Disclosed is a method for transmitting downlink data in a wireless communication system, and a device for same. Specifically, disclosed is a method for transmitting downlink data to a UE in a wireless communication system, the method comprising: a mobility management entity (MME) receiving a downlink data notification message from a serving gateway (S-GW); and, if the MME has detected that a UE is in a sleep state, the MME transmitting, to the S-GW, a response message for instructing the buffering of the downlink data, wherein the response message comprises the downlink data buffering time, and the buffering time may be a time at which the conversion of the UE from the sleep state to a reachable state is expected. |
