Communication by short distance wireless communication (hereinafter referred to as "short range communication"). In the short-range communication, the reach of the radio wave is relatively short, and radio waves may or may not be received depending on the distance between the terminals. Therefore, if the other terminal can receive the radio wave transmitted from one terminal, it is known that both terminals are within the reach of the radio wave.

  Guide terminal 20 and user terminal 30 are information processing devices, such as a smart phone and a tablet type terminal, for example.

  The guide terminal 20 causes the user terminal 30 to perform communication for confirmation of presence by narrow area communication using wide area communication. As a result, since the user terminal 30 can perform short-range communication only when necessary, it is possible to prevent the battery of the user terminal 30 from being wasted.

  The user terminal 30 notifies the guide terminal 20 of the presence or absence of reception of radio waves of the short range communication from the other user terminals 30 using the wide area communication.

Next, with reference to FIG. 4, application (application) distribution processing of the information processing system 1 according to the embodiment will be described. FIG. 4 is a sequence diagram showing an example of application distribution processing of the information processing system 1 according to the embodiment.

  In step S51, the control unit 33 of the user terminal 30 transmits an application request to the server device 10, for example, when detecting that the current position is a predetermined place by GPS (Global Positioning System). Here, the application request may include, for example, information such as the current position of the user terminal 30. Alternatively, an ID of an application for which the user terminal 30 requests distribution may be included.

  Subsequently, the distribution unit 12 of the server device 10 transmits the predetermined application stored in the predetermined application DB 111 to the user terminal 30 (step S52).

  Subsequently, when the user terminal 30 receives an activation operation of the application received from the server device 10 from the user, the user terminal 30 activates the application (step S53).

  Subsequently, the control unit 33 of the user terminal 30 receives an input of a tour ID (tour ID), a name of a user of the user terminal 30, and the like on the screen of the activated application (step S54). The tour ID may be notified to the user by, for example, a travel company or a guide by verbal or E-mail.

  Subsequently, the control unit 33 of the user terminal 30 transmits a request for existence confirmation information to the server device 10 by the application (step S55). Here, the request for the presence confirmation information includes the information on the tour ID described above.

  Subsequently, the control unit 13 of the server device 10 refers to the tour management DB 112 and extracts data associated with the tour ID included in the received request for presence confirmation information (step S56).

  The tour ID is an ID of a tour such as sightseeing by one or more guides and one or more users. The user ID is an ID of a user participating in the tour. The name is the name of the user. The name is set based on, for example, documents when the user applies for a tour to a tour company. The guide flag is information for identifying whether it is a guide or a user (such as a customer) who participates in a tour. For the guide flag, for example, “0” is set for the user, and “1” is set for the guide.

  The short range communication ID is an ID of the user terminal 30 transmitted by the short range wireless communication, and is, for example, a universally unique identifier (UUID) of BLE.

  The wide area communication ID is an ID of a tour guide or user used when performing wide area communication, and is, for example, an ID of a tour guide or user account for performing communication of a message for requesting presence confirmation. .

  Subsequently, the control unit 13 of the server device 10 transmits the extracted data to the user terminal 30 (step S57).

  Subsequently, the control unit 33 of the user terminal 30 stores the received data for presence confirmation in the user DB 311.

  Also in the guide terminal 20, a guide application may be installed by the same process as the process of FIG. 4 described above, and data for existence confirmation may be stored in the user DB 211.

«Confirmation of existence»
Next, the presence confirmation process of the information processing system 1 according to the first embodiment will be described with reference to FIG. FIG. 7 is a sequence diagram showing an example of presence confirmation processing of the information processing system 1 according to the first embodiment. In FIG. 7, solid arrows indicate wide area communication, and broken arrows indicate narrow area communication.

  The instruction unit 23 of the guide terminal 20 transmits a request for response to the user terminal 30-1 using wide area communication via the server device 10 (step S1).

