This application relates to the field of communications technologies, and provides a cell handover method and an apparatus in a high-speed movement scenario, to resolve problems of a relatively high service drop rate and a relatively high re-establishment rate of a terminal device in the high-speed movement scenario. The method includes: enabling a high-speed railway function of a terminal device; obtaining path information; determining a first target cell based on the path information; and reporting a first measurement report when a measurement value of a source cell meets a second threshold, where the first measurement report is used to trigger a network side device to control the terminal device to hand over from the source cell to the first target cell, and the source cell is a cell on which the terminal device camps, the second threshold is greater than a first threshold, and the first threshold is a threshold that is indicated by the network side device and that is used to trigger the terminal device to report a measurement report.
