The license unit 34 corresponds to an example of “terminal information acquisition unit”, “license generation unit”, “state detection unit”, “first condition change unit”, and “second condition change unit”. The license revocation unit 35 corresponds to an example of “license revocation means”.

(About the receiver)
The receiving unit 31 receives requests and information transmitted from the wireless LAN access point 2 and the wireless terminal 5 via the WAN communication unit 21. For example, the receiving unit 31 receives terminal information from the wireless LAN access point 2, and also receives a content page transmission request, a content usage request, a content usage confirmation request, and a content extension confirmation from the wireless terminal 5 via the wireless LAN access point 2. Receive requests and so on.

  When receiving the terminal information from the wireless LAN access point 2, the receiving unit 31 sets the received terminal information in the terminal information table of the AP information DB 22. FIG. 6 is a diagram illustrating an example of the terminal information table.

  As illustrated in FIG. 6, one or more “AP-IDs” are associated with each “store ID” in the terminal information table, and “terminal ID” and “check-in time” are associated with each “AP-ID”. ”,“ Check-out time ”,“ radio wave intensity ”,“ additional information ”, and other information associated with each other.

  “Store ID” is identification information of the installation location of the wireless LAN access point 2 and is assigned to each commercial space as the installation location. In such a commercial space, two or more wireless LAN access points 2 can be installed, and different contents can be provided for each AP communication area of the wireless LAN access point 2.

  “AP-ID” is identification information of the wireless LAN access point 2 installed in the store of the corresponding “store ID”. For example, the example illustrated in FIG. 6 indicates that the wireless LAN access point 2 with the AP-IDs “201” and “202” is installed in the store with the store ID “301”.

  “Terminal ID” is the terminal ID of the wireless terminal 5 existing in the AP communication area.

It shows that it exists.

  “Radio wave intensity” is information on the radio wave intensity of the wireless terminal 5 existing in the AP communication area. In the example shown in FIG. 6, for the sake of convenience, the latest information on the radio wave intensity is shown corresponding to each terminal ID, but from the time when the wireless terminal 5 enters the AP communication area (hereinafter referred to as check-in). Is set in the terminal information table. In the example shown in FIG. 6, the unit of the radio wave intensity is represented by “dBm” as in the example shown in FIG. 3, but can be set in other units.

  When receiving the terminal information from the wireless LAN access point 2, the receiving unit 31 sets the terminal ID and the radio wave intensity information included in the terminal information in the terminal information table in association with the “AP-ID” included in the terminal information. To do.

  “Check-in time” is the time when the wireless terminal 5 enters the AP communication area. The staying time of the wireless terminal 5 in the communication area can be detected by comparing the approach time and the current time.

  “Check-out time” is the time when the wireless terminal 5 that has entered the AP communication area subsequently leaves the communication area. In the example shown in FIG. 6, information on the wireless terminal 5 that has left the communication area is not included. However, when the wireless terminal 5 that has entered the communication area has left the communication area, the reception unit 31 causes the withdrawal time to be set. Is set in the terminal information table as the checkout time.

  For example, the reception unit 31 sets the time when a predetermined time has elapsed since the reception of the radio field intensity information of the wireless terminal 5 that has entered the AP communication area as the “checkout time” of the wireless terminal 5.

  Further, the “additional information” set in the terminal information table is information on time extension or upgrade of the content providing service given to the user of the wireless terminal 5. Such “additional information” is information corresponding to the action of the user of the wireless terminal 5 at the installation location of the wireless LAN access point 2. The “additional information” is transmitted via the wireless LAN access point 2 from, for example, a terminal device (hereinafter referred to as a store terminal) connected to the wireless LAN access point 2 in a communicable manner or the wireless terminal 5.

  For example, when the wireless LAN access point 2 is installed in a coffee shop or a restaurant, information including the point information corresponding to the amount of goods purchased by the user of the wireless terminal 5 and the terminal ID of the wireless terminal 5 is added in the installed store. Information is transmitted from the store terminal to the content management device 3.

