下一代网络通用移动性管理技术初探

Generalized mobility management for next generation network

针对下一代网络(NGN)的通用移动性要求,阐述了符合NGN全IP网络传送这一特点的两类移动性解决方案--基于网络层解决方案(移动IP)和基于应用层解决方案(移动SIP),比较了它们在支持终端移动性、个人移动性和业务移动性支持上的优缺点,进而分析两者结合方案,提出将网络层移动性管理进行联合优化设计,是研究NGN通用移动性管理技术的一种努力方向。

This paper discussed the generalized mobility requirements of next generation networks (NGN) and reviewed two IP based mobility solutions: mobile IP (MIP) and mobile session initiation protocol (MSIP). We compared their features in support of terminal mobility, user mobility and service mobility, and then we analysised a multilayered mobility management scheme that integrate the MIP and MSIP altogether to provide a complete IP mobility management. We propose an effort direction for research the generalized mobility management techniques for NGN.
