Train control system, base station control device, and ground wireless base station system
First Claim
1. A train control system comprising:
- an on-vehicle wireless station mounted on a following train following a preceding train and connected to an on-vehicle control device of the following train;
a plurality of ground wireless base stations configured to wirelessly communicate with the on-vehicle wireless station; and
a base station control device to control the ground wireless base stations, whereinone or a plurality of third ground wireless base stations are located between a first ground wireless base station that is the ground wireless base station with which the on-vehicle wireless station is communicating and a second ground wireless base station forming a communication area including a travelling permission point determined by a position of the preceding train for permitting the following train to travel to the travelling permission point, andthe base station control device includes;
a processor to execute a program; and
a memory to store the program which, when executed by the processor, performs a process of reserving radio resources of the second ground wireless base station and the third ground wireless base station while communicating with the first ground wireless base station.

Abstract
A train control system enabling a train to smoothly travel while performing handover. The system includes an on-vehicle wireless station mounted on a train following a preceding train and connected to an on-vehicle control device of the train, ground wireless base stations capable of wirelessly communicating with the on-vehicle wireless station, and a base station control device to control the base stations. The ground wireless base station is located between the ground wireless base station with which the on-vehicle wireless station is communicating and the ground wireless base station forming a communication area including a travelling permission point determined by a position of the train. The base station control device reserves radio resources of the ground wireless base stations while communicating with the ground wireless base station.

9. A base station control device in combination with a ground wireless base station system controlled by the base station control device, the ground wireless base station system comprising:
-
a first ground wireless base station in communication with an on-vehicle wireless station mounted on a train following a preceding train; a second ground wireless base station forming a communication area including a travelling permission point determined by a position of the preceding train for permitting the following train to travel to the travelling permission point; a plurality of third ground wireless base stations located between the first and second ground wireless base stations; the second and third ground wireless base stations being configured to communicate with the on-vehicle wireless station; the first, second and third ground wireless base stations having radio resources for allocation to the following train; and while the first ground wireless base station is in communication with the base station control device, the allocation of each of the radio resources of the second and third ground wireless base stations is reserved by the base station control device.