  Subsequently, the notification unit 32 of the user terminal 30-1 transmits a response by the short range communication for a predetermined period (for example, 5 seconds) (step S2). Here, the response includes the ID of the user terminal 30-1 as the transmission source or the ID of the user of the user terminal 30-1 as the transmission source. The notification unit 32 of the user terminal 30-1 may transmit a response by the short range communication at a predetermined cycle.

  Subsequently, the confirmation unit 22 of the guide terminal 20 receives the response from the user terminal 30-1 by the short range communication, and confirms the presence of the user terminal 30-1 (step S3).

  Subsequently, the instruction unit 23 of the guide terminal 20 transmits a request for response to the user terminal 30-2 using the wide area communication via the server device 10 (step S4).

  Subsequently, the notification unit 32 of the user terminal 30-2 transmits a response by the short range communication for a predetermined period (step S5).

  Subsequently, the confirmation unit 22 of the guide terminal 20 receives the response from the user terminal 30-2 by the short range communication, and confirms the presence of the user terminal 30-2 (step S6).

  Thereafter, in the same manner, the guide terminal 20 sequentially confirms the presence of each user terminal 30 that is the target of the presence confirmation.

«Modified example 1 of existence confirmation»
Instead of the instruction unit 23 of the guide terminal 20 sequentially transmitting a request for response to each user terminal 30, the instruction unit 23 of the guide terminal 20 simultaneously transmits a request for response to each user terminal 30, and the user terminal 30 Responses may be sent sequentially. In this case, for example, each user terminal 30 synchronizes time using a wide area communication network. When each user terminal 30 receives a request for a response from the guide terminal 20, the user terminal 30 continues to transmit narrow-area radio waves in the time slot assigned to each user terminal 30. This can prevent radio wave interference. When the time slot length is 5 seconds, the user terminals 30 of 12 users per minute respond by the short range communication.

«Modified example 2 of existence confirmation»
Instead of sequentially transmitting a request for response to each user terminal 30, the instruction unit 23 of the guide terminal 20 may sequentially transmit a request for response to each user terminal 30. In this case, when the server device 10 transmits a response request specifying a tour ID from the guide terminal 20, the server device 10 sequentially transmits a response request to the user terminal 30 of each user associated with the tour ID in the tour management DB 112.

«Confirmation of presence (in the case of short range communication failure)»
Next, with reference to FIG. 8, processing in the case where short-range communication between the guide terminal 20 and the user terminal 30 fails in the information processing system 1 according to the first embodiment will be described. FIG. 8 is a sequence diagram showing an example of processing when the short-range communication of the information processing system 1 according to the first embodiment fails. In FIG. 8, solid arrows indicate wide area communication, and broken arrows indicate narrow area communication.

  In step S11, the instruction unit 23 of the guide terminal 20 transmits a request for response to the user terminal 30-2 using wide area communication via the server device 10.

  Subsequently, the notification unit 32 of the user terminal 30-2 transmits a response by the short range communication for a certain period (step S12).

  Below, the example in case the guide terminal 20 does not receive the response by the short-distance communication from the user terminal 30-2 is demonstrated.

  Subsequently, since the instruction unit 23 of the guide terminal 20 did not receive the response from the user terminal 30-2 by the short range communication within the predetermined time, the user terminal 30-using the wide area communication via the server device 10 A terminal search request is transmitted to the user terminals 30-1, 30-3, ... other than 2 (step S13). Here, the instruction unit 23 of the guide terminal 20 transmits a terminal search request including the tour ID and the user ID, and the server device 10 receives the user among the users associated with the tour ID in the tour management DB 112. A terminal search request is transmitted to the user terminals 30 of users other than the user relating to the user ID. Alternatively, among the users associated with the tour ID in the user DB 211, the instruction unit 23 of the guide terminal 20 sets the broad area communication ID, etc. of each user other than the user of the user terminal 30-2, which is a search target, as a destination It is also possible to designate and transmit a terminal search request via the server device 10.

