  For example, in the case of making an outside call from an extension telephone in a company, the telephone of the called party is notified of the representative number of the company as the calling party number by the processing of the PBX. Therefore, only the representative number is recorded in the incoming call history of the incoming call destination telephone, and for example, when the incoming call destination can not answer in absence, the callee can directly call back to the telephone corresponding to the incoming call number. However, it is not possible to call back directly to the originating extension. Also, the caller can not answer, for example, when he / she is away from his / her extension telephone when going out etc. when there is a call back from the called party.

  Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a call control system and a call control method for improving the convenience of call back transmission.

  FIG. 1 is a block diagram showing an example of a call control system. The call control system includes communication control servers 1 and 3, contract management server 2, PBX 40, telephones 6, 41 and 42, and portable communication terminals 50 and 51. The call control system further includes layer 2 switches (L2 switches) 912 and 922, routers 910 and 920, a base station 921, a gateway (GW) server 930, a line termination device 911 and a subscriber line exchange 931. including.

  The GW server 930 and the subscriber line exchange 931 are connected to a public telephone network 93. The GW server 930 controls the transfer path of packets with the public communication network 90 such as the Internet. The subscriber line exchange 931 exchanges the telephone line of the telephone 6. “06-BBBB-bbbb” (B, b: an integer of 0 to 9) is set as the telephone number of the telephone set 6 and is used by the user B. The telephone 6 is an example of a destination terminal.

  The router 910, the line termination device 911, and the layer 2 switch 912 are connected to the communication network 91. The communication control server 1 is connected to the communication network 91 via the layer 2 switch 912, and packets addressed to the own device are transferred from the layer 2 switch 912. The router 910 is connected to the public communication network 90 and controls a packet transfer path. The packet may be, for example, an IP (Internet Protocol) packet or an ATM (Asynchronous Transfer Mode) cell, but is not limited thereto.

  The PBX 40 and the telephones 41 and 42 are connected to each other to configure an extension telephone system. The PBX 40 is installed, for example, on the premises of the company X who is the user, and “06-XXXX-xxxx” is set as the representative telephone number of the company X. The telephone set 41 is set with an extension number y, and has a representative telephone number “06-XXXX-xxxx” (X, x: an integer of 0 to 9) as an outside line telephone number. The telephone 42 is an example of a source terminal, and the extension number z is set, and is used by the user A. The telephones 41 and 42 are connected to the communication network 91 via the PBX 40.

  The PBX 40 is connected to the line termination device 911. The line termination device 911 performs termination processing of the telephone line of the PBX 40 and performs conversion processing of a communication protocol with the communication network 91. When the PBX 40 receives an outside call from the telephones 41 and 42, the PBX 40 transmits an origination signal to the communication control server 1 as the representative telephone number "06-XXXX-xxxx". When the PBX 40 receives an incoming call from the communication control server 1, the PBX 40 transmits an incoming call signal to the telephone 41 having the representative telephone number instead of the telephone 42.

  The communication control server 1 is an example of a call control device, and controls calls of the telephones 41 and 42 connected to the communication network 91. The communication control server 1 transmits a call signal based on the outgoing call signal received from the telephones 41 and 42.

  The router 920, the base station 921, and the layer 2 switch 922 are connected to the communication network 92. The contract management server 2 and the communication control server 3 are connected to the communication network 92 via the layer 2 switch 922, and packets addressed to the own device are transferred from the layer 2 switch 922. The router 920 is connected to the public communication network 90 and controls a packet transfer path. Note that the operator operating the communication network 92 is different from the operator operating the communication network 91.

  The base station 921 is connected to the portable communication terminal 51 via radio. Examples of the mobile communication terminals 50 and 51 include, but are not limited to, a smartphone and a mobile phone, for example. “090-AAAA-aaaa” (A, a: integer of 0 to 9) is set as the telephone number of the portable communication terminal 51, and is used by the same user A as the telephone set 42.

  The communication control server 3 controls calls of the portable communication terminals 50 and 51 connected to the communication network 92. The communication control server 3 transmits a call signal based on the outgoing call signal received from the portable communication terminals 50 and 51.

