Description

迷惑電話防止装置、迷惑電話防止方法、及び、迷惑電話防止プログラムNuisance Call Prevention Device, Nuisance Call Prevention Method, and Nuisance Call Prevention Program
 本発明は、迷惑電話防止装置、迷惑電話防止方法、及び、迷惑電話防止プログラムに関する。 The present invention relates to a nuisance call prevention device, a nuisance call prevention method, and a nuisance call prevention program.
 迷惑電話を防止する方法として、警察や公共機関からの情報提供やユーザ評価等から、迷惑電話を頻繁に送信する電話番号を迷惑電話のリストとしてデータベースに登録し、このリストに登録されている電話番号からの着信を拒否する方法が知られている。 As a method to prevent nuisance calls, based on information provided by the police and public institutions, user evaluations, etc., telephone numbers that frequently send nuisance calls are registered in the database as a list of nuisance calls. Methods are known for rejecting incoming calls from numbers.
 しかし、上記の方法では迷惑電話自体を減らす効果は低い。即ち、着信時に通話内容が不明なため、ヘッダ情報に基づいて迷惑電話を判断しなければならず、判断材料が不十分でグレーな判定になってしまうことが多い。迷惑電話であるかどうか断定できないグレーな電話については、受信者が着信した後に迷惑電話であるか否かを判断しなければならず、受信者は多くの労力を強いられる。グレーな電話を全て着信拒否することも可能ではあるが、その場合には通常の電話を誤って着信拒否する可能性がある。この問題を解決するために、非特許文献1、2に開示された技術が知られている。 However, the above method is less effective in reducing nuisance calls. In other words, since the content of the call is unknown when the call arrives, it is necessary to determine whether the call is a nuisance call based on the header information. For a gray call that cannot be determined whether it is a nuisance call, the recipient has to judge whether it is a nuisance call after receiving the call, and the recipient is forced to work hard. Although it is possible to reject all gray calls, there is a possibility that regular calls may be rejected by mistake. Techniques disclosed in Non-Patent Documents 1 and 2 are known to solve this problem.
 非特許文献1には、送信者が通話を開始する際に、管理者がこの送信者から預り金を徴収し、この送信者からの通話が迷惑電話であると着信者が判断した場合には、預り金を没収することにより、迷惑電話を防止することが提案されている。また、非特許文献2には、上記預り金を、通信事業者の課金サーバを利用して、通話料金に預り金を含めて徴収する方法が提案されている。 In Non-Patent Document 1, when the sender starts a call, the administrator collects a deposit from the sender, and if the called party determines that the call from this sender is a nuisance call, , proposed to prevent nuisance calls by forfeiting deposits. In addition, Non-Patent Document 2 proposes a method of collecting the above-mentioned deposit by using the billing server of the telecommunications carrier and including the deposit in the call charge.
 しかし、上述した非特許文献1では、送信者から預り金を徴収する必要があるが、迷惑電話撃退サービスを提供する事業者は、送信者に対して契約関係がない場合が多く、この場合には送信者から預り金を徴収することが難しい。 However, in Non-Patent Document 1 mentioned above, it is necessary to collect a deposit from the sender. difficult to collect deposits from senders.
 また、非特許文献2では、電話サービスを提供する全ての事業者で課金システムを改修する必要があり、多くのコストが発生する。更に、着信側の事業者が独自に設定した制裁金を、着信側の利用者からの親告に従って発信側の事業者に請求するため、着信側の事業者に悪意があった場合にこれを規制することが難しい。 Also, in Non-Patent Document 2, it is necessary for all operators who provide telephone services to modify their billing systems, which incurs a lot of costs. In addition, since the fine set independently by the called party is billed to the called party according to the notice from the called party's user, if the called party has malicious intentions difficult to regulate.
 本発明は、上記事情に鑑みてなされたものであり、その目的とするところは、迷惑電話を抑制することが可能な迷惑電話防止装置、迷惑電話防止方法、及び、迷惑電話防止プログラムを提供することにある。 SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its object is to provide a nuisance call prevention device, a nuisance call prevention method, and a nuisance call prevention program capable of suppressing nuisance calls. That's what it is.

 以下、本発明の実施形態について図面を参照して説明する。図1は、第1実施形態に係る迷惑電話防止装置及びその周辺機器の構成を示すブロック図である。
[Configuration of the first embodiment]
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the nuisance call blocking device and its peripherals according to the first embodiment.
