    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: An embodiment of the present invention relates to a method for performing a registration through a first network access and a second network access by user equipment (UE) in a wireless communication system, the method comprising the steps of: performing a registration through a first network access by UE; and performing a registration through a second network access by the UE, wherein when the first network access and the second network access belong to an identical public land mobile network (PLMN), the UE starts a registration through the second network access only after a registration procedure thereof through the first network access has been completed.

    Abstract: One disclosure of the present disclosure provides a method by which SMF performs communication. The method comprises the steps of: receiving, from a user equipment (UE), a protocol data unit (PDU) session establishment request message for a PDU session; transmitting, to the UE, a PDU session establishment acknowledgment message for the PDU session, wherein the PDU session is for an uncrewed aerial system (UAS) service; determining whether to maintain network resources for the UAS service, on the basis of the UAS service being unavailable; transmitting an N4 session modification request message that indicates a use report to a user plane function (UPF), on the basis of the determination to maintain the network resources for the UAS service; and receiving a usage report from the UPF, on the basis of the N4 modification request message.

    Abstract: One disclosure of the present specification provides a method by which a network control node performs communication. The method comprises the steps of: determining whether to request, from a network function (NF), control for a network slice on the basis of a session, which is managed by a network control node, being related to an interworking procedure and on the basis of the network slice being controlled by a provider policy set in the network control node, the network slice being related to the session; transmitting a control request message for the network slice to the NF, on the basis of the determination that the network control node requests control for the network slice; and receiving a response message from the NF, wherein the response message includes information about whether the session is available in the network slice.