  The contract management server 2 receives from the portable communication terminals 50 and 51 connected to the communication network 92 a contract for a notification service of a return telephone number and registration of a personal identification number used for the notification service (see reference symbol R1). The call back telephone number notification service, as described later, is to notify an incoming call destination of a designated number different from that of a call originator on the condition that authentication with a personal identification number is successful when making a call.

  In this example, the user A registers the PIN number in the contract management server 2 with the telephone number of the portable communication terminal 51 as the designated number. Thereby, when the user A makes a call from the telephone 42 to the telephone 6 of the receiving destination, the user B of the telephone 6 can be notified of the telephone number "090-AAAA-aaaa" of the portable communication terminal 51.

  Therefore, even if the user A is away from the telephone 42, the portable communication terminal 51 can receive the return transmission from the telephone 6, which is the called party, and respond. That is, even if the user A changes the use object from the telephone 42 to the portable communication terminal 51 (see “use change”), the user A can respond to the user B's call back transmission. The contract management server 2 registers the presence / absence of a contract and the personal identification number in the authentication table in association with the telephone numbers of the portable communication terminals 50 and 51, as described below.

  FIG. 2 is a block diagram showing an example of the authentication table. In the authentication table, the telephone numbers of the portable communication terminals 50 and 51, the presence or absence of a contract for notification service, and the personal identification number (first personal identification number) are registered in association with each other. For example, the contract of the notification service of the portable communication terminal 51 of the telephone number "090-AAAA-aaaa" is "presence", and the password is "0123". The contract for the notification service of the portable communication terminal of the telephone number "090-BBBB-bbbb" is "presence", and the password is "3210". The contract for the notification service of the portable communication terminal with the telephone number "090-CCCC-cccc" is "none".

  Referring again to FIG. 1, a case will be described by way of example where the telephone 42 of the communication network 91 makes a call to the telephone 6 of the public telephone network 93. Here, it is assumed that the user A of the telephone 42 has registered the contract of the notification service of the portable communication terminal 51 and the password “0123” in the contract management server 2 in advance.

  At the time of making a call, the user A not only receives the telephone number "06-BBBB-bbbb" of the destination telephone 6, but also the designated number "090-AAAA-aaaa", which is the telephone number to be notified, and the PIN (first PIN ) "0123" is input to the telephone 42. As a result, a series of numbers including the destination number "06-BBBB-bbbb", the designated number "090-AAAA-aaaa", and the password "0123" is transmitted as a transmission signal (see reference symbol R2). Here, since the user A only needs to input the called party number “06-BBBB-bbbb”, the designated number “090-AAAA-aaaa”, and the password “0123” as a series of numbers, the user A normally uses the telephone 42. It is possible to make a call by performing the input operation (dial input) of the numeric keys of. The call origination signal transmitted from the telephone set 42 is transmitted to the communication control server 1 with the representative telephone number “06-XXXX-xxxx” of the company X assigned thereto as the transmission source number in the PBX 40.

  FIG. 3 shows an example of the called number, the designated number, and the password. In the transmission signal, a character code G is inserted to separate the destination number "06-BBBB-bbbb", the designated number "090-AAAA-aaaa", and the password "0123" within a series of numbers. The communication control server 1 detects the character code G from the series of numbers in the outgoing signal, and from the series, the destination number "06-BBBB-bbbb", the designated number "090-AAAA-aaaa", and the password The number "0123" is acquired individually.

  More specifically, the communication control server 1 separates the destination number "06-BBBB-bbbb", the designated number "090-AAAA-aaaa", and the password "0123" from one another by using the character code G as a mark. . Therefore, the communication control server 1 can easily obtain the destination number “06-BBBB-bbbb”, the designated number “090-AAAA-aaaa”, and the password “0123” from the series of numbers. In addition, in this example, although "#" is mentioned as a character code G, it is not limited to this.

