Abstract

The invention discloses a signaling analysis method and a signaling analysis system based on DVB-IPoS satellite communication. The signaling analysis method comprises the steps as follows: (a) getting MPEG2-TS frame data; (b) counting frame types and calculating the probability (PID probability) that frames of the same type appear; (c) setting a probability threshold, and selecting frame data within the threshold scope; (d) judging whether the selected frame data belongs to IPoS signaling data or not according to IPoS signaling data features, and jumping to step (f) if the selected frame data does not belong to IPoS signaling data; (e) analyzing system and network parameters in accordance with IPoS protocol rules; and (f) ending the process. Through the analysis method provided by the invention, the problem in traditional system signaling analysis based on DVB-IPoS satellite communication is solved. Meanwhile, in aspect of data processing in the analysis process, the screening efficiency is improved by setting a pre-screening mode. The set threshold effectively controls the balance between processing accuracy and processing efficiency, and the threshold setting method ensures the reliability of the threshold from the source.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a DVB-IPoS satellite communication signaling analysis method based on a non-cooperative communication mode and a corresponding analysis system. 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 can carry out mu...
