Abstract: A method and an apparatus for determining a terminal device in close contact with another terminal device are provided. The method includes: A first network element obtains data of a plurality of terminal devices and an identifier of a first terminal device. The first network element determines, based on the data of the plurality of terminal devices, movement analysis results respectively corresponding to the plurality of terminal devices. The movement analysis results respectively corresponding to the plurality of terminal devices include a movement analysis result of the first terminal device. The first network element determines at least one second terminal device based on the movement analysis results respectively corresponding to the plurality of terminal devices. A movement track of the second terminal device overlaps a movement track of the first terminal device, a movement manner of the second terminal device is the same as a movement manner of the first terminal device on an overlapping movement track, and at least one preset event experienced by the second terminal device is the same as a preset event experienced by the first terminal device on the overlapping movement track. In the foregoing method, a close contact can be accurately located.

Abstract: In a network handover method disclosed in this application, when an electronic device accesses a first mobile network by using the first SIM card, the electronic device obtains network information of the first mobile network in a process in which the electronic device moves along a first route. When the electronic device predicts, according to the obtained network information of the first mobile network, that an exception is going to occur in the first mobile network, the electronic device accesses the second mobile network by using the second SIM card. In this technical solution, an electronic device having a dual SIM card can be handed over from a first mobile network to a second mobile network in advance when it is predicted that an exception is going to occur in the first mobile network, thereby reducing the possibility of frame freezing or network disconnecting when a user accesses the Internet.
