Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a communication capacity management device 1 according to an embodiment of the present invention. In the present embodiment, the communication capacity management device 1 manages the communication capacity of a wireless communication line with a limited communication capacity. In FIG. 1, the communication capacity management device 1 includes a communication unit 10, a remaining capacity management unit 12, a remaining capacity management data storage unit 14, and an additional purchase processing unit 16.

  The communication unit 10 communicates with other devices. The remaining capacity management unit 12 manages the remaining capacity (remaining capacity) of the communication capacity for a wireless communication line with a limited communication capacity. There are two types of communication capacities for wireless communication lines: regular grant communication capacity and additional purchase communication capacity. The regularly assigned communication capacity is a communication capacity with a use period granted by a predetermined amount every predetermined period. For example, on the first day of every month, 10 GB (gigabytes) is assigned as the periodical granted communication capacity within the expiration date “within the month in which the periodical granted communication capacity is granted”. The additional purchased communication capacity is an additional purchased communication capacity with an expiration date. As the additional purchase communication capacity, for example, 100 MB (megabytes) as the communication data amount is additionally purchased with the expiration date “31 days from the additional purchase date”. The remaining capacity management unit 12 manages the remaining capacity by distinguishing between the regularly granted communication capacity and the additional purchased communication capacity. The remaining capacity management data storage unit 14 stores remaining capacity management data. The additional purchase processing unit 16 performs processing for additional purchase of additional purchase communication capacity.

  FIG. 2 is a block diagram illustrating a configuration example of hardware for realizing the communication capacity management apparatus 1 illustrated in FIG. In FIG. 1, the communication capacity management device 1 includes a CPU unit 20, a communication unit 10, and a storage unit 22. These units are configured to exchange data. The CPU unit 20 controls the communication capacity management device 1. This control function is realized by the CPU unit 20 executing a computer program. The communication unit 10 communicates with other devices. The storage unit 22 stores a computer program executed by the CPU unit 20 and various data. The storage unit 22 stores a communication capacity management program 24.

  The functions of the remaining capacity management unit 12, the remaining capacity management data storage unit 14 and the additional purchase processing unit 16 shown in FIG. 1 are the communication capacity management program 24 stored in the storage unit 22 by the CPU unit 20 shown in FIG. It is realized by executing. Further, the remaining capacity management data storage unit 14 shown in FIG. 1 is provided in the storage unit 22 shown in FIG.

  FIG. 3 is a diagram illustrating a configuration example of a wireless communication system using the communication capacity management device 1 according to the present embodiment. In FIG. 3, a terminal 102 is connected to a base station 104 through a wireless communication line 106. The wireless communication line 106 has a limited communication capacity. User data transmitted from the terminal 102 to the base station 104 using the wireless communication line 106 is transferred from the base station 104 to the gateway 108. If the communication of the terminal 102 using the wireless communication line 106 is permitted, the gateway 108 outputs the user data of the terminal 102 transferred from the base station 104 to the Internet 110. Similarly, the gateway 108 transfers user data input from the Internet 110 and destined for the terminal 102 to the terminal 102 via the base station 104 if the communication of the terminal 102 using the wireless communication line 106 is permitted. .

  If the communication capacity of the wireless communication line 106 is within the limit, communication of the terminal 102 using the wireless communication line 106 is permitted. On the other hand, when the communication capacity of the wireless communication line 106 is not limited, communication of the terminal 102 using the wireless communication line 106 is not permitted. Or, even if communication is permitted, the communication speed decreases. Thus, the terminal 102 can communicate with other communication devices connected to the Internet 110 using the wireless communication line 106 as long as the communication capacity of the wireless communication line 106 is within the limit. it can. On the other hand, when the communication capacity of the wireless communication line 106 is not limited, the terminal 102 communicates with another communication device connected to the Internet 110 using the wireless communication line 106. I can't. Or, even if communication is possible, the communication speed decreases.

