Description

【０００１】
【発明の属する技術分野】
本発明は着信履歴表示方式、着信履歴表示方法、呼び返し呼の課金方式及び呼び返し呼の課金方法に関し、特に発信端末と、この発信端末からの呼に対して未応答のときにこの発信端末の着信履歴情報を表示する着信端末と、を有する着信履歴表示方式、着信履歴表示方法、呼び返し呼の課金方式及び呼び返し呼の課金方法に関する。
【０００２】
【従来の技術】
従来、この種の着信履歴表示方式及び呼び返し呼の課金方式は、例えば、着呼に対する呼返し方式（特開平６−４６１４３号公報）に開示されているように、被呼者不応答あるいは話中時に、発呼者が呼を中断した未応答の場合、着呼情報に含まれる発呼者番号を記憶し、被呼者には着呼があったことを通知し、この記憶した発呼者番号の呼び出し要求があれば順次読み出してこの発呼者番号を表示し、簡単な操作でこの発呼者番号の発呼をして発呼者を呼び返している。そして、一般に、この呼び返しの呼に対して発生する料金は呼び返しを行った端末に対して課金される。
【０００３】
【発明が解決しようとする課題】
上述した従来の着信履歴表示方式及び呼び返し呼の課金方式は、未応答の場合、着呼情報に含まれる発呼者番号を記憶し、被呼者（着信者）には着呼があったことを通知し、呼び出し要求に応じてこの発呼者番号を読み出して表示し、簡単な操作でこの発呼者番号の発呼を行って発呼者（発信者）を呼び返している。そして、この呼び返しの呼に対して発生する料金は呼び返しを行った端末に対して課金される。
【０００４】
このため、着信者は着信履歴（記憶された発呼者番号）に基づいて発信者を呼び返すが、この呼び返しが遅い場合や発信者の用件が緊急の場合には、着信者が呼び返しても発信者は用件が済んでいてこの呼び返しが無駄になるという問題がある。
【０００５】
また、着信履歴が不明な電話番号の場合には、この電話番号が、例えば、悪質なワン切り業者の電話番号である可能性があるので、着信者は呼び返しをしたがらない傾向があり、用件がある着信であるにもかかわらず、着信者はこの着信が用件がある着信か否かわからないので、呼び返しされないという問題がある。
【０００６】
更に、呼び返し時に発生する料金は、用件のある発信者が負担すべきと考えられるが、常に呼び返しを行う着信者が負担する必要があるという問題がある。
【０００７】
本発明の目的はこのような従来の欠点を除去するため、無駄にならない呼び返しができ、用件がある着信か否かがわかり、呼び返しを行う着信者が常に呼び返しの呼に対して発生する料金を負担する必要があるということのない着信履歴表示方式、着信履歴表示方法、呼び返し呼の課金方式及び呼び返し呼の課金方法を提供することにある。

【００１９】
発信端末１は、発信者の指示に従い、着信履歴の有効期限情報（この発信端末１への着信端末２からの呼び返しの希望期限を示す）と発信端末１に対して着信端末２が発呼する呼び返しの呼の課金区分を示す課金区分情報とを指定し第１の発呼要求メッセージを着信端末２に向けて網３に出力し、網３より着信端末２からの呼び出し中メッセージを受け、発信者が着信端末２に対しての呼接続の放棄を希望するときに、この発信者の指示に従い、切断メッセージを着信端末２に向けて網３に出力する。
【００２０】
着信端末２は、網３より第１の発呼要求メッセージを受けこの第１の発呼要求メッセージより着信履歴の有効期限情報と課金区分情報とを抽出して格納し、呼び出し中メッセージを発信端末１に向けて網３に出力し、網３より発信端末１からの切断メッセージを受けて受けた後にこの格納した着信履歴の有効期限情報と課金区分情報とを発信端末１の着信履歴情報とともに表示する。表示した後に、着信者の指示に従い、着信履歴情報で示す発信端末１に向けて第２の発呼要求メッセージを呼び返しの発呼として網３に出力する。
【００２１】
網３は、発信端末１より第１の発呼要求メッセージを受けてこの第１の発呼要求メッセージより着信履歴の有効期限情報と課金区分情報とを抽出して登録し、この第１の発呼要求メッセージを着信端末２に出力し、着信端末２より呼び出し中メッセージを受けて発信端末１に出力し、発信端末１より切断メッセージを受けて着信端末２に出力する。そして、着信端末２より第２の発呼要求メッセージを受けこの第２の発呼要求メッセージを受けたときが、この登録した着信履歴の有効期限情報で示す期限内であるときに、この第２の発呼要求メッセージで示す呼び返しの呼に対して発生する料金を、この登録した課金区分情報に基づいて課金する。
【００２２】
課金区分情報は、呼び返しの呼に対して発生する料金を発信端末１と着信端末２とのうちのいずれか一方を指定して課金することを示す情報である。
【００２３】
次に、本実施の形態の呼び返し呼の課金方式の動作を図２及び図３を参照して詳細に説明する。この呼び返し呼の課金方式の動作は、本発明の着信履歴表示方式の動作を含んでいる。