 図1に示すように、第1実施形態に係る迷惑電話防止装置100は、通信制御装置1と、ヘッダ評価部2と、課金部3と、を備えている。迷惑電話防止装置100は、電話回線、ネットワークなどを介して、送信者端末4、及び着信者端末5に接続されている。図1では、煩雑さを避けるため、一つの送信者端末4及び一つの着信者端末5のみを示している。 As shown in FIG. 1, the nuisance call prevention device 100 according to the first embodiment includes a communication control device 1, a header evaluation section 2, and a billing section 3. The nuisance call prevention device 100 is connected to the sender terminal 4 and the receiver terminal 5 via telephone lines, networks, and the like. In FIG. 1, only one sender terminal 4 and one receiver terminal 5 are shown to avoid complication.
 ヘッダ評価部2は、送信者端末4から電話がかけられた際に、この送信者端末4からの通話が詐欺やいたずらなどを目的とした迷惑電話であるか否かを評価する。具体的に、ヘッダ評価部2は、送信者端末4がかけた電話の信頼性を評価するため、電話の信頼性を数値化した安全度を算出する。例えば、送信者端末4がかけた電話が明らかに迷惑電話であると評価される場合には安全度を「0」とし、明らかに迷惑電話でないと評価される場合には安全度を「100」とする。ヘッダ評価部2は、「0~100」の範囲で送信者端末4の安全度を評価する。 When a call is made from the sender terminal 4, the header evaluation unit 2 evaluates whether the call from the sender terminal 4 is a nuisance call intended for fraud or mischief. Specifically, in order to evaluate the reliability of the call made by the sender's terminal 4, the header evaluation unit 2 calculates a safety level that quantifies the reliability of the call. For example, if the call made by the sender terminal 4 is clearly evaluated as a nuisance call, the security level is set to "0", and if it is clearly evaluated as not a nuisance call, the security level is set to "100". and The header evaluation unit 2 evaluates the security level of the sender terminal 4 within the range of "0 to 100".
 送信者端末4の安全度を評価する方法の一例として、警察から提供される情報やユーザからのフィードバック情報に基づいて、過去に多くの迷惑電話をかけた電話番号を迷惑電話のリストとして登録する方法を採用することができる。ヘッダ評価部2は、送信者端末4の電話番号がこのリストに登録されている場合には、この送信者端末4からかけられた電話の安全度は「0」であると評価する。 As an example of a method of evaluating the degree of safety of the sender terminal 4, phone numbers that have made many nuisance calls in the past are registered in a list of nuisance calls based on information provided by the police and feedback information from users. method can be adopted. If the telephone number of the sender terminal 4 is registered in this list, the header evaluation unit 2 evaluates that the security level of the call from this sender terminal 4 is "0".
 また、他の例として、親族、友人、及び知人などの信頼できる電話番号を安全な電話のリストとして登録し、送信者端末4の電話番号がこのリストに登録されている場合には、この送信者端末4からかけられた電話は安全度が「100」であると評価する方法を採用することができる。 As another example, if reliable telephone numbers of relatives, friends, acquaintances, etc. are registered as a safe telephone list, and the telephone number of the sender terminal 4 is registered in this list, this transmission A method can be adopted in which a call made from the user's terminal 4 is evaluated to have a security degree of "100."
 更に他の例として、例えば送信者端末4が短時間で頻繁に電話をかけたり、電話番号の下一桁を1ずつ順繰りに変更して電話をかけるなど、送信者端末4による電話のかけ方が迷惑電話のトラヒックパターンと一致する場合に、この送信者端末4の安全度は「0」であると評価する方法を採用することができる。 Still another example is how the sender terminal 4 makes phone calls, for example, the sender terminal 4 makes frequent calls in a short period of time, or calls are made by changing the last digit of the phone number one by one. A method of evaluating the security level of the sender terminal 4 as "0" can be adopted when the number matches the traffic pattern of nuisance calls.
 ヘッダ評価部2はまた、送信者端末4に対して、例えば一人のユーザから迷惑電話との親告があった場合にはこの送信者端末4がかけた電話の安全度を「80」に設定し、複数のユーザから迷惑電話との親告があった場合にはこの送信者端末4がかけた電話の安全度を「20」に設定する。ヘッダ評価部2はまた、安全度に閾値を設定する。ヘッダ評価部2は、閾値を例えば「60」に設定する。ヘッダ評価部2は、上述のように設定した安全度の情報を、通信制御装置1に送信する。 The header evaluation unit 2 also sets the security level of the call made by the sender terminal 4 to "80" when, for example, one user reports a nuisance call to the sender terminal 4. However, if a plurality of users report nuisance calls, the security level of calls made by this sender terminal 4 is set to "20". The header evaluator 2 also sets a threshold for security. The header evaluation unit 2 sets the threshold to, for example, "60". The header evaluation unit 2 transmits the security level information set as described above to the communication control device 1 .