  The communication control server 1 authenticates the designated number by comparing the acquired designated number “090-AAAA-aaaa” and the password “0123” with the telephone number and the password registered in the authentication table of the contract management server 2. Do the processing. In the present embodiment, the contract management server 2 and the portable communication terminal 51 corresponding to the designated number are connected to the communication network 92 different from the telephone set 42 which is the source terminal.

  Therefore, the communication control server 1 performs authentication processing of the designated number via the communication control server 3 in the communication network 92. More specifically, the communication control server 1 transmits, as an authentication request, a transmission signal including the password "0123" in the header portion to the communication control server 3 according to the designated number "090-AAAA-aaaa" Refer to code R3).

  When the communication control server 3 receives the transmission signal of the authentication request from the communication control server 1, the communication control server 3 acquires the telephone number and the personal identification number in the authentication table from the contract management server 2. The communication control server 3 collates the designated number “090-AAAA-aaaa” and the code number “0123” with the telephone number and the code number in the authentication table. The communication control server 3 notifies the communication control server 1 of the result of the collation.

  As described above, the communication control server 1 performs the authentication process of the designated number even when the contract management server 2 and the portable communication terminal 51 of the designated number are connected to the communication network 92 other than that of the own device. Can.

  When the authentication processing is successful, the communication control server 1 replaces the telephone number "06-XXXX-xxxx" corresponding to the telephone 42, and uses the designated number "090-AAAA-aaaa" as the source number, and the destination number "06. Make a call to "BBBB-bbbb" (see code R4). As a result, since the designated number "090-AAAA-aaaa" is notified to the destination telephone 6, the user B returns to the designated number "090-AAAA-aaaa" even if the user B can not answer because of absence. A call can be made to user A by making a call.

  In addition, when the authentication processing fails, the communication control server 1 cancels the call to the destination number “06-BBBB-bbbb”. Therefore, for example, it is prevented that a malicious third party, not the user A, makes a call from the telephone 42 to the telephone 6 of the user B using the notification service.

  Next, the configurations of the communication control servers 1 and 3 will be described. FIG. 4 is a configuration diagram showing an example of the communication control server 1 and 3.

  The communication control servers 1 and 3 have a central processing unit (CPU) 10, a read only memory (ROM) 11, a random access memory (RAM) 12, a hard disk drive (HDD) 13, and a plurality of communication ports 14.

  The CPU 10 is connected to the ROM 11, the RAM 12, the HDD 13, and a plurality of communication ports 14 via a data bus 15 so that they can input and output signals to each other. The ROM 11 stores a program for driving the CPU 10. The RAM 12 functions as a working memory of the CPU 10. The communication port 14 includes, for example, a PHY (Physical layer) chip, and transmits and receives packets to and from another device such as the layer 2 switch 912. The communication port 14 is an example of a receiving unit, and receives an outgoing signal from the telephone 42 of the source terminal, that is, a series of numbers including a destination number, a designated number, and a personal identification number.

  The HDD 13 holds route information 130 indicating a packet transfer route, and a number translation table 131 used for number translation processing of the destination number. The means for holding the path information 130 and the number translation table 131 is not limited to the HDD 13, and may be, for example, an SDRAM (Synchronous Dynamic RAM).

  When the CPU 10 reads a program from the ROM 11, a call processing unit 101, a signal processing unit 102, an authentication processing unit 103, and a route searching unit 104 are formed as functions. The call processing unit 101, the signal processing unit 102, the authentication processing unit 103, and the route search unit 104 are not limited to those operating with software as described above, but operate with hardware such as a field programmable gate array (FPGA). It may be

  The call processing unit 101 controls calls of the telephones 41 and 42 connected to the communication network 91. More specifically, the call processing unit 101 performs call processing and call termination processing.

  In the example described above, when the call processing unit 101 succeeds in the authentication process of the designated number “090-AAAA-aaaa”, the call processing unit 101 replaces the telephone number “06-XXXX-xxxx” corresponding to the telephone 42 of the source terminal. Call the destination number "06-BBBB-bbbb" with the designated number "090-AAAA-aaaa" as the source number. Also, when the authentication processing of the designated number “090-AAAA-aaaa” fails, the call processing unit 101 cancels the call to the destination number “06-BBBB-bbbb”. The call processing unit 101 uses the number translation table 131 to translate the designated number and the called number.

