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 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.

Abstract: Data-off can be activated in a user equipment. If a packet data network gateway receives a downlink packet to be transmitted to the user equipment in which data-off has been activated, the packet data network gateway transmits to the user equipment, or blocks, the downlink packet for the user equipment by using a filter associated with a data-off exception service.
