Abstract
A method performed by a source access node for performing data forwarding at handover of a UE from a source cell to a target cell in a wireless communications network is provided. When a criterion for data forwarding is fulfilled, the source access node obtains a trigger for downlink data forwarding. When receiving the trigger, the source access node initiates downlink data forwarding to the UE via the target access node.
