Abstract

PROBLEM TO BE SOLVED: To apply a prepayment charging system to communication, using a subscriber terminal which is not provided with a prepayment dealing configuration or the like by storing communication enable data for each subscriber and forcedly halting the communication, when the subtracted remainder data become zero during communication execution. SOLUTION: A central control unit, to which call origination information from a certain subscriber terminal 2 to a call terminating terminal is applied, first extracts the remainder data and discriminates whether the remainder data are '0' by accessing a charging DB 4a with data showing the telephone number of the subscriber terminal 2 which originates a call. When the remainder data are '0', the central control unit starts a message voice trunk and transmits the voice message of 'connection cannot be made, since the remainder is zero' to the subscriber terminal 2 which originated the call, and after the lapse of a prescribed time such as two seconds, disconnecting processing is performed. During this processing period, a subtraction processing part 4f subtracts an appropriate amount of the remainder corresponding to the call time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber type communication system for charging a subscriber who is providing communication according to a communication time and the like, and is applicable to, for example, a telephone communication system or the Internet.

[0002]

2. Description of the Related Art At present, a detailed recording method is mainly used as a billing method in a telephone communication system.

[0003] The detailed recording method includes a start time of each call,
In this method, the end time, the called number, the date, and the like are stored for each subscriber, and later calculated and counted using a computer. In the detailed recording method, a function of storing and transferring the charge details is provided to the subscriber line exchange accommodating the subscriber terminal, and the detailed information on each subscriber is transferred to the charge detail breakdown processing center via a signal transmission line. Then, the transfer information is processed in the charge detail breakdown processing center, and a charge in one-month units or the like is calculated.

[0004]

The conventional billing system including the detailed recording system is a post-payment system. Therefore, each subscriber cannot correctly grasp his / her telephone usage fee until the fee statement arrives.

[0005] However, there are many subscribers of telephone communication systems today, and some subscribers (including corporations) have budgets such as telephone charges. From the viewpoint of such a subscriber, the use of the post-payment method cannot limit or grasp the usage fee, so that the budget may be exceeded and the charging method may be dissatisfied.

[0006] For this reason, some subscribers desire a prepaid system. At present, as a prepaid system in a telephone system, there is a system using a prepaid card (so-called telephone card) for a public telephone, a pink telephone, or the like.

However, it is not conceivable that each subscriber will install a large telephone terminal having such a card processing mechanism.
Complicated work such as inserting a card is required.

[0008] Further, in order to charge, it is necessary to register the information of the subscriber (customer) in a database such as a charging database, but in a telephone communication system or the like, a subscriber who needs new registration per day is required. There are many, and the registration work is very complicated. Furthermore, registration in such a database takes time, and it takes time for a new subscriber to start communication.

[0009] The above-mentioned problems also occur in other subscriber communication systems such as the Internet.

[0010] Therefore, there is a demand for a subscriber-type communication system that can apply a prepaid billing method to communication using a subscriber terminal that does not have a prepaid support configuration or the like.
There is also a need for a subscriber-type communication system that can register customer information and the like in a database quickly and automatically.

[0011]

In order to solve the above-mentioned problems, the present invention according to a first aspect of the present invention provides a subscriber type communication system which charges a subscriber who is providing communication according to a communication time or the like. It is characterized by having.

[0012] That is, (1) charging data storage means for storing communicable balance data for each subscriber, and (2) prepaid amount information input means for inputting amount data deposited for a certain subscriber. (3) When the amount data input by the prepaid amount information input means is received by communication, it is added to the balance data for the subscriber stored in the charging data storage means, and A balance updating means to be re-stored in the data storage means; and (4) taking out the balance data stored in the billing data storage means at the start of communication, reducing the balance data during communication, and (5) When the balance data becomes 0 during the execution of the communication, the communication is started. And having a communication abort means for braking terminated.

