With the skyrocketing number of connected devices and dramatic growth in data traffic, terrestrial networks alone cannot meet the massive and global connectivity needs in an effective and efficient manner. It is envisioned that airborne and space communication infrastructures, such as low Earth orbit (LEO) satellite constellations and unmanned aerial vehicles (UAVs), will be integrated with terrestrial networks to provision more comprehensive and three-di-mensional network connectivity, anywhere and anytime. As the fundamental information infrastructure, space-air-ground integrated networks (SAGINs) will also provision ubiquitous communication, computation, and caching to achieve high data rate, low latency, and high reliability.

客座社论：面向服务的空空地面综合网络

随着连接设备数量的激增和数据流量的急剧增长，仅地面网络已无法有效有效地满足大规模和全球连接的需求。可以预见，诸如低地球轨道（LEO）卫星星座和无人飞行器（UAV）等机载和空间通信基础设施将与地面网络集成在一起，以便随时随地提供更全面，三维的网络连接。作为基础信息基础架构，空空地面集成网络（SAGIN）也将提供无处不在的通信，计算和缓存，以实现高数据速率，低延迟和高可靠性。
