Abstract:
1. A method for user equipment assisted handover in a wireless data packet communication system to avoid user data loss, comprising: transmitting over-the-air a Radio Link Control (RLC) status report from a user equipment (UE) to a target node, wherein the RLC status report indicates a receipt status of RLC Packet Data Units (PDUs) previously received from a serving source node; receiving in-transit RLC Packet Data Units (PDUs) from the target node based on the RLC status report prior to an acknowledgement of handover completion, wherein the in-transit RLC PDUs were previously transmitted from the serving source node to the target node and not received by the UE; and receiving next-in-sequence RLC PDUs from the target node based on a RLC downlink initialization message received by the target node from the serving source node.
