1-5. Operation Next, the operation of the communication system 9 will be described. The operation of the communication system 9 is divided into an operation at the registration stage and an operation at the call stage. In the following, it is assumed that the terminal 2a is a calling terminal 2 and the terminal 2b is a receiving terminal 2.
(1) Registration stage The management organization of the server apparatus 1 accepts an application for registration of certification information from the user of the terminal 2a. The application may be made by mail or electronic application via the Internet or the like. The operator of the management organization examines the contents of the received application and confirms that the application contents are not false. Then, the operator operates the registration terminal 4 to transmit the application contents to the server device 1. The server device 1 creates certification information according to the contents of the transmitted application, and stores it in the certification DB 121 in association with the telephone number assigned to the terminal 2a. Thereby, it is guaranteed that only the certification information authenticated by the management organization is stored in the certification DB 121.

  The management organization of the server device 1 accepts an application for registration of incoming call rejection from the user of the terminal 2b. The operator of the management organization operates the registration terminal 4 to transmit the application content to the server device 1. Thereby, the incoming call rejection DB 122 stores the incoming call rejection setting for the terminal 2b. The registration of the call rejection setting may not be performed via the registration terminal 4. For example, the control unit 11 of the server device 1 registers in response to a request sent from the terminal 2 b via the communication network 3. May be.

(2) Call Stage FIG. 8 is a flowchart for explaining the operation of the server device 1 in the call stage of the communication system 9. As shown in FIG. 8, the control unit 11 of the server device 1 determines whether or not a call for requesting a call from the terminal 2a to the terminal 2b has been detected (step S101). While transmission is not detected (step S101; NO), the control unit 11 continues the determination in step S101. When a call is detected (step S101; YES), the control unit 11 extracts a call telephone number from the content of the call, and searches the certification DB 121 for certification information corresponding to the extracted call telephone number (step S102). Then, it is determined whether or not the above-mentioned certification information exists in the certification DB 121 (step S103).

  When it is determined that there is certification information, that is, when certification information is specified (step S103; YES), the control unit 11 transmits the certification information to the terminal 2b on the receiving side (step S104), and extracts the outgoing call The number is transmitted to the terminal 2b on the receiving side (step S106). When it is determined that there is no proof information, that is, when proof information is not specified (step S103; NO), the control unit 11 extracts the incoming telephone number that is the telephone number of the terminal 2b from the content of the above-described transmission, It is determined by referring to the incoming call rejection DB 122 whether there is an incoming call rejection setting associated with this incoming telephone number (step S105).

  If it is determined that there is an incoming call rejection setting (step S105; YES), the control unit 11 ends the process. On the other hand, when it determines with there being no setting of a call rejection (step S105; NO), the control part 11 advances a process to step S106 mentioned above. When the calling telephone number is transmitted to the terminal 2b in step S106, the control unit 11 determines whether or not a response from the terminal 2b is detected (step S107). If it is determined that a response has been detected (step S107; YES), the control unit 11 connects the terminal 2a and the terminal 2b through a speech path (step S108). When it determines with a response not being detected (step S107; NO), the control part 11 complete | finishes a process.

  FIG. 9 is a flowchart for explaining the operation of the terminal 2 b in the communication stage of the communication system 9. As shown in FIG. 9, the control unit 21 of the terminal 2b determines whether or not there is an input of transmission using the operation unit 24 by the user (step S201), and when it is determined that there is an input (step S201). S201; YES), a call is made according to the input content (step S208).

  On the other hand, when it determines with there being no input (step S201; NO), the control part 21 determines whether the transmission telephone number was received from the server apparatus 1 (step S202). And when it determines with not having received the calling telephone number (step S202; NO), the control part 21 returns a process to determination of step S201. When it determines with having received the calling telephone number (step S202; YES), the control part 21 displays the received calling telephone number on the display part 25 (step S203).

The control unit 21 determines whether certification information has been received from the server device 1 (step S204). When it determines with having received certification information from the server apparatus 1 (step S204; YES), the control part 21 displays the content of the received certification information on the display part 25 (step S205), and advances a process to step S206. .
On the other hand, when it determines with not receiving certification information from the server apparatus 1 (step S204; NO), the control part 21 advances a process directly to step S206.

