　セッション制御サーバ１は、電話網６を介して発信者電話機４及び受信者電話機５を含む複数の電話機に接続されている。セッション制御サーバ１は、呼接続制御部１１と、シナリオ読込部１２と、撃退情報出力部１３と、を含む。 The session control server 1 is connected to a plurality of telephones including the caller telephone 4 and the receiver telephone 5 via the telephone network 6. The session control server 1 includes a call connection control unit 11, a scenario reading unit 12, and a repulsion information output unit 13.
　呼接続制御部１１は、発信者電話機４による発呼があったとき、この発信者電話機４の電話番号が電話番号記録部２２（詳細は後述）に記録されていない場合には、受信者電話機５に呼を接続する。呼接続制御部１１はまた、判定部２１（詳細は後述）にて発信者電話機４の電話番号が電話番号記録部２２に記録されていると判定された際に、発信者電話機４による発呼が迷惑電話の可能性があることを受信者電話機５に通知する。呼が接続されることにより、例えば、発信者電話機４と受信者電話機５の間で音声による通話が可能となる。 When the call connection control unit 11 makes a call by the caller telephone 4, if the telephone number of the caller telephone 4 is not recorded in the telephone number recording unit 22 (details will be described later), the call connection control unit 11 is the receiver telephone. Connect the call to 5. The call connection control unit 11 also makes a call by the caller telephone 4 when the determination unit 21 (details will be described later) determines that the telephone number of the caller telephone 4 is recorded in the telephone number recording unit 22. Notifies the receiver telephone 5 that there is a possibility of a nuisance call. By connecting the call, for example, a voice call can be made between the caller telephone 4 and the receiver telephone 5.
　シナリオ読込部１２は、発信者電話機４より発呼があった際に、ＡＰＬサーバ２のプログラムメモリ２６（詳細は後述）に記憶されている呼制御シナリオを読み込む。上述した呼接続制御部１１は、シナリオ読込部１２により読み込まれた呼制御プログラムに基づいて呼の接続を実行する。 The scenario reading unit 12 reads the call control scenario stored in the program memory 26 (details will be described later) of the APL server 2 when a call is made from the caller telephone 4. The call connection control unit 11 described above executes a call connection based on the call control program read by the scenario reading unit 12.
　撃退情報出力部１３は、ＡＰＬサーバ２より出力される音声データを取得し、この音声データを所望の電話機に出力する。例えば、発信者による通話が迷惑電話であるか或いは迷惑電話の可能性が高い場合に、この発信者の発信者電話機４に撃退用の音声データを出力する。 The repulsion information output unit 13 acquires the voice data output from the APL server 2 and outputs this voice data to a desired telephone. For example, when the call made by the caller is a nuisance call or the possibility of a nuisance call is high, voice data for repulsion is output to the caller telephone 4 of the caller.
　撃退情報出力部１３はまた、後述する判定部２１より、発信者電話機４による発呼が迷惑電話である可能性があると判定された場合には、受信者電話機５に対して、迷惑電話の可能性がある旨の内容を通知する。例えば、発信者電話機４の電話番号が、過去に複数回迷惑電話が発呼された電話番号である場合には、発信者電話機４と受信者電話機５との間で呼を接続する前に、迷惑電話の可能性があることを受信者に知らせる。 When the determination unit 21, which will be described later, determines that the call made by the caller telephone 4 may be a nuisance call, the repulsion information output unit 13 also makes a nuisance call to the receiver telephone 5. Notify the content that there is a possibility. For example, if the telephone number of the caller telephone 4 is a telephone number for which a nuisance call has been made a plurality of times in the past, before connecting the call between the caller telephone 4 and the receiver telephone 5. Inform the recipient that there is a possibility of a nuisance call.
　ＡＰＬサーバ２は、判定部２１と、電話番号記録部２２と、撃退操作受付部２３と、音声データ作成部２４と、撃退指令出力部２５と、プログラムメモリ２６と、を含む。 The APL server 2 includes a determination unit 21, a telephone number recording unit 22, a repulsion operation reception unit 23, a voice data creation unit 24, a repulsion command output unit 25, and a program memory 26.
