  When the notification method is “push”, the information providing unit 53 reads the notification information corresponding to the terminal ID of the wireless terminal 5 that can access the site from the notification information table, and the read notification information passes through the wireless LAN access point 3. To the wireless terminal 5.

  FIG. 8 is a diagram illustrating an example of notification information displayed on the display unit of the wireless terminal 5. When the notification method is “page”, for example, as shown in FIG. 8A, when the user of the wireless terminal 5 requests the web server 6 to transmit the price comparison site page 70a, the price comparison site page 70a. The notification information 71a is inserted and displayed on the display unit of the wireless terminal 5.

  When the notification method is “push”, for example, as shown in FIG. 8B, notification information 71 b is displayed on the standby screen 70 b displayed on the display unit at the time of standby in the wireless terminal 5. When the notification method is “push” and the user of the wireless terminal 5 displays the price comparison site page of the web server 6 on the display unit, for example, on the price comparison site page as shown in FIG. 1A. Notification information is displayed in a superimposed manner.

  The notification information 71a and 71b shown in FIG. 8 is an example, and is not limited to such display contents. For example, the information providing unit 53 may be information including the date and time of the participation type event, the map of the location, and the content as the notification information, and in addition to information such as moving images and animations, audio information and vibration It may be information that notifies the wireless terminal 5 of the participation type event by information or the like. Note that the vibration information is, for example, information for operating the vibration unit included in the wireless terminal 5.

  The “participation number condition” is a condition as to whether or not notification information is notified to the wireless terminal 5. For example, if the event information table is in the state shown in FIG. 4 and the notification information table is in the state shown in FIG. 7, the participation of the participating wireless terminal 5 with respect to the participation capacity of the participation type event corresponding to the event ID “G1”. If the number is 40 (= 50 × 80%) or less, it is determined that the “participation number condition” is satisfied.

  The “stay condition” is a stay condition in the communication area 8 of the wireless LAN access point 3 of the wireless terminal 5 that notifies the notification information, and the information providing unit 53 satisfies the “participation number condition” and the “stay condition”. In addition, notification information is notified to the wireless terminal 5.

  For example, assume that the event information table is in the state shown in FIG. 4 and the notification information table is in the state shown in FIG. Further, it is assumed that the number of participating wireless terminals 5 with respect to the participation capacity of the participation type event corresponding to the event ID “G1” is 40 (= 50 × 80%) or less. The “stay condition” corresponding to the participation type event corresponding to the event ID “G1” is “the intensity level is 4 or less and the stay time is 1 minute or more”. In the communication area 8 of the wireless LAN access point 3 with the AP-ID “A1”, the information providing unit 53 has an event ID “ Notification information is notified to the wireless terminals 5 not participating in the participation type event corresponding to “G1”.

  The digital signage 2 is arranged in the vicinity of the wireless LAN access point 3, and the radio wave intensity of the wireless terminal 5 increases as it is closer to the digital signage 2, while the intensity level increases as it is farther from the digital signage 2. Becomes lower. In the notification information table shown in FIG. 7, “stay condition” is set so as to notify the notification information to the wireless terminal 5 located far from the digital signage 2. For example, the strength level of the radio wave intensity is high. The “stay condition” can be set so that the notification information is transmitted to the wireless terminal 5.

(Calculation unit 54)
The calculation unit 54 calculates a display fee for advertising content on the digital signage 2 in accordance with the participation state of the wireless terminal 5 in the participation type event. For example, “number of participants × participation time × standard unit price” is set as the “advertisement fee” as in the advertisement information table shown in FIG. For example, when the number of participants is 50, the average participation time is 30 minutes, and the reference unit price is 5 yen / minute, the calculation unit 54 calculates 7500 yen (= 50 × 30 × 5) as the advertising fee. The

  The participation number is the number of wireless terminals 5 participating in the participation type event. Further, the advertisement information table shown in FIG. 5 is an example. For example, the advertisement fee may be calculated only by “number of participants × reference unit price”, or other calculation methods may be used.

