In order to use this mobile communication terminal, it is necessary to select one company from a plurality of mobile communication companies and conclude a subscription contract with the mobile communication company.

[0003]

However, at the time of this enrollment contract, the user's name,
It is necessary to seal the seal after filling in the address, payment method, etc. At this time, presentation of an identification card such as a driver's license or a health insurance card is required. In addition, it is necessary to wait for several hours until the result of the examination on whether or not to join is obtained.

[0004] For this reason, there has been a demand mainly for young people to use mobile communication terminals more easily. Also,
For example, a foreigner who is temporarily staying in Japan for business or sightseeing purposes has an inconvenience that he cannot use a mobile communication terminal because he does not have an address in Japan. In order to cope with such a problem, there is also a method of renting a mobile communication terminal to a temporary use applicant. That is,
A plurality of mobile communication terminals that have been purchased in advance from a mobile communication carrier on a rental contractor side and for which a subscription contract has been concluded are rented to a foreigner or the like who wants to temporarily use the terminals. In this case, since the direct subscriber is a rental company, even a person who does not have an address in Japan can use the mobile communication terminal. In addition, the rental fee is directly borne by the rental company,
Even if the actual user is unreliable in Japan, there is no disadvantage for the mobile communication carrier.

[0005] However, for rental companies,
There is always the danger that a user will go missing with a mobile communication terminal while leaving a high usage fee. In order to mitigate the risk of so-called "drop-out", it is necessary to provide a large deposit in advance, which impairs the convenience of good users. Further, even if a certain amount of security deposit is secured, there is no means to suppress the generation of a usage fee exceeding the deposit, so that the risk of defaulting cannot be completely eliminated.

The present invention has been devised in order to solve the above-mentioned conventional problems. The purpose of the present invention is to eliminate the need to seal a seal or present an identification card, and to wait for a preliminary examination.

And a talk time calculation unit for calculating the talk time by comparing the charge data and the balance data in the charge database 20
30, a call time measuring unit 34 for starting the measurement of the call time simultaneously with the line connection between the mobile phone 13 and the called terminal 32, and calculating the call charge by applying the call time to the charge system in the charge database 20. Call charge calculator 36 and balance database
The system includes at least a balance updating unit 38 for updating the balance data in 18, and a message generating unit 40 for generating a specific message signal. The message signal generated by the message generator 40 is converted into a voice through the voice synthesizer 42 and transmitted to the mobile phone 13 via the line switch 16.

In the first communication control system 10, the balance database 18 is used as balance storage means, the charge database 20 is used as charge storage means, the balance confirmation unit 26 is used as balance check means, and the call availability determination unit 28 is used as communication availability. In the determining means, the callable time calculation unit 30 is the callable time calculation means, the line switching device 16 and the line control unit 24 are the line control means, the call time measurement unit 34 is the call time measurement unit, and the call charge calculation unit 36 Corresponds to the call charge calculating means, and the balance updating section 38 corresponds to the balance updating means.

The mobile phone 13 possessed by the caller 12 and the relay mechanism
A public network 44a including a mobile communication network is interposed between the public network 44a and the public network 44a.
For example, they are connected by an ISDN line (INS 1500) 46a. When the mobile phone 13 is a mobile communication terminal using a communication satellite (for example, a mobile phone according to the “Iridium Project”), a communication satellite network is interposed in the middle. Also, a public network 44b is provided between the receiving terminal 32 and the relay mechanism 100.
The public network 44b and the line switching device 16 are also connected by, for example, an ISDN line (INS 1500) 46b.

As shown in FIG. 2, the portable telephone 13 has a plurality of push buttons 101 for inputting telephone numbers and the like.
, A liquid crystal display 102, a speaker 103 for audio output, a microphone 104 for audio input, and an antenna 105 for wireless transmission and reception. In addition, a bar code 106 indicating a telephone number (caller number) assigned to the mobile phone 13 is displayed on the back of the mobile phone 13, as shown in FIG.