  The signal processing unit 102 is an example of an acquisition unit, detects the character code G described above, and separately acquires a called party number, a designated number, and a personal identification number from a series of numbers, and the call processing unit 101 and authentication The processing unit 103 is notified. Further, when the character code G is not detected from the series of numbers, the signal processing unit 102 acquires only the destination number and notifies the call processing unit 101. In this case, the call processing unit 101 calls the destination number using the telephone number "06-XXXX-xxxx" corresponding to the telephone 42 of the source terminal as the source number. Therefore, the user A can notify the user B of the representative telephone number "06-XXXX-xxxx" of the company X instead of the telephone number "090-AAAA-aaaa" of the portable communication terminal 51.

  The authentication processing unit 103 collates the designated number and the personal identification number acquired by the signal processing unit 102 with the telephone number and the personal identification number of the portable communication terminals 50 and 51 registered in the authentication table of the contract management server 2. Perform authentication processing of the specified number. In the example described above, the authentication processing unit 103 of the communication control server 1 performs an authentication process via the authentication processing unit 103 of the communication control server 3 in the communication network 92. The authentication processing unit 103 of the communication control server 3 acquires the authentication information registered in the authentication table from the contract management server 2 via the layer 2 switch 922 and performs the collation process. The collation result is transmitted to the communication control server 1 via the communication port 14.

  The route search unit 104 determines a transfer route of a packet including an outgoing call signal and a call signal based on the route information 130. The route search unit 104 transmits a packet from the communication port 14 corresponding to the transfer route.

  FIG. 5 is a block diagram showing an example of the contract management server 2. The contract management server 2 has a CPU 20, a ROM 21, a RAM 22, an HDD 23, and a plurality of communication ports 24.

  The CPU 20 is connected to the ROM 21, the RAM 22, the HDD 23, and a plurality of communication ports 24 via a data bus 25 so that signals can be input to and output from each other. The ROM 21 stores a program for driving the CPU 20. The RAM 22 functions as a working memory of the CPU 20. The communication port 24 includes, for example, a PHY chip, and transmits and receives packets to and from another device such as the layer 2 switch 922.

  The HDD 23 holds the authentication table 230 described with reference to FIG. The means for holding the authentication table 230 is not limited to the HDD 23, and may be, for example, an SDRAM.

  When the CPU 20 reads a program from the ROM 21, a registration processing unit 201 and a reading processing unit 202 are formed as functions. The registration processing unit 201 and the reading processing unit 202 are not limited to those operating with software as described above, and may operate with hardware such as an FPGA.

  The registration processing unit 201 receives registration of the personal identification number from the portable communication terminals 50 and 51 connected to the communication network 92 and registers the same in the authentication table 230. The read processing unit 202 reads authentication information from the authentication table 230 in response to a request from another device, and transmits the read information to the other device via the communication port 24. In the example described above, the read processing unit 202 transmits authentication information to the communication control server 3 in response to a request from the communication control server 3 connected to the same communication network 92 as the contract management server 2.

  Next, processing of the call control system in the above-described example will be described. 6 and 7 are sequence diagrams showing an example of processing of the call control system.

  First, description will be made with reference to FIG. Prior to making a call from the telephone set 42 of company X to the telephone set 6 of user B, user A registers the personal identification number of his portable communication terminal 51 in contract management server 2. When the portable communication terminal 51 receives an operation for registration from the user A, the portable communication terminal 51 transmits a registration request including the personal identification number “01234” to the contract management server 2. When the registration processing unit 201 of the contract management server 2 receives the registration request via the communication port 24, the registration table is stored in the authentication table 230 with the contract "presence" and the password "01234", and the telephone number "090-of the portable communication terminal 51". It is registered so as to correspond to "AAAA-aaaa" (see symbol SQ1). When the registration processing is completed, the registration processing unit 201 transmits a response to the portable communication terminal 51.