　電話番号記録部２２は、過去に迷惑電話が発呼された電話機の電話番号を記録する。即ち、電話番号記録部２２は、受信者電話機５により撃退操作が入力された発信者電話機４の電話番号を記録する。 The telephone number recording unit 22 records the telephone number of the telephone to which the nuisance call was called in the past. That is, the telephone number recording unit 22 records the telephone number of the caller telephone 4 to which the repulsion operation is input by the receiver telephone 5.
　判定部２１は、発信者電話機４による発呼があった際に、発信者電話機４の電話番号が電話番号記録部２２に記録されているか否かを判定する。判定部２１はまた、発信元となる電話機に対して、撃退操作が所定回数（後述する「既定値」）入力された際に、この電話機の電話番号を電話番号記録部２２に記録する。 The determination unit 21 determines whether or not the telephone number of the caller telephone 4 is recorded in the telephone number recording unit 22 when the call is made by the caller telephone 4. The determination unit 21 also records the telephone number of the telephone in the telephone number recording unit 22 when the repulsion operation is input to the telephone as the caller a predetermined number of times (“default value” described later).
　撃退操作受付部２３は、発信者電話機４と受信者電話機５との間で呼が接続されている際に、受信者による撃退操作の入力を受け付ける。例えば、発信者と受信者との通話が行われている際に、受信者がこの通話が特殊詐欺などの迷惑電話であると判断した場合には、例えば専用の操作スイッチを押すなどの撃退操作を行うと、この操作入力が撃退操作受付部２３にて取得される。 The repulsion operation reception unit 23 receives the input of the repulsion operation by the receiver when the call is connected between the caller telephone 4 and the receiver telephone 5. For example, when a call is being made between the sender and the receiver, if the receiver determines that the call is a nuisance call such as a special fraud, a repulsion operation such as pressing a dedicated operation switch is performed. Then, this operation input is acquired by the repulsion operation reception unit 23.
　撃退指令出力部２５は、受信者電話機５にて撃退操作が入力され、撃退操作受付部２３にて撃退操作の入力が検出された際に、ＴＴＳサーバ３に撃退指令信号を出力する。 The repulsion command output unit 25 outputs a repulsion command signal to the TTS server 3 when the repulsion operation is input by the receiver telephone 5 and the input of the repulsion operation is detected by the repulsion operation reception unit 23.
　音声データ作成部２４は、ＴＴＳサーバ３より出力された撃退用のテキストデータを音声データに変換し、セッション制御サーバ１に出力する。 The voice data creation unit 24 converts the text data for repulsion output from the TTS server 3 into voice data and outputs it to the session control server 1.
　プログラムメモリ２６には、発信者電話機４による発呼、及び受信者電話機５での着呼を制御するための呼制御シナリオが記憶されている。また、迷惑電話撃退用のアプリケーションが記憶されている。 The program memory 26 stores a call control scenario for controlling the outgoing call by the calling telephone 4 and the incoming call by the receiving telephone 5. Also, an application for repelling nuisance calls is stored.
　ＴＴＳサーバ３は、迷惑電話を撃退するための撃退メッセージのテキストデータを記憶している。ＴＴＳサーバ３は、ＡＰＬサーバ２より撃退指令信号が入力された際に、撃退メッセージを迷惑電話の発信元となる発信者電話機４に出力する。即ち、ＴＴＳサーバ３は、受信者電話機５にて撃退操作が入力された際に、発信者電話機４に対して撃退処理を行う撃退処理部としての機能を備えている。 The TTS server 3 stores the text data of the repulsion message for repelling the nuisance call. When the repulsion command signal is input from the APL server 2, the TTS server 3 outputs the repulsion message to the caller telephone 4 which is the source of the nuisance call. That is, the TTS server 3 has a function as a repulsion processing unit that performs repulsion processing on the caller telephone 4 when a repulsion operation is input on the receiver telephone 5.
