摘要

在4G全IP无线网络环境中

提供无缝隙的移动性支持是严峻的挑战之一.移动性管理协议可以在协议栈的不同层(如链路层、网络层、传输层及应用层)进行实现

无论是在哪一层实现

都有其优缺点.从结构上看

网络层是最适当的层

但它需要修改协议栈;而应用层上的移动性管理协议由于对低层特性是透明的

似乎是一个很好的选择

但它会引入较大的时延.因此

一个真正开放的、适应性强的、高效的移动管理方案是下一代无线系统亟待解决的问题.

Abstract

Providing seamless mobility support is one of the most challenging problems towards the system integration of fourth generation (4G) all-IP wireless networks.Mobility management protocols can be operated in different layer (such as link layer

network layer

transport layer and application layer).Each of them comes with its own advantages and disadvantages according to the characteristics of its layer of operation.Architecturally

the network layer is the right layer

but the protocol stack needs to be modified.Because of the transparency to the lower layer characteristics

application-layer mobility management protocol seems a good choice

but it introduces larger latency.Therefore

a real open

accommodative but still efficient mobility management solution is called for by the next-generation wireless system.
