说明：  共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。 在各种优化算法中，共轭梯度法是非常重要的一种。其优点是所需存储量小，具有步收敛性，稳定性高，而且不需要任何外来参数。(The Conjugate Gradient method is a method between the steepest descent method and the Newton method. It only needs to use the first derivative information, but overcomes the shortcomings of the steepest descent method and avoids the need for the Newton method to store And the calculation of Hesse matrix and the inverse of the shortcomings, conjugate gradient method is not only to solve large-scale linear equations one of the most useful methods, but also solution for large-scale nonlinear optimization of one of the most effective algorithm. In a variety of optimization algorithms, conjugate gradient method is a very important one. The advantage is that the required storage capacity is small, with step convergence, high stability, and does not require any external parameters.)

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。 ( On the basis of study of WiMfAX and SIP, a new mechanism using SIP to achieve end-to-end handoff under IEEE802.16e access networks is Ob proposed handoffs, in this thesis. The mechanism adopts a cross-layer design which means that the l}iIAC layer handoff procedure can interleaved with that of the application layer. During the handoff at link )
