PROBLEM TO BE SOLVED: To shorten a search time of management terminals when a communication terminal chooses the management terminals which have to be connected, and to suppress using of a medium required for search. SOLUTION: The management terminals 1a and 1b transmit a beacon frame including information required for the communication terminal 2 to connect with themselves every predetermined beacon interval, and transmit a notification frame of existence which shows existence of themselves at least one. The communication terminal 2 chooses the management terminals 1a and 1b to be connected based on the beacon frame and/or the notification frame of the existence which were received.
