Abstract: A method, performed by an access and mobility management function (AMF), of providing information for a vehicle-to-everything (V2X) service is provided. The method includes receiving, from a user equipment (UE), a registration request message including information indicating that the UE is a V2X terminal, selecting, based on the registration request message, a policy control function (PCF) supporting the V2X service, receiving V2X policy information from the selected PCF, and providing the V2X policy information to a base station.

Abstract: Provided in the present disclosure are a method and a device for providing a service to a user device by using a network slice in a communication system. A method according to one embodiment of the present disclosure can comprise the steps of: receiving, from a second network function device, management function configuration information about a first core network slice, including the quota of a first core network slice; reporting status information about the first core network slice to a third network function device on the basis of the management function configuration information; receiving, from the third network function device, parameters for controlling the status of the first core network slice; and controlling access of a terminal that is to use the first core network slice, on the basis of the status information about the first core network slice and the parameters for control.
