随着各国月球探测任务的持续推进，地月通信已呈现网络化发展趋势。地月空间大尺度分布、高动态拓扑、强异构组网等特性，导致传统近地卫星网络技术难以适配，因此构建高效可靠的地月网络成为支撑深空探测任务的核心需求。本文旨在系统梳理地月网络研究进展，从网络架构与协议架构维度深入分析国内外相关研究成果与工程实践，重点探讨通信链路及网络构建、网络协议体系构建及优化、地月空间定位导航授时（Positioning, Navigation, Timing, PNT）、安全防护等关键技术体系。本文研究成果可为地月网络技术研发与工程实施提供参考，为载人登月、月球科研站建设等重大任务的信息保障体系构建奠定基础，助力推动地月空间探索与开发的规模化发展。

With the continuous advancement of lunar exploration missions by various countries, cislunar communications are increasingly evolving toward a networked paradigm. The unique characteristics of cislunar space—such as its vast spatial scale, highly dynamic topology, and strong heterogeneity in network composition—render traditional near-Earth satellite networking technologies inadequate. Consequently, establishing an efficient and reliable cislunar network has become a critical requirement for supporting deep-space exploration missions. This paper systematically reviews the research progress in cislunar networking. It provides an in-depth analysis of relevant domestic and international research outcomes and engineering practices from the perspectives of network architecture and protocol architecture. Key technical areas are emphasized, including communication link design and network construction, network protocol design and optimization, cislunar positioning, navigation, and timing (PNT), and security mechanisms. The findings of this study aim to serve as a reference for the development and implementation of cislunar networking technologies, laying the groundwork for information infrastructure to support major missions such as crewed lunar landings and the establishment of lunar research stations, thereby facilitating the large-scale exploration and utilization of cislunar space.
