Xi’an GSM-R Network Performance Analysis And System Optimization

China GSM-R network is developing by the passenger dedicated line, and carriedthe train control message, voice calls, dispatching command transmission, Wirelesstrain number transmission wireless communication services. GSM-R was alsoidentified as the existing national rail lines of the original wireless systemtransformation goals. Zhengzhou-Xi’an high-speed rail in particular the GSM-Rnetwork to carry the CTCS-3train control information transfer services for GSM-Rnetwork flow and a higher safety requirements.In this paper, the definition and calculation method through the study of GSM-Rnetwork performance analysis, identify key performance indicators (such as channelavailability, connection rate, congestion rate, call drop rate, handover successrate, network coverage, etc.), combined with GSM-R equipment maintenance manualinstructions, the GSM specification defines the parameters into "COUNTER"computing network mapping, or specific indicators also discussed relations"COUNTER" with a network problem, a GSM-R network in Xi’an wireless performanceindicators method of statistical computing and discusses the wireless networkoptimization methods, processes and content。...
