Description

  The present invention relates to a privacy telephone exchange system.

  For example, when a user who uses a telephone terminal (fixed telephone, mobile phone) wants to contact a specific person, the other party is notified of the telephone number of his / her telephone terminal. However, the user may not want the other party to know the telephone number (privacy number) of his / her telephone terminal depending on the party with whom he / she contacts. If the privacy number is known to the other party, for example, an incoming call from a party whose identity is not well understood or an incoming call from a person who no longer wants to contact must be received.

  If you do not want to receive incoming calls from a specific person on your phone terminal, register this specific person's telephone number, and the registered telephone number and the telephone number registered by the notified sender There is known a system for rejecting an incoming call when the number matches.

Further, in Patent Document 1, a destination address (telephone number or e-mail address) is notified only to a specific communication terminal based on a request on the receiving side, and the use of the address is limited on the specific communication terminal. Technology is disclosed. As a result, the receiving side is limited to only incoming calls from a specific communication terminal, and the address of the receiving side can be concealed on the specific communication terminal.
JP 2003-143658 A

  However, in a system in which an incoming call is rejected when the telephone number registered in advance matches the telephone number of the caller to be notified, it is necessary to register all telephone numbers to be rejected. However, it is unrealistic to register all telephone numbers that reject incoming calls. In addition, when the privacy number is changed due to a given circumstance, it is necessary to register all telephone numbers to be rejected again.

  Further, the technique described in Patent Document 1 requires a change in the program of the mobile phone, which not only increases the cost for notifying the destination address but also prevents the use of an existing communication terminal. There is. Further, when the privacy number is changed, it becomes necessary to notify the other party of the destination address again. Therefore, re-notification of the destination address becomes complicated. In addition, there is no choice but to receive incoming calls from third parties before re-notification.

  The present invention has been made in view of the technical problems as described above, and a first object of the present invention is a privacy telephone that can conceal a privacy number from the other party using an existing communication terminal. To provide an exchange system.

  In the present invention, registration information in which a privacy number for specifying a privacy telephone terminal is associated with a temporary allocation number is held in the privacy telephone exchange system. In the privacy telephone exchange system, when an incoming call is received from a calling terminal, a temporary allocation number is received from the calling terminal. Then, referring to the registered information, the calling means makes a call to the privacy telephone terminal using the privacy number associated with the temporary allocation number. Therefore, it is possible to establish a call between the privacy telephone terminal and the calling terminal only by notifying the calling terminal of the public number assigned to the privacy telephone exchange system and the temporary allocation number.

  As a result, it is not necessary to inform the calling terminal of the privacy number of the privacy telephone terminal, and the privacy number can be kept secret from the other party using the existing telephone terminal. In addition, since the user of the privacy telephone terminal only needs to notify the public number and the temporary allocation number only to the person who wants to receive the incoming call, it can receive the incoming call of only a specific person. In addition, even if the privacy number is changed, it is only necessary to change the registration contents of the registration information, so that it is possible to reliably receive an incoming call from the calling terminal as before the change of the privacy number. That is, it is possible to avoid a situation in which an incoming call is temporarily received from an unknown party accompanying the change of the privacy number.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below do not unduly limit the contents of the present invention described in the claims. Also, not all of the configurations described below are essential constituent requirements of the present invention.

1. First Embodiment A privacy telephone exchange system performs exchange connection of a transmission path between a caller terminal and a callee telephone terminal connected to a public network (subscriber network or mobile communication network). The calling telephone terminal is an existing telephone terminal that can notify the telephone number of the telephone terminal. The called telephone terminal (privacy telephone terminal) is also an existing telephone terminal. In the privacy telephone exchange system, the transmission line exchange connection between the telephone terminal (transmission terminal) on the transmission side and the privacy telephone terminal can be performed in a state where the telephone number of the privacy telephone terminal is concealed. Hereinafter, the telephone number of the receiving terminal that the user of the receiving terminal desires to keep confidential is referred to as a privacy number.

  FIG. 1 shows an outline of the configuration of the privacy telephone exchange system in the first embodiment.

