Abstract
The network system includes a controller () and a plurality of terminals (). The controller () sends a first request signal () which indicates a first limited time period defining a range within which the controller () receives signals respectively from the terminals () of which the number is identical to the maximum number of the terminals (). Upon receiving the first request signal (), the terminal () sends a first response signal () within the first limited time period. The controller () determines a total number of the terminals () on the basis of the number of the first response signals () received within the first limited time period, thereby determining a second limited time period defining a range within which the controller () receives signals respectively from the terminals () of which the number is identical to the total number of the terminals (). The controller () sends the second request signal () which indicates the second limited time period. Upon receiving the second request signal (), the terminal () sends a second response signal () within the second limited time period.