　［第１実施形態の動作］
　次に、第１実施形態の動作について説明する。図２は、第１実施形態に係る迷惑電話防止システム１０１の処理手順を示すフローチャートである。 [Operation of the first embodiment]
Next, the operation of the first embodiment will be described. FIG. 2 is a flowchart showing a processing procedure of the nuisance call prevention system 101 according to the first embodiment.
　初めに、図２に示すステップＳ１１において発信者電話機４にて発信者による発呼が行われる。 First, in step S11 shown in FIG. 2, the caller makes a call on the caller telephone 4.
　ステップＳ１２において、判定部２１は、発信者電話機４の電話番号が電話番号記録部２２に記録されているか否かを判定する。記録されている場合には（Ｓ１２；ＹＥＳ）、ステップＳ１７に処理を進め、そうでなければ（Ｓ１２；ＮＯ）、ステップＳ１３に処理を進める。 In step S12, the determination unit 21 determines whether or not the telephone number of the caller telephone 4 is recorded in the telephone number recording unit 22. If it is recorded (S12; YES), the process proceeds to step S17, otherwise (S12; NO), the process proceeds to step S13.
　初期的には、発信者電話機４の電話番号は電話番号記録部２２に記録されていないので、ステップＳ１３において、セッション制御サーバ１のシナリオ読込部１２は、プログラムメモリ２６に記憶されている呼制御シナリオを読み込む。呼接続制御部１１は、呼制御シナリオに基づき、発信者電話機４と受信者電話機５との間で呼を接続する。その結果、発信者電話機４と受信者電話機５との間での音声通話が可能となる。 Initially, the telephone number of the caller telephone 4 is not recorded in the telephone number recording unit 22, so that in step S13, the scenario reading unit 12 of the session control server 1 performs call control stored in the program memory 26. Load the scenario. The call connection control unit 11 connects a call between the caller telephone 4 and the receiver telephone 5 based on the call control scenario. As a result, a voice call can be made between the caller telephone 4 and the receiver telephone 5.
　ステップＳ１４において、撃退操作受付部２３は、受信者による撃退操作入力を受け付ける。受信者と発信者との通話が開始された後、受信者は、この通話は特殊詐欺などの迷惑電話であると気づく場合がある。このような場合は、受信者は、撃退操作を入力する。例えば、専用の操作スイッチを押すことにより撃退操作を入力することができる。 In step S14, the repulsion operation reception unit 23 receives the repulsion operation input by the receiver. After the call between the receiver and the caller is initiated, the receiver may find that the call is a nuisance call, such as a wire fraud. In such a case, the receiver inputs a repulsion operation. For example, the repulsion operation can be input by pressing the dedicated operation switch.
　ステップＳ１５において、撃退操作受付部２３は、撃退操作が入力されたか否かを判定する。撃退操作が入力された場合には（Ｓ１５；ＹＥＳ）、ステップＳ２０に処理を進め、そうでなければ（Ｓ１５；ＮＯ）、ステップＳ１６に処理を進める。 In step S15, the repulsion operation reception unit 23 determines whether or not the repulsion operation has been input. If the repulsion operation is input (S15; YES), the process proceeds to step S20, and if not (S15; NO), the process proceeds to step S16.
　ステップＳ１６において、呼接続制御部１１は、発信者電話機４と受信者電話機５との間の呼の接続を継続する。即ち、発信者と受信者は継続して通話することができる。 In step S16, the call connection control unit 11 continues the call connection between the caller telephone 4 and the receiver telephone 5. That is, the sender and the receiver can continue to talk.
