<P>PROBLEM TO BE SOLVED: To provide a network control apparatus etc. which can correctly decide an operation state of a plurality of communication apparatuses connected with a plurality of hierarchies without an effect from a trouble or power source OFF of an upper communication apparatus. <P>SOLUTION: The network control apparatus includes a LAN interface portion 102 to communicate with a plurality of communication apparatuses 2 through a LAN having a plurality of hierarchies, a power-saving wireless interface portion 103 to communicate with a plurality of communication apparatuses 2 through a power-saving wireless network, and a network control portion 101 which receives power source state information showing the power source state of the communication apparatus 2 from the communication apparatus 2 through the power-saving wireless interface portion 103, records the power source state of the communication apparatus 2 in the inside based on the information of the received power source state, sends the information of the network control to the communication apparatus 2 through the LAN interface portion 102, and checks the operation state of the communication apparatus 2 based on the response and the power-source state recorded inside. <P>COPYRIGHT: (C)2009,JPO&INPIT |