(Privilege grant part 55)
The privilege granting unit 55 transmits the privilege information to the wireless terminal 5 that has participated in the participation type event after notifying the notification information. The privilege information is information on a privilege provided by an advertiser who provides advertisement content to the digital signage 2 and is set in the advertisement information table. The privilege granting unit 55 acquires privilege information corresponding to the event ID of the participation type event in which the wireless terminal 5 participates after notifying the notification information from the advertisement information table, and transmits the privilege information to the wireless terminal 5 via the wireless LAN access point 3. .

  For example, assume that the event information table is in the state shown in FIG. 4, the advertisement information table is in the state shown in FIG. 5, and the AP information table is in the state shown in FIG. The privilege information corresponding to the event ID “G1” is “coupon information C1”. The information providing unit 53 sets the “notification state” to “0” among the wireless terminals 5 having the terminal IDs corresponding to the AP-ID “A1”, and changes the “participation state” from “0” to “1”. The “coupon information C1” is transmitted to the wireless terminal 5 having the terminal ID to be changed to the wireless LAN 5 via the wireless LAN access point 3 with the AP-ID “A1”.

[5. Processing flow of information providing system 1]
Next, a procedure of information providing processing by the information providing system 1 according to the embodiment will be described. 9 to 12 are diagrams for explaining the information provision processing flow by the information provision system 1. In the following, the process of the wireless LAN access point 3 will be described with reference to FIG. 9, and the process of the information providing apparatus 4 will be described with reference to FIGS.

(Processing of wireless LAN access point 3)
First, information processing of the wireless LAN access point 3 according to the embodiment will be described with reference to FIG. FIG. 9 is a flowchart of information processing in the wireless LAN access point 3. Such an operation is a process repeatedly executed by the control unit 23 of the wireless LAN access point 3.

  As shown in FIG. 9, the control unit 23 of the wireless LAN access point 3 determines whether or not the wireless terminal 5 has been detected (step S20). In this process, when it is determined that the wireless terminal 5 has been detected (step S20; Yes), the terminal information is transmitted to the information providing apparatus 4 via the WAN communication unit 22 (step S21).

  When it is determined in step S20 that the wireless terminal 5 has not been detected (step S20; No), or when the process in step S21 is completed, the control unit 23 is connected to the communication network 7 on the WAN side. It is determined whether information is received from the apparatus via the WAN communication unit 22 (step S22). If it is determined that information has been received from the WAN side device (step S22; Yes), the control unit 23 transfers the received information to the LAN side device that is the destination of this information (step S23). The LAN side device is the digital signage 2 or the wireless terminal 5.

  If it is determined in step S22 that information has not been received (step S22; No), or if the processing in step S23 is completed, the control unit 23 determines whether there is a request from the LAN side device to the WAN side device. Is determined (step S24). If it is determined that there is a request from the LAN side device to the WAN side device (step S24; Yes), the control unit 23 transfers the request from the LAN side device to the WAN side device to the WAN side device via the WAN communication unit 22. (Step S25).

  When the process of step S25 is completed, or when it is determined in step S24 that there is no request from the LAN side apparatus to the WAN side apparatus (step S24; No), the control unit 23 ends the process. For example, the control unit 23 can execute the processes of steps S20 and S21, the processes of steps S22 and S23, and the processes of steps S24 and S25 by multitask processing.

(Processing of information providing apparatus 4)
Next, processing of the information providing apparatus 4 will be described. FIG. 10 is a flowchart of information processing in the information providing apparatus 4. Such an operation is a process repeatedly executed by the control unit 32 of the information providing apparatus 4.

  As illustrated in FIG. 10, the control unit 32 determines whether or not detection information transmitted from the wireless LAN access point 3 is received via the communication unit 30 (step S30). When terminal information is received (step S30; Yes), the control part 32 performs a notification process based on the received terminal information (step S31). This notification process is a process of steps S40 to S42 shown in FIG. 11, and will be described in detail later.