　ステップＳ２０において、撃退指令出力部２５は、ＴＴＳサーバ３に撃退指令信号を出力する。ＴＴＳサーバ３は、撃退メッセージのテキストデータをＡＰＬサーバ２の音声データ作成部２４に出力する。音声データ作成部２４は、撃退メッセージのテキストデータを音声データに変換し、この音声データをセッション制御サーバ１に出力する。 In step S20, the repulsion command output unit 25 outputs the repulsion command signal to the TTS server 3. The TTS server 3 outputs the text data of the repulsion message to the voice data creation unit 24 of the APL server 2. The voice data creation unit 24 converts the text data of the repulsion message into voice data, and outputs this voice data to the session control server 1.
　ステップＳ２１において、撃退情報出力部１３は、撃退メッセージの音声データを発信者電話機４に送信する。その結果、発信者電話機４にて撃退メッセージの音声が出力され、特殊詐欺などの迷惑電話の発信者に対して警告することができる。 In step S21, the repulsion information output unit 13 transmits the voice data of the repulsion message to the caller telephone 4. As a result, the voice of the repulsion message is output on the caller telephone 4, and it is possible to warn the caller of the nuisance call such as a special fraud.
　ステップＳ２２において、判定部２１は、迷惑電話を発呼した発信元となる発信者電話機４の電話番号を電話番号記録部２２に一時的に保存する。例えば、判定部２１はメモリ（図示省略）を有しており、該メモリに発信者電話機４の電話番号を保存する。 In step S22, the determination unit 21 temporarily stores the telephone number of the caller telephone 4 that is the source of the nuisance call in the telephone number recording unit 22. For example, the determination unit 21 has a memory (not shown), and stores the telephone number of the caller telephone 4 in the memory.
　ステップＳ２３において、判定部２１は、同一の電話番号に対して撃退指令が発せられた回数が既定値（例えば、３回）に達したか否かを判定する。そして、既定値に達した場合には（Ｓ２３；ＹＥＳ）、ステップＳ２４において、判定部２１は撃退指令が発せられた発信者電話機４の電話番号を、電話番号記録部２２に記録する。 In step S23, the determination unit 21 determines whether or not the number of times the repulsion command has been issued to the same telephone number has reached the default value (for example, three times). Then, when the default value is reached (S23; YES), in step S24, the determination unit 21 records the telephone number of the caller telephone 4 to which the repulsion command is issued in the telephone number recording unit 22.
　一方、ステップＳ１２の処理で、発信者電話機４の電話番号が電話番号記録部２２に記録されていると判定された場合には、ステップＳ１７において、呼接続制御部１１は、受信者電話機５に対し、発信者にて発呼された電話が迷惑電話である可能性があることを通知する。即ち、受信者が発信者との通話を開始する前に、この発信者が迷惑電話の発信元である可能性があることを受信者に通知する。 On the other hand, if it is determined in the process of step S12 that the telephone number of the caller telephone 4 is recorded in the telephone number recording unit 22, the call connection control unit 11 in the receiver telephone 5 in step S17. In response, notify that the call made by the caller may be a nuisance call. That is, before the receiver starts a call with the caller, the receiver is notified that the caller may be the source of the nuisance call.
　ステップＳ１８において、撃退操作受付部２３は、受信者電話機５に対して発信者電話機４の発信者と通話するか、或いは撃退するかを受け付ける。即ち、受信者は、発信者電話機４による発呼に対して迷惑電話の可能性があることを承知したうえで、通話、或いは撃退を選択することができる。 In step S18, the repulsion operation reception unit 23 receives the receiver telephone 5 whether to talk to the caller of the caller telephone 4 or to repel. That is, the receiver can choose to make a call or repel the call, knowing that there is a possibility of a nuisance call for the call made by the caller telephone 4.
　受信者が通話を希望する場合には（Ｓ１８；「通話」）、ステップＳ１９において、呼接続制御部１１は、発信者電話機４と受信者電話機５との間の呼を接続する制御を行い、発信者と受信者との通話を開始する。 If the receiver wishes to make a call (S18; "call"), in step S19, the call connection control unit 11 controls to connect a call between the caller telephone 4 and the receiver telephone 5. Start a call between the caller and the receiver.