  In step S206, the control unit 21 determines whether or not an operation for responding to a call request from the terminal 2a to which the received outgoing telephone number is assigned has been input by the operation unit 24 of the terminal 2b (step S206). . If it is determined that there is a response input (step S206; YES), the control unit 21 transmits a signal indicating this response to the server device 1 (step S207). On the other hand, if it is determined that there is no response input, the control unit 21 ends the process. The control unit 21 displays the calling telephone number on the display unit 25 in step S203, and displays the contents of the certification information on the display unit 25 in step S205. However, these may be performed simultaneously or in order. The reverse may be possible. For example, when it is determined in step S202 that the calling telephone number has been received, the control unit 21 determines whether or not the certification information has been received from the server device 1 in step S204 without performing step S203. And when it determines with having received certification information from the server apparatus 1 (step S204; YES), the control part 21 displays the content of the received transmission telephone number and certification information on the display part 25 (step S203, S205). ), The process proceeds to step S206. On the other hand, when it determines with not having received certification information from the server apparatus 1 (step S204; NO), the control part 21 displays only the received transmission telephone number on the display part 25 (step S203), and then step What is necessary is just to advance a process to S206.

  FIG. 10 is a sequence diagram showing the operation of the communication system 9 when the originating terminal 2a whose certification information is registered in the certification DB 121 of the server device 1 tries to make a call to the terminating terminal 2b. When the terminal 2a makes a call by designating the telephone number of the terminal 2b (step S301), the control unit 11 of the server device 1 detects the call (step S302). Then, the server device 1 extracts the outgoing telephone number that is the telephone number of the terminal 2a from the detected content of the outgoing call, and searches the certification DB 121 of the storage unit 12 for certification information corresponding to this outgoing telephone number (step S303). Then, the presence / absence of certification information is determined (step S304). Then, the server device 1 extracts the incoming telephone number that is the telephone number of the terminal 2b from the detected content of the outgoing call, and sends the outgoing telephone number to the terminal 2b based on the incoming telephone number and the result of the search described above. The above-described certification information specified from the certification DB 121 is transmitted (step S305).

  When the terminal 2b receives the outgoing telephone number transmitted from the server device 1, the terminal 2b causes the display unit 25 to display the corresponding telephone number (step S306). The user of the terminal 2b confirms the identity of the user of the terminal 2a by looking at the display of the contents of the certification information, and when he / she thinks that he / she can respond, he / she operates the operation unit 24 of the terminal 2b to instruct a response. Upon receiving this response, the terminal 2b sends a signal indicating this response to the server device 1 (step S307). When the server apparatus 1 receives a signal indicating a response from the terminal 2b, the server apparatus 1 connects the terminal 2a and the terminal 2b through a speech path (step S308).

  When the control unit 21 of the terminal 2b receives only the outgoing phone number without the certification information, the control unit 21 searches the name table 221 for the name corresponding to the transmitted outgoing phone number, and when the name is specified. May display the specified name on the display unit 25. Further, the control unit 21 of the terminal 2b may reject the incoming call when the name is not specified.

  FIG. 11 is a diagram illustrating an example of an image displayed on the display unit 25 of the terminal 2b when the certification information is received. When the terminal 2b receives the outgoing telephone number and the certification information, the display unit 25 displays the content of the certification information corresponding to the outgoing telephone number together with the outgoing telephone number, as shown in FIG. On the assumption that the user of the terminal 2b has been authenticated by the management organization of the server device 1, the user examines the certification information and determines whether or not to respond to the call request. The contents described in the certification information are reliable for the user, and when the user responds to the request for the call, the server device 1 detects this response and connects the terminal 2a and the terminal 2b through the communication path.

  As described above, in the communication system 9, the server apparatus 1 has the certification DB 121 that stores the telephone number assigned to the terminal 2 and the certification information that proves the identity of the user of the terminal 2 in association with each other. Yes. When the server device 1 detects a call originating from the terminal 2, the server device 1 transmits certification information associated with the telephone number of the terminal 2 to the terminal 2 on the receiving side. Even if the telephone number of the terminal 2 on the calling side is not registered in the number table 221, it can be determined whether or not to answer the telephone by checking the certification information.