 課金部3は、通信制御装置1において迷惑電話であると評価された送信者端末4に対して、制裁金を課金する処理を実施する。課金部3はまた、送信者端末4から制裁金が支払われた際に、この制裁金を徴収する処理を実施する。課金部3は、後述するブラックリストの登録情報と、QRコード(登録商標)を用いたマイクロペイメントなどの既存の支払いシステムと、を組み合わせることにより、送信者端末4にて支払われた制裁金を徴収する。 The charging unit 3 carries out a process of charging a fine to the sender terminal 4 that has been evaluated as a nuisance call by the communication control device 1 . When the fine is paid from the sender terminal 4, the billing unit 3 also performs a process of collecting the fine. The billing unit 3 collects the fine paid at the sender terminal 4 by combining registration information of the blacklist, which will be described later, and an existing payment system such as micropayment using QR code (registered trademark). Collect.
 例えば、課金部3は、送信者端末4に対して、SMSや音声ガイダンスで制裁金の支払いサイトのアドレスやパスワードを提示する。送信者端末4のユーザは、このサイトにアクセスし、ブラックリストに登録された電話番号とパスワードを入力することにより、制裁金の支払いに必要な情報(QRコード等)を入手し制裁金を支払うことができる。 For example, the billing unit 3 presents the sender terminal 4 with the address and password of the fine payment site by SMS or voice guidance. The user of the sender terminal 4 accesses this site and enters the blacklisted phone number and password to obtain the information (QR code, etc.) necessary to pay the fine and pay the fine. be able to.
 通信制御装置1は、通信制御部11と、評価要求部12と、登録制御部13と、データベース14と、を備える。 The communication control device 1 includes a communication control unit 11, an evaluation request unit 12, a registration control unit 13, and a database 14.
 通信制御部11は、送信者端末4より電話がかけられた場合に、送信者端末4と着信者端末5との間の通話を確立するか否かを制御する。 The communication control unit 11 controls whether or not to establish a call between the sender terminal 4 and the receiver terminal 5 when the sender terminal 4 calls.
 通信制御部11は、ヘッダ評価部2において安全度が「0」と評価された送信者端末4は、着信者端末5との通話を確立しない。 The communication control unit 11 does not establish a call with the callee terminal 5 for the sender terminal 4 whose safety level is evaluated as "0" by the header evaluation unit 2 .
 通信制御部11はまた、送信者端末4の安全度が「0」ではない場合で、送信者端末4の電話番号がブラックリストとして後述するデータベース14に登録され、且つ、この送信者端末4から制裁金が支払われていない場合には、この送信者端末4と着信者端末5との間の通話を確立しない。 The communication control unit 11 also registers the telephone number of the sender terminal 4 as a blacklist in the database 14, which will be described later, in a case where the security level of the sender terminal 4 is not "0". If the fine is not paid, the call between the sender terminal 4 and the receiver terminal 5 is not established.
 通信制御部11はまた、送信者端末4の電話番号がブラックリストに登録されていない場合には、上述したヘッダ評価部2より出力される安全度の数値に応じて、送信者端末4と着信者端末5との間の通話を確立するか否かを判定する。具体的に、通信制御部11は、ヘッダ評価部2より出力された安全度が閾値未満であるか、或いは閾値以上であるかを判定する。「安全度」とは、前述したように「0~100」の数値であり、閾値は例えば「60」に設定される。 If the telephone number of the sender terminal 4 is not registered in the blacklist, the communication control unit 11 also controls the sender terminal 4 and the incoming call according to the numerical value of the degree of safety output from the header evaluation unit 2 described above. determines whether or not to establish a call with the user's terminal 5. Specifically, the communication control unit 11 determines whether the degree of safety output from the header evaluation unit 2 is less than the threshold or greater than or equal to the threshold. The "safety level" is a numerical value of "0 to 100" as described above, and the threshold value is set to "60", for example.
