Abstract: A method for offloading traffic in a wireless communication system, receiving, by a user equipment (UE), a deactivate bearer request indicating reactivation is required for a packet data network (PDN) connection, wherein the deactivate bearer request is triggered by a Mobility Management Entity (MME) which has obtained subscription data for the UE from a Home Subscriber Server (HSS) and has received local gateway (L-GW) information indicating a transport layer address of a L-GW being capable of offloading the traffic, wherein the subscription data for the UE is defined based on an Access Point Name (APN), wherein the subscription data for the UE includes a first information element indicating whether a corresponding traffic associated with the APN is allowed for Selected IP Traffic Offload (SIPTO) and a second information element indicating whether the corresponding traffic associated with the APN is allowed for Selected IP Traffic Offload via Local Network (SIPTO@LN).
