A method and apparatus for handling network jitter in a Voice-over IP communications network using a virtual jitter buffer and time scale modification. A sequence of voice packets is received, where the sequence of voice packets may comprise a talk spurt, and the packets are stored in a jitter buffer having an initial playback latency of zero. Then, a number of the initial voice packets in the sequence are advantageously time-expanded and played out, thereby increasing the depth of the jitter buffer (and thus the amount of network jitter handled). Then, a number of subsequent voice packets are advantageously time-compressed and played out to return the jitter buffer depth to zero. In one embodiment, the sequence of voice packets comprises a talk spurt, and in another embodiment, the sequence of voice packets comprise those which are received during a cellular handoff.
A method for handling network jitter at a receiver in a communications network, the receiver having a jitter buffer for storing a sequence of frames of voice data comprised in a corresponding sequence of voice packets received over the communications network, the method comprising the steps of:
A packet receiver for handling network jitter in a communications network, the receiver comprising:
