Title: Handover procedures in a wireless communications system

Abstract: A wireless communications system having a radio access network (RAN). A wireless terminal is connected to a serving node in the RAN. The wireless terminal exchange messages with a serving node to support a handover to a target node in the RAN. The target node receives the hand over and provides to the wireless terminal the identity of one or more messages sent from the serving node to the target node that were not acknowledged by the wireless terminal. The wireless terminal provides information to the target node to prevent the retransmission of one or more stale messages following handover.
