This paper presents a strategic solution to mobile data offloading between 3GPP and non-3GPP access networks. As mobile data traffic is increasing rapidly, many 3G operators face massive challenges in managing the huge amount of mobile data traffic. Thus, mobile data offloading to non-3GPP access network in a 3G-access network is inevitable. In this paper, we propose a distributed Access Network Discovery and Selection Function (ANDSF) information provisioning architecture for mobile data offloading through the evolved packet system (EPS). We first discuss the ANDSF that has been specified in 3GPP to argue the problems in terms of scalability and energy efficiency. To address these issues on the ANDSF, we analyze the functions and roles of the EPS to provide ANDSF information instead of the existing ANDSF server on the EPS. Based on an analysis of the EPS, we show an effective method of mobile data offloading by distributing ANDSF information over the EPS.
