Abstract
A device communicates 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. The device receives a report indicative of a connection quality of the first carrier, responsive thereto issues a request for handover of the first carrier towards a second device, sends relocation information in relation to the first carrier towards the first other device, and only after sending that relocation information, commands 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.
