Title
(EN) METHOD AND WIRELESS DEVICE FOR HANDLING HANDOVER
(FR) PROCÉDÉ ET DISPOSITIF SANS FIL DE GESTION DE TRANSFERT INTERCELLULAIRE
Abstract
(EN)
A method and a wireless device (100) for handling handover in a wireless network (102) from a source cell (104) to a target cell when the device has obtained and stored a handover configuration for at least one target cell X (106A-C). Upon detecting a communication failure, the wireless device (100) performs cell selection and initiates handover to one of the target cell(s) X when that cell wasselected, by applying the stored handover configuration of the selected cell. When none of the target cell(s) X was selected in the cell selection, the wireless device (100) initiates an RRC re-establishment procedure.(Fig. 1)
(FR)
La présente invention concerne un procédé et un dispositif sans fil (100) pour gérer un transfert intercellulaire dans un réseau sans fil (102) d'une cellule source (104) à une cellule cible lorsque le dispositif a obtenu et stocké une configuration de transfert pour au moins une cellule cible X (106A-C). Lors de la détection d'une défaillance de communication, le dispositif sans fil (100) effectue une sélection de cellule et déclenche un transfert vers une ou l'une des cellules cibles X lorsque cette cellule a été sélectionnée, en appliquant la configuration de transfert mémorisée de la cellule sélectionnée. Lorsqu'aucune des cellules cibles X n'a été sélectionnée dans la sélection de cellule, le dispositif sans fil (100) déclenche une procédure de rétablissement RRC. (Fig. 1)
