Abstract

LTE-M system is proposed to be used in the next generation of rail transit communication based train control (CBTC) system to achieved at a communication between the way side and vehicles. Such communications require low delay of data transit. Communication of vehicle terminal accessing the base station is modeled as M/M/1/m/m in the queuing theory. A method is developed to predict probability of data transit delay when LTE-M is used in CBTC. Related conditions are presented to meet the CBTC requirements. This study provides a reference for reliability design of the LTE-M system in the future.

Key words： rail transit; communication based train control (CBTC); long term evolution-metro (LTE-M); queuing theory; communication delay
