Abstract: Provided is a tracking area assignment method by an access and mobility management function (AMF) in a wireless communication system. The method may include receiving, from a session management function (SMF), service and session continuity (SSC) mode indication information for a protocol data unit (PDU) session generated for a user equipment (UE), obtaining serving area information for a serving area of a serving user plane function (UPF) associated with the PDU session, determining the assignment of a new tracking area to the UE is necessary based on a tracking area pre-assigned to the UE and the serving area, and performing tracking area update for the assignment of the new tracking area to the UE if it is determined that the assignment of the new tracking area is necessary.

Abstract: A method and apparatus for performing application specific congestion control for data communication (ACDC) in a wireless communication system is provided. A radio resource control (RRC) layer of a user equipment (UE) receives ACDC barring information for a plurality of ACDC categories via system information from a network, determines whether the ACDC barring information for the plurality of ACDC categories contains ACDC barring information for a specific ACDC category selected by upper layers, and if it is determined that the ACDC barring information for the plurality of ACDC categories does not contain ACDC barring information for a specific ACDC category selected by upper layers, performs ACDC barring check by using ACDC barring information for last ACDC category among the plurality of ACDC categories.

Abstract: A network may instruct to change the connection of a user equipment connected to the network in a first mode, to a second mode. The network may instruct re-establishment while instructing the user equipment to change the connection. In this case, the network and the user equipment release the connection of the first mode while maintaining an uplink resource allocated to the user equipment. After completing the connection release, the user equipment may transmit a connection request to the network using the uplink resource directly without any access process.

Abstract: One embodiment of the present specification provides a method for responding to a failure of a specific packet data network (PDN) in user equipment (UE). The method can comprise the steps of: receiving information on whether a specific PDN has a failure; determining whether the specific PDN is in a failure state on the basis of the received information; and if it is determined that the specific PDN is in the failure state, performing a detach procedure for the specific PDN or a disconnection procedure for the specific PDN, and then, performing an attach procedure to another PDN or a PDN connection establishment procedure.

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: A method of supporting data transmission of a network node in a wireless communication system includes: receiving downlink data from a Data Network (DN); encapsulating the downlink data with an IP address of an User Equipment (UE) based on whether the DN is an Internet Protocol (IP) based network or a non-IP based network; not encapsulating, if the DN is the IP based network, the received downlink data with the IP address of the UE and encapsulating, if the DN is the non-IP based network, the received downlink data with the IP address of the UE; and transmitting the downlink data encapsulated with the IP address or the downlink data that are not encapsulated with the IP address to an Access Network (AN).

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.
