[0007]

FIG. 1 is a block diagram showing an embodiment of a billing system according to the present invention.

Referring to FIG. 1, this embodiment includes a center 100, a terminal 1 that is a wired communication terminal, a wired communication network 2 (for example, the Internet) connecting the center 100 and the terminal 1, Terminal 9 and center 100
And a wireless communication network 10 connecting the terminal 9 to the terminal 9.

The center 100 connects the form storage server computer 3 (hereinafter referred to as "Web server"), the mail server computer 5, the billing management server computer 7, the information management server computer 11, and these server computers. A local area network (LAN) 13. (Hereinafter, the “server computer” is simply referred to as a “server.”) In the center 100, the Web server 3, the mail server 5, the billing management server 7, and the information management server 11 are a form storage memory 4, a mail storage memory 6, respectively. , Is directly connected to the billing memory 8 and the storage memory 12.

[0010] The charging memory 8 includes a usage fee table. In this usage fee table, fees corresponding to each form identification and each communication method identification are registered.

FIG. 6 is a diagram showing the structure of the billing memory 8.

The billing memory 8 stores a usage fee table 61.
And a usage fee storage unit 62 assigned to each user.

The communication between the Web server 3 and the originating terminal 1 is performed via a communication network 2 via a hypertext transfer system.
Protocol (Hyper-Text Transfer Protocol (HTT)
P)). The form storage memory 4 of the Web server 3 has a hypertext markup language (Hy
A plurality of form data described in per-Text Markup Language (HTML) are stored, and each form data is assigned a unique file name.

First, a user inputs a file name of desired form data to the terminal 1. When the terminal 1 sends the input file name to the Web server 3, the Web server 3 accesses the form storage memory 4, reads out the form data corresponding to the input file name, and sends it to the terminal 1.
Of course, the form data can be obtained from the form storage memory in advance, and the terminal 1 can store the form data in advance.

FIG. 2 shows an example in which certain form data stored in the memory 4 is displayed on the screen of the terminal 1. This form data is referred to as “postcard form data”.

In FIG. 2, on a screen 21 of the terminal 1, a picture area 27 corresponding to the front of a postcard and a character area 25 corresponding to the back are displayed. The character area 25 includes a communication method display column 22 such as a “normal mode”, a “express delivery mode”, and a “writing mode”, and a usage fee display column 26 for displaying a usage fee.

The fee to be displayed in the usage fee display column 26 is
It can be known by referring to the usage fee table in the terminal 1 in which the fees corresponding to each form identification and each communication method are registered. This usage charge table is sent from the charging memory 8 of the charging management server 7 to the terminal 1 via the Web server 3 when the terminal 1 retrieves the form data from the form storage memory.

Further, the character area 25 is provided with a destination field 23 and a communication information writing field 24. When a user inputs an e-mail address of a transmission destination and information to be transmitted to these fields 23 and 24, respectively, It is sent to the center 100 as one electronic mail.

FIG. 3 is a diagram showing a data structure of an electronic mail.

As shown in FIG. 3, an e-mail is composed of an address information section including an address 31, a sender address 32, a destination address 34, etc. of the mail server 5, which is a direct destination at the time of transmission, and a communication of the sender. In addition to the data 35, a header part has a form identifier 33. The form identifier 33 includes information for identifying each form and information relating to the service selected in the service selection field 28.

The address 31 of the mail server 5 can be specified by the user himself at the transmitting terminal 1 or
The address of the mail server 5 stored in advance is automatically written at the time of transmission. Sender address 32
The same applies to. The destination address is set by the user at the transmitting terminal 1 before transmission.

FIG. 4 is a diagram showing the structure of the form identifier 33. This identifier 33 is stored in the form identification unit 41.
, A communication method identification unit 42, a designated time unit 43, a postmark time unit 44, and a posting period unit 45.

An identifier for identifying a form is set in the form identification section 41. In the above example, an identifier indicating “postcard form data” is set. In FIG. 2, when the user selects a communication method from a service selection field 28 for selecting “normal mode”, “express delivery mode”, “writing mode”, etc. displayed on the screen 21, the user selects the communication method. The result is displayed in the communication method display column 22 and registered in the communication method identification unit 42 as an identifier of the communication method.