　一方、受信者が撃退を希望する場合には（Ｓ１８；「撃退」）、前述したステップＳ２０以降の処理を実施する。即ち、発信者電話機４と受信者電話機５の間で呼の接続を行わず、発信者電話機４に対して撃退メッセージの音声を出力する。 On the other hand, if the receiver wishes to repel (S18; "repel"), the processing after step S20 described above is carried out. That is, the call is not connected between the caller telephone 4 and the receiver telephone 5, and the voice of the repulsion message is output to the caller telephone 4.
　こうして、発信者電話機４から受信者電話機５に対して迷惑電話の発呼があった場合であっても、この発信者電話機４との間の通話を拒否し、迷惑電話を撃退することができるのである。 In this way, even if a nuisance call is made from the caller telephone 4 to the receiver telephone 5, the call with the caller telephone 4 can be rejected and the nuisance call can be repelled. It is.
　［第１実施形態の効果］
　第１実施形態の迷惑電話防止システム１０１は、過去に迷惑電話が発呼された電話機の電話番号を記録する電話番号記録部２２と、発信者電話機４による発呼があった際に、発信者電話機４の電話番号が電話番号記録部２２に記録されているか否かを判定する判定部２１と、発信者電話機４の電話番号が電話番号記録部２２に記録されていない場合には、受信者電話機５に呼を接続する呼接続制御部１１と、受信者電話機５による撃退操作の入力を受け付ける撃退操作受付部２３と、受信者電話機５にて撃退操作が入力された際に、発信者電話機４に対して撃退処理を行うＴＴＳサーバ３（撃退処理部）と、を備えている。 [Effect of the first embodiment]
The nuisance call prevention system 101 of the first embodiment is a telephone number recording unit 22 that records the telephone number of a telephone to which an unsolicited telephone has been called in the past, and a caller when a call is made by the caller telephone 4. The determination unit 21 for determining whether or not the telephone number of the telephone 4 is recorded in the telephone number recording unit 22, and the receiver when the telephone number of the caller telephone 4 is not recorded in the telephone number recording unit 22. The call connection control unit 11 that connects a call to the telephone 5, the repulsion operation reception unit 23 that accepts the input of the repulsion operation by the receiver telephone 5, and the caller telephone when the repulsion operation is input by the receiver telephone 5. It is provided with a TTS server 3 (repulsion processing unit) that performs repulsion processing against 4.
　このように第１実施形態に係る迷惑電話防止システム１０１では、発信者電話機４から受信者電話機５に対して迷惑電話が発呼された場合には、この発信者電話機４の電話番号が電話番号記録部２２に記録されているか否かが判定される。 As described above, in the nuisance call prevention system 101 according to the first embodiment, when a nuisance call is made from the caller telephone 4 to the receiver telephone 5, the telephone number of the caller telephone 4 is the telephone number. It is determined whether or not the recording is recorded in the recording unit 22.
　電話番号記録部２２に記録されていない場合には、発信者電話機４と受信者電話機５との間の通話を確立する。その後、受信者より撃退操作が入力された場合には、発信者電話機４に対して撃退メッセージの音声データを出力する。このため、迷惑電話を発呼した発信者に警告し、この発信者を撃退することが可能となる。従って、迷惑電話の発信元となる発信者の電話番号が頻繁に変更された場合であっても、迷惑電話を撃退することが可能となる。 If it is not recorded in the telephone number recording unit 22, a call is established between the caller telephone 4 and the receiver telephone 5. After that, when the repulsion operation is input from the receiver, the voice data of the repulsion message is output to the caller telephone 4. Therefore, it is possible to warn the caller who called the nuisance call and repel this caller. Therefore, even if the telephone number of the caller who is the source of the nuisance call is changed frequently, it is possible to repel the nuisance call.