  Subsequently, when the terminal search request is received, the control unit 33 of the user terminal 30-1, 30-3,... Transitions to the standby state in which the short range communication can be received (step S14). Here, the control unit 33 of the user terminals 30-1, 30-3,... Activates, for example, a reception function such as BLE by the short range communication unit 34. Note that each user terminal 30 may stop the reception function of the short range communication unit 34 and release the standby state after a predetermined time has elapsed.

  Subsequently, the instruction unit 23 of the guide terminal 20 transmits a request for response to the user terminal 30-2 using the wide area communication via the server device 10 (step S15). The request for the response in step S15 may be transmitted by the server device 10 that has received the terminal search request including the user ID of the search target in step S13 instead of the guide terminal 20 transmitting.

  Subsequently, the notification unit 32 of the user terminal 30-2 transmits a response by the short range communication for a certain period (step S16).

  Subsequently, the short range communication unit 34 of at least one of the user terminals 30-1 to 30-3 of the user terminals 30-1, 30-3,... Receives a response by the short range communication from the user terminal 30-2 (step S17). ).

  Subsequently, the notification unit 32 of the user terminal 30 having received the response from the user terminal 30-2 by the short range communication transmits a response reception notification to the guide terminal 20 using the wide area communication via the server device 10. (Step S18). Here, the response reception notification includes the wide area communication ID or the user ID of the user terminal 30-2 that is the transmission source of the response received in step S17.

  Subsequently, the reconfirmation unit 25 of the guide terminal 20 receives the response reception notification by the wide area communication from the user terminal 30, and determines the presence of the user of the user terminal 30-2 (step S19).

«Guide terminal processing»
Next, with reference to FIG. 9, the presence confirmation process in the confirmation unit 22 of the guide terminal 20, the reconfirmation unit 25, and the like will be described. FIG. 9 is a flowchart illustrating an example of the presence confirmation process in the guide terminal 20.

  In step S101, the confirmation unit 22 of the guide terminal 20 sets the presence state of each user stored in the user DB 211 to "absent", for example, when performing the presence confirmation process of FIG. 7 at predetermined intervals (reset). Do.

  FIG. 10 is a view showing an example of data stored in the user DB 211 of the guide terminal 20. As shown in FIG. The user DB 211 stores a name, a guide flag, a short range communication ID, a wide area communication ID, an existing state, and a near user ID in association with the user ID.

  The data of the user ID, the name, the guide flag, the short range communication ID, and the wide area communication ID stored in the user DB 211 is one of the data stored in the tour management DB 112 shown in FIG. It is data associated with the tour ID.

  The confirmation unit 22 of the guide terminal 20 collates the short range communication ID received by the short range communication with the short range communication ID stored in the user DB 211, thereby the user terminal 30 of the transmission source of the short range communication. Identify In addition, the reconfirmation unit 25 of the guide terminal 20 collates the wide area communication ID received by the wide area communication with the wide area communication ID stored in the user DB 211 to obtain the user terminal 30 of the transmission source of the wide area communication. Identify.

  The existence state is information indicating whether the user is present without being out of the guide. The nearby user ID is an ID of another user present in a range in which short range communication with the user terminal 30 of the user is possible.

  Subsequently, the confirmation unit 22 of the guide terminal 20 performs the existence confirmation process of FIG. 7 on the user terminal 30 of each user stored in the user DB 211 (step S102). Here, as shown in step S3 and step S6 of FIG. 7, the user who has been confirmed to be within the predetermined range from the guide by receiving the response by the short range communication has the existence state Set to ".

  Subsequently, the reconfirmation unit 25 of the guide terminal 20 determines that the user whose presence state is "absent" among the users stored in the user DB 211 and who is not selected (that is, the process after step S104 is still performed It is determined whether or not there is a user (not shown) (step S103).

