Abstract

La présente invention se rapporte au domaine des communications. Des modes de réalisation de la présente invention concernent un procédé, un dispositif et un système pour ajouter une cellule voisine, de façon à améliorer le taux de réussite de transfert intercellulaire d'un terminal. Le procédé comprend les opérations suivantes : une première station de base acquiert des informations de cellule voisine d'une seconde cellule, la seconde cellule étant une cellule gérée par une seconde station de base ; la première station de base détermine, selon les informations de cellule voisine de la seconde cellule, si une première cellule existe ou non dans des cellules voisines de la seconde cellule, la première cellule étant une cellule gérée par la première station de base ; et ajouter la seconde cellule comme cellule voisine de la première cellule lorsque la première cellule existe dans les cellules voisines de la seconde cellule et que la seconde cellule n'existe pas dans des cellules voisines de la première cellule. Les modes de réalisation de la présente invention peuvent s'appliquer au scénario d'ajout d'une cellule voisine dans des communications mobiles.
