Abstract: A wireless communication system is disclosed. More particularly, a control method and device based on multiple priorities in a wireless communication system is disclosed. The method for controlling a back-off timer in a terminal configured with multiple non-access stratum, NAS, signaling priorities, comprises checking if a back-off timer runs due to a rejection of a first request message having a first NAS signaling priority level; and transmitting a second request message without a NAS signaling priority level to a network, when the back-off timer runs due to the rejection, wherein the transmission of the second request message is performed without stopping the back-off timer.

Abstract: Disclosed are a method and apparatus for transmitting downlink data in a wireless communication system. More specifically, a method for transmitting downlink data to a user equipment (UE) in a wireless communication system comprises receiving, by a Mobile Management Entity (MME), a Downlink Data Notification message from a Serving Gateway (S-GW); and in case the MME detects that a UE is in a sleep mode, transmitting, by the MME, a response message for indicating buffering of downlink data to the S-GW, wherein the response message includes buffering time of the downlink data, and the buffering time is a time period until the UE is expected to switch from the sleep mode to a reachable state.
