[0021] The system architecture of the present invention is as follows Figure 1 .

[0022] The system consists of two modules: protocol stack and scenario simulation module, and status monitoring and display module.

[0023] Protocol stack and scenario simulation module: mainly composed of communication terminal model, business management station (mainly business management station communication equipment) model, command post model (mainly command post communication equipment) and satellite (mainly satellite communication equipment) model, and realizes the simulation model and scenario model of each part of the protocol stack on the OMNeT++ platform.

[0024] Status monitoring and display module: Visualize the data obtained from the simulation to display the network status and various network performance indicators.

[0025] Simulation scenario scale: command post (1), business management station (1), satellite (1), communication terminal (2).

[0026] For the network protocol stack of scene interaction, it is divided into physical layer, link layer and network layer. The interactive connection diagram is as follows Figure 2 .

[0027] The whole system simulation flow chart is as follows: Figure 3 .

[0028] The process is divided into the following stages: 1. Preparation stage: (1) Command Post: Mission assumptions include setting the starting and destination locations, starting time, communication resources, etc., and issuing the assumed mission (the mission that needs to be set) to the business management station.

[0029] Based on the resource feedback from the business management station, adjust the task assumptions and issue the task start order.

[0030] (2) Business Management Station: Follow the path between the starting point and the destination to find relevant resources, evaluate resource availability, provide feedback to the command post, and configure resources according to the mission launch command.

[0031] (3) Communication terminal: wait.

[0032] (II) Startup phase (the entire simulation system, including the command post, business management station, and communication terminal, begins to load simulation resources and start configuration: (1) Communication terminal: The communication resources and start time along the way are uploaded to the communication terminal and business management station through the ground loading port.

[0033] (2) Business Management Station: Configure resources.

[0034] (3) Command Post: Startup time.

[0035] (III) Working time stage (begin to simulate the communication process between the command post, business management station and communication terminal): (1) Communication terminal: The network access process is carried out according to resource allocation, and communication resources are added in the air. The communication terminal communicates with the business management station via satellite, and finally completes the mission (the preset interactive information transmission task between the business management station and the communication terminal is completed).

[0036] (2) Business Management Station: The network access process is carried out according to resource allocation, network access management is completed, and communication resources are added in the air. The communication terminal communicates with the business management station via satellite and finally completes the mission.

[0037] (3) Command Post: The command and control instructions are sent, so that the business management station completes the network access management and the communication terminal completes the network access.

[0038] (IV) Ending stage: (1) Communication terminal: After the task is completed, the information is cleared.

[0039] (2) Business Management Station: After the mission is completed, feedback is sent to the command post and the information is cleared.

[0040] (3) Command Post: The command and control communication terminal completes the final task and then clears the information.

[0041] Figure 3 The workflow and interaction of each module in the simulation system are clarified, which can effectively guide the development and deployment of the actual system.

[0042] The present invention is based on the efficient simulation architecture design of the OMNeT++ platform: The present invention develops a simulation test architecture for communication terminals based on the OMNeT++ platform, which can simulate and test the performance of communication terminals in complex network scenarios without relying on the real network environment. Compared with the traditional method of relying on actual hardware conditions for testing, it reduces hardware dependence and testing costs, and effectively improves development efficiency and simulation flexibility.

[0043] The present invention proposes a simulation model of a cross-layer collaborative mechanism: Based on the traditional layered simulation model, the present invention introduces a cross-layer collaborative mechanism module to realize information interaction and joint simulation between the physical layer, link layer and network layer. By sharing state information and collaborative scheduling strategies at different levels, the linkage of each layer of the protocol stack is improved, making the simulation model more realistic and accurate, and able to simulate complex cross-layer interaction behaviors.

[0044] The present invention designs a simulation function for complex interactive behaviors of multiple nodes: the simulation system described in the patent is able to handle complex interactive behaviors between multiple communication terminals, command posts, business management stations, and satellites. In the simulation scenario, the communication process between nodes can be effectively simulated, including multiple stages such as mission assumptions, resource allocation, network access management, information transmission, and mission completion. The simulation of such complex interactive behaviors is often difficult to achieve in traditional simulation platforms due to performance bottlenecks, but the present invention solves this problem by optimizing the architecture design.

[0045] The present invention realizes the visualization and dynamic optimization of simulation data: the present invention designs a real-time dynamic display and optimization module, which can display the network status and performance indicators generated during the simulation process to the user in a visual manner. This not only improves the intuitiveness of data analysis, but also through the dynamic optimization of simulation data, the simulation scene configuration can be adjusted in real time to obtain more accurate simulation results, providing a more effective reference basis for system design and development.

[0046] The present invention realizes an automated simulation process and reduces manual configuration: The present invention designs an automated simulation process, covering four stages: preparation, startup, working time, and end. During the simulation process, all resource configurations and task instructions are automatically completed by the system, without the need for a large amount of manual configuration, which greatly reduces the workload and improves the simulation efficiency and accuracy.

[0047] As described above, the present invention can be preferably implemented.

[0048] All features disclosed in all embodiments in this specification, or steps in all methods or processes implicitly disclosed, except for mutually exclusive features and / or steps, can be combined and / or expanded or replaced in any manner.
