An Efficient Policy Retrieval and Wi-Fi Control for ANDSF System

摘要

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 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.