  When the existence state is “absent” and there is an unselected user (YES in step S103), the reconfirmation unit 25 of the guide terminal 20 selects the user as a processing target (step S104). Hereinafter, the selected user is referred to as a “processing target user”.

  Subsequently, the instruction unit 23 of the guide terminal 20 uses the wide area communication ID associated with each user other than the processing target user to request a terminal search request via the server device 10 to the user terminal 30 of each user. (Step S105). Thus, a terminal search request is transmitted to the user terminals 30 of all users other than the processing target user among the users participating in the tour, and the user terminals 30 of all the users are the user terminals of the processing target user It is in a state of waiting for a response from the short range communication from 30.

  Subsequently, as in step S15 described above, the instruction unit 23 of the guide terminal 20 uses the wide area communication ID associated with the processing target user to process a request for response via the server device 10 It transmits to the user terminal 30 of a user (step S106).

  Subsequently, the reconfirmation unit 25 of the guide terminal 20 determines whether a response including the short range communication ID associated with the user to be processed is received by the short range communication within a predetermined time (step S107).

  When a response including the short range communication ID associated with the user to be processed is received by the short range communication within a predetermined time (YES in step S107), the reconfirmation unit 25 of the guide terminal 20 uses the user DB 211. The presence state associated with the user to be processed is set to "present" (step S108), and the process proceeds to step S103.

  If the response including the short range communication ID associated with the user to be processed is not received by the short range communication within a predetermined time (NO in step S107), the reconfirmation unit 25 of the guide terminal 20 performs the process It is determined whether or not the response reception notification including the short range communication ID associated with the target user has been received by the wide area communication within a predetermined time (step S109).

  If the response reception notification including the short range communication ID associated with the processing target user is not received within the predetermined time (NO in step S109), the process proceeds to step S103.

  When the one or more response reception notifications including the short range communication ID associated with the processing target user are received within the predetermined time (YES in step S109), the reconfirmation unit 25 of the guide terminal 20 determines the one or more It is determined whether or not at least one of the existence states associated with each user of the transmission source of the response reception notification is "presence" (step S110).

  If at least one of the existence states associated with each user of the transmission source is "presence" (YES in step S110), the reconfirmation unit 25 of the guide terminal 20 detects the existence associated with the processing target user The state and the presence state associated with each user included in the nearby users associated with the processing target user are set to “present” (step S111), and the process proceeds to step S103. Thereby, for example, the user terminal 30-3 and the user terminal 30-2 can perform short range communication, and the user terminal 30-2 and the user terminal 30-1 can perform short range communication. It is assumed that it is a case where short range communication is possible between -1 and the guide terminal 20. In this case, even if the user terminal 30-3 and the user terminal 30-2 can not perform short range communication with the guide terminal 20, the existence state of each user of the user terminal 30-3 and the user terminal 30-2 Since it is "present", it is determined not to be separated.

  Also, for example, the user terminal 30-3 and the user terminal 30-2 can perform short range communication, and the user terminal 30-3 and the user terminal 30-2 have a short range with the guide terminal 20 or the guide terminal 20. It is assumed that short-range communication with another user terminal 30-1 capable of communication is not possible. In this case, as in the present embodiment, even if the broad area communication is used for the response reception notification, the presence state of each user of the user terminal 30-3 and the user terminal 30-2 remains “absent”, so It can be determined that the user gathers and deviates from the guide.

  When at least one of the existence states associated with each user of the transmission source is not “present” (NO in step S110), the reconfirmation unit 25 of the guide terminal 20 determines the proximity user associated with the processing target user Then, each user of the transmission source is stored (step S112), and the process proceeds to step S103.

  On the other hand, when the existence state is “absent” and there is no unselected user (NO in step S103), the reconfirmation unit 25 of the guide terminal 20 exists among the users stored in the user DB 211. It is determined whether there is one or more users whose status is "absent" (step S113).

  If there is no one or more users whose presence state is "absent" (NO in step S113), the process ends.

