  By the way, when the calling side terminal makes a call with the non notification setting and the called side terminal cannot respond, the telephone number of the calling side terminal is not displayed in the incoming call history of the called side terminal. In such a case, as a matter of course, the user who receives the incoming call cannot make a return call to the calling terminal. However, a user who receives an incoming call with the non-notification setting may be worried about the partner of the missed call or the content of the phone call. On the other hand, the calling terminal does not want to notify the other party of its own phone number, but may want to receive a return call. Therefore, even if the destination terminal receives an incoming call with no notification setting and the telephone number of the calling terminal does not remain in the incoming call history of the destination terminal (it is not displayed), the call is returned from the destination terminal. There is a need for a system that can redial a terminal.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a communication control system and a communication control method capable of improving convenience while ensuring anonymity.

  The receiving unit 601 is a part that receives various types of information from the CSCF 4a. When receiving the transmission request information transmitted from the CSCF 4a, the request reception unit 601 outputs the transmission request information to the determination unit 602. In addition, when receiving the transmission request information transmitted from the CSCF 4b, the receiving unit 601 outputs the transmission request information to the determination unit 602. Further, when receiving the call connection establishment information transmitted from the CSCF 4a, the receiving unit 601 outputs the call connection establishment information to the validity confirmation processing unit 605.

  The determination unit 602 is a part that determines whether the mobile communication terminal 2a is set to not notify the telephone number of its own device. When receiving the transmission request information (CSCF4a transmission) from the reception unit 601, the determination unit 602 determines whether or not non-notification setting information is included in the transmission request information. When determining that the non-notification setting information is included in the transmission request information, that is, the determination unit 602 determines that the non-notification number (184) is included, the ID generation information for instructing generation of a temporary ID is temporarily stored. The data is output to the ID generation unit 603. The ID generation information includes the telephone numbers of the mobile communication terminals 2a and 2b and the restriction information included in the non notification setting information. In addition, when determining that the non-notification setting information is not included in the transmission request information, the determination unit 602 outputs the transmission request information to the transmission unit 608.

  Further, upon receiving the transmission request information (CSCF4b transmission) output from the reception unit 601, the determination unit 602 determines whether or not the transmission request information includes a temporary ID. When determining that the temporary request ID is included in the transmission request information, the determination unit 602 outputs the transmission request information including the number request information to the validity confirmation processing unit 605. On the other hand, when determining that the temporary request ID is not included in the transmission request information, the determination unit 602 outputs the transmission request information to the transmission unit 608.

  The temporary ID generation unit 603 is a part that generates a temporary ID. Upon receiving the ID generation information output from the determination unit 602, the temporary ID generation unit 603 generates a temporary ID according to the ID generation information. Specifically, the temporary ID generation unit 603 generates a unique character string (see FIG. 10), and also includes the telephone number of the mobile communication terminal 2a and the telephone number and restriction information of the mobile communication terminal 2b included in the ID generation information. Is associated with the temporary ID. The temporary ID generation unit 603 outputs the generated temporary ID to the transmission unit 608. Further, the temporary ID generation unit 603 outputs a temporary ID associated with various types of information to the data storage unit 604.

  The data holding unit 604 is a part that stores data including the temporary ID generated by the temporary ID generation unit 603. Upon receiving the temporary ID output from the temporary ID generation unit 603, the data holding unit 604 stores the temporary ID in a table and holds it. FIG. 10 is a diagram illustrating an example of data stored in the data storage unit 604. As shown in the figure, the data holding unit 604 stores “sender”, “receiver”, “temporary ID”, “valid number of times”, and “expiration date” in association with each other. For example, the data holding unit 604 corresponds to the caller “090-2222-AAAA”, the callee “090-1111-AAAA”, the temporary ID “# 1111”, the validity count “3 times”, and the expiration date “none”. Attached and memorized. The data holding unit 604 updates the data when the temporary ID is output from the temporary ID generation unit 603 or when the temporary ID is deleted by the ID deletion unit 607. In the data in the data holding unit 604, “sender”, “receiver”, and “temporary ID” are basic information, and “valid count” and “expiration date” are additional information (restriction information).

