Abstract: A method for moving user equipment (UE) from a next generation system (NGS) to an evolved packet system (EPS) in a wireless communication system comprises: by the UE, a step of determining to move to the EPS; and a step of transmitting a radio resource control (RRC) connection request and an attach request to the EPS. In the method for moving from the NGS to the EPS, if the UE has an ongoing voice call when determining to move to the EPS, the UE maintains the ongoing voice call by performing at least one of an access class barring (ACB) execution or a transmission of ongoing voice call related information by using “ongoing voice call” call type information.

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: 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: 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.
