Description
簡単に説明すると、本発明はDNSドメイン名が複数のSIPドメインで用いられることを可能にするための仕組みを提供する。すなわち、DNSドメインが共有DNSドメインとして用いられることを可能にする仕組みを提案する。
Claims (20)
- ユーザデータベースクエリが失敗した(401)入来要求を処理するための、SIPドメイン(200)のノード(201)における方法であって、
前記要求のDNSドメイン名の全体が共有ドメインとして登録されているかどうかを判別するステップ(402)と、
前記DNSドメイン名の全体が共有ドメインとして登録されている場合に、前記DNSドメイン名をグローバルにルーティング可能なURIに解決するステップ(404)、及び、
前記DNSドメイン名の全体が共有ドメインとして登録されている場合に、前記要求を終端エンティティへルーティングするステップ(405)、又は、
前記DNSドメイン名の全体が共有ドメインとして登録されていない場合に、前記要求を拒否するステップ(403)と、
を有することを特徴とする方法。 - 前記判別するステップが、設定データを調べるステップを有することを特徴とする請求項1記載の方法。
- 前記設定データが、前記SIPドメインのオペレータが管理するすべてのDNSドメイン(301)と、個々のDNSドメインが共有ドメインか否かを示す、関連付けられたパラメータ(302)と、を有することを特徴とする請求項2記載の方法。
- 前記設定データが、各々が個々のDNSドメインを共有するSIPドメインを示す1つ以上のURI、を格納するためのポスト(303)をさらに有することを特徴とする請求項3記載の方法。
- 前記設定データが1つ以上のSIPドメイン名(501)を有する場合、当該SIPドメイン名を、前記DNSドメイン名をグローバルにルーティング可能なURIに解決する(502)際に用いることを特徴とする請求項4記載の方法。
- 前記設定データにおいて、共有DNSドメインとして登録されているSIPドメイン名がない場合、クエリを実行(503)した後で前記個々のDNSドメイン名が解決される(504)ことを特徴とする請求項2乃至請求項5のいずれか1項に記載の方法。
- 前記クエリがDNSクエリであることを特徴とする請求項6記載の方法。
- 前記ノードが呼セッション制御機能(CSCF)であることを特徴とする請求項1乃至請求項7のいずれか1項に記載の方法。
- 前記CSCFがインタロゲーティングCSCF(I-CSCF)であることを特徴とする請求項8記載の方法。
- 前記SIPドメインがIMSドメインであることを特徴とする請求項1乃至請求項9のいずれか1項に記載の方法。
- ユーザデータベースクエリ(2:2)が失敗した入来要求(2:1)を処理するための、SIPドメイン(200)のノード(201)であって、
前記失敗したユーザデータベースクエリに応答して、ドメインチェック手順(2:3b)を開始するクエリ手段(202)と、
前記要求のDNSドメイン名の全体が共有ドメインとして登録されているかどうかを判別するステップ(402)を有する前記ドメインチェック手順(2:4)、を実行するドメインチェック手段(205)であって、前記DNSドメイン名の全体が共有ドメインとして登録されている場合に、前記DNSドメイン名をグローバルにルーティング可能なURIに解決する(2:5a, 2:5b)ように適合されるとともに、前記DNSドメイン名の全体が共有ドメインとして登録されている場合に、前記要求を終端エンティティへルーティングする(2:6)ように適合されるか、前記DNSドメイン名の全体が共有ドメインとして登録されていない場合に、前記要求を拒否する(2:5c)ように適合される、ドメインチェック手段(205)と、を有することを特徴とするノード。 - 前記ドメインチェック手順が、前記ノードに保存されているか、前記ノードに関連付けられた、設定データを調べるステップを有することを特徴とする請求項11記載のノード。
- 前記設定データが、前記SIPドメインのオペレータが管理するすべてのDNSドメイン(301)と、個々のDNSドメインが共有ドメインか否かを示す、関連付けられたパラメータ(302)と、を有することを特徴とする請求項12記載のノード。
- 前記設定データが、各々が個々のDNSドメインを共有するSIPドメインを示す1つ以上のURI、を格納するためのポスト(303)をさらに有することを特徴とする請求項13記載のノード。
- 個々のDNSドメインを共有する1つ以上のSIPドメインが前記設定データに登録されている場合に、前記ドメインチェック手段が、前記設定データに従って、前記DNSドメイン名をグローバルにルーティング可能なURIに解決するように適合されることを特徴とする請求項12乃至請求項14のいずれか1項に記載のノード。
- 前記設定データにSIPドメインが登録されていない場合、前記ドメインチェック手段が、クエリを実行した後で前記DNSドメイン名を解決するように適合されることを特徴とする請求項12乃至請求項15のいずれか1項に記載のノード。
- 前記クエリがDNSクエリであることを特徴とする請求項16記載のノード。
- 前記ノードが呼セッション制御機能(CSCF)であることを特徴とする請求項11乃至請求項17のいずれか1項に記載のノード。
- 前記CSCFがインタロゲーティングCSCF(I-CSCF)であることを特徴とする請求項18記載のノード。
- 前記SIPドメインがIMSドメインであることを特徴とする請求項11乃至請求項19のいずれか1項に記載のノード。
