Embodiment 1

[0044] Fig. 4 is the structural diagram of the wireless communication system of embodiment 1 of the present invention, in the figure, 11 is portable information terminal namely portable telephone set, 12~14 is the fixed terminal (access point) such as automatic vending machine, 15 is service provision The vendor's access point management device manages a fixed terminal that is allowed to establish a Bluetooth connection and sends the device address BD_ADDR of the fixed terminal.

[0045] 21 is an address storage part (storage device) that receives and stores the device address BD_ADDR sent from the access point management device 15; 22 is an address checking part (checking device). 14 inherent device address, then check the device address BD_ADDR stored in the address storage part 21 and the inherent device address received by the short-range wireless data communication part 23; 23 is the short-range wireless data communication part (sending device, receiving device, connection...

Embodiment 2

[0060] In the above-mentioned first embodiment, the case where only one device address in the address checking section 22 matches is described, but in the case of a plurality of devices having the same address, the number of fixed terminals for confirming the presence or absence of the service may also be limited. Thus, even in this case, wireless communication with a desired fixed terminal can be performed more quickly than in the conventional embodiment.

Embodiment 3

[0062] Although not particularly mentioned in the first embodiment above, the device address BD_ADDR stored in the address storage unit 21 may be appropriately updated by the access point management device 15 .

[0063] Thus, the address storage section 21 can store the latest device address BD_ADDR.
