摘要

为解决卫星网络面临的能耗与资源严重受限问题，提出一种基于RAN-CN融合的无状态轻量级星载网络架构。该网络通过基于服务化的RAN-CN功能融合重构实现网元功能的轻量化、借助网络功能无状态设计提升卫星网络的弹性、基于KubeEdge的方式实现卫星网络部署的轻量化3个方面，降低星载网络的资源占用，减少卫星网络系统流程的信令开销与处理时延。最后，通过自研实验平台完成对所提轻量级星载网络的有效性验证。

Abstract

To address the challenges of stringent energy and resource constraints in satellite network

this paper proposes a stateless and lightweight onboard satellite network architecture based on RAN-CN convergence. The satellite network achieves reduced resource utilization

lower signaling overhead

and decreased processing latency in system procedures through three key innovations: lightweight network functions realized by service-based integration and redesign of RAN-CN functions

enhanced elasticity of the satellite network enabled by stateless design of network functions

and lightweight and efficient deployment facilitated by the KubeEdge-based framework. Finally

the effectiveness of the proposed lightweight onboard satellite network is validated through experiments conducted on a self-developed testbed.
