User positioning method, information push method, and related apparatus

A server, comprising:

• one or more processors and one or more non-transitory computer-readable memories coupled to the one or more processors and configured with instructions executable by the one or more processors to cause the server to perform operations comprising:
• receiving an identification information obtaining request from an audio signal playing terminal associated with an object;
• allocating the identification information to the object associated with the audio signal playing terminal in response to the identification information obtaining request;
• receiving an audio signal having a watermark from a client terminal, wherein the watermark indicates the identification information of the object, and wherein the audio signal is obtained by the client terminal from the audio signal playing terminal associated with the object;
• parsing the audio signal to obtain the identification information indicated by the watermark;
• determining a position of the object based on the obtained identification information;
• and
• determining a position of the client terminal based on the position of the object.

A audio signal playing terminal, comprising:

• one or more processors and one or more non-transitory computer-readable memories coupled to the one or more processors and configured with instructions executable by the one or more processors to cause the audio signal playing terminal to perform operations comprising:
• obtaining, by the audio signal playing terminal, identification information of an object associated with the audio signal playing terminal, by;
• sending, by the audio signal playing terminal, an identification information obtaining request to a server, and
• receiving the identification information that is allocated to the object associated with the audio signal playing terminal by the server in response to the identification information obtaining request;
• watermarking, by the audio signal playing terminal, a to-be-played audio signal based on the identification information to obtain an audio signal having a watermark;
• and
• playing, by the audio signal playing terminal, the audio signal having the watermark for a client terminal to collect the audio signal having the watermark and send the audio signal having the watermark or the identification information to the server to enable the server to obtain the identification information and determine a position of the object based on a correspondence between the identification information and the position of the object and thereby to determine a position of the client terminal.
