AbstractThe antimissing processing method for IP speech data packet is characterized by that in receiving terminal, when the time-delay flutter change amplitude of IP speech data packet is large, the length of buffer zone of IP speech data packet of receiving terminal can be adaptively increased, and when the above-mentioined flutter change amplitude is small, the length of the above-mentioned buffer zone can be adaptively reduced. By changing and regulating buffer zone size said invention can attain the goals of resisting time-delay flutter, preventing data packet from missing and improving quality of IP speed so as to solve the problem of that the network traffic flow change and difference of different routes can result in poor speech naturalness.