According to a second aspect of the present invention, in the subscriber communication system according to the first aspect of the present invention, the balance updating means stores the amount data of the subscriber not stored in the charging data storage means. Is received, an area for the subscriber is secured in the charging data storage means, and the amount data is stored as balance data.

According to a third aspect of the present invention, in the subscriber type communication system according to the first or second aspect of the present invention, the amount information input means performs an input process by reading a form. However, it is characterized in that a sheet on which the amount data and the subscriber identification data are described is affixed, and the data portion required for other payment processing is printed from the beginning.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) First Embodiment Hereinafter, a first embodiment in which a subscriber communication system according to the present invention is applied to an international telephone communication system will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the overall configuration of the telephone communication system according to the first embodiment.

In FIG. 1, a telephone communication system 1 according to a first embodiment includes a subscriber terminal (telephone terminal) 2, a domestic network 3,
It includes a domestic and foreign exchange (hereinafter simply referred to as an exchange) 4, an international network 5, a payment form processing device 6, and a payment information processing device 7.

In the case of the first embodiment, the subscriber terminal 2
A general telephone terminal may be used as long as it can execute the caller ID notification, and does not need to have a special function or configuration in consideration of a prepayment method as described later. The exchange 4 basically exchanges between the domestic network 3 and the international network 5. A general exchange configuration can be applied to the exchange configuration itself between the domestic network 3 and the international network 5 in the exchange 4. That is, although not shown, a central control device for controlling the whole of the exchange, such as a domestic network side trunk, an international network side trunk, a switch unit for performing switching between these trunks, and a switch unit. (CPU).

In the case of this embodiment, the exchange 4 differs from the conventional exchange in the configuration related to charging. The exchange 4 includes a charging database (charging DB) 4a, a customer database (customer DB) 4b, and a regional fee database (regional fee DB) 4c, and is provided in association with a subscriber letter creating device 4d. ing. The billing database 4a, the subscriber database 4b, the regional fee database 4c, and the subscriber letter creation device 4d are:
It may be provided in a data management center located at a different position from the exchange 4.

The billing database 4a stores balance data for each subscriber (amount that can be talked out of prepaid) and usage details data. The customer database 4b stores, for example, telephone number data in association with the name and address data of the subscriber. The regional charge database 4c stores data of a basic charge per predetermined time (or a possible call time per basic charge) determined by a regional difference between a calling terminal and a called terminal and a call time. Subscriber letter creation device 4d
Under the control of the central control unit, a letter to the subscriber who prompts for payment of the fee (a deposit form described later may be included) is created.

Further, the exchange 4 has, as a billing structure, for example, a balance setting unit 4e in which the prepaid balance data of the subscriber at the time of calling is set, and basic charge data per predetermined time during a call (or And a subtraction processing unit 4f for subtracting the basic charge data defining the communicable time from the balance data of the balance setting unit 4e at every predetermined time (or every communicable time per basic charge). These balance setting unit 4e and subtraction processing unit 4f do not necessarily need to be configured with a hardware configuration, but may be configured with a software configuration.

The balance data set in the balance setting section 4e is for the calling subscriber stored in the charging database 4a. The basic charge data to be subtracted by the subtraction processing unit 4f is extracted from the regional charge database 4c.

The exchange 4 further includes a deposit information receiving unit 4g. The deposit information receiving section 4g receives the deposit information data from the deposit information processing device 7 and gives it to the central control device. The central control unit is a payment information receiving unit 4g.
When the payment information data is given via the server, the storage contents of the charging database 4a are updated as described later.

The payment form processing device 6 processes a payment form related to prepayment. The payment form processing device 6 includes, for example, a convenience store (a so-called convenience store),
It is installed at the head office, branch office, agency, etc. of the telephone service provider (it will be described below that it is installed at a convenience store). The deposit form processing device 6 is roughly composed of a barcode issuing unit 6a, a deposit form reading unit 6b, and a deposit information transmitting unit 6c.

