ABSTRACT:
A method for reconfiguring size of a receiving window in a communications system avoiding duplicate packet delivery to an upper layer to keep ciphering parameters in synchronization when the communications system reconfigures a receiving window of a receiver includes receiving a command for reconfiguring a size of the receiving window, reconfiguring the size of the receiving window according to the command, removing packets with sequence numbers outside the receiving window from buffers of the receiver and delivering the packets to the upper layer, determining whether a sequence number of a next expected packet is below the receiving window, and keeping the sequence number of the next expected packet and the packets in a reordering buffer of the receiver unchanged when the sequence number of the next expected packet is not below the receiving window.