  In step S30, when terminal information is not received (step S30; No), or when the process of step S31 ends, the control unit 32 has received an event participation request from the wireless terminal 5 via the communication unit 30. It is determined whether or not (step S32). When the event participation request is received (step S32; Yes), the control unit 32 executes an event participation process (step S33). Such event participation processing is processing in steps S50 to S52 shown in FIG. 12, and will be described in detail later.

  In step S32, when the event participation request is not received (step S32; No), or when the process of step S33 is completed, the control unit 32 determines whether there is an event process (step S34).

  When there is an event process (step S34; Yes), the control unit 32 executes the event process (step S35). The event process is a process related to a participatory event, for example, a process of transmitting event content to the wireless LAN access point 3 or the wireless terminal 5 or a process according to operation information transmitted from the wireless terminal 5.

  When there is no event processing (step S34; No), or when the processing of step S35 ends, the control unit 32 determines whether or not the participation type event ends (step S36). In this process, the control unit 32 determines whether or not the event has ended based on the date and time information specified in the event information table.

  If it determines with the participation type event having been complete | finished (step S36; Yes), the control part 32 will perform an advertisement fee calculation process (step S37). In this processing, the control unit 32 calculates an advertising fee for advertising content to the digital signage 2 according to, for example, the participation state of the wireless terminal 5 in the participation type event.

  When the process of step S37 ends, or when the participation type event has not ended in step S36 (step S36; No), the control unit 32 ends the process.

  Next, the notification process shown in step S31 shown in FIG. 10 will be described. FIG. 11 is a flowchart of notification processing in the information providing apparatus 4.

  As shown in FIG. 11, in the notification process, the control unit 32 determines whether or not the notification condition is satisfied based on information set in the notification information table (step S40). Specifically, the control unit 32 determines that the state of the participation event corresponding to the wireless LAN access point 3 that transmitted the terminal information satisfies the participation number condition, and the wireless terminal 5 corresponding to the terminal information satisfies the stay condition. It is determined that the notification condition is satisfied.

  When the notification information table is in the state illustrated in FIG. 7, for example, the control unit 32 indicates that the number of wireless terminals 5 participating in the participation type event with the event ID “G1” is 80% or less, and “the strength level is It is determined whether or not there is a wireless terminal 5 having a duration of 4 or less and a stay time of 1 minute or longer.

  If it determines with notifying conditions being satisfied in step S40 (step S40; Yes), the control part 32 will be the radio | wireless terminal 5 (henceforth an unnotified terminal) which has not transmitted notification information among the radio | wireless terminals 5 which satisfy a stay condition. Is described) (step S41). In the AP information table, when there is a wireless terminal 5 with a wireless ID whose “notification state” and “participation state” are set to “0” among the wireless terminals 5 satisfying the stay condition, the control unit 32 It is determined that a notification terminal exists.

  If it is determined that there is an unnotified terminal (step S41; Yes), the control unit 32 acquires the notification information from the notification information table and transmits the notification information to the wireless terminal 5 that is an unreported terminal via the wireless LAN access point 3. (Step S42). The control unit 32 transmits the notification information to the wireless terminal 5 based on the “notification method” set in the notification information table, for example, by the “page” or “push” notification method.

  When the process of step S42 is completed, when the notification condition is not satisfied in step S40 (step S40; No), or when it is determined in step S41 that there is no unreported terminal (step S41; Yes), control The unit 32 ends the process.

  Next, the event participation process shown in step S33 shown in FIG. 10 will be described. FIG. 12 is a flowchart of the event participation process in the information providing apparatus 4.

  As shown in FIG. 12, in the event participation process, the control unit 32 determines whether or not the wireless terminal 5 that has made the event participation request is participation after notification notification (step S50). Specifically, in the AP information table, when the “notification state” corresponding to the terminal ID of the wireless terminal 5 that has requested the event participation is “1”, the control unit 32 is participation after notification notification. Is determined.

  When it is determined that the wireless terminal 5 that has made the event participation request is participation after the notification notification (step S50; Yes), the control unit 32 digitally transmits the notification information to the wireless terminal 5 that has participated in the participation event after the notification information is notified. The privilege information from the advertiser who provides the advertising content to the signage 2 is transmitted (step S51).