  When one or more users whose presence state is “absent” exist (YES in step S113), the reconfirmation unit 25 of the guide terminal 20 displays a message indicating that the one or more users are out of focus on the screen. (Step S114) A predetermined notification is transmitted to the user terminal 30 of the one or more users by using the wide area communication (step S115), and the process is ended. Here, the predetermined notification includes a message prompting to join the guide, current position information of the guide, transmission of a call, and the like.

  The contents described in the first embodiment described above can be applied to any of the embodiments described later.

Second Embodiment
In the first embodiment, an example in which the terminal search request is transmitted to the user terminals 30 of all the users other than the search target user among the users participating in the tour has been described. In the second embodiment, an example will be described in which a terminal search request is transmitted only to the user terminal 30 of each user estimated to be in the vicinity of the search target user. In the second embodiment, since the terminal search request is not transmitted to the user terminal 30 of each user who is not estimated to be in the vicinity of the search target user, the user terminal 30 does not have to wait for reception of the short range communication. . Thereby, the battery consumption of the said user terminal 30 can be prevented. The second embodiment is the same as the first embodiment except for a part of the second embodiment, so the description will be appropriately omitted.

<Functional configuration>
Next, the functional configuration of the information processing system 1 according to the second embodiment will be described with reference to FIG. FIG. 11 is a diagram illustrating an example of a functional configuration of the information processing system 1 according to the second embodiment.

  The storage unit 11 of the server device 10 according to the second embodiment further stores the group DB 113. In the group DB 113, each user terminal 30 is classified into a plurality of groups based on a predetermined standard. Details of data stored in the group DB 113 will be described later. The data stored in the group DB 113 may be set in advance based on, for example, application documents for the tour.

<Processing>
«Group management»
Next, group management processing of the information processing system 1 according to the second embodiment will be described with reference to FIG. FIG. 12 is a sequence diagram showing an example of a group management process of the information processing system 1 according to the second embodiment. Hereinafter, an example of managing a group based on the received radio wave strength will be described.

  In step S201, for example, the user terminal 30-2 periodically transmits the short-range communication ID of the user terminal 30-2 by short-range communication.

  Subsequently, when the user terminal 30-1 receives the short range communication, the short range wireless strength including the received radio wave strength of the short range communication, the received short range communication ID, and the wide area communication ID of the user terminal 30-1. The notification is transmitted to the server device 10 by wide area communication (step S202).

  Subsequently, the user terminal 30-1 transmits the short range communication ID of the user terminal 30-1 by the short range communication (step S203).

  Subsequently, when the user terminal 30-2 receives the short range communication, the short range wireless strength including the received radio wave strength of the short range communication, the received short range communication ID, and the wide area communication ID of the user terminal 30-2. The notification is transmitted to the server device 10 by wide area communication (step S202).

  Subsequently, the server device 10 determines the group of each user based on the short range radio strength notification received from each user terminal 30 (step S205). Here, for example, when the received radio wave strength included in the short range radio strength notification is equal to or more than a predetermined threshold, the server device 10 uses the user terminal 30 user corresponding to the short range communication ID included in the short range radio strength notification. And the user of the user terminal 30 corresponding to the wide area communication ID included in the short range radio strength notification are determined to be included in the same group, and stored in the group DB 113.

  Thereby, for example, the distance between the user terminal 30-1 and the user terminal 30-2 is relatively close, and the received radio field strength of the narrow area communication in at least one side is equal to or higher than the predetermined threshold value. It is assumed that the received radio wave strength of the short range communication in at least one of the user terminal 30 and the second user terminal 30-3 is equal to or greater than a predetermined threshold. In this case, the user terminal 30-1, the user terminal 30-2, and the user terminal 30-2, even if the reception radio field strength of the mutual narrow area communication in both the user terminal 30-1 and the user terminal 30-3 is not equal to or greater than a predetermined threshold. And it is determined that the user of the user terminal 30-3 belongs to the same group.

