    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 method of operating a first user equipment (UE) in a wireless communication system includes receiving information related to a sidelink bandwidth part (BWP) by the first UE, establishing a plurality of unicast links by the first UE, transmitting a sidelink signal in the sidelink BWP on a first unicast link among the plurality of unicast link, and releasing a second unicast link for which radio link failure (RLF) has been declared among the plurality of unicast links, based on the RLF and a PC5 link identifier (ID) by the first UE. The PC5 link ID is used to identify the second unicast link for which the RLF has been declared among the plurality of unicast links.

    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.
