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.

Abstract: Provided in one disclosure of the present specification is a method selecting a network and routing traffic by a user equipment (UE). The method may comprise a step of receiving, from a base station, radio access network (RAN) support information, wherein the RAN support information may include RAN support parameters and a timer value. The method comprises the steps of: receiving, from an upper layer, an evaluation request; evaluating the RAN support parameters according to the request from the upper layer; delivering, to the upper layer, an indication which indicates a detour to wireless local area network (WLAN) access and a detour to 3GPP access according to the result of the evaluation, and/or an indication which indicates maintaining current access; and performing feedback to the step of evaluating when the timer expires.
