The present invention relates to the technical field of wireless communications. Disclosed are a paging method, device and system. A message is sent to user equipments according to coverage levels of the user equipments, so that the user equipments in different coverage areas obtain the paging message, and the number of retransmissions of the paging message is reduced. The method provided in the present invention comprises: a base station receives a paging message of a machine-to-machine user equipment; calculate a paging position of the user equipment; determine a coverage level of the user equipment; and send an air interface paging message to the user equipment according to the coverage level of the user equipment, and send paging scheduling information at the paging position, the paging scheduling information being used for indicating a sending position of the air interface paging message, and the air interface paging message containing the paging message of the user equipment.
