In step S102, the transmission / reception unit 11 of the smart device 10A transmits the calibration request information 41 requesting the start of calibration of the received signal sensitivity to the information processing device 50. Specifically, when the reception unit 12 accepts the selection of the "send" icon on the menu screen 400 shown in FIG. 11A, the transmission / reception unit 11 transmits the calibration request information 41 to the information processing device 50. .. The calibration request information 41 includes the terminal information 801 of the smart device 10A. Then, the terminal transmission / reception unit 51 of the information processing apparatus 50 receives the calibration request information 41.

In step S103, the terminal transmission / reception unit 51 of the information processing apparatus 50 transmits the response request information 43 to the smart device 10A. Similarly, in step S104, the terminal transmission / reception unit 51 of the information processing apparatus 50 transmits the response request information 43 to the reference device 30.

In step S108, the transmission / reception unit 31 of the reference device 30 transmits the response information 47, which is a response to the response request information 43 transmitted from the information processing apparatus 50, to the information processing apparatus 50. Specifically, the transmission / reception unit 31 generates response information 47 including reference information indicating a value (reference value) of the reception signal strength measured by the reception signal strength measurement unit 32. Then, the transmission / reception unit 31 transmits the generated response information 47 to the information processing device 50.

Thereby, the information processing apparatus 50 can grasp the received signal sensitivity of the smart device 10A by comparing the received signal strength of the smart device 10A with the reference value acquired by the reference device 30. For example, in the information processing apparatus 50, when the reception sensitivity of the smart device 10A is −45 [dBm] and the reception sensitivity (reference value) of the reference device 30 is −40 [dBm], the reception sensitivity of the smart device 10A is −45 [dBm]. It can be recognized that it is 5 [dB] lower than the reference value.

In step S206, the terminal transmission / reception unit 51 of the information processing device 50 transmits the reception sensitivity information 802 received by the server transmission / reception unit 55 to the smart device 10A (an example of the reception sensitivity information transmission means).

In step S207, when the reception sensitivity information 802 is received by the transmission / reception unit 11, the smart device 10A executes a process of specifying the relative distance to and from the information processing device 50. Then, in step S208, the display control unit 13 of the smart device 10A causes the display 506a to display the device identification information of the information processing device 50 determined to be located within a predetermined range.

Is set to "-45 [dBm]". The correction value set by the correction unit 17 may be stored in the threshold value information 200.

In step S304, when the transmission / reception unit 11 of the smart device 10A receives the beacon packet (wireless signal) from the information processing device 50, the process shifts to step S305. The beacon packet (radio signal) delivered from the information processing device 50 includes the device identification information of the information processing device 50. The device identification information includes, for example, a device name, a device ID, an SSID, an ESID, and the like. On the other hand, the transmission / reception unit 11 repeats the process of step S304 until the beacon packet (radio signal) is received. In step S305, the received signal strength measuring unit 15 of the smart device 10A measures the received signal strength of the received beacon packet (radio signal).

In step S306, the determination unit 18 of the smart device 10A is smart for the information processing device 50 based on the value of the received signal strength measured by the received signal strength measuring unit 15 and the correction value set by the correction unit 17. Specify the relative distance of the device 10A (an example of a specific step). Specifically, the determination unit 18 shifts the process to step S307, for example, when the value of the received signal intensity measured by the received signal intensity measuring unit 15 is larger than the correction value set by the correction unit 17. .. On the other hand, in step S306, the determination unit 18 ends the process when, for example, the measured received signal strength value is equal to or less than the correction value set by the correction unit 17.

Specifically, the display control unit 13 displays the search screen 450 as shown in FIG. 11B on the display 106a. The search screen 450 displays the device identification information of the information processing device 50 determined to be located within a predetermined range by the determination unit 18. On the search screen 450 shown in FIG. 11B, for example, the information processing device 50 having the device name "Tokyo office 8F A" and the information processing device 50 having the device name "Tokyo office 8F B" are displayed. To. The user of the smart device 10A can use the selected information processing device 50 by selecting the device identification information displayed on the search screen 450 and selecting the "selection" icon.

● Modification example of the first embodiment ●
Subsequently, the information processing system according to the modified example of the first embodiment will be described. In the information processing system according to the modification of the first embodiment, the cloud server 70 receives the reception sensitivity information 802 of the smart device 10A with the information processing device 50 (reference device 30) provided by different vendors. It is stored in the sensitivity information management table 800B.

FIG. 12 is a diagram showing an example of a reception sensitivity information management table according to a modified example of the first embodiment. The reception sensitivity information management table 800B stores the terminal information 801 of the smart device 10A and the reception sensitivity information 802 in association with the information of the vendor name 803 for identifying the vendor (manufacturer) of the information processing apparatus 50.

In the reception sensitivity information management table 800B shown in FIG. 12, for example, the MAC address “F8: df: a8: 77: 53: 9d” and the model number “MO-01J” for the information processing device 50 provided by “Vendor A”. The reception sensitivity information 802 of the smart device 10A (hereinafter referred to as device 1) is −5 [dB]. Further, the reception sensitivity information 802 of the device 1 with respect to the information processing apparatus 50 provided by the "vendor B" is +2 [dB]. Further, the reception sensitivity information 802 of the device 1 with respect to the information processing apparatus 50 provided by "Vendor C" is +1 [dB].

As described above, the reception sensitivity information 802 may differ even if it is the same smart device 10A, depending on the vendor (manufacturer) that provides the information processing apparatus 50. This is because the reference device 30 used for correcting the reception sensitivity is different for each vendor, and therefore the reception signal strength as a reference for calculating the reception sensitivity information 802 is different.

