Abstract: 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.

Abstract: A caller identification display method includes a terminal device sending a first request to a server of a first application, where the first request is used by the terminal device to subscribe to a first service. After receiving the request sent by the terminal device, the server of the first application sends a first response to the terminal device. The server of the first application sends a first number to the terminal device. The terminal device obtains an association relationship between the first number and the first application. When the terminal device makes a call or receives an incoming call, the terminal device displays a first call interface, where the first call interface includes prompt information, and where the prompt information includes the association relationship between the first number and the first application.

Abstract: This application provides a cell selection method, a cell reselection method, and a chip, to improve user experience. The cell selection method includes: A terminal device searches for a first candidate cell, and receives a system message of the first candidate cell, where the system message includes parameter information of the first candidate cell and bandwidth information of the first candidate cell, and the bandwidth information is used to indicate a bandwidth of the first candidate cell. The terminal device determines a cell selection reception level value Srxlev and a cell selection quality value Squal of the first candidate cell based on cell measurement values and the parameter information of the first candidate cell, and determines that Srxlev>0 and Squal>0. When the bandwidth of the first candidate cell is greater than a preset threshold, the terminal device camps on the first candidate cell.
