摘　　要：本文在对ＱｏＳ的柔性、描述和评价方法进行研究的基础上，针对频率资源有限的无线ＡＴＭ网，提出了利用ＱｏＳ的柔性在业务过程中对频率资源进行动态分配的方案和算法；并进行了实验仿真，结果表明利用ＱｏＳ的柔性动态分配频率资源可以提高资源的利用率。In this paper, a dynamic allocation scheme and algorithm for frequency resources utilizing flexible QoS during service process are proposed for wireless ATM networks with limited frequency resource, after some dis- cussion given on character, description and evaluation method of flexible QoS. Moreover, simulation condition and environment are described to estimate the performance of the proposed scheme. As simulation results are analyzed, it confirms that the WATM networks can achieve higher utilization in frequency resources with less lower QoS based on this scheme.