As a communication procedure between the terminal 1 and the mail server 5, an e-mail protocol such as a Simple Mail Transfer Protocol (SMTP) can be used.

First, a case where the transmission method selected by the user is the transmission of an “ordinary mode” e-mail using the most basic service “postcard form” will be described.

First, the user obtains the “postcard form” from the form storage memory 4 via the terminal 1. If the terminal 1 already has it, use it. Then, as a communication method, after selecting "normal mode" in the service selection field 28 of the "postcard form" displayed on the screen of the terminal 1, the e-mail address of the transmission destination is entered in the destination field, and the communication information is written in the communication information writing field. Write the information you want to convey and send it out as an e-mail.

In this manner, the mail addressed to terminal 9 transmitted from terminal 1 to mail server 5 is temporarily stored in mail storage memory 6. Information management server 11 is LA
The mail storage memory 6 is periodically referred to via N13,
It checks whether new mail has arrived, and if new mail has arrived, reads that mail. At this time, the read mail is deleted from the mail storage memory 6.

The information management server 11 recognizes the communication method by referring to the form identifier 33 of the read mail. The information management server 11 transfers the read mail to the storage memory 12.

FIG. 5 is a diagram showing the structure of the contents stored in the mail storage memory 12. The mail storage memory 12 includes a user identifier storage unit 51, a new arrival storage unit 52, and a storage storage unit 5.
3 inclusive.

The mail transferred from the information management server 11 is stored in the new arrival storage unit 52. The user of the terminal 9 accesses the information management server 11 from the terminal 9 via the communication network 2 in a timely manner, reads out the e-mail stored in the new arrival storage unit 52 assigned to the terminal 9 of the storage memory 12, and reads the e-mail. Request the information management server 11 to transfer.

The information management server 11, which has read the e-mail from the new arrival storage unit 52 at the request of the terminal 9, transmits the e-mail to the terminal 9, and also transmits the form identifier 33 and the sender address 32 included in the e-mail. It is transmitted to the charge management server 7 as charge information. Upon receiving the billing information from the information management server 11, the billing management server 7 refers to the usage fee table in the billing memory 8 of the billing management server 7, and uses the form identification 41 and the communication method identification 42 in the billing information. Charges memory 8
Then, it is stored for each user based on the sender address in the billing information.

Here, the information management server 11 and the receiving terminal 9
Since the communication network 10 is a wireless network, the communication may be forcibly disconnected before the receiving terminal 9 normally receives the e-mail due to a wireless state or the like.

For this reason, the communication protocol between the terminal 9 and the information management server 11 uses a protocol with retransmission control and acknowledgment, and automatically reconnects to continue reading even if there is a line disconnection. Reliability. Upon receiving the e-mail normally, the terminal 9 transmits reception completion information to the information management server 11. As described above, if the communication is forcibly disconnected before the receiving terminal 9 normally receives the e-mail, the reception completion information is not transmitted from the reception terminal 9, and the information management server 11 receives the reception completion information. Resend this e-mail until:

In this case, the information management server charges only when the e-mail is first transmitted to the receiving terminal 9, and does not charge the e-mail when resending.

The communication processing and the billing processing relating to the basic service corresponding to ordinary mail have been described above. Other services will be described below.

Other services include "express delivery", "writing down", "direct mail (copy delivery)", "posting", and the like.

Next, a case where the communication method selected by the user is transmission of an e-mail in the "express delivery mode" will be described.

First, the user obtains a form to be used from the form storage memory 4 via the terminal 1. In addition,
If the terminal 1 already has it, use it. Then, as the communication method, after selecting "Express delivery mode" in the service selection field 28 of the form to be used displayed on the screen of the terminal 1, the e-mail address of the transmission destination is input in the destination field and transmitted to the communication information writing field. Write the information you want and send it out as an e-mail.

