摘要

在IP网络中实现移动性是利用市场上出现的许多轻量级设备的一个重要问题。在IETF中标准化的IP移动性支持使用从本地代理到外部代理的IP数据包隧道，使移动性对更高层透明。与移动IP相关的问题有很多，例如三角形路由、每个主机需要一个家庭IP地址、隧道管理等。在本文中，我们建议在适用的情况下在应用层协议SIP中使用移动性支持，以便更有效地支持实时通信。

Mobility support using SIP

Enabling mobility in IP networks is an important issue for making use of the many light-weight devices appearing at the market. The IP mobility support being standardized in the IETF uses tunnelling of IP packets from a Home Agent to a Foreign Agent to make the mobility transparent to the higher layer. There are a number of problems associated with Mobile IP, such as triangular routing, each host needing a home IP address, tunnelling management, etc. In this paper, we propose to use mobility support in the application layer protocol SIP where applicable, in order to support real-time communication in a more efficient way.
