摘　　要：无人机因其环境、民用和军事应用而受到广泛关注。由于其低成本和部署灵活性,具有通信功能的无人机有望在5G、6G移动网络等领域发挥重要关键作用。然而,诸如无人机在高空的自由空间传播行为,以及暴露于天线旁瓣等变量,可能会导致无线电环境的变化。无人机网络中有限覆盖区域的错误传输,可能会出现更多问题,例如频繁切换。由于无人机特性的这些差异,在未来移动网络中的部署将面临与移动性和切换过程有关的关键技术问题。因此,无人机网络需要更高效的移动性和切换技术,以持续保持稳定可靠的连接。本文综述了移动通信网络中互联无人机切换管理方面的大量研究,强调了实现互联无人机所面临的与切换相关的挑战。Drones have received widespread attention due to their environmental,civilian,and military applications.Due to its low cost and deployment flexibility,unmanned aerial vehicles with communication capabilities are expected to play a crucial role in 5G,6G mobile networks,and more.However,variables such as the free space propagation behavior of drones at high altitudes and their exposure to antenna sidelobes may lead to changes in the radio environment.The erroneous transmission in limited coverage areas in drone networks,more problems may arise,such as frequent switching.Due to these differences in drone characteristics,the deployment of drones in future mobile networks will face key technical issues related to mobility and switching processes.Therefore,the drone network requires more efficient mobility and switching technology to continuously maintain stable and reliable connections.This article reviews a large amount of research on handover management of interconnected drones in mobile communication networks,emphasizing the challenges related to handover faced by implementing interconnected drones.
