Abstract: A method and apparatus for preventing loss of uplink data in wireless communication system is provided. A central unit (CU) of an integrated access and backhaul (IAB)-donor receives, from a wireless device, uplink data through a source IAB-node. The CU of the IAB-donor receives, from the source IAB-node, a message which informs that uplink packets among the uplink data are remained on the source IAB-node, wherein the message is related to handover procedures of the wireless device from the source IAB-node to a target IAB-node. The CU of the IAB-donor proceeds the handover procedures, after receiving the uplink packets.

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.
