The invention concerns methods, a device and computer program products for simplifyin handover back to a restricted local access point from an unrestricted global access point as well as to a device implementing a restricted local access point for provision in a wireless network and a wireless network. In the network (10) a restricted local access point (26) hands over a mobile station (32) to an unrestricted global access point (18) an provides data enabling the restricted local access point to be identified as a candidate access point. A device (18; 12) for simplifying handover back determines that the restricted local access point is a candidate for further handover based on this data and inform the mobile station about the restricted local access point via the unrestricted glob access point, Thereby hand over may be considered also to the restricted local access point in addition to other surrounding access points.
L'invention concerne des procédés, un dispositif et des produits-programmes informatiques visant à simplifier un transfert de retour vers un point d'accès local restreint à partir d'un point d'accès global non restreint (5), ainsi qu'un dispositif associé à un point d'accès local restreint dans un réseau sans fil, et un réseau sans fil. Dans le réseau (10), un point d'accès local restreint (26) exécute le transfert d'une station mobile (32) vers un point d'accès global non restreint (18) et génère des données permettant d'identifier le point d'accès local restreint comme point d'accès candidat. Un dispositif (18, 12) de simplification de transfert détermine que le point d'accès local restreint 0 est candidat au transfert en fonction desdites données et informe la station mobile sur le point d'accès local restreint via le point d'accès global non restreint. Le transfert peut ainsi être considéré vers le point d'accès local restreint en plus d'autres points d'accès voisins.