  FIG. 13 is a diagram showing an example of data stored in the group DB 113. As shown in FIG. The group DB is stored in the group DB 113 in association with the tour ID and the user ID. The group ID is an ID of a group of users. The group ID is not stored for the guide.

  The group ID may be managed by the tour management DB 112 shown in FIG. 5, instead of managing the group ID by the group DB 113.

«Confirmation of presence (in the case of short range communication failure)»
Next, with reference to FIG. 14, processing in the case where short-range communication between the guide terminal 20 and the user terminal 30 fails in the information processing system 1 according to the second embodiment will be described. FIG. 14 is a sequence diagram showing an example of processing when the short distance communication of the information processing system 1 according to the second embodiment fails. In FIG. 14, the solid line arrows indicate wide area communication, and the broken line arrows indicate narrow area communication.

  The processes of steps S301 to S302 are the same as the processes of steps S11 to S12 of the first embodiment shown in FIG.

  In step S303, the instruction unit 23 of the guide terminal 20 does not receive the response from the user terminal 30-2 by the short range communication within the predetermined time, so the wide area communication is used to request the server device 10 to search for a terminal. Send. Here, the terminal search request includes the tour ID and the user ID of the user terminal 30-2.

  In step S304, the control unit 13 of the server device 10 refers to the group DB 113, and transmits a terminal search request to the user terminals 30 of other users belonging to the same group as the search target user. Here, the control unit 13 of the server device 10 acquires, in the group DB 113, the tour ID and the group ID associated with the user ID included in the terminal search request received from the guide terminal 20. Then, the server device 10 extracts each user ID associated with the tour ID and the group ID. Then, the server device 10 transmits a terminal search request from the tour management DB 112 shown in FIG. 5 using the wide area communication ID associated with each user ID.

  The processes of steps S305 to S310 are the same as the processes of steps S14 to S19 of the first embodiment shown in FIG.

  According to the second embodiment, the number of user terminals 30 in the standby state for short range communication is relatively small, and accordingly, the number of user terminals 30 transmitting the response reception notification to the server device 10 is also relatively small. Thereby, the battery consumption of the user terminal 30 can be reduced, and an increase in communication traffic can be prevented.

  In addition, after the terminal search request is transmitted only to the user terminal 30 of each user belonging to the same group by the processing of step S303 to step S306 in FIG. 14 and the response request is transmitted to the user terminal 30 of the search target user When not receiving a response reception notification of a search target user within time, the following processing may be performed. In this case, the server device 10 or the guide terminal 20 transmits a terminal search request to the user terminal 30 of each user participating in the same tour by the processing of step S13 to step S15 of FIG. Sends a response request to the user terminal 30 of In this way, even if the user to be searched for is separated from each user of the same group, etc., it is determined that the user does not deviate from the guide if it is not separated from other users participating in the same tour. Be done.

Third Embodiment
In the first embodiment and the second embodiment, an example has been described in which the guide terminal 20 transmits a response request to the user terminal 30 via wide area communication and receives a response from the user terminal 30 via narrow area communication. In the third embodiment, an example will be described in which the guide terminal 20 transmits a response request to the user terminal 30 by short range communication and receives a wide area communication response from the user terminal 30. Thereby, the same effects as those of the first embodiment and the second embodiment can be realized. Note that the third embodiment is the same as the first embodiment or the second embodiment except for a part thereof, and therefore the description will be appropriately omitted.

<Processing>
«Confirmation of presence (in the case of short range communication failure)»
Next, with reference to FIG. 15, processing in the case where the short-range communication between the guide terminal 20 and the user terminal 30 fails in the information processing system 1 according to the third embodiment will be described. FIG. 15 is a sequence diagram showing an example of processing when the narrow area communication of the information processing system 1 according to the third embodiment fails. In FIG. 15, solid arrows indicate wide area communication, and broken arrows indicate narrow area communication.

