中文摘要： 近年来，移动互联网的业务类型层出不穷，其业务量不断增长，给无线通信系统提出了巨大的挑战。为了有效利用有限的无线资源给用户提供高质量业务体验质量(QoE)，有必要研究面向QoE的无线网络资源优化和设计。 首先，综合考虑多个客观因素以及用户主观因素，本课题提出采用统一的无线业务体验质量评价方法，通过自学习获得各种无线业务的QoE模型。然后，利用随机Petri网对无线网络的动态行为进行建模分析，并结合前述的QoE评价模型，构造无线资源分配的优化问题；同时，对优化问题进行合理转化并求解。通过本课题的研究，可为多业务无线网络如何提高用户业务体验质量提供重要的理论指导。

英文摘要： With the rapid development of mobile Internet, the types and amount of services have significantly increased recently, which pose the great challege to wireless communication systems . In order to effieciently explore the limited wireless resources and provide the good quality of experience (QoE) to users, it is necessary to study the QoE-aware wireless resource allication optimzation. Firstly, considering the effects including multiple objective and subjective factors, we propose to use an unified framework for evaluating the quality of wireless services, and QoE evaluation models for typical services can be obtained by the self-learning process. Next, the dynamic behavior of wireless network is analyzed by applying stochastic Petri net theory, which can be used together with the QoE model to build up the optimization problem. Moreover, the optimization problem may be transformed and finally be solved. Our research can provide the essential theoretical guide in improving the QoE performances in wireless networks with multi-services.
