementioned digital human-related data may be used to render digital human media data.

[0282] S711, MF performs digital human media rendering

[0283] S712. The MF sends the rendered digital human media to the peer UE2 via RTP or ADC.

[0284] In some embodiments of the present application, when the established data channel is P2A ADC, the MF may send the rendered digital human media to UE2 via RTP; when the established data channel is P2A2P ADC, the MF may send the rendered digital human media to UE2 via RTP or ADC.

[0285] In this way, the first network side device can perform digital human media rendering for the first UE, so that the first UE and the second UE can smoothly conduct a digital human call, thereby improving the effect of the digital human call conducted in the digital human image.

[0286] FIG10 shows a flow chart of a digital human communication method provided in an embodiment of the present application. As shown in FIG10 , the digital human communication method may include the following step 301 .

[0287] Step 301: During the process of establishing an application data channel for digital human communication, the second UE obtains an eighth message.

[0290] First address information, the first address information is used to indicate the address for downloading the digital human image;

[0291] The second address information is used to indicate the address of the second network side device, and the second network device stores the first digital human image.

[0292] In some embodiments of the present application, the second UE may be a UE participating in digital human communication, which may be a peer UE of the first UE.

[0293] In some embodiments of the present application, the second UE can obtain the digital human image that performs digital human media rendering for the first UE by obtaining a message containing at least one of a digital human identifier, an address indicating downloading the digital human image, and an address indicating a second network side device.

[0294] In some embodiments of the present application, the eighth message may be carried in a re-invite message sent by the third network-side device.

[0316] The at least one digital human identification may include a first digital human identification.

[0317] In some embodiments of the present application, the third network device may send the first digital human identifier to the fourth network device. The fourth network device may then send the first digital human identifier to the second network device. Upon receiving the first digital human identifier, the second network device may return the first address information corresponding to the first digital human identifier to the fourth network device. The fourth network device may then return the first address information to the third network device. The third network device may carry the first address information in a ninth message and send it to the second UE.

[0318] In some embodiments of the present application, when the first information includes the first digital human identification and the second address information, the digital human communication method provided by the embodiment of the present application may further include the following step 305.

[0319] Step 305: The second UE obtains the first address information from the second network-side device, and downloads the digital human image based on the first address information.

[0320] The second network side device is used to provide first address information corresponding to the first digital human identifier.

[0321] In some embodiments of the present application, the “second UE obtains the first address information from the second network side device” in the above step 305 may include the following steps 305a and 305b.

[0322] Step 305a: The second UE sends a tenth message to the second network-side device, where the tenth message carries the first digital human identifier;

[0323] Step 305b: The second UE receives the eleventh message sent by the second network side device, where the eleventh message includes the first address information.

[0324] In some embodiments of the present application, when the eighth message includes the first digital human identifier and the address of the second network side device, the second UE can directly access the second network side device based on the address of the second network side device, and obtain the first address information from the second network side device based on the first digital human identifier.

[0325] In this way, when the first message contains at least one of the first digital human identifier and the second address information, the second UE can obtain the first address information corresponding to the first digital human identifier from the second network side device or the third network side device, and download the digital human image based on the first address information, thereby improving the flexibility of the first network side device in obtaining the first address information.

[0327] Step B: The second UE downloads the digital human image based on the first address information through the application data channel.

[0328] In some embodiments of the present application, after the application data channel is established, the second UE may download the digital human image based on the first address information through the application data channel.

[0329] In this way, the second UE can obtain the address information required to download the digital human image during the establishment of the application data channel, so that the digital human image can be downloaded immediately after the application data channel is established, thereby improving the efficiency of rendering for the first UE.

[0330] In some embodiments of the present application, before the above step 301, the digital human communication method provided by the embodiment of the present application may further include the following step 306.

[0331] Step 306: The second UE negotiates with the first UE and the first network-side device whether the second UE performs digital human media rendering for the first UE based on at least one of the capability information and power information of the first UE, at least one of the capability information and power information of the second UE, and the capability information of the first network-side device.

[0332] In some embodiments of the present application, the capability information and power information of the second UE can be used to indicate whether the second UE has the ability to render digital human media. The capability information of the second UE includes at least one of the following: computing power information, load information, and capability information for providing data channel services.

[0333] In some embodiments of the present application, the capability information and power information of the first UE are used to indicate whether the first UE has the ability to render digital human media, and the capability information of the first UE includes at least one of the following: computing power information, load information, and capability information for providing data channel services.

[0334] In some embodiments of the present application, when the second UE performs digital human media rendering for the first UE, the second UE and the first UE can negotiate whether the second UE performs digital human media rendering for the first UE based on at least one of the capability information and power information of the first UE, at least one of the capability information and power information of the second UE, and the capability information of the first network side device.

[0335] In this way, digital human media rendering can be performed for the first UE while ensuring that the second UE has the capability of performing digital human media rendering.

