摘要

随着泛在宽带通信需求和星地通信技术的演进，卫星与地面蜂窝通信产业生态系统正逐步走向融合。为满足星地协同应用场景及技术需求，分析星地协同的接入网架构面临的主要技术挑战，基于连接动态、资源统一管控、地面控制的总体原则，从空间段、地面段及星地协同段阐述面向星地协同的接入网架构。从需求出发，基于所提网络架构提出对应的覆盖协同、业务协同、节能协同与测控协同的关键技术，通过设计智能动态协作网元、动态Xn接口、分布式测控单元等协同网元，星地两网深度交互有用信息，实现动态高效的星地协同机制，推动卫星网络与地面网络进一步互补，提高系统在资源利用率、能源消耗以及网络建设成本等方面的整体性能。

Abstract

With the development of ubiquitous and broadband communication requirements and the satellite-ground integration communication technology

the satellite and ground cellular communication industry ecosystem is gradually moving towards integration.In order to meet the application scenarios and technical requirements of satellite-terrestrial cooperation

the main technical challenges of the access network architecture were analyzed.Based on the overall principles of connection dynamics

unified resource management and controlled by ground network

the architecture of access network for satellite-terrestrial cooperation was elaborated from space segment

ground segment and cooperative segment.Key technologies of coverage cooperation

service cooperation

energy saving cooperation and capability cooperation were proposed based on the elaborated network architecture.By design cooperative network elements

such as intelligent dynamic cooperative unit

dynamic Xn interface

distributed TT＆amp;C units

the useful information between satellite and ground networks interacted deeply

a dynamic and efficient satellite-terrestrial cooperation mechanism could be realized.It could promote further complementarity between satellite and ground networks and improved overall system performance in resource utilization rate

energy consumption

and network construction cost.
