Le mode de réalisation de la présente invention porte sur un procédé et un appareil pour un ajout de cellule voisine. Le procédé selon la présente invention comprend : une station de base recevant un rapport de mesure rapporté par un équipement utilisateur UE dans une première cellule commandée par la station de base, le rapport de mesure transportant les informations d'identification d'une seconde cellule, la première cellule et la seconde cellule étant des cellules inter-RAT (technologie d'accès inter-radio); la station de base envoyant à un dispositif de commande centralisé un message de demande utilisé pour demander l'identification de centre de commutation mobile MSCID de la seconde cellule et transportant l'identification de la seconde cellule; la station de base recevant la MSCID de la seconde cellule renvoyée par le dispositif de commande centralisé selon l'identification de la seconde cellule; et la station de base ajoutant la seconde cellule en tant que cellule voisine. Selon le procédé, la MSCID de la seconde cellule est obtenue durant le processus d'ajout de cellule voisine, qui assure que lorsque l'UE a besoin de déclencher des services vocaux après que la seconde cellule est ajoutée en tant que cellule voisine, un centre de commutation mobile (MSC) correspondant peut être atteint pour permettre à un repli à commutation de circuit (CSFB) d'être réalisé normalement.
