Abstract	Currently, researchers introduce the dwell timer to reduce the ping-pang effect when they study the handover between heterogeneous networks. Simulations show that this kind of algorithms have a good effect in the case of that the terminal is in the coverage area of multiple access networks and does not leave away from the interactive network. However, if the terminal leaves away from the original network and needs to re-select a new network, the latency of those algorithms may lead to drop calls. Besides, when the terminal moves through the edge of the networks in a high speed, if the terminal select the WLAN access point it may result in frequent handovers because of its relative small coverage area. In this paper we propose a strategy based on movement-aware addressing the above problems. Our simulation results show that the strategy can make the terminal handover to the optimal network according to the users' preference timely and effectively and reduce the unnecessary handovers.
