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: A disclosure in the present specification provides a method for user equipment initiating a service request procedure. The method includes a step of the UE receiving a paging message. The UE may be registered to both of a 3rd generation partnership project (3GPP) access and a non-3GPP access within the same PLMN. The paging message may include access type information that is used so as to indicate the non-3GPP access. The method may include a step of initiating a UE triggered service request procedure. The UE triggered service request procedure may be initiated by transmitting a service request message including a list of permitted protocol data unit (PDU) sessions. The service request message may include an empty list of the permitted PDU sessions if there is no PDU sessions that can be reactivated in the 3GPP access.

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.
