Description

【０００１】
【発明の属する技術分野】
本発明は発側転送方式および発側転送方法に関し、特に発信者の電話端末を収容する発側の交換機において、着信者の電話端末から他の電話端末への着信転送を、着信者の電話端末の操作によって通話中に行うことを可能とする、発側転送方式および発側転送方法に関する。
【０００２】
【従来の技術】
従来の着信転送の方式について、図５を参照して説明する。
【０００３】
図５は、従来の着信転送の方式を示すブロック図である。
【０００４】
図５に示す方式は、発信者の電話端末であるところの発信側電話端末Ａと、交換機能を有し発信側電話端末Ａを収容する交換機であるところの発側交換機１００と、着信側の電話端末であるところの着信側電話端末Ｂ１と着信側電話端末Ｂ２と、交換機能を有し着信側電話端末Ｂ１を収容する交換機であるところの着側交換機２００と、これらを相互に接続する通信網３００とを備える構成となっている。そして、着側交換機２００は、着信転送を行う機能を有する転送制御装置２０１と、着信転送における転送先の電話番号を記憶するメモリー２０２と、メモリー２０２に記憶されている転送先の電話番号に発信する発信装置２０３とから構成されている。
【０００５】
この構成において、着信側電話端末Ｂ１に着呼が有った場合に、該呼を着信側電話端末Ｂ２に転送するときの動作について図５を再度参照して説明する。
【０００６】
先ず、着信側電話端末Ｂ１への着呼を着信側電話端末Ｂ２へ転送するために、予め着信側電話端末Ｂ１から転送先の着信側電話端末Ｂ２の電話番号を着側交換機２００に登録する（図５のＲ０）。転送先の電話番号は、着側交換機２００のメモリー２０２に登録され記憶される。
【０００７】
発信側電話端末Ａから着信側電話端末Ｂ１に対する発呼があると（図５のＲ１）、該呼は発側交換機１００及び着側交換機２００を介して着信側電話端末Ｂ１に着呼し、着側交換機２００内では初期パスＲ２が形成される。
【０００８】
その後、該呼に対し着信側電話端末Ｂ１が無応答あるいは時間切れとなった時（図５のＲ３）、着側交換機２００の転送制御装置２０１は着信側電話端末Ｂ１を保留し（図５のＲ４）、次に転送制御装置２０１は発信装置２０３を用いて、メモリー２０２に登録されている転送先の電話番号をダイヤルし発信する（図５のＲ５）。そして、転送先である着信側電話端末Ｂ２が応答したら（図５のＲ６）、転送制御装置２０１は発信側電話端末Ａを着信側電話端末Ｂ２に接続する（図５のＲ７）。
【０００９】
以上の動作を行うことにより、着信転送が行われる。
【００１０】
【発明が解決しようとする課題】
上述した従来の着信転送の方式は、予め転送先の電話番号を交換機に登録しておくものであるため、１度の転送先変更しか行うことが出来ず、通話中などに臨機応変に転送先を変更することが出来ない、という欠点を有している。
【００１１】
また、着側交換機において転送処理を行うものであるため、発信者と着信側の転送者との両者に通話料金が課金される、という欠点を有している。
【００１２】
本発明は上述した事情を改善するために成されたものであり、本発明の目的は、発信者の電話端末を収容する発側の交換機において、着信者の電話端末から他の電話端末への着信転送を、着信者の電話端末の操作によって通話中に行うことを可能とする、発側転送方式および発側転送方法を提供することにある。

【発明の実施の形態】
次に、本発明の実施の形態について図面を参照して説明する。
【００２４】
図１は、本発明の発側転送方式の一実施形態を示すブロック図である。
【００２５】
