A method for realizing fast handover in enhanced uplink is disclosed, which could be applied in Time Division Synchronous Code Division Multiple Access system. The method comprises the following steps: (a) when cell handover occurs for a user equipment (UE) and a network side determines that the UE can perform enhanced uplink service in the target cell, sending by the network side a handover command carrying information of random access resources of the target call to the UE; (b) after the UE completes the handover process, if there are data available for transmission in the buffer(s) corresponding to the enhanced uplink radio bearer(s), initiating by the UE an enhanced uplink random access according to the information of random access resources carried in the handover command to request scheduling resources from the base station Node B. The present invention can eliminate the delay of enhanced uplink service due to the need for reading out the cell broadcast information after the cell handover in the scheduling service of High Speed Uplink Packet Access, so as to realize fast handover. |
