A radio channel simulation system and method based on communication network

Abstract

The present invention relates to the field of communication networks, and more specifically relates to a radio channel simulation system and method based on communication networks. The wireless channel of the radio station is simulated through Ethernet, and the radio frequency interface and other modules of the real radio equipment are replaced by the network interface. Two ways of route simulation and broadcast simulation are designed to realize the transmission process of wireless channel data. Its beneficial effect is that when the wireless channel data simulation forwarding of the radio station is carried out in the way of network routing, it can realize the simulation training when the semi-physical communication equipment crosses the routing network, and effectively supports the expansion of the training system's ability range such as cross-domain training; When the method is carried out, it can effectively reduce the cost and complexity, and it is more convenient for the operation and maintenance of the training system.

Description

technical field [0001] The present invention relates to the field of communication networks, and more specifically relates to a radio channel simulation system and method based on communication networks. Background technique [0002] Generally speaking, a large-scale communication network has the characteristics of many types of equipment, a large number of equipment, and cross-use of wireless transmission equipment. The wired equipment of the communication network generally includes optical transceivers, switches, routers, etc., and the wireless equipment generally includes WIFI, radio stations, satellites, etc. Equipment, etc., among which there are many types of radio stations, including microwave communication stations, shortwave communication stations, ultrashort wave communication stations, etc. A general radio station has a characteristic that its communication channel is a broadcast communication channel without central control, while the communication channel constr...

AI Technical Summary

Problems solved by technology

However, the cost of real equipment is very high. It is designed with complex electromagnetic links, waterproof, anti-interference and other issues, and even has high-priced components such as radio frequency and antenna. It is difficult to use and maintain during training, and the equipment is easily damaged during training. Due to problems such as cost and mutual interference of wireless links, the solution of using real communication equipment cannot meet the needs of building a large-scale communication network training system

[0007] Combining the background technology and the development needs of the communication network training system, we can know that there are many excellent network simulation software to support network training and learning needs, but for some training customers, the operation is consistent with the actual installation, and the equipment structure layout is consistent, etc. The training needs need to be realized by relying on half-physical simulation equipment, while the simulation of wired networks is relatively simple, but it is more difficult to simulate wireless networks such as radio stations
