Abstract: One disclosure in the present specification provides a session management method performed by a session management function (SMF) node. The session management method may comprise: a step of transmitting, to a user plane function (UPF) node, a request message for discarding traffic buffering, when a notification of the detection of particular traffic associated with a wireless device has been received, and if additional authentication is required for the particular traffic; and a step of transmitting a message for triggering the wireless device to establish a new packet data unit (PDU) session, to an access and mobility management function (AMF) node.

Abstract: One disclosure of the present specification provides a method for supporting service continuity after a terminal performs a handover. The method may comprise: a step of transmitting, when re-assigned from a source user plane (UP) functional node to a target UP functional node in accordance with performing a handover to a target base station, a PDU session creation request message to create a new PDU session with the target UP functional node; a step of receiving a PDU session creation response message including a newly allocated second IP address; a step of transmitting a tunneling request message including information on the newly allocated second IP address and information on a service flow requiring service continuity; and a step of encapsulating a packet, which has been generated with an existing first IP address by an upper layer of the terminal, with a new second IP address by a lower layer of the terminal and transmitting the encapsulated packet to the tunneling entity.

Abstract: One disclosure of the present specification provides a method for a control plane (CP) function entity creating a session, the CP function entity being in charge of managing a session in a next-generation mobile communication network. The method may comprise the steps of: receiving a connectivity request message from a terminal if the creation of a session is not included in a process by which the terminal attaches to a core network of the next-generation mobile communication; on the basis of information on the type of service to be provided to the terminal, deciding to create, for the terminal, a session that needs to be always-on, or in other words, always-connected; and transmitting, to the terminal, a connectivity completion message including information indicating the session that needs to be always-on, or in other words, always-connected.

Abstract: A method for adjusting a timer value for a device includes determining, by a home subscribing server (HSS), a timer value for a routing area update (RAU) or a tracking area update (TAU) based on a maximum time period, wherein the timer value for the RAU or the TAU is determined to be a smaller value than the maximum time period, wherein the maximum time period is related to a loss of a connectivity indicating the device is no longer possible to be signaled, and delivering, by the HSS, information regarding the determined timer value for the RAU or the TAU to a Mobility Management Entity (MME)/Serving General Packet Radio Service (GPRS) Supporting Node (SGSN).

Abstract: An embodiment of the present description provides a method for rearranging a gateway by a node, which is in charge of a control plane, for a user equipment (UE) in a mobile communication network. The method can comprise the steps of: if a UE performs a handover and both the UE and an opponent device communicating with the UE are capable of supporting rearrangement of a gateway, determining an appropriate gateway for the UE to be rearranged; and transmitting a rearrangement indication to the UE on the basis of the determination.

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.