  In step S401, the instruction unit 23 of the guide terminal 20 transmits a reception request to the user terminal 30-2 using the wide area communication via the server device 10.

  Subsequently, when the control unit 33 of the user terminal 30-2 receives the reception request, the control unit 33 changes the short range communication unit 34 to the standby state in which the short range communication can be received (step S402).

  Subsequently, the reconfirmation unit 25 of the guide terminal 20 transmits a response request by narrow area communication for a certain period (step S403).

  Below, the example in case the user terminal 30-2 does not receive the response by the short-distance communication from the guide terminal 20 is demonstrated. When the user terminal 30-2 receives a response from the guide terminal 20 by the short range communication, the user terminal 30-2 transmits the response by the wide area communication to the guide terminal 20, thereby confirming the presence Ru.

  Subsequently, since the instruction unit 23 of the guide terminal 20 did not receive the response from the user terminal 30-2 in the wide area communication within the predetermined time, the user terminal 30-2 uses the wide area communication via the server device 10. A terminal search request is transmitted to the other user terminals 30-1, 30-3, ... (step S404). Here, the guide terminal 20 transmits a terminal search request including the tour ID and the user ID, and the server device 10 relates to the received user ID among the users associated with the tour ID in the tour management DB 112. A terminal search request is transmitted to the user terminals 30 of users other than the user. Alternatively, the guide terminal 20 specifies, as a destination, the wide area communication ID or the like of each user other than the user of the user terminal 30-2 as a search target among the users associated with the tour ID in the user DB 211. The terminal search request may be transmitted via the device 10.

  Subsequently, when the terminal search request is received, the control unit 33 of the user terminal 30-1, 30-3,... Causes the short range communication unit 34 to transition to the relay state where the short range communication can be relayed ( Step S405). Here, the user terminals 30-1, 30-3,... Activate a reception function such as BLE, for example.

  Subsequently, the instruction unit 23 of the guide terminal 20 transmits a request for response to the user terminal 30-2 using wide area communication via the server device 10 (step S406).

  Subsequently, when the control unit 33 of the user terminal 30-2 receives the reception request, the control unit 33 of the user terminal 30-2 transitions again to the standby state in which the short-range communication can be received (step S407).

  Subsequently, the reconfirmation unit 25 of the guide terminal 20 transmits a response request by narrow area communication for a certain period (step S408).

  Subsequently, the short range communication unit 34 of at least one of the user terminals 30 among the user terminals 30-1, 30-3,... Receives a response request by the short range communication from the guide terminal 20 (step S409) .

  Subsequently, the short range communication unit 34 of the user terminal 30 that receives the response request by the short range communication from the guide terminal 20 relays (repeats) the response request (step S410).

  Subsequently, when the notification unit 32 of the user terminal 30-2 receives the response request by the short range communication, the notification unit 32 transmits the response to the guide terminal 20 using the wide area communication via the server device 10 (step S411).

  Thereby, in the guide terminal 20, the presence of the user terminal 30-2 is confirmed.

<< Modification of Third Embodiment >>
In the third embodiment, in steps S408 to S410, the guide terminal 20 transmits a response request by short range communication, and instead of transmitting the response request to the user terminals 30-1, 30-3,. , May be processed as follows.

  The instruction unit 23 of the guide terminal 20 instructs the user terminals 30-1, 30-3,... To transmit a response request by wide area communication. Subsequently, the short range communication unit 34 of the user terminal 30-1, 30-3,... Transmits a response request by the short range communication. Then, as in step S411, when the notification unit 32 of the user terminal 30-2 receives the response request by the short range communication, the notification unit 32 of the user terminal 30-2 transmits the response to the guide terminal 20 using the wide area communication via the server device 10. .

  Although the embodiments of the present invention have been described above in detail, the present invention is not limited to such specific embodiments, and various modifications may be made within the scope of the present invention as set forth in the claims.・ Change is possible.
