関連出願
本出願は、2003年3月12日に出願された米国特許仮出願第60/454877号の利益を主張する。
本発明の局面は、通信ネットワークに関し、移動可能な無線音声およびデータ通信ネットワークに関する。
平均的なビジネスの専門家は、卓上電話で使用可能な広範にわたる機能に慣れ親しんでいる。しかしながら、仕事場から離れているときには、たとえ携帯電話を所持しているとしても、これらの機能を使用することができない。単純な電話転送を使用して、卓上電話にかかった電話を、代わりに携帯電話で受信するように別ルートで送出することができる。しかしながら、この単純な転送機構は、ユーザに対して、卓上で慣れ親しんだ機能を提供するものではない。
本発明のシステムおよび方法は、いくつかの特徴を有し、そのいずれもが、単独でその属性の要因となるものではない。後述の請求項に表された本発明の範囲を限定することなく、そのより顕著な特徴をこれから簡単に説明する。この開設を検討した後、特に「詳細な説明」という表題の節を読んだ後には、本システムおよび方法の特徴が従来の通信システムに対していくつかの利点をいかに提供かを読者は理解するであろう。
典型的な職場環境においては、各ユーザには、高性能の卓上電話が提供されている。これらの電話は、ユーザに対して無数の機能を提供するものであり、例えば、内線番号についての短縮ダイヤルの使用機能、通話を他の内線番号、外線番号、またはボイスメールに転送すること、邪魔をしないでくださいという機能を呼び出すこと、未応答の通話のロールオーバをプログラムすること、ボタン一発でボイスメールを取り出すこと、電話会議を確立することなどがある。これらの機能は、卓上電話からは簡単にアクセスされるが、ユーザが旅行中、ランチで外出、または事務所のドアからほんの数ブロック離れたところにいるというように、卓上電話から離れたところにいる場合には、使用できない。
セルラーフロントエンドモジュール402は、セルラーネットワーク上での送受信のためのセルラー加入者装置またはセルホンの機能を提供する。また、セルラーフロントエンドモジュール402は、加入者装置制御モジュール410から情報を受信して、当該情報をデータ搬送および音声搬送チャンネル上で基地局144に対して送出する。米国ニュージャージー州マリーヒルのルーセントテクノロジー社は、GSM参照設計パッケージを販売しており、このパッケージは、製造業者がルーセント社の第1およびそれ以降のGSM送受話器を開発するのに必要なソフトウェアツール、教育およびサポートのすべてを含むデジタル信号プロセッサ(DSP)技術周辺を基礎としており、このパッケージを使用してセルラーフロントエンドモジュール402を製作することができる。同様に、米国カリフォルニア州サンディエゴのクアルコム社は、CDMA対応のセルラーネットワークについての同様の設計、チップ、および情報を提供しており、これらを使用してセルラーフロントエンドモジュール402を製作することができる。セルラーフロントエンドモジュール402は、データ搬送および音声搬送チャンネルの両方上で基地局144から無線リンク信号を受信し(図2、3、4、および6参照)、それに含まれる情報を抽出して、加入者装置制御モジュール410へ渡す。
