Description
図4のステップAに示すように、LCSエージェント302は、位置特定サービス対応アプリケーションから位置特定要求(location request)を受け取るとすぐに、そのアプリケーションの認証を行うことができる。認証が成功した場合、LCSエージェント302は、LCSエージェントが関連付けられている要求元LCSマネージャ(Requesting−LCS Manager)(R−LCS Manager)304に、即時位置決定(immediate location fix)を求めるMLP位置特定要求を発行する。
要求元LCSマネージャ304は、LCSエージェント302を認証し、受け取ったIcs−client−idに基づいて、LCSエージェント302にそれが要求するサービスについての権限が与えられていることを確認する。
位置特定要求を受け取るとすぐに、契約先LCSマネージャ306は、加入者のプライバシー(Privacy)をその要求で受け取ったIcs−client−id、requestor−id、qosなどに対して適用する。このユースケースでは、プライバシー・チェックは成功したものと仮定する。LCSマネージャ306がその適用を承認していない場合は、ステップNに適用MLP戻りコード(applicable MLP return code)が返される。
通知/確認(Notification/Verification)が必要とされる場合、UEのポップアップ・テキストを使って、加入者に、誰が加入者の位置情報(location info)、例えばIcs−client−id、requestor−id、request−typeなどを要求しているかを通知することができる。任意選択で、加入者がその位置特定要求を承諾することも、あるいはその位置特定要求を拒否することもできるようにすることもできる。
ステップDで対象加入者が位置特定要求を拒否している場合、ステップLに適用MLP戻りコードが返される。この場合、ステップEからKは省略される。そうでない場合、H−LCSマネージャ306は、対象UE 312から(または別のメカニズムを介して)のセル情報を使って、対象UE 312がローミングしていると判定することができる。関連するローミング契約に基づいて、あるいはIETF RFC 2916と同様のDNS検索メカニズムを用いて、H−LCSマネージャ306は在圏先LCSマネージャ308を識別することができ、在圏先LCSマネージャ308に対して、メッセージ・トンネリング・メカニズムがこの遷移に使用されることを表すインジケータを含むLr要求を開始する。
Lr要求を受け取ると、在圏先LCSマネージャ308は、対象UE 312が現在置かれているエリアでサービスを実行している測位サーバ310に対して、任意選択のセル情報、NMR、device capなどを含む、位置要求(Position Request)(PREQ)を開始する。
測位サーバ310は、V−LCSマネージャ308に位置応答(Position Response)(PRESP)を戻し、測位サーバ310がsessionidによって識別された位置特定要求を処理する準備ができていることを確認する。
位置応答メッセージを受け取るとすぐに、V−LCSマネージャ308は、H−LCSマネージャ306にLr応答メッセージを送る。Lr応答メッセージは、例えば測位サーバ310のIPアドレス(URL)を含むことができる。
サービスを実行している測位サーバ310からPRESPメッセージの確認を受け取るとすぐに、H−LCSマネージャ306は、対象UE 312に、サービスを実行している測位サーバ310と対象UE 312の間での直接通信が必要とされる場合には非ローミング・シナリオ用に、V−測位サーバではなくHLCSマネージャ306のアドレスを、また任意選択のposmodeを含む、位置特定開始応答(Start Location Response)(SLRESP)メッセージを送る。
関連するUE 312のローミングが検出されるとすぐに、対象UE 312はH−LCSマネージャ306に対して、位置決定(position determination)、例えば位置決定開始(Position Determination Initiation)(PDINIT)およびsessionidを開始する。PDINITメッセージは、任意選択で追加情報、例えばcell id、ad、および/またはIS−801 PDUを含む。
このメッセージを受け取ると、H−LCSマネージャ306は、関連するLr接続を介してV−LCSマネージャ308に、位置データ(Position Data)・メッセージに入れて、sessionidに対応するPDINITメッセージを送る。
V−LCSマネージャ308は、サービスを実行している測位サーバ310に、受け取った位置データ・メッセージを送る。
測位サーバ310および対象UE 312は、ステップJ、KおよびLで示した位置データに封入して位置決定メッセージング(Position Determination Messaging)(PDMESS)メッセージをH−LCSマネージャ306およびV−LCSマネージャ308を介して交換することによって、正確な測位手順を開始する。
測位サーバ310は、R/H/V−LCSマネージャ304、306、308に、対象UE 312からの決定された位置情報を含む、位置報告(Position Report)(PRPT)を送ることができる。
位置報告(PRPT)から必要とされる位置推定値(position estimates)を受け取るとすぐに、在圏先LCSマネージャ308は、Lr応答メッセージを使って、契約先LCSマネージャ306にその位置推定値を送る。
位置推定値が対象加入者のプライバシー設定により認められている場合、契約先LCSマネージャ306は要求元LCSマネージャ304にその位置推定値を送る。
最後に、要求元LCSマネージャ304が、LCSエージェント302に、位置推定値を含むMLP SLIAメッセージを戻す。

測位サーバ310および対象UE 312は、位置データ・メッセージに封入した位置決定メッセージング(PDMESS)メッセージをH−LCSマネージャ306およびV−LCSマネージャ308を介して交換することによって、正確な測位手順を開始する。
ステップFで、要求された位置推定値を受け取るとすぐに、在圏先LCSマネージャ308は、Lr応答メッセージを使って、契約先LCSマネージャ306にその位置推定値を送る。
位置推定値が対象加入者のプライバシー設定により認められている場合、契約先LCSマネージャ306は要求元LCSマネージャ304にその位置推定値を送る。
最後に、要求元LCSマネージャ304が、LCSエージェント302に、位置推定値を含むMLP SLIAメッセージを戻す。
