Disclosed is a method for applying an extended access barring (EAB), the method performed by a machine type communication (MTC) device and comprising: recognizing, by an upper layer of the MTC device, a change from being operated in an override low priority to being operated in a low priority; informing, by the upper layer, a lower layer that the priority has been changed; and determining, by the lower layer, whether to apply the EAB, to handle at least one of an attach request, a tracking area update request, and a service request. If the EAB is applied, a RRC connection is barred.
