Abstract: One disclosure of the present specification provides a method for using packet switching (PS) data off function in user equipment (UE). The method can comprise the steps of: determining whether a session management (SM) delay time timer or a mobility management (MM) delay time timer is being operated, in a state in which the transmission of a non-access stratum (NAS) request message for an SM is required according to a request for the activation or the inactivation of the PS data off function; and, according to the result of the determination, allowing an NAS layer of the UE to include activation or inactivation state information of the PS data off function in the NAS request message for an SM and transmit the same.

Abstract: One disclosure of the present specification provides a method for supporting redundant protocol data unit (PDU) sessions. The method may be performed by a unified data management (UDM) node and comprise: receiving, from a first session management function (SMF) node, a first message including a first redundancy sequence number (RSN) which is allocated by the first SMF node for managing a first PDU session and an identifier of the first PDU session; transmitting, to a second SMF node for managing a second PDU session, a second message including the first RSN and a PDU session pair ID, which is identical to the identifier of the first PDU session; and receiving, from the second SMF node, a third message including a second RSN which is allocated by the second SMF node and an identifier of the second PDU session. The second PDU session may be duplication of the first PDU session.

Abstract: Provided are a method by which a base station performs vehicle to everything (V2X) communication in a wireless communication system, and an apparatus for supporting the same. The method can comprise the steps of: receiving a V2X bearer indication indicating a V2X bearer, wherein the V2X bearer is a bearer used for a V2X service; determining that the base station supports only a PC5-based V2X service between the PC5-based V2X service or a Uu-based V2X service; postponing a resource allocation for the V2X bearer; and transmitting, to a mobility management entity (MME), information indicating that the resource allocation for the V2X bearer is postponed.

Abstract: A disclosure of the present specification provides a method for blocking network access. The method may comprise the steps of: receiving application specific congestion control for data communication (ACDC) blocking information; driving a blocking timer when it is determined by an ACDC blocking check that a network access attempt by a first application being executed is blocked; determining the category of a second application being executed according to a network access attempt by the second application; performing an ACDC blocking check on the basis of the determined category of the second application and the received ACDC blocking information when the determined category of the second application has a higher priority than the category of the first application; and stopping the blocking timer when the network access attempt by the second application should be permitted according to the ACDC blocking check.

Abstract: A method and apparatus for sidelink connection suspension or release based on different target qualities of different services in a wireless communication system is provided. A first wireless device determines a first target cell quality for a first service related to a first bearer and a second target cell quality for a second service related to a second bearer. The first wireless device suspends at least one of the first bearer and/or the second bearer based on that a result of the measurement on a sidelink connection does not meet at least one of the first target cell quality and/or the second target cell quality. The first wireless device releases the sidelink connection if there is no more service using the sidelink connection.

Abstract: A method for a user equipment (UE) connecting to a network includes: if second connection is to be executed by means of a second access, determining whether or not first connection has been previously executed by means of a first access; and, if the first connection by means of the first access has been executed and the second connection by means of the second access is determined to be an addition, transmitting a connection request message comprising identification information of a control plane (CP) function node. The identification information of the control plane (CP) function node could have been obtained during the first connection by means of the first access. Both the first connection by means of the first access and the second connection by means of the second access can be managed by means of the control plane (CP) function node.
