摘要
海洋移动通信网络在保障海上作业安全、提高海洋监测效率和促进海洋环境数据、海上基础设施状况等信息共享方面发挥着越来越重要的作用。然而,海洋环境的特殊性和通信需求的多样性给网络的无线资源管理带来了频谱资源有限、海洋动态环境适应等挑战。旨在探讨海洋移动通信网络中无线资源的智能管控策略,以提高网络性能和资源利用率,首先介绍了海洋移动通信网络的架构,包括空天地海一体化的海洋通信网络和海上协同组网,随后探讨了无线资源适配的关键技术,如数字孪生、网络切片、基于大语言模型的动态频谱共享技术等;最后讨论了海洋移动通信的信令切换流程、跳波束智能调度和动态边缘随机接入方法在移动性管理中的应用。通过这些策略,可以有效提高海洋移动通信网络的无线资源利用率和网络性能,对于构建高效、可靠的海洋移动通信网络具有重要意义。
Marine mobile communication networks are increasingly crucial for ensuring maritime operational safety,enhancing ocean monitoring efficiency,and enabling effective information sharing on ocean environmental data and maritime infrastructure status.However,the unique challenges of the marine environment and diverse communication demands create obstacles in wireless resource management,such as limited spectrum availability and the need to adapt to dynamic ocean conditions.This paper investigates intelligent wireless resource management strategies aimed at optimizing network performance and resource utilization in marine mobile communication networks.We first outline the architecture of these networks,including integrated space-air-ground-sea communication and collaborative maritime networking.Key wireless resource adaptation technologies are then examined,such as digital twins,network slicing,and dynamic spectrum sharing driven by LLMs.Additionally,we discuss mobility management applications,including signaling handover processes,intelligent beam-hopping scheduling,and dynamic edge random access techniques.Together,these strategies enhance wireless resource efficiency and network performance,providing a strong foundation for building efficient and reliable marine mobile communication networks.
