Machine-type communication (MTC) method and device

The embodiment of the invention provides a machine-type communication (MTC) method and device. The method comprises the following steps: receiving a first inquiry request sent by an MTC server communicated with user equipment (UE); determining an MTC-IWF (Machine-Type Communication Interworking Function) entity communicated with the UE according to the load state of the MTC-IWF entity and/or the location information of the UE; and sending a first inquiry response to the MTC server, wherein the first inquiry response carries an identifier of the MTC-IWF entity communicated with the UE in order to communicate the MTC server with the MTC-IWF entity communicated with the UE according to the identifier of the MTC-IWF entity. By adopting the method provided by the embodiment, the MTC-IWF entity communicated with the UE is determined according to the load state of the MTC-IWF entity and/or the location information of the UE, so that network resources are allocated reasonably, and the utilization ratio of an entire network is increased.