FIG. 4 is a block diagram showing a part of the internal mechanism of the mobile phone 13. As shown in FIG. The mobile phone 13 includes a control unit 106 composed of a CPU that controls the entire system. The control unit 106 is connected to a ROM 107 and a RAM 108 as storage means and a wireless interface 109 for controlling wireless communication. ing. Further, a push button 101, a liquid crystal display 102, a speaker 103, a microphone 104, and the like are connected via an I / O interface (not shown). ROM10 above
In addition to the program for controlling the operation of the mobile phone 13, phone number data that is not subject to outgoing call restrictions is stored in the memory. Specifically, the relay mechanism 10
The number for connecting to 0 is stored.

When a series of numbers are input by the push button 101, the control unit 106 temporarily stores the numbers in a predetermined area in the RAM 108,
The telephone number set in the OM 107 is read. Next,
The input number and the set number are compared, and if they match, the number is output to the radio interface 109 and transmitted on the carrier from the antenna 105 to the outside. The telephone number transmitted from the antenna 105 is received by the nearest base station and connected to the relay mechanism 100 via the public network 44a. On the other hand, if the input number and the setting number do not match, a message such as "cannot transmit" is displayed on the liquid crystal display unit 102, and transmission of the input number is rejected.

That is, the mobile phone 13 is subjected to so-called outgoing call regulation so that a telephone number that can be directly called is limited to the line number of the relay mechanism 100. Relay mechanism
The phone number of 100 is set in advance by pressing
Since the button is abbreviated, it is possible to connect to the relay mechanism 100 only by pressing the “call” button. However, it is also possible to press the individual push buttons 101 to connect to the relay mechanism 100. In the ROM 107,
"110" or "119" other than the line number of the relay mechanism 100
Or the like, and it is possible to make direct calls for these emergency telephones that do not require a call charge.

Next, an actual operation method of the first communication control system 10 will be described. First, a person who wishes to use the communication control system 10 obtains a mobile phone 13 dedicated to the present system, a charger, a mobile phone set including a usage manual and the like from a system operator. The acquisition route may be obtained by hand at a service counter of an agent affiliated with the system operator, or may be obtained by a vending machine or a mail-order system as described later in detail. The mobile phone 13 is purchased by the system operator in advance from each mobile communication carrier in a lump, and a contract with a start condition is concluded with the mobile communication carrier. In this mode, the operator rents the mobile phone 13 for a fee (for example, an acquisition fee of 5,000 yen).

At this point, since the mobile phone 13 has not been opened yet, no basic charge is imposed upon subscribing to the mobile phone service. In addition, there is no danger that an unrecognized call charge will be imposed in the event of theft.

In order to start a call using the mobile phone 13, the user contacts the system operator using a public phone or a home phone, and the caller displayed on the mobile phone 13 obtained by the user. Tell the number and make an opening request. The acquisition fee includes a usage fee for the mobile phone 13 at a fixed rate. In other words, if the mobile communication service provider that supplies the mobile phone 13 is based on a fee structure of “basic charge + call charge”, the basic charge for one month and a fixed call charge must be included. Becomes In addition, if the other mobile communication service provider that supplies the mobile phone 13 is based on a fee system that does not require a basic charge and only charges the call fee, all of the usage fee shall be used for the call fee Becomes Using the balance input device 48 (keyboard or the like), the system operator who has received the notification registers the amount information corresponding to the basic charge and the call charge in the balance database 18 in a form corresponding to the caller number. As shown in FIG. 5, the balance database 18 has a table having items such as the current balance and the update date, using the caller number as a key. Further, the system operator contacts the mobile communication carrier and requests that the caller ID be opened. In response to this, the mobile communication carrier corresponds to the caller number, and thereafter makes the mobile communication service available. The time required for this opening is very short, less than 5 minutes.
At the same time, the subscription contract for the mobile phone 13 becomes effective, and the application of the basic fee starts.

As described above, the mobile phone 13 can be obtained by simply exchanging the price without requiring the seal stamping or presentation of the identification card, and without waiting for the result of the preliminary examination. It can be used by a very simple procedure of telephone contact. After receiving a message from the user as described above, for the first time, instead of the system operator entering and registering the caller number and balance data in the balance database 18, the system operator stores the caller number and balance data in advance. The information may be input, and after receiving the notification, the registration may be fixed using the input device 48 such as a mouse or a keyboard.

