Abstract: A wireless communication system includes an on-board terminal equipment mounted on a working machine, and a control server communicably connected together via a network including a first wireless base station and a second wireless base station. The control server sets a zone of a travel route as a travel-permitted zone, for which a travel permission has been given only to the working machine. A permission requesting zone in the travel-permitted zone, in which the working machine makes a setting request to the control server for a new travel-permitted zone, is set as a no-handover zone in which switching of the connected base station from the first wireless base station to the second wireless base station is prohibited. The on-board terminal equipment switches the first wireless base station to the second wireless base in a zone other than the no-handover zone in the travel-permitted zone.
