Abstract
(EN) The present invention proposes a device, comprising a control module configured to control a communication module, the communication module being controlled to communicate with a terminal in association with at least a first other device, using at least two carriers, wherein at least a first carrier towards the terminal is established from the device and at least a second carrier is established towards the terminal from the first other device; and wherein the control module is configured to receive of a report indicative of a connection quality of the first carrier, responsive thereto a issue a request for handover of the first carrier towards a second device, send a relocation information in relation to the first carrier towards the first other device, and only after sending that relocation information, command the terminal to perform a handover of the first carrier to the second device. Such device, in cooperation with other devices, accomplishes an optimized handover in terms of a primary component carrier relocation from a serving eNB towards a target eNB, while a secondary component carrier is maintained.
(FR) La présente invention concerne un dispositif, comprenant un module de commande configuré pour commander un module de communication, le module de communication étant commandé pour communiquer avec un terminal en association avec au moins un premier autre dispositif, à l'aide d'au moins deux porteuses, au moins une première porteuse vers le terminal étant établie depuis le dispositif et au moins une seconde porteuse étant établie vers le terminal depuis le premier autre dispositif; et le module de commande étant configuré pour recevoir un rapport indiquant une qualité de connexion de la première porteuse, en réponse à une demande émise de transfert de la première porteuse vers un second dispositif, pour envoyer une information de déplacement par rapport à la première porteuse vers l'autre premier dispositif, et seulement après l'envoi des informations de déplacement, pour commander au terminal d'effectuer un transfert de la première porteuse vers le second dispositif. Un tel dispositif, en coopération avec d'autres dispositifs, accomplit un transfert optimisé en termes de déplacement de porteuse de composante primaire d'un nœud b évolué (eNB) de desserte vers un eNB cible, tandis qu'une porteuse de composante secondaire est maintenue.