Since the call fee included in the above acquisition fee is relatively low (for example, a local call can be made for about 10 minutes), in order to secure a sufficient call time and call distance,
It is necessary to pay a new deposit and replenish the balance information to the balance database 18 of the user. That is, a transfer sheet (not shown) attached to the mobile phone set with a fixed number of sheets,
After filling in the amount to be paid (for example, 10,000 yen), bring it to a financial institution or convenience store and give it out together with cash. Then, a receipt stamp of a financial institution or a convenience store is pushed on the copy slip of the transfer paper, and this is transmitted to the operator of the communication control system 10 by facsimile.

In this copy, the caller number of the mobile phone 13 is preliminarily written in a bar code or characters, and the system operator uses the balance input device 48 (bar code reader, keyboard, etc.) Enter the prepaid amount corresponding to the number. This input data is stored in the balance database 18 via the balance update unit 38. Also, your name,
A user who wishes to register an address, contact information, etc., writes those items in this copy. The system operator can use F
By registering the information described in the copy sent by AX in the balance database or other databases, the information can be referred to when providing various services at a later date. It is needless to say that when the user requests cancellation, the above-mentioned deposit is settled and the balance is returned.

If the computer constituting the information management system of the financial institution or the convenience store is connected to the computer constituting the communication control system 10 online, the above procedure can be further simplified. That is, when data such as a caller ID and a prepaid amount is input from a terminal of a financial institution or a convenience store, the data is automatically registered in the balance database 18 via the balance update unit 38 of the communication control system 10. This saves the user from facsimile sending a copy of the copy to the system operator and saving the system operator from inputting data. In this case, a terminal of a financial institution or a convenience store functions as the balance input device 48. As shown in FIG. 3, a bar code corresponding to the caller number is displayed on the back of the mobile phone 13 in advance, and the bar code is read by a bar code reader connected to a terminal of a financial institution or a convenience store. This can save labor for inputting the caller ID and eliminate erroneous input.

After the sufficient prepaid balance information is registered in the balance database 18 as described above, and the opening work by the mobile communication carrier is completed, the user makes a “call” of the mobile phone 13.
I press the button. As a result, the mobile phone 13 is immediately connected to the relay mechanism 100, and a communication path is established.

As shown in the flowchart of FIG. 6, the line control unit 24 recognizes the caller number of the mobile phone 13 (S10) and sends it to the balance check unit 26. The caller ID data is transferred from an exchange belonging to the public network 44a on the caller side, and uses, for example, a caller ID notification service of NTT. The balance confirmation unit 26 searches the balance database 18 using the sender number as a keyword, and confirms the current balance of the deposit of the sender (S12). The balance data confirmed here is sent to the call availability determination unit 28. In the call availability determination unit 28,
It is determined whether or not the balance is sufficient to permit a call (S14). That is, if the balance is less than a preset amount (for example, 100 yen), the communication control unit determines that "call is not possible" and sends the determination result to the line control unit 24 and the message generation unit 40.

The message generator 40 generates a message signal indicating that the connection is not possible because the balance is insufficient, and outputs the message signal to the voice synthesizer 42. Upon receiving the message, the voice synthesizer 42 synthesizes a voice corresponding to the message signal, and transmits the synthesized voice to the mobile phone 13 via the line switching device 16 (S16). The message generation unit 40 generates a message signal corresponding to a foreign language such as Chinese, Korean, or English, in addition to Japanese, and converts this into a language of each country by a voice synthesizer 42, and sequentially outputs the message to a mobile phone.
Preferably, it is configured to transmit to 13. Line control unit 24
Disconnects the communication path with the mobile phone 13 when the transmission of the voice message is completed.

On the other hand, if the balance of the prepaid money is equal to or more than a certain amount, the call permission / non-permission determining unit 28 determines that the call is possible and sends the result of the determination to the line control unit 24 and the message generation unit 40. I do. In the message generator 40,
For example, a message signal having a content such as "You can talk for XX yen. Please enter the telephone number of the other party" is generated and output to the speech synthesizer 42. Voice synthesizer 42
The message vocalized into each language is transmitted to the mobile phone 13 via the line switching device 16 (S18).

