摘要： A method of a mobile station receiving data packets from a serving base station via a multicast or broadcast connection in a wireless network is provided for performing a handover from the serving base station to a target base station. The method comprises, at the level of the mobile station, the steps of: upon the detection of the quantity of buffered data packets in the mobile station being lower than a first threshold value, establishing a unicast connection with the serving base station to receive data packets from the serving base station; and upon detection of the level of buffered data packets reaching the predetermined threshold level, performing a handover from the serving base station to the target base station. According to the invention, a seamless handover of a mobile station in a wireless network providing Multicast and Broadcast Service (MBS service) can be achieved to prevent the MBS service interruption during the handover.
