The invention discloses a three-dimensional dynamic communication network analog simulation method, a three-dimensional dynamic communication network analog simulation system and a storage medium. Themethod comprises the following steps: establishing a communication network simulation project, and defining a communication network protocol and an equipment model; establishing a three-dimensional model project, defining a 3D entity, a 2D entity model and a three-dimensional terrain scene model, and generating a corresponding model file; newly establishing a simulation project, adding 3D entityand 2D entity model configuration parameters through the model file, and performing one-to-one mapping with NS3 node models in the communication network simulation project; and after the configurationof the simulation scene and the simulation parameters is completed, calling a communication network simulation simulator to operate simulation, and dynamically recording a simulation result. According to the embodiment of the invention, the editor, the compiler, the debugger, the engineering manager and the 2D / 3D visual display can be integrally realized, the operation is simple, and the interactive interface is friendly, so that the NS3 analog simulation system is more practical and has an industrial utilization value.