When prompted by the message, the caller 12 inputs the telephone number of the destination using the push button 101, and the available call time calculator 30 recognizes the area code (area code) (S20). Using this as a keyword, the charge database 20 is searched, and the balance is applied to the charge system of the mobile phone 13 to calculate a talkable time (S2).
2). That is, the charge database 20 stores the charge system (unit price information) of the call charges classified by area code and time zone for each mobile communication carrier. Therefore,
By applying the area code and the current date and time information to the fee structure of one mobile communication carrier specified based on the caller ID, the unit price of the call fee is determined, and the balance is divided by this unit price. The specific callable time is calculated.

When the possible call time is calculated as described above, the result is transmitted to the line controller 24 and the message generator 40.
Sent to In the message generation unit 40, for example, “XX
Minutes are available. A message signal such as "I will connect now" is generated and output to the voice synthesizer 42, the corresponding voice is synthesized by the voice synthesizer 42, and transmitted to the mobile phone 13 via the line switching device 16. Is done. Thereafter, the line control unit 24 generates a dial signal corresponding to the input telephone number of the other party, and sends the dial signal to the public network 44b via the line switching device 16. Then, the receiving terminal 32
The line switching device 16 connects the mobile telephone 13 and the line of the receiving terminal 32 at the point in time when the communication path is established between
Four). At the same time, the call time measuring unit 34 starts measuring the call time (S26).

The line control unit 24 constantly monitors the measurement result from the call time measuring unit 34, and determines whether or not the callable time has elapsed (S28). Then, when the talkable time has elapsed, a control signal is immediately output to the line switching device 16,
The line between the mobile phone 13 and the receiving terminal 32 is forcibly disconnected (S30). The measurement result in the call time measurement unit 34, that is, the call time, is transmitted from the call time measurement unit 34 to the call charge calculation unit.
Output to 36. The call charge calculator 36 calculates the actual call charge based on the call time and the charge system stored in the charge database 20 (S32), and outputs this to the balance update unit 38. The balance update unit 38 is a balance database
18 minus the above call charges (ie, 0
Is updated and registered as new balance information (S34).

When the call is terminated within the talkable time, that is, when a spontaneous line disconnection is performed between the mobile phone 13 and the receiving terminal 32, the line control unit 24 outputs the disconnection signal (end signal). Talk signal) is detected (S36), and the talk time measuring unit
The measurement of the talk time in 34 is stopped. The call time measured by the call time measurement unit 34 is
Is output to the call charge calculation unit 36. The call charge calculation unit 36 calculates an actual call charge based on the call time and the charge system stored in the charge database 20 (S3).
2), which is output to the balance updating unit 38. Balance update unit 38
Updates and registers the amount obtained by subtracting the call charge from the balance in the balance database 18 as new balance information (S34). Instead of calculating the call charge collectively after the end of the call as described above, the call charge calculation unit 36 accumulates the call charge simultaneously with the start of the call based on the output from the call time measurement unit 34 and the above-mentioned charge system. It may be operated so that

Note that, instead of suddenly disconnecting the line when the talkable time elapses as described above (S30), a message such as "Talk time will end in XX minutes" is generated by the message generation unit. It may be configured to be created by the voice synthesizing device 40 and the voice synthesizing device 42 and transmitted to the mobile phone 13 via the line switching device 16. Or, instead of disconnecting the line,
The call charges exceeding the balance are recorded as a negative balance within a certain limit in the balance database 18, and the next time the balance is replenished, it is operated flexibly so that the previous negative balance is settled. It is also possible.

The telephone charges (including the basic charges) incurred by using the first communication control system 10 will be billed at a later date from each mobile communication carrier to the system operator. The system operator applies the deposit of the sender 12 transferred to his or her bank account through a financial institution or a convenience store to the payment.

The system operator may operate to collect a rental (lease) fee from the balance at a fixed rate every time the caller 12 uses the communication control system 10. For example, a fixed rental fee is added to the charge system in the charge database 20 from the beginning, and when calculating the callable time and calculating the call charge based on the added charge, the reduced amount of the balance can be calculated. The difference from the payment to the mobile communication carrier can be secured as a rental fee.
Alternatively, it can be operated such that a predetermined rental fee is deducted from the balance on a monthly basis.