  The communication control device 112 instructs the gateway 108 whether to permit (non-permitted) communication of the terminal 102 that uses the wireless communication line 106 or the communication speed. The communication permission or non-permission or communication speed of the terminal 102 using the wireless communication line 106 is based on the communication permission information of the wireless communication line 106 from the communication capacity management device 1. Further, the communication control apparatus 112 acquires transfer data amount information indicating the transfer amount of user data transferred by the gateway 108 through communication of the terminal 102 using the wireless communication line 106 from the gateway 108. This transfer data amount information is transmitted from the communication control device 112 to the communication capacity management device 1.

  The communication capacity management apparatus 1 updates the remaining capacity of the communication capacity for the wireless communication line 106 based on the transfer data amount information received from the communication control apparatus 112. Further, the communication capacity management device 1 transmits the communication permission information of the wireless communication line 106 to the communication control device 112 based on the remaining communication capacity of the wireless communication line 106. This communication permission information is information on permission or non-permission of communication of the terminal 102 using the wireless communication line 106 and restriction on the communication speed.

  The user contract information management device 114 manages information (user contract information) of users who have contracted with the wireless communication line 106. As the user contract information, there is information indicating a user identifier (user ID), an identification number (line number) of the wireless communication line 106, a contract content for communication capacity, and the like. The communication capacity management apparatus 1 inquires of the user contract information management apparatus 114 about user contract information as necessary.

  The payment device 116 performs payment processing for payment by the user. The communication capacity management device 1 inquires of the payment device 116 about the payment status of the payment by the user, if necessary.

  The terminal 102 can access the communication capacity management device 1 by communication. Communication between the terminal 102 and the communication capacity management apparatus 1 may be communication via the wireless communication line 106 or may be communication not via the wireless communication line 106. The communication capacity management device 1 performs a corresponding process in response to a request from the terminal 102.

  Next, the operation of the communication capacity management device 1 according to this embodiment will be described. In the following description, for convenience of explanation, as an example of the regularly granted communication capacity, it is assumed that 10 GB is assigned as the communication data amount on the first day of each month within the expiration date “within the month in which the regularly granted communication capacity is assigned”. Further, it is assumed that the additional purchase communication capacity is additionally purchased in the unit of 100 MB as the communication data amount with the expiration date “31 days from the additional purchase date”.

[Remaining capacity management]
First, the remaining capacity management method according to the present embodiment will be described. FIG. 4 is a diagram illustrating a configuration example of remaining capacity management data according to the present embodiment. The remaining capacity management data is stored in the remaining capacity management data storage unit 14. In FIG. 4, the remaining capacity management data includes a line number, a user ID, a periodical assigned communication capacity management data, and additional purchased communication capacity management data for each line number. The user ID is an identifier of a user who subscribes to the line number. The periodically assigned communication capacity management data is management data of the remaining amount of the periodically assigned communication capacity. The additional purchase communication capacity management data is management data of the remaining amount of additional purchase communication capacity. The user ID, the line number, and the contract status of the regularly granted communication capacity and the contract status of the additional purchase communication capacity for each line number are acquired from the user contract information management apparatus 114. In addition, the periodical communication capacity is determined by the manufacturer of the terminal 102 associated with the wireless communication line 106 (for example, whether it is a smartphone or a tablet terminal) and the model (for example, the same smartphone). Different predetermined amounts may be given for each predetermined period.

  FIG. 5 is a diagram showing a configuration example (for example, management data A_0001) of the periodically assigned communication capacity management data according to the present embodiment. In FIG. 5, the periodically assigned communication capacity management data includes information indicating the grant month and information indicating the remaining capacity assigned to the grant month for each month in which the regularly grant communication capacity is granted.

  FIG. 6 is a diagram showing a configuration example (for example, management data B_0001) of additional purchase communication capacity management data according to the present embodiment. In FIG. 6, the additional purchase communication capacity management data includes, for each additional purchase, a purchase number for identifying the additional purchase, information indicating the remaining capacity for the additional purchase, and an expiration date for the additional purchase. It has information to show.

