PROBLEM TO BE SOLVED: To facilitate the identification of correspondence connection relation between a node device and a user apparatus.SOLUTION: A network system 100 includes: multiple user apparatuses 120, 120, ...; and multiple node devices 110, 110, ... to be connected to the user apparatuses 120, 120, ... with cables. Radio communication is performed among the node devices 110, 110, .... Each node device 110 performs response confirmation with each user apparatus 120 connected to the node device 110 to thereby identify correspondence connection relation with the user apparatus 120 connected to the node device 110, and transmits correspondence connection relation to another node device 110. |