In the balance database 18 or in another independent database, for each caller number, history data such as date and time of call, called party number, call time, call charge, balance replenishment date, replenishment amount, etc. Is stored. Then, the history data can be totaled for each fixed period (for example, every month), and a usage statement in which necessary data items are printed out can be issued to the sender 12 whose address and name are registered.

By using the communication control system 10, the sender 12 can enjoy the following advantages. With a very simple procedure, the mobile phone 13 can be used. That is, since the mobile phone 13 is a form that is lent to the mobile phone by the system operator and purchased by the system operator, a subscription contract that requires the stamping of a seal and the presentation of an ID card is not required. End users are not subject to such procedures.
The end user only has to pay the amount to be used and the basic fee in advance. Calls can be made within the range of the amount set in advance by the user.
It is possible to prevent an unexpected expense from being increased due to excessive use of 13. For this reason, for example, when the child is given the mobile phone 13, the parent can control the call charge. In addition, since there is no incoming call restriction on the mobile phone 13, all calls made by the third party to the mobile phone 13 can be received.

The communication control system 10 also has the following advantages on the mobile communication carrier side. It is only necessary to conclude a contract with the operator of the communication control system 10, and there is no need to conclude a subscription contract with the user of the mobile phone 13 individually. Therefore, the cost of managing a large number of end users can be significantly reduced. Collection of the call charge is performed by the system operator, so no charge is charged and the service can be provided with peace of mind.

As described above, since the use of the communication control system 10 is expected to significantly reduce costs on the mobile communication carrier side, it is also possible to reduce the call charges for users of this system. It becomes possible. Also, in the above description, the charge system of “basic charge + pay-as-you-go communication charge” is mainly described as the charge of the mobile phone 13, but a charge system in which only the call charge is charged without the basic charge is adopted. You may.

Further, the communication control system 10 can minimize the risk on the system operator side. In other words, in this communication control system 10, the call made directly from the mobile phone 13 of the caller 12 is limited to the relay mechanism 100 except for a free emergency call such as 110 or 119. Is the relay mechanism 1
It is not possible to make a long-distance call or a long-time call without passing through 00. Therefore, there is no danger that a request exceeding the prepaid balance will be delivered from the mobile communication carrier at a later date. If the call availability determination unit 28 operates to determine whether or not a call can be made after subtracting the basic fee for the next month from the current balance, it is possible to avoid the danger that the basic fee for the next month will be unpaid. .

By using the communication control system 10, for example, the following usage forms can be realized. First,
Since the troublesome procedure at the start of use is unnecessary, the mobile phone 13 can be supplied by a vending machine. This vending machine is installed near the arrival gate at the airport. Foreigners who visit Japan temporarily for sightseeing or business purposes,
The vending machine obtains a set of the mobile phone 13 and a charger in exchange for, for example, 5,000 yen. in this case,
The battery of the mobile phone 13 is charged in advance so that a call can be made for a certain period of time. During the above set,
Instruction manuals in major foreign languages such as English, German, French, Chinese, Korean, and Spanish are enclosed. The foreigner who has obtained the mobile phone 13 contacts the system operator from a public telephone in the airport in accordance with the usage manual, gives a caller ID, and makes an opening request. In addition, a prepaid money is paid at a stand or a bank in the airport, and a copy of the receipt stamp with the receipt stamp is transmitted by fax to the system operator. As a result, even a foreigner who does not have an address in Japan can use the mobile phone 13 while staying in Japan. When returning to Japan, the mobile phone 13 is returned in exchange for a certain amount of cash (for example, a refund of 2,000 yen) at the service counter of an agency affiliated with the system operator, and the balance is settled.

The relay mechanism 100 of the communication control system 10
Is mainly configured with a computer system such as a mainframe, a workstation, and a personal computer (hereinafter, referred to as a “personal computer”). FIG. 7 shows an example in which the relay mechanism 100 is configured around a personal computer.
CPU (Central Processing Unit) 50, RAM 54, ROM 56 connected to CPU 50 via system bus 52, timer
58, a hard disk device 60, a line switching device 16, a display 62, a voice synthesis device 42, and an input device 64 such as a keyboard. An application program and an OS for operating the communication control system 10 are stored in the hard disk device 60. By activating these software, the CPU 50 causes the above-described line control unit 24, balance checking unit 26, various functional components such as a call permission / non-permission determining unit 28 are provided. Further, the balance database 18 and the charge database 20 described above are stored in the hard disk device 60. By providing the current date and time data to the communication control system 10 by the timer 58, the calculation of the talkable time and the measurement of the talk time are realized.

