1. A cell selection method, comprising:
determining, by a terminal device, candidate measurement frequencies according to geographical location information, satellite orbit information of one or more satellites in a service area where the terminal device is located, and a correspondence between the satellite orbit information and frequency bands used by the one or more satellites; wherein the geographical location information is for indicating geographical location coordinates where the terminal device is currently located, and the satellite orbit information comprises orbital data information and/or identification information of the one or more satellites;
performing, by the terminal device, a cell measurement on the candidate measurement frequencies to obtain measurement results; and
selecting or re-selecting, by the terminal device, a target cell which meets a first preset condition based on a measurement result meeting the first preset condition in the measurement results.
