Abstract

When a terminal device initiates a wireless communication when it has not established a wireless link between itself and another wireless device, it transmits, as a management frames in active scanning, a plurality of activation probe requests having frame lengths representing an identifier of a wireless base station to which connection is being made and which is intended to transition from sleep mode to operating mode. Then, the wireless base station receives the plurality of activation probe requests transmitted by the terminal device as management frames in active scanning in a wireless LAN, and, when a plurality of dummy network identifiers detected based on the received plurality of activation probe requests represent the identifier of its own, transitions from sleep mode to operating mode.
