Abstract

La présente invention concerne un procédé, un appareil et un dispositif de découverte et de connexion à un dispositif d'accès souple, et un support de stockage. Le procédé comprend : la réception d'un message de diffusion sur une première liaison, un élément d'information multiliaison inclus dans le message de diffusion comprenant un identifiant de la première liaison ; l'envoi d'un message de demande de sondage sur la première liaison, un élément d'information multiliaison inclus dans le message de demande de sondage comprenant l'identifiant de la première liaison ; recevoir un message de réponse de sonde sur la première liaison, un élément d'information multiliaison inclus dans le message de réponse de sonde comprenant des informations d'un point d'accès sur la première liaison et des informations d'un point d'accès sur une seconde liaison ; envoyer un message de demande de connexion sur la première liaison ; recevoir un message de réponse de connexion sur la première liaison ; et définir une liaison primaire et une liaison non primaire en fonction du message de réponse de connexion. Grâce à la présente invention, la perte de paquets causée par l'interférence d'émission-réception asynchrone sur deux points d'accès logiques peut être évitée, la zone de couverture d'un réseau sans fil est étendue, le taux de transmission des données est amélioré, et l'interférence entre les liaisons est également éliminée, ce qui réduit le taux de perte de paquets et garantit le taux de débit effectif du réseau.
