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: Provided are a method and device for efficient public land mobile network (PLMN) selection upon authentication failure for each network slice in a roaming network. A user equipment (UE) receives a registration rejection message from an access and mobility management function (AMF) of a first PLMN. The registration rejection message includes rejected network slice selection assistance information (NSSAI) including first single NSSAI (S-NSSAI) and cause value #62 for the rejected NSSAI. The UE: generates second requested NSSAI including second S-NSSAI on the basis that i) the UE does not have allowed NSSAI and configured NSSAI, and ii) default configured NSSAI includes the second S-NSSAI that is not included in the rejected NSSAI and corresponds to a network slice of which the UE requests registration; and transmits a second registration request message including the second requested NSSAI to the AMF of the first PLMN.

Abstract: One aspect in the present specification is a method for a terminal to connect to a network in a wireless communication system, wherein the method can include: searching a network usable by the terminal; receiving, from the searched network, information about access groups supported by the searched network; determining, on the basis of the access group information, whether an identifier of the access group included in an allowed access group list preset in the terminal is included in the access group information; receiving, from the searched network, control information related to an access group for selecting the searched network; transmitting a registration request message to the searched network on the basis of the control information; and receiving a response message from the searched network as a response to the registration request message.

Abstract: Provided is a method for carrying out access control in a radio resource control (RRC) connected mode according to a disclosure of the present specification. The method may comprise the steps of: a non-access stratum (NAS)layer of a terminal determining an access category if outgoing (MO) data to be transmitted or outgoing (MO) signaling occurs; the NAS layer transmitting the NAS signaling message and access category to an access stratum (AS) layer if no disconnection is determined as a result of carrying out a termination test for access control on the basis of the access category; and the AS stratum of the terminal transmitting, to a base station, an RRC message comprising at least one from among the access category, call type, and reason for setup.

Abstract: A user equipment (UE) may receive or transmit a protocol data unit (PDU). The PDU includes a service data unit (SDU) type field. The SDU type field may be set to a value indicating a vehicle-to-everything (V2X) type. When the SDU type field is set to a value indicating a V2X type, the PDU may include an additional field indicating an application or protocol type for data of an SDU in the PDU.

Abstract: A method for restarting a prohibit timer in a wireless communication system, the method performed by a user equipment (UE) includes starting the prohibit timer related to a transmission of power preference information; receiving, from a network, a handover message including a timer value; performing a handover procedure based on the received handover message; restarting the prohibit timer based on applying the received timer value included in the handover message; and stopping the prohibit timer based on whether the UE initiates radio resource control (RRC) re-establishment procedure while the prohibit timer is running. Further, upon initiating the RRC re-establishment procedure, the UE disables the transmission of the power preference information and stops the prohibit timer.

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.
