(EN) METHOD AND SYSTEM FOR PRIORITIZING CELL SELECTION
(FR) PROCÉDÉ ET SYSTÈME PERMETTANT DE HIÉRARCHISER LA SÉLECTION DE CELLULES
Abstract
(EN)
Methods and systems for prioritizing cell selection for availing LADN services. A UE prioritizes cells for selection based on availability of LADN services in the cells. For handover, a base station of a cell, providing LADN services to the UE, prioritizes target cells that provide LADN services that are being currently availed by the UE for ensuring LADN service continuity. The base station initiates addition of secondary cells that provide additional LADN services that are intended by the UE. The UE can predict if a paging message is relevant to a LADN service and send serving requests to the serving cell or other cells to avail the LADN service. The UE detects relay UEs providing LADN services and prioritizes the relay UEs for selection based on availability of LADN services. The UE buffers data if the UE is located at an edge of a LADN service area.

La présente invention concerne des procédés et des systèmes permettant de hiérarchiser la sélection de cellules pour l'utilisation de services LADN. Un UE priorise des cellules pour effectuer une sélection sur la base de la disponibilité de services LADN dans les cellules. Pour un transfert intercellulaire, une station de base d'une cellule, fournissant des services LADN à l'UE, priorise des cellules cibles fournissant des services LADN qui sont actuellement utilisés par l'UE pour assurer la continuité du service LADN. La station de base déclenche l'ajout de cellules secondaires qui fournissent des services LADN supplémentaires qui sont destinés à l'UE. L'UE peut prédire si un message de radiomessagerie est pertinent pour un service LADN et envoyer des requêtes de desserte à la cellule de desserte ou à d'autres cellules pour utiliser le service LADN. L'UE détecte des UE relais fournissant des services LADN et priorise les UE relais pour effectuer une sélection sur la base de la disponibilité des services LADN. L'UE met en mémoire tampon les données si l'UE est situé au bord d'une zone de service LADN.