 通信制御部11はまた、送信者端末4の安全度が閾値として設定された「60」以上である場合に、送信者端末4と着信者端末5の間の通話を確立する。通信制御部11はまた、送信者端末4の安全度が「60」未満である場合に、この送信者端末4に対して予め警告通知を行う。「警告通知」とは、例えば「貴方の通話内容が迷惑電話であると判断された場合には、制裁金が課せられます。」などのガイダンスである。 The communication control unit 11 also establishes a call between the sender terminal 4 and the receiver terminal 5 when the security level of the sender terminal 4 is equal to or higher than "60" set as the threshold. The communication control unit 11 also issues a warning notification to the sender terminal 4 in advance when the security degree of the sender terminal 4 is less than "60". A "warning notice" is, for example, guidance such as "If the content of your call is determined to be a nuisance call, a fine will be imposed."
 評価要求部12は、送信者端末4と着信者端末5との間の通話が行われ、その後通話が終了した際に、着信者端末5に対して送信者端末4との通話が迷惑電話であったか否かの評価を要求する。評価要求部12はまた、着信者端末5から送信される評価結果を取得する。 After the call between the sender terminal 4 and the called party terminal 5 is completed, the evaluation request unit 12 informs the called party terminal 5 that the call with the sender terminal 4 is a nuisance call. request an evaluation of whether or not there was. The evaluation requesting unit 12 also acquires the evaluation result transmitted from the called party terminal 5 .
 登録制御部13は、迷惑電話と判定された送信者端末4の電話番号及びこの送信者端末4に関する情報を、ブラックリストとしてデータベース14に登録する。登録制御部13はまた、ブラックリストとしてデータベース14に登録されている送信者端末4が制裁金を支払ったことが課金部3より通知された際に、この送信者端末4をデータベース14から削除する。なお、ブラックリストの情報は、プライバシー保護のため、一般のユーザには開示されない。 The registration control unit 13 registers the phone number of the sender terminal 4 determined to be a nuisance call and information about this sender terminal 4 in the database 14 as a blacklist. The registration control unit 13 also deletes the sender terminal 4 from the database 14 when notified by the billing unit 3 that the sender terminal 4 registered in the database 14 as a blacklist has paid the fine. . Information on the blacklist is not disclosed to general users for privacy protection.
 データベース14は、登録制御部13で迷惑電話と判定された送信者端末4の電話番号及びこの送信者端末4に関連する情報を、ブラックリストとして記憶保存する。 The database 14 stores and stores, as a blacklist, the telephone number of the sender terminal 4 determined to be a nuisance call by the registration control unit 13 and information related to this sender terminal 4.
 [第1実施形態の動作]
 次に、図2、図3を参照して、本実施形態に係る迷惑電話防止装置100の動作を説明する。図2は、通話開始時の処理手順を示すフローチャート、図3は、通話終了時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 nuisance call blocking device 100 according to this embodiment will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 is a flow chart showing a processing procedure at the start of a call, and FIG. 3 is a flow chart showing a processing procedure at the end of a call.
 初めに、図2に示すフローチャートを参照して通話開始時の処理手順について説明する。 First, the processing procedure at the start of a call will be described with reference to the flowchart shown in FIG.
 ステップS11において、送信者端末4より電話がかけられると、ステップS12においてヘッダ評価部2は、送信者端末4の電話番号を解析し上述した方法を採用して、この送信者端末4からの通話が詐欺やいたずらなどを目的とした迷惑電話であるか否かを判定する。 In step S11, when a call is made from the sender terminal 4, in step S12, the header evaluation unit 2 analyzes the telephone number of the sender terminal 4, adopts the above-described method, and performs the call from the sender terminal 4. is a nuisance call intended for fraud or mischief.
 ステップS13において、通信制御部11は、送信者端末4からの通話が明らかな迷惑電話であると判定した場合、即ち、上述した安全度が「0」であると評価された場合には(S13;YES)、ステップS20において、通話を終了する。即ち、送信者端末4にてかけられた電話が明らかな迷惑電話である場合には、着信者端末5との間の通話を確立せず、通話を終了する。 In step S13, when the communication control unit 11 determines that the call from the sender terminal 4 is clearly a nuisance call, that is, when the safety level is evaluated as "0" (S13 ; YES), the call is terminated in step S20. That is, when the call made by the sender terminal 4 is clearly a nuisance call, the call is terminated without establishing a call with the receiver terminal 5. - 特許庁
 一方、送信者端末4にてかけられた電話が明らかな迷惑電話ではないと判定された場合には(S13;NO)、ステップS14において、通信制御部11は、電話をかけた送信者端末4がブラックリストとしてデータベース14に登録されているか否かを判定する。登録されていれば(S14;YES)、ステップS15に処理を進め、そうでなければ(S14;NO)、ステップS17に処理を進める。 On the other hand, if it is determined that the call made by the sender terminal 4 is not clearly a nuisance call (S13; NO), in step S14, the communication control unit 11 controls the sender terminal 4 that made the call. is registered in the database 14 as a blacklist. If it is registered (S14; YES), the process proceeds to step S15; otherwise (S14; NO), the process proceeds to step S17.
