Abstract

La présente invention concerne un procédé, un dispositif et un appareil de commutation sectorielle. Le procédé peut être appliqué à un système de communication sans fil, le système de communication sans fil comprenant une cellule fusionnée, la cellule fusionnée comprenant au moins deux secteurs, et lesdits deux secteurs comprenant une fréquence porteuse fusionnée et une fréquence porteuse non fusionnée. Le procédé consiste à : évaluer si des informations d'état concernant un équipement d'utilisateur d'une fréquence porteuse non fusionnée d'un secteur de desserte satisfont, ou non, à une condition de commutation prédéfinie, le secteur de desserte étant un secteur quelconque d'au moins deux secteurs ; et, dans l'affirmative, notifier à l'équipement d'utilisateur d'accéder à une fréquence porteuse fusionnée d'une cellule fusionnée, acquérir un premier niveau de réception de liaison montante de l'équipement d'utilisateur dans au moins deux secteurs, et lorsqu'un secteur cible de l'équipement d'utilisateur est déterminé conformément au premier niveau de réception de liaison montante, notifier à l'équipement d'utilisateur d'accéder à une fréquence porteuse non fusionnée du secteur cible. Le procédé selon les modes de réalisation de la présente invention est utilisé pour résoudre le problème technique de l'état de la technique faisant que la communication normale d'un utilisateur est affectée en raison d'une interruption de transmission de données provoquée au cours du traitement de l'équipement d'utilisateur qui consiste à effectuer une resélection de cellule.
