Abstract: A method and apparatus for handling QoE report in a secondary node in a wireless communication system is provided. An SN transmits, to a UE, a configuration for Quality of Experience (QoE) measurement. The QoE measurement is initiated by an Operations, Administration and Maintenance (OAM) and/or a master node (MN). An SN receives, from the UE, a QoE report based on the configuration. An SN determines whether to forward the QoE report to (i) a Trace Collection Entity (TCE) and/or a Measurement Collection Entity (MCE) and/or (ii) the MN, based on which entity among the OAM and/or the MN initiates the QoE measurement. An SN forwards the QoE report based on the determination.

Abstract: A method and apparatus for stopping multicast and broadcast service in a wireless communication system is provided. A CU-UP of a RAN node receives, from a CU-CP of the RAN node, a first message to initiate a MLD) and/or IGMP Leave procedure. A CU-UP of a RAN node performs the MLD and/or IGMP Leave procedure for the MB service indicated by the identity for the MB service along with an MB-UPF based on the Transmission Stop Indication. A CU-UP of a RAN node transmits, to the CU-CP of the RAN node, a second message informing that the MLD and/or IGMP Leave procedure is completed.

Abstract: A method and apparatus for support of Mobile-Terminated Small Data Transmission (MT-SDT) considering Central Unit (CU)-Distributed Unit (DU) split is provided. A receiving gNB receives a Radio Access Network (RAN) paging message from a last serving gNB. The RAN paging message includes an MT-SDT indication informing that a MT-SDT is supported. The receiving gNB transmits a Retrieve UE Context Request message to the last serving gNB based on an Inactive Radio Network Temporary Identity (I-RNTI). The Retrieve UE Context Request message includes information about a Downlink (DL) Transport Network Layer (TNL) address associated with the MT-SDT. The receiving gNB receives DL data associated with the MT-SDT from the last serving gNB based on the DL TNL address, and transmits the DL data to the UE.

Abstract: Provided is a method and device for an N14 interface support indicator for service continuity. A next generation radio access network (NG-RAN) node of a first network receives an initial UE context configuration request message from an access and mobility management function (AMF) of the first network. The initial UE context configuration request message includes (i) a registration acceptance message that is a response to a registration request message, and (ii) information on at least one second network supported by the first network, and the registration acceptance message includes information on whether an N14 interface between the AMF of the first network and an AMF of the at least one second network is supported. The NG-RAN node of the first network initiates handover to one network among the at least one second network, based on the information on the at least one second network.

Abstract: A method and apparatus for supporting a DAPS handover procedure in a wireless communication system is provided. A target BS receives, from a source BS, a first message for a dual active protocol stack (DAPS) handover of a wireless device. A target BS transmits, to the source BS, a second message to inform that the DAPS handover is accepted. A target BS receives, from the wireless device, a third message including an information that the wireless device does not perform the DAPS handover. A target BS transmits, to the source BS, a fourth message including the information received from the wireless device.

Abstract: A method and apparatus for controlling mobile early data transmission (EDT) procedure in a wireless communication system is provided. A first core network node, in a wireless communication, receives, from a second core network node, a message for a downlink Data including a size of the downlink data. The first core network node determines whether to initiate an early data transmission (EDT) procedure for the downlink data based on the size of the downlink data. The first core network node transmits, to a radio access network (RAN) node, a paging message including information related to the EDT procedure for the downlink data based on the decision to initiate the EDT procedure for a wireless device.
