Abstract

La présente invention concerne un procédé, un appareil et un système pour rapporter des résultats de balayage, le procédé comprenant les étapes suivantes : une MS reçoit le message comprenant les informations sur l'identité de la station de base (BS ID) envoyées par une BS ; ladite MS définit le champ indiquant la séquence BS ID dans le message de rapport de balayage mobile (MOB_SCN_REP) et envoie ledit message MOB_SCN_REP à la BS afin de rapporter les résultats de balayage ; ledit champ indiquant la séquence BS ID établit une correspondance avec les informations BS ID. Le procédé, l'appareil et le système décrits ci-dessus permettent d'améliorer nettement l'efficacité d'utilisation des ressources d'interface d'air d'un système d'accès sans fil haut débit.