  For example, when the wireless LAN access point 2 is installed in a hospital, a beauty salon, or the like, point information according to the waiting time of the user of the wireless terminal 5 can be set by the store terminal. In addition, for example, point information corresponding to the frequency of visits to the user of the wireless terminal 5 and the number of visits to the store where the wireless LAN access point 2 is installed can be set by the store terminal. Then, information including the set point information and the terminal ID is transmitted from the store terminal to the content management device 3 as additional information.

  Note that the additional information may be transmitted from the wireless terminal 5 to the content management device 3 instead of being transmitted from the store terminal to the content management device 3. For example, a receipt to which a QR code (registered trademark) including additional information is added is provided to the user of the wireless terminal 5 by the store side device. Then, the user provided with the receipt accesses the content management device 3 based on the QR code (registered trademark) from the wireless terminal 5. Thereby, the additional information is transmitted to the content management apparatus 3.

  The receiving unit 31 adds point information transmitted from the store terminal or the wireless terminal 5 via the wireless LAN access point 2 to “additional information” in the terminal information table. The initial value of “additional information” is “0”, but for example, point information defined in advance for each wireless LAN access point 2 can be added in response to a request from the store terminal.

  The set of “terminal ID”, “check-in time”, “check-out time”, “radio wave intensity”, and “additional information” for which “check-out time” is set is recorded as history information by the terminal information acquisition unit 15. Managed. Based on such history information, the control unit 25 can also grasp information such as the number of check-ins and the check-in frequency of each wireless terminal 5, and can set additional information based on such information.

(About the page generator)
When the reception unit 31 receives a content page transmission request, the page generation unit 32 generates a content page corresponding to the wireless LAN access point 2 that relayed the request. The content page generated by the page generation unit 32 is transmitted to the requesting wireless terminal 5 by the transmission unit 33 and displayed on the display unit of the wireless terminal 5. The content page is information displayed on the wireless terminal 5 in order to select content provided by the content management device 3.

  The content page is generated by the page generation unit 32 based on the content information table and the content setting table stored in the content DB 23. FIG. 7 is a diagram illustrating an example of the content information table.

  As illustrated in FIG. 7, in the content information table, “store name” and one or more “AP-IDs” are associated with each “store ID”, and “available content” is associated with each “AP-ID”. "Is associated with the information. “Available content” is divided into “movie”, “music”, “magazine”, “manga”, and “game” content categories, and usage level information is set for each content category.

  Regarding the usage level set for each content category, “0” indicates that the usage is not possible, and “1” to “3” indicate the usage level. The number of contents that the user can use increases in the order of usage levels “1”, “2”, and “3”.

  For example, for the AP-ID “202” shown in FIG. 7, the content category “music”, “magazine”, “manga”, and “game” are set to be usable, and the content category “movie” is unusable. Is set. In addition, the content categories “music” and “game” are set to a usage level “1”, and the content categories “magazine” and “manga” are set to a usage level “2”.

  The page generation unit 32 is a content page in which selectable content categories are set based on the available content set for the wireless LAN access point 2 that relays the content page transmission request from the wireless terminal 5 (hereinafter referred to as categories). Created as a selection page).

  For example, it is assumed that the content information table is in the state shown in FIG. 7, and the content page transmission request is received by the receiving unit 31 via the wireless LAN access point 2 with the AP-ID “202”. In this case, for example, as shown in FIG. 9A, the page generation unit 32 generates a category selection page in which content categories of “music”, “magazine”, “manga”, and “game” are set. FIG. 9A is a diagram illustrating a display example of the category selection page generated by the page generation unit 32.

  When the user of the wireless terminal 5 selects a desired content category from among the content categories displayed on the category selection page by operating the operation unit, selection information including information on the selected content category is transmitted via the wireless LAN access point 2. Received by the receiving unit 31 of the content management device 3.

  The page generation unit 32 is a content page (hereinafter referred to as a content selection page) that specifies content to be used based on the selection information received by the reception unit 31, the content information table stored in the content DB 23, and the content setting table. ) Is generated.

