Abstract: A method for transmitting buffered data of an MME comprises the steps of: performing a CP mode; buffering downlink data, when the downlink data on a terminal is received from an S-GW, during an idle period in which an ECM-idle state of the terminal is maintained; receiving, from the terminal, a service request message for requesting a UP mode; transmitting, to a base station, an initial context setup request message for setting a DRB, and receiving, from the base station, an initial context setup completion message; and transmitting, to the S-GW, a modified bearer request message for setting an S1 bearer between the base station and the S-GW, wherein the buffered data is included in the initial context setup request message and may be transmitted to the base station.

Abstract: When a non-access stratum (NAS) message is generated in an NAS layer of a user equipment, the NAS layer transfers the NAS message and type information to an access stratum (AS) layer of the user equipment. An AS message containing the NAS message is transmitted to a network. The type information indicates whether the NAS message is a first type message containing user data or a second type message without user data.

Abstract: Disclosed are a method for performing V2X communication in a wireless communication system and an apparatus for the same. Specifically, a method for performing vehicle-to-everything (V2X) communication by a user equipment (UE) in a wireless communication system includes: receiving a transmission request of a V2X message of a V2X service identified by a V2X service identifier from an upper layer by using V2X communication through a PC5 interface, the transmission request including the V2X message and the V2X service identifier; requesting or selecting a resource for the V2X communication through the PC5 interface to a base station based on whether the UE is serviced by an evolved universal terrestrial radio access network (E-UTRAN) for the V2X communication; and transmitting the V2X message through the PC5 interface by transferring the V2X me3ssage to a lower layer, and when mapping between the V2X service identifier and a transmission parameter is configured, the transmission parameter associated with the V2X service identifier may be transferred to the lower layer together with the V2X message.

Abstract: When a specific case occurs, user equipment can initiate a tracking area update (TAU) step by transmitting a TAU request. If the user equipment is using a control plane connection for the transport of user data when a radio resource control (RRC) connection failure occurs and there is no pending signaling or uplink user data, the specific case can be applied to a case in which it is indicated, to a network, that downlink data reception subsequent to the uplink data transmission is predicted.

Abstract: A network node of the present invention transmits downlink data for user equipment using a paging message. The user equipment can transmit to the network node a radio resource control (RRC) connection request message including acknowledgement information that indicates acknowledgement of the downlink data if the paging message contains the downlink data for the user equipment. The network node can transmit to the user equipment an RRC connection refusal message including information that indicates confirmation with respect to the acknowledgement information if the paging message contains the downlink data for the user equipment and the RRC connection request message contains the acknowledgement information.
