中文摘要： 随着移动互联网的发展，飞速增长的无线数据流量和新业务不断挑战着无线网络的容量极限。为了提高无线网络的承载能力，蜂窝网络与无线局域网（WLAN）协同共存环境下宏小区、小小区和WLAN混合覆盖构成的分层异构融合网络将成为以用户体验为中心的下一代移动通信网络的典型场景。基于此场景，本项目将开展基于服务质量（QoS）保证和随机竞争的双机制协同下基于用户体验（QoE）的分层异构融合网络资源管理研究，从基础理论上突破。重点解决三个关键问题：1）用户信息需求密度在空域的不均匀性和时域的不确定性引起更严重的负载不均衡；2）蜂窝网络与WLAN协作不充分导致资源利用率低；3）资源与个性化的业务需求不匹配使得用户体验差。本项目将提出以用户体验为中心的分层异构融合网络组网的基本理论，这将为未来复杂多网环境下多制式网络协同融合组网的设计优化、资源共享和业务创新提供理论依据和支撑，具有重要的科学意义。

英文摘要： The data traffic of wireless network experiences a nonlinear and exponential growth; various kinds of new mobile Internet services emerge constantly, both of the above two phenomena pose a great challenge to the capacity of wireless network.To improve the bearing capacity of wireless network, the multi-layer heterogeneous integrated network (MHIN) becomes the future tendency. Consisting of macro cell, small cell and WLAN, MHIN will be the typical scenario for the Quality of Experience（QoE）-oriented mobile communication network in the next generation. The project aims to investigate the QoE-based radio management theory for MHIN under the QoS (Quality of Service)-aware and contention-based cooperatively scheduling. The project mainly solves three main challenges confronted by MHIN :1)the serious unbalanced load caused by user requirement's non-uniform distribution in space domain and uncertainty in time domain;2) the low utilizing efficiency of resources resulted from the insufficient cooperation between cellular network and WLAN;3)the poor QoE due to the mismatch between network resources and data requirement. This project will output the fundamental networking theory of QoE-oriented MHIN. It is anticipated the research outcomes will provide theoretical basis and technical guidance for the design and optimization of heterogeneous wireless networks under complex coexistence environments, and practically, promote radio resource sharing, network collaboration, service creation and energy efficiency improvement across multiple wireless networks. In a word, this project will have a profound scientific influence on the research of future wireless network.