  The privacy telephone exchange system 10 includes a registration information storage unit (storage unit) 12, a receiver (first receiving unit) 14, a numeric receiver (second receiving unit) 16, and a transmitter (transmitting unit) 18. And a switch unit (exchange connection means) 20. These units are controlled by the control unit 22.

  The registration information storage unit 12 stores registration information. The function of the registration information storage unit 12 is realized by hardware such as a ROM (Read Only Memory), a RAM (Random Access Memory), or a hard disk.

  FIG. 2 shows an example of registration information. In the registration information, the privacy number assigned to the privacy telephone terminal is associated with the temporary assignment number. FIG. 2 shows an example in which the privacy number assigned to the privacy telephone terminal is “090-9987-5432” and the temporary assignment number is “1234”. The privacy number is a number uniquely assigned in the public network to identify the privacy telephone terminal. The temporary assignment number is a number uniquely assigned in the privacy telephone exchange system 10.

  In FIG. 1, the privacy telephone exchange system 10 is assigned a public number unique to the public network (for example, 03-1234-5678). The receiver 14 connected to the public network receives an incoming call from a transmission terminal whose destination is a public number via a public network exchange. The function of the receiver 14 is realized by a subscriber circuit, for example.

  The numeric receiver 16 has a function of a signal transmission / reception circuit that receives numeric information from the transmitting terminal. The numeric receiver 16 receives a temporary allocation number notified from the transmitting terminal on condition that the receiver 14 receives an incoming call from the transmitting terminal.

  When the temporary allocation number is received by the number receiver 16, the control unit 22 reads the registration information stored in the registration information storage unit 12 as shown in FIG. And the control part 22 searches registration information by using the temporary allocation number received by the number receiver 16 as a search key, and specifies the privacy number matched with this temporary allocation number.

  The transmitter 18 performs a call to the privacy telephone terminal using the privacy number specified by the control unit 22. The function of the transmitter 18 is realized by a subscriber circuit, for example.

  The switch unit 20 has a function as a speech path switch realized by a time division switch. The switch unit 20 performs exchange connection of the transmission path between the privacy telephone terminal that responds to the transmission by the transmitter 18 and the transmission terminal.

  The control unit 22 includes, for example, a CPU (Central Processing Unit) and a memory, and controls each unit of the privacy telephone exchange system 10 according to a program stored in the memory.

  FIG. 3 shows a flowchart of an operation example of the privacy telephone exchange system in the first embodiment. For example, a memory (not shown) of the control unit 22 stores a program for controlling each unit of the privacy telephone exchange system according to the following flow. Here, it is assumed that the registration information shown in FIG. 2 is already stored in the registration information storage unit 12.

  First, the receiver 14 monitors whether there is an incoming call from a calling terminal whose destination is a public number (step S10: N). Then, when the receiver 14 detects an incoming call from a calling terminal whose destination is a public number and accepts this (step S10: Y), the number receiver 16 notifies the calling terminal of a temporary allocation number. Request and accept a temporary allocation number from the calling terminal (step S11). More specifically, the numeric receiver 16 transmits a given signal to the calling terminal and requests transmission of a temporary allocation number. And the temporary allocation number transmitted from the transmission terminal in response to this request is received.

  Next, the control unit 22 reads the registration information stored in the registration information storage unit 12 (step S12). Then, the control unit 22 searches the registration information using the temporary assignment number received by the number receiver 16 as a search key, and specifies the privacy number associated with the temporary assignment number (step S13).

  Here, when the registration information includes a privacy number associated with the temporary allocation number accepted in step S11 (step S14: Y), the transmitter 18 uses this privacy number to make a call to a privacy telephone terminal. Is performed (step S15). Then, waiting for a response from the privacy telephone terminal, and when there is a response (step S16: Y), the switch unit 20 sets the transmission path between the privacy telephone terminal that responds to the transmission by the transmitter 18 and the transmission terminal. Exchange connection is performed (step S17).

  On the other hand, in step S14, when there is no privacy number associated with the temporary allocation number accepted in step S11 (step S14: N), or in step S16, there is no response from the privacy telephone terminal (step S16: N) The transmitter 18 stops the transmission operation to the privacy terminal, and the receiver 14 disconnects the communication path set by the incoming call from the transmission terminal (step S18).

