The method includes: receiving, by user equipment, an area identifier and a corresponding layering type, where the layering type is a capacity-oriented type or a coverage-oriented type; if an area currently accessed by the user equipment is a capacity-oriented area, switching, by the user equipment, to a coverage-oriented area based on the layering type when changing to an idle state; and receiving a paging message for the coverage-oriented area. Alternatively, the method includes: determining, by a network device, a coverage-oriented area in a registration area of user equipment based on an area identifier and a corresponding layering type, and paging the user equipment in the coverage-oriented area. According to the present invention, based on the layering type, switching to a coverage-oriented area is implemented on a user equipment side, and paging in the coverage-oriented area is implemented on a network side, so that paging overheads of a base station and a network device are reduced, and radio resources are saved.
