移动性需求 全球移动设备明年增长54%,2011年将达 到8000万台: IDC, 2007.6.2 对移动性支持越来越重要移动计算、 移动商务、WAP、 GPRS、3G、 WiMax

全IP化时代的到来接入与承载：Ethernet, WiMax, DSL, ASON 业务系统：H.323, SIP, IMS, AMS(H.325)

未来Internet上99%将会是移动业务Copyright © 2007, RITT, MII.

IP地址的双重作用Locator Identifier

仅有漫游是不够的避免IP地址为基础的应用中断 服务器的移动需求 网络注册系统的IP地址范围限制 安全性机制要求如果移动节点发起通信，不介意改变位置重启应用 漫游功能已经足够Copyright © 2007, RITT, MII.
