1. A handover processing method, comprising:
sending a conditional handover (CHO) command indicating a first cell identifier and a plurality of second cell identifiers; and
sending a handover command to a user equipment (UE) before determining that the UE performs handover based on the CHO command;
wherein the handover command indicates a first cell identified by the first cell identifier and duration information comprising a plurality of time ranges, each of which corresponds to each of the plurality of second cell identifiers; wherein the first cell identified by the first cell identifier comprises a first handover target cell, and a plurality of second cells respectively identified by the plurality of second cell identifiers comprises a second handover target cell to which the UE is capable of accessing after the UE fails to be handed over to the first handover target cell indicated in the handover command,
wherein the duration information is configured to indicate a second time range of the plurality of time ranges corresponding to the second handover target cell, and
wherein in response to the UE fails to be handover to the first handover target cell, the second time range of the duration information is used for the UE to select the second handover target cell identified by a corresponding second cell identifier from the plurality of second cell identifier indicated by the CHO command and to be handed over to the second handover target cell.
