The Research On Transmission Interference Period And The Development Of Test-Soft For GSM-R

On the basis of GSM, GSM-R is one of specifically systems for the railway. As the platform of the railway integrated communication, it has a great role for the application in the safety field, such as the train control etc. One of the key factors for the railway operation is the performance and quality of the network. To research the quality problem of the GSM-R network data transmission offering in the railway is of great important. This paper mainly describes the index of transmission interference rate during the Qos testing in the circuit domain and Guide the development and application of the testing software by analyzing the index.Chapter I Introduction briefly introduces the application status of the GSM-R in train control. Next, introduce the status of transmission interference rate.Chapter II Introduce the module and process of the GSM-R data transmission, then introduce the Qos and the key performance index. Finally analyze two parameter, end-to-end transfer delay and transmission interference rate.Chapter III Firstly introduces the protocol of the data link layer. Secondly focuses on the analysis of the transmission interference rate.Chapter V On the basis of the analyzing theory in previous chapters, this chapter introduces the design and development of the testing analysis software. At last attach a specific testing process as the demonstration.Chapters VI have a summary for this paper and the research direction for future.