　また、同一の発信者電話機４に対して既定値（例えば３回）に達する撃退操作が行われた場合には、この発信者電話機４の電話番号が電話番号記録部２２に記録される。このため、この発信者電話機４より再度の発呼があった場合には、この発信者電話機４による通話は迷惑電話である可能性があることを受信者電話機５に通知し、受信者による「通話」、「撃退」の選択を受け付ける。従って、発信者による迷惑電話が受信者に繋がることを回避でき、迷惑電話の発信者に対して確実に警告し、且つ撃退することが可能となる。 Further, when the same caller telephone 4 is repelled to reach the default value (for example, three times), the telephone number of the caller telephone 4 is recorded in the telephone number recording unit 22. Therefore, when the caller telephone 4 makes another call, the receiver telephone 5 is notified that the call made by the caller telephone 4 may be a nuisance call, and the receiver "" Accepts the selection of "Call" and "Repel". Therefore, it is possible to prevent the nuisance call by the caller from connecting to the receiver, and it is possible to surely warn and repel the caller of the nuisance call.
　更に、迷惑電話の可能性がある場合に、発信者による会話を自動的に録音する機能を備えれば、迷惑電話の解析に役立たせることができる。 Furthermore, if there is a possibility of a nuisance call, if it has a function to automatically record the conversation by the caller, it can be useful for the analysis of the nuisance call.
　また、迷惑電話の発信元となる発信者電話機４の電話番号が、電話番号記録部２２に記録されている場合には、迷惑電話の受信者は、迷惑電話の発信者と直接通話することなく撃退処理を行うことができる。従って、迷惑電話の撃退に不慣れな受信者であっても、容易に迷惑電話を撃退することが可能となる。 Further, when the telephone number of the caller telephone 4 that is the source of the nuisance call is recorded in the telephone number recording unit 22, the receiver of the nuisance call does not directly talk to the caller of the nuisance call. Repulsion processing can be performed. Therefore, even a receiver who is unfamiliar with repelling nuisance calls can easily repel nuisance calls.
　更に、ＴＴＳサーバ３において、迷惑電話を撃退するための撃退メッセージを複数準備しておき、出力する撃退メッセージを適宜選択することも可能である。例えば、図２に示したステップＳ１５の処理で「ＹＥＳ」とされた際に出力する撃退メッセージと、ステップＳ１８の処理で「撃退」とされた際に出力する撃退メッセージを異なるように設定することも可能である。こうすることにより、通話の状況に応じた適切な撃退メッセージを迷惑電話の発信者に出力することが可能となる。 Furthermore, it is also possible to prepare a plurality of repulsion messages for repelling nuisance calls on the TTS server 3 and appropriately select the repulsion messages to be output. For example, the repulsion message output when "YES" is set in the process of step S15 shown in FIG. 2 and the repulsion message output when "repel" is set in the process of step S18 are set differently. Is also possible. By doing so, it is possible to output an appropriate repulsion message according to the call situation to the caller of the nuisance call.
　また、本実施形態では、電話網６に接続された電話機側に特別な機能を必要とせずに、迷惑電話を撃退することが可能となる。 Further, in the present embodiment, it is possible to repel nuisance calls without requiring a special function on the telephone side connected to the telephone network 6.
　なお、上述した実施形態では、迷惑電話防止システム１０１が、セッション制御サーバ１、ＡＰＬサーバ２、及びＴＴＳサーバ３により構成される例について説明したが、本発明はこれに限定されるものではなく、セッション制御サーバ１、ＡＰＬサーバ２、及びＴＴＳサーバ３が同一のサーバに設置される構成とすることも可能である。 In the above-described embodiment, an example in which the junk call prevention system 101 is composed of the session control server 1, the APL server 2, and the TTS server 3 has been described, but the present invention is not limited thereto. It is also possible to configure the session control server 1, the APL server 2, and the TTS server 3 to be installed on the same server.