  In Step S50, when it is determined that the wireless terminal 5 that has requested the event participation is not participation after the notification notification (Step S50; No), and when the process of Step S51 is completed, the control unit 32 determines whether the event participation is Settings are made (step S52), and the process ends. In this processing, the control unit 32 performs event participation setting by changing the “participation state” in the AP information table from “0” to “1”.

[6. (Modification)
In the above-described embodiment, the control unit 32 of the information providing apparatus 4 performs event processing for a participatory event, but an event processing apparatus that performs event processing for a participatory event may be provided separately.

  In this case, the wireless LAN access point 3 analyzes the destination of the communication packet transmitted from the wireless terminal 5 and determines that the wireless terminal 5 is participating in the participation type event when the destination is an event processing device. Then, terminal information including information to that effect is transmitted to the information providing apparatus 4. The detection unit 52 of the information providing device 4 updates the AP information table based on the terminal information transmitted from the wireless LAN access point 3, and determines the participation state of the wireless terminal 5 in the participation type event based on the AP information table. To detect.

  Thereby, for example, even when an event processing device that performs event processing of a participatory event is separated from the information providing device 4, the wireless terminal 5 for participating events can be acquired without acquiring information from the event processing device. It is possible to properly grasp the participation status of. Note that the control unit 32 of the information providing apparatus 4 can also acquire the terminal ID of the wireless terminal 5 participating in the participation type event from the event processing apparatus and set it in the AP information table.

  In the embodiment described above, in the notification information table (see FIG. 7), one “notification method”, “participation number condition”, and “stay condition” are assigned to each event ID. Multiple pieces of information may be assigned. For example, the time period is divided into a plurality of times in relation to the holding time of the participation type event, and “notification method”, “participation number condition”, and “stay condition” can be assigned for each time period. For example, during the period before the start of the event, the notification method is “page”, the participation number condition is “60% or less”, the stay condition is “no condition”, and after the event starts, the notification method is “push”, and the participation number condition Can be set to "80% or less", and the stay condition can be "strength level is 4 or less, stay time is 1 minute or more".

  The control unit 32 can also change the notification condition in relation to the number of wireless terminals 5 that can detect terminal information. For example, when the number of wireless terminals 5 that can detect terminal information is equal to or greater than a predetermined threshold, the control unit 32 determines that there are many wireless terminals 5 in the AP communication area 8. 80% or less ", and the stay condition is" strength level is 4 or less, stay time is 1 minute or more ". On the other hand, when the number of the wireless terminals 5 that can detect the terminal information is less than the predetermined threshold, the control unit 32 determines that the number of the wireless terminals 5 present in the AP communication area 8 is small. % ”And the stay condition is“ strength level is 2 or less, stay time is 20 seconds or more ”. Thus, notification information can be appropriately notified by changing the notification condition according to the number of wireless terminals 5 present in the AP communication area 8. The control unit 32 may limit the wireless terminal 5 capable of detecting terminal information to the wireless terminal 5 in the notifying state, and may include the wireless terminal 5 that is not in the notification state and the wireless terminal 5 in the notification state. .

  In the above embodiment, the transmission route of the notification information is described as being performed via the wireless LAN access point 3. However, if the wireless terminal 5 is, for example, a mobile phone with a wireless LAN function, Notification information can also be transmitted to the wireless terminal 5 via a base station (WAN base station).

  In the above-described embodiment, an example in which a plurality of digital signage 2 and a plurality of wireless LAN access points 3 are associated with one information providing apparatus 4 has been described. Signage 2 and one wireless LAN access point 3 may be associated with each other. In this case, the information providing apparatus 4 and the wireless LAN access point 3 may be configured integrally.

  Further, in the above-described embodiment, the wireless terminal 5 in the communication state has been described as the wireless terminal 5 that can access the site via the wireless LAN access point 3, but the control unit 32 sets the wireless LAN access point 3 as the wireless terminal 5. Only the wireless terminal 5 that is actually accessing the site via the Internet can be targeted for notification.