2. Modification The above is the description of the embodiment, but the contents of this embodiment can be modified as follows. Further, the following modifications may be combined.
2-1. Receiving Rejection In the embodiment described above, the storage unit 12 of the server device 1 has the incoming call rejection DB 122, but may not have the incoming call rejection DB 122. In this case, the server device 1 detects the outgoing call from the terminal 2, and if the certification information corresponding to the outgoing telephone number of the terminal 2 is not stored in the certification DB 121, the server apparatus 1 rejects the incoming call by terminating the process. Also good.

2-2. Identification Information of Server Device In the above-described embodiment, the communication system 9 has one server device 1, but a plurality of server devices 1 may be provided. In this case, each of the plurality of server devices 1 stores identification information for identifying itself from the other server devices 1 in the storage unit 12, and when transmitting certification information to the terminal 2, identification information indicating itself is respectively stored. You may make it transmit to the terminal 2. FIG. Thereby, the user of the terminal 2 that has received the proof information confirms by which server device 1 the proof information is authenticated, and determines whether or not to respond to the call request. Can do.

2-3. Network Device In the above-described embodiment, the server device 1 provides the receiving terminal 2 with proof information that proves the identity of the calling terminal 2, as well as the formation of the communication path and the detection of the end of the call from the detection of the outgoing call. Although a series of processing for realizing a call such as opening a call path has been performed, the function of these exchanges may not be provided. In this case, the communication system 9 may include a network device 5 that realizes the functions of these exchanges.

  FIG. 12 is a diagram showing a configuration of the communication system 9 in this modification. In this modification, the communication system 9 is different from the above-described embodiment in that the communication system 9 includes the network device 5, and part of the functions of the server device 1 in the embodiment is realized by the network device 5. This is the point.

  FIG. 13 is a diagram illustrating a configuration of the network device 5. The network device 5 includes a control unit 51, a storage unit 52, and a communication unit 53. The control unit 51 includes a CPU, a ROM, and a RAM, and the CPU controls each unit of the network device 5 by reading the boot loader stored in the ROM and the program stored in the storage unit 52 into the RAM and executing the program. . The storage unit 52 is a large-capacity storage unit such as a hard disk drive, and stores a program read by the control unit 51. The communication unit 53 is a circuit that communicates with the communication network 3.

  FIG. 14 is a diagram illustrating a functional configuration of the network device 5 and the server device 1. The control unit 51 of the network device 5 functions as a detection unit 511, a request unit 512, an acquisition unit 513, and a connection unit 514. The control unit 11 of the server device 1 functions as the specifying unit 112 and the determination unit 113. In addition, illustration is abbreviate | omitted about the communication part 53 and the communication part 13 which communicate with the network apparatus 5 and the server apparatus 1. FIG.

  The detection unit 511 of the network device 5 monitors the terminal 2 connected to the communication network 3 and detects the transmission when any of the terminals 2 makes a call. When the detecting unit 511 detects a call from the terminal 2, the request unit 512 extracts the calling telephone number and the incoming telephone number from the content of the outgoing call, and obtains the certification information corresponding to the outgoing telephone number and the incoming telephone number. The server apparatus 1 is requested to set the corresponding incoming call rejection.

The specifying unit 112 of the server device 1 attempts to specify the certification information requested by the request unit 512 from the certification DB 121 of the storage unit 12.
The determination unit 113 transmits a request signal for requesting a call to the terminal 2 on the receiving side to the network device 5 when the specifying unit 112 specifies the certification information described above. Further, the determination unit 113 searches the incoming call rejection DB 122 in the storage unit 12 when the specifying unit 112 does not specify the proof information described above, and the setting of incoming call rejection corresponding to the incoming telephone number is “Yes”. It is determined whether it is “not” or not. If the determination unit 113 determines that the setting for rejecting an incoming call is “No”, the determination unit 113 transmits a request signal for requesting a call to the terminal 2 on the receiving side to the network device 5.

  Note that if the determination unit 113 determines that the specifying unit 112 has not specified the certification information and the setting of the incoming call rejection corresponding to the incoming telephone number is “Yes”, the determination unit 113 goes to the network device 5. Is not sent. As a result, regarding the above call, the incoming call rejection at the terminal 2 to which the incoming telephone number is assigned is performed by the network device 5 before the call path is formed.

