中文摘要：

在交流终端的异质需要通过支持软件的改编被处理。即时动态改编带更多的时间不得已地花费了的系统。在这篇论文，我们为用户承认控制建议 QoS 评价前；系统负担控制。反馈充当预先估计模块的输入参数的调解员。我们评估我们的途径的现在的测试结果。测试结果证明我们的服务质量控制机制是有效的。

英文摘要：

The heterogeneity in the communicating terminals needs to he handled through software-supported adaptation, The real-time dynamical adaptation brings the system more time cost unavoidably. In this paper, we propose QoS pre-estimation for user admission control and system load control. Feedback acts as adjuster of the input parameters of the pre-estimate module. We present tests results to evaluate our approach, The test results show that our service quality control mechanism is effective.
