摘　　要：提出了一种基于协同中继技术的异构网络融合方案,通过中继节点构建异构无线网络通信基础,采用协同通信的多向中继技术解决异构无线接入网间的传输瓶颈。进一步具体化结合无线局域网与蜂窝网络,研究其有效融合的场景和关键技术问题,提出可能的解决方案,兼顾室内数据高速率需求和室外高移动性要求,从而高性价比地提升用户体验质量。A heterogeneous network integration scheme based on cooperative relay .technology was proposed, then the foundation of heterogeneous network was conceived through the relay node, with the aim to solve the transmission bottleneck between heterogeneous wireless access network by using the muhidirectional relay technology, with the aid of cooperative communication. More specifically, based on WLAN and cellular networks, the effective integration and key technologies of the scene problems were investigated, then some possible solutions, with the purpose of meeting the indoor high data rate requirements and the outdoor high mobility requirements, so as to cost-effectively improve the quality of the user experience, were put forward.
