The memory control unit 533 acquires the positioning information "latitude N35.8834, longitude 137.8973" and the positioning accuracy information from the positioning information acquisition unit 536. When the acquired positioning accuracy information is equal to or higher than the reference level, the memory control unit 533 sets the positioning information "latitude N35.8834, longitude 137.8973" and the radio wave condition information "1a = -95 (dBm), 1b = -100 (. dBm), 1c = −120 (dBm) ”is stored in the storage unit 52 in association with each other.

On the other hand, the storage control unit 533 does not store the positioning information in the storage unit 52 when the positioning accuracy information in the reception time information is less than the reference level. In the example shown in FIG. 8, the storage unit 52 has the radio wave state information “1a = −95 (dBm), 1b = −90 (dBm), 1c = −100 (dBm)” and the facility position “latitude N35.6815,” Although it is stored in association with "latitude 139.3424", the positioning result is not stored because the positioning accuracy is less than the reference level. As a result, the positioning result associated with the radio wave condition information "1a = -95 (dBm), 1b = -90 (dBm), 1c = -100 (dBm)" is blank.

The storage control unit 533 may store the positioning information and the radio wave state information in the storage unit 52 in association with each other when the payment information acquisition unit 532 cannot acquire the facility information in the reception time information. When the location of the facility cannot be specified based on the facility information acquired by the payment information acquisition unit 532, the storage control unit 533 may store the positioning information and the radio wave condition information in the storage unit 52 in association with each other. For the data corresponding to the radio wave condition information "1a = -100 (dBm), 1b = -60 (dBm), 1c = -80 (dBm)" in the example shown in FIG. 8, the payment information acquisition unit 532 acquires the facility information. This indicates that the positioning information acquisition unit 536 was able to acquire the positioning information. By operating the memory control unit 533 in this way, even if the payment information acquisition unit 532 cannot acquire the facility information, the location information DB is updated using highly accurate positioning information, so that the location information DB The number of positions registered in can be increased.

By the way, when the communication terminal 2 is in a building having a plurality of floors, the information management device 5 cannot specify which floor of the building the communication terminal 2 is on based on the positioning information, even if the accuracy of the positioning information is high. Therefore, when the position indicated by the positioning information indicates the position of a building on a plurality of floors, the data transmission unit 537 transmits data for confirming the place of stay in the reception time information to the communication terminal 2. May be good. When the communication terminal 2 receives the confirmation request data, for example, it displays "Please enter the floor number of the building that was at 3:00 pm on February 1st" and accepts the input of the floor number from the user of the communication terminal 2.

The communication terminal 2 transmits the input floor number to the information management device 5. In the information management device 5, when the data receiving unit 538 receives the floor number from the communication terminal 2, the storage control unit 533 stores the latitude, longitude and floor number or height in association with the radio wave intensity indicated by the radio wave state information. Store in 52.

By operating the information management device 5 and the communication terminal 2 in this way, the information management device 5 can perform position information on the position in the building even if the position specified based on the positioning information is the position of the building on a plurality of floors. It can be registered in the DB.

As described above, when the payment information acquisition unit 532 can acquire the facility information, the information management device 5 can register the location of the facility indicated by the acquired facility information in the location information DB. On the other hand, when the payment information acquisition unit 532 cannot acquire the facility information or the location of the facility cannot be specified, the information management device 5 registers the position indicated by the positioning information acquired by the positioning information acquisition unit 536 in the location information DB. be able to. Therefore, the information management device 5 can provide position information of more positions.

[Second modification]
In the above description, the case where the payment server 4 acquires the payment time information from the POS terminal 3 is illustrated, but the payment server 4 may acquire the payment time information from the communication terminal 2, and the payment server 4 may acquire the payment time information. The time when the payment process is performed may be acquired from the payment server 4 itself. Further, the communication terminal 2 may transmit the facility information acquired from the POS terminal 3 and the payment time information possessed by the communication terminal 2 to the payment server 4.

[Third variant]
In the above description, the case where the information management device 5 receives the radio wave condition information via at least one of the plurality of wireless communication base stations 1 has been illustrated, but the route through which the information management device 5 receives the radio wave condition information has been illustrated. Is not limited to this. The information management device 5 may receive radio wave condition information from the communication terminal 2 via a wireless network such as Wi-Fi (registered trademark).

[Effect of Information Management Device 5 According to This Embodiment]
As described above, in the information management device 5, the radio wave condition information receiving unit 531 that receives the radio wave condition information from the communication terminal 2, the payment information acquisition unit 532 that receives the location information of the facility where the communication terminal 2 has performed the payment processing, and the like. Has. Then, when the difference between the time indicated by the reception time information and the settlement time indicated by the settlement time information is within a predetermined range, the storage control unit 533 stores the radio wave state information and the location of the facility indicated by the facility information in association with each other. The position information DB is created by storing it in the unit 52.

Therefore, in the position information providing system S, the strength of the radio waves received by the communication terminal 2 from the plurality of wireless communication base stations 1 or the communication between the plurality of wireless communication base stations 1 is performed without using the GPS positioning information having low accuracy. It is possible to construct a position information DB in which a highly accurate position is associated with the strength of the radio wave received from the terminal 2. As a result, when it is necessary to specify the position of the communication terminal 2, the accuracy of specifying the position of the communication terminal 2 is improved by using this position information DB.