  The validity confirmation processing unit 605 is a part for confirming the validity of the temporary ID. When the validity check processing unit 605 receives the call request information output from the determination unit 602, the validity check processing unit 605 restricts information (return information, number of times information, and time limit) associated with the temporary ID included in the number request information of the call request information. Information) is checked for validity. Specifically, when receiving the number request information, the validity confirmation processing unit 605 refers to the data storage unit 604 based on the temporary ID. Then, the validity confirmation processing unit 605 extracts the “valid number” corresponding to the temporary ID, and determines whether the number of times the temporary ID is received does not exceed the “valid number”. In addition, the validity check processing unit 605 extracts an “expiration date” corresponding to the temporary ID, and determines whether the date and time when the temporary ID is received does not exceed the “expiration date”. If the determination result is OK, the validity confirmation processing unit 605 outputs confirmation information indicating that to the number conversion unit 606. In addition, when the determination result is NG, the validity confirmation processing unit 605 outputs interruption information for interrupting the call connection to the control unit (not shown) and deletes the instruction to delete the corresponding temporary ID. Information is output to the ID deletion unit 607.

  In addition, when the validity confirmation processing unit 605 receives call connection establishment information from the reception unit 601, the validity confirmation processing unit 605 updates the number of validity (limit information) in the data holding unit 604. Specifically, the validity check processing unit 605 refers to the data holding unit 604 based on the profiles of the mobile communication terminals 2a and 2b included in the call connection establishment information, and displays “valid” of the temporary ID corresponding to the profile. Subtract "number of times". That is, when the “effective number” is “3 times”, for example, it is set to “2 times”. At this time, when the “valid number” becomes “0”, the validity confirmation processing unit 605 outputs deletion information for instructing deletion of the information of the corresponding temporary ID to the ID deletion unit 607.

  The number conversion unit 606 is a part that converts the temporary ID into a telephone number. Upon receiving the confirmation information output from the validity confirmation processing unit 605, the number conversion unit 606 refers to the data holding unit 604, extracts the telephone number of the “caller” associated with the temporary ID, and temporarily stores it. The ID is converted to the phone number of the “sender”. The number conversion unit 606 outputs number information indicating the converted telephone number to the transmission unit 608.

  The ID deletion unit 607 is a part for deleting a temporary ID. Upon receiving the deletion information output from the validity check processing unit 605, the ID deletion unit 607 deletes the temporary ID corresponding to the deletion information from the data holding unit 604.

  The transmission unit 608 is a part that transmits various types of information to the CSCFs 4a and 4b. Upon receiving the transmission request information output from the determination unit 602, the transmission unit 608 transmits this transmission request information to the CSCF 4a. In addition, when receiving the number information output from the number conversion unit 606, the transmission unit 608 transmits call request information including the number information to the CSCF 4b. In addition, when receiving transmission request information from the reception unit 601, the transmission unit 608 transmits the transmission request information to the CSCF 4b.

  11 and 12 are sequence diagrams showing processing (communication control method) in the communication control system 1. FIG. 13 is a flowchart showing validity check processing in the ID management device 6. When these processes are transmitted from the mobile communication terminal 2a to the mobile communication terminal 2b, the mobile communication terminal 2b does not respond, and is then returned from the mobile communication terminal 2b to the mobile communication terminal 2a to establish a call. This is the process until

  As shown in FIG. 11, first, in response to a request for transmission from the mobile communication terminal 2a to the mobile communication terminal 2b, transmission request information is transmitted from the transmission request transmission unit 202 of the mobile communication terminal 2a to the CSCF 4a (step S01). . When the call request information is received by the call request receiving unit 401 of the CSCF 4a, the call request information is transmitted from the request transmitting unit 402 of the CSCF 4a to the ID management device 6 (step S02).

  Next, when the transmission request information transmitted from the request transmission unit 402 of the CSCF 4a is received by the reception unit 601 of the ID management device 6, the determination unit 602 of the ID management device 6 determines whether or not to generate a temporary ID. That is, it is determined whether or not non-notification setting information is included in the transmission request information (step S03). If it is determined that the non-notification setting information is included in the transmission request information, the process proceeds to step SS04. On the other hand, if it is determined that the non-notification setting information is not included in the transmission request information, the process proceeds to step S05.

  In step S 04, a temporary ID is generated by the temporary ID generation unit 603 of the ID management device 6 and the temporary ID is held in the data holding unit 604. Then, transmission request information including the generated temporary ID is transmitted from the transmission unit 608 of the ID management device 6 to the CSCF 4a (step S05).