 ステップS15において、通信制御部11は、送信者端末4に対し、着信者端末5との間で通話を確立するためには制裁金の支払いが必要である旨のガイダンスを通知する。送信者端末4のユーザは、QRコードを用いたマイクロペイメントなどの支払いシステムにより、課金部3に対して制裁金を支払うことができる。その後、ステップS20において、通信制御部11は、通話を終了する。 In step S15, the communication control unit 11 notifies the sender terminal 4 of guidance to the effect that a fine must be paid in order to establish a call with the receiver terminal 5. The user of the sender terminal 4 can pay the fine to the billing unit 3 by a payment system such as micropayment using a QR code. After that, in step S20, the communication control unit 11 ends the call.
 一方、ステップS14において、送信者端末4の電話番号がブラックリストとしてデータベース14に登録されていないと判定された場合は、ステップS16において、通信制御部11は、この送信者端末4の安全度が予め設定されている閾値以上であるか否かを判定する。一例として、前述したように送信者端末4の安全度を「0」~「100」の数値で評価し、閾値を「60」に設定する。 On the other hand, if it is determined in step S14 that the telephone number of the sender terminal 4 is not registered in the database 14 as a blacklist, in step S16 the communication control section 11 determines that the security level of the sender terminal 4 is It is determined whether or not it is equal to or greater than a preset threshold. As an example, as described above, the security level of the sender terminal 4 is evaluated using numerical values from "0" to "100", and the threshold is set to "60".
 安全度が閾値未満である場合には(S16;NO)、ステップS17に処理を進め、そうでなければ(S16;YES)、ステップS18に処理を進める。 If the degree of safety is less than the threshold (S16; NO), proceed to step S17; otherwise (S16; YES), proceed to step S18.
 ステップS17において、課金部3は、送信者端末4に対して、「貴方の通話内容が迷惑電話であると判断された場合には、ブラックリストに登録され、解除のためには指定した金額の制裁金が課せられます。」などのガイダンスを通知する。ガイダンスを通知した後、送信者端末4がこの通知内容を承諾して通話を継続した場合には、ステップS18に処理を進める。 In step S17, the billing unit 3 tells the sender terminal 4, "If the content of your call is determined to be a nuisance call, you will be registered in the blacklist, and a specified amount of money will be charged to cancel the call." A fine will be imposed.” After notifying the guidance, if the sender terminal 4 accepts the content of this notification and continues the call, the process proceeds to step S18.
 ステップS18において、通信制御部11は、送信者端末4と着信者端末5との間の通話を確立する。 In step S18, the communication control unit 11 establishes a call between the sender terminal 4 and the receiver terminal 5.
 ステップS19において、通信制御部11は、送信者端末4と着信者端末5との間の通話を開始する。 In step S19, the communication control unit 11 starts a call between the sender terminal 4 and the receiver terminal 5.
 こうして、送信者端末4のユーザと、着信者端末5のユーザとの間での通話が行われることになる。 Thus, a call is made between the user of the sender's terminal 4 and the user of the receiver's terminal 5.
 次に、図3に示すフローチャートを参照して通話終了時の処理手順について説明する。 Next, the processing procedure at the end of the call will be described with reference to the flowchart shown in FIG.
 初めに、図3のステップS30において、通信制御部11は、送信者端末4と着信者端末5との間の通話が終了したか否かを判定する。 First, in step S30 of FIG. 3, the communication control unit 11 determines whether or not the call between the sender terminal 4 and the receiver terminal 5 has ended.
 通話が終了した場合には(S30;YES)、ステップS31において、通知制御部11は、この送信者端末4に対して制裁金発生のガイダンスを通知したか否かを判定する。具体的には、通話時において図2に示したS18の処理を実行したか否かを判定する。ガイダンスを通知していなければ(S31;NO)、本処理を終了する。 If the call has ended (S30; YES), in step S31, the notification control unit 11 determines whether or not the sender terminal 4 has been notified of the fine payment guidance. Specifically, it is determined whether or not the process of S18 shown in FIG. 2 has been executed during the call. If guidance has not been notified (S31; NO), this process is terminated.
