PROBLEM TO BE SOLVED: To provide the method for reserving a band of wait permission type where it is not required to repeat a 2nd request till a band requested by the user is reserved so as to suppress needless traffic for the 2nd request for a network. SOLUTION: In the case of receiving a notice of a request of a band from the user, the request is registered in a reservation wait management table. When there is no other user awaiting reservation and a sufficient band, the communication at the requested band is permitted. On the other band, when there is no sufficient band, communication with a band of a node with a minimum band is permitted among nodes on a channel. In the case of receiving release of the band from the user, a deficient band is assigned and when the requested band is assigned, the requested band is deleted from the reservation wait management table, and when there is a user awaiting the reservation, the request band of the user awaiting the reservation is read from the reservation wait management table and the similar processing to above is conducted.
