PROBLEM TO BE SOLVED: To allow for management of a device moving to the outside of BLE communication area, by identifying without relying upon the BLE communication, in the wireless LAN communication system which enables use of the wireless LAN communication system only for the device in the BLE communication area, by setting a Bluetooth communication area (BLE communication area) narrower than the wireless LAN communication area, in the wireless LAN communication area.SOLUTION: A first list 91 including the Bluetooth address of a device located in the BLE communication area 6, and the IP address of wireless LAN is provided. The IP address of a device interrupted the BLE communication is searched from the first list 91, and the wireless LAN communication line and BLE communication line corresponding to the IP address thus searched are disconnected. Consequently, a device moved to the outside of the BLE communication area 6 can be identified without relying upon the BLE communication, and disconnection, or the like, of the communication line can be managed.SELECTED DRAWING: Figure 13 |