  Such a privacy telephone exchange system is applied to a communication system having the following configuration.

  FIG. 4 shows an outline of a configuration example of a communication system to which the privacy telephone exchange system according to the first embodiment is applied.

  In this communication system, a privacy telephone exchange system 10, a calling terminal 40, and a privacy telephone terminal 50 are connected to a public network 30. In order to specify the privacy telephone exchange system 10 in the public network, a public number (for example, 03-1234-5678) that is a unique number in the public network is assigned to the privacy telephone exchange system 10. In addition, in order to specify the privacy telephone terminal 50 in the public network, the privacy telephone terminal 50 is assigned a privacy number (for example, 090-9876-5432) which is a unique number in the public network.

  According to the first embodiment, it is possible to make a call from the calling terminal 40 to the privacy phone terminal 50 while keeping the privacy number of the privacy phone terminal 50 secret. Therefore, the user of the privacy telephone terminal 50 registers the registration information shown in FIG. 2 in the privacy telephone exchange system 10.

  FIG. 5 shows an outline of a registration sequence of registration information in the communication system of FIG.

  First, the user of the privacy telephone terminal 50 uses the privacy telephone terminal 50 or a given user terminal (communication terminal in a broad sense) (for example, a personal computer) to the privacy telephone exchange system 10 via the public network or the Internet. Request registration of registration information. Then, the user of the privacy telephone terminal 50 notifies the privacy telephone exchange system 10 of the privacy number (090-9987-5432) (R1).

  The privacy telephone exchange system 10 assigns a temporary assignment number (1234) to the notified privacy number (R2) and generates registration information (R3). The generated registration information is held in the privacy telephone exchange system 10.

  The privacy telephone exchange system 10 notifies the privacy telephone terminal 50 (or its user) of the temporary assignment number (1234) assigned to the notified privacy number (090-9987-5432) (R4).

  The user of the privacy telephone terminal 50 notifies the public telephone number (03-1234-5678) of the privacy telephone exchange system and the temporary allocation number (1234) only to the other party that he / she wants to receive the incoming call.

  Then, by making a call from the calling terminal using the public number (03-1234-5678) and the temporary allocation number (1234), the privacy number is not known to the user of the calling terminal, but from a specific person. Only incoming calls can be accepted.

  Hereinafter, the outline of the operation of the communication system shown in FIG. 4 will be described with reference to the sequence shown in FIG.

  FIG. 6 shows an outline of the exchange connection sequence in the communication system of FIG.

  The user of the calling terminal 40 notified of the public number (03-1234-5678) and the temporary allocation number (1234) from the user of the privacy telephone terminal 50 uses the calling terminal 40 to change the privacy according to the public number. A call is made to the telephone exchange system 10 (T1). In the public network 30, the outgoing call is relayed by one or more exchanges and connected to the privacy telephone exchange system 10.

  In response to this call, the privacy telephone exchange system 10 requests the caller terminal to notify the temporary allocation number (T2). When the temporary allocation number (1234) is notified from the calling terminal 40 (T3), the privacy telephone exchange system 10 searches for registration information (T4), and the privacy associated with the temporary allocation number (1234). Specify the number (090-9876-5432).

  Then, the privacy telephone exchange system 10 makes a call to the privacy telephone terminal 50 using this privacy number (090-9987-5432) (T5). In the public network 30, this outgoing call is relayed by one or more exchanges and connected to the privacy telephone terminal 50.

  When the privacy telephone terminal 50 responds to this call (T6), the privacy telephone switching system 10 exchanges the transmission path between the calling terminal 40 and the privacy telephone terminal 50 (connected to the receiver 14). The transmission line and the transmission line connected to the transmitter 18 are connected (T7) to establish a call between the calling terminal 40 and the privacy telephone terminal 50 (T8).

  As described above, according to the first embodiment, the privacy telephone terminal 50 can accept only incoming calls from the person who has notified the public number and the temporary allocation number, and the privacy number of the privacy telephone terminal 50 is concealed. I can keep it. In addition, the call terminal 40 and the privacy telephone terminal 50 can use existing telephone terminals, and can construct a system at low cost.

