Abstract: Provided are a method for adjusting timer T when disaster roaming occurs, and a device supporting same. When a disaster condition is applied to a home public land mobile network (HPLMN), a user equipment (UE) performs registration with a disaster roaming PLMN. When the registration with the disaster roaming PLMN is performed, a timer for periodically searching for the HPLMN does not operate, and the HPLMN is not searched while the timer does not operate. In addition, the UE re-operates the timer on the basis of the disaster condition no longer being applied to the HPLMN or the UE leaving a disaster area.

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: A disclosure of the present specification provides a method for a terminal to perform communication related to an IMS. The method may comprise the steps of: receiving, by an NAS layer of a terminal, a first request message from an IMS layer of the terminal, wherein the first request message includes information related to IMS signaling for a non-service attempt and information about a first access category among a plurality of access categories related to an IMS service, and the IMS signaling for the non-service attempt is signaling which does not request the IMS service; and transmitting, by the NAS layer of the terminal, a second request message including the information about the first access category to an RRC layer of the terminal.

Abstract: A method for selecting, by a user equipment (UE), a public land mobile network (PLMN) in a wireless communication system is disclosed. The method includes attempting a registration on a PLMN selected by a user in a manual network selection mode, if the registration on the PLMN selected by the user cannot be achieved, finding one or more PLMNs offering access to restricted local operator service (RLOS), selecting a specific PLMN of the found one or more PLMNs among PLMNs contained in a RLOS PLMN list configured to a universal subscriber identity module (USIM) of the UE, and initiating a registration for an access to RLOS on the specific PLMN, thereby using RLOS with high quality and high security.

Abstract: Disclosed in the present specification is a method by which a user equipment (UE) performs access control. The method comprises the steps of: allowing a non-access-stratum (NAS) layer of the UE to transfer information on an important service and a NAS signaling request to a radio resource control (RRC) layer, when the important service is required even if access to a cell is currently interrupted or a back-off timer is operated; and allowing the RRC layer to skip or override an inspection for access control on the basis of the information on the important service, wherein, the information on the important service can be set in advance.

Abstract: User equipment may send a channel allocation request (hereinafter referred to as a first channel allocation request) to a network for transmission of data. When the transmission of data has backed off, the user equipment may send a channel allocation request (hereinafter referred to as a second channel allocation request) again for the transmission of data. At this time, the second channel allocation request may be transmitted to the network together with a priority raise request if a remaining timeframe Tremain of an upper timeframe T is smaller than a certain guard time.