  The acquisition unit 513 of the network device 5 receives the request signal described above from the server device 1. When the acquisition unit 513 receives the request signal and detects a response from the terminal 2 on the incoming side, the connection unit 514 connects the telephone line between the terminal 2 on the outgoing side and the terminal 2 on the incoming side to establish a call.

  FIG. 15 is a sequence diagram showing an example of the operation of the communication system 9 in this modification. The processes common to the processes described in FIG. Here, the operation of the communication system 9 when the originating terminal 2a whose certification information is registered in the certification DB 121 of the server device 1 tries to make a call to the terminating terminal 2b will be described.

  When the terminal 2a makes a call by designating the telephone number of the terminal 2b (step S301), the control unit 51 of the network device 5 detects the call (step S302). Then, the network device 5 extracts the outgoing telephone number that is the telephone number of the terminal 2a from the detected content of the outgoing call, and requests the server device 1 for certification information corresponding to this outgoing telephone number (step S401). The control unit 11 of the server device 1 searches the certification DB 121 in the storage unit 12 (step S303) and determines whether there is certification information requested by the network device 5 (step S304). And the control part 11 of the server apparatus 1 transmits the certification | authentication information specified by search to the network apparatus 5, and the network apparatus 5 acquires this (step S402).

  The network device 5 extracts the incoming telephone number that is the telephone number of the terminal 2b from the detected content of the outgoing call, and transmits the outgoing telephone number and the acquired certification information to the terminal 2b based on the incoming telephone number. (Step S305).

  When the terminal 2b receives the outgoing telephone number transmitted from the network device 5, the terminal 2b causes the display unit 25 to perform a display corresponding to the telephone number (step S306). The user of the terminal 2b confirms the identity of the user of the terminal 2a by looking at the display of the contents of the certification information, and when he / she thinks that he / she can respond, he / she operates the operation unit 24 of the terminal 2b to give a response. Upon receiving this response, the terminal 2b sends a signal indicating this response to the network device 5 (step S307). When the network device 5 receives a signal indicating a response from the terminal 2b, the network device 5 connects the terminal 2a and the terminal 2b through a speech path (step S308).

  With this configuration, the function of providing certification information and the function of an exchange that connects the terminals 2 with each other through a communication path are separated, so that each load on the server device 1 and the network device 5 is reduced.

2-4. Interface The interface 14 of the server device 1 described above may be an interface for exchanging data other than the above-described standards, and the server device 1 and the registration terminal 4 are connected via the interface 14 via a LAN (Local Area Network), the Internet, or a wide area dedicated line.

  Moreover, although the server apparatus 1 mentioned above was the structure connected with the registration terminal 4, it connects with input devices, such as a keyboard which receives the application for registration of certification information from the user of the terminal 2, and the application of the application is via this. If the certification information corresponding to the content is stored in the certification DB 121 in association with the telephone number assigned to the terminal 2, it is not necessary to connect to the registration terminal 4. In this case, the interface 14 may be, for example, a serial interface that conforms to the USB standard if the input device described above conforms to the USB (Universal Serial Bus) standard.

2-5. Each program executed by the control unit 11 of the program server device 1 and the control unit 21 of the terminal 2 is a magnetic recording medium such as a magnetic tape or a magnetic disk, an optical recording medium such as an optical disk, a magneto-optical recording medium, a semiconductor memory, or the like. It can be provided in a state of being stored in a recording medium readable by a computer device. It is also possible to download this program via a network such as the Internet. Note that various devices other than the CPU may be applied as the control means exemplified by the control unit 11 or the control unit 21 described above. For example, a dedicated processor or the like is used.

2-6. Notification The terminal 2 (terminal 2b) described above notifies the user of the received outgoing telephone number and certification information by displaying them on the display unit 25. May be notified. That is, the display of information by the display unit 25 is an aspect of information notification. For example, when the calling telephone number or the certification information is text information, it may be notified to the user by converting them into voice and reading them out. In addition, the calling telephone number or the certification information may be a voice signal representing voice, and the terminal 2 that has received these voice signals emits a sound according to the voice signal, so that the calling telephone number or the certification information is obtained. May be notified to the user.