In the case of this embodiment, the deposit form includes at least a telephone number code,
It includes a deposit amount (prepayment amount) code, a financial institution (eg, finance company) code, and a telephone service provider (and / or agency) code. Here, the financial institution code and the telephone service providing company code are printed in advance on the payment form.

The bar code issuing section 6a issues a bar code of a telephone number code and a stored amount code. The issued telephone number code and bar code of the stored amount code are affixed to predetermined positions of the payment form, and the payment form to be read is completed. After receiving the prepaid amount, the clerk of the convenience store issues a telephone number code and a stored amount code barcode by the barcode issuing unit 6a, and replaces the issued telephone number code and stored amount code with the barcode. Attach it to a specified position on the deposit form.

The payment form reading unit 6b reads the payment form, and transmits the obtained code and data specifying the payment form reading unit 6b (in other words, data specifying the convenience store) to the payment information. This is given to the unit 6c.

The deposit information transmitting section 6c includes a deposit form reading section 6
The data given from b is transferred to the deposit information processing device 7.

The deposit information processing device 7 has a money processing function,
It has a transfer function of payment information. The deposit information processing device 7 is, for example, one that is installed in a finance company. The deposit information processing device 7 includes a deposit information receiving unit 7
a, a storage processing unit 7b and a payment information transmitting unit 7c.

The deposit information receiving section 7a receives the deposit information data from the deposit form processing device 6, and gives it to the storing section 7b and the deposit information transmitting section 7c.

The storage processing unit 7b manages and aggregates the received payment information data, and creates data relating to the transfer of money between the head office of the convenience store and the telephone service provider.

The deposit information transmitting section 7c is provided with the deposit information receiving section 7
At least the telephone number code and the stored amount code are extracted from the deposit information data from a and transmitted to the exchange 4.

Next, the operation of the international telephone communication system according to the embodiment having the above configuration will be described.

First, the operation related to prepayment will be described.
The subscriber goes to the convenience store and pays the upfront amount. Accordingly, the clerk issues a bar code of the telephone number code of the subscriber and a bar code of the stored amount (prepaid amount) code by the bar code issuing unit 6a.
The bar code of the issued telephone number code and the stored amount code is attached to a predetermined position of the payment form, and read by the payment form reading unit 6b. Payment form reading unit 6
Data and the like obtained by b in the reading operation are transferred from the deposit information transmitting unit 6c to the deposit information processing device 7.

In the deposit information processing device 7, the transferred deposit information data is received by the deposit information receiving section 7a, and at least the telephone number code and the stored amount code are taken out by the deposit information transmitting section 7c. Transmitted to the exchange 4.

In the exchange 4, the deposit information receiving unit 4g
Receives the payment information data from the payment information processing device 7 and gives it to the central control device. At this time, the central control device executes the processing shown in FIG.

The central controller first determines whether or not data relating to the telephone number (subscriber) code included in the deposit information data exists in the charging database 4a (step 100).

As a result of this determination, when the central control unit obtains a result indicating that it does not exist, the central control unit secures (newly registers) an area of data relating to the telephone number (subscriber) code in the charging database 4a (step 101). Then, data relating to the stored amount code included in the transmitted payment information data is set as the balance data (step 102), and a series of processing at the time of receiving the payment information is completed.

On the other hand, the central controller obtains the result that the data relating to the telephone number (subscriber) code included in the deposit information data exists in the charging database 4a.
The balance data for the telephone number code is extracted from the charging database 4a (step 103), and the extracted balance data and the data relating to the stored amount code included in the transmitted deposit information data are added (step 104). , The balance data after the addition is stored in the charging database 4
a (step 105), and the process at the time of receiving the series of payment information is completed.

Next, the operation of the exchange 4 when a call is made will be described with reference to the flowchart of FIG.

