[0067] The digital human determination method provided in the embodiment of the present application can be applied in the application environment as shown in FIG. 1 . The DCSF network element 102, MF 103 and terminal 104 communicate through the network. The DCSF network element obtains the digital human download request initiated by the terminal to enable the DCSF network element to feedback the digital human information of the candidate digital human corresponding to the terminal identity to the terminal, so that the terminal determines the target digital human from the candidate digital human according to the digital human information.

[0069] S201, obtaining a digital human download request initiated by a terminal.

[0070] The digital human download request carries the terminal identity of the terminal.

[0071] It should be noted that the digital human download request is used to inform the DCSF network element to perform the operation of feeding back the digital human information of the candidate digital human corresponding to the terminal identity to the terminal, so as to ensure that the subsequent terminal can successfully determine the target digital human, thereby completing the image download and image rendering operations for the target digital human, and completing the execution of the digital human service.

[0072] S202, feeding back digital human information of candidate digital humans corresponding to the terminal identity to the terminal, so that the terminal determines a target digital human from the candidate digital humans according to the digital human information.

[0073] The digital person information includes the digital person identification of the candidate digital person and the identification of the candidate application program that has the permission to use the candidate digital person.

[0074] It should be noted that before the digital human information of the candidate digital human corresponding to the terminal identity identifier is fed back to the terminal, the terminal can be authenticated based on the terminal identity identifier of the terminal in the digital human download request to verify whether the terminal has the authority to use the digital human. Furthermore, if the terminal has the authority to use the digital human, the digital human information of the candidate digital human corresponding to the terminal identity identifier is fed back to the terminal so that the terminal can determine the target digital human from the candidate digital humans based on the digital human information.

[0075] Specifically, when the terminal is verified for authority based on the terminal identity identifier of the terminal in the digital person download request, it can be verified whether the terminal identity identifier of the terminal belongs to the terminal identity whitelist that has pre-completed the digital person account opening; wherein, the terminal identity whitelist stores at least one candidate identity identifier, and the terminals corresponding to each candidate identifier have completed the digital person account opening operation, that is, they all have the right to use the digital person; therefore, if the terminal identity identifier of the terminal belongs to the terminal identity whitelist, it is determined that the terminal has the right to use the digital person, and the operation of feeding back the digital person information of the candidate digital person corresponding to the terminal identity identifier to the terminal can be executed; if the terminal identity identifier of the terminal does not belong to the terminal identity whitelist, it is determined that the terminal does not have the right to use the digital person, and the operation of feeding back the digital person information of the candidate digital person corresponding to the terminal identity identifier to the terminal cannot be executed.

[0076] In the above-mentioned digital person determination method, the DCSF network element obtains the digital person download request initiated by the terminal to enable the DCSF network element to feedback the digital person information of the candidate digital person corresponding to the terminal identity to the terminal, so that the terminal can determine the target digital person from the candidate digital person according to the digital person information.

[0079] Furthermore, when the DCSF network element sends the digital human information of the candidate digital human corresponding to the terminal identity to the media gateway MF connected to the terminal, in order to ensure that the digital human information can be sent to the terminal smoothly, it is necessary to verify whether the BDC between the terminal and the MF is established. If so, the digital human information sending operation is performed. Specifically, when the BDC between the terminal and the MF is successfully established, the digital human information of the candidate digital human corresponding to the terminal identity is sent to the media gateway MF connected to the terminal.

[0080] In one embodiment of the present application, when the terminal determines the target digital person from the candidate digital persons based on the digital person information, in order to ensure that the user can more intuitively know the digital person he wants to select through the terminal, the digital person information can be limited to also include the digital person thumbnail corresponding to the candidate digital person. Then, after the terminal obtains the digital person information of the candidate digital person, it can display the digital person thumbnail to the user through the terminal based on the digital person information of the candidate digital person, so that the user can more intuitively know the digital person he wants to select.

[0081] The above-mentioned digital human determination method, by successfully establishing the BDC between the terminal and the MF, realizes sending the digital human information of the candidate digital human corresponding to the terminal identity to the media gateway MF connected to the terminal, so that the MF can feedback the digital human information of the candidate digital human corresponding to the terminal identity to the terminal through the guided data channel BDC between the terminal and the MF, thereby ensuring that the terminal can successfully obtain the digital human information and preventing the subsequent process from being affected.