  Furthermore, even when the privacy number is changed due to a given situation, only the registration content of the registration information needs to be changed. Therefore, even when the privacy number is changed, it is possible to continue the state of accepting only incoming calls from the person who has notified the public number and the temporary allocation number.

  In FIG. 4, the configuration in which the privacy telephone exchange system 10 is connected to the public network 30 has been described. However, the privacy telephone exchange system 10 may be replaced with one of a plurality of exchanges in the public network 30 and applied.

  In the first embodiment, the temporary allocation number is inquired to the calling terminal 40 on the condition that the incoming call to the public number is accepted. However, the present invention is not limited to this. For example, a public number including a temporary allocation number is notified in advance to the user of the transmission terminal. For example, the public telephone number of the privacy telephone exchange system 10 can be “03-1234-5678-1234”, and the last “1234” can be a temporary allocation number associated with the privacy number. At this time, when the receiver (first receiving means) 14 accepts an incoming call to the public number, the transmitter 18 corresponds to the temporary allocation number included in the public number accepted by the receiver 14, A call is made to the privacy telephone terminal 50 using the privacy number stored in the registration information of the registration information storage unit 12. In this case, in FIG. 4, the privacy telephone exchange system 10 can be configured by omitting the numeric receiver 16.

2. Second Embodiment In the second embodiment, a management server is provided so that a privacy telephone exchange system applied to a communication system can be operated more flexibly. Then, on the condition that the user of the privacy telephone terminal is charged, the same exchange connection service as that of the first embodiment is provided.

  FIG. 7 shows an outline of the configuration of a communication system to which the privacy telephone exchange system according to the second embodiment is applied. However, the same parts as those in the communication system in the first embodiment shown in FIG.

  The privacy telephone exchange system 100 includes a management server 200. The management server 200 performs registration information registration processing, incoming call history processing of the privacy telephone terminal 50, and charging processing for the privacy telephone terminal 50.

  The management server 200 is connected to the Internet 60. A user terminal (communication terminal in a broad sense) 70 is connected to the Internet 60. A request for registration processing of registration information, a request for referring to an incoming call history, and the like can be made from the user terminal 70 via the Internet 60.

  FIG. 8 shows an outline of the configuration of the privacy telephone exchange system according to the second embodiment. However, the same parts as those in the privacy telephone exchange system 10 in the first embodiment shown in FIG.

  The first difference between the privacy telephone exchange system 100 and the privacy telephone exchange system 10 in the first embodiment is that the privacy telephone exchange system 100 includes a management server 200.

  A second difference between the privacy telephone exchange system 100 and the privacy telephone exchange system 10 is that the management server 200 includes a registration information storage unit.

  The third difference of the privacy telephone exchange system 100 from the privacy telephone exchange system 10 is that the switch unit 20 includes an audio player (audio reproduction means) 110 and an audio database (audio information storage means) 112.

  The management server 200 performs registration processing and incoming call history processing in response to a request from the user terminal 70 via the Internet.

  The audio player 110 outputs audio using the audio information stored in the audio database 112. The voice database 112 stores voice information of a predetermined announcement sentence, voice information corresponding to each number, and voice information corresponding to each character. Then, the audio player 110 uses the audio information stored in the audio database 112 to output the telephone number of the calling terminal as audio. More specifically, the voice reproducer 110 outputs the telephone number of the calling terminal to the privacy telephone terminal 50 using voice information corresponding to the telephone number of the incoming calling terminal received by the receiver 14. To do. It is desirable that the voice player 110 outputs the telephone number of the calling terminal by voice before starting a call with the privacy telephone terminal 50.

  In the second embodiment, the privacy telephone exchange system 100 transmits to the privacy telephone terminal 50. Therefore, when the existing exchange facility is used, the privacy telephone terminal 50 side notifies the public number of the privacy telephone exchange system 100 as the caller number. Therefore, the privacy telephone terminal 50 does not notify the telephone number of the transmission terminal 40 that is the original transmission source. Therefore, by using the sound reproducer 110 as described above, the telephone number of the calling terminal 40 that is the calling source can be notified to the privacy telephone terminal 50.