The above hardware configuration is merely an example, and the present invention is not limited to this. For example, a plurality of personal computers are connected to a LAN (Local area n
The communication control system 10 can be realized by distributed processing. In this case, each functional component to be performed by the communication control system 10 is allocated to a plurality of personal computers and the like. As an example, the line switching device 16 is connected to the personal computer A, and functions as the line control unit 24 and the call time measuring unit 34 are provided.
The balance database 18 is connected to the personal computer B and functions as a balance confirmation unit 26, a call availability determination unit 28, and a balance update unit 38 are provided. The charge database 20 is connected to the personal computer C, and a talk time calculation unit 30, a call Having a function as the fee calculation unit 36 corresponds to this. Pricing database
20 and the functional components related thereto can be realized by a computer system on the mobile communication carrier side that provides the mobile phone 13 in particular. When the system is configured by mixing mobile phones 13 provided by a plurality of mobile communication carriers, the fee structure is different for each mobile communication carrier, and there is a possibility that the fee is frequently revised. Therefore, that is more convenient. The balance database 18 and the charge database 20 do not necessarily need to be configured by one storage device, and the balance database 18 and the charge database 20 may be configured by combining a plurality of storage devices.

When using this communication control system 10,
Since a call charge from the mobile phone 13 to the relay mechanism 100 of the present system 10 is charged to the caller 12, it is desirable to provide as many access points as possible in various parts of Japan. On the other hand, it is suitable that the balance database 18 and the charge database 20 be centrally managed in the center. Therefore, access points equipped with the line switching device 16 and the functional components necessary for line control are arranged in various places in Japan, and the balance database 18 and the charge database 20 are arranged in the center, so that the access points in each area and the central The present system can also be realized by networking through a dedicated line.

The communication control system 10 is also applicable to making an international call from the mobile phone 13. That is,
The toll database 20 also stores in advance toll-based toll system information for each of a plurality of international telecommunications carriers. FIG.
Indicates a part of the tariff structure of an international carrier. Then, based on the telephone number of the called party 14 input from the mobile phone 13, the international communication carrier selected by the user is specified. For example, if the prefix of the input telephone number includes “001” as the international prefix number, international telephone number (KDD) is selected as the international communication carrier and the available call time calculation unit 30 By recognizing and applying the balance data corresponding to the caller ID recorded in the balance database 20 to the KDD charge table stored in the charge database 20, the talkable time is calculated.
The call charge calculating unit 36 also calculates the actual call charges by applying the call time output from the call time measuring unit 34 to the KDD charge table.

Alternatively, a configuration is adopted in which, from among a plurality of international telecommunications carriers, a telecommunications carrier with the lowest call charge at the current time is automatically selected, and an international call through the international telecommunications carrier is realized. You can also. FIG.
FIG. 10 is a block diagram showing a second communication control system 70 as an example, and FIG. 10 is a flowchart showing an operation method thereof. The same parts as those in the first communication control system 10 and its operation method are denoted by the same reference numerals, and description thereof will be omitted.

The second communication control system 70 includes a portable telephone 13 carried by a caller, a KDD and a Japan Telecom (J.
T), intervening between exchanges α to γ of a plurality of international telecommunications carriers A to C such as international digital communication (IDC),
There is provided a relay mechanism 110 that performs line connection and line disconnection between the call receiver 13 and the overseas called party 14 via the international communication carriers A to C, billing processing of a call charge, and the like. In the central portion 22 of the second communication control system, there is provided an optimum communication carrier specifying section 72 as an optimum communication carrier specifying means. Also,
The toll database 20 stores toll-based toll system information for each of the international carriers A to C.

Next, an actual operation method of the second communication control system 70 will be described. The caller 12 whose prepaid balance information has been registered in the balance database 18 and which has completed the opening work by the mobile communication carrier, first presses the "call" button. The call button includes the relay mechanism 11 of the above system.
Since the telephone number for connecting to 0 is registered in advance in abbreviated form, the mobile phone 13 is immediately connected to the relay mechanism 110, and the communication path is established.