図３は、着信端末上での表示の一例を示す図であり、着信端末２の表示器に発信端末１の加入者番号を含む着信履歴情報と、着信履歴の有効期限情報と、課金区分情報とを表示した例を示している。
【００２６】
図１において、図２に示すように、ステップ２１では、発信者の指示に従い、発信端末１により、着信端末２の加入者番号（例えば０６−６９４５−ｙｙｙｙ：ｙは数字）と着信履歴の有効期限情報（例えば、２００２年２月１２日ＰＭ３時３０分）と呼び返しの呼の課金区分を示す課金区分情報（例えば、着信課金：この場合は、発信端末１に対して課金する）とを指定し発信端末１の加入者番号（例えば０６−６９４５−ｘｘｘｘ：ｘは数字）と着信端末２の加入者番号と着信履歴の有効期限情報と課金区分情報とを含めた第１の発呼要求メッセージ（ＳＥＴＵＰ）を着信端末２に向けて網３に出力する。この第１の発呼要求メッセージ（ＳＥＴＵＰ）は、例えば、ユーザーネットワークＩ／Ｆ（Ｉ４．５で示すプロトコル）上で送受信するメッセージである。
【００２７】
このとき、着信履歴の有効期限情報と課金区分情報（これらの情報を情報Ａとする。）とは、例えば、発信端末１上のボタン等を操作して発信端末１の表示器上に表示された操作誘導表示に従って、あるいは予め定められた操作によって入力する。
【００２８】
ステップ２２では、網３は、発信端末１より第１の発呼要求メッセージを受けこの第１の発呼要求メッセージに含まれる発信端末１の加入者番号と着信端末２の加入者番号と着信履歴の有効期限情報と課金区分情報とを抽出して登録し、着信端末２の加入者番号の示す着信端末２に第１の発呼要求メッセージを出力する。
【００２９】
ステップ２３では、着信端末２は、網３より第１の発呼要求メッセージを受けこの第１の発呼要求メッセージに含まれる発信端末１の加入者番号と着信履歴の有効期限情報と課金区分情報とを抽出し格納して呼び出し中メッセージ（ＣＡＬＬＰｒｏｃ）を網３に出力する。
【００３０】
ステップ２４では、網３は、着信端末２より呼び出し中メッセージを受けて発信端末１にこの呼び出し中メッセージを出力する。
【００３１】
ステップ２５では、発信端末１は、網３より呼び出し中メッセージを受けて、呼び出し中であること発信者に示し、発信者が、着信端末２に対しての呼接続の放棄を希望するときに、発信者の指示に従い（例えば、発信端末１をオンフックする等により）、切断メッセージ（ＤＩＳＣ）を網３に出力する。
【００３２】
ステップ２６では、網３は、発信端末１より切断メッセージを受けて着信端末２にこの切断メッセージを出力する。
【００３３】
ステップ２７では、着信端末２は、網３より切断メッセージを受けて呼解放要求メッセージ（ＲＥＬ）を網３に出力する。
【００３４】
ステップ２８では、網３は、着信端末２より呼解放要求メッセージを受けて発信端末１にこの呼解放要求メッセージを出力する。
【００３５】
ステップ２９では、発信端末１は、網３より呼解放要求メッセージを受けて、呼解放を了承し呼解放完了メッセージ（ＲＥＬＣＯＭＰ）を網３に出力する。
【００３６】
ステップ３０では、網３は、発信端末１より呼解放完了メッセージを受けて着信端末２にこの呼解放完了メッセージを出力する。
【００３７】
ステップ３１では、着信端末２は、網３より呼解放完了メッセージを受けてステップ２３で格納した着信履歴の有効期限情報と課金区分情報とを発信端末１の加入者番号を含む着信履歴情報とともに図３で示すように表示する。
【００３８】
ステップ３２では、着信端末２は、ステップ３１で表示した着信履歴情報で示す加入者番号の発信端末１に対して、着信者が、呼び返しの呼を希望するときに、着信者の指示に従い（例えば、この発信端末１の加入者番号に発信する等により）、この表示した着信履歴情報内の発信端末１の加入者番号と自着信端末２の加入者番号とを含む第２の発呼要求メッセージ（ＳＥＴＵＰ）を呼び返しの発呼として網３に出力する。
【００３９】
ステップ３３では、網３は、着信端末２より第２の発呼要求メッセージを受信し、この第２の発呼要求メッセージに含まれる発呼元である着信端末２の加入者番号と発呼先である発信端末１の加入者番号とに対応するステップ２２で登録した着信履歴の有効期限情報と課金区分情報とを取り出しこの着信履歴の有効期限情報で示す期限内に第２の発呼要求メッセージを受信したか否かを調べ調べた結果が期限内に第２の発呼要求メッセージを受信したことを示すときに第２の発呼要求メッセージで示す呼び返しの呼に対して発生する料金を課金区分情報に基づいて課金する。この例では、ステップ２１で課金区分情報を着信課金としたので、発信端末１に対して課金する。
【００４０】
【発明の効果】
以上説明したように、本発明によれば、発信端末により、着信履歴の有効期限情報を指定して着信端末に向け発呼し、着信端末により、発信端末が発呼した呼に対して自着信端末が未応答のときにこの着信履歴の有効期限情報を発信端末の着信履歴情報とともに表示するため、
着信者は、着信履歴情報で示す発信者に呼び返しを行うときに、この表示された着信履歴の有効期限情報を見てこの有効期限情報の示す期限が過ぎているときには発信者に対して呼び返しを行わないようにできるので、無駄になる呼び返しをしないですむ。
