determining a first target cell based on the conditional handover configuration information, wherein determining the first target cell comprises:
receiving a handover message from the first network device in a process of determining the first target cell, wherein the handover message comprises an identifier of a second target cell and a dedicated random access resource required for accessing the second target cell, and the dedicated random access resource comprises a preamble index and a time-frequency resource;
stopping determining the first target cell based on the conditional handover configuration information, and performing contention-free random access to the second target cell based on the dedicated random access resource; and