  7 and 8 are flowcharts showing the procedure of the remaining capacity management method according to the present embodiment. First, with reference to FIG. 7, operations related to provision of periodically granted communication capacity and additional purchase of additional purchased communication capacity will be described. The process of FIG. 7 is started at a predetermined time (for example, at a constant cycle).

(Step S <b> 11) The remaining capacity management unit 12 determines when the periodical communication capacity is granted. Here, since the time for granting the regularly granted communication capacity is the first day of every month, the remaining capacity management unit 12 determines whether the current date is a day.

(Step S12) As a result of the determination in step S11, if it is a grant timing, the process proceeds to step S13, and if it is not a grant timing, the process proceeds to step S14.

(Step S13) The remaining capacity management unit 12 updates the regularly assigned communication capacity management data. In the update of the regularly assigned communication capacity management data, data with the grant month being the current month and the remaining capacity being a predetermined amount is added to the periodically assigned communication capacity management data of each line number. Here, since the provision amount of the periodic grant communication capacity is 10 GB, data with the grant month of the current month and the remaining capacity of 10 GB is added. Accordingly, for example, on July 1, 2014, data of “July 2014, 10 GB” is added to the periodical assigned communication capacity management data (management data A_0001) illustrated in FIG.

(Step S14) The remaining capacity management unit 12 confirms the additional purchase of the additional purchased communication capacity. In the confirmation of the additional purchase, it is confirmed whether or not the additional purchase processing unit 16 has performed a process of performing a new additional purchase of the additional purchase communication capacity.

(Step S15) As a result of the confirmation in Step S14, if there is a new additional purchase of additional purchase communication capacity, the process proceeds to Step S16, and if there is no new additional purchase of additional purchase communication capacity, the processing of FIG. To do.

(Step S16) The remaining capacity management unit 12 updates the additional purchased communication capacity management data. In the update of the additional purchase communication capacity management data, the new additional purchase purchase number and the remaining capacity are added to the additional purchase communication capacity management data of the line number for which the additional purchase communication capacity has been newly purchased. The data including the information indicating the additional purchase communication capacity for the additional purchase and the information indicating the expiration date of the remaining capacity is added. Thereby, for example, data of “B0001_xx2, 100 MB, July 25, 2014” is added to the additional purchased communication capacity management data (management data B_0001) illustrated in FIG. 6.

  Next, with reference to FIG. 8, operations related to consumption of the regularly granted communication capacity and the additional purchased communication capacity will be described. The process of FIG. 8 is started when a communication permission inquiry is received from the communication control apparatus 112.

(Step S21) The remaining capacity management unit 12 determines the remaining capacity for the line number (inquiry line number) for which the communication control device 112 has inquired about communication permission. This determination is made based on the remaining capacity management data stored in the remaining capacity management data storage unit 14.

(Step S <b> 22) The remaining capacity management unit 12 transmits communication permission information for the inquiry line number to the communication control device 112 based on the determination result of the remaining capacity. For example, if there is a remaining capacity within the expiration date, communication permission information is notified to the communication control device 112 using communication permission information. On the other hand, if there is no remaining capacity within the expiration date, the communication control device 112 is notified of communication non-permission or communication speed limitation by the communication permission information.

(Step S23) Based on the transfer data amount information received from the communication control device 112, the remaining capacity management unit 12 updates the remaining capacity management data of the line number corresponding to the transfer data amount information. In this update, the consumption based on the transfer data amount information is reduced from the remaining capacity within the expiration date indicated by the remaining capacity management data of the line number.

  Next, an example of a method for consuming remaining capacity according to the present embodiment will be described.

[Example 1 of remaining capacity consumption method]
The remaining capacity management unit 12 consumes the regularly granted communication capacity before the additional purchased communication capacity. An example 1 of this remaining capacity consumption method will be described. First, for the line number for which the remaining capacity is consumed (consumed line number), the remaining capacity is specified from the regularly assigned communication capacity management data, and the remaining capacity within the expiration date is specified from the additional purchased communication capacity management data. . As a result of this specific determination, when both the regularly granted communication capacity and the additional purchased communication capacity have a remaining capacity within the expiration date, the remaining capacity within the expiration date of the periodic grant communication capacity is consumed first. If the remaining capacity within the period of use of the regularly granted communication capacity is not sufficient, the shortage is further consumed from the remaining capacity within the period of use of the additional purchased communication capacity. In addition, when there is a remaining capacity within the expiration date only for either the regularly granted communication capacity or the additional purchase communication capacity, the remaining capacity within the expiration date is used.

