Research of Low Altitude Communication Protocol Conversion Process Based on Pattern Match

Abstract

For complex application layer protocol of low altitude communication system which may be implemented with several wireless communication technologies which include BeiDou Navigation Satellite System, 3G, Digital radio, GPS, ADS-B, etc., we design a low altitude communication protocol conversion process based on pattern match to enhance the capacity of low-altitude flight service stations processing multi-source information from low-altitude aircrafts or other stations. In the process, the application layer protocol of information is identified with the algorithm based on BM pattern matching and CAM multi-pattern matching fusion firstly, secondly, the common intermediate protocol information is produced, and target protocol information is generated finally.
