Next, a charging procedure in the rental server charging system of the first embodiment will be described with reference to FIG. FIG. 11 is an operation procedure diagram showing a charging processing procedure in the rental server charging system of the present embodiment.

The information referrer terminal 31 is connected to the information providing server 1
11 (step 10), the information providing server 111 transmits the content 111a and the like to the information reference terminal 31 (step 11). The access history is recorded in a log file (step 12). At this time, the contents to be recorded in the log file include, for example, FIG.
Server ID, user ID, content I
D, a content serial number, an access date and time, and the like can be considered.

Of course, it is also possible to record and hold a finer classification than this, and in some cases, even if the number of fields is further reduced, for example, by omitting the content ID, the system of the contents set in the fields can be appropriately adjusted. By doing so, correct processing can be performed. However, in a later procedure, it is necessary to hold a minimum required field for correctly grasping the daily and monthly data transfer amount for each user.

In particular, when an ID for each content is provided in the field layout of the log file, it is possible to notify not only the total data transfer amount for each user but also the data transfer amount for each content. Become. As a result, if the rental server user holds a plurality of contents in the rental server,
It is possible to grasp which content is popular and to use the content effectively.

Further, in the case where the log file field layout has a content serial number indicating a page of the content in addition to the content ID, for example, which page in a certain homepage is popular is collected. Can be grasped, and it becomes more effective.

The information totaling server 112 calculates a daily data transfer amount actual calculation based on the data recorded in the log file in the daily processing and the data of each content capacity (step 13). This daily data transfer amount actual calculation can be calculated, for example, by multiplying the number of accesses by the content capacity. At this time, it is preferable that the data of the content capacity is stored in a content capacity file or the like in advance, and is used in the daily data transfer amount actual calculation. This content capacity file may be stored in either the information providing server 111 or the information totaling server 112.

As a field layout of the content capacity file, for example, as shown in FIG.
D, user ID, content ID, content serial number, data capacity, and the like can be considered. Of course, in this case, it is also possible to record and hold a finer classification, and it is also possible to reduce the number of fields. However, as in the case of the log file, in a later procedure, it is necessary to hold a minimum necessary field for correctly grasping the daily and monthly data transfer amount for each user.

Next, the information totaling server 112 saves the calculated data transfer amount in the data transfer amount actual file (step 14). At this time, as a field layout of the data transfer amount actual file, for example, as shown in FIG. 4, a user ID, a content ID, an access date, a transfer amount, and the like can be considered.

Also in this case, the number of fields can be increased or decreased according to the accuracy of the information to be held. For example, by adding a field such as the number of times of access per day, it becomes possible to transmit not only the data transfer amount but also the number of times of access to the rental server user terminal 21. Also, by adding a content serial number indicating a content page for each content ID, for example, it is possible to grasp the data transfer amount for each page of the homepage.
From this information and the capacity of each content, the rental server user can grasp what content is popular, and can utilize it to create more frequently accessed content. In addition, by changing the access date to the access date,
It is also possible to grasp which pages are concentrated in access for each time zone. As a result, the rental server user can understand what kind of content is frequently accessed at what time,

Next, the information totaling server 112 automatically transmits the data transfer amount results and the like to the rental server user terminal 21 by means such as electronic mail (step 1).
5). At this time, in some cases, not only automatic transmission but also manual transmission such as mail transmission is possible.

Further, the information totaling server 112 performs monthly data transfer amount calculation based on the data of the data transfer amount actual file in monthly processing (step 1).
6). This is possible by summing up the daily data.

Then, the billing amount is determined based on the calculation result of the actual data transfer amount. For example, the charge amount is reflected on the charge amount by, for example, making the charge amount proportional to the monthly data transfer amount result (step 17). At this time, the field layout of the log file and the data transfer amount actual file includes
If D is set, it is also possible to obtain a billing amount for each content and make a bill. Thereby, the rental server user can grasp the cost effect for each content.

Lastly, the monthly data transfer amount and the rental server usage charge are stored in the rental server user terminal 21.
Then, it is automatically transmitted by e-mail or other means (step 18). At this time, in some cases, it is also possible to manually send the bill, the monthly data transfer amount, and the like by mail or the like.

Here, the transmission destinations of the monthly data transfer amount record and the rental server use billing amount are not necessarily limited to the rental server user terminal 21, but may be, for example, a mobile phone or the like held by the rental server user. Any other terminal may be used as long as it has a function of receiving the actual monthly data transfer amount transmitted from the information totalizing server 112 and the rental server usage charge. Furthermore, it is also preferable to set a plurality of transmission destinations, such as setting the other terminal in addition to the rental server user terminal 21.

If the charging procedure in the rental server charging system is in this order, the rental server user is charged for the rental usage fee based on the access to the content provided on the rental server. Therefore, cost efficiency can be improved.

At this time, it is preferable to provide the information totaling server 112 with a dedicated screen for referring to the data transfer amount and the charge amount up to the time of the access.

The information totaling server 112 responds to a request for referring to the data transfer amount up to the time of the access and the billing amount.
The actual data transfer amount regarding the contents of the rental server user is calculated based on the data of the log file and the content capacity file (step 14).

At this time, as in the case of the first embodiment, the calculation can be performed for each predetermined unit according to the field layout of the log file. For example, in the field layout of the log file,
If D is set, the data transfer amount can be calculated for each content, and the calculation result can be transmitted to each rental server user.

Next, the information totaling server 112 saves the calculated data transfer amount in the data transfer amount actual file (step 15), totals the data accumulated in the data transfer amount actual file, and obtains the data transfer amount. Is calculated (step 16), and the billing amount is calculated based on the sum (step 17).

Here, the data transfer amount record is once stored in the data transfer amount record file, and then the data transfer amount record is totaled. However, the data transfer amount calculation result is obtained without storing the data. The data transfer amount up to the present may be calculated by totalizing the data up to the previous day stored in the data transfer amount actual file.

The information totaling server 112 transmits the actual data transfer amount (total value) and the billing amount thus obtained to the rental server user terminal 21 (step 1).
