Abstract: One disclosure of the present specification provides a method for establishing communication by a session management function (SMF). The method comprises the steps of: transmitting to a base station a request message requesting resource allocation between a first protocol data unit (PDU) session and a second PDU session, wherein the first PDU session and the second PDU session are established by user equipment (UE) on the basis of the same PDU session pair ID; receiving a response message from the base station, wherein the response message comprises indication information indicating whether or not a disjoint UP path is allocated to the first PDU session and the second PDU session, respectively; and transmitting the indication information to the UE.

Abstract: A disclosure of the present specification provides a method for performing, by a first RAN node, communication related to a network slice. The method may comprise the steps of: receiving, from an AMF, a PDU session resource establishment request message including information regarding a second PDU session; on the basis of the first RAN node not supporting a second network slice, determining to move UE to a second RAN node that supports the second network slice; and on the basis of being determined to move the UE to the second node, transmitting a PDU session resource establishment response message to the AMF.

Abstract: A method and apparatus for support of service continuity between stand-alone non-public network (SNPN) and public land mobile network (PLMN) is provided. A wireless device transmits, to an access and mobility management function (AMF) of a source network, a protocol data unit (PDU) session establishment request to establish a PDU session with the source network via a non-3GPP interworking function (N3IWF) of the source network. The PDU session establishment request includes information informing that data delivery is not available via the PDU session. The wireless device determines to move from the source network to a target network, and transmits, to a user plane function (UPF) of the source network, mobility information informing that the wireless device moves from the source network to the target network.