  According to Example 1 of the remaining capacity consumption method described above, by preferentially consuming the regularly assigned communication capacity, an effect of preventing the periodically assigned communication capacity that is automatically automatically given from being wasted can be obtained.

[Example 2 of remaining capacity consumption method]
Example 2 of the remaining capacity consumption method is a modification of Example 1 of the remaining capacity consumption method described above. In the remaining capacity consumption method example 2 as well, in principle, as in the remaining capacity consumption method example 1 described above, the regularly granted communication capacity is consumed before the additional purchased communication capacity. However, the additional purchased communication capacity whose remaining period until the expiration date is equal to or less than the predetermined period is exceptionally consumed before the regularly assigned communication capacity.

  Example 2 of this remaining capacity consumption method will be described. First, for the line number to be consumed, the remaining capacity within the expiration date is specified from the regularly assigned communication capacity management data, and the remaining capacity within the expiration date is specified from the additional purchased communication capacity management data. If there is a remaining capacity within the expiration date for both the periodically granted communication capacity and the additional purchased communication capacity as a result of this specific determination, the remaining period until the expiration date of the remaining capacity within the expiration date of the additional purchased communication capacity is further calculated. And specified from the additional purchase communication capacity management data. If the remaining period until the expiration date of the remaining capacity within the expiration date of the additional purchased communication capacity is less than or equal to the predetermined period (remaining period determination threshold) as a result of this specific result, the additional purchased communication capacity is within the expiration date The remaining capacity is consumed. If the remaining capacity within the expiration date of the additional purchased communication capacity is not sufficient, the shortage is further consumed from the remaining capacity within the expiration date of the periodical communication capacity. In addition, when only one of the regularly granted communication capacity and the additional purchased communication capacity has a remaining capacity within the expiration date, it is consumed from the remaining capacity within the expiration date. It is.

  According to the second example of the remaining capacity consumption method described above, the remaining purchased capacity that is about to be expired and that is about to expire can be consumed earlier than the regularly assigned communication capacity. Thereby, it can contribute to preventing the situation where the additional purchase communication capacity becomes unusable due to the expiration of the use period.

  Note that the above-described remaining period determination threshold value may be fixedly determined or may be dynamically determined. For example, for a line number that is determined to have a particularly low communication frequency and communication volume, the remaining period determination threshold value may be set longer than the initial value to consume additional purchased communication capacity early. Alternatively, a menu that allows the user to set the remaining period determination threshold may be provided, and the user may set the remaining period determination threshold using the menu.

[Example 3 of remaining capacity consumption method]
The remaining capacity management unit 12 preferentially consumes one of the regularly granted communication capacity and the additionally purchased communication capacity that has a shorter remaining period until the expiration date.

[Example 4 of remaining capacity consumption method]
The remaining capacity management unit 12 determines whether to consume the regularly granted communication capacity or the additional purchased communication capacity according to the user's selection when the remaining period until the expiration date of the additional purchased communication capacity is equal to or shorter than a predetermined period. . For this reason, a menu is provided that allows the user to select which of the regularly granted communication capacity or the additional purchase communication capacity is consumed. Thereby, for example, when the expiration date for past additional purchases is extended by re-additional purchase of communication capacity, a user who plans to purchase additional purchase communication capacity again, User convenience can be achieved, for example, consumption is preferable.

  Next, an example of exceptional processing of additional purchase communication capacity according to the present embodiment will be described. Since the additional purchased communication capacity has an expiration date, the remaining purchased capacity of the additional purchased communication capacity cannot be used in principle. However, since this principle alone can be a wasteful situation for the user, it is convenient for the user by providing an exceptional process for additional purchased communication capacity.