  Next, the user A makes a call from the telephone 42 to the telephone 6 of the user B. When making a call, user A receives the telephone number "06-BBBB-bbbb" of the telephone number 6 which is the called number, the designated number "090-AAAA-aaaa" of the return transmission destination notified to user B, and the password. The number "0123" is input to the telephone set 42 as a series of numbers. As a result, a series of numbers including the called party number “06-BBBB-bbbb”, the designated number “090-AAAA-aaaa”, and the personal identification number “0123” is transmitted to the PBX 40 as a transmission signal. At this time, the extension number z is set as the transmission source number of the transmission signal.

  When receiving the outgoing signal, the PBX 40 converts the source number of the outgoing signal into the representative telephone number “06-XXXX-xxxx” of the company X, and transfers the outgoing signal to the communication control server 1. The communication port 14 of the communication control server 1 receives an outgoing signal including a series of numbers.

  When receiving the transmission signal from the communication port 14, the signal processing unit 102 of the communication control server 1 detects the character code G ("#" in this example) from the series of numbers (see the code SQ2). When the character code G is not detected from the series of numbers (see No in the code SQ2), the signal processing unit 102 acquires the called party number “06-BBBB-bbbb” and notifies the call processing unit 101. Call processing section 101 translates the destination number "06-BBBB-bbbb" based on number translation table 131 (see reference numeral SQ5).

  Next, the call processing unit 101 makes a call to the called telephone 6 (see the code SQ6). At this time, the call processing unit 101 transmits a call signal to the telephone set 6 via the communication port 14. The source number of the call signal is the representative telephone number "06-XXXX-xxxx" of the company X, and the destination number of the call signal is the telephone number "06-BBBB-bbbb" of the telephone set 6.

  As a result, the telephone set 6 is notified of the representative telephone number "06-XXXX-xxxx" of the company X as a call back destination. Therefore, the user A can respond to the return call from the user B by the telephone 42.

  On the other hand, when the character code G is detected from the series of numbers (see Yes in the symbol SQ2), the signal processing unit 102 designates the destination number "06-BBBB-bbbb" from the series using the character code as a mark. The number “090-AAAA-aaaa” and the personal identification number “0123” are individually acquired (see symbol SQ3), and notified to the call processing unit 101 and the authentication processing unit 103. Next, the call processing unit 101 translates the destination number "06-BBBB-bbbb" and the designated number "090-AAAA-aaaa" based on the number translation table 131 (see the code SQ4).

  Next, description will be made with reference to FIG. The authentication processing unit 103 of the communication control server 1 transmits the authentication request including the designated number “090-AAAA-aaaa” as the called number and the password “0123” to the mobile phone of the designated number “090-AAAA-aaaa”. The communication control server 3 is connected to the communication network 92 of the master communication terminal 51.

  When the authentication processing unit 103 of the communication control server 3 receives the authentication request via the communication port 14, the authentication processing unit 103 requests the contract management server 2 for authentication information. The read processing unit 202 of the contract management server 2 reads the authentication information from the authentication table 230 and transmits the information to the communication control server 3 via the communication port 24.

  The authentication processing unit 103 of the communication control server 3 collates the designated number “090-AAAA-aaaa” of the authentication request and the password “0123” with the telephone number and password of the authentication information received via the communication port 14. (Refer to the symbol SQ7). The authentication processing unit 103 transmits the result of the collation to the communication control server 1 via the communication port 14.

  Authentication processing unit 103 of communication control server 1 determines the success or failure of the authentication process based on the comparison result received from communication control server 3 via communication port 14 (see symbol SQ8). The success or failure of the authentication process is notified to the call processing unit 101.

  If the authentication process fails, the call processing unit 101 cancels the call origination to the callee 6 (see reference numeral SQ10). For this reason, even if a malicious third party attempts to use the notification service with an incorrect password, the telephone 6 will not be called.