In the "express delivery mode", the information management server 11 transfers the electronic mail from the terminal 1 to the mail storage memory new arrival storage unit 52 of the user of the terminal 9 which is the communication partner from the mail server 5 in the "ordinary mode" described above. When the information is transferred, the information management server 11 transmits a reception signal indicating the reception to the reception terminal 9. The receiving terminal 9 that has received the incoming signal responds to the incoming call, recognizes the information management server 11, and reads out the mail from the new arrival storage unit 52 of the storage memory 12 of the information management server 11.

At this time, the information management server 11 notifies the accounting server 7 of the accounting information.

When the billing information is transmitted, the billing management server 7 refers to the billing information table in the billing management server 7 and stores the usage fee corresponding to the form identifier 33 in the billing information in the billing memory 8 and the billing information. It accumulates for each user based on the sender address inside.

If the information processing server 11 cannot confirm the incoming call response from the partner terminal 9, any one of the following processes is performed. The first process is to send a mail notifying the non-delivery to the originating terminal 1. The second process is to change the communication method to the “normal mode”. Specifically, the content of the communication method identification of the form identifier 33 is rewritten. The third process is to notify the sending terminal of the non-delivery and discard the e-mail in the storage memory 12.

These processes can be performed by setting in advance between the user and the operator of the center. Also,
This process can be performed by adding an additional identifier to the identifier of the “express mode”.

When the first process is performed, a mail indicating non-delivery is sent to the transmitting terminal 1, and when the second process is performed, the receiving terminal 9 reads the e-mail from the information management server 11. At the time of performing the third process, when discarding the e-mail, the information management server 11 notifies the billing management server 7 of the billing information for these processes.

It should be noted that the fee for performing the first to third processes is lower or free compared to the case where the electronic mail is normally transmitted in the "express delivery mode".

Further, a service called "time designation transmission" can be executed by applying the "express delivery mode".

First, the user obtains a form to be used from the form storage memory 4 via the terminal 1. In addition,
If the terminal 1 already has it, use it. Then, as the communication method, after selecting "time designation transmission" in the service selection field 28 of the form to be used displayed on the screen of the terminal 1, the e-mail address of the transmission destination is entered in the destination field. Also enter the time you want to send. When the time to be sent is input, the information is registered in the designated time section 43 of the form identifier 33. Then, write the information you want to transmit in the communication information writing column,
Send as e-mail.

In the case of “time designation transmission”, the mail server 5
The information management server 11 periodically reads the e-mail that has arrived. At this time, the information management server 11 determines whether or not the time indicated by the clock incorporated in the information management server 11 has reached the value written in the designated time section 43 of the form identifier 33. If the specified time has not been reached, the information management server 11 returns this e-mail to the mail server 5.

If the recipient has not received the e-mail because the recipient did not access the information management server until the designated time, the same processing as in the "express delivery mode" is performed. That is, the receiving terminal 9 transmits the incoming signal indicating the incoming call to the receiving terminal 9, and the receiving terminal 9 receiving the incoming signal responds to the incoming signal, recognizes the information management server 11, and stores the newly received information in the storage memory 12 of the information management server 11. The mail is read from the unit 52. At this time, the information management server 11 stores in the charging memory 8 the charging set as “time-specified transmission”.

Next, a case will be described in which the communication method selected by the user is transmission of an e-mail in the "writing mode".

