摘要
面向未来,移动通信网络将具备"连接+"的通信服务能力,以及实现卫星通信和地面通信的系统级融合,因此提出一种集连接、智能、感知、计算、数据等多个要素于一体的星地融合网络架构.基于所提的网络架构,首先,探讨星地融合网络的组网关键技术,包括星地协同的智能管控技术、面向星地融合的高动态网络切片技术,针对用户业务对星地融合网络提出的差异化网络服务需求,对网络切片技术以及分布式自治技术的潜在发展形态展开讨论.然后,分析星载轻量化核心网技术.最后,通过自研的移动通信网络平台验证星地融合组网下的多业务网络切片共存以及轻量化核心网上星的可行性.
Abstract
For the future,mobile communication networks will have the ability to provide communication services with beyond connec-tivity,as well as to realize the system level integration of satellite communication and terrestrial communication,so an integrated satel-lite and terrestrial network architecture that included multiple elements such as connectivity,intelligence,sensing,computing,and data was proposed.Based on the proposed network architecture,several key technologies for satellite-terrestrial integration networking were discussed,included intelligent management and control technology for satellite and ground collaboration,a high dynamic network slic-ing technology for integrated satellite-terrestrial,and in response to the differentiated network service requirements of user services for integrated satellite and terrestrial network,the potential development patterns between distributed autonomous and network slicing tech-nologies were discussed.Then,onboard lightweight core network technology was introduced.Finally,the feasibility of multi-service network slicing coexistence and on-board lightweight core network were verified through a self-developed mobile communication net-work platform.