Then, as shown in the flowchart of FIG. 10, the balance confirmation unit 26 confirms the balance of the caller 12 (S12), and the call availability determination unit 28 completes the determination of the call availability (S14, S18). After a dial signal indicating the country code, area code (area code), local area code and subscriber number is transmitted from the caller 12 to the callee 14 (S2
0), the most advantageous international communication carrier at the present time is selected in the optimum communication carrier specifying unit 72 (S21). That is, since the fee database 20 stores information in which the fee system for each of the international carriers A to C is made into a database as described above, if the country or region of the called party 14 is specified, It is possible to determine the lowest international communication carrier (for example, the international communication carrier A) based on the current date and time data. Next, the talkable time calculation unit 30 calculates the talkable time by applying the balance data to the fee system of the international communication carrier A selected above (S22).

The line control unit 24 generates a dial signal corresponding to the selected international prefix number of the international communication carrier A + the country code of the called party + the area code + the local area code + the subscriber number, The signal is output to the public network 44b via the line switching device 16. When a communication path is established with the called terminal 32 via the exchange α of the international communication carrier A, the line switching device 16 connects the mobile phone 13 to the line of the called terminal 32. (S24). Thereafter, the same steps as in the first communication control system 10 are performed. Note that, depending on the time zone and the partner country, the international telecommunications carriers B and C may be more advantageous in terms of price. In this case, the most advantageous other communication carrier at the present time is selected by the optimum communication carrier selection unit 72, and the call through the exchange of the corresponding carrier is realized.

The first communication control system 10 according to the present invention
However, it is also possible to introduce a settlement method using a credit card. FIG. 11 and FIG. 12 show an example thereof, and the following configuration is added to the first communication control system 10. That is, when a connection is made from the mobile phone 13, a credit card database 74 as a credit card storage unit for storing information on the credit card of the caller 12 in association with the caller number of the mobile phone 13. The credit card database 74 and the balance database 18 are searched using the user number as a key,
A payment type identification unit 76 as a payment type identification unit for identifying whether the caller 12 is a credit card payment selector or a prepaid payment selector, and, if the caller 12 is a credit card payment selector, the credit The card information is transmitted to the computer systems X to Z managed by each credit card company via the external system communication unit 78 which performs an interface function with the external system, and
Credit inquiry unit 80 as a credit inquiry means for performing 12 credit inquiries
And the communication charge calculated after the call is terminated, via the external system communication unit 78.
And a call fee billing unit 82 as a call fee billing means for transmitting to the user.

In addition to these, the line switching device 16,
Charge database 20, voice synthesizer 42, line controller 24,
Balance confirmation unit 26, call availability determination unit 28, call availability time calculation unit
30, call time measurement unit 34, call charge calculation unit 36, balance update unit 3
8. Although a message generation unit 40 and the like are naturally provided, FIG. 11 mainly illustrates a portion related to credit card settlement.

Next, an operation method of credit card settlement will be described. First, a person who wishes to make a payment by a credit card gives an intention to that effect to the system operator and declares information (such as a card company name and a card number) on the credit card owned by the person. On the system operator side, such information is stored in the credit card database 74 in association with the caller number.

When the caller 12 is connected to the relay mechanism 100 of the first communication control system 10 via the mobile phone 13, the line controller 24 controls the mobile phone as shown in the flowchart of FIG. Recognize 13 caller IDs (S10),
This is transmitted to the settlement type identification unit 76. Payment type identification unit 76
Then, the credit card database 74 is searched using the caller number as a keyword, and it is confirmed whether or not the caller 12 is registered as a credit card payment selector (S40). If registered as a credit card payment selector, the credit card information (code specifying the company name, credit card number, etc.) of the sender 12 is transmitted to the credit inquiry unit 80.

The credit inquiry unit 80 specifies one credit card company from the credit card information,
Data such as a credit card number is transmitted to a computer system (for example, X) managed by the credit card company via the external system communication unit 78, and an inquiry is made as to the credit status of the sender (S42). The inquiry result from the computer system X is transmitted to the call availability determination unit 28 via the external system communication unit 78 and the credit inquiry unit 80. When the inquiry result is affirmative, the call permission / non-permission determining unit 28 determines that the call using the present system is permitted (S44). Then, a message to the effect that the call can be made and a prompt to input the telephone number of the other party are transmitted to the mobile phone 13 (S46). On the other hand, if the inquiry result is negative, it is determined that the call cannot be made (S44), a message to that effect is transmitted to the mobile phone 13 (S48), and the line is disconnected.

