Abstract: The present disclosure provides a method for receiving a paging message, by a user equipment (UE) in a radio resource control (RRC) connection suspended state, in a wireless communication system. The method includes receiving the paging message from an evolved Node B (eNB); checking an indicator indicating whether the eNB stores a UE context, wherein the indicator is included in the paging message; and transmitting an RRC connection-resume request message or an RRC connection request message to the eNB based on the indicator.

Abstract: The present specification proposes a method for receiving system information by a user equipment (UE) configured with an extended discontinuous reception (eDRX) in a wireless communication system. Specifically, the method includes the step of receiving a paging message including an indicator indicating system information modification in a modification period within an active time of the eDRX; determining whether to receive the system information by comparing the active time with the modification period; and receiving the system information in a next modification period when it is determined to receive the system information.