  It is desirable that the voice player 110 repeats the voice output of the telephone number of the calling terminal 40 until it detects that a predetermined operation has been performed from the privacy telephone terminal 50. By doing so, it is possible to avoid a situation in which the user of the privacy telephone terminal 50 misses the voice output of the telephone number of the calling terminal 40. In this case, the number receiver 16 can detect whether the privacy telephone terminal 50 has performed a predetermined operation by detecting a signal transmitted when the privacy telephone terminal 50 presses a predetermined number key.

The registration information generated by the registration information generation unit 226 is stored in the registration information storage unit 252.

  The temporary allocation number notifying unit 228 notifies the user terminal 70 of the temporary allocation number. For example, control is performed to transmit an e-mail including the temporary allocation number to the user terminal 70 via the communication unit 280, or display data for displaying a display screen including the temporary allocation number is transmitted to the user terminal 70. Can be controlled.

  FIG. 11 shows a functional block diagram of the incoming call history processing unit 230.

  The incoming call history processing unit 230 includes an incoming call history information generating unit 232, an incoming call history reading receiving unit 234, and an incoming call history information output unit 236.

  The incoming call history information generation means 232 monitors the receiver 14 of the privacy telephone exchange system 100 and accumulates the incoming call history, and the incoming call history to the privacy number (temporary allocation number) is the incoming call history information associated with the privacy number. Generate. The incoming call history information is stored in the incoming call history information storage unit 254.

  FIG. 12 shows an example of incoming call history information.

  The incoming call history information includes a call start time, a call end time, and a caller number. The call start time is the time when the call between the calling terminal 40 and the privacy telephone terminal 50 is started. The call end time is the time when the call ends. The caller number is the telephone number of the calling terminal 40.

  The call start time and call end time are monitored by switching the transmission line between the calling terminal 40 and the privacy telephone terminal 50 by the switch unit 20 and monitoring the time when the call is started and the time when the call is ended. Can get. The caller ID is notified from the caller terminal 40 when the receiver 14 receives an incoming call from the caller terminal 40.

  Such incoming call history information is stored for each privacy number.

  In FIG. 11, an incoming call history reading accepting unit 234 accepts an incoming call history read request from a given communication terminal (user terminal 70 or another user terminal). For example, by receiving display data for displaying a reception history reading reception screen to the user terminal and instructing a predetermined position on the reception screen displayed on the communication terminal with a pointing device, the incoming history reading reception means 234 accepts an incoming call history read request. Therefore, the incoming call history reading accepting unit 234 can perform control to transmit the display data to the user terminal via the communication unit 280 and receive the read request.

  The incoming call history information output unit 236 receives an incoming call history reading request from a given communication terminal (the user terminal 70 or another user terminal) by the incoming call history read receiving unit 234, and receives the incoming call history information from the incoming call history information storage unit 254. Read incoming call history information. Then, the incoming call history information output unit 236 outputs the incoming call history information to the communication terminal. More specifically, the incoming call history information output unit 236 generates display data for displaying the incoming call history information read from the incoming call history information storage unit 254 on the user terminal as shown in FIG. Send to user terminal. Therefore, the incoming call history information output unit 236 can perform control to transmit the display data to the user terminal via the communication unit 280.

  In FIG. 13, use points and use points are displayed for each incoming call to the privacy telephone terminal 50. The user of the privacy telephone terminal 50 can receive a service for the number of usage points set according to the payment amount after paying a fee by, for example, a prepaid method. In FIG. 13, the used points consumed for each incoming call are displayed, and the remaining used points are also displayed.

  FIG. 14 shows a functional block diagram of the charging processing unit 240.

  As described above, in the second embodiment, the charging processing unit 240 charges the user of the privacy telephone terminal 50. Therefore, the user can receive the above-described exchange connection service by paying a fee by a prepaid method or a credit settlement method.

  In the case of the prepaid method, the registration information in the second embodiment includes a usage point that is set according to the payment fee of the user of the privacy telephone terminal 50.

  FIG. 15 shows an example of registration information in the second embodiment.

