A short-range wireless communication access device controls a first network interface to send broadcast radio data packets for allowing a portable terminal to discover the short-range wireless communication access device in a specified first time range, on the basis of time synchronized with the portable terminal to access a short-range wireless communication network. Further, the short-range wireless communication access device receives operation scenario information for controlling whether to send the broadcast radio data packets through a second network interface, and controls the first network interface to cyclically send the broadcast radio data packets in accordance with a repetition cycle in the first time range based on the repetition cycle included in the operation scenario information, the specified first time range in the repetition cycle, and the time determined from the radio signal received through the second network interface.
