Title (EN) HANDOFFS AND HANDOFF SELECTION IN A WIRELESS ACCESS NETWORK
(FR) TRANSFERTS ET SELECTION DE TRANSFERT DANS UN RESEAU D'ACCES SANS FIL
Abstract: front page image
(EN)The present invention facilitates handoffs for a mobile terminal in a wireless access network that is capable of supporting different types of handoffs. The different handoff types may include soft handoffs and fast base station switching (FBSS). In operation, context information associated with supporting wireless communications between the wireless access network and the mobile terminal are determined. Based on whether the context information is shared between base stations involved in the handoff or transferred from one base station to another of the base station involved in the handoff, a particular handoff type is selected from the different handoff types that are available. Selecting the specific type of handoff to use may also be based on the level of context information that is available, the actual content of the context information, application preferences, channel conditions, base station or mobile terminal capabilities, or any combination thereof.
(FR)La présente invention facilite les transferts pour un terminal mobile dans un réseau d'accès sans fil pouvant soutenir différents types de transferts. Ces différents types de transferts peuvent comprendre des transferts sans coupure et une commutation de station de base rapide (FBSS). En fonctionnement, des informations de contexte associées au soutien de communications sans fil entre le réseau d'accès sans fil et le terminal mobile sont déterminées. Selon si ces informations de contexte sont partagées entre les stations de base impliquées dans le transfert ou transférées d'une station de base à une autre station de base impliquée dans le transfert, un type de transfert particulier est choisi parmi les différents types de transferts disponibles. Le choix du type de transfert spécifique à utiliser peut également être déterminé par le niveau d'informations de contexte disponible, le contenu réel des informations de contexte, les préférences d'applications, les conditions de canaux, les capacités de station de base ou de terminal mobile, ou n'importe quelle combinaison de ces éléments.
