The evolution of current wireless access networks towards 5G and beyond is characterized, among others, by the provisioning of high-bandwidth services and by the capability of serving traffic from a large number of heterogeneous devices. Among the key approaches for provisioning high capacity in such networks, a prominent role is played by network densification. However, dense deployments of many small cell base stations imply huge investments, increasing both CAPEX and OPEX for the mobile network. Additionally, densification increases the amount of over-provisioned network resources, due to variability in traffic demand over space and time.Following up recent research on connected cars, one of the most promising approaches to address these issues consists in exploiting vehicle-mounted small cell moving base stations. This allows taking advantage of the correlation between spatio-temporal patterns of users and of vehicles, in order to create a network that flexibly and naturally densifies whenever and wherever needed by many users, hence reducing the need for dense deployments of static base stations.The proposed concept constitutes a new paradigm for network design and operation, which seamlessly integrates static infrastructure with base stations operating on vehicles, with an unprecedented level of flexibility and adaptability. However, for such a moving network paradigm to effectively enable a dynamic and flexibly densified cellular network infrastructure, a number of key open research issues need to be addressed.The main goal of the DyMoNet project is to enable such moving network paradigm, by addressing some of the key open research challenges which stand in the way of its practical feasibility. Specifically, the project will aim at:(1) identifying those scenarios and use cases in which the moving network paradigm holds the highest potential to increase networking performance and resource efficiency with respect to traditional static deployments;(2) developing mechanisms for reliable wireless mobile backhaul, for the interconnection of moving base stations to the core of the network;(3) elaborating QoS-aware mechanisms for dynamic interference management, enabling an efficient provisioning of connectivity under tight QoS constraints; and (4) investigating dynamically resource allocation and slicing in order to satisfy specific QoS constraints, while accounting for the dynamics of service demand as well as of the moving network infrastructure.The outcomes of DyMoNet will advance the current state of the art in network planning and management, by providing new solutions for the design and the operation of future wireless access networks. Results will help assessing the potential of the moving network paradigm for enabling cost-effective and resource-efficient provisioning of communication services, offering technical inputs for economic evaluations, while removing some of the main technical obstacles to its implementation.

当前无线接入网络向5G及以后的演进的特征在于提供高带宽服务以及服务来自大量异构设备的业务的能力。在用于在这样的网络中提供高容量的关键方法中，网络致密化发挥了突出的作用。然而，许多小型小区基站的密集部署意味着巨大的投资，增加了移动的网络的CAPEX和OPEX。此外，由于交通需求在空间和时间上的变化，密集化增加了过度配置的网络资源的数量。继最近对联网汽车的研究之后，解决这些问题的最有前途的方法之一在于利用车载小型蜂窝移动基站。这使得可以利用用户和车辆的时空模式之间的相关性，以便创建一个可以随时随地灵活、自然地致密化许多用户需要的网络，从而减少对静态基站密集部署的需求。提出的概念构成了网络设计和运营的新范式，将静态基础设施与车辆上运行的基站无缝集成，具有前所未有的灵活性和适应性。然而，要使这种移动网络范式有效地实现动态和灵活的密集蜂窝网络基础设施，还需要解决一些关键的开放研究问题。DyMoNet项目的主要目标是通过解决一些阻碍其实际可行性的关键开放研究挑战，实现这种移动网络范式。具体而言，该项目将致力于：（1）确定移动网络范例相对于传统静态部署具有最大潜力来提高网络性能和资源效率的场景和用例;（2）开发可靠的无线移动的回程机制，用于移动基站与网络核心的互连;（3）详细说明用于动态干扰管理的QoS感知机制，使得能够在严格的QoS约束下有效地提供连接性; DyMoNet的研究成果将为未来无线接入网络的设计和运营提供新的解决方案，从而推动网络规划和管理的发展。研究结果将有助于评估移动网络模式的潜力，以实现具有成本效益和资源效率的通信服务提供，为经济评估提供技术投入，同时消除其实施的一些主要技术障碍。
