Provided in the present application are a cell reselection method and apparatus based on a slice, and a device and a storage medium. The method comprises: a network device transmitting, to a terminal device, slice-related information that is associated with a serving cell frequency point and/or slice information that is associated with at least one neighboring cell frequency point; and the terminal device determining a final target reselected cell on the basis of the slice-related information that is associated with the serving cell frequency point and/or the slice information that is associated with the at least one neighboring cell frequency point.
