摘　　要：随着各种异构无线网络的相继出现,多种无线网络融合基础的垂直切换技术受到了学术界和工业界的广泛关注。因此,下一代无线网络(Next Generation Wireless Networks,NGWN)必须支持垂直切换技术以保证用户从一个网络切换到另一个网络或从一种传输媒体切换到另一种传输媒体时仍然保持已有通信的连续性。本文对目前垂直切换技术的基本思想及存在难点进行简要分析,同时引入一种使用多种判决因子的垂直切换判决策略,并对其核心思想及切换过程进行分析。Along with each kind of heterogeneous wireless network appearance one after another,many kinds of wireless network convergence foundation＇s vertical handoff technology has received widespread attention of the academic and the industrial world.Therefore,the next generation wireless network（NGWN） must support the vertical handoff technology to ensure that users can switch from a network to another or from one kind of transmission medium to another when maintained the continuity of the exist correspondence.This paper carries on the summary analysis of the present vertical handoff technology basic philosophy and the existence difficulty,simultaneously introduces a vertical handoff decision strategy using many kinds of decision factors,and elaborates its core thought and the handoff process.
