1. A cell reselection method, comprising:
receiving, by a terminal device, cell reselection information from a radio access network device, wherein the cell reselection information comprises an identifier of at least one carrier frequency, an identifier of a network slice supported by each of the at least one carrier frequency, and priority information of one carrier frequency corresponding to the identifier of the network slice, wherein the identifier of the network slice is information of a specific service type of the network slice or a network slice set identifier corresponding to the network slice; and
in response to the terminal device performing cell reselection, selecting, by the terminal device a cell on a carrier frequency of the network slice supported by the terminal device as a reselected to-be-camped cell based on the identifier of the at least one carrier frequency, the identifier of the network slice supported by each of the at least one carrier frequency, and the priority information of the one carrier frequency corresponding to the identifier of the network slice.