  Here, the content setting table used for generating the content selection page will be described. FIG. 8 is a diagram illustrating an example of a content setting table. As shown in FIG. 8, in the content setting table, for each “content ID”, information such as “content name”, “content classification”, “content storage position”, and “usage level” is associated. included. “Content ID” is identification information unique to the content, and is assigned to each content.

  “Content name”, “content category”, “content storage location” and “use level” are the content name, category, storage location and use level. For example, a movie, music, magazine, manga, or game is set in the “content category”.

  The page generation unit 32 reads the usage level of the content category specified by the selection information from the wireless terminal 5 received by the reception unit 31 from the content information table, and displays the content name of the content set to the usage level, etc. Read from the setting table. Then, the page generation unit 32 generates a content selection page that displays the read content name.

  For example, assume that the content information table is in the state shown in FIG. 7 and the content setting table is in the state shown in FIG. Further, it is assumed that the selection information of the content category “magazine” is received by the receiving unit 31 via the wireless LAN access point 2 with the AP-ID “202”.

  In this case, the usage level of the “magazine” corresponding to the AP-ID “202” is “2”, and the page generation unit 32 belongs to the content classification “magazine” among the contents set in the content setting table. And, the contents including “2” as the usage level are selected. For example, the content with the content name “50001” having the content name “weekly XX” includes “2” as the usage level, and is therefore selected by the page generation unit 32.

  Then, the page generation unit 32 selects a content including a content name list of the selected content, for example, the content names “weekly XX”, “weekly ☆☆”, and “monthly □□” as shown in FIG. Generate a page. FIG. 9B is a diagram illustrating a display example of the content selection page generated by the page generation unit 32.

  The content selection page is described so that information including a content ID corresponding to the selected content is transmitted to the content management device 3 when the content is selected by the user of the wireless terminal 5. For example, in a state where the content selection page shown in FIG. 9B is displayed on the wireless terminal 5, when the user of the wireless terminal 5 operates the operation unit and selects the content of “Weekly OO”, the content ID A content use request “50001” is transmitted from the wireless terminal 5.

  As described above, the page generation unit 32 generates a category selection page and a content selection page according to the wireless LAN access point 2 to which the content page transmission request and selection information are transferred.

  The usage level set for each content category in the content information table can be changed in various ways, and may be “0” or “1”, or may be five or more levels. Further, instead of setting the usage level for each content category in the content information table, the content ID of each available content can be set. In addition, the content ID can be set together with the usage level.

(About the license part)
The license unit 34 generates content license information corresponding to the content use request from the wireless terminal 5 based on the terminal information table stored in the AP information DB 22 and the license condition table stored in the license condition information DB 24.

  Specifically, when the content use request from the wireless terminal 5 is received by the receiving unit 31, the license unit 34 stores the identification information of the requesting wireless terminal 5 in the terminal information table stored in the AP information DB 22. Determine whether it is set.

  When the reception unit 31 receives a content usage request from the wireless terminal 5 for which identification information is not set in the terminal information table, it is not a content usage request via the specific wireless LAN access point 2, so the license unit 34 Error information is transmitted to the requesting wireless terminal 5.

  On the other hand, when the reception unit 31 receives a content usage request from the wireless terminal 5 for which identification information is set in the terminal information table, the license unit 34 transmits the radio wave of the wireless terminal 5 that has made the content usage request from the terminal information table. Get strength information.

  Then, the license unit 34 determines whether or not the acquired radio wave intensity information is greater than or equal to a predetermined value. If the radio wave intensity information is greater than or equal to the first threshold, the license unit 34 determines that the content usage condition is satisfied, and the content usage request The license information generation process for the content to be processed is started.

  For example, it is assumed that the terminal information table stored in the AP information DB 22 is in the state illustrated in FIG. 6 and the first threshold is “−50 (dBm)”. Then, it is assumed that a content use request is made from the wireless terminal 5 with the terminal ID “10001” and the wireless terminal 5 with the terminal ID “10021” existing in the AP communication area with the AP-ID “201”.

