Abstract

Abstract : According to the standard for the GSM for railway (GSM‐R) wireless systems in China train control system level 3 (CTCS‐3), the control data transfer delay should be no larger than 500ms with greater than 99% probability. Coverage of both non‐redundant networks and intercross redundant networks and cases of single Mobile terminals (MTs) and redundant MTs on one train are considered, and the corresponding vehicle‐ground communication models, delay models, and fault models are constructed. The simulation results confirm that the transfer delay can meet the standard requirements under all cases. In particular, the probability is greater than 99.996% for redundant MTs and networks, and the standard of transfer delay in CTCS‐3 will be improved inevitably.