  The registration information in the second embodiment includes a use point associated with a privacy number. When there is an incoming call to the privacy telephone terminal 50, for example, the value of the use point decreases according to the call time.

  As shown in FIG. 15, the registration information may include at least one of an incoming call permission number and an incoming call rejection number in association with the temporary allocation number.

  The incoming call permission number is the telephone number of the calling terminal 40 that permits the incoming call to the receiver 14 to connect to the privacy telephone terminal 50. The incoming call rejection number is the telephone number of the calling terminal 40 that refuses to connect the incoming call to the receiver 14 to the privacy telephone terminal 50.

  When the telephone number of the transmission terminal 40 that is the source of the incoming call to the receiver 14 matches the incoming call permission number corresponding to the temporary allocation number notified from the transmission terminal 40, the transmitter 18 associates with the temporary allocation number. A call is made to the privacy telephone terminal 50 using the given privacy number.

  When the telephone number of the transmission terminal 40 that is the source of the incoming call to the receiver 14 matches the incoming call rejection number corresponding to the temporary allocation number notified from the transmission terminal 40, the transmitter 18 sets the temporary allocation number to the temporary allocation number. No call is made to the privacy telephone terminal 50 using the associated privacy number (the call is omitted).

  In order to perform the charging process using the usage points included in the registration information, the charging processing unit 240 includes a registration information update unit 242 and a user notification unit 244 as shown in FIG.

  The registration information update unit 242 performs processing for updating the registration information stored in the registration information storage unit 252. More specifically, the registration information update unit 242 performs processing for updating the use point of the registration information. When the usage point is the first point (for example, 100 points) or more, the present service can be received. When the usage point becomes lower than the first point, the user notification means 244 notifies the privacy telephone terminal 50 that the usage point has become smaller than the first point in order to continue receiving this service. To do. For example, it is possible to perform control to transmit an e-mail including a message indicating that the use point has become smaller than the first point to the privacy telephone terminal 50 via the communication unit 280.

  Next, the operation of the privacy telephone exchange system 100 in the second embodiment configured as described above will be described.

  FIG. 16 shows an example of the registration processing flow of the registration processing unit 220.

  The processing unit 210 waits for a registration request from the user terminal 70 via the communication unit 280 (step S30: N). When the processing unit 210 detects a registration request from the user terminal 70 via the communication unit 280 (step S30: Y), the registration processing unit 220 starts registration processing of registration information.

  In the registration processing unit 220, the privacy number receiving unit 222 receives input of registration information (step S31). For example, the privacy number receiving unit 222 transmits display data for displaying a registration screen as shown in FIG. 17 via the communication unit 280. FIG. 17 is a screen image for accepting input of a user name for using the service, a notification e-mail address, and a privacy number. Further, it is possible to accept a charge request for a usage point corresponding to the payment fee by the prepaid method. FIG. 17 shows a screen image when accepting selection of a usage point to be charged (a usage point larger than the first point) and credit card information for paying a fee.

  In the user terminal 70, for example, by selecting a transmission button with a pointing device, input information including a privacy number input at a predetermined position on the registration screen is received by the communication unit 280 via the Internet 60. The privacy number receiving means 222 determines whether or not input information has been input according to a predetermined format, and transmits display data for displaying a content confirmation screen to the privacy telephone terminal 50 again (step S32).

  When notified from the user terminal 70 that there is no problem in content confirmation, the temporary assignment number assigning means 224 assigns a temporary assignment number corresponding to this privacy number (step S33).

  Then, the registration information generation unit 226 generates registration information by associating the privacy number with the temporary allocation number (step S34) and stores the registration information in the registration information storage unit 252.

  The temporary allocation number notifying means 228 transmits an e-mail including the registration information generated in step S34 and the public number allocated to the privacy telephone exchange system 100 to the e-mail address input in step S31 (step S31). S35).

  In step S35, instead of transmitting the registration content by e-mail, display data for displaying a registration content confirmation screen as shown in FIG. 18 may be transmitted to the user terminal 70.

  It is desirable to start providing services after registration information has been registered and payment has been confirmed. The service is provided when the usage point set by the user paying a fee is equal to or higher than the first point. For this reason, when the usage points are decreased due to the provision of the service, the user can charge the usage points again by an operation from the user terminal 70.