  In this case, the license unit 34 receives the radio field intensity information “−45 (dBm)” of the radio terminal 5 with the terminal ID “10001” and the radio field intensity information “−55 (dBm)” of the radio terminal 5 with the terminal ID “10021”. To get. The radio field intensity information of the wireless terminal 5 with the terminal ID “10001” is equal to or greater than the first threshold value, and the radio field intensity information of the wireless terminal 5 with the terminal ID “10021” is less than the first threshold value.

  Accordingly, the license unit 34 starts processing for generating license information of content that is a target of a content use request made from the wireless terminal 5 with the terminal ID “10001”. On the other hand, the license unit 34 determines not to generate the license information of the content that is the target of the content use request made from the wireless terminal 5 with the terminal ID “10021”.

  When the license information generation process is started, the license unit 34 determines whether or not the license condition in the license condition table stored in the license condition information DB 24 is satisfied. If the license condition is satisfied, the license unit 34 generates license information. FIG. 10 is a diagram illustrating an example of the license condition table.

  As shown in FIG. 10, in the license condition table, one or more “AP-IDs” are associated with each “store ID”, and “license condition” information is associated with each “AP-ID”. Information is included. The “license condition” includes information associated with information such as “type”, “condition 1”, and “condition 2”.

  “Type” is information indicating the type of license condition, and “Condition 1” and “Condition 2” are information indicating the contents of the license condition. In the license condition table shown in FIG. 10, a condition of time (stay time) from when the wireless terminal 5 enters the AP communication area (hereinafter referred to as check-in) is set. Conditions such as the number of contents that can be used by the wireless terminal 5 can also be set.

  When the “type” is set to “1”, the license unit 34 generates license information under the license condition “condition 1”, and when the “type” is set to “2”, the “condition 2” License information is generated with the license condition of "."

  The “type” in the license condition table is set based on a request from a store side device such as a store terminal, for example. For example, the store side device transmits a request to change the “type” in the license condition table to the content management device 3 based on the state of the installation space of the wireless LAN access point 2. The license unit 34 changes the “type” in the license condition table in response to a request from the store side device.

  For example, when the wireless LAN access point 2 is installed in a vehicle and the vehicle stops or is delayed due to an accident or the like, a request for changing the “type” is transmitted from the vehicle-side device. In response to the request, the license unit 34 changes the “type” from “1” to “2”. Thereby, since the use time of content is extended, a user's dissatisfaction can be reduced.

  License conditions include fixed conditions and variable conditions. The fixed condition is a license condition in which a preset time is a content use time. The variation condition is a license condition in which a period corresponding to the state of the installation space of the wireless LAN access point 2 is a content use time.

  Further, the fixed condition may include an addition condition. In this case, for example, a fixed time is set as an initial value, and a time corresponding to point information (additional information) set in the wireless terminal 5 is added. . That is, when the point information set in the wireless terminal 5 is “0”, the initial value is set as the content usage time, and when the point information set in the wireless terminal 5 is “1” or more, The time obtained by multiplying the point information by the addition unit value is added to the initial value and set as the content usage time.

  For example, in the license condition table illustrated in FIG. 10, for example, “1” is set in “Type” corresponding to the AP-ID “201”, and the initial value “1 hour” is set as a fixed condition in “Condition 1”. ", And the addition unit value" 10 minutes "is set. In addition, “2” is set in “Type” corresponding to the AP-ID “204”, and “12 hours” is set as a fixed condition in “Condition 2”.

  The variation condition is, for example, a condition in which a period corresponding to the degree of congestion of the installation space of the wireless LAN access point 2 is used as the content use time. In the example illustrated in FIG. 10, the “condition” corresponding to the AP-ID “203” is used. 1 ”is set. The degree of congestion is calculated based on, for example, the number of wireless terminals 5 present in the AP communication area or the staying time.

