摘要： 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.

摘要： A co-cable probability detection method, including obtaining information about at least two first events and at least two second events, where the information about the at least two first events is obtained based on a first sounding signal in a first transmission medium, the information about the at least two second events is obtained based on a second sounding signal in a second transmission medium, the information about the first events indicates at least one cable segment on the first transmission medium, and the information about the second events indicates at least one cable segment on the second transmission medium, and obtaining, based on the information about the first events and the second events, a probability that the at least one cable segment on the first transmission medium and the at least one cable segment on the second transmission medium comprise a co-cable segment.