[Example 1 of exceptional processing of additional purchased communication capacity]
The remaining capacity management unit 12 extends the expiration date for the additional purchased communication capacity of the past additional purchase in the remaining capacity for a predetermined period in response to the new additional purchase of the additional purchased communication capacity. Example 1 of the exceptional processing of the additional purchase communication capacity will be described. First, when the additional purchase processing unit 16 performs a process of performing a new additional purchase of additional purchased communication capacity, a past additional purchase is performed from the additional purchased communication capacity management data for the line number where the new additional purchase has been made. Identify the remaining capacity within the expiration date of the minute. As a result of this specific determination, if there is a remaining capacity within the expiration date for the past additional purchase, the additional purchase communication capacity management data is set so as to extend the expiration date of the remaining capacity within the expiration date by a predetermined period. Update.

  FIG. 9 is a conceptual diagram for explaining Example 1 of exceptional processing for additional purchased communication capacity according to the present embodiment. In FIG. 9, 300 MB of the additional purchased communication capacity additionally purchased on the date “t1” remains on the date “t2” which is the expiration date of use. Here, if there is a new additional purchase (500 MB in the example of FIG. 9) by the date “t2” that is within the expiration date of the 300 MB, the expiration date of the 300 MB within the expiration date is extended by “31 days”. The As a result, it is avoided that the 300 MB cannot be used because it has expired on the date “t2” which is the original expiration date. As a result, in the example of FIG. 9, a total of 800 MB including 300 MB revived from the expiration date and 500 MB for the new additional purchase can be used with the expiration date “31 days”.

  According to the example 1 of the exceptional processing of the additional purchased communication capacity described above, it is added by extending the expiration date of the remaining capacity within the expiration date of the additional purchased communication capacity on the condition that the additional purchased communication capacity is newly purchased. This contributes to preventing the situation where the purchased communication capacity becomes unusable due to the expiration of the usage period. Moreover, the effect of prompting the user to newly purchase additional additional communication capacity can be obtained according to the condition of new additional purchase of additional purchased communication capacity.

  In addition, by using Example 1 of the exceptional processing of additional purchased communication capacity in combination with Example 1 of the remaining capacity consumption method described above, a periodical period that is automatically granted periodically by preferentially consuming the periodically granted communication capacity It is possible to prevent the additional purchased communication capacity from being used up by the expiration date because the additional purchased communication capacity is delayed due to the preferential consumption of the regular granted communication capacity while preventing the granted communication capacity from being wasted. The double effect of preventing is obtained.

  In this example, the expiration date of the additional purchased communication capacity is “31 days from the additional purchase date”, but is not limited to this. For example, the expiration date of the additional purchased communication capacity may be a predetermined period from the use start date.

  Also, in this example, the expiration date for past additional purchases is extended by re-additional purchase of communication capacity, but the expiration date for past additional purchases is not extended by re-additional purchase of communication capacity. It may be.

[Example 2 of exceptional processing of additional purchased communication capacity]
The remaining capacity management unit 12 adds the additional purchased communication capacity for the expired usage period to the remaining capacity of the communication capacity under a predetermined restoration condition. In the example 2 of the exceptional processing of the additional purchased communication capacity, the additional purchased communication capacity that cannot be normally used because the expiration date has expired is allowed to be used exceptionally when a predetermined restoration condition is satisfied. Hereinafter, an example of the restoration condition will be described.

(Revival condition example 1)
In example 1 of the revival condition, when there is a new additional purchase of additional purchased communication capacity between the expiration of the usage period and the elapse of a predetermined period, the additional purchase communication capacity for the expired usage period is set to the communication capacity of the additional capacity. Add to the remaining amount. An example 1 of this restoration condition will be described. First, when the additional purchase processing unit 16 performs a process of performing a new additional purchase of the additional purchased communication capacity, the line number for which the new additional purchase has been made is used from the additional purchased communication capacity management data and the expired portion Specify the remaining capacity of. If there is a remaining capacity for the expiration date as a result of this specific determination, it is determined whether the remaining capacity for the expiration date is within a predetermined period. As a result of this determination, if the elapsed time from the expiration date is within a predetermined period, the additional purchased communication capacity management data is updated so that the remaining capacity of the expiration date can be used until the predetermined expiration date. To do. At this time, all of the remaining capacity for the expiration date may be used, or only a part (for example, a predetermined ratio (for example, 50%)) of the remaining capacity for the expiration date may be used. It may be.

