Abstract:
1. A method of a target Base Station (BS) performing handover in a multiple component carrier system, the method comprising: receiving service state information, including information about at least one candidate cell, from a source BS through a handover request message; calculating a final determination value for determining a final cell for a User Equipment (UE) which is a subject of the handover based on the service state information; selecting the final cell by comparing the final determination value and the information about the candidate cell; and sending a handover request Acknowledgment (ACK) message, including information about the selected final cell, to the source BS, wherein the service state information comprises at least one of a Guaranteed Bit Rate (GBR) which is a minimum bit rate for guaranteeing Quality of Service (QoS) of the UE, an Aggregated Maximum Bit Rate (AMBR) which is a maximum bit rate for guaranteeing the QoS of the UE in relation to bearers other than a bearer to which the GBR is applied, and an Average Throughput (AT) of packets for guaranteeing the QoS of the UE.
