On-board equipment comprising: a wireless communication device, configured to receive a switching instruction from a ground responder; a time management device, configured to determine a wireless time-out time slice after the wireless communication device receives the switching instruction from the ground responder, the wireless time-out time slice being a longest time period of pause communication on a premise that the wireless communication device keeps communication with a zone controller, ZC, wherein as long as a time period during which the communication between the wireless communication device and the ZC pauses is less than or equal to the wireless time-out time slice, the wireless communication device can resume a communication state and communication contents with the ZC before communication pause, and continue communication with the ZC, wherein the wireless communication device is further configured to: pause communication with a handover ZC during a wireless time-out time slice and within a range of a current movement authority, establish communication with a takeover ZC during a next wireless time-out time slice and report a train position to the takeover ZC, and to pause communication with the takeover ZC when the next wireless time-out time slice comes to an end; a storage device, configured to store communication contents between the wireless communication device and the takeover ZC when the wireless communication device pauses communication with the takeover ZC; and a processing device, configured to determine a next movement authority according to the communication contents between the wireless communication device and the takeover ZC, determine whether the current movement authority is connected with the next movement authority, and perform zone switching if a determination result is yes wherein the current movement authority is connected with the next movement authority when the route corresponding to the current movement authority and the route corresponding to the next movement authority are partially overlapped with each other or exactly connected with each other seamlessly. a wireless communication device, configured to receive a switching instruction from a ground responder; a time management device, configured to determine a wireless time-out time slice after the wireless communication device receives the switching instruction from the ground responder, the wireless time-out time slice being a longest time period of pause communication on a premise that the wireless communication device keeps communication with a zone controller, ZC, wherein as long as a time period during which the communication between the wireless communication device and the ZC pauses is less than or equal to the wireless time-out time slice, the wireless communication device can resume a communication state and communication contents with the ZC before communication pause, and continue communication with the ZC, wherein the wireless communication device is further configured to: pause communication with a handover ZC during a wireless time-out time slice and within a range of a current movement authority, establish communication with a takeover ZC during a next wireless time-out time slice and report a train position to the takeover ZC, and to pause communication with the takeover ZC when the next wireless time-out time slice comes to an end; pause communication with a handover ZC during a wireless time-out time slice and within a range of a current movement authority, establish communication with a takeover ZC during a next wireless time-out time slice and report a train position to the takeover ZC, and to pause communication with the takeover ZC when the next wireless time-out time slice comes to an end; a storage device, configured to store communication contents between the wireless communication device and the takeover ZC when the wireless communication device pauses communication with the takeover ZC; and a processing device, configured to determine a next movement authority according to the communication contents between the wireless communication device and the takeover ZC, determine whether the current movement authority is connected with the next movement authority, and perform zone switching if a determination result is yes wherein the current movement authority is connected with the next movement authority when the route corresponding to the current movement authority and the route corresponding to the next movement authority are partially overlapped with each other or exactly connected with each other seamlessly.