図１に示す本実施の形態は、発信者の電話端末であるところの発信側電話端末Ａと、交換機能を有し発信側電話端末Ａを収容する交換機であるところの発側交換機１と、着信側の電話端末であるところの着信側電話端末Ｂ１と着信側電話端末Ｂ２と、交換機能を有し着信側電話端末Ｂ１を収容する交換機であるところの着側交換機２と、これらを相互に接続する通信網３とを備える構成となっている。そして、発側交換機１は、着信転送を行う機能を有する転送制御装置１１と、着信転送における転送先の電話番号を記憶するメモリー１２と、メモリー１２に記憶されている転送先の電話番号に発信する発信装置１３とから構成されている。なお、本実施形態の電話端末（Ａ、Ｂ１、Ｂ２）は、携帯電話やＰＨＳ端末或いは固定電話端末の何れであっても良い。
【００２６】
図１において、発信側電話端末Ａと着信側電話端末Ｂ１とが通話中であるものとする。発側交換機１の転送制御装置１１は、発信側電話端末Ａからフラッシュ信号を受信すると、発信側電話端末Ａを保留し、着信側電話端末Ｂ１を発側交換機１のメモリー１２に接続する。その後、着信側電話端末Ｂ１から、転送先の着信側電話端末Ｂ２の電話番号とプッシュ信号を受信すると、該電話番号をメモリー１２に登録すると共に、着信側電話端末Ｂ１を保留し、発信装置１３を起動する。発信装置１３は、メモリー１２に記憶されている前記電話番号に発信する。発信装置１３と前記電話番号の着信側電話端末Ｂ２が接続されると、転送制御装置１１は発信側電話端末Ａと着信側電話端末Ｂ２とを接続し、着信側電話端末Ｂ１を切断する。
【００２７】
尚、上述したフラッシュ信号は、例えば、発信側電話端末Ａのフラッシュキーの押下により発側交換機１に送信される信号である。また、プッシュ信号は、例えば、着信側電話端末Ｂ１の「＃」キーの押下により発側交換機１に送信される信号である。
【００２８】
次に図２を参照して、本実施形態の動作について詳細に説明する。
【００２９】
図２は、本実施形態の動作を説明する図である。
【００３０】
なお、図２において図１に示す構成要素に対応するものは同一の参照数字または符号を付し、その説明を省略する。
【００３１】
図２では、発信側電話端末Ａから着信側電話端末Ｂ１に対して発呼し、該呼が発側交換機１、通信網３、着側交換機２を介して接続され、発信側電話端末Ａと着信側電話端末Ｂ１とが通話中であるものとする。すなわち、発側交換機１内には、発信側電話端末Ａと着信側電話端末Ｂ１とを接続する初期パスＳ０が形成されているものとする。
【００３２】
発信側電話端末Ａにおいて、フラッシュキーの押下等によりフラッシュ信号を発側交換機１に送出し、該フラッシュ信号が発側交換機１の転送制御装置１１に与えられると（図２のＳ１）、転送制御装置１１は発信側電話端末Ａを保留し（図２のＳ２）、着信側電話端末Ｂ１を発側交換機１のメモリー１２に接続する（図２のＳ３）。
【００３３】
次に、着信側電話端末Ｂ１から、転送先の着信側電話端末Ｂ２の電話番号を入力して、「＃」キーの押下等によりプッシュ信号を送出し、該電話番号と該プッシュ信号が発側交換機１の転送制御装置１１に与えられると（図２のＳ４、Ｓ５）、転送制御装置１１は該電話番号をメモリー１２に記憶させる。そして、転送制御装置１１は着信側電話端末Ｂ１を保留し（図２のＳ６）、発信装置１３を起動する。
【００３４】
発信装置１３は、メモリー１２を参照して転送先の電話番号（すなわち着信側電話端末Ｂ２）に発信する（図２のＳ７）。
【００３５】
着信側電話端末Ｂ２が応答したら（図２のＳ８）、転送制御装置１１は、発信側電話端末Ａと着信側電話端末Ｂ２を接続し（図２のＳ９）、着信側電話端末Ｂ１を切断する（図２のＳ１０）。
【００３６】
このようにして、発信側電話端末Ａと着信側電話端末Ｂ１との接続を、その通話中に、着信側電話端末Ｂ２へ転送することが可能となる。
【００３７】
次に図３、図４を参照して、本発明の第２の実施形態について説明する。
【００３８】
図３は、本発明の第２の実施形態を示すブロック図である。
【００３９】
