星地融合多场景应用及解决方案

Application Scenarios and Solutions of Satellite-terrestrial Integration

星地网络天然存在较强的互补性,为实现广域无缝覆盖,星地网络融合是未来网络演进的必然趋势。目前,受限于星地网络在体制、架构以及应用场景的差异性,星地网络融合程度较低。为快速推进融合网络发展,迫切需要开展星地融合场景与解决方案的挖掘探索。为此,提出了非地面网络与地面蜂窝网络协同应用场景以及潜在的增强方案,以实现星地网络资源的统一协调,提升资源利用率与用户体验,并进一步展望了未来星地融合网络发展前景。

Satellite network and terrestrial cellular network are complementary,and in order to achieve wide area seamless coverage,satellite-terrestrial integration network is the inevitable trend of network evolution.At present,due to the architecture,technology and application scenario,the two networks have not yet achieved integration.There is an urgent need to study scenarios and solutions in order to promote the development of satellite-terrestrial integration network.Therefore,a collaborative application scenario of non ground networks and ground cellular networks is proposed,as well as potential enhancement schemes,to achieve unified resources coordination of satellite-terrestrial integration network,improve resource utilization and user experience,and it further explores the future development prospects of satellite ground fusion networks.
