Abstract
【解決手段】少なくとも1つのセルラネットワーク(110)と、少なくとも1つのWLAN(130a、130b)と、IPネットワーク(140)とが展開される。最初に、無線送受信ユニット(WTRU;102)は、WLAN(130a)との接続を確立し、アクセスポイント(AP;132a)とパケットデータゲートウェイ(PDG;129)との間でトンネルが確立される。PDG(129)は、IPネットワーク(140)とのトンネルをさらに確立する。次いで、WTRU(102)は、WLAN(130a)を介して配信されるサービスを呼び出す。AP(132a)からの信号品質が予め定められた閾値よりも下回った場合、WLAN(130a)からセルラネットワーク(110)へのハンドオーバが実行される。
【選択図】図1
Description
1.IMSによって提供されるユーザサービスがハンドオーバ後もセルラネットワークを介して継続的に提供される、当該ユーザサービスのためのセルラネットワークとWLANとの間のインターワーキング方法。最初に、WTRUはWLANとの接続を確立し、WLANと、セルラネットワークのPDGとの間にトンネルを確立し、続いて、PDGとIPネットワークとの間にトンネルを確立して、WLANを介してユーザサービスを受信する。WTRUはセルラネットワークとの接続を確立し、WLANを介してハンドオーバ信号を送信することによって、WLANからセルラネットワークへのハンドオーバを実行する。
Claims (3)

前記第1のRANから前記第2のRANへの前記音声電話サービスのハンドオーバーを開始するステップと、
前記ハンドオーバー中に前記音声電話サービスを前記IMSから連続的に受信しながら、前記ハンドオーバーを実行し、および、前記セルラーネットワークへの接続を同時に維持しながら、前記第1のRANへの接続を維持するステップと
を含むことを特徴とする方法。 - 前記第1のRANは、無線ローカルエリアネットワーク(WLAN)であることを特徴とする請求項1に記載の方法。
- 前記ハンドオーバーを開始するステップは、トンネルエンドポイント識別子、ユーザの識別子、無線リソース情報、周波数チャネル情報、優先度情報の少なくとも1つを含む表示を送信するステップを含むことを特徴とする請求項1に記載の方法。
