Abstract: A method performed by a terminal operating in a wireless communication system. Based on that the terminal is located in a non-allowed area, and based on the terminal having a pending uplink signaling to inform a change in a Packet Switch (PS) data off status of the terminal, the terminal transmits a service request message to a network node. The service request message includes service type information that is related to the change in the PS data off status of the terminal. The terminal then receives, from the network node, a response message to the service request message.

Abstract: Disclosed are a method for performing V2X communication in a wireless communication system and an apparatus therefor. Specifically, a method for supporting, by a base station, a user equipment (UE) to perform vehicle-to-everything (V2X) communication with a vehicle through a PC5 interface in a wireless communication system may include: receiving a sidelink UE information message for requesting resource allocation for the V2X communication through the PC5 interface from a UE in a limited service state; checking whether the UE has a capability to use the V2X communication with an emergency packet data network (PDN) connection or whether the UE is authorized to perform the V2X communication; and allocating a resource for the V2X communication when the UE has the capability to use the V2X communication with the emergency (PDN) connection or the UE is authorized to perform the V2X communication.

Abstract: A method for performing vehicle-to-everything (V2X) communication in a wireless communication system and a device for same are disclosed. Particularly, a method for a user equipment (UE) performing V2X communication by means of a PC5 interface in a wireless communication system comprises the steps of: receiving from an upper layer a request for transmitting a V2X message; requesting radio resources, for V2X communication by means of a PC5 interface, to a base station or selecting radio resources for V2X communication by means of the PC5 interface; and performing transmission of V2X communication by means of the PC5 interface, wherein, if a UE has emergency packet data network (PDN) connection, an indication, indicating that transmission by means of the emergency PDN connection is a higher priority than the V2X communication by means of the PC5 interface, can be transmitted from the upper layer.

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.
