Title
(EN) METHOD FOR HANDOFF DURING CONNECTED MODE OF A MULTIMODE MOBILE STATION IN A MIXED DEPLOYMENT
(FR) PROCÉDÉ DE TRANSFERT EN MODE CONNECTÉ D’UNE STATION MOBILE MULTIMODE DANS UN DÉPLOIEMENT MIXTE
Abstract
(EN)
Methods for handoff of a multimode mobile station (MS). The MS, in connected mode, moves from a cell of a legacy base station to a cell of an ABS and scans base stations from a list of neighbouring base stations, wherein at least the ABS is listed as another legacy base station in the list of neighbouring base stations. The MS performs the handoff to connect to a legacy zone of the ABS. Further, the multimode MS switching from the legacy zone of the ABS to a advanced zone of the ABS based on a Zone Switch request or command is triggered by either the multimode MS or the ABS. The Zone Switch request is triggered after detecting capabilities of either the multimode MS or the ABS that they support advanced zone. The capabilities are detected by using MAC versions of the multimode MS and the ABS or an indicator for the advanced zone. The multimode MS can also performs handoff to the advanced zone from the cell of the legacy base station by receiving one or more information for ranging in the advanced zone from the ABS during the handoff.

L’invention concerne des procédés de transfert d’une station mobile multimode (MS). La MS, en mode connecté, se déplace d’une cellule d’une station de base récupérée à une cellule d’une ABS et explore les stations de base à partir d’une liste de stations de base voisines, au moins l’ABS étant mentionnée en tant qu’autre station de base récupérée dans la liste des stations de base voisines. La MS exécute le transfert pour se connecter à une zone récupérée de l’ABS. De plus, la MS multimode commutant de la zone récupérée de l’ABS à une zone évoluée de l’ABS sur la base d’une demande ou d’une commande de commutation de zone est déclenchée soit par la MS multimode soit par l’ABS. La demande de commutation de zone est déclenchée après la détection des capacités de la MS multimode ou de l’ABS à supporter la zone avancée. Les capacités sont détectées à l’aide des versions MAC de la MS multimode et de l’ABS ou d’un indicateur de la zone évoluée. La MS multimode peut également assurer le transfert à la zone évoluée, à partir de la cellule de la station de base récupérée, en recevant une ou plusieurs informations devant être incluses dans la zone avancée à partir de l’ABS pendant le transfert.
