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.

Abstract: A multi-cell/multicast coordination entity (MCE) determines a cluster to which a vehicle-to-everything (V2X) message. The MCE receives a first session start message, which includes a temporary mobile group identity (TMGI), quality of services (QoS) parameters, and a list of cells, from a V2X application server and determines a cluster, which contains group of cells, to which V2X message is to be broadcast, based on the received TMGI, QoS parameters, and list of cells. Upon determining the cluster, the MCE transmits a second session start message, which includes an indication to notify eNodeB (eNB) to wait for scheduling information, to eNBs corresponding to the determined cluster, and transmits MBMS scheduling information to the eNBs. Further, update of the cluster may be triggered from the V2X application server or from the eNB with limited feedback.

Abstract: The present invention establishes a plurality of packet data network (PDN) connections in a user apparatus by coordinated selected IP traffic offload (CSIPTO). The present invention achieves this by receiving, from a network entity responsible for a control plane, an indication for a gateway rearrangement arising from CSIPTO. A determination is then made as to whether to maintain a previously established first PDN connection on the basis of the indication and establishing a second PDN connection on the basis of the indication. Then, if the previously established first PDN connection is to be maintained, marking one or both of the first PDN connection and the second PDN connection.

Abstract: A disclosure of the present specification provides a method for establishing a packer data network (PDN) connection by a user equipment (UE). The method may comprise the steps of: transmitting a session initiation protocol (SIP)-based request message for requesting sending of a voice over LTE (VoLTE) call through a first type PDN connection; receiving, from a network node, a message including information directly or indirectly indicating that there is a problem in the first type PDN connection, instead of a normal response message to the SIP-based request message; determining to change the PDN type from the first type to a second type, on the basis of the information in the received message; and transmitting, to a mobility management entity (MME), a PDN connection request message including information on the changed second type.

Abstract: One disclosure of the present specification provides a method by which a network entity, which controls a control plane, determines whether to offload traffic of a user equipment (UE) to a wireless local area network (WLAN). The method can comprise a step of acquiring subscriber information on the UE from a subscriber information server, wherein the subscriber information can include a WLAN offloadability indication for a specific packet data network (PDN) connection. The method can comprise the steps of: determining WLAN offloadability for the specific PDN connection on the basis of the WLAN offloadability indication and configuration information; transmitting the WLAN offloadability indication to network nodes according to the determination; and transmitting the WLAN offloadability indication to the UE according to the determination.

Abstract: One disclosure of the present specification provides a method for performing a multimedia telephony (MMTEL) service in a machine type communication (MTC) device. The method can comprise the steps of: receiving, from an upper layer, an indication in which a mobile orienting (MO) MMTEL service is initiated; setting a special call type for the MMTEL service in a call type field within a request message for performing the MMTEL service; and transmitting the request message to a lower layer, wherein, when the request message is transmitted to the lower layer, if the MMTEL service is initiated, the MTC device does not transmit an extended access barring (EAB) application indication to the lower layer or can transmit, to the lower layer, an indication commanding the EAB to be skipped, even if the EAB is set.
