The Research Method Of Gsm-r System And Instance

With the rapid development china's railway and railway private mobile communications technology and information to underline the importance of the railway. railways are increasingly integrated digital mobile communications system(GSM-R).system is on the increase in the railway communication facilities and environment suitable for high speed to use the system is specially aims at the railway to mobile communications needs a dedicated system.Due to the GSM-R system technology involved in more integrated with chinese characteristics of the railway communication, and it belongs to the railway in new technology in China.It demands for testers, to be familiar with technology and GSM-R to have a wealth of experience in railway communication.Based on the above considerations, the article first discuss the the system of hardware, then the network for GSM-R the layer, hardware, and service quality parameters for (QOS). The internet test the emphasis of the wireless a strong radio interference with the environment, the two important GSM-R network indicators of the test, and the relevant data analysis. Then analyze the hardware and system of terminals test indicators, which has chosen the BCS,TRAU,VGCS, and voice calls for a series of specific hardware and application of examples. For these network and hardware test, natural birth to mention the subject of GSM-R quality of service testing analysis. Research and analysis as GSM-R network construction of the frequency distribution or the base station while addressing the opening stage of the system, the test, parameters, configuration, and performance optimization, check and acceptance of construction stages for the dynamic test Finally provides for a test project to be expressed which I had taken part in so as to illustrate.
