Abstract: Provided are a method and apparatus for: access to a stand-alone non-public network (SNPN) by using credential owned by an entity separated from the SNPN; and support for an F1 interface therefor. User Equipment (UE) operating in a wireless communication system receives system information from the stand-alone non-public network (SNPN). The system information includes information about whether or not the SNPN supports underconfigured UE. The UE transmits a first registration request message to the SNPN, on the basis of the information about whether or not to support the underconfigured UE, and receives, from the SNPN, a registration reject message as a response to same. The registration reject message includes information about home SPs supported by the SNPN. The UE performs registration by selecting at least one home SP from which the UE desires to receive a service from among the home SPs supported by the SNPN.

Abstract: A method and apparatus for support of service continuity for handover between stand-alone non-public network (SNPN) and public land mobile network (PLMN) is provided. A session management function (SMF) of a first network transmits, to a user plane function (UPF) of the first network, a duplication request for the UPF of the first network to duplicate downlink (DL) data and send the duplicated DL data to both a next generation radio access network (NG-RAN) of the first network and a non-3GPP interworking function (N3IWF) of the first network. The SMF of the first network further transmits, to the N3IWF of the first network, a data buffering request for the N3IWF of the first network to buffer the duplicated DL data.

Abstract: A method and apparatus for handling security information between a wireless device and a network for a fast RRC release procedure in a wireless communication system will be provided. A core network node in a wireless communication system receives, from a radio access network (RAN) node, a UE context resume request message including a fast Radio Resource Control (RRC) release indication. The fast RRC release indication informs that the RAN node transmits an RRC release message to a wireless device before the core network node receives the UE context resume request message. A core network node determines to stop computation of new security information for the wireless device based on the fast RRC release indication. A core network node transmits a UE context resume response message to the RAN node.

Abstract: A method and apparatus for supporting UP security for MO-EDT in CU-DU split in a wireless communication system is provided. A central unit (CU) receives, from a distributed unit (DU), a first message including a PDCP Data PDU, wherein the PDCP Data PDU is configured by a wireless device. A CU calculates a HASHDATA from the PDCP Data PDU. A CU verifies a Short MAC-I of the wireless device based on the HASHDATA. A CU transmits, to the DU, a second message to setup a UE context for the wireless device in the DU based on the verification.

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: A new cell specification procedure can be defined, in order to support more efficiently a network slice function in a new radio (NR) access technology as being a part of a 5G communication system. From a perspective of a radio access network (RAN)-core network (CN) interface, a RAN node can transmit, to a CN node, a first indicator related to the slice support of the RAN node, and receive, from the CN node, a second indicator related to the slice support of the CN node.
