Radio channel simulation system and method based on communication network

Abstract

The invention relates to the field of communication networks, in particular to a radio channel simulation system and method based on a communication network. A wireless channel of a radio station is simulated in an Ethernet mode, and modules such as a radio frequency interface of real radio station equipment are replaced in a network interface mode. A route simulation mode and a broadcast simulation mode are designed to realize the transmission process of wireless channel data. The system and the method have the beneficial effects that when radio station wireless channel data simulation forwarding is carried out in a network routing mode, simulation training during cross-routing network between semi-physical communication equipment can be realized, and capability range expansion such as cross-domain training of a training system is effectively supported; and when the broadcasting mode is adopted, the cost and the complexity can be effectively reduced, and the operation and maintenanceof the training system are more convenient.

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...

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
