摘要

在现代无人机上部署LTE网络需要重新设计LTE架构的关键组件。在本文中,我们提出了一种激进的边缘EPC设计,称为SkyCore,它将其核心功能之一,即其演进分组核心(EPC)推向LTE网络的极端边缘,将EPC分解为一个单一的、轻量级的、自包含的实体,与每个无人机基站位于同一位置。SkyCore集成了一些元素,旨在解决无人机环境中分布式设计所面临的独特挑战,即无人机平台的资源约束性质,以及无人机和用户移动性的分布式管理。我们在多无人机LTE网络上构建和部署了一个全功能的SkyCore系统,并展示了其(i)与商用LTE基站以及智能手机互操作的能力,(ii)支持热点和独立多无人机部署,以及(iii)与其他EPC变体相比,在这个固有的动态,不可靠的环境中具有强大的控制和数据平面性能。

Skycore: Moving Core to the Edge For Untethered and Reliable UAV-Based LTE Networks
Deploying LTE networks on modern UAVs requires a redesign of the key components of the LTE architecture. In this article, we propose a radical, edge-EPC design, called SkyCore, that pushes one of its central functionalities, namely its evolved packet core (EPC) to the extreme edge of the LTE network - collapses the EPC into a single, lightweight, selfcontained entity that is co-located with each of the UAV base-stations. SkyCore incorporates elements that are designed to address the unique challenges facing such a distributed design in the UAV environment, namely the resource-constrained nature of UAV platforms, and the distributed management of UAV and user mobility. We build and deploy a fully functional SkyCore system on a multi-UAV LTE network and showcase its (i) ability to interoperate with commercial LTE basestations as well as smartphones, (ii) support for both hotspot and standalone multi-UAV deployments, and (iii) robust control and data plane performance compared to other EPC variants in this inherently dynamic, unreliable environment.