  On the other hand, when the authentication processing is successful, the call processing unit 101 transmits the designated number "090-AAAA-aaaa" in place of the representative telephone number "06-XXXX-xxxx" corresponding to the telephone 42 of the transmission source terminal. Call the destination number "06-BBBB-bbbb" as the number. As a result, the user B is notified of the telephone number "090-AAAA-aaaa" of the portable communication terminal 51 of the user A instead of the representative telephone number "06-XXXX-xxxx".

  Therefore, the user B can return to the portable communication terminal 51 of the user A when the user B can not respond to the transmission from the user A due to, for example, absence. For this return transmission, the source number is "06-BBBB-bbbb" and the destination number is "090-AAAA-aaaa".

  The communication control server 3 transmits a call signal to the portable communication terminal 51 via the base station 921 when the return transmission from the telephone 6 is received. Therefore, even if the user A is away from the telephone 42 used to make a call to the user B, the user A can respond to the return call from the user B at his own portable communication terminal 51. In this way, the call control system performs processing.

  Next, another embodiment will be described. FIG. 8 is a block diagram showing another example of the call control system. In FIG. 8, the same components as in FIG. 1 will be assigned the same reference numerals and descriptions thereof will be omitted.

  Unlike the example shown in FIG. 1, another portable communication terminal 52 of the user A is connected to the communication network 92. In the mobile communication terminal 52, a telephone number "090-EEEE-eeee" (E, e: an integer of 0 to 9) is set.

  The communication control server 3 is an example of a call control device, and controls calls of the portable communication terminals 51 and 52 connected to the communication network 92. The communication control server 3 transmits a call signal based on the outgoing call signal received from the portable communication terminals 51 and 52.

  The contract management server 2 receives a contract for a notification service of a return telephone number and registration of a personal identification number used for the notification service from the portable communication terminals 51 and 52 connected to the communication network 92 (see reference symbol R11).

  In this example, the user A registers the personal identification number “0123” in the contract management server 2 with the telephone number of the portable communication terminal 51 as the designated number. Thereby, when the user A makes a call from the other portable communication terminal 52 to the telephone 6 of the receiving destination, the user B of the telephone 6 is notified of the telephone number "090-AAAA-aaaa" of the portable communication terminal 52. it can.

  Therefore, for example, when the portable communication terminal 52 is a business-use portable telephone and the other portable communication terminal 51 is a private-use portable telephone, the user A can receive the call from the telephone 6 which is the destination even after leaving the company. Can be received by the portable communication terminal 51 as a response. That is, even if the user A changes the use object from the portable communication terminal 52 to the portable communication terminal 51 (refer to “use change”), the user A can respond to the user B's return transmission.

  In the following, the case of making a call from the portable communication terminal 52 of the communication network 92 to the telephone 6 of the public telephone network 93 will be described as an example. Here, it is assumed that the user A of the portable communication terminal 52 has registered in advance the contract of the notification service of the portable communication terminal 51 and the password “0123” in the contract management server 2.

At the time of making a call, the user A inputs a series of numbers of the destination telephone number “06-BBBB-bbbb”, the designated number “090-AAAA-aaaa” and the password “0123” into the portable communication terminal 52 . As a result, a series of numbers including the destination number "06-BBBB-bbbb", the designated number "090-AAAA-aaaa", and the personal identification number "0123" is transmitted as a transmission signal (see the code R12). The transmission signal transmitted from the portable communication terminal 52 is transmitted to the communication control server 3 connected to the same communication network 92.

  The communication control server 3 detects the character code G from the series of numbers in the outgoing signal, and from the series, the destination number "06-BBBB-bbbb", the designated number "090-AAAA-aaaa", and the password The number "0123" is acquired individually. The communication control server 3 matches the acquired designated number “090-AAAA-aaaa” and the password “0123” with the telephone number and the password registered in the authentication table 230 of the contract management server 2. Perform authentication process. In the present embodiment, the contract management server 2 and the portable communication terminal 51 corresponding to the designated number are connected to the same communication network 92 as the portable communication terminal 52 which is the source terminal.

