APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT PROVIDING AVOIDANCE OF DATA DUPLICATION DURING PACKET SWITCHED HANDOVER

摘要

A method for handling PDUs in a handover is described. The method includes receiving a PDU from a network element. The PDU is transmitted in conjunction with an indicator to a MS. The indicator indicates whether the MS is required to check if the transmitted PDU is a duplicate of a previously transmitted PDU. The method also includes receiving a PDU from the network element. There is a determination made of whether a check of the received PDU is required. If the check is required a determination of whether the received PDU is a duplicate of a previously received PDU is made. If the received PDU is a duplicate it is discarded. If the received PDU is not a duplicate the received PDU is forwarded for processing. An apparatus is also described.
