Abstract: A method for processing a security policy of a device may include a step for receiving, from another device, a first message including first information about a security policy of the other device. The first message may include a direct communication request message or a link modification request message. The method may further include the steps of: determining whether to accept or reject the first message on the basis of both the first information about the security policy of the other device and second information about the security policy of the device; and sending a second message on the basis of the determination.

Abstract: Disclosed as a method of controlling access to a network in a wireless communication system and an apparatus therefor. Specifically, a method of performing access to a network by a user equipment (UE) in a wireless communication system may include receiving first information on whether a specific access identity is valid in a specific public land mobile network (PLMN) from the network, when the UE selects a PLMN and attempts access, determining whether the specific access identity is valid in the PLMN selected by the UE based on the first information, selecting an access identity based on the determination, and performing an access control procedure based on the selected access identity.

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: In a wireless communication system, a base station may transmit a paging message by selecting at least one path among a first transmission path for directly transmitting the paging message to a remote terminal on the basis of data type information of downlink data and a second transmission path for transmitting the paging message to the remote terminal through a relay terminal which relays data transmission and reception between the remote terminal and the base station.

Abstract: One disclosure of the present specification provides a method for a control plane (CP) function entity creating a session, the CP function entity being in charge of managing a session in a next-generation mobile communication network. The method may comprise the steps of: receiving a connectivity request message from a terminal if the creation of a session is not included in a process by which the terminal attaches to a core network of the next-generation mobile communication; on the basis of information on the type of service to be provided to the terminal, deciding to create, for the terminal, a session that needs to be always-on, or in other words, always-connected; and transmitting, to the terminal, a connectivity completion message including information indicating the session that needs to be always-on, or in other words, always-connected.

Abstract: A network node of the present invention transmits downlink data for user equipment using a paging message. The user equipment can transmit to the network node a radio resource control (RRC) connection request message including acknowledgement information that indicates acknowledgement of the downlink data if the paging message contains the downlink data for the user equipment. The network node can transmit to the user equipment an RRC connection refusal message including information that indicates confirmation with respect to the acknowledgement information if the paging message contains the downlink data for the user equipment and the RRC connection request message contains the acknowledgement information.
