Abstract: One disclosure of the present specification provides a method by which a Session Management Function (SMF) provides a multicast service. The SMF performs the steps of: receiving a first message from a relay user equipment (UE), wherein on the basis of the relay UE receiving a join request of a first remote UE for a multicast group from the first remote UE, the first message includes (i) the join request of the first remote UE and (ii) information about the first remote UE, and on the basis of the relay UE wanting to join the multicast group by itself, the first message includes a join request of the relay UE; checking whether the join request included in the first message is a first join request for the multicast group from among the relay UE and one or more remote UEs receiving a network connection service from the relay UE; and on the basis of the join request included in the first message being the first join request for the multicast group from among the relay UE and the one or more remote UEs receiving a network connection service from the relay UE, transmitting a second message to a base station.

Abstract: A network registration method for traffic steering and a device supporting the same is provided. An Access and mobility Management Function (AMF) receives a registration request message from a UE over a second non-3rd Generation Partnership Project (non-3GPP) access. The registration request message includes information related to access witching from a first non-3GPP access to the second non-3GPP access. Based on the registration request message, the AMF i) performs a normal registration procedure, and ii) delays a Unified Data Management (UDM) registration procedure. In addition, upon receiving, from a Session Management Function (SMF), information informing that the access switching from the first non-3GPP access to the second non-3GPP access is completed for the UE, the AMF performs an Access Network (AN) release procedure over the first non-3GPP access, performs the delayed UDM registration procedure.

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).