  In this case, for example, the wireless LAN access point 3 analyzes the destination of the communication packet transmitted from the wireless terminal 5 and transmits the information on the destination to the information providing apparatus 4 as access information. Based on the access information acquired from the wireless LAN access point 3, the information providing device 4 identifies the wireless terminal 5 that is actually accessing the site, and transmits notification information to the identified wireless terminal 5.

  In addition, when the wireless terminal 5 has a GPS function and the latitude / longitude information of the wireless terminal 5 can be acquired, the latitude / longitude information of the wireless terminal 5 can be used as the notification condition of the notification information. For example, in the AP communication area 8, a place having a predetermined positional relationship from the installation location of the digital signage 2 or a predetermined place is set as the notification target area, and the control unit 32 is based on the latitude / longitude information of the wireless terminal 5. Notification information can be transmitted to the wireless terminals 5 existing in the area.

  The control unit 32 can also change the content of the notification information according to the type of the wireless terminal 5 (for example, the size of the display unit or the model of the wireless terminal 5). By doing in this way, appropriate notice information according to the kind of wireless terminal 5 can be transmitted.

In the information providing apparatus 4 of the information providing system 1 according to the embodiment, the event information DB (an example of a storage unit) holds a participation type event performed in conjunction with the wireless terminal 5 and the digital signage 2, Notification information for notifying the installation position is stored, and the detection unit 52 (an example of a terminal detection unit) accesses the site via the wireless LAN access point 3 having the AP communication area 8 including the installation position of the digital signage 2. A possible wireless terminal 5 is detected based on information transmitted from the wireless LAN access point 3, and the information providing unit 53 (an example of a notification unit) detects by the detecting unit 52 when a participation type event is held. Notification information is notified to the wireless terminal 5 via the wireless LAN access point 3.

  With this configuration, the user of the wireless terminal 5 can be actively guided to the installation position of the digital signage 2 where the participation type event is performed. For example, when advertising content is displayed on the digital signage 2, Many users of the wireless terminals 5 can be recognized.

  Further, the information providing unit 53 notifies the notification information via the wireless LAN access point 3 to the wireless terminals 5 that have not participated in the participation type event according to the participation state of the wireless terminal 5 in the participation type event.

  With this configuration, for example, notification information is notified when the number of participating wireless terminals 5 is small, and notification information is not notified when the number of participating wireless terminals 5 has reached the participation capacity. Notification information can be appropriately notified.

  In addition, the calculation unit 54 (an example of a calculation unit) calculates a display fee for advertising content to the digital signage 2 in accordance with the participation state of the wireless terminal 5 in the participation type event.

  With such a configuration, it is possible to set an appropriate advertising fee for displaying the advertising content on the digital signage 2.

  Further, the privilege granting unit 55 (an example of privilege transmission means) transmits the privilege information from the advertiser who provides the advertising content to the digital signage 2 to the wireless terminal 5 that has participated in the participation type event after notifying the notification information. .

  With this configuration, since the privilege information is transmitted to the wireless terminal 5 that has participated in the participation type event after notification information is notified, participation in the participation type event can be actively promoted.

  In addition, the detection unit 52 (an example of a participation state detection unit) detects the participation state of the wireless terminal 5 in the participation type event based on information transmitted from the wireless LAN access point 3.

  With this configuration, for example, even when an event processing device that performs event processing of a participatory event is separated from the information providing device 4, a wireless terminal that participates in a participation type event without acquiring information from the event processing device 5 participation status can be properly grasped.

  In addition, the detection unit 52 (an example of a terminal state detection unit) detects the stay time and / or radio wave intensity of the wireless terminal 5 at the wireless LAN access point 3, and the information providing unit 53 detects the stay detected by the detection unit 52. Notification information is notified via the wireless LAN access point 3 to the wireless terminal 5 whose time and / or radio wave intensity satisfies a predetermined condition.

  With this configuration, the notification information is not transmitted to all the wireless terminals 5 existing in the communication area 8 of the wireless LAN access point 3, the processing load on the information providing device 4 can be reduced, and an appropriate wireless communication can be performed. Notification information can be transmitted to the terminal 5.