  According to the above-described reversion condition example 1, the additional purchase communication capacity corresponding to the expired use period can be used with the predetermined use period under the condition of a new additional purchase of the additional purchase communication capacity. Moreover, the effect of prompting the user to newly purchase additional additional communication capacity can be obtained according to the condition of new additional purchase of additional purchased communication capacity.

(Revival condition example 2)
In the example 2 of the revival condition, when the remaining amount of additional purchased communication capacity is used from the expiration of the usage period until the elapse of a predetermined period, the additional purchased communication capacity for the expired usage period is set to the communication capacity of the predetermined usage period. Add to the remaining amount. An example 2 of this restoration condition will be described. First, when an update that consumes the remaining capacity within the expiration date is performed on the additional purchased communication capacity management data, the line number that has consumed the remaining capacity within the expiration date is used from the additional purchased communication capacity management data. Identify the remaining capacity of the expired usage. If there is a remaining capacity for the expiration date as a result of this specific determination, it is determined whether the remaining capacity for the expiration date is within a predetermined period. As a result of this determination, if the elapsed time from the expiration date is within a predetermined period, the additional purchased communication capacity management data is updated so that the remaining capacity of the expiration date can be used until the predetermined expiration date. To do. At this time, all of the remaining capacity for the expiration date may be used, or only a part (for example, a predetermined ratio (for example, 50%)) of the remaining capacity for the expiration date may be used. It may be.

  According to the above-described revival condition example 2, the additional purchased communication capacity for the expired usage period can be used for the predetermined usage period under the condition that the remaining capacity within the usage period of the additional purchased communication capacity is used. In addition, the use of the remaining capacity within the expiration date of the additional purchased communication capacity promotes the use of the unused capacity of the additional capacity within the expiration date of the additional purchased communication capacity. The effect of leading to additional purchases can also be obtained.

[Exceptional handling of communication permission]
Next, an example of exceptional processing for permitting communication according to the present embodiment will be described. The wireless communication line 106 according to the present embodiment may not be permitted in principle if there is no remaining capacity depending on the content of the contract. However, this principle alone may cause inconvenience that the user cannot access the additional purchase site of the additional purchased communication capacity from the terminal 102 using the wireless communication line 106 in order to make a new additional purchase of the additional purchased communication capacity. . Therefore, in the present embodiment, the remaining capacity management unit 12 permits communication with the additional purchase site of the additional purchased communication capacity regardless of the remaining capacity of the communication capacity. An exceptional process for permitting this communication will be described.

  When the communication control device 112 inquires of the communication capacity management device 1 about communication permission for the inquiry line number, information on the communication partner of the communication relating to the inquiry line number (here, the destination IP address is taken as an example). ). Upon receiving the notification, the communication capacity management device 1 determines whether the communication partner is an additional purchase site for additional purchase communication capacity based on the information of the communication partner. In this determination, it is determined whether the IP address of the additional purchase site with the additional purchase communication capacity matches the destination IP address notified from the communication control device 112. The IP address of the additional purchase site of the additional purchased communication capacity is set in the communication capacity management apparatus 1 in advance. As a result of the determination, if the IP addresses match, the communication capacity management device 1 notifies the communication control device 112 of communication permission using the communication permission information. On the other hand, if the IP addresses do not match, the communication capacity management device 1 transmits communication permission information based on the normal remaining capacity to the communication control device 112.

  According to the above-described exceptional processing for permission of communication, the terminal 102 can use the wireless communication line 106 to access the additional purchase site of the additional purchase communication capacity regardless of the remaining capacity, so that the convenience for the user is improved. In addition, the effect of promoting the additional purchase of the additional purchase communication capacity can be obtained.

