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。
Mobility management and QoS assurance mechanisms are two key technologies in the all-IP mobile network. How to combine the two together to provide users with reliable and guaranteed services is undoubtedly a very important issue. In view of the shortcomings of RSVP not adapting to mobile environment and the micro-mobility protocol, this paper proposes a WDRSVP QoS solution in the micro-mobility domain of all-IP mobile network access network, and implements micro-mobility protocol and RSVP protocol interoperability between. The simulation proves that our method can effectively utilize the resources and can better guarantee the communication service quality of the mobile node during handover.
