1. A positioning method, implemented in a positioning device, the method comprising:
acquiring configuration information from a ranging data frame structure, wherein the configuration information comprises a time offset, and the time offsets of at least two different positioning devices differ from one another;
determining a time domain position of a first time unit in the ranging data frame according to the time offset; and
sending a ranging message on the first time unit to a plurality of anchor devices within a preset range of the device, the ranging message being used by a server to determine a position of the positioning device according to differences in times at which each of the plurality of anchor devices received the ranging message,
wherein
the first time unit occurs in the frame structure according to a predetermined cycle, and the predetermined cycle is determined by the type of the positioning device,
the type of the positioning device comprises: a mobile device type and a fixed device type, and
the predetermined cycle corresponding to the mobile device type is less than that corresponding to the fixed device type.
