论文摘要
移动性管理是蜂窝网络的关键特征。当将无人机(UAV)集成到蜂窝网络中时,需要仔细管理其细胞关联,以与其他蜂窝用户共存。无人机在三个维度上移动,并可能在其飞行路径上遍历几个单元,因此可能会受到多种切换。为了使与无人机用户进行有关移动性管理的研究,本文描述了与空中用户进行切换实验的设计,实现和测试方法。我们利用软件定义的收音机(SDR),并实施一系列工具来准备实验室中的实验并将其在户外进行现场测试。我们使用仅商业现成的硬件,开源软件和实验许可来启用可重现和可扩展的实验。我们的初始室外结果与两个SDR基站连接到开源软件核心网络,实现4G长期演变协议,一个低空无人机用户设备展示了移交过程。
Mobility management is the key feature of cellular networks. When integrating unmanned aerial vehicles (UAVs) into cellular networks, their cell association needs to be carefully managed for coexistence with other cellular users. UAVs move in three dimensions and may traverse several cells on their flight path, and so may be subject to several handovers. In order to enable research on mobility management with UAV users, this paper describes the design, implementation, and testing methodology for handover experiments with aerial users. We leverage software-defined radios (SDRs) and implement a series of tools for preparing the experiment in the laboratory and for taking it outdoors for field testing. We use solely commercial off-the-shelf hardware, open-source software, and an experimental license to enable reproducible and scalable experiments. Our initial outdoor results with two SDR base stations connected to an open-source software core network, implementing the 4G long-term evolution protocol, and one low altitude UAV user equipment demonstrate the handover process.
