FIELD: radio engineering, communication.
SUBSTANCE: technical key points of the present invention are as follows: before the base station controller receives a message sent by the serving GPRS support node (SGSN) to request the confirmation of a cell update of a mobile station (MS), the packet data of the first cell, initially meant to be sent to the MS, are transferred to a temporary block flow (TBF) between the MS and a second cell, and then sent to the base station (BTS) of the second cell via the TBF and then sent to the MS by the base station of the second cell.
EFFECT: effectively reducing packet data loss when a station moves from a first cell to a second cell.
