Abstract: User equipment provides, to a network device, reference paging information generated according to a moving speed of the user equipment. The reference paging information is used by the network device to determine a paging area for sending a paging message. The network device receives the reference paging information generated by the user equipment according to the moving speed of the user equipment. The network device determines, according to the reference paging information, a paging area for sending a paging message to the user equipment. The network device sends, in the paging area, the paging message to the user equipment. The network device can determine the paging area according to the reference paging information, so that a paging resource waste in a paging process is reduced, relatively accurate paging is implemented, overheads of inter-network interfaces and air interfaces are greatly reduced, and system efficiency and stability are improved.
