Abstract: A method and apparatus for establishing and modifying a traffic path on basis of a service data flow in a mobile communication system is proposed. The method includes steps of receiving an SM policy association establishment request message or an SM policy association modification request message on the basis of PDU session establishment, obtaining policy-related information from a UDR on the basis of an SM policy association establishment request or an SM policy association modification request, and performing a policy decision on the basis of whether a previously stored PCC rule related to the PDU session establishment exists in the policy-related information, wherein the policy decision may include traffic routing for each service data flow (SDF) and include a step of transmitting an SM policy association establishment response message or an SM policy association modification response message, which includes policy decision information, to a SMF.

Abstract: According to an exemplary embodiment of the present invention, a method for managing a resource using an apparatus for managing a resource is provided. The apparatus for managing a resource generates a first instance for a first community using a first ontology class about communities including at least one resource as a member according to a goal. The apparatus for managing a resource generates a second instance for a first resource using a second ontology class about resources. Further, the apparatus for managing a resource estimates a relation between the first instance and the second instance.
