面向互联飞机的空天地网络一体化融合研究

The convergence technology of air-space-ground networks for connected aircraft

随着数字化技术的发展,民用飞机会在飞行各阶段产生大量数据,这些数据的利用及处理将提升飞机运营的经济性、安全性与舒适性。为了适应未来互联飞机对海量数据交换与传输的迫切需求,满足民用飞机对无线通信服务质量(QoS)的要求,有必要充分利用并合理分配多种现有和未来的空天地无线通信链路资源。分析了互联飞机的概念、生态系统及其对空天地网络的网络需求,研究了地面异构移动互联网采用的紧耦合和松耦合两种融合方法,采用了网络体系融合、IP网络和非IP网络融合及终端融合等多种融合手段,提出了适应于多种通信链路与网络体系特点的一体化空天地无线通信链路的融合架构,并对网络协议栈、网络安全以及集成验证提出了初步考虑。

With the development of digital technology, civil aircraft will generate a large amount of data at various stages of flight.The utilization and processing of these data will improve the economy, safety and comfort for aircraft operation.In order to meet the urgent requirements of future connected aircraft for massive data exchange and transmission, and to meet the Quality of Service(QoS) requirements of civil aircraft for wireless communication, it is necessary to make full use of and rationally allocate a variety of existing and future air-to-ground wireless communication link resources.This article analyzes the concept of connected aircraft, the ecosystem and its network requirements for the air-space-ground networks, researches the two convergence methods of tight coupling and loose coupling adopted by the ground heterogeneous mobile Internet, adopts a variety of integration methods such as the system integration, IP network and non-IP network integration, and terminal integration, proposes a convergence architecture of air-space-ground wireless communication links suitable for the characteristics of communication links and network systems, and the preliminary considerations for network protocol stack, network security, integration and verification were put forward.
