Abstract:
1. A data processing system including a first data processing apparatus that receives wireless communication data sent from a wireless terminal, and second data processing apparatus that receives wireless communication data sent from the wireless terminal and that communicates with the first data processing apparatus via a wired network, the data processing system comprising: the first data processing apparatus including, a first wireless communication unit configured to receive from the wireless terminal a shift request for shifting the second data processing apparatus from a first status incapable of receiving the wireless communication data to a second status capable of receiving the wireless communication data; and a first wired communication unit configured to, responsive to the first wireless communication unit receiving the shift request, send a shift signal for shifting the second data processing apparatus from the first status to the second status to the second data processing apparatus via the wired network; and the second data processing apparatus including, a second wireless communication unit configured to receive wireless communication data from the wireless terminal; a second wired communication unit configured to receive the shift signal sent by the first wired communication unit from the first data processing apparatus via the wired network; and a status shift unit configured to, responsive to the second wired communication unit receiving the shift signal, shift the second data processing apparatus from the first status to the second status, wherein the first data processing apparatus further comprises, a determining unit configured to determine whether a third data processing apparatus operating in the second status exist on the wired network in a case where the first data processing apparatus shifts from the second status to the first status; and a control unit configured to enable the first data processing apparatus to shift from the second status to the first status in a case where the determining unit determines that the third data processing apparatus exists, and to disable the first data processing apparatus to shift from the second status to the first status in a case where the determining unit determines that the third data processing apparatus does not exist, wherein, when the second data processing apparatus has shifted from the first status to the second status, the second wired communication unit sends a notification signal indicating that the second data processing apparatus has shifted from the first status to the second status to the first wired communication unit via the wired network, and wherein responsive to the first wired communication unit receiving the notification signal, the first wireless communication unit notifies the wireless terminal that the second data processing apparatus has shifted from the first status to the second status.
