Title
(EN) SERVICE CONTINUITY FOR MULTIMEDIA BROADCAST MULTICAST SERVICE (MBMS) FOR USER EQUIPMENT (UE) IN RRC CONNECTED MODE
(FR) CONTINUITÉ DE SERVICE POUR UN SERVICE DE DIFFUSION/MULTIDIFFUSION MULTIMÉDIA (MBMS) DESTINÉ À UN ÉQUIPEMENT UTILISATEUR (UE) EN MODE CONNECTÉ RRC
Abstract
(EN) A method is provided for a UE to receive a MBMS. The method includes, when the UE initiates a handover from a first cell that is providing the MBMS, the UE adding a TMGI associated with the MBMS service to a message sent from the UE to an access node in the first cell. The method further comprises the UE receiving information from the access node in the first cell, the information promoting the UE being handed over to a second cell capable of providing the MBMS.
(FR) Un procédé ci-décrit permet à un UE de recevoir un MBMS. Selon ledit procédé, lorsque l'UE commence un transfert intercellulaire à partir d'une première cellule qui fournit à ce moment le MBMS, il ajoute une TMGI associée au service MBMS à un message qu'il envoie à un nœud d'accès dans la première cellule. Ledit procédé comprend en outre la réception par l'UE d'informations en provenance dudit nœud d'accès dans la première cellule, ces informations facilitant le transfert intercellulaire de l'UE vers une seconde cellule qui peut fournir le service MBMS.
