Abstract
【解決手段】電話システム内の交換機のそれぞれにそのIPアドレスを対応付けたデータベースであるノード情報DBに加え、IP端末の内線番号にこのIP端末の規定の接続先の交換機の識別子を対応付けたデータベースである他ノードユーザ情報DBを各交換機に記憶させる。そして接続要求がIP端末から交換機に送信されると、交換機は要求元の内線番号に対応する収容先交換機のIPアドレスを要求元IP端末に通知する。これを受けたIP端末は、このIPアドレスに向けて接続要求を再送信する。
【選択図】 図1
Description
この発明は上記事情によりなされたもので、その目的は、場所を問わずシステムにログインすることの可能な電話システムを低コストで提供することにある。
IP端末200からの特番入力あるいは内線番号の入力により交換機2に接続要求が通知され、ログインシーケンスが開始される。この接続要求を受けた交換機2は、交換機2に属さない内線番号が通知された場合、その内線番号の属する交換機を特定する。ここではノード10に属する内線番号が通知されたので、交換機20はIP端末200に交換機1(ノード10)のIPアドレスを端末接続応答にて通知する。
Claims (4)
- 通信端末からの接続要求を認証処理の結果に応じて許容する複数の交換機と、前記複数の交換機を接続して、異なる交換機に接続される通信端末の相互間に内線通信環境を形成する通信網とを備える電話システムにおいて、
前記複数の交換機は、
前記通信端末の内線番号と当該通信端末の規定の接続先の交換機のアドレス情報とを対応付けた管理データベースと、
前記接続要求を受けた場合に、この接続要求に含まれる要求元通信端末の内線番号をキーとして前記管理データベースを検索して前記要求元通信端末の規定の接続先の交換機のアドレス情報を取得する取得処理部と、
この取得処理部により取得されたアドレス情報を前記要求元通信端末に通知する通知処理部とを備え、
前記通信端末は、
前記交換機から前記アドレス情報を通知された場合に、このアドレス情報宛てに前記接続要求を再送信する再接続要求処理部を備えることを特徴とする電話システム。 - 前記管理データベースは、
前記通信端末の内線番号に当該通信端末の規定の接続先の交換機情報を対応付けた第1データベースと、
前記複数の交換機のそれぞれにそのアドレス情報を対応付けた第2データベースとを備え、
前記取得処理部は、
前記要求元通信端末の内線番号をキーとして前記第1データベースを検索してこの内線番号に対応する交換機情報を取得し、この交換機情報をキーとして前記第2データベースを検索してこの交換機情報に対応するアドレス情報を取得することを特徴とする請求項1に記載の電話システム。 - 前記通信網は、公衆網を経由しない私設網であることを特徴とする請求項1に記載の電話システム。
- 前記私設網は、IP(Internet Protocol)ネットワークであることを特徴とする請求項3に記載の電話システム。