When the caller 12 inputs the telephone number of the other party, the line controller 24 recognizes this (S52), generates a dial signal corresponding to the telephone number of the other party, and
The data is transmitted to the public network 44b via the communication network 16b. Then, when a communication path is established with the called terminal 32, the line switching device
16 connects the mobile phone 13 of the caller 12 to the line of the called terminal 32 (S53). At the same time, the call time measurement unit 34 starts measuring the call time (S54).

When the call ends, that is, when the mobile phone 13
If a spontaneous line disconnection has been performed between the communication terminal and the called terminal 32, the line control unit 24 detects a disconnection signal (end signal) (S56), and the call time in the call time measurement unit 34 Measurement is stopped. The call time measured by the call time measurement unit 34 is output from the call time measurement unit 34 to the call charge calculation unit 36. The call charge calculating unit 36 calculates an actual call charge based on the call time and the charge system stored in the charge database 20 (S58), and outputs this to the call charge requesting unit 82. The call charge requesting unit 82 transmits the data corresponding to the call charge to the computer system X of the credit card company via the external system communication unit 78 (S60), and requests the settlement of the call charge by the credit card.

It is to be noted that an appropriate limit is set in accordance with the creditworthiness of the caller 12, and the available time is calculated based on the limit, and the line is forcibly disconnected when the available time elapses. It can also be operated as follows.

When the payment type identification unit 76 searches the credit card database 74 and determines that the caller ID is not registered as a credit card payment, the determination result is sent to the balance confirmation unit 26. (S40). In the balance confirmation unit 26, the balance database
18 to check whether the caller is a prepaid settlement elector (whether there is a registration of a prepaid balance corresponding to the caller number), and if there is a registration, the prepaid balance is checked. Confirmation (S62). After that, the process for the prepaid settlement selector proceeds sequentially according to the steps shown in the flowchart of FIG.

In the above description, an example is shown in which the credit card settlement chooser and the prepaid settlement chooser are alternatively divided. However, the same sender 12 is selected by the credit card settlement chooser and the prepaid settlement choice. You can also register with both. In this case, after a communication path between the mobile phone 13 and the relay mechanism 100 is established, based on a specific dial signal input from the mobile phone 13, each time a call is made, a credit card payment or a prepaid payment is performed. Can be freely selected (for example, “# 1” for prepaid payment, and “# 2” for credit payment). As a result,
Normally, while prepaid payment is mainly used, when the balance temporarily runs short, it is possible to switch to credit card payment and make a call.

Alternatively, even a person who is not registered in the credit card database 74 in advance as a credit card payment selector can be operated so as to permit credit card payment by a certain number input operation.
For example, if the caller 12 whose name and address are registered in advance in the balance database 18 in correspondence with the caller number needs to make a credit card payment in a hurry, a specific dial signal ("# 3" etc.) ) To indicate that he / she wants extra credit card payment. Then, in accordance with the voice guidance, the user inputs the identification number assigned to the credit card company to which he / she joins and his / her card number. Receiving this, the settlement type identification unit 76 sends the data related to the name and address of the sender, the credit card company and the credit card number to the credit inquiry unit 80, and thereafter follows the same procedure as described above for the credit card. Settlement is performed.

In the above, the first communication control system
Although an example in which a credit card payment function is added to 10 has been described, it is naturally possible to add a credit card payment function to the second communication control system 70.

[0073]

According to the communication control system and the communication control method according to the present invention, a caller having a mobile communication terminal, except for a free emergency call such as 110 or 119, goes through the relay mechanism of this system. Calls that cannot be made cannot be made, and calls are permitted only when the prepaid balance is equal to or more than a certain amount. Therefore, there is no danger of call charges being lost. For this reason, it is not necessary to provide a large security deposit or present an ID card in advance, and the applicant can use the mobile communication terminal with a very simple procedure.
