摘要

In voice packet communication in a radio communication system, reduction in voice reproduction quality at handover is prevented. A buffer memory (11) buffers voice packet data (step S1). When a predetermined amount of voice packet data is buffered, a transmitting unit (12) starts to transmit by radio the voice packet data to a mobile station (20) (step S2). Thereafter, when handover to a radio base station (10a) is determined, all or two or more of the buffered voice packet data are transmitted by radio to the mobile station (20) (step S3). The mobile station (20) continues voice reproduction at predetermined voice reproduction timing according to the received voice packet data also during handover processing.