【００４１】
また、着信端末に、着信履歴情報とともに着信履歴の有効期限情報が表示されるので、着信者は、この着信が用件のある着信であることがわかる。
【００４２】
また、本発明によれば、発信端末により、着信履歴の有効期限情報と課金区分情報（これらを情報Ａとする）とを指定して第１の発呼要求メッセージを網を介して着信端末に出力し、網を介して着信端末より呼び出し中メッセージを受け、着信端末に対しての呼接続の放棄を希望するときに、切断メッセージを網を介して着信端末に出力し、着信端末により、網を介して発信端末より第１の発呼要求メッセージを受けこのメッセージから情報Ａを抽出して格納し、呼び出し中メッセージを網を介して発信端末に出力し、網を介して発信端末より切断メッセージを受けて、この格納した情報Ａを発信端末の着信履歴情報とともに表示し、表示した後に着信履歴情報で示す発信端末に向けて第２の発呼要求メッセージを呼び返しの発呼として網に出力し、網により、着信端末より第２の発呼要求メッセージを受けこのメッセージの受信が着信履歴の有効期限情報で示す期限内のときに、呼び返しの呼に対して発生する料金を課金区分情報に基づいて課金するため、着信端末に、着信履歴情報とともに着信履歴の有効期限情報と課金区分情報とが表示されるので、着信者は、この着信が用件のある着信であることがわかる。
【００４３】
また、網により、着信履歴の有効期限情報で示す期限内の呼び返しの呼に対して発生する料金を課金区分情報に基づいて課金するので、呼び返しを行う着信者が常に呼び返しの呼に対して発生する料金を負担する必要があるということがない。
【００４４】
更に、発信者が課金区分情報を着信課金とすることにより、この発信者の発信端末に、着信者からの呼び返しの呼に対して発生する料金を課金するようになるので、着信履歴の有効期限情報で示す期限内での呼び返しの呼が期待できる。

BACKGROUND OF THE INVENTION
The present invention relates to an incoming call history display method, an incoming call history display method, a call back charging method and a call back charging method, and more particularly to a calling terminal and the calling terminal when a call from the calling terminal is not answered. The present invention relates to an incoming call history display method, an incoming call history display method, a call back charging method and a call back charging method.
[0002]
[Prior art]
Conventionally, this kind of incoming call history display method and call back charging method are, for example, as described in the call back method for an incoming call (Japanese Patent Laid-Open No. 6-46143), and the called party does not answer or talks. In the middle, if the caller has not answered the call, the caller number included in the call information is stored, the callee is notified that the call has been received, and the stored call If there is a call request for the calling party number, the calling party number is sequentially read and displayed, and the calling party number is called by a simple operation to call back the calling party. In general, the charge generated for this call back is charged to the terminal that made the call back.
