Abstract:
1. A method for inter-Node B handover in a carrier aggregation scenario, comprising: sending, by a target evolved Node B (eNB), a Handover Request Acknowledge message including handover reference frequency point information to a source eNB; sending, by the source eNB, a handover command including the handover reference frequency point information to a user equipment; and requesting, by the user equipment which is in a connected mode, a random access according to the center frequency point information of the uplink component carrier; wherein the handover reference frequency point information comprises center frequency point information of an uplink component carrier designated for the user equipment to initiate a random access request; and wherein the Handover Request Acknowledge message further includes frequency point and bandwidth information of all component carriers of the target cell of the target eNB.