  Subsequently, when the transmission request information transmitted from the transmission unit 608 of the ID management device 6 is received by the temporary ID reception unit 403 of the CSCF 4a, the transmission request information is transmitted from the transmission request transmission unit 405 of the CSCF 4a to the CSCF 4b. (Step S06). When the call request information is received by the call request receiving unit 407 of the CSCF 4b, the telephone number of the mobile communication terminal 2a in the temporary ID included in the call request information is discarded by the number discarding unit 408, and the mobile communication terminal The call request information that does not include the telephone number 2a is transmitted from the call request transmission unit 409 of the CSCF 4b to the mobile communication terminal 2b (step S07). Then, in the mobile communication terminal 2b that has received the call request information transmitted from the call request transmitting unit 409 of the CSCF 4b by the call request receiving unit 205, the control unit performs incoming call control. At this time, the mobile communication terminal 2b makes no response to the incoming call (step S08).

  Subsequently, as shown in FIG. 12, the return call request information is transmitted from the return call request transmission unit 207 of the mobile communication terminal 2b to the CSCF 4b in response to a call request addressed to the temporary ID (step S09). When the return call request information is received by the return call request receiving unit 410 of the CSCF 4b, the call request information is transmitted from the number request unit 411 of the CSCF 4b to the ID management device 6 (step 10).

  Next, when the call request information transmitted from the number request unit 411 of the CSCF 4b is received by the receiving unit 601 of the ID management device 6, the validity checking process is performed by the determining unit 602 and the validity checking processing unit 605. (Step S11). The validity check process will be described with reference to FIG.

  As shown in FIG. 13, when the validity check process is performed, first, the determination unit 602 determines whether or not the transmission request information includes a temporary ID (presence / absence of a temporary ID) (step S21). If it is determined that the temporary ID is included, the process proceeds to step S22. On the other hand, when it is determined that the temporary ID is not included, normal transmission control is executed.

  In step S22, the validity confirmation unit 605 determines whether or not the temporary ID is valid based on the return information. If it is determined that the temporary ID is valid, the process proceeds to step S23. On the other hand, when it is determined that the temporary ID is not valid, call connection interruption processing is executed as a call failure.

  In step S23, the validity confirmation unit 605 determines whether or not the temporary ID is within the valid number based on the number information. If it is determined that the number is within the effective number, the process proceeds to step S24. On the other hand, when it is determined that the number is not within the valid number, the call connection interruption process is executed as a call failure.

  In step S24, the validity checking unit 605 determines whether or not the temporary ID is within the expiration date based on the expiration date information. If it is determined that it is within the expiration date, the temporary ID is converted into the telephone number of the mobile communication terminal 2a by the number conversion unit 606 based on the temporary ID (step S25). On the other hand, if it is determined that it is not within the expiration date, call connection interruption processing is executed as a call failure. As described above, the validity check process is performed.

  Returning to FIG. 12, when the validity check process is performed as described above, the transmission request information including the number information is transmitted from the transmission unit 608 of the ID management device 6 to the CSCF 4b (step S12). When the call request information is received by the number receiving unit 412 of the CSCF 4b, the call request information is transmitted from the return call request transmitting unit 414 of the CSCF 4b to the CSCF 4a (step S13), and the call request information is transmitted by the CSCF 4a. The data is transmitted from the unit 405 to the mobile communication terminal 2a (step S14). When the mobile communication terminal 2a receives the call request information by the call request receiving unit 203 and makes a response to the incoming call according to the call request information (step S15), the response unit 204 of the mobile communication terminal 2a responds to the CSCF 4a. Information is transmitted (step S16). When this response information is received by the call connection establishment unit 406 of the CSCF 4a, the call connection establishment unit 406 of the CSCF 4a establishes a call connection between the mobile communication terminal 2a and the mobile communication terminal 2b (step S17).

  Then, in response to establishment of the call connection between the mobile communication terminal 2a and the mobile communication terminal 2b, call connection completion information (communication establishment notification) is transmitted from the call connection establishment unit 406 of the CSCF 4a to the ID management device 6 (step S18). The validity check processing unit 605 of the ID management device 6 that has received this call connection completion information updates the number of validity of the temporary ID (step S19).