  For this reason, the communication control server 3 acquires the telephone number and the personal identification number in the authentication table from the contract management server 2 and performs the authentication process of the designated number (see the code R13). The communication control server 3 collates the designated number “090-AAAA-aaaa” and the code number “0123” with the telephone number and the code number in the authentication table. The communication control server 3 determines that the authentication process is successful if both match as a result of the comparison, and determines that the authentication process fails if both do not match.

  If the communication control server 3 succeeds in the authentication process, it replaces the telephone number "090-EEEE-eeee" corresponding to the portable communication terminal 52, and uses the designated number "090-AAAA-aaaa" as the source number to receive the call. A call is made to the number "06-BBBB-bbbb" (see code R14). As a result, since the designated number "090-AAAA-aaaa" is notified to the destination telephone 6, the user B returns to the designated number "090-AAAA-aaaa" even if the user B can not answer because of absence. A call can be made to user A by making a call.

  In addition, when the authentication processing fails, the communication control server 3 cancels the call to the destination number “06-BBBB-bbbb”. For this reason, for example, it is prevented that the third party who is not malicious, but the user A, makes a call from the portable communication terminal 52 to the telephone 6 of the user B using the notification service.

  Next, processing of the call control system in this example will be described. 9 and 10 are sequence diagrams showing an example of processing of the call control system. In FIG. 9, the same components as those in FIG. 7 will be assigned the same reference numerals and descriptions thereof will be omitted.

  The user A makes a call from the portable communication terminal 52 to the phone 6 of the user B. When making a call, user A receives the telephone number "06-BBBB-bbbb" of the telephone number 6 which is the called number, the designated number "090-AAAA-aaaa" of the return transmission destination notified to user B, and the password. The number "0123" is input to the telephone set 42 as a series of numbers. As a result, a series of numbers including the called party number “06-BBBB-bbbb”, the designated number “090-AAAA-aaaa”, and the personal identification number “0123” is transmitted to the communication control server 3 as a transmission signal. At this time, the telephone number "090-EEEE-eeee" of the portable communication terminal 52 is set as the transmission source number of the transmission signal.

  When the signal processing unit 102 of the communication control server 3 receives the transmission signal from the communication port 14, the signal processing unit 102 detects a character code G ("#" in this example) from the series of numbers (see the code SQ21). When the character code G is not detected from the series of numbers (see No in symbol SQ21), the signal processing unit 102 acquires the called party number “06-BBBB-bbbb” and notifies the call processing unit 101. Call processing section 101 translates the destination number "06-BBBB-bbbb" based on number translation table 131 (see symbol SQ24).

  Next, the call processing unit 101 makes a call to the called telephone 6 (see the code SQ 25). At this time, the call processing unit 101 transmits a call signal to the telephone set 6 via the communication port 14. The source number of the call signal is the telephone number "090-EEEE-eeee" of the portable communication terminal 52, and the destination number of the call signal is the telephone number "06-BBBB-bbbb" of the telephone set 6.

  As a result, the telephone number "090-EEEE-eeee" of the portable communication terminal 52 is notified to the telephone set 6 as a return destination. Therefore, the user A can respond to the return transmission from the user B at the portable communication terminal 52.

  On the other hand, when the character code G is detected from the series of numbers (see Yes in symbol SQ21), the signal processing unit 102 designates the destination number "06-BBBB-bbbb" from the series using the character code as a marker. The number “090-AAAA-aaaa” and the personal identification number “0123” are individually acquired (see symbol SQ22), and notified to the call processing unit 101 and the authentication processing unit 103. Next, the call processing unit 101 translates the destination number "06-BBBB-bbbb" and the designated number "090-AAAA-aaaa" based on the number translation table 131 (see reference numeral SQ23).

    Next, description will be made with reference to FIG. When the authentication processing unit 103 of the communication control server 3 receives the authentication request via the communication port 14, the authentication processing unit 103 requests the contract management server 2 for authentication information. The read processing unit 202 of the contract management server 2 reads the authentication information from the authentication table 230 and transmits the information to the communication control server 3 via the communication port 24.