 ガイダンスを通知した場合には(S31;YES)、ステップS32において、評価要求部12は、着信者端末5に対して送信者端末4との通話についての評価を要求する。具体的に、評価要求部12は、送信者端末4との通話が詐欺やいたずらなどを目的とした迷惑電話であったか否かの評価を要求する。この要求により、着信者端末5のユーザは、迷惑電話であったか否かの評価を入力する。 If the guidance has been notified (S31; YES), the evaluation request unit 12 requests the callee terminal 5 to evaluate the call with the sender terminal 4 in step S32. Specifically, the evaluation requesting unit 12 requests evaluation as to whether or not the call with the sender terminal 4 was a nuisance call intended for fraud or mischief. In response to this request, the user of the callee terminal 5 inputs an evaluation as to whether or not the call was a nuisance call.
 ステップS33において、評価要求部12は、着信者端末5から送信された評価結果に基づいて送信者端末4からの通話が迷惑電話であったか否かの情報を取得する。 In step S33, the evaluation requesting unit 12 acquires information as to whether or not the call from the sender terminal 4 was a nuisance call based on the evaluation result sent from the receiver terminal 5.
 ステップS34において、評価要求部12が上記の通話が迷惑電話でないと判定した場合には(S34;NO)、本処理を終了する。 In step S34, if the evaluation requesting unit 12 determines that the call is not a nuisance call (S34; NO), this process is terminated.
 評価要求部12が上記の通話が迷惑電話であると判定した場合には(S34;YES)、ステップS35において、登録制御部13は、送信者端末4をブラックリストとしてデータベース14に登録する。 If the evaluation request unit 12 determines that the call is a nuisance call (S34; YES), the registration control unit 13 registers the sender terminal 4 as a blacklist in the database 14 in step S35.
 こうして、迷惑電話であると判定された送信者端末をブラックリストとしてデータベース14に登録することができる。また、通話の終了後において登録制御部13は、送信者端末4に対してブラックリストに登録されていることを通知する。また課金部3は、送信者端末4に対してブラックリストの登録を解除するためには制裁金の支払いが必要であることを通知する。例えば、「貴方の電話番号は、ブラックリストに登録されており、制裁金を支払わなければ通話することができません。制裁金の支払い方法は〇〇です。」などのガイダンスを通知する。通知のタイミングは、通話が終了した直後、通話が終了してから一定の時間が経過した後、次回の通話時、などのタイミングとすることができる。こうすることにより、迷惑電話を発信した送信者端末4のユーザに対して、制裁金を支払わなければ通話できないことを認識させることができる。 In this way, it is possible to register in the database 14 as a blacklist the sender terminal determined to be a nuisance call. Further, after the call ends, the registration control unit 13 notifies the sender terminal 4 that the sender is registered in the blacklist. In addition, the billing unit 3 notifies the sender terminal 4 that payment of a fine is required in order to cancel registration of the blacklist. For example, a guidance such as "Your phone number is registered in the blacklist and you cannot make calls unless you pay the fine. The payment method for the fine is XX." The timing of the notification may be immediately after the end of the call, after a certain period of time has passed since the end of the call, at the next call, or the like. By doing so, it is possible to make the user of the sender terminal 4 who has made the nuisance call aware that the call cannot be made unless the fine is paid.
 ステップS37において、課金部3は、送信者端末4から制裁金が支払われたか否かを判定する。 In step S37, the billing unit 3 determines whether or not a fine has been paid from the sender terminal 4.
 送信者端末4のユーザにより制裁金が支払われた場合には(S37;YES)、ステップS38において、登録制御部13は、この送信者端末4をブラックリストから削除する。送信者端末4のユーザにより、制裁金が支払われない場合には(S37;NO)、本処理を終了する。 If the fine is paid by the user of the sender terminal 4 (S37; YES), the registration control unit 13 deletes this sender terminal 4 from the blacklist in step S38. If the user of the sender terminal 4 does not pay the fine (S37; NO), this process is terminated.
