Abstract: The present description discloses a method for performing network selection and traffic routing by a mobility management entity (MME). The method comprises the steps of: if a request for a public data network (PDN) connection is received from a user equipment (UE), an MME deciding whether or not the PDN connection is to be offloaded to a wireless local area network (WLAN) on the basis of an indication for WLAN offloadability obtained from a home subscriber server (HSS); the MME transmitting to the UE a message comprising information about a network-based IP flow mobility (NBIFOM) function and the decision result with respect to the PDN connection; and the MME transmitting the decision result with respect to the PDN connection to a PDN gateway (P-GW) and/or a policy and charging rules function (PCRF), wherein the decision result with respect to the PDN connection and the information about the NBIFOM function can be used for triggering any one of the UE, P-GW and PCRF such that the NBIFOM function is suspended or resumed.

Abstract: A method is provided for performing network selection and traffic routing. A user equipment (UE) receives an Access Network Discovery and Selection Function (ANDSF) rule including an Inter-System Routing Policy (ISRP) rule or an Inter-Access Point Name (Inter-APN) Routing Policy (IARP) rule. The UE receives, from a base station, radio access network (RAN) assistance information. The RAN assistance information received from the base station is used to evaluate the ISRP rule or the IARP rule of the ANDSF rule. The UE evaluates whether the ISRP rule or the IARP rule of the ANDSF rule is valid or not by using the RAN assistance information. The UE selects one of the RAN assistance information and the ANDSF rule including the ISRP rule or the IARP rule.

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.