  For example, the license unit 34 shortens the content use time when there are many wireless terminals 5 in the AP communication area, and lengthens the content use time when there are few wireless terminals 5. Thereby, for example, when the inside of a store is congested, it is possible to reduce the use time of content and avoid congestion due to content use.

  Further, the license unit 34 shortens the content use time when the average stay time of the wireless terminal 5 existing in the AP communication area is long, and when the average stay time of the wireless terminal 5 is short, Increase usage time. This also avoids congestion due to content usage.

  Note that the content use time may be changed based on the average stay time and the number of wireless terminals 5 existing in the AP communication area. Thereby, the congestion degree in a store can be calculated more accurately.

  In addition, when the AP communication area is, for example, a hospital waiting place or a beauty salon, when the number of wireless terminals 5 existing in the AP communication area is large or when the average stay time is long, the content use time is lengthened. When the number of wireless terminals 5 is small or when the average stay time is short, the content use time is shortened.

  Thereby, even when the waiting time in the installation space of the wireless LAN access point 2 is long, the use time of the content can be increased accordingly, and unpleasantness due to the waiting time can be reduced. it can.

  Note that the license unit 34 can easily detect the number and stay time of the wireless terminals 5 in the AP communication area based on the terminal information table stored in the AP information DB 22. In addition, the variable condition is not limited to the degree of congestion in the AP communication area, and a period according to the other state of the installation space of the wireless LAN access point 2 can be used as the content use time.

  Here, it is assumed that the terminal information table is in the state shown in FIG. 6 and the license condition table is in the state shown in FIG. Then, it is assumed that there is a content use request from the wireless terminal 5 with the terminal ID “10013” via the wireless LAN access point 2 with the AP-ID “201”.

  In this case, since the type corresponding to the AP-ID “201” is “1” in the license condition table, the license unit 34 acquires the license condition of “condition 1”. Further, the license unit 34 reads “check-in time” and “additional information” of the wireless terminal 5 with the terminal ID “10013” from the terminal information table.

  Since the license condition of “condition 1” is the initial value “1 hour” and the addition unit value “10 minutes”, and the “additional information” of the wireless terminal 5 is “3”, the addition unit value “10 minutes”. Is multiplied by additional information “3” and the result is added to the initial value “1 hour”. As a result, the content usage time in the wireless terminal 5 with the terminal ID “10013” is “1 hour 30 minutes”.

  In addition, since the “check-in time” is “4/1 12:21:34”, the license unit 34 adds “content usage time” to “check-in time” to obtain “4/1 13 : 51: 34 "is generated as license information (use time limit).

  However, if the license term has expired, the license unit 34 determines that the license condition is not satisfied, and does not generate license information. That is, the license unit 34 does not generate license information for the wireless terminal 5 when the time since the wireless terminal 5 checked in exceeds the time specified in the license condition.

  When the license information is generated, the license unit 34 extracts the content information that is the target of the content use request from the content DB 23. Then, the content information and license information that are the target of the content use request are transmitted from the transmission unit 33 to the requesting wireless terminal 5.

  The content information includes encrypted content data, and the license information includes condition information and decryption key information. The condition information is information that defines content usage conditions such as a usage time limit, and the decryption key information is information for decrypting encrypted content data.

  The transmission unit 33 transmits the content information and the license information to the wireless terminal 5 at the same time. In this case, the transmission unit 33 can transmit data obtained by combining content information and license information. Further, the content information and the license information can be transmitted to the wireless terminal 5 separately.

  As described above, when the license unit 34 satisfies the license condition set for the wireless LAN access point 2 that relays the content usage request from the wireless terminal 5, the license unit 34 determines the content usage request target based on the license condition. The license information of the content to be generated is generated.

  Upon receiving the content information corresponding to the content use request and the license information, the control unit of the wireless terminal 5 decrypts the encrypted content data included in the content information based on the decryption key included in the license information, and is included in the license information. Playback based on the condition information. The control unit of the wireless terminal 5 is prohibited from using the content when the condition information has reached the usage time limit.

