Abstract: In a wireless communication system of the present disclosure, when activation of a protocol data unit (PDU) session of a user equipment (UE) is needed, the UE performs an access control check to determine whether an access attempt for the PDU session is allowed. If the access attempt is allowed, the UE transmits a service request for the PDU session. The access control check for the PDU session is performed even if the UE is in a connected state.

Abstract: A method of receiving, by a user equipment (UE), a paging signal in a wireless communication system is disclosed. More specifically, the UE performs a registration to a plurality of networks, obtains a plurality of monitoring time points that has to check whether a paging message is received from each of the plurality of networks, when at least some of the plurality of monitoring time points overlap, transmits, to a first network, a change request of a first monitoring time point that has to check whether a first paging message is received from the first network of the plurality of networks, receives, from the first network, configuration information related to the request, and updates the first monitoring time point based on the configuration information.

Abstract: Disclosed are a method for performing registration with a network in a wireless communication system and a device therefor. Specifically, a method for performing registration with a core network by a user equipment (UE) in a wireless communication system may comprise the steps of: transmitting a registration request message to a first core network in a first cell; receiving a registration rejection message from the first core network in the first cell; discovering a second core network which is of a different type from the first core network and is supported in the first cell; when the second core network supported in the first cell is discovered, determining whether the UE supports the second core network; and when the UE supports the second core network, performing a registration procedure with the second network in the first cell.

Abstract: A core network to which a cell of a base station can be connected may not be specified to be one. For example, a cell may be connected to an EPC, may be connected to a next-generation core network, or may be connected to both an EPC and a next-generation core network. The base station may transmit core network information relating to a core network to which the cell is connected, on the cell. A user equipment may determine whether to camp on the cell on the basis of the core network information.

Abstract: Disclosed is a method for transmitting data traffic, the method comprising: receiving control information for indicating that the transmission of data traffic of a specific application is suppressed; determining whether uplink data traffic is for the specific application suppressed by the control information, if the uplink data traffic is received from an application layer, deleting the uplink data traffic if it is indicated that the uplink data traffic is to be suppressed; and transmitting the uplink data traffic to a network entity if it is not indicated that the uplink data traffic is to be suppressed.

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: One disclosure of the present specification provides a method for a terminal creating a session, the terminal supporting next-generation mobile communication. The method may comprise the steps of: determining that a session must be newly created if the creation of a session is not included in a process of attaching to a core network of a next-generation mobile communication; on the basis of service type information, determining that the session being newly created needs to be always-on, or in other words, always-connected; and transmitting, to a control plane (CP) function node for managing the session, a connectivity request message including information indicating that the session that needs to be always-on, or in other words, always-connected, has been requested.

Abstract: The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time advance groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS).