[Provision of recommended additional purchases]
The remaining capacity management unit 12 outputs information on the recommended additional purchase amount of the additional purchase communication capacity based on the use history of the communication capacity for each line number. A method of providing this recommended additional purchase amount will be described. The remaining capacity management unit 12 records the usage history of the communication capacity for each line number. As the usage history of the communication capacity, for example, the amount of transfer data per day can be mentioned. The transfer data amount is indicated by transfer data amount information transmitted from the communication control device 112 to the communication capacity management device 1. The remaining capacity management unit 12 calculates the recommended additional purchase amount of the additional purchased communication capacity from the use history of the communication capacity for each line number. As a method of calculating this recommended additional purchase amount, for example, the communication capacity (total value of the transfer data amount for one month) used in one month (period of granting of regular grant communication capacity) is calculated, and this calculated value A value obtained by subtracting a single provision amount from the regular provision communication capacity from the above is used as the recommended additional purchase amount. Alternatively, the total value of the transfer data amount for the month may be used as guide information for the recommended additional purchase amount. Further, the recommended additional purchase amount may be obtained based on the past additional purchase record value of the communication capacity. Another recommendation is to recommend a communication capacity according to the frequency of access to a site that provides a large amount of content such as a moving image. Information on the access destination and access frequency is acquired from the communication control device 112. Information on the recommended additional purchase amount of additional purchase communication capacity is provided to the user. For example, information on the recommended additional purchase amount may be sent to the user terminal 102 by electronic mail. Accordingly, the user can determine how much additional purchase communication capacity should be purchased based on the information about the recommended additional purchase amount.

[Additional purchase processing of additional purchase communication capacity]
The additional purchase processing unit 16 performs processing for additional purchase of additional purchase communication capacity. Specifically, the additional purchase processing unit 16 inquires of the payment device 116 about the payment status of the payment for the additional purchase application in response to the additional purchase application for the additional purchase communication capacity from the user. The additional purchase processing unit 16 permits the additional purchase application when the result of the inquiry about the settlement status is completion of the settlement. If the payment has not been completed, the application for additional purchase is not permitted. The additional purchase processing unit 16 notifies the remaining capacity management unit 12 of the contents of the permitted additional purchase application (line number, user ID, purchase number, additional purchase communication capacity for new additional purchase, expiration date). The remaining capacity management unit 12 updates the corresponding additional purchase communication capacity management data based on the notified contents of the additional purchase application.

  In the above-described method for determining permission for additional purchase, permission is made on the condition that payment for the additional purchase application is completed, but a condition for permission may be further added. Hereinafter, examples of conditions for permitting additional purchase will be described.

(Example of additional purchase permission conditions)
The additional purchase processing unit 16 determines whether or not the additional purchase is possible based on the attribute of the user associated with the wireless communication line that is the target of the additional purchase of the communication capacity with the expiration date. An example of the additional purchase permission condition will be described. First, the additional purchase processing unit 16 determines the user attribute associated with the line number that is the target of the additional purchase communication capacity additional purchase based on the application for additional purchase of the additional purchase communication capacity from the user as the user contract information. The management device 114 is inquired. The user contract information management apparatus 114 has information indicating user attributes as user contract information. The additional purchase processing unit 16 determines whether to permit the additional purchase application based on the user attribute obtained as a result of the inquiry. Examples of this criterion are given below.
(Example of criteria 1)
When the user attribute is “child”, an additional purchase application in which the remaining capacity for the line number exceeds a predetermined amount is not permitted.
(Judgment criteria example 2)
When the user attribute is “child”, the additional purchase application is permitted when there is a predetermined password as information included in the additional purchase application, and the additional purchase application is not permitted when there is no password. Thereby, it is possible to prevent a child from making additional purchases freely through parental control by using a password that is not a parent as the password.

  The above is an example of the additional purchase permission condition.

