Multi-mode VSAT (Very Small Aperture Terminal) satellite communication signaling parsing system and parsing method

Abstract

The invention discloses a multi-mode VSAT (Very Small Aperture Terminal) satellite communication signaling parsing system and a parsing method. The system comprises a signal receiving module and a data processing module, wherein the signal receiving module is used for receiving data forward and inputting the data into the system, and the data processing module is used for processing the data. The characteristics lie in that the system further comprises a frame type library, the frame type library is used for storing feature frames under different communication protocol modes, the feature frames are used for acting as a standard for judging whether data frames in the received data belong to data frames under corresponding communication protocols or not, and the judgment process is executed in the data processing module. The multi-mode VSAT satellite communication signaling parsing system provided by the invention is provided with the frame type library which can store multiple types of protocol feature frames, and screening and differentiation for different protocol type data are realized. Meanwhile, a new frame type write-in port and an original frame type modification port provided by the frame type library can enable frame types to be modified and corrected continuously and to be updated timely.

Description

technical field [0001] The invention relates to the technical field of VSAT satellite communication, in particular to a VSAT satellite communication signaling analysis system and analysis method with multiple mode analysis functions in a non-cooperative communication mode. Background technique [0002] Compared with other communication methods, satellite communication has the following characteristics: ①The communication distance is long, and the cost has nothing to do with the communication distance. Using geostationary satellites, the maximum communication distance is about 18100km. Moreover, the cost of building a station and the cost of operation do not change due to the distance between the communication stations and the harshness of the natural conditions on the ground between the two communication stations. This has obvious advantages over microwave relay, cable, optical cable, and short-wave communication in long-distance communication. ②Work in broadcast mode, and...

Problems solved by technology

However, the traditional VSAT satellite communication signaling analysis system usually only analyzes the signaling of a specific protocol mode, and the system has poor versatility and compatibility.