  FIG. 19 is a flowchart showing an example of a registration information update process by charging a usage point.

  The processing unit 210 waits for a usage point charge request from the user terminal 70 via the communication unit 280 (step S40: N). When the processing unit 210 detects a usage point charge request from the user terminal 70 via the communication unit 280 (step S40: Y), the registration information update process is started.

  The registration information update unit 242 accepts the charge input of the usage points (step S41). For example, the registration information update unit transmits display data for displaying a use point charge screen as shown in FIG. 20 via the communication unit 280. FIG. 20 shows a screen image for selecting the number of usage points to be charged after showing the public number and the temporary allocation number. Further, FIG. 20 shows a screen image when accepting credit card information for paying a fee corresponding to the selected use point.

  In the user terminal 70, for example, by selecting a transmission button with a pointing device, information on the usage points and credit cards selected on the usage point charge screen is received by the communication unit 280 via the Internet 60. The registration information update unit 242 holds information on the selected usage points and credit cards, and when the payment is actually made at a later date (step S42: Y), the registration information stored in the registration information storage unit 252 is stored. And the registration information updated to the usage point corresponding to the deposit amount is stored again in the registration information storage unit 252 (step S43). Confirmation of payment can be performed based on a notice from a credit company, for example.

  In step S42, if the payment from the user is not confirmed even after a predetermined period of time has elapsed after the input is accepted (step S42: N), the registration information update unit 242 does not update the registration information, and does not update the usage information. The series of charging processes ends (END).

  Next, a processing example of the management server 200 will be described.

  21 and 22 are flowcharts of processing examples of the management server 200. Here, an example of a flow in which a service is being provided after registration information registration processing has been performed and usage points have been charged as described above.

  First, the privacy telephone exchange system 100 accepts an incoming call in the same manner as in the first embodiment. That is, the receiver 14 monitors whether there is an incoming call from a calling terminal using a public number. When the receiver 14 detects an incoming call from the calling terminal using the public number and accepts the incoming call, the number receiver 16 requests the calling terminal to notify the temporary allocation number, and the calling terminal temporarily Accept assignment number.

  The management server 200 monitors whether there is an incoming call in the privacy telephone exchange system 100 (step S50: N). Then, when the temporary allocation number is received from the calling terminal, the management server 200 determines that there is an incoming call (step S50: Y), and the processing unit 210 receives the registration information shown in FIG. 15 from the registration information storage unit 252. Is read (step S51).

  Subsequently, the processing unit 210 searches the registration information using the accepted temporary assignment number as a search key, and specifies the privacy number associated with the temporary assignment number (step S52).

  When there is a privacy number (step S53: Y), the processing unit 210 reads the incoming call permission number and incoming call rejection number associated with the temporary allocation number received by the number receiver 16. When the read incoming permission number matches the telephone number of the caller terminal 40 that is the caller of the incoming call received by the receiver 14 (step S54: Y), the processing unit 210 indicates that the read incoming call rejection number is the receiver It is determined whether or not it matches the telephone number of the caller terminal 40 that is the caller of the incoming call received at 14 (step S55).

  When it is determined that the incoming call rejection number does not match the telephone number of the calling terminal 40 (step S55: N), the processing unit 210 instructs the control unit 22 to make a call using the transmitter 18 (step S56). Then, the processing unit 210 starts generating or updating incoming call history information in the incoming call history information generating unit 232 (step S57). For example, the call start time is set in the incoming call history information.

  On the other hand, when it is determined in step S53 that the received temporary allocation number does not exist and there is no privacy number as a result of searching the registration information (step S53: N), the incoming call permission number is set to the calling terminal 40 in step S54. If the incoming call rejection number matches the telephone number of the calling terminal 40 in step S55 (step S55: Y), the processing unit 210 instructs the control unit 22 to Then, the notification of guidance by the audio player 110 is instructed (step S58).

