Patent ID: 8908640

Claim:
A method for handover between multi-carrier cells, comprising: receiving a measurement report triggered by an event submitted by a user equipment (UE); determining, according to the measurement report, to hand over the UE to corresponding carriers of different target evolved NodeBs (eNBs); and sending serial numbers (SNs) of data to be transferred and identifier information of target eNBs of other carriers to which the UE is handed over to the different target eNBs or a master target eNB of the different target eNBs; wherein the sending SNs of data to be transferred and identifier information of the target eNBs of other carriers to which the UE is handed over to the different target eNBs or a master target eNB of the different target eNBs comprises: sending the SNs of data to be transferred to the different target eNBs directly or separately, and sending the identifier information of the target eNBs of other carriers to which the UE is handed over to each different target eNB simultaneously, when a parallel relationship exists between each target eNB, and when the corresponding carriers of the different target eNBs carry the same service; sending different SNs of data to be transferred and the identifier information of the target eNBs of other carriers to which the UE is handed over to the different target eNBs according to quality of service (QoS) requirements of different services, when a parallel relationship exists between each target eNB, and when the corresponding carriers of the different target eNBs carry different services; and sending SNs of data to be transferred and identifier information of slave target eNBs of other carriers to which the UE is handed over to a master target eNB, when a master-slave relationship exists between the different target eNBs.
