Abstract: Provided are a method of performing public land mobile network (PLMN) selection and a device supporting the method. According to one embodiment of the present invention, a method for performing PLMN selection in a wireless communication system includes: entering an RRC_INACTIVE state; transmitting, to a non-access stratum (NAS) layer of the UE, information on whether or not there is on-going data; receiving, from the NAS layer of the UE, a request of a PLMN searching when there is no on-going data; and performing the PLMN searching based on the request of the PLMN searching.

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 network may instruct to change the connection of a user equipment connected to the network in a first mode, to a second mode. The network may instruct re-establishment while instructing the user equipment to change the connection. In this case, the network and the user equipment release the connection of the first mode while maintaining an uplink resource allocated to the user equipment. After completing the connection release, the user equipment may transmit a connection request to the network using the uplink resource directly without any access process.

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.
