摘要：

According to the characteristics of both the station in passenger dedicated line (SPDL) and the GSM-R system, the basic conditions are established for modeling the train cell residence time distribution (TCRTD) within a GSM-R cell which covers a station in passenger dedicated line. In TCRTD model, there are four parts including non-stop train cell residence time distribution (with new call and handover call) and stop train cell residence time distribution (with new call and handover call). Given the radius of a GSM-R cell is 3 km and the speed of a train is 200~250 km·h-1, the simulation results are obtained which indicate that the TCRTD is obviously different from the mobile user cell residence time distribution which is usually modeled by negative exponential distribution or gamma distribution in public land mobile system. The TCRTD should be obtained by simulation under the real condition of both GSM-R system and SPDL.