Moreover, the example of the additional purchase method at the time of a user purchasing additional communication capacity is given below.
(Example 1 of additional purchase method)
A plurality of additional purchase plans having different communication capacities for additional purchase are set, and a menu is provided for the user to select an arbitrary additional purchase plan from the plurality of additional purchase plans. The additional purchase processing unit 16 updates the corresponding additional purchase communication capacity management data according to the additional purchase plan selected in the menu.

(Example 2 of additional purchase method)
The communication capacity at the time of additional purchase is set to be different from the amount of provision of the regularly granted communication capacity.

(Example 3 of additional purchase method)
A menu that allows the user to specify the communication capacity to be additionally purchased is provided, and the additional purchase processing unit 16 updates the corresponding additional purchased communication capacity management data in accordance with the communication capacity specified in the menu.

(Example 4 of additional purchase method)
The additional purchase communication capacity is set so that the expiration date varies depending on the amount of additional purchase. For example, the expiration date is set so as to increase as the amount of additional purchase increases.

(Example 5 of additional purchase method)
Assume that the payment method for additional purchase of communication capacity may be either prepaid or postpaid.

[Other Embodiments]
Next, a modification of the communication capacity management device 1 according to the above-described embodiment will be described.

The shared processing unit 32 updates the shared management data stored in the shared management data storage unit 34 in response to an application for sharing the communication capacity among a plurality of wireless communication lines.

  FIG. 11 is a diagram illustrating a configuration example of shared management data. In FIG. 11, the shared management data includes a line number, a user ID, and a shared setting identifier (shared setting ID) for each line number. The common setting ID is given to the line number with common communication capacity. The same sharing setting ID is assigned to a plurality of line numbers belonging to the same group sharing the communication capacity.

  In the example of FIG. 11, a plurality of line numbers belonging to the same group sharing the communication capacity are associated with the same user ID. For example, the same shared setting ID_0001 is assigned to the two line numbers “090-XXXX-0002” and “090-XXXX-0003” of the user ID “ID_2”. Accordingly, the remaining capacity management unit 12 adds up the remaining capacity within the expiration date of each line number indicated by the remaining capacity management data for the line numbers “090-XXXX-0002” and “090-XXXX-0003”. Manage the remaining capacity. Specifically, the remaining capacity management unit 12 determines the remaining capacity of the line numbers “090-XXXX-0002” and “090-XXXX-0003” based on the total remaining capacity in step S21 of FIG. A determination is made, and the communication permission information in step S22 is transmitted from the determination result. Therefore, for example, even if there is no remaining capacity within the expiration date of the inquiry line number “090-XXXX-0002”, if there is a remaining capacity within the expiration date of the line number “090-XXXX-0003”, communication is permitted. With the information, the communication control apparatus 112 is notified of communication permission for the inquiry line number “090-XXXX-0002”. In addition, the remaining capacity management unit 12 reduces the consumption based on the transfer data amount information of each line number from the total remaining capacity for the line numbers “090-XXXX-0002” and “090-XXXX-0003”. According to the example of FIG. 11, the communication capacity can be shared among a plurality of line numbers with which the same user has a contract.

  FIG. 12 is a diagram illustrating another configuration example of the shared management data. In the example of FIG. 12, among the plurality of line numbers belonging to the same group sharing the communication capacity, the first line number and the second line number are associated with different user IDs. For example, the same shared setting ID_0001 is assigned to the line number “090-XXXX-0001” of the user ID “ID_1” and the line number “090-XXXX-0002” of the user ID “ID_2”. As a result, the remaining capacity management unit 12 sets the line numbers “090-XXXX-0001” and “090-XXXX-0002” for each line number indicated by the remaining capacity management data as in the example of FIG. Manage the total remaining capacity, which is the total remaining capacity within the expiration date. According to the example of FIG. 12, it is possible to share the communication capacity between different users. For example, it is possible to share the communication capacity of the line number contracted by the parent and child in the family. Alternatively, it is possible to share the communication capacity of the line number with which each user of the same billing group who pays for the communication service is contracted.
