中文摘要： 无线接入网络的能效问题是未来移动通信需要研究的方向之一。从能效优化的要求来说，为了与用户业务需求相匹配，网络提供的服务能力需要具有多维时变的特征；同时异构性又是未来无线网络的主要特征之一，网络之间的差异性使得网络提供的服务能力缺乏能效评估准则，造成能效优化的困难。针对上述问题，项目组引入具有多维时变表征能力的泛函级数理论，利用核函数表征业务的服务质量需求，在核函数构成的正交空间中，利用范数理论、矩阵分析等相关数学方法，建立能够有效揭示网络服务能力特征的系统能效泛函级数模型；并在该模型基础上，利用向量代数理论研究新用户接入时的网络调度问题，利用统计拟合方法研究用户移动导致的网络切换问题，为无线网络的能效优化问题提供一种新的研究思路和方法，推动我国在无线网络领域的绿色自主创新研究。

英文摘要： The energy efficiency of wireless access networks is one of the most important research areas of future mobile communications. To satisfy optimization requirement of energy efficiency, the network service ability need to have multi-dimensional time-varying characteristics for matching with the traffic characteristic. Moreover, the heterogeneity is one of main features of the wireless access networks in the future, the heterogeneity of various wireless access networks results in lacking of evaluation criteria on the network service ability and the difficult in energy efficiency optimization. To solve these problems, this project introduces the functional series theory which has the multi-dimensional time-varying characteristic, and denotes the quality of service of traffic by kernel functions of functional series. In the orthogonal space built by kernel functions, mathematics methods, such as norm theory and matrix analysis, are used to establish the functional series models on the energy efficiency of wireless access networks which can reveal traffic characteristics of wireless access networks. On the basis of proposed models, the project will use vector algebra theory to study the network scheduling problem when a new user accesses networks, and will use statistical approximation method to analyze the network s
