ABC : A New Approach to Seamless Mobility between Cellular Networks and WLAN

With the advent of new innovative mobility protocols, it is hard to realize seamless mobility. There are several reasons for this problem. First, service providers have to deploy in the entire networks and this demands a lot of financial investment. Second, even with those innovations, new mobility protocols are likely to be ignored by customers if it costs a lot of money for subscribers. Third, it is likely that most mobility protocols does not support both high bandwidth and large range. Although the widespread deployment of cellular networks guarantees mobility in large range, it cannot completely support multimedia data. Similarly, although the explosive growth of WLAN provides the convenience of wireless with high bandwidth, it lacks large range support. Thus, in this paper, we propose a new approach, ABC, for seamless mobility such that our approach provides both high bandwidth and large range.