Call information from a certain subscriber terminal 2 to a called terminal from the trunk on the domestic network 3 side (including at least the telephone number of the calling subscriber terminal; the telephone number of the called terminal, country code, The central control unit to which the area code (including an area code or the like may be included) is given first.
The accounting database 4a is accessed with the data of the telephone number described above to retrieve the balance data (step 200). Then, it is determined whether or not the balance data is 0 (step 20).
1).

If the balance data is 0, the central control unit activates a message voice trunk (not shown) and issues a voice message saying "Since the balance is 0, connection cannot be made." The call is transmitted to the calling subscriber terminal 2 (step 202), and after a predetermined time (for example, 2 seconds) elapses, a disconnection process is performed (step 203), and a series of processes activated by the calling is terminated. .

On the other hand, if the balance data is larger than 0, the central control unit activates the above-mentioned message voice trunk, and says, "The balance is XX yen. Dial the other party's telephone number." Is transmitted to the calling subscriber terminal 2 (step 204), and in response to this, the calling information addressed to the called terminal corresponding to the dialed telephone number is transmitted to the international network 5 and Then, a ringing tone is transmitted to the subscriber terminal 2 (step 205). Then, it waits for a response from the called terminal, and determines the response (step 206).

When the busy information is returned, the central control unit transmits a busy tone to the calling subscriber terminal 2 (step 207). The description of the processing at the time of disconnection for the transmission of the busy tone is omitted.

On the other hand, if an incoming call response is returned, the central control unit sets the already taken out balance data in the balance setting unit 4e (step 208).
From the regional fee database 4c, data of the basic fee per predetermined time (or the available time per basic fee) determined by the regional difference between the calling terminal and the called terminal and the call time is extracted and subtracted to the subtraction processing unit 4f. The method is set (step 209), and then the communication path between the calling terminal and the called terminal is set (sending of the ringing tone is stopped; step 21).
0), the process at the time of calling is ended.

By the above-described processing, during a period during which a call is being made, the subtraction processing unit 4f appropriately reduces the balance of the balance setting unit 4e according to the call time.

In such a call, when the trunk on the domestic network 3 or the trunk on the international network 4 detects on-hook, the central control unit is interrupted. Further, when the set balance becomes 0, the balance setting unit 4e interrupts the central control device. In the former case, the processing shown in the flowchart of FIG. 4 is executed, and in the latter case, the processing shown in the flowchart of FIG. 5 is executed.

When an on-hook interrupt occurs, the central control unit first executes a process of disconnecting the communication path (step 250).

Thereafter, the central controller updates the balance data in the accounting database 4a to the balance data set in the balance setting section 4e at that time (step 25).
1) The detailed information relating to the current call (the telephone number of the called terminal, the call time, and the amount of the current call) is stored in the charging database 4a (step 252).

The central control unit determines whether the balance data set in the balance setting unit 4e at that time is less than a predetermined amount (for example, 500 yen) (step 25).
3). If the amount is larger than the predetermined amount, the central control device immediately ends the current interrupt processing.

On the other hand, if the balance data is equal to or less than the predetermined amount, the central control unit gives the telephone number data of the calling terminal of this time to the subscriber's letter creating device 4d, and sends the subscriber's letter. Activate creation (step 25
4), the processing by the current interrupt is terminated. At this time, the subscriber's letter creation device 4d recognizes the destination of the letter based on the customer database 4b, accesses the billing database 4a, retrieves the balance data at that time and detailed information of each call, and retrieves the letter. Include in content. When the detailed information is taken out, the detailed information is deleted from the charging database 4a.

When an interruption due to the balance 0 occurs, the central controller first executes a forced disconnection process of the communication channel (step 300).

Thereafter, the central controller updates the balance data in the accounting database 4a to 0 (step 3).
01), the detailed information relating to the current call (the telephone number of the called terminal, the call duration, and the amount of the current call) is stored in the charging database 4a (step 302).

