Title (EN) DEVICES AND METHOD OF EVOLVED MULTIMEDIA BROADCAST MULTICAST SERVICE HANDOVER
(FR) DISPOSITIFS ET PROCÉDÉ DE TRANSFERT INTERCELLULAIRE DE SERVICE DE MULTI-DIFFUSION/DIFFUSION MULTIMÉDIA ÉVOLUÉ
Abstract:
(EN) Devices and methods of limiting eMBMS service disruptions during handover are generally described. The UE may transmit to a serving eNB TMGIs of ongoing and interested eMBMS services for the UE. The UE may receive a RRCConnectionReconfiguration message that includes a MBSFN subframe configuration list of a target eNB for at least the eMBMS services identified by the TMGIs and establish the eMBMS services at the target eNB based thereon. The RRCConnectionReconfiguration message may include all eMBMS allocations in all MBSFN areas and a subframe configuration list for all eMBMS services in all areas, as well as eNB and target eNB MSI information and MSI validity timing. If the target eNB MSI will be invalid when handover of the UE is completed, the UE may request from the target eNB the target eNB MSI on dedicated signaling.
(FR) Selon la présente invention, des dispositifs et des procédés de limitation des interruptions de service eMBMS au cours d'un transfert intercellulaire sont décrits de manière générale. L'UE peut transmettre à des TMGIs d'eNB de desserte des services eMBMS intéressés et en cours pour l'UE. L'UE peut recevoir un message de Reconfiguration de Connexion RRC qui comprend une liste de configuration de sous-trame MBSFN d'un eNB cible pour au moins les services eMBMS identifiés par les TMGI et établir les services eMBMS au niveau de l'eNB cible basé sur ce dernier. Le message de Reconfiguration de Connexion RRC peut comprendre toutes les attributions eMBMS dans toutes les zones MBSFN et une liste de configuration de sous-trame pour tous les services eMBMS dans toutes les zones, ainsi qu'un eNB et des informations MSI eNB cibles et une période de validité MSI. Si le MSI eNB cible n'est pas valide lorsque le transfert intercellulaire de l'UE est terminé, l'UE peut demander à l'eNB cible le MSI eNB cible sur une signalisation dédiée.
