摘　　要：空中接入网(aerial access network, AAN)具有抗毁性强、覆盖范围广、视距传播概率高的特点,与地面网络相结合能够缓解流量负载压力,提供全时空的连接与服务,可有效助力第六代移动通信网络(6th generation mobile networks, 6G)“万物智联”愿景的实现.因此,在分析AAN中的卫星通信和高空平台(high altitude platform station, HAPS)技术研究进展的基础上,研究了卫星通信在数据接入方面的应用以及HAPS在一体化网络架构中的作用,探究了卫星与HAPS两种技术对未来网络的影响以及进一步优化二者的潜在方法.最后,对卫星接入的数据碰撞问题和HAPS的缓存问题进行讨论分析,并从上述问题出发展望了卫星通信和HAPS技术的未来发展方向.The air access network(AAN) has the characteristics of strong invulnerability, wide coverage and high line-of-sight propagation probability. Combined with the terrestrial network, it can effectively alleviate the traffic load pressure, provide all-time connection and services, and effectively contribute to the realization of the vision of “intelligence of everything” of the sixth generation mobile networks(6 G). Based on the analysis of satellite communication and high altitude platform station(HAPS) technology research progress in AAN, the application of satellite communication in data access and the role of HAPS in the integrated network architecture was studied, and further explores the effect of satellite and HAPS in future networks as well as the potential methods for optimization were explored. Finally, the data collision problem of satellite access and the cache problem of HAPS were discussed and analyzed, and the future development direction of satellite communication and HAPS technology was prospected from the above problems.