  The control unit of the wireless terminal 5 transmits a content extension confirmation request to the content management apparatus 3 when the license information has expired while the content is being used by the user due to content playback or the like. When the content extension confirmation request is received by the receiving unit 31, the license unit 34 determines whether or not license information can be further issued to the requesting wireless terminal 5. If it is determined that the license information cannot be issued, the license unit 34 transmits error information to the requesting wireless terminal 5.

  On the other hand, when it is determined that license information can be issued, the license unit 34 newly generates license information, and the license information is transmitted to the wireless terminal 5 by the transmission unit 33. As a result, the wireless terminal 5 can continue to reproduce content whose license information has expired due to the expiration of use, and the user of the wireless terminal 5 can continue to use the content.

  For example, after the wireless terminal 5 acquires the license information, when the point information is set in the wireless terminal 5 and the information of the addition unit value is set in the corresponding condition of the license condition table, the license unit 34 New license information is generated in the same procedure as that for generating license information.

  Further, after the wireless terminal 5 obtains the license information, the license unit 34 is licensed on the condition that the user of the wireless terminal 5 pays the price even if the point information is not added to the wireless terminal 5. Information can also be generated. In this case, even if it is not a content extension confirmation request from a specific wireless LAN access point 2, the license unit 34 can also generate license information.

  Further, even when the user of the wireless terminal 5 moves from the store where the wireless LAN access point 2 using the content is installed to the store where the wireless LAN access point 2 is installed, the content classification and the usage level match. Existing content can be continuously used based on a content extension confirmation request or a content transmission request.

(About the license revocation part)
Next, the license revocation unit 35 will be described. The control unit of the wireless terminal 5 transmits a content use confirmation request to the content management apparatus 3 periodically (for example, every 5 minutes) when the content is used by the user by playing back the content or the like.

  When the content management apparatus 3 receives the content usage confirmation request via the wireless LAN access point 2, the content revocation unit 35 determines whether or not the license information is revoked. When the receiving unit 31 receives the content usage confirmation request, the license revocation unit 35 acquires the radio wave intensity information of the wireless terminal 5 that is the request source of the content usage confirmation request from the terminal information table stored in the AP information DB 22.

  Then, the license revocation unit 35 determines whether or not the acquired radio wave intensity information is greater than or equal to the second threshold value. If the radio wave intensity information is greater than or equal to the second threshold value, the license revocation unit 35 is a wireless that is the request source of the content usage confirmation request. A content use confirmation response indicating permission for continuous use is transmitted to the terminal 5. The control unit of the wireless terminal 5 that has received such information continues to reproduce the content and continue using the content by the user.

  On the other hand, when the acquired radio field strength information is less than the second threshold, the license revocation unit 35 sends a content usage confirmation response indicating prohibition of continuous usage to the wireless terminal 5 that is the request source of the content usage confirmation request. Send. The control unit of the wireless terminal 5 that has received such information stops the reproduction of the content and the like, and stops the use of the content by the user.

  Note that the second threshold value may be the same value as the first threshold value, but is preferably smaller than the first threshold value. By doing so, for example, it is possible to reduce the problem that the reproduction of the content is stopped immediately after the reproduction of the content is started, and it is possible to reproduce the content more stably.

  In addition, the license revocation unit 35 only receives a content use confirmation response indicating prohibition of continuous use when it has been less than the second threshold continuously for a predetermined time or when the ratio of being less than the second threshold is not less than the predetermined value. Can also be sent. This also makes it possible to reproduce content more stably. The same applies hereinafter.

[5. Wireless LAN access point processing flow]
Next, information processing of the wireless LAN access point 2 according to the embodiment will be described with reference to FIG. FIG. 11 is a flowchart of information processing in the wireless LAN access point 2 according to the embodiment. Such an operation is a process repeatedly executed by the control unit 14 of the wireless LAN access point 2.

