The present invention increases accommodation efficiency in a wireless master station for wireless slave stations, and efficiently uses wireless resources while controlling traffic. In a communication system in which a plurality of wireless slave stations 2-1, 2-2, 2-3, . . . , perform wireless communication with wireless master stations 1-1 and 1-2 directly or through another wireless slave station and which performs communication from the wireless master stations with a collection control device 3 by means of wired communication or the like. The collection control device 3 stores first through fourth threshold values a, b, c, and d in memory, and makes efficient use while suppressing traffic by performing a “connection suppression notification”, a “specific high-frequency communication stop notification”, and an “accommodation refusal notification”, and performs functionality control through stages according to the number of accommodated wireless slave stations. |
