Positioning method, device, and system, and storage medium

A positioning method, applied to a second server, comprising:

• receiving a differential data request sent by a first server, the differential data request comprising first location information, and the first location information comprising an identity of a terminal;
• determining differential data of the terminal according to the differential data request;
• and
• sending the differential data to the first server,
• wherein the method further comprises:
• receiving a target message sent by the first server, the target message comprising the identity of the terminal, terminal type information and second location information, so that the second server stores the target message.

A positioning apparatus, applied to a second server, comprising a processor and a memory configured to store instructions executable by the processor,

• wherein when the instructions are executed by the processor, the processor is configured to cause the positioning apparatus to perform:
• receiving a differential data request sent by a first server, the differential data request comprising first location information, and the first location information comprising an identity of a terminal;
• determining differential data of the terminal according to the differential data request;
• and
• sending the differential data to the first server,
• wherein the processor is further configured to cause the positioning apparatus to perform:
• receiving a target message sent by the first server, the target message comprising the identity of the terminal, terminal type information and second location information, so that the second server stores the target message.