The user uses the “postcard form” obtained from the form storage memory 4 or built in the terminal 1. Then, select a communication method of "writing mode" in a service selection field of a "postcard form" displayed on the screen of the terminal 1, enter an e-mail address of a transmission destination in a destination field, and write information to be transmitted in a communication information writing field. send. The information management server 11 transmits the e-mail transmitted from the terminal 1 via the mail server 5 to the terminal 9
And the form identifier included in the e-mail is transmitted to the charge management server 7 as charge information. The charging management server 7 refers to the usage fee table in the charging memory 8 of the charging management server 7, and stores the usage fee corresponding to the form identification 41 and the communication method identification 42 in the charging information in the charging memory 8 and the usage fee in the charging information. It is stored for each user based on the sender address. In the “writing mode”, when the information management server 11 receives the reception completion information from the reception terminal 9, the information management server 11 notifies the transmission terminal 1 of the transmission by transmitting a transmission confirmation notification as an e-mail to the sender address. Since the information management server 11 has a built-in clock, the time information can be included in the delivery confirmation notification. In the above service,
The information management server 11 sends an e-mail to the receiving terminal 9, transmits billing information of the e-mail to the billing management server 7, and receives the billing information from the billing management server 7.
Has charged the charge of this e-mail to the charging memory 8 for each user, and did not charge information when resending the e-mail. In the present invention, the form of billing may be as follows. In this embodiment, the information management server 11 transmits an e-mail to the receiving terminal 9, and when receiving the reception completion information from the receiving terminal 9, transmits the charging information to the charging management server 7. As a result, charging is performed only when the receiving terminal 9 normally receives the electronic mail from the information management server 11. The reception completion information transmitted from the reception terminal 9 to the information management server 11 includes the sender address 32 and the form identifier 33 included in the e-mail transmitted from the information management server 11 to the reception terminal 9.

Next, a case will be described in which the transmission method selected by the user is transmission of an electronic mail in the “direct mail mode” using the “postcard form”.

The user uses the “postcard form” obtained from the form storage memory 4 or built in the terminal 1. Then, the user selects the communication method of "direct mail mode" in the service selection field of the "postcard form" displayed on the screen of the terminal 1, inputs a special representative destination indicating a plurality of destinations in the destination field, and writes the communication information. Write the information you want to convey in the field and send it out.

When using the direct mail mode, the sender needs to register a special representative destination indicating a plurality of destinations in the information management server in advance. The e-mail having this representative destination is sent to the information management server 1
When 1 is read, the information management server 11 copies and transfers the electronic mail to the newly arrived storage memory 52 for all the registered destinations.

In this case, the information management server 11 notifies the accounting server 7 of accounting information corresponding to the number of copies at the time of copying and transfer,
The accounting management server charges the transmission source.

Further, when copying and transferring to the storage memory new arrival storage unit 52, the postmark time unit 44 corresponding to the postmark of the post is written in the form identifier 33, and the information management server 11 performs the postmark in the arrival arrival unit of the new memory of all users. It is also possible to automatically delete emails that have passed a certain period of time from the time.

Next, a case will be described in which the transmission method selected by the user is transmission of an electronic mail in the “post mode” using the “postcard form”.

In the "posting mode", posting can be performed for a limited period.

The user uses the “postcard form” obtained from the form storage memory 4 or built in the terminal 1. Then, the user selects a "posting mode" communication method in the service selection field of the "postcard form" displayed on the screen of the terminal 1, inputs a desired posting period, and writes and transmits information to be transmitted to the communication information writing column.

When a desired posting period is input, it is registered in the posting period section 45 of the form identifier 33.

The e-mail sent from the terminal 1 in the “post mode” is sent to the information management server 11 via the mail server 5.
Is transmitted to a posting memory provided with a user identifier 51 which is accessible from a plurality of users and is provided in the storage memory 12.

The posting period section 45 includes a preset time parameter which decreases by a predetermined value every unit time indicating the posting period. The decrease of the time parameter starts when the electronic mail is sent to the bulletin memory.

The information management server 11 sets the time parameter to 0.
The charge information is sent to the charge management server 7 every time the unit time elapses.

If the terminal 9 requests the terminal 9 to send an e-mail in the posting memory before the time parameter becomes 0, the information management server 11 copies this e-mail and sends it to the terminal 9. .

When the time parameter becomes 0, the information management server 11 deletes the electronic mail from the storage memory 12.

In the above embodiment, the terminal 1 is a wired communication device, the terminal 9 is a mobile wireless communication device, the communication network 2 is a wired communication network, and the communication network 10 is a wireless network. However, each terminal may be a stationary terminal, or each communication network may be a wired network or a wireless network.

[0067]

As described above, the present invention has an effect that it is possible to prevent charging when reconnecting after disconnecting the line when sending an e-mail via a wireless network. In addition, since a plurality of electronic forms prepared in advance are set for each communication method, there is an effect that a clear charge is charged to the user.
