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: One disclosure of the present specification provides a method by which a network node performs communication related to an MA PDU session. The method may comprise the steps of: receiving, from a UE, a SIP registration message including MA PDU session information; receiving, from another network node, a SIP message related to an IMS service for the MA PDU session; and transmitting, to a PCF node, information on whether the SIP message is related to a PS Data Off exempt service, on the basis of the reception of the MA PDU session information.

Abstract: Provided in one disclosure in the present specification is a multi-access (MA) protocol data unit (PDU) session method using user equipment (UE). The method can comprise a step of transmitting a first request message for a performance measurement function (PMF) binding request to a PMF layer of a user plane function (UPF) node on the basis of PMF address information about the UPF node included in measurement assistance information (MAI). The PMF binding request can be performed according to quality of service (QoS) flow. The method can comprise a step of receiving a PMF binding response message from the PMF layer of the UPF node. The PMF binding response message can include a reflective QoS indication (RQI).

Abstract: Provided in one disclosure of the present specification is a user equipment (UE) for establishing a Protocol Data Unit (PDU) session. The UE may include: a transmission and reception unit; and a processor for controlling the transmission and reception unit. The processor may perform: a step for assessing whether there is a possibility of the PDU session being handed over to a non-3rd Generation Partnership Project (non-3GPP) access; a step for determining the ID of the PDU session according to the assessment; and a step for transmitting a message including the determined ID of the PDU session.

Abstract: A first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.

Abstract: Systems and techniques for handling a protocol data unit (PDU) session by a wireless device implementing an access stratum (AS) layer and a non-access stratum (NAS) layer in a wireless communication system. An example technique includes determining, by the AS layer of the wireless device, whether a user plane for the PDU session is activated or released; transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is activated, first information indicating that the user plane for the PDU session is activated; and transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is released, second information indicating that the user plane for the PDU session is released.

Abstract: A method performed by a terminal operating in a wireless communication system. Based on that the terminal is located in a non-allowed area, and based on the terminal having a pending uplink signaling to inform a change in a Packet Switch (PS) data off status of the terminal, the terminal transmits a service request message to a network node. The service request message includes service type information that is related to the change in the PS data off status of the terminal. The terminal then receives, from the network node, a response message to the service request message.
