RESEARCH_ON_END-TO-END_HANDOFF
说明： 本文在研究IEEE802.16e协议和SIP协议的基础上，提出了利用
SIP解决IEEE802.16接入网络中端到端切换的新方案。该方案采用跨
层切换的设计思想，联合MAC层和应用层SIP协议，在底层链路切换
的同时，完成应用层会话的修改，加快了切换过程，减少了切换时延，
提高了切换成功率。本文基于NS2仿真平台，完成了相应的仿真平台
搭建过程，实现了SIP协议模块和WiMAX协议模块的融合，扩展了SIP
协议模块的部分消息，最终在基于SIP协议模块和WiMAX协议的统一
NS2平台上实现了基于WiMAX接入、支持SIP扩展功能的SIP会话建
立和修改过程。
