摘要

针对卫星互联网建设初期高投入成本与运营收益不匹配的问题，对基于空地融合组网的6G非独立组网方案展开研究。提出了Overlay与Underlay融合的异构卫星互联网非独立组网方案，通过虚拟化技术将多轨道卫星网络抽象为统一资源池，并设计分阶段演进路径：初期依托5G核心网实现星地协同接入，中期下沉用户面功能降低时延，后期构建星地协同控制面实现全域资源调度。该方案通过分阶段架构演进实现了卫星网络与地面5G/6G核心网的深度协同，验证了异构资源虚拟化聚合和实时业务稳定性保障能力，为低成本构建天地一体化6G网络提供了可落地的技术路径。

Abstract

In view of the challenge of unmatched high cost investment and operating income at the initial stage of satellite Internet construction

the 6G non-standalone solution based on air ground integration was studied. A heterogeneous satellite Internet operation mode integrating Overlay and Underlay was proposed. The multi-orbit satellite network was abstracted into a unified resource pool through virtualization technology

and a phased evolution path was designed. In the initial stage

satellite ground cooperative access was achieved by relying on 5G core network. In the mid-stage

sinking user plane functions reduced the delay. In the last stage

satellite ground cooperative control plane was built to achieve global resource scheduling. This solution achieves deep collaboration between satellite networks and ground 5G/6G core networks through phased architecture evolution

verifying the ability of heterogeneous resource virtualization aggregation and real-time business stability guarantee

and providing a feasible technical path for low-cost construction of 6G space-air-ground integrated networks.
