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 3 G operators face massive challenges in managing the huge amount of mobile data traffic. Thus, mobile data offloading to non-3GPP access networks in 3G-access networks is necessary. In this paper, we propose a novel ANDSF-assisted Wi-Fi control method based on user's high-level motion states, such as walking, driving, and recognizing whether the user is stationary or not, to avoid unnecessary Wi-Fi scanning and connections. The proposed method is compared to a client-based Wi-Fi connection manager, which performs periodic Wi-Fi scanning. According to the performance results, the proposed mechanism shows significant performance improvement in terms of efficient Wi-Fi scanning and connections.
