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: 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 invention provides a method for selecting an enhanced packet data gateway (ePDG). The method may be performed by a user equipment (UE) and comprise: determining, by the UE which has roamed from a home public land mobile network (H-PLMN) to a visited public land mobile network (V-PLMN), whether there exists an indication for selecting ePDG in the V-PLMN; determining, by the UE, whether the UE has attached to any PLMN in the V-PLMN, when it is determined that there exists the indication; determining, by the UE, whether there exists an ePDG PLMN list for the any PLMN in the V-PLMN, when it is determined that the UE has attached to the any PLMN; and selecting, by the UE, at least one ePDG in the ePDG PLMN list.

Abstract: A method is disclosed for managing a connection of an UE for transmitting and receiving a V2X message of a first network node in a wireless communication system, the connection management method including the steps of: allowing a first network node to determine that an UE for performing only a PC5 operation will be maintained in the ECM CONNECTED state; and allowing the first network node to transmit information requesting the release of a part of a packet data network (PDN) connection, to a second network node, after the determination.

Abstract: A method for discarding at least one packet by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of storing the at least one packet received from an upper layer in a buffer; determining whether or not a number of packets in the buffer is equal to or greater than a threshold value; and discarding the at least one packet from the buffer when the number of packets in the buffer is equal to or greater than the threshold value.

Abstract: One disclosure of the present specification provides a method for a terminal creating a session, the terminal supporting next-generation mobile communication. The method may comprise the steps of: determining that a session must be newly created if the creation of a session is not included in a process of attaching to a core network of a next-generation mobile communication; on the basis of service type information, determining that the session being newly created needs to be always-on, or in other words, always-connected; and transmitting, to a control plane (CP) function node for managing the session, a connectivity request message including information indicating that the session that needs to be always-on, or in other words, always-connected, has been requested.

Abstract: An embodiment of the present specification provides a method for acquiring an identifier of a visited public land mobile network (V-PLMN), in which a user equipment is roaming, by a proxy-call session control function (P-CSCF) of a home public land mobile network (H-PLMN). The method may comprise the steps of: receiving a register message from the user equipment; generating a first V-PLMN identifier on the basis of the register message; and transferring the first V-PLMN identifier to a home subscriber server (HSS), wherein whether the first V-PLMN identifier corresponds to an identifier of the V-PLMN which is serving the user equipment is verified by the HSS through comparison with a second V-PLMN identifier acquired in an initial attach procedure for an evolved packet core (EPC) of the user equipment.