  The authentication processing unit 103 of the communication control server 3 collates the designated number “090-AAAA-aaaa” of the authentication request and the password “0123” with the telephone number and password of the authentication information received via the communication port 14. (Refer to the symbol SQ26). Authentication processing unit 103 of communication control server 3 determines the success or failure of the authentication process based on the comparison result (see reference numeral SQ 27).

  If the authentication process fails, the call processing unit 101 cancels the call origination to the callee 6 (see reference numeral SQ28). For this reason, even if a malicious third party attempts to use the notification service with an incorrect password, the telephone 6 will not be called.

  On the other hand, when the authentication processing is successful, the call processing unit 101 replaces the telephone number "090-EEEE-eeee" corresponding to the portable communication terminal 52 of the originating terminal with the designated number "090-AAAA-aaaa". Call the destination number "06-BBBB-bbbb" as the source number. Thereby, the user B is notified of the telephone number "090-AAAA-aaaa" of the portable communication terminal 51 of the user A instead of the telephone number "090-EEEE-eeee".

  Therefore, the user B can return to the portable communication terminal 51 of the user A when the user B can not respond to the transmission from the user A due to, for example, absence. For this return transmission, the source number is "06-BBBB-bbbb" and the destination number is "090-AAAA-aaaa".

  The communication control server 3 transmits a call signal to the portable communication terminal 51 via the base station 921 when the return transmission from the telephone 6 is received. Therefore, even if the user A is away from the portable communication terminal 52 used to transmit to the user B, the other portable communication terminal 51 can respond to the return transmission from the user B. In this way, the call control system performs processing.

  As described above, the call control system according to the embodiment includes the communication control servers 1 and 3 which respectively control calls of the telephone set 42 and the portable communication terminal 52 which are source terminals, and the telephones of the portable communication terminal 51. And a contract management server 2 having an authentication table 230 registered in association with a number and a password. The communication control servers 1 and 3 each include a communication port 14, a signal processing unit 102, an authentication processing unit 103, and a call processing unit 101.

  The communication port 14 receives a series of numbers including a called party number, a designated number, and a personal identification number from the telephone 42 or the portable communication terminal 52. The signal processing unit 102 individually acquires a called party number, a designated number, and a personal identification number from the series of numbers.

  The authentication processing unit 103 performs authentication processing of the designated number by collating the designated number and password obtained by the signal processing unit 102 with the telephone number and password of the portable communication terminal 51 registered in the authentication table 230. Do. When the authentication processing is successful, the call processing unit 101 calls the destination number using the designated number as the transmission source number instead of the telephone number corresponding to the transmission source terminal, and when the authentication processing fails, the destination number Stop calling to

  According to the above configuration, when the authentication processing is successful, the communication control servers 1 and 3 call the destination number using the designated number as the source number instead of the telephone number corresponding to the source terminal. As a result, since the designated number is notified to the called telephone 6, even if the user B can not answer for absence, the user B can call the caller by calling back to the designated number.

  Further, when the authentication processing fails, the communication control servers 1 and 3 cancel the call to the destination number. Therefore, for example, it is prevented that a malicious third party makes a call from the telephone 42 or the portable communication terminal 51 to the called telephone 6 using the notification service.

  Therefore, according to the call control system of the embodiment, the convenience of the return transmission is improved.

The call control method according to the embodiment includes the following steps.
Step (1): A series of numbers including the called party number, the designated number, and the personal identification number is received from the telephone set 42 or the portable communication terminal 52 which is the source terminal.
Step (2): The called party number, the designated number and the personal identification number are individually obtained from the series of numbers.
Step (3): The designated number and password obtained are collated with the telephone number and password of the portable communication terminal 51 registered in the authentication table 230 of the contract management server 2 to perform authentication processing of the designated number.
Step (4): When the authentication process is successful, the destination number is called as the source number instead of the telephone number corresponding to the source terminal, and when the authentication process fails, the destination number is used. Stop calling

  Since the call control method according to the embodiment includes the same configuration as the call control system according to the embodiment, the same operation and effect as those described above can be obtained.
