Abstract
A handover process is proposed in a carrier aggregation scenario, in which there is encompassed a device communicating with a terminal in association with at least another device, using at least two carriers. At least a first carrier towards the terminal is established from the at least one another device and at least a second carrier is established towards the terminal from the device. A control module of the device is configured to suspend ongoing traffic between the device and the terminal on the second carrier, perform re-establishment of one or more protocol entities communicating over bearers between the device and the terminal on the second carrier, and resume traffic between the device and the terminal on the second carrier. The suspending is triggered by a first instruction received from a first one of the at least one another device, and the resuming is triggered by a second instruction received.
