无定形超密集异构网络形态演化及动力学成因研究

The future mobile communication technologies target at providing user experiment oriented intelligent network. Amorphous ultra-dense heterogeneous network, which is based on de-cellular designing pattern and flexible networking, can fully meet the demand of growing traffic by offering high quality user experience, and is then deemed as one of the most promising research areas for the next generation of broadband green communications. Despite of all these advantages, the related research still remains in its initial stage. Our research conquers the collaboration barriers across the heterogeneous networks by establishing a unified theory of wireless resource virtualization, which lays the foundation for building a dynamic network. Besides, our research reveals that the essence of the emergence of the amorphous cells is the aggregation behavior of the smallcell base stations in the mesoscopic field under the relatively simple evolutionary game rules. Furthermore, the dynamic properties of the amorphous cells, such as the expansion, contraction, splitting, merging and so on, are characterized by the evolutionary dynamics equation. Finally, a complex and stable evolutionary equilibrium state, that is following the change of users’demand, is formed on the macro scale. Our research, which is developed from the micro, meso and macro level, is of great theoretical and practical value for the analysis of the evolution of the amorphous ultra-dense heterogeneous network.

未来移动通信技术的目标是构建面向用户体验的智能无线网络。无定形超密集异构网络秉承“去蜂窝化”网络设计范式，以柔性组网为基础，以高质量的用户体验满足未来移动通信对业务流量的增长需求，被视为新一代宽带绿色移动通信最具潜力的研究方向之一。但是目前其仍处在起步阶段，存在着挑战性的问题有待解决。本课题通过建立统一的资源虚拟化理论，破除异构网络的协作壁垒，为构建动态网络奠定基础。此外，本课题基于演化理论，揭示出无定形小区涌现的本质是微观上小小区基站以相对简单的演化博弈规则作用下在中观上显现出的聚集行为。更进一步，本课题通过演化动力学方程刻画无定形小区扩张，收缩，分裂，合并等动态特性，并最终在宏观上形成复杂而稳定的“伴随用户需求变化而变化”的演化均衡状态。本课题的研究从微观、中观、宏观三个层面展开对无定形超密集异构网络的演化理论剖析，具有重要理论意义和现实价值。
