If there are trains with the same train number in the CTC system,the wireless route notice may be sent to a wrong train,which will cause confusion to the driver.To solve this problem,this paper proposes a solution to improve the wireless route notice transmission by the CTC system in GSM-R network covered sections.The proposed solution obtains the locomotive or EMU operation plan from the locomotive or EMU dispatching system through the CTC system.Then,it determines the leading locomotive's locomotive number or the EMU's train set number after matching with the actually received wireless train number information,to ensure that the CTC system sends the wireless route notice to the correct train.Thus,it can effectively prevent the incorrect transmission of wireless route notice by the CTC system without changing the wireless route notice transmission logic in the CTC system.
