在本文中，我们评估了地面通信系统与卫星网络无缝高效集成的可行性。 ETSI [1]、5G-PPP [2] 和 3GPP [3] 等标准化机构已考虑这一方面。在仿真原型中设计和实现了一个综合系统，包括标准 3GPP LTE 核心网络功能 [4] 及其不同层：网络、数据转发、控制、管理和监控，并通过性能测量进行验证。这项工作是一项技术可行性研究，旨在扩展以卫星网络作为回程的地面通信系统，提高自然灾害期间的能源效率和网络鲁棒性，并作为地面通信服务高峰时段数据转发的替代方案。由于其全球覆盖特性，地面卫星一体化为偏远地区提供了通信服务的明显延伸，并为农村或高度分布式/高度移动的企业网络提供了替代方案。
In this paper we evaluate the feasibility of seamless and efficient integration of terrestrial communication systems with satellite networks. This aspect is considered by standardisation bodies such as ETSI [1], 5G-PPP [2] and 3GPP [3]. A comprehensive system is designed and implemented in an emulation prototype, including standard 3GPP LTE core network functionality [4] with its different layers: networking, data forwarding, control, management and monitoring and is validated through performance measurements. This work is a technical feasibility study of extending terrestrial communication systems with satellite networks as backhaul, increasing the energy efficiency, network robustness during natural disasters as well as being an alternative for peak-time data forwarding of the terrestrial communication services. Due to its global coverage property, terrestrial-satellite integration provides an obvious extension of communication services towards isolated and remote areas and an alternative for rural or highly distributed/highly mobile enterprise networks.