[0003]
[Problems to be solved by the invention]
The above-described conventional incoming call history display method and call back billing method store the calling party number included in the incoming call information when there is no answer, and the called party (called party) has received the incoming call. This caller number is read and displayed in response to a call request, and the caller number is called by a simple operation to call back the caller (caller). The fee generated for this call back is charged to the terminal that made the call back.
[0004]
For this reason, the called party calls back the caller based on the incoming call history (stored caller number). If this call is late or the caller's request is urgent, the called party calls the caller. There is a problem that even if the call is returned, the caller has finished his business and the call back is wasted.
[0005]
Also, in the case of a phone number whose incoming call history is unknown, this phone number may be, for example, the phone number of a malicious one-off operator, so the callee tends not to call back, There is a problem that the callee is not called back because the callee does not know whether or not the call is a call with a request even though the call has a request.
[0006]
Further, although it is considered that the fee generated at the time of call back should be borne by the caller with the request, there is a problem that it is necessary to pay the callee who always calls back.
[0007]
The object of the present invention is to eliminate such conventional drawbacks, so that it is possible to call back without waste, to know whether there is an incoming call or not, and the called party who calls back always responds to the call back. An object of the present invention is to provide an incoming call history display method, an incoming call history display method, a call back charging method, and a call back charging method that do not need to bear the generated charges.
[0008]
[Means for Solving the Problems]
A first incoming call history display method of the present invention is an incoming call history display method comprising: a calling terminal; and a receiving terminal that displays incoming call history information of the calling terminal when a call from the calling terminal has not been answered. In
The calling terminal for calling the receiving terminal by specifying expiration date information of an incoming history indicating a time limit for calling back the call that the receiving terminal has received and has not answered ;
The receiving terminal that displays the expiration date information of the incoming call history together with the incoming call history information when the call receiving terminal has not answered the call made by the outgoing terminal;
It is configured with.
[0009]
The second incoming call history display method of the present invention displays the incoming call history information of the calling terminal connected to the calling terminal via the network when the call from the calling terminal is not answered. Incoming call history display method having a receiving terminal,
The expiration date information indicating the time limit for calling back the call that has been received by the receiving terminal and has not been answered is designated and the subscriber number of the receiving terminal is designated.

【The invention's effect】
As described above, according to the present invention, the calling terminal designates the expiration date information of the incoming call history and makes a call to the receiving terminal, and the receiving terminal makes an incoming call for the call originated by the calling terminal. In order to display the expiration date information of this incoming call history together with the incoming call history information of the calling terminal when the terminal is unanswered,
When the called party calls back to the caller indicated by the incoming call history information, the caller sees the expiration date information of the displayed incoming call history and when the deadline indicated by the expiration date information has passed, Since it is possible not to perform the return, there is no need to make a unnecessary call back.
[0041]
In addition, since the expiration date information of the incoming call history is displayed together with the incoming call history information on the incoming call terminal, the callee knows that this incoming call is an incoming call with a request.
[0042]
Further, according to the present invention, the calling terminal designates the expiration date information of the incoming call history and the charging classification information (these are referred to as information A) and sends the first call request message to the receiving terminal via the network. When receiving a ringing message from the receiving terminal via the network and wishing to abandon the call connection to the receiving terminal, a disconnect message is output to the receiving terminal via the network. The first call request message is received from the calling terminal via the network, information A is extracted from this message and stored, the calling message is output to the calling terminal via the network, and the disconnect message is sent from the calling terminal via the network. In response, the stored information A is displayed together with the incoming call history information of the calling terminal, and after the display, the second call request message is sent to the network as a call back to the calling terminal indicated by the incoming call history information. When the second call request message is received from the receiving terminal by the network and the reception of this message is within the time limit indicated by the expiration date information of the incoming call history, the charge generated for the call back is charged Since charging is based on the information, the expiration date information of the incoming call history and the billing classification information are displayed together with the incoming call history information on the receiving terminal, so that the caller knows that this incoming call is a call with a request .
[0043]
In addition, since the network charges for the call back within the time limit indicated by the expiry date information of the incoming call history based on the charge classification information, the callee who performs the call always calls back the call. There is no need to pay for the fee.
[0044]
In addition, when the caller sets the charge category information as an incoming call charge, the caller's caller terminal is charged for the charge generated for the call back from the caller. A call back within the time limit indicated by the time limit information can be expected.