 [第1実施形態の効果]
 このようにして、第1実施形態に係る迷惑電話防止装置100は、データベースと、送信者端末が電話をかけた際に、送信者端末と着信者端末との通話を確立する通信制御部と、着信者端末にて、送信者端末との通話が迷惑電話であると判定された際に、この送信者端末に制裁金を要求する課金部と、迷惑電話と判定された送信者端末をブラックリストとして前記データベースに登録する登録制御部と、を備え、通信制御部は、迷惑電話をかけたと判定された送信者端末に対し、制裁金が支払われるまで送信者端末との通話を禁止するものである。
[Effect of the first embodiment]
Thus, the nuisance call prevention device 100 according to the first embodiment includes a database, a communication control unit that establishes a call between the sender terminal and the called party terminal when the sender terminal makes a call, When the called party's terminal determines that the call with the sender's terminal is a nuisance call, the billing section demands a fine from the sender's terminal, and the sender's terminal that is determined as a nuisance call is blacklisted. and a registration control unit that registers in the database as a nuisance call. be.
 本実施形態では、ブラックリストとしてデータベース14に登録されている送信者端末4については、制裁金が支払われなければ、着信者端末5との間の通話を禁止する。従って、悪意を持った送信者端末4のユーザから迷惑電話がかけられることを防止することができる。 In this embodiment, the sender's terminal 4 registered in the database 14 as a blacklist is prohibited from talking to the receiver's terminal 5 unless a fine is paid. Therefore, it is possible to prevent a malicious user of the sender terminal 4 from making a nuisance call.
 本実施形態では、ブラックリストに登録されている送信者端末4は、制裁金を支払われなければ着信者端末5に対して電話をかけることができなくなる。その結果、迷惑電話がかけられる件数を減少させることが期待できる。 In this embodiment, the sender terminal 4 registered in the blacklist cannot make a call to the receiver terminal 5 unless a fine is paid. As a result, it can be expected to reduce the number of nuisance calls.
 また、本実施形態では、課金部3によりマイクロペイメントなどのシステムを利用して迷惑電話をかけた送信者端末から制裁金を徴収するようにしたので、予め契約関係にない迷惑電話の発信者に対して制裁金の支払わせやすくなる。 In addition, in this embodiment, the charging unit 3 uses a system such as micropayment to collect fines from the sender terminal of the nuisance call. It will be easier to pay fines.
 また、制裁金を支払わないユーザは、本サービスの利用者全員に対して通話することができなくなるので、迷惑電話をかけたユーザに対して、自ら制裁金を支払おうとする意識を持たせることが可能となる。その結果、迷惑電話を抑制することが可能となる。 In addition, users who do not pay the fine will not be able to make calls to all users of this service. It becomes possible. As a result, it is possible to suppress nuisance calls.
 また、本実施形態では従来のデポジット方式のように、迷惑電話をかけたか否かに関係なく全てのユーザに導入する必要がないという利点がある。また、迷惑電話をかけたユーザから制裁金を課金するために、全てのユーザとの間で電話事業者を介した契約関係を結ぶ必要がないという利点がある。 In addition, unlike the conventional deposit method, this embodiment has the advantage that it is not necessary to introduce it to all users regardless of whether or not they have made nuisance calls. In addition, there is an advantage that it is not necessary to enter into a contractual relationship with all users via a telephone service provider in order to collect fines from users who have made nuisance calls.
 [第2実施形態の構成]
 次に、第2実施形態について説明する。図4は、第2実施形態に係る迷惑電話防止装置の構成を示すブロック図である。図4に示すように、第2実施形態に係る迷惑電話防止装置100aは、前述した第1実施形態と対比して、通信制御装置1が通話内容評価部15を備えている点で相違する。それ以外の構成は、図1に示した迷惑電話防止装置100と同一であるので、同一符号を付して構成説明を省略する。
[Configuration of Second Embodiment]
Next, a second embodiment will be described. FIG. 4 is a block diagram showing the configuration of a nuisance call blocking device according to the second embodiment. As shown in FIG. 4, the nuisance call blocking device 100a according to the second embodiment differs from the first embodiment described above in that the communication control device 1 includes a call content evaluation unit 15. FIG. Other configurations are the same as those of the nuisance call prevention device 100 shown in FIG.
 通話内容評価部15は、送信者端末4と着信者端末5との通話が確立され、送信者と着信者との間で通話が交わされたときに、音声認識技術などの技術を用いて、この通話内容が迷惑電話であるか否かを判断する。 When a call is established between the sender terminal 4 and the called party terminal 5 and the call is exchanged between the sender and the called party, the call content evaluation unit 15 uses technology such as voice recognition technology to It is determined whether or not the content of the call is a nuisance call.
