Title
(EN) METHOD AND SYSTEM FOR MACRO BASE STATION TO WFAP HANDOVER
(FR) PROCÉDÉ ET SYSTÈME DE TRANSFERT DE MACROSTATION DE BASE À WFAP
Abstract
(EN)
In a WiMAX handover process, the serving macro base station becomes aware of a list of viable target WFAPs for the mobile station upon the entry of the mobile station into the serving base station. The serving base station uses this information to trigger base station initiated scanning and handover to the appropriate WFAP. Whenever the WFAP Mgmt System server is updated with the CSG Information for the given mobile station, the corresponding H-AAA server of the mobile station is also updated by the WFAP Mgmt System server with the latest CSG configuration information. The serving BS then receives the CSG white list during MS INE from MS-AAA server.
(FR)
Selon l'invention, dans un processus de transfert WiMAX, la macrostation de base de desserte est avertie d'une liste de WFAP cibles viables pour la station mobile lors de l'entrée de la station mobile dans la station de base de desserte. La station de base (BS) de desserte utilise ces informations pour déclencher un balayage et un transfert au WFAP approprié à l'initiative de la station de base. Chaque fois que le serveur de système de gestion de WFAP est mis à jour avec les informations CSG pour la station mobile donnée, le serveur H-AAA correspondant de la station mobile est également mis à jour par le serveur de système de gestion de WFAP avec les informations de configuration CSG les plus récentes. La station de base de desserte reçoit également la liste blanche CSG durant une entrée initiale en réseau (INE) de la station mobile (MS) en provenance du serveur AAA de la station mobile.