  As shown in FIG. 11, the control unit 14 of the wireless LAN access point 2 executes terminal information storage processing (step S20). In this process, the control unit 14 sets the terminal information included in the wireless signal received from the wireless terminal 5 in the existing terminal data in the storage unit 13.

  Next, the control part 14 determines whether it is a transmission opportunity of terminal information (step S21). If it determines with it being a transmission opportunity of terminal information (step S21; Yes), the control part 14 will read terminal information from the existing terminal data of the memory | storage part 13, and will transmit to the content management apparatus 3 (step S22).

  When the process of step S22 is completed, or when it is determined in step S21 that the transmission of terminal information is not triggered (step S21; No), the control unit 14 determines whether there is an information relay request ( Step S23). For example, when receiving a signal destined for the content management device 3 from the wireless terminal 5 or a signal destined for the wireless terminal 5 from the content management device 3, the control unit 14 determines that there is an information relay request.

  When it is determined that there is an information relay request (step S23; Yes), the control unit 14 performs a relay process (step S24). For example, the control unit 14 transfers a signal destined for the content management device 3 from the wireless terminal 5 to the content management device 3, and transfers a signal destined for the wireless terminal 5 from the content management device 3 to the wireless terminal 5. Note that the control unit 14 includes the AP-ID information in a signal destined for the content management device 3 from the wireless terminal 5 and transfers the signal to the content management device 3. Thereby, the content management apparatus 3 can grasp that the signal is relayed by the wireless LAN access point 2.

  When the process of step S24 is completed, or when it is determined in step S23 that there is no information relay request (step S23; No), the control unit 14 ends the process. For example, the control unit 14 can execute the process of step S20, the processes of steps S21 and S22, and the processes of steps S23 and S24 in parallel.

[6. Processing flow of content management device]
Next, information processing of the content management apparatus 3 according to the embodiment will be described with reference to FIG. FIG. 12 is a flowchart of information processing in the content management apparatus 3 according to the embodiment. Such an operation is a process repeatedly executed by the control unit 25 of the content management apparatus 3.

  As shown in FIG. 12, the control unit 25 of the content management apparatus 3 determines whether or not terminal information has been received from the wireless LAN access point 2 (step S30). When it is determined that the terminal information has been received (step S30; Yes), the control unit 25 sets the terminal information in the AP information DB 22 that has received the terminal information from the wireless LAN access point 2 (step S31).

  When the process of step S31 is completed, or when it is determined in step S30 that terminal information has not been received (step S30; No), the control unit 25 determines whether or not a content page transmission request has been received. (Step S32). If it determines with having received the content page transmission request (step S32; Yes), the control part 25 will perform the production | generation process of a content page (step S33). The content page generation process is executed by the page generation unit 32 as described above. In this process, when it is determined that the transfer source wireless LAN access point of the content page transmission request is not set in the content information table, the control unit 25 transmits error information to the requesting wireless terminal 5.

  When the process of step S33 is completed, or when it is determined in step S32 that a content page transmission request has not been received (step S32; No), the control unit 25 determines whether or not a content use request has been received. Determination is made (step S34). If it determines with having received the content utilization request (step S34; Yes), the control part 25 will perform the production | generation process of the license information of the content corresponding to a content utilization request (step S35). The license information generation process is executed by the license unit 34 as described above. For example, when the content use condition is not satisfied, the control unit 25 transmits error information to the requesting wireless terminal 5.

  When the process of step S35 is completed, or when it is determined in step S34 that a content usage request has not been received (step S34; No), the control unit 25 determines whether a content usage confirmation request has been received. Determination is made (step S36). If it is determined that the content usage confirmation request has been received (step S36; Yes), the control unit 25 performs a revocation process of the license information of the content corresponding to the content usage confirmation request (step S37). The license information revocation process is executed by the license revocation unit 35 as described above.

