System-level simulation demonstration and verification system oriented to satellite mobile communication

Abstract

The invention provides a system-level simulation demonstration and verification system oriented to satellite mobile communication. Various basic models for users to build required satellite mobile communication system scenes can be provided for the users, and design requirements of the users for different network environments are met. The system comprises a simulation model base module, simulation function realization modules and a network collection management module. The simulation model base module is used for providing satellite mobile communication simulation models. The simulation function realization modules call corresponding simulation models from the simulation model base module to achieve the simulation function and each comprise three sub-modules including a network satellite mobile communication network topology management module, a satellite mobile communication link computation and mapping module and a satellite mobile communication protocol simulation module. The network collection management module is used for combining and scheduling the three sub-modules in each simulation function realization module so that the three simulation function realization modules can be matched to achieve the simulation function. The network satellite mobile communication network topology management module is subjected to wireless resource management.

Description

technical field [0001] The invention relates to the field of satellite mobile communication simulation, in particular to a system-level simulation demonstration verification system oriented to satellite mobile communication. Background technique [0002] In recent years, with the advancement of satellite technology, satellite mobile communication has played an increasingly important role in national defense construction, economic development, and social life. Satellite communication technology faces communication problems such as high delay and high fading that are different from ground communication systems. At the same time, compared with ground systems, satellite communication systems are expensive, complex in structure, and difficult to modify. [0003] Similar to ground communication systems, the development of satellite communication technology is also inseparable from the support of simulation test platforms. System-level simulation verification can quickly and low-co...

Problems solved by technology

[0009] Although these four simulation software have excellent simulation performance, there are insurmountable shortcomings when simulating satellite mobile communication solutions: NS2 lacks good support for DTN network environment

Moreover, in multi-node simulation, it can only simulate virtual data transmission, but cannot perform real data transmission, and cannot meet the requirements of satellite mobile communication simulation.