[0336] In some embodiments of the present application, the digital human communication method provided by the embodiments of the present application may further include the following step 307.

[0337] Step 307: After the application data channel is established, the second UE performs digital human media rendering.

[0338] In some embodiments of the present application, the second UE can obtain the address information required to download the digital human image during the establishment of the application data channel, so that after the application data channel is established, the digital human image can be immediately downloaded and the digital human media rendering can be performed, thereby improving the efficiency of rendering for the first UE.

[0339] In some embodiments of the present application, the digital human communication method provided by the embodiments of the present application may further include the following step 308.

[0340] Step 308: After the application data channel is established, the second UE receives the twelfth message sent by the first UE.

[0341] The twelfth message may include digital human-related data of the first UE.

[0342] In some embodiments of the present application, the digital human-related data of the above-mentioned first UE includes at least one of the following: gesture information of the user of the first UE, facial information of the user of the first UE, body movement information of the user of the first UE, and voice information of the user of the first UE.

[0344] Step 307a: The second UE performs digital human media rendering on the digital human image based on the digital human related data of the first UE.

[0345] In some embodiments of the present application, the first UE may send the captured character information of the user as digital human-related data to the second UE, so that the second UE may perform digital human media rendering on the digital human image based on the digital human-related data.

[0346] It is understandable that after the second UE obtains the digital human-related data, it performs digital human media rendering on the digital human image based on the digital human-related data. The rendered digital human media can have the same or similar expressions, actions, sounds and other features as the user of the first UE, thereby improving the effect of digital human communication.

[0347] In some embodiments of the present application, before the above step 308, the digital human communication method provided by the embodiment of the present application may further include the following step 309.

[0348] Step 309: The second UE sends a thirteenth message to the first UE. The thirteenth message is used to indicate that the downloading of the digital human image is completed.

[0349] In some embodiments of the present application, after the digital human image is downloaded, the second UE may send a thirteenth message to the first UE to notify the first UE that the digital human-related data may be sent to the second UE, so that the rendered digital human media has a better display effect.

[0350] The following takes the first UE as UE1, the second UE as UE2, the first network side device as MF, the second network side device as AR, the third network side device as IMS AS, the fourth network side device as DCSF, and the fifth network side device as IS-CSCF as an example to illustrate the digital human communication method provided in the embodiment of the present application.

[0355] S805-1. When the eighth message carries the first digital human identifier, the DCSF requests the AR for the digital human image.

[0356] In some embodiments of the present application, the request for the digital human image may carry the first digital human identifier.

[0357] S805-2. AR returns the first address information corresponding to the digital human image.

[0358] S807-S808. The IMS AS may send a re-invite message to the I / S-CSCF, and then the I / S-CSCF sends the re-invite message to UE2.

[0359] In some embodiments of the present application, the re-invite message may carry the eighth message or the first address information returned by the AR.

[0360] S809: When the eighth message carries at least the first address information, UE2 downloads the digital human image according to the first address information.

[0361] Exemplarily, when the eighth message carries at least the download URL corresponding to the first digital human identifier, UE2 can directly download the digital human image according to the download URL.

[0362] It should be noted that steps S805-1 and S805-2, and step S809 may be performed alternatively. That is, if the eighth message carries the first digital personal identifier, steps S805-1 and S805-2 may be performed, but step S809 may not be performed; if the eighth message carries at least the first address information, step S809 may be performed, but steps S805-1 and S805-2 may not be performed.

[0363] S820. UE1 obtains digital human related data used to generate a digital human image in digital human communication.

[0364] For example, UE1 may capture information such as actions, expressions, and sounds of the user of UE1.

[0365] S821. UE2 performs digital human media rendering.

[0366] S822. UE2 displays the digital human image of UE1.

[0367] In this way, the second UE can obtain at least one of the digital human identification, the address indicating the downloading of the digital human image, and the address indicating the second network side device during the establishment of the application data channel for digital human communication, so as to perform digital human media rendering for the first UE to improve the effect of digital human communication.

[0368] Example 4: As shown in FIG12 , the digital human communication method provided in the embodiment of the present application includes the following steps:

[0369] S903: After the ADC is established, UE1 provides UE2 with a download URL for the digital human image through a data channel.

[0370] In some embodiments of the present application, UE1 may select a digital human image and determine a digital human identifier corresponding to the digital human image during the BDC process.

[0371] S904. UE2 downloads the digital human image through the download URL.

[0372] S905 , UE2 sends a digital human image download completion message to UE1.

[0373] S906. UE1 sends the digital human related data of UE1 to UE2.

[0374] S907 , UE2 performs digital human media rendering on the digital human image based on the digital human related data of UE1.

[0375] S908. UE2 displays the rendered digital human image.

[0376] In this way, the second UE can perform digital human media rendering for the first UE, so that the first UE and the second UE can smoothly conduct a digital human conversation, thereby improving the effect of the digital human conversation conducted in the digital human image.
