The method may comprise a step for transmitting a first request message to a network node through a base station. The base station may be a base station of a second PLMN that broadcasts system information including information about the first PLMN. The method may comprise a step for receiving, from the network node, a first acceptance message for the first request message. The first acceptance message may include information indicating that there is a service failure in the first PLMN.

Abstract: Provided in one embodiment of the present specification is a method for user equipment (UE) for an Internet protocol multimedia subsystem (IMS) voice session. The method can comprise the steps of: establishing an EMS voice session by using a non 3GPP interworking function (N3IWF) or an enhanced packet data gateway (ePDG) through non-3rd generation partnership project (3GPP) access; determining that voice is not supported on a current NG-RAN on the basis of that the UE must moves the IMS voice session to a 3GPP access; and handing over a protocol data unit (PDU) session for the IMS voice session of the non-3GPP access to an evolved packet core (EPC) of the 3GPP access on the basis of the determination.

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.
