1. A method for determining a terminal device in close contact with another terminal device, comprising:
obtaining, by a first network element, data of a plurality of terminal devices;
obtaining, by the first network element, an identifier of a first terminal device;
determining, by the first network element based on the data of the plurality of terminal devices, movement analysis results respectively corresponding to the plurality of terminal devices, wherein the data of the plurality of terminal devices comprises historical movement data of the first terminal device, the movement analysis results comprise a movement analysis result of the first terminal device, and the movement analysis result of the first terminal device comprises a movement track of the first terminal device, a start time and an end time corresponding to the movement track, a movement manner of the first terminal device on the movement track, and an event experienced by the first terminal device on the movement track; and
determining, by the first network element, at least one second terminal device based on the movement analysis results, wherein a movement track of the second terminal device overlaps the movement track of the first terminal device, a movement manner of the second terminal device is the same as the movement manner of the first terminal device on an overlapping movement track, and an event experienced by the second terminal device is the same as the event experienced by the first terminal device on the overlapping movement track.
