综合地面-非地面网络（TN-NTN）是第六代（6G）连接在陆地、地球静止轨道（GEO）、中地球轨道（MEO）和低地球轨道（LEO）域中的关键使能者。然而，现有的NTN框架并未联合解决服务感知的服务域选择、多轨道协调和分层多流传输问题。本文提出了一种服务感知的多轨道速率分裂多址（SA-MO-RSMA）框架，该框架集成了全局公共、轨道公共和用户私有流，以及服务意图感知的服务域选择和资源编排。该框架作为系统级编排层运行于现有3GPP NTN架构之上。引入了一个多准则的轨道-服务效用函数（OSUF），以及服务连续性、切换稳定性、功率归一化传输效率和同步鲁棒性等指标。数值结果表明，与所考虑的基准方案相比，SA-MO-RSMA在平均每用户服务效用、服务连续性、切换稳定性和传输效率方面均有提升，展示了其在协调服务感知的多轨道TN-NTN运行中的潜力。
英文摘要
Integrated terrestrial--non-terrestrial networks (TN--NTNs) are a key enabler of sixth-generation (6G) connectivity across terrestrial, geostationary Earth orbit (GEO), medium Earth orbit (MEO), and low Earth orbit (LEO) domains. However, existing NTN frameworks do not jointly address service-aware serving-domain selection, multi-orbit coordination, and hierarchical multi-stream transmission. This paper proposes a service-aware multi-orbit rate-splitting multiple access (SA-MO-RSMA) framework that integrates global-common, orbit-common, and user-private streams with service-intent-aware serving-domain selection and resource orchestration. The framework operates as a system-level orchestration layer over existing 3GPP NTN architectures. A multi-criteria Orbit--Service Utility Function (OSUF) is introduced, together with metrics for service continuity, switching stability, power-normalized transmission efficiency, and synchronization robustness. Numerical results show that SA-MO-RSMA improves average per-user service utility, service continuity, switching stability, and transmission efficiency over the considered benchmark schemes, demonstrating its potential for coordinated service-aware multi-orbit TN--NTN operation.
