随着全球通信需求的增长,星载核心网不仅可以减少星地间频繁的信令交互,更能突破地理区域的束缚,为天地融合网络架构以及全球通信运营提供有力支撑。然而,由于卫星的资源限制以及大尺度动态时变的卫星互联网动态拓扑结构,传统的核心网网元在星载环境下的部署遭遇了极大挑战。致力于研究低轨大规模星座下星载核心网的轻量化、灵活部署和低时延的挑战,旨在探索星载轻量化核心网的新型设计策略,为全球化的通信运营提供坚实的理论基础。首先研究包括最小网元集部署、单网元功能裁剪、接口协议轻量化、网元的融合与重构、平台架构轻量化以及传输协议重构等多个轻量化策略。然后,对选定的策略进行仿真实验,实验结果证实轻量化处理后的星载核心网在资源配置和信令流程方面均具有优越的性能表现。
With the growth of global communication demand
the spaceborne core network can not only reduce frequent signaling interactions between satellites and the ground
but also break through the constraints of geographical regions
providing strong support for the integrated network architecture of heaven and earth and global communication operations.However
due to the resource limitations of satellites and the dynamic and time-varying topology of satellite internet on a large scale
the deployment of traditional core network elements in spaceborne environments has encountered significant challenges.This article is dedicated to studying the challenges of lightweight
flexible deployment
and low latency in onboard core networks
aiming to explore new design strategies for onboard lightweight core networks and provide a solid theoretical foundation for global communication operations.Multiple lightweight strategies
including minimum network element set deployment
single network element function tailoring
interface protocol lightweight
network element fusion and reconstruction
platform architecture lightweight
and transmission protocol reconstruction were firstly studied.Then
detailed simulation experiments were conducted on the selected strategies
and the experimental results confirmed that the lightweight processing of the spaceborne core network has superior performance in resource allocation and signaling process.
