Abstract:
(EN)
This base station gateway device has a C plane processor and a U plane processor. In a case where a mobile station does a handover from a controlled source base station to a controlled target base station, the C plane processor terminates S1AP signaling received from the source base station or the target base station, without relaying the S1AP signaling to a movement management device. Also, at a prescribed timing, the U plane processor inserts an end marker into U plane data received from a serving gateway device and transferred to the source base station, the end marker indicating that said U plane data is the last. Immediately after inserting the end marker, the U plane processor switches the transfer destination of the U plane data received from the serving gateway device from the source base station to the target base station.
(FR)
La présente invention concerne un dispositif passerelle de station de base comportant un processeur de plan C et un processeur de plan U. Dans un cas dans lequel une station mobile exécute un transfert d'une station de base source commandée vers une station de base cible commandée, le processeur de plan C met fin à une signalisation S1AP reçue de la station de base source ou de la station de base cible, sans relayer la signalisation S1AP à un dispositif gestionnaire de déplacement. En outre, à une synchronisation prescrite, le processeur de plan U introduit un marqueur de fin dans des données de plan U reçues d'un dispositif passerelle de service et transférées vers la station de base source, le marqueur de fin indiquant le fait que lesdites données de plan U sont les dernières. Immédiatement après l'introduction du marqueur de fin, le processeur de plan U commute la destination de transfert des données de plan U reçues du dispositif passerelle de service de la station de base source vers la station de base cible.

本発明の基地局ゲートウェイ装置は、Cプレーン処理部と、Uプレーン処理部と、を有する。Cプレーン処理部は、移動局が、配下のソース基地局から配下のターゲット基地局にハンドオーバする場合、ソース基地局及びターゲット基地局から受信したS1APのシグナリングを、移動管理装置にリレーせずに終端する。また、Uプレーン処理部は、所定のタイミングで、サービングゲートウェイ装置から受信しソース基地局に転送するUプレーンデータに、そのUプレーンデータが最後であることを示すエンドマーカーを挿入し、エンドマーカーを挿入した直後のタイミングで、サービングゲートウェイ装置から受信したUプレーンデータの転送先を、ソース基地局からターゲット基地局に切り替える。
