A method, performed in a long term evolution (LTE) communications network, of facilitating handover of a mobile communication device from a source node to a target node includes receiving, in the target node, downlink user data packets forwarded from the source node via a first interface, receiving, in the target node, downlink user packets from an external source via a second interface, buffering the received user data packets during handover prior to sending to the mobile communication device, ordering the downlink data packets in the target node based on the interface from which the data packets are received, and sending the ordered downlink data packets from the target node to the mobile communication device after completion of handover from the source node to the target node.
