摘要

摘要: 为研究客运专线区间上GSM-R(铁路移动通信系统)小区内列车信道占用时间和列车呼叫切换率等关键参数,建立了一种新的GSM-R小区内列车驻留时间分布模型.该模型假定GSM-R小区实际覆盖范围服从均匀分布,从而GSM-R小区内线路长度也服从均匀分布,并假定列车运行平均速度服从均匀分布.基于上述假定, 获得了模型的理论分析和仿真分析结果.研究表明,当GSM-R小区半径为3~8km 时,该模型的理论分析与仿真分析结果一致.

Abstract: In order to investigate the essential parameters in a GSM-R (global system for mobile communication for railway) system, such as train channel occupation time and train handover rate, a new distribution model of train residence time within a GSM-R cell in SPDL (section of passenger dedicated line) was established. This model is based on the hypotheses that path length and train's average speed within the GSM-R cell in SPDL follow uniform distributions, the former is deduced from the hypothesis that the GSM-R cell coverage submits a uniform distribution. From the above hypotheses, the theoretical and simulation results were obtained. The research results show that when the radius of a GSM-R cell in SPDL is between 3 to 8 km, the theoretical and simulation results of the distribution of train residence time within the GSM-R cell agree well.
