A QoS Guarantee Mechanism Based on Weak Dynamic Resource Reservation in All-IP Mobile Network
全IP移动网络基于弱动态资源预留的QoS保证机制

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.
