Currently, the coexistence of multiple users and devices challenges the network's ability to reliably connect them. This article proposes a novel communication architecture that satisfies the requirements of fifth-generation (5G) mobile network applications. In particular, this architecture extends and combines ultra-dense networking (UDN), multi-access edge computing (MEC), and virtual infrastructure manager (VIM) concepts to provide a flexible network of moving radio access (RA) nodes, flying or moving to areas where users and devices struggle for connectivity and data rate. Furthermore, advances in radio communications and non-orthogonal multiple access (NOMA), virtualization technologies and energy-awareness mechanisms are integrated towards a mobile UDN that not only allows RA nodes to follow the user but also enables the virtualized network functions (VNFs) to adapt to user mobility by migrating from one node to another. Performance evaluation shows that the underlying network improves connectivity of users and devices through the flexible deployment of moving RA nodes and the use of NOMA.

当前，多个用户和设备的共存挑战了网络可靠连接它们的能力。本文提出了一种新颖的通信体系结构，该体系结构可满足第五代（5G）移动网络应用程序的要求。特别是，此体系结构扩展并结合了超密集网络（UDN），多路访问边缘计算（MEC）和虚拟基础设施管理器（VIM）概念，以提供灵活的网络，可移动或移动的无线接入（RA）节点用户和设备为连接性和数据速率而奋斗的区域。此外，无线电通信和非正交多址（NOMA）的进步，虚拟化技术和能源意识机制已集成到移动UDN中，该移动UDN不仅允许RA节点跟随用户，而且还允许虚拟化网络功能（VNF）通过从一个节点迁移到另一个节点来适应用户移动性。性能评估表明，底层网络通过灵活部署移动RA节点和使用NOMA改善了用户和设备的连接性。
