星地协同智能海洋通信网络发展展望

Perspectives on coordinated satellite-terrestrial intelligent maritime communication network

随着国家海洋战略推进实施,海上运输、资源开发等经济活动日趋活跃,海洋通信需求不断增长。尽管地面蜂窝网络已进入5G时代,现有海洋通信仍主要依赖海事卫星和岸基通信手段,通信速率、通信时延和可靠性等远不能满足需求。未来6G网络有望实现天空地海全域覆盖,但由于海上环境的复杂性、海事业务的异构性等挑战,6G海洋通信网络仍面临特殊难题。在综述海洋通信现状的基础上,从传输效率、网络覆盖、信息服务3方面梳理关键技术。面向未来6G智能海洋通信网络发展,展望海上环境感知智能传输、星地协同动态组网和业务驱动资源分配技术方法与研究方向。

With the implementation of national marine strategy,economic activities such as maritime transport,marine resource exploitation become increasingly important,and the demand for maritime communications keeps growing.Although the terrestrial cellular network had entered the 5G era,existing maritime communications still mainly rely on marine satellites and shore-based base stations,which are far from meeting the demand in terms of communication rate,delay and reliability.The future 6G networks are expected to offer satellite-air-ground-sea full coverage.However,due to complex maritime environments and heterogeneous marine services,the 6G maritime communication networks still face unique challenges.After summarizing the current developing status of maritime communications,related key technologies were surveied from three aspects:transmission efficiency,network coverage,and information service.For the future development of 6G intelligent maritime communication networks,the technical methods and research directions of maritime environment-aware intelligent transmission,coordinated satellite-terrestrial dynamic networking and service-driven resource allocation were prospected.