Then, the central control unit gives the telephone number data of the current calling terminal to the subscriber's letter creating device 4d to start creating the subscriber's letter (step 303). The processing by the interruption of is ended. Also at this time, the subscriber's letter creation device 4d recognizes the destination of the letter based on the customer database 4b, accesses the billing database 4a, and retrieves the balance data at that time and detailed information on each call. To be included in the letter content. When the detailed information is taken out, the detailed information is deleted from the charging database 4a.

In the case where the balance has become zero and a letter addressed to the subscriber has been created at the time of a past call under the condition of a predetermined amount or less, activation of letter creation is not performed. Is also good.

According to the telephone communication system of the first embodiment, a prepaid billing method can be applied to telephone communication using a subscriber terminal having no prepaid support structure.

Also, when a deposit form is read in at the time of deposit by the subscriber, the deposit information can be exchanged almost in real time.
And the balance in the accounting database 4a is updated.

Further, when payment information for a subscriber who is not registered in the charging database 4a arrives at the exchange 4, new registration in the charging database 4a is performed. It is not necessary for staff members to do it. Further, with this function, it is possible to considerably shorten the time from when a newly registered subscriber performs a subscription operation to when a telephone call becomes possible.

Further, since the input of the deposit information is performed using a form, it can be performed easily, and the operation other than the telephone number code and the stored amount code is printed in advance, so that the operation of completing the form is also simple. It has become something.

When the balance is small at the end of the call, a letter addressed to the subscriber is automatically created, so that the subscriber can easily recognize that the balance is small.

Further, since the subscriber is notified of the balance before the start of the call, the subscriber can estimate the possible call time.

According to the telephone communication system of the first embodiment, the following economical effects can be expected. In other words, in the case of the post-payment method, from the viewpoint of the communication service provider, there were risks such as delinquent payment and irretrievability,
In a prepayment scheme as in the embodiment, such a risk does not exist. In addition, although it is a prepayment method, in the case of the embodiment, since it is a method using a payment form without using a prepaid card, even if the payment form is dropped or stolen, the payment form before performing the payment processing is Since the deposit has not been made, the person who acquired the deposit form cannot use it, and even if it did, the acquirer would have to make the deposit himself and the original owner could be damaged. Absent.

(B) Second Embodiment Next, a second embodiment in which the subscriber communication system according to the present invention is applied to an international telephone communication system will be described in detail with reference to the drawings.

FIG. 5 is a block diagram showing the overall configuration of the telephone communication system according to the second embodiment. The same reference numerals as in FIG. 1 according to the first embodiment denote the same and corresponding parts. Is shown.

The telephone communication system 1 according to the second embodiment
Also in A, the configuration and operation related to the telephone call are the same as those of the first embodiment, and the operation mainly when the payment form is read is different from that of the first embodiment. Less than,
The differences will be briefly described.

The telephone communication system 1 according to the second embodiment
The deposit form processing device 6 in A includes an exchange-addressed transmission unit 6d for performing communication with the exchange 4, an acknowledgment reception unit 6e, and a response display unit 6f, while the exchange 4 includes an acknowledgment transmission unit 4h , Exchange information receiving unit f of the exchange 4
Is connected to the payment form processing device 6.

The payment form processing device 6 in the telephone communication system 1A of the second embodiment transmits payment information to the exchange 4 when reading the payment form. In the exchange 4, the customer database 4b confirms whether or not the subscriber exists. If the subscriber exists, a response to the presence is returned to the payment form processing device 6, and the same payment information as in the first embodiment is received. When the subscriber does not exist, the receipt form processing device 6 returns a response indicating that the subscriber does not exist.

The payment form processing device 6 causes the response display section 6f to display a response from the exchange 4 indicating the presence or absence of the corresponding subscriber. When the absence is indicated, the convenience store clerk or subscriber will confirm the telephone number and the like. Further, the payment form processing device 6 transfers the payment information to the payment information processing device 7 only after receiving a confirmation response from the exchange 4 that the corresponding subscriber exists. In the second embodiment, the transfer of the deposit information from the deposit information processing device 7 to the exchange 4 is not executed.

