This application discloses a communication method, including: An access network device generates a candidate conditional handover configuration group, and sends the candidate conditional handover configuration group to a terminal, where the candidate conditional handover configuration group includes one or more candidate conditional handover configurations, and the one or more candidate conditional handover configurations correspond to a flight-related parameter of the terminal; and the terminal obtains a current flight parameter, and determines a target conditional handover configuration from the candidate conditional handover configuration group based on the current flight parameter, where the target conditional handover configuration is used to determine a second cell that the terminal expects to access. In this process, because the candidate conditional handover configuration group generated by the access network device to which a first cell belongs corresponds to the flight-related parameter, the terminal obtains the target conditional handover configuration in the candidate conditional handover configuration group based on a matching result between the current flight parameter and the flight-related parameter. In this way, accuracy of obtaining the target conditional handover configuration is improved, and efficiency of handover to the second cell is improved.
