Construction technology of 5G special test network for flight test

With the continuous deepening of the application of 5G technology in various industries, the aviation industry's flight test business is also accelerating the rapid transformation and upgrading of the 5G aviation test support model: deploying safe and reliable 5G networks in scattered test fields and laboratories, connecting test objects, basic test facilities, special test equipment, test engineers and management personnel, and information systems, effectively solving the new challenges encountered by existing test modes, Fully integrate 5G technology into cross factory and institute collaborative sharing of test data, and comprehensively break through barriers to data sharing and business collaboration between testing and flight testing. This paper focuses on aviation equipment flight test application, carries out research on the top-level architecture of 5G dedicated test and test network, proposes a 5G dedicated test and test network architecture for flight test, and introduces the wireless network, transmission network, core network architecture and edge computing scheme of dedicated 5G network in detail. Realize remote test monitoring and command collaboration in different locations, intelligent control of test sites, and rapid download of airborne collected flight test data; Establish a 5G network ecosystem for data sharing throughout the entire experimental process, support and optimize major business activities such as product design and development, production trial production, experimental verification, comprehensive support, and resource management. The 5G based testing and testing network is the first proposed in the domestic aviation testing field and also at a leading level in international testing system applications, which can be promoted and applied to other military testing fields.
