A method for transferring packet data in a wireless network and a base station controller (BSC) thereof are provided in the present invention. The technical key points of the present invention are as follows: before the BSC receives the message sent by the Serving GPRS Support Node (SGSN) for requesting the acknowledgement of a cell update in the mobile station (MS), the packet data of a first cell to be originally sent to the MS is transferred to the temporary block flow (TBF) of the MS and a second cell, and is sent to the BTS of the second cell by the TBF of the MS and a second cell, as last, is sent to the MS by the BTS of the second cell. The packet data loss resulting from the MS moving from the first cell to the second cell can be effectively decreased, the normal data communication related to the MS can be ensured, and the retransmission rate of the packet data after the cell update can be reduced. |
