为了提高容量并克服传统地面蜂窝无线网络的一些限制，可以部署带有空中基站的无人机（例如，以改善覆盖范围、缓解拥塞、支持溢出流量）。无人机的移动性允许灵活的网络重新配置，以适应动态的流量和信道条件。然而，这是以更多切换为代价实现的，因为即使是静态用户也可能在无人机移动时经历切换。在这封信中，我们对无人机基站网络的切换率和停留时间（两次后续切换之间的时间）进行了精确分析。我们还表明，在具有相同均值的不同速度分布中，当所有无人机基站以相同速度移动时，切换率最小。
To improve capacity and overcome some of the limitations of traditional terrestrial cellular wireless networks, drones with aerial base stations can be deployed (e.g., to improve coverage, alleviate congestion, support overflow traffic). The mobility of drones allows flexible network reconfiguration to adapt to dynamic traffic and channel conditions. However, this is achieved at the expense of more handovers since even a static user may experience a handover when the drones are mobile. In this letter, we provide an exact analysis of the handover rate and sojourn time (time between two subsequent handovers) for a network of drone base stations. We also show that among different speed distributions with the same mean, the handover rate is minimum when all drone base stations move with the same speed.