 一例として、通話内容評価部15は、送信者端末4のユーザと着信者端末5のユーザとの間で交わされた通話の音声データを声紋分析し、過去に迷惑電話をかけたことがあるユーザであるか否かを判定する。通話内容評価部15は、過去に迷惑電話をかけたことがあるユーザであると判定した場合には、この通話は迷惑電話であると判定する。 As an example, the call content evaluation unit 15 analyzes voiceprint analysis of voice data of a call exchanged between the user of the sender terminal 4 and the user of the receiver terminal 5, and determines whether the user who has made a nuisance call in the past is It is determined whether or not. When the call content evaluation unit 15 determines that the user has made a nuisance call in the past, the call is determined to be a nuisance call.
 他の例として、通話内容評価部15は、ロボコール特有の音響パターンから詐欺電話を評価する音響パターン分析、または、音声認識技術を用いて送信者の通話をテキストデータに変換し、このテキストデータの内容を分析して迷惑電話を評価する。 As another example, the call content evaluation unit 15 converts the sender's call into text data using sound pattern analysis for evaluating fraudulent calls from sound patterns specific to Robocall, or speech recognition technology, and converts this text data into text data. Analyze content to evaluate spam calls.
 [第2実施形態の動作]
 次に、第2実施形態に係る迷惑電話防止装置100aの動作について説明する。通話開始時の処理手順は、前述した図2と同様であるので、説明を省略する。
[Operation of Second Embodiment]
Next, the operation of the nuisance call blocking device 100a according to the second embodiment will be described. The processing procedure at the start of a call is the same as in FIG. 2 described above, so a description thereof will be omitted.
 図5は、第2実施形態における通話終了時の処理手順を示すフローチャートである。図5に示すステップS50~S54、ステップS55に示す処理は、図3に示したステップS30~S34、ステップS35に示した処理と同様であるので詳細な説明を省略する。第2実施形態では、ステップS54aの処理を追加している点で、前述した第1実施形態と相違する。 FIG. 5 is a flow chart showing a processing procedure when a call ends in the second embodiment. Since the processes shown in steps S50 to S54 and step S55 shown in FIG. 5 are the same as the processes shown in steps S30 to S34 and step S35 shown in FIG. 3, detailed description thereof will be omitted. The second embodiment differs from the above-described first embodiment in that the process of step S54a is added.
 図5に示すステップS54において、評価要求部12により、通話が迷惑電話であったか否かが判定され、迷惑電話であると判定された場合には(S54;YES)、ステップS54aにおいて、通話内容評価部15は、この通話内容に基づき音声認識処理を用いて、通話内容が迷惑電話である可能性を評価する。 In step S54 shown in FIG. 5, the evaluation request unit 12 determines whether or not the call was a nuisance call, and if it is determined to be a nuisance call (S54; YES), the content of the call is evaluated in step S54a. The unit 15 evaluates the possibility that the content of the call is a nuisance call using voice recognition processing based on the content of the call.
 通話内容評価部15が、この通話内容は迷惑電話である可能性が高いと判定した場合には(S54a;YES)、ステップS55に処理を進め、そうでなければ(S54a;NO)、本処理を終了する。ステップS55以降の処理は、図3に示したステップS35以降の処理と同様である。 If the call content evaluation unit 15 determines that the call content is highly likely to be a nuisance call (S54a; YES), the process proceeds to step S55; otherwise (S54a; NO), this process exit. The processing after step S55 is the same as the processing after step S35 shown in FIG.
 [第2実施形態の効果]
 このように、第2実施形態に係る迷惑電話防止装置100aでは、着信者端末5において迷惑電話であると判定された場合であっても、通話内容評価部15により迷惑電話の可能性が低いと判定された場合には、この通話を迷惑電話として判定しない。
[Effect of Second Embodiment]
As described above, in the nuisance call prevention device 100a according to the second embodiment, even if the called party terminal 5 determines that the call is a nuisance call, the call content evaluation unit 15 determines that the call is unlikely to be a nuisance call. If determined, this call is not determined as a nuisance call.
 従って、着信者端末5のユーザが、勘違い及び悪意などにより迷惑電話と判定した場合であっても、この通話は迷惑電話として判定されないので、送信者端末4が不本意にブラックリストとして登録されることを回避することができる。 Therefore, even if the user of the called party terminal 5 misunderstands or maliciously determines that the call is a nuisance call, the call is not determined as a nuisance call, so the sender terminal 4 is unwillingly registered as a blacklist. can be avoided.
