AB WLAN hot-spots are becoming widely spread. This, combined with the availability of new multi-mode terminals integrating heterogeneous technologies, opens new business opportunities for mobile operators. Scenarios in which 3G coverage is complemented by WLAN deployments are becoming available. Thus, true all-IP based networks are ready to offer a new varietyof services across heterogeneous access. However, to achieve this, some aspects still need to be analyzed. In particular, the effect of the terminal speed on the detection and selection process of the preferred access network is not yet well understood. Infact, efficiency of vertical handovers depends on the appropriate configuration of mobile devices. In this paper we present asimulation study of handover performance between 3G and WLAN access networks showing the impact of mobile users’ speed. The mobile devices are based on the IEEE 802.21 crosslayer architecture and use WLAN signal level thresholds as handover criteria. A novel algorithm to dynamically adjust terminals’ configuration is presented.
