A communication network system comprises: a first communication network including a wireless communication path; and a plurality of second communication networks each including a wireless communication path. Further, the communication network system has: a first terminal that uses the wireless communication path of the first communication network to perform a communication; and a second terminal that uses the wireless communication paths of the second communication networks to perform communications and that uses a communication path, which is different from the wireless communication paths of the second communication networks, to communicate with the first terminal. The second terminal comprises: a selection unit that selects a frequency of the second terminal to be used in the wireless communication paths of the second communication networks; and a determination unit that determines, at an opportunity of receiving given selection information from the first terminal, the frequency to be used in the wireless communication paths of the second communication network, and that instructs the selection unit to select the determined frequency. |
