Specifically, after obtaining the configuration information, the terminal device measures the first measurement object. If a measurement result of a candidate target cell corresponding to the measurement object satisfies the trigger condition of the handover, the terminal device may determine the candidate target cell as the first target cell. After determining the first target cell, the terminal device may perform a handover, that is, is handed over from the serving cell to the first target cell.
It should be understood that when a plurality of candidate target cells all satisfy the trigger condition, the terminal device may select one of the candidate target cells as the first target cell. Specifically, the terminal device may randomly select one of the candidate target cells as the first target cell, or the terminal device may select, according to a rule, the first target cell from the plurality of candidate target cells that satisfy the trigger condition. This is not limited in this embodiment of this application.
In this embodiment of this application, the measurement object may be frequency information, for example, may be a frequency. Specifically, the frequency includes an SSB frequency (for example, absoluteFrequencySSB) and/or an absolute frequency position (for example, absoluteFrequencyPointA) of a reference resource block (common RBo). This application is not limited thereto. The first measurement object may be a frequency. The terminal device may measure signal quality of a plurality of candidate target cells corresponding to the frequency. When measured signal quality of a candidate target cell satisfies the trigger condition of the handover, the terminal device may determine the candidate target cell as the first target cell.