Therefore, the information processing system 1B according to the first embodiment does not need to provide the cloud server 70 or the reception sensitivity information management table 800A according to the vendor of the information processing apparatus 50 set in the user environment, and therefore from different vendors.

The threshold value update unit 20 is a function of setting or updating the threshold value information 200 stored in the storage unit 100. The threshold value update unit 20 updates the reception signal strength of the beacon packet (radio signal) received by the transmission / reception unit 11 as the threshold value information 200, for example. The threshold value update unit 20 is realized by, for example, a program executed by the CPU 101 shown in FIG.

FIG. 14 is a flowchart showing an example of the threshold information update process in the smart device according to the second embodiment. Since the processing of steps S401 to S405 is the same as the processing of steps S301 to S305 shown in FIG. 10, the description thereof will be omitted.

In step S406, when the smart device 10B sets the value of the received signal strength measured by the received signal strength measuring unit 15 as a threshold value, the smart device 10B shifts the process to step S407. Specifically, the display control unit 13 of the smart device 10B causes the display 106a to display a selection screen for allowing the user to select whether or not to update the threshold information 200 when the received signal strength is measured. Then, when the reception unit 12 of the smart device 10B receives the user input to update the threshold information 200 on the selection screen, the process shifts to step S407.

In step S407, the threshold value updating unit 20 of the smart device 10B updates the threshold value information 200 stored in the storage unit 100. Specifically, the threshold value updating unit 20 sets the value of the received signal intensity measured by the received signal intensity measuring unit 15 to the signal intensity included in the threshold information 200.

● Effects of the Second Embodiment As described above, the information processing system 1C according to the second embodiment has a threshold value of the positional relationship (distance from the information processing apparatus 50) at which the information processing apparatus 50 can be used. The threshold information 200 can be set to a desired value according to the environment in which the user uses the system. Since the information processing system 1C can easily change the threshold value information 200 by using the received signal strength of the beacon packet (radio signal) received by the smart device 10B, for example, information in the user environment by changing the layout or the like. This is effective when the arrangement of the processing device 50 is changed.

● Summary ●
As described above, the information processing system according to the embodiment of the present invention includes an information processing device 50 that executes predetermined processing and a smart device 10A (an example of a communication terminal) that requests processing by the information processing device 50. , Is an information processing system 1A. Then, the information processing device 50 corrects the measurement information indicating the received signal strength of the smart device 10A with respect to the radio signal transmitted from the information processing device 50 (an example of a specific transmission source) and the received signal strength of the smart device 10A. Receiving indicating the difference between the received signal strengths of the smart device 10A and the reference device 30 calculated based on the reference information indicating the received signal strength with respect to the radio signal transmitted from the information processing apparatus 50 in the reference device 30 for the purpose. The sensitivity information 802 is transmitted to the smart device 10A. Further, the smart device 10A corrects the threshold information 200 used for comparing the relative distance of the smart device 10A with respect to the information processing device 50 based on the reception sensitivity information 802 transmitted from the information processing device 50, and corrects the threshold value. The relative distance of the smart device 10A to the information processing apparatus 50 is specified by using the information 200 and the measurement information. Therefore, the information processing system 1A can improve the accuracy of specifying the relative distance of the smart device 10A to the information processing device 50 regardless of the measurement environment.

Further, in the information processing system according to the embodiment of the present invention, the information processing device 50 uses the search request information 61 (an example of a search request) for requesting a search for the information processing device 50, and the smart device 10A (an example of a communication terminal). ), And the reception sensitivity information 802 is transmitted to the smart device 10A, which is the source of the search request information 61. Therefore, the information processing system 1A can specify the relative distance of the smart device 10A to the information processing device 50 using the corrected reception sensitivity of the smart device 10A in response to the search request from the smart device 10A. ..

Further, in the information processing system according to the embodiment of the present invention, the information processing apparatus 50 receives the calibration request information 41 requesting the calibration of the received signal strength of the smart device 10A (an example of a communication terminal) from the smart device 10A. If so, the response request information 43 requesting a response from the smart device 10A and the reference device 30 is transmitted to the smart device 10A and the reference device 30. Further, the smart device 10A transmits the response information 45 (an example of the first response information) including the measurement information indicating the received signal strength of the received response request information 43 to the information processing apparatus 50. Then, the reference device 30 transmits the response information 47 (an example of the second response information) including the reference information indicating the received signal strength of the received response request information 43 to the information processing apparatus 50.

Therefore, since the information processing system 1A only needs to respond to the response request from the information processing apparatus 50 after transmitting the calibration request, the smart device 10A actively transfers the information necessary for correction to the information processing apparatus 50. The reception sensitivity of the smart device 10A can be corrected without transmission. Further, the information processing system 1A can correct the reception sensitivity of the smart device 10A without performing synchronization processing between the smart device 10A and the reference device 30.

Then, in the information processing system 1A, the information processing device 50 transmits the calculated reception sensitivity information 802 to the cloud server 70, and the cloud server 70 stores the reception sensitivity information 802 transmitted from the information processing device 50. Therefore, the information processing system 1A can use the reception sensitivity information 802 stored in the cloud server 70 as long as it can be connected to the communication network 5. Therefore, in any environment, the information processing system 1A is smart for the information processing device 50. The measurement accuracy of the relative distance of the device 10A can be improved.

Further, in the information processing system according to the embodiment of the present invention, the cloud server 70 (an example of a server device) stores the identification information for identifying the smart device 10A (an example of a communication terminal) and the reception sensitivity information 802 in association with each other.
