全IP移动网络基于弱动态资源预留的QoS保证机制

移动性管理和QoS保障机制是全IP移动网络中的两个关键技术。如何将二者结合起来，为用户提供可靠的有保障的服务，无疑是非常重要的问题。针对RSVP不适应移动环境的缺点，结合微移动协议，本文在全IP移动网络接入网的微移动域中，提出一种弱动态资源预留（WDRSVP）的QoS解决方案，实现微移动协议和RSVP协议之间的互操作。仿真证明，我们的方法能够有效地利用资源，能够更好地保证移动节点在切换时的通信服务质量。

A QoS Guarantee Mechanism Based on Weak Dynamic Resource Reservation in All-IP Mobile Network

Both mobility management and QoS provision mechanism are two key technologies in All-IP mobile network. Obviously,how to make them work together to supply users with reliable and guaranteed QoS service is an essential problem.Because RSVP is not applicable to mobile environment,this paper introduces a solution of in-advance Weak Dynamic Resource Reservation(WDRSVP)in micro-mobility domain of All-IP Wireless Access Networks,realizing the co-operation of micro-mobility protocols and RSVP.The simulation can prove that our method can make effective use of resources and guarantee the QoS of communications during the mobile nodes' handing off.