According to the second embodiment, effects similar to those of the first embodiment can be obtained. Further, since the subscriber who has made the payment is confirmed, erroneous payment processing can be prevented.

(C) Other Embodiments In each of the above-described embodiments, an example is described in which payment information is input by reading a bar code.
In addition, another input method may be applied. For example, a character recognition method may be applied, or a direct input method from a keyboard may be applied. When such a method is applied, the name and address of the subscriber can be included in the payment information. When the name and address of the subscriber are also included in the payment information, new registration in the customer database 4b can be performed.

Further, in each of the above-described embodiments, the description has been made assuming that all the subscribers processed by the exchange 4 are subscribers according to the prepaid system. It may be able to respond to In this case, the billing database 4a or the customer database 4b also stores a flag indicating whether or not the system is a prepaid system (whether the system is a postpaid system). Charging is performed by the method of the above-described embodiment, and if the flag is not set, charging is performed by a method similar to the conventional method. Such a flag may be automatically set at the first transfer of the deposit information. For example, the switching from the post-payment method to the pre-payment method may be automatically performed by a payment process using a predetermined payment form without notifying the telephone service provider.

Further, in each of the above-described embodiments, the case where the calling subscriber is notified of the balance before the start of the call is described. However, the calling available time determined by the balance may be notified to the calling subscriber. .

Further, in each of the above embodiments, the predetermined amount of whether to create a letter addressed to a subscriber is fixed regardless of the subscriber, but may be changed for each subscriber. It may be determined when applying for the prepayment method, or may be determined automatically, for example, by multiplying an average amount per month obtained from fees for several months by a predetermined ratio.

Further, in each of the above embodiments, the case where the exchange at the position connecting the past internal network and the international network performs the charging process is described, but the exchange at the other position performs the charging process. good. For example, the exchange that directly accommodates the subscriber terminal may perform the billing process. In this case, since the subscriber can be specified by the subscriber trunk, the prepaid system can be applied to a subscriber terminal that does not have a caller ID notification function. If the exchange directly accommodating the subscriber terminal is responsible for the billing function, the accounting database and the customer database may be provided at a location other than the exchange, and in this case, the necessary information may be provided by a common channel signaling method or the like. Is exchanged with the exchange.

Further, in each of the above embodiments, the case where charging is performed for the calling terminal has been described. However, the present invention can be applied to the case where charging is performed for the receiving terminal.

Further, in each of the above embodiments,
Although no notification is made even when the balance is close to 0, the notification may be sent to the calling subscriber or the like. For example, when a call is continued even when the balance becomes equal to or less than a predetermined value, “call will not be possible in XX seconds” may be superimposed on the call voice and transmitted to the terminal.

Further, in each of the above embodiments, the data for specifying the customer (subscriber) is a telephone number. However, customer identification data other than the telephone number may be used. For example, when a certain subscriber terminal goes off-hook, entry of customer identification data may be prompted to take in the customer identification data. When customer identification data other than a telephone number is used, the payment information naturally includes the customer identification data.

The subject system of the present invention is not limited to a telephone communication system, and the present invention can be applied to other subscriber communication systems such as the Internet.

[0079]

As described above, according to the first aspect of the present invention, a prepaid billing system can be applied to communication using a subscriber terminal having no prepaid support structure and the like, and the amount of the prepaid money can be paid. Can be immediately reflected in the communicable time.

According to the second aspect of the present invention, when the prepaid amount data for a subscriber not stored in the charging data storage means is received, the subscriber is automatically stored in the charging data storage means. Since the new registration is performed, the registration work by the operator can be eliminated, and the time until the newly registered subscriber can start communication can be shortened.

According to the third aspect of the present invention, a form in which data other than changeable data is fixedly printed, and a barcode representing the changeable data is affixed to the input for notification of the advance payment. Since the reading operation is used, the input operation and the like can be simplified.
