Description
本願は、2011年3月3日に出願された米国仮特許出願第61/448,953号に基づく利益を主張し、この出願の開示全体を本明細書に引用により援用する。
本明細書に記載の主題は、ダイアメータ信号メッセージを、携帯電話加入者に関連付けられた情報を用いて修正することに関する。より具体的には、本主題は、ダイアメータシグナリングメッセージを強化するための方法、システム、およびコンピュータ可読媒体に関する。
現在、ダイアメータに基づくネットワークサービスノードの、一般的な携帯電話加入者に関連付けられたダイアメータシグナリングメッセージに対する割当には、問題がある。すなわち、ダイアメータに基づくネットワークサービスノード間の通信に関連する障害がある。たとえば、あるネットワークサービスノードが、一般的な携帯電話加入者に関連付けられダイアメータに基づくメッセージをサービスする別のネットワークサービスノードに関する追加情報(たとえばネットワークアドレス)を必要とする場合がある。このような状況では、ネットワークサービスノードが、上記ネットワークサービスノードに関する追加情報を格納しているデータベースノードに対して照会メッセージを生成し送信することを強いられる。こういった照会メッセージは、不必要なトラフィックを生じさせ、ネットワーク資源を消費する。よって、不必要なネットワークトラフィックを生じさせずにネットワークサービスノードに関する追加情報をプリエンプティブ(pre-emptive)方式で提供することが、ネットワークオペレータにとって望ましい。
ダイアメータシグナリングメッセージを強化するための方法、システム、およびコンピュータ可読媒体が開示される。ある代表的な実施の形態において、この方法は、携帯電話加入者に関連付けられ携帯電話加入者関連情報を含むダイアメータシグナリングメッセージを、ダイアメータルーティングノードで受信するステップと、上記携帯電話加入者関連情報を用いてダイアメータ結合リポジトリ(DBR)に照会することにより、上記ダイアメータシグナリングメッセージを処理するように構成された複数のネットワークサービスノードから1つのネットワークサービスノードを選択するステップとを含む。この方法はさらに、上記携帯電話加入者に関連付けられたDBR情報をDBRから取得するステップを含み、DBR情報は、上記選択されたネットワークサービスノードに関連付けられた識別子を含む。この方法はさらに、上記ダイアメータシグナリングメッセージを修正してDBR情報の少なくとも一部をこのダイアメータシグナリングメッセージに含めるステップを含む。本明細書で使用される「ノード」という用語は、1つ以上のハードウェアプロセッサと、関連付けられたメモリとを含む、物理計算プラットフォームを意味する。
本明細書に記載の主題は、ダイアメータシグナリングメッセージを強化するための方法、システム、およびコンピュータ可読媒体を含む。本明細書で使用されるダイアメータという用語は、RFC3588によって規定されている、電気通信およびコンピュータネットワークが利用する認証(authentication)、認可(authorization)、およびアカウンティング(accounting)(AAA)プロトコルを意味する。ある実施の形態において、本主題は、特定の携帯電話加入者に関連付けられたダイアメータシグナリングメッセージを受信するダイアメータシグナリングルーティング(DSR)ノードを含む。受信されたダイアメータシグナリングメッセージは、ネットワーク課金機能ノード(たとえば課金データ機能(CDF)、ポリシーおよび課金ルール機能(PCRF)等)といった、特定の種類のネットワークサービスノードからの処理も必要とする場合がある。DSRノードは、ダイアメータシグナリングメッセージを受信するとダイアメータ結合リポジトリ(DBR)に照会し、好ましいネットワークサービスノードを決定して、受信したダイアメータシグナリングメッセージを処理するように、構成されてもよい。ある実施の形態において、照会メッセージがDBRをトリガし、格納されている結合記録を調べさせることによって、好ましいネットワークサービスノードが既に携帯電話加入者に割当てられている(すなわち「結合されている」)か否か判断されてもよい。本明細書で使用される結合記録は、割当てられたネットワークサービスノードと携帯電話加入者情報(たとえば識別子)との間に形成される1つ以上のアソシエーションを含む電子記録を含み得る。よって、DBRは、この結合記録の中に保存されているDBR情報を取得してDSRに与えてもよい。DSRは次に、上記好ましいネットワークサービスノードに向けられたダイアメータシグナリングメッセージを修正して上記受信したDBR情報の少なくとも一部をこのメッセージに含めてもよい。したがって、好ましいネットワークサービスノードに、追加携帯電話加入者情報、携帯電話加入者に関連付けられた追加セッション識別子、およびこの携帯電話加入者をサポートする他のネットワークサービスノードに関連付けられた識別/アイデンティティ/アドレス情報を含む、強化されたダイアメータシグナリングメッセージが与えられる。ある実施の形態において、本主題は、LTE(Long Term Evolution)ネットワークおよび/またはIMS(Internet protocol Multimedia Subsystem)ネットワークにおいて実現し得る。これに代えて、本主題は、本主題の範囲を超えない限り、他のネットワーク実現化例に導入されてもよい。