　また、本実施形態では、撃退操作入力の既定値として３回を例に挙げて説明したが、本発明はこれに限定されるものではなく、１回、２回、或いは４回以上とすることも可能である。 Further, in the present embodiment, the default value of the repulsion operation input has been described by taking three times as an example, but the present invention is not limited to this, and the default value is once, twice, or four times or more. Is also possible.
　［第２実施形態の構成］
　次に、本発明の第２実施形態について説明する。図３は、第２実施形態に係る迷惑電話防止システムの構成を示すブロック図である。 [Structure of the second embodiment]
Next, a second embodiment of the present invention will be described. FIG. 3 is a block diagram showing a configuration of the nuisance call prevention system according to the second embodiment.
　図３に示すように、第２実施形態に係る迷惑電話防止システム１０２は、前述した第１実施形態と同様に、電話網６を介して複数の電話機に接続されている。図３では、迷惑電話の発信元である発信者電話機４と、迷惑電話の発信先である受信者電話機５の２つの電話機を示している。 As shown in FIG. 3, the nuisance call prevention system 102 according to the second embodiment is connected to a plurality of telephones via the telephone network 6 as in the first embodiment described above. FIG. 3 shows two telephones, a caller telephone 4 which is a source of a nuisance call and a receiver telephone 5 which is a destination of a nuisance call.
　迷惑電話防止システム１０２は、セッション制御サーバ１ａと、ＡＰＬサーバ２ａと、オペレータ端末７と、を含む。 The nuisance call prevention system 102 includes a session control server 1a, an APL server 2a, and an operator terminal 7.

For example, when the call made by the caller is a nuisance call or the possibility of a nuisance call is high, the voice data of the repulsion message acquired from the operator terminal 7 is output to the caller telephone 4 of the caller.
　撃退情報出力部１３はまた、判定部２１にて、発信者電話機４による通話が迷惑電話である可能性があると判定された場合には、受信者電話機５に対して、迷惑電話の可能性がある旨の内容を通知する。例えば、発信者電話機４の電話番号が、過去に複数回迷惑電話が発呼された電話番号である場合には、発信者電話機４と受信者電話機５との間で呼を接続する前に、迷惑電話の可能性があることを受信者に知らせる。 If the determination unit 21 determines that the call made by the caller telephone 4 may be a nuisance call, the repulsion information output unit 13 may make a nuisance call to the receiver telephone 5. Notify the content that there is. For example, if the telephone number of the caller telephone 4 is a telephone number for which a nuisance call has been made a plurality of times in the past, before connecting the call between the caller telephone 4 and the receiver telephone 5. Inform the recipient that there is a possibility of a nuisance call.
　撃退指令出力部１５は、受信者電話機５にて撃退操作が入力され、撃退操作受付部１４にて撃退操作の入力が検出された際に、オペレータ端末７に撃退指令信号を出力する。 The repulsion command output unit 15 outputs a repulsion command signal to the operator terminal 7 when the repulsion operation is input by the receiver telephone 5 and the input of the repulsion operation is detected by the repulsion operation reception unit 14.
　ＡＰＬサーバ２ａは、判定部２１と、電話番号記録部２２と、プログラムメモリ２６と、を含む。 The APL server 2a includes a determination unit 21, a telephone number recording unit 22, and a program memory 26.
　電話番号記録部２２は、過去に迷惑電話が発呼された電話機の電話番号を記録する。 The telephone number recording unit 22 records the telephone number of the telephone to which the nuisance call was called in the past.
　判定部２１は、発信者電話機４による発呼があった際に、発信者電話機４の電話番号が電話番号記録部２２に記録されているか否かを判定する。また、発信元となる電話機に対して、撃退操作が所定回数入力された際に、この電話機の電話番号を電話番号記録部２２に記録する。 The determination unit 21 determines whether or not the telephone number of the caller telephone 4 is recorded in the telephone number recording unit 22 when the call is made by the caller telephone 4. Further, when the repulsion operation is input to the telephone as the calling source a predetermined number of times, the telephone number of the telephone is recorded in the telephone number recording unit 22.
