METHOD FOR TRANSFERRING PACKET DATA IN WIRELESS NETWORK AND BASE STATION CONTROLLER

摘要

A method for transferring packet data in a wireless network and a base station controller (BSC) are provided in the present invention. The technical key points of the present invention are as follows: before the BSC has received the message which is sent by the Serving GPRS Support Node (SGSN) to request the confirmation of a cell update of the mobile station (MS), the packet data, which was to be sent to the MS by a first cell formerly, are transferred to the temporary block flow (TBF) between the MS and a second cell, and then, sent to the base transceiver station (BTS) of the second cell via the TBF between the MS and the second cell, and at last, 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 a cell update can be reduced.
