管理システム50は、送受信部51、認証部52、管理部53、セッション制御部58、及び記憶・読出部59を有している。これら各部は、図4に示されている各構成要素のいずれかが、HD204からRAM203上に展開された管理システム50用のプログラムに従ったCPU201からの命令によって動作することで実現される機能又は手段である。また、管理システム50は、HD204により構築される記憶部5000を有している。この記憶部5000には、アプリID毎に、アプリアイコンのデータが記憶されている。更に、記憶部5000には、以下に示すような各テーブルによって構成されているDB(5001,5002,5003,5005,5010,5012)が構築される。
図7Aは、認証管理テーブルを示す概念図である。記憶部5000には、図7Aに示されているような認証管理テーブルによって構成されている認証管理DB5001が構築されている。この認証管理テーブルでは、管理システム50によって管理される全ての端末10の各通信IDに対して、認証用のパスワードが関連付けられて管理される。なお、通信IDは、コンテンツデータ用セッションにおいて、コンテンツデータの送信先(通信先)あるいは送信元(通信元)を識別するための情報である。通信IDには、例えば、端末10を識別する情報、端末10のユーザを識別する情報、複数の端末10によって構成されるグループを識別する情報等が含まれる。以下、通信IDが、端末10を識別する情報、又はグループを識別する情報である場合について説明する。
図7Bは、端末管理テーブルを示す概念図である。記憶部5000には、 図7Bに示されているような端末管理テーブルによって構成されている端末管理DB5002が構築されている。この端末管理テーブルでは、各端末10の通信ID毎に、各端末10を宛先とした場合の宛先名(端末名)、各端末10の稼動状態、及び各端末10のIPアドレスが関連付けられて管理される。なお、稼働状態「OFFライン」は、管理システム50と接続していない状態を示す。稼働状態「ONライン(通信可能)」は、管理システム50と接続しているが、他の端末10と通信していない状態を示す。稼働状態「ONライン(通信中)」は、管理システム50と接続して、他の端末10と通信しているが、通信相手の端末10のコンテンツデータを受信していない状態を示す。稼働状態「ONライン(通話中)」は、管理システム50と接続して、他の端末10と通信しており、通信相手の端末10のコンテンツデータを受信している状態を示す。
図7Cは、アプリ利用可否管理テーブルを示す概念図である。記憶部5000には、図7Cに示されているようなアプリ利用可否管理テーブルによって構成されているアプリ利用可否管理DB5003が構築されている。このアプリ利用可否管理テーブルでは、端末10の通信ID及びこの端末10にインストールされている複数のアプリのそれぞれを識別するためのアプリID毎に、この端末10でそれぞれのアプリが利用可能(On)又は利用不可能(Off)を示す利用可否情報を関連付けて管理している。
図7Dは、セッション管理テーブルを示す概念図である。記憶部5000には、図7Dに示されているようなセッション管理テーブルによって構成されているセッション管理DB5005が構築されている。このセッション管理テーブルでは、端末10間でコンテンツデータが送信されるセッションを識別するためのセッションID毎に、このセッションにおいて、端末10間でコンテンツデータを中継する中継装置30の中継装置ID、このセッションに参加している端末10(参加端末)のうちコールセンター(オペレータ)側の参加端末の通信ID、オペレータ側の参加端末の通信相手となるカスタマー側の参加端末の通信IDが関連付けられて管理される。
図7Eは、グループ情報管理テーブルを示す概念図である。記憶部5000には、図7Eに示されているようなグループ情報管理テーブルによって構成されているグループ情報管理DB5010が構築されている。このグループ情報管理テーブルでは、グループを識別するための通信IDと、そのグループを通信宛先とするときの宛先名(グループ名)と、そのグループを構成する各端末10の各通信IDと、を関連付けて管理する。
図7Fは、待機情報管理テーブルを示す概念図である。記憶部5000には、図7Fに示されているような待機情報管理テーブルによって構成されている待機情報管理DB5012が構築されている。この待機情報管理テーブルでは、オペレータ側の参加端末の通信IDに対して、このオペレータ側の参加端末との通信を待機しているカスタマー側の待機端末の通信ID、及びオペレータ側の参加端末との通信の開始要求を管理システム50側で受け付けた受付時刻が関連付けられて管理される。
次に、管理システム50の各機能構成について詳細に説明する。なお、以下では、管理システム50の各機能構成を説明するにあたって、図4に示されている各構成要素のうち、管理システム50の各機能構成を実現させるための主な構成要素との関係も説明する。
以上が、通信システム1の構成及び機能(又は手段)の説明であり、続いて、通信システム1における処理方法を説明する。
管理システム50(送信制御システムの一例)のセッション制御部58(送信制御手段の一例)は、端末10間でコンテンツデータを送信するためのコンテンツデータ用セッションsedにおいて、一以上の端末(10aa,10ab)のそれぞれから端末10db(第1の通信端末の一例)へコンテンツデータが送信される一方で、端末10dbから一以上の端末(10aa,10ab)のうち少なくとも端末10aa(第2の通信端末の一例)へ、コンテンツデータが送信されないように制御する。続いて、端末10aaによる要求に基づいて、セッション制御部58は、端末10dbから端末10aaへコンテンツデータが送信されるように制御する。これにより、端末(10aa,10db)間で双方向にコンテンツデータが送信されるので、端末(10aa,10db)の各ユーザ間で通話を開始できる。また、上記のように、通話を開始する前から、端末10aaから送信されるコンテンツデータを端末10dbに送信することで、端末10aa側の状況が端末10db側へ伝達されるようになる。これにより、端末10db側では通話の要求元の状況に応じた通話の準備をすることが可能になる。
上記各実施の形態における管理システム50、及びプログラム提供システム90は、単一のコンピュータによって構築されてもよいし、各部(機能又は手段)を分割して任意に割り当てられた複数のコンピュータによって構築されていてもよい。また、プログラム提供システム90が単一のコンピュータによって構築されている場合には、プログラム提供システム90によって送信されるプログラムは、複数のモジュールに分けて送信されるようにしてもよいし、分けないで送信されるようにしてもよい。更に、プログラム提供システム90が複数のコンピュータによって構築されている場合には、複数のモジュールが分けられた状態で、各コンピュータから送信されるようにしてもよい。
