METHOD FOR PERFORMING HANDOVER PROCEDURE AND CREATING DATA

摘要

A method is described of performing handover by a mobile terminal from a source base station to a target base station, the mobile terminal having a Radio Resource Control (RRC) layer and a Radio Link Control (RLC) layer. The RRC layer receives a handover command. The RLC layer receives an indication associated with the handover command. Upon receiving the indication, at least one RLC service data unit (SDU) from at least one protocol data unit (PDU) having a sequence number that is less than a variable is reassembled. The variable indicates a sequence number following a highest sequence number among at least one PDU received out of sequence by the RLC layer. The reassembled at least one RLC SDU is delivered to an upper layer of the mobile terminal, and at least one remaining PDU that could not be reassembled into at least one RLC SDU is discarded.

1. A method of performing handover by a mobile terminal from a source base station to a target base station, the mobile terminal having a Radio Resource Control (RRC) layer and a Radio Link Control (RLC) layer, the method comprising:
receiving, at the RRC layer, a handover command; receiving, at the RLC layer, an indication associated with the handover command; upon receiving the indication, reassembling, at the RLC layer, at least one RLC service data unit (SDU) from at least one protocol data unit (PDU) having a sequence number that is less than a variable, wherein the variable indicates a sequence number following a highest sequence number among at least one PDU received out of sequence by the RLC layer; delivering, at the RLC layer, the reassembled at least one RLC SDU to an upper layer of the mobile terminal; and discarding, at the RLC layer, at least one remaining PDU that could not be reassembled into at least one RLC SDU.
