Abstract: Provided in one disclosure of the present specification is a method by which a session management function (SMF) node manages a session. The method can comprise the steps of: transmitting, to an access and mobility management function (AMF) node, a registration request for notifying of state information of user equipment (UE) capable of accessing a local area data network (LADN) through any one of a first access network and a second access network; receiving, from the AMF node, changed state information when the state information of the UE is changed; and determining whether to release or deactivate a PDU session of the UE on the basis of the received information.

Abstract: A disclosure of the present specification provides a network access blocking method performed by a user equipment. The method may comprise the steps of: receiving application specific congestion control for data communication (ACDC) blocking information and access class barring (ACB) blocking information; determining the category of an application being executed according to a network access attempt by the application; performing an ACDC blocking check on the basis of the determined category and the received ACDC blocking information. Here, when the network access attempt by the application is not blocked as a result of the ACDC blocking check, an ACB blocking check on the basis of the ACB blocking information may be skipped.
