前記SIP/SDPベースのネットワークコントローラは、ネットワークリソースについて交渉し、前記ネットワークリソースを割り振り、そして前記ネットワークリソースを再構成するように構築され、前記SIP/SDPベースのネットワークコントローラはSIPバック−ツー−バックユーザエージェントを含み、
前記SIP/SDPベースのネットワークコントローラは、第1ユーザから会議呼要求を受信するよう構成されており、前記会議呼要求はSIP/SDP信号指示により送信され、
前記会議呼要求の受信に応じて、前記SIP/SDPベースのネットワークコントローラは、SIPユーザエージェントを含むリソースコントローラとSIP/SDP信号指示により通信し、前記リソースコントローラは、前記第1ユーザと第2ユーザと第3ユーザとの間の各呼区間に対する少なくともコーデック再ネゴシエーションおよびベアラ再構成を前記SIP/SDPベースのネットワークコントローラが独立して行うことを可能にする少なくとも1つのコーデックを前記ネットワークコントローラに提供し、前記リソースコントローラは、ベアラ経路リソースを、前記第1ユーザと前記第2ユーザと前記第3ユーザとの間の各呼区間に対する前記SIP/SDPベースのネットワークコントローラに通信し、前記ベアラ経路リソースは、インタネットプロトコルアドレス、使用可能なコーデック及び指向性のうちの少なくとも1つを含み、そして、
前記SIP/SDPベースのネットワークコントローラは、前記第1ユーザと前記第2ユーザと前記第3ユーザとの間の各呼区間に対するベアラ経路リソースについて同時に交渉する、装置。 - 前記ネットワークコントローラは、セッション記述プロトコルを用いて、RFC3725で定義されている第三者呼制御手順によりネットワークリソースの終端間の交渉を行う、請求項1に記載の装置。
- 前記ネットワークコントローラは、動作呼上にあり少なくとも前記第2ユーザに対して少なくとも1つの保留呼を有する前記第1ユーザからの要求に応じて、少なくとも前記第1ユーザおよび前記第2ユーザを少なくとも前記第3ユーザを伴う会議呼に接続し、前記装置はさらに前記リソースコントローラを含み、前記リソース・コントローラは、前記ユーザ間の各呼区間に対する少なくともコーデック再ネゴシエーションおよびベアラ再構成を前記リソースコントローラが行うことを許容するSIP/SDP信号指示により前記ネットワークコントローラに操作可能に接続されている、請求項1に記載の装置。
- 前記第1、第2および第3ユーザのうちの1つからの更なる要求に応じて、前記ネットワークコントローラは会議呼をクリアし、それによって、少なくとも前記第3ユーザを接続解除し、前記第1ユーザと前記第2ユーザとの間の二方向会話に対して動作呼を回復する、請求項3に記載の装置。
- 各ユーザが各SIPサーバに操作可能に接続され、前記各SIPサーバはSIP/SDP信号指示により前記ネットワークコントローラに操作可能に接続される、請求項3に記載の装置。