  When the mobile communication terminal 2b responds to the incoming call in step S08, response information is transmitted from the mobile communication terminal 2b to the CSCF 4b, and the CSCF 4b that receives the response information receives the response information between the mobile communication terminal 2a and the mobile communication terminal 2b. Call connection establishment processing is executed. In response to the establishment of the call connection, call connection establishment information indicating that fact is transmitted from the CSCF 4b to the ID management device 6. As a result, the temporary ID corresponding to the call connection establishment information is deleted in the ID management device 6.

  As described above, in the communication control system 1, when the call request information includes non notification setting information when the call is transmitted from the mobile communication terminal 2a to the mobile communication terminal 2b, the telephone of the mobile communication terminal 2a is used. A temporary ID generating unit 603 of the ID management device 6 generates a temporary ID that allows the number to be uniquely specified, and based on the temporary ID, call request information that does not include the telephone number of the mobile communication terminal 2a is sent back to the CSCF 4b. The transmission part 414 produces | generates and transmits this transmission request information to the mobile communication terminal 2b. Then, when the loopback transmission request transmission unit 207 of the mobile communication terminal 2b transmits the temporary ID from the missed call history as the destination, the ID management device 6 refers to the data holding unit 605 based on the temporary ID, and the mobile communication terminal 2a A telephone number is acquired, and transmission request information is transmitted from the transmission request transmission unit 405 of the CSCF 4a to the mobile communication terminal 2a. Accordingly, in the mobile communication terminal 2b, when the incoming call is received from the mobile communication terminal 2a with the non-notification setting, the mobile communication terminal 2b does not know the telephone number of the mobile communication terminal 2a but the mobile communication terminal 2b based on the temporary ID. Since the telephone number 2a is acquired and the call request information is transmitted from the CSCF 4a to the mobile communication terminal 2a, it is possible to make a return call to the mobile communication terminal 2a by making a call to the temporary ID. Further, the mobile communication terminal 2a can receive a return call without notifying the mobile communication terminal 2b of its own telephone number. Therefore, it is possible to improve convenience while ensuring anonymity.

  In the present embodiment, the non notification setting information further includes restriction information for restricting transmission from the mobile communication terminal 2b to the mobile communication terminal 2a, and the return call request receiving unit 410 returns the return call request. When the information is received and the validity of the restriction information that confirms the validity of the restriction information included in the non-notification setting information is confirmed, the number conversion unit 606 assigns the temporary ID to the mobile communication terminal. 2a is converted to the telephone number 2a, the return call from the mobile communication terminal 2b to the mobile communication terminal 2a is restricted. For example, when the effective number of return calls is limited to one in the restriction information, the mobile communication terminal The return call from 2b to the mobile communication terminal 2a is limited to one time. Thereby, since it is possible to prevent the outgoing call from being made more than necessary, the convenience can be further improved.

  Further, in the return call from the mobile communication terminal 2b to the mobile communication terminal 2b, when the call connection between the mobile communication terminal 2a and the mobile communication terminal 2b is established, the restriction information (number of times information) is the validity confirmation processing unit 605. Therefore, it is possible to prevent the return call from the second mobile communication to the first mobile communication terminal from being performed more than necessary. Therefore, the convenience can be further improved.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the non-notification setting information includes restriction information (turnback information, number-of-times information, and time limit information), but the restriction information is not necessarily included.

  In the above embodiment, when the call connection establishment unit 406 establishes a call connection between the mobile communication terminal 2a and the mobile communication terminal 2b, the temporary ID valid count is updated. However, the temporary ID update is performed. Is not limited to the above method. For example, as shown in FIG. 14, when “non-notification transmission ID deletion” of “setting change after transmission” is selected in the mobile communication terminal 2a, deletion information instructing deletion of the temporary ID is transmitted to the CSCF 4a, Then, deletion information may be transmitted from the CSCF 4 a to the ID management device 6, and the temporary ID may be deleted by the ID deletion unit 607 of the ID management device 6.

  In addition to the above embodiment, the restriction information included in the non-notification setting information may be configured such that the setting can be changed not only at the time of transmission but also after transmission. For example, as shown in FIG. 14, when “changing the number of times of return” of “setting change after calling” is selected in the mobile communication terminal 2 a after making a call to the mobile communication terminal 2 b, a pull-down menu is displayed. Change the number of times. Thereby, the effective number of return transmissions can be changed even after transmission.
