Data transmission during handover

Abstract:

The present invention relates to handling data transfer during handover, whereby a terminal device is initially connected to a serving access node and a handover is performed to connect the terminal device to a target access node. The improved handling of data transfer is achieved by upon making a handover decision, performing data rerouting to the target access node while continuing to exchange data between the terminal device and the serving access node, and stopping the data exchange between the terminal device and the serving access node in response to an indicator indicating that the target access node is ready to proceed with the handover.