  When the process of step S37 is completed, or when it is determined in step S36 that a content usage confirmation request has not been received (step S36; No), the control unit 25 determines whether or not a content extension confirmation request has been received. Is determined (step S38). If it is determined that the content extension confirmation request has been received (step S38; Yes), the control unit 25 regenerates the license information of the content corresponding to the content extension confirmation request (step S39). The license information regeneration process is executed by the license unit 34 as described above. For example, when the content use condition is not satisfied, the control unit 25 transmits error information to the requesting wireless terminal 5.

  When the process of step S39 ends, or when the content extension confirmation request is not received in step S38 (step S38; No), the control unit 25 ends the process.

[7. (Modification)
In the above-described embodiment, the control unit 25 of the content management apparatus 3 determines whether or not the radio wave intensity information is greater than or equal to the second threshold. However, the control unit 14 of the wireless LAN access point 2 determines the radio wave intensity. You may determine whether information is more than a 2nd threshold value. In this case, the control unit 14 of the wireless LAN access point 2 transmits the determination result to the content management apparatus 3, and the control unit 25 of the content management apparatus 3 is based on the determination result transmitted from the wireless LAN access point 2. Decide whether to expire the license information.

  In the above-described embodiment, the content use confirmation request is periodically transmitted from the wireless terminal 5 to the content management apparatus 3. However, when the radio wave reception intensity acquired by the wireless terminal 5 is equal to or less than a predetermined value. The wireless terminal 5 may start transmitting a content usage confirmation request. In this way, for example, the power consumption of the wireless terminal 5 can be reduced.

  In the above-described embodiment, the content management device 3 performs the license information revocation process. However, the wireless LAN access point 2 may perform the license information revocation process. In this case, the control unit 14 of the wireless LAN access point 2 performs a license revocation process for the wireless terminal 5 whose radio wave intensity information is less than the second threshold value. Such processing will be specifically described with reference to FIG. FIG. 13 is an explanatory diagram of another content usage management method according to the embodiment.

  As shown in FIG. 13, when receiving the content information and license information transmitted from the content management device 3 (step S40), the control unit of the wireless terminal 5 reproduces the content based on the received content information and license information. Start (step S41). The wireless signal is repeatedly transmitted from the wireless terminal 5 (steps S43 and S45), and the control unit 14 of the wireless LAN access point 2 obtains the radio field intensity information of the wireless terminal 5 from the wireless signal repeatedly transmitted from the wireless terminal 5. Determination is made (steps S44, S46).

  The control unit 14 of the wireless LAN access point 2 transmits license revocation information for requesting revocation of license information to the wireless terminal 5 whose radio field intensity information is less than the second threshold (step S47). The control unit of the wireless terminal 5 that has received the license revocation information stops the reproduction of the content and the like, and stops the use of the content by the user (step S48).

  As described above, when the control unit 14 of the wireless LAN access point 2 performs the license revocation process, it is possible to execute a process faster than the process performed by the content management apparatus 3 via the communication network 4.

  Note that the license expiration process can be performed only by the wireless terminal 5 instead of the license expiration process by the content management device 3 or the wireless LAN access point 2. For example, the control unit of the wireless terminal 5 detects the radio wave reception intensity from the radio signal transmitted from the wireless LAN access point 2, and invalidates the license information when the radio wave reception intensity becomes less than the second threshold. You can also.

  In the above-described embodiment, the same license condition is described for the same wireless LAN access point 2 regardless of the content category. However, the license condition may be set for each content category. it can. In this case, the license conditions for each content category can be changed according to, for example, the degree of congestion at the store.

  In addition, the upper limit number of contents used per wireless terminal 5 can be set in the license condition. The control unit 25 can change the upper limit number of use according to, for example, the number of wireless terminals 5 existing in the communication area of the wireless LAN access point 2. In this case, for example, the control unit 25 decreases the upper limit number of use as the number of wireless terminals 5 existing in the communication area of the wireless LAN access point 2 increases.

  In the above description, the time condition from when the wireless terminal 5 checked in is described as an example of the license condition defined in the license condition table. However, the time condition after receiving the content transmission request is the license condition. It can also be.
