    • A vertical handover method in an overlay network is provided to configure a handover map by considering network loads of each network as well as a location of a terminal, and to determine handover based on the handover map, thereby minimizing packet loss by distributing traffic, consequently system capacities can be maximized. When a terminal is located in a measurement area of a handover map, the terminal searches a reachable wireless network by activating all of connectable network interfaces(S401-S411). The terminal determines a target network to which handover is to be performed among the reachable networks(S413-S419). It is decided whether to perform the handover to the determined target network(S421). If so, the terminal performs the handover to the target network(S423).
    • 提供覆盖网络中的垂直切换方法,以通过考虑每个网络的网络负载以及终端的位置来配置切换地图,并且基于切换图确定切换,从而通过分配业务来最小化分组丢失,因此 系统容量可以最大化。 当终端位于切换地图的测量区域中时,终端通过激活所有可连接的网络接口来搜索可到达的无线网络(S401-S411)。 终端确定可到达网络之间进行切换的目标网络(S413-S419)。 决定是否执行到确定的目标网络的切换(S421)。 如果是,终端执行到目标网络的切换(S423)。