図３に示す第２の実施形態は、発側交換機１のメモリーの構成を変更した構成を示すものであり、図１に示した第１の実施形態のメモリー１２及び発信装置１３が、発信装置１４に置き換えられている点でのみ異なっている。従って、図３において図１に示す構成要素に対応するものは同一の参照数字または符号を付し、その説明を省略する。
【００４０】
図３の発側交換機１は以下の機能を備える。
【００４１】
図３においては、発信側電話端末Ａと着信側電話端末Ｂ１とが通話中であるものとする。発側交換機１の転送制御装置１１は、発信側電話端末Ａからフラッシュ信号を受信すると、発信側電話端末Ａを保留し、着信側電話端末Ｂ１を発側交換機１の発信装置１４に接続する。その後、着信側電話端末Ｂ１から、転送先の着信側電話端末Ｂ２の電話番号とプッシュ信号を受信すると、発信装置１４は、該電話番号にそのまま発信する。発信装置１４と前記電話番号の着信側電話端末Ｂ２が接続されると、転送制御装置１１は発信側電話端末Ａと着信側電話端末Ｂ２とを接続し、着信側電話端末Ｂ１を切断する。
【００４２】
次に図４を参照して、図３に示した第２の実施形態の動作について詳細に説明する。
【００４３】
図４は、第２の実施形態の動作を説明する図である。
【００４４】
なお、図４において図３に示す構成要素に対応するものは同一の参照数字または符号を付し、その説明を省略する。
【００４５】
図４では、発信側電話端末Ａから着信側電話端末Ｂ１に対して発呼し、該呼が発側交換機１、通信網３、着側交換機２を介して接続され、発信側電話端末Ａと着信側電話端末Ｂ１とが通話中であるものとする。すなわち、発側交換機１内には、発信側電話端末Ａと着信側電話端末Ｂ１とを接続する初期パスＴ０が形成されているものとする。
【００４６】
発信側電話端末Ａにおいて、フラッシュキーの押下等によりフラッシュ信号を発側交換機１に送出し、該フラッシュ信号が発側交換機１の転送制御装置１１に与えられると（図４のＴ１）、転送制御装置１１は発信側電話端末Ａを保留し（図４のＴ２）、着信側電話端末Ｂ１を発側交換機１の発信装置１４に接続する（図４のＴ３）。
【００４７】
次に、着信側電話端末Ｂ１から、転送先の着信側電話端末Ｂ２の電話番号を入力して、「＃」キーの押下等によりプッシュ信号を送出し、該電話番号と該プッシュ信号が発側交換機１の転送制御装置１１に与えられると（図４のＴ４、Ｔ５）、転送制御装置１１は該電話番号を発信装置１４に渡し、発信装置１４はそのまま該電話番号（すなわち着信側電話端末Ｂ２）に発信する（図４のＴ６）。
【００４８】
着信側電話端末Ｂ２が応答したら（図４のＴ７）、転送制御装置１１は、発信側電話端末Ａと着信側電話端末Ｂ２を接続し（図４のＴ８）、着信側電話端末Ｂ１を切断する（図４のＴ９）。
【００４９】
このようにして、発信側電話端末Ａと着信側電話端末Ｂ１との接続を、その通話中に、着信側電話端末Ｂ２へ転送することが可能となると共に、第２の実施形態においては、着信側電話端末Ｂ１からのプッシュ信号をそのまま伝送しているので、第１の実施形態において必要であったメモリーが不要になる、という効果が得られる。
【００５０】
【発明の効果】
以上説明したように、本発明の発側転送方式および発側転送方法は、発側交換機によって通話の転送を行っているため、通話中にその都度、転送先を選択して何度でも転送が行えるという効果を有している。
【００５１】
また、着信側の電話端末からの電話番号の入力によって転送先を指定しているため、電話番号の聞き間違いによる誤転送を防止できる、という効果を有している。
【００５２】
さらに、発側交換機による転送であるため、発側の交換機に収容されている発側の電話端末にのみ課金され、発側と転送側の両電話端末に２重に課金されることを防止できるという効果を有している。
【００５３】
またさらに、通話中にその都度転送先を選択できるので、通話コスト面や通話品質の優れる電話端末で通話を継続できるという効果を有している。