  When it is determined in step S53 that there is no privacy number (step S53: N), the guidance notification instructs the transmission terminal 40 to output a voice message indicating that the privacy number is not registered. Further, the guidance notification instructs to output to the calling terminal 40 a voice message indicating that the incoming call is not permitted when the incoming call permission number does not match the telephone number of the calling terminal 40 in step S54 (step S54: N). . Alternatively, the guidance notification instructs the outgoing terminal 40 to output a voice message indicating that the incoming call is rejected when the incoming call rejection number matches the telephone number of the outgoing terminal 40 in step S55 (step S55: Y). . In the guidance notification, the control unit 22 may be instructed to disconnect the incoming call from the transmission terminal 14 by the receiver 14 after a predetermined time has elapsed after the guidance notification.

  After the notification of the guidance, the incoming call history information generation unit 232 updates the incoming call history information so as to include, for example, the content indicating that the incoming call is not permitted or the incoming call is rejected (step S59).

  In step S56 and subsequent steps, a call path between the calling terminal 40 and the privacy telephone terminal 50 is established. Meanwhile, the management server 200 performs a billing process for the privacy telephone terminal 50.

  When charging to the privacy telephone terminal 50 is a prepaid method and a usage point is set (step S60: Y), the charging processing unit 240 determines whether or not the usage point is smaller than the first point. (Step S61).

  When it is determined that the usage point is equal to or higher than the first point (step S61: N), the charging processing unit 240 updates the usage point (step S62). For example, every time a predetermined time elapses, the usage points are subtracted by one point.

  When the end of the call is not notified from the control unit 22 (step S63: N), the process returns to step S61.

  When it is determined in step S61 that the usage point is smaller than the first point (step S61: Y), the user notification unit 244 notifies the privacy telephone terminal 50 of an alarm (step S64). For example, the user notification unit 244 may send an e-mail indicating that the use point is smaller than the first point to the e-mail address set at the time of registration, or the privacy telephone terminal 50 is busy. An alarm sound may be output.

  After the alarm notification, the billing processing unit 240 instructs the control unit 22 to forcibly disconnect the speech path at the receiver 14, the transmitter 18, and the switch unit 20 (step S65). In addition, when the usage point becomes smaller than the first point and the call is continued and the usage point finally becomes 0, the billing processing unit 240 sends the receiver 14, the transmitter to the control unit 22. 18 and the switch unit 20 are preferably instructed to forcibly disconnect the communication path. This makes it possible to easily limit the use of users who do not respond to billing.

  On the other hand, when charging to the privacy telephone terminal 50 is not a prepaid method in step S60 (step S60: N), a predetermined billing notification process is instructed to charge a postpaid fee (step S66). In the billing notification process, a process of requesting the user of the privacy telephone terminal 50 to pay a fee corresponding to the call time after the call is finished is performed. Thereafter, the control unit 22 waits until the end of the call is notified (step S67: N). When the end of the call is notified (step S67: Y), the process proceeds to step S68.

  When the end of the call is notified from the control unit 22 (step S63: Y, step S67: Y), the call end time is set in the incoming call history information and the incoming call history information is updated (step S68). Following step S65, information indicating that the call is forcibly disconnected is set in the incoming call history information (step S68).

  Then, the registration information update unit 242 performs a registration information update process in which the use points updated in step S62 are reflected in the registration information (step S69), and the series of processes ends (end).

  As described above, the management server 200 can centrally manage registration information and incoming call history information. Therefore, the administrator of the management server 200 can easily grasp the overall usage status of the service and the personal usage status of the service. For example, as shown in FIG. 23, the use status can be easily grasped by a display screen showing the overall use status of the service. In this case, the management server 200 reads registration information in response to an output request for the overall usage status of the service from the administrator, and displays a usage status introduction screen on the display unit 260 based on the registration information. In addition, by selecting a user on the screen shown in FIG. 23, it is possible to inquire the user's incoming history as shown in FIG.

  The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the present invention.

  For example, in the second embodiment, the registration information storage unit is provided in the management server. However, the control unit 22 may be configured to be directly accessible as in the first embodiment.

  In the invention according to the dependent claims of the present invention, a part of the constituent features of the dependent claims can be omitted. Moreover, the principal part of the invention according to one independent claim of the present invention may be made dependent on another independent claim.
