A machine type communication scheduling method, comprising: sending, by a base station, first downlink control information to a target user equipment in an air-interface idle mode in a serving cell of the base station, wherein the first downlink control information comprises a first resource indicator corresponding to a first identifier of the target user equipment, the first identifier is an identifier used by the base station for scheduling the target user equipment when the target user equipment is in the air-interface idle mode, the first resource indicator is used to indicate a resource used by the target user equipment during resource scheduling, and the resource comprises a downlink resource; and sending, by the base station, a first data packet to the target user equipment by using the downlink resource; wherein the first identifier is an identifier of a preset type; and characterized in that the first data packet comprises a correspondence between a second identifier and a third identifier of the target user equipment, so that the target user equipment obtains the second identifier according to the third identifier of the target user equipment after receiving the first data packet; the second identifier is an identifier that is newly allocated by the base station to the target user equipment in the air-interface idle mode and that is used for entering an air-interface connected mode by the target user equipment; and the third identifier is used to identify the target user equipment between the target user equipment and a core network device; wherein the first identifier of the target user equipment is a Paging-Radio Network Temporary Identity, P-RNTI, of the target user equipment calculated by the base station and the target user equipment according to a preset rule; the second identifier of the target user equipment is a Cell-Radio Network Temporary Identity, C-RNTI, of the target user equipment allocated by the base station to the target user equipment; and the third identifier of the target user equipment is a Temporary Logical Link Identifier, TLLI or an International Mobile Subscriber Identity, IMSI, of the target user equipment. sending, by a base station, first downlink control information to a target user equipment in an air-interface idle mode in a serving cell of the base station, wherein the first downlink control information comprises a first resource indicator corresponding to a first identifier of the target user equipment, the first identifier is an identifier used by the base station for scheduling the target user equipment when the target user equipment is in the air-interface idle mode, the first resource indicator is used to indicate a resource used by the target user equipment during resource scheduling, and the resource comprises a downlink resource; and sending, by the base station, a first data packet to the target user equipment by using the downlink resource; wherein the first identifier is an identifier of a preset type; and characterized in that the first data packet comprises a correspondence between a second identifier and a third identifier of the target user equipment, so that the target user equipment obtains the second identifier according to the third identifier of the target user equipment after receiving the first data packet; the second identifier is an identifier that is newly allocated by the base station to the target user equipment in the air-interface idle mode and that is used for entering an air-interface connected mode by the target user equipment; and the third identifier is used to identify the target user equipment between the target user equipment and a core network device; wherein the first identifier of the target user equipment is a Paging-Radio Network Temporary Identity, P-RNTI, of the target user equipment calculated by the base station and the target user equipment according to a preset rule; the second identifier of the target user equipment is a Cell-Radio Network Temporary Identity, C-RNTI, of the target user equipment allocated by the base station to the target user equipment; and the third identifier of the target user equipment is a Temporary Logical Link Identifier, TLLI or an International Mobile Subscriber Identity, IMSI, of the target user equipment.
