A cell measurement method includes: when a cell measurement result satisfies a reporting condition, sending a measurement report to a source base station, the measurement report includes first core network type information of n respective neighbor cells for user equipment (UE), where n is a positive integer. The first core network type information indicates at least one of: a type of a core network accessed by a base station to which a respective neighbor cell belongs, or an identifier of a network slice supported by a base station to which a respective neighbor cell belongs. It can therefore be ensured that the UE is capable of work normally after handover.
