Method for realizing dynamic jitter buffer adaptive to network peak

Abstract

In the method, when starting network overshoot is determined, delay time value and average jitter value in network is calculated at time of network overshoot. Based on corresponding average jitter value in network and delay time value at network overshoot state, adjustment is carried out for depth of jitter buffer (JB) in order to suit requirement for depth of JB under network overshoot state. That is to say the invention can determine starting point and ending point of network overshoot period correctly. When time delay caused by network overshoot phenomena occurs in network, adjustment is carried out for depth of JB by using relevant algorithm in order to adapt to network overshoot state, reduce rate of packet loss. Thus, lowering quality of VOIP voice caused by continuous packet loss in overshoot period will not be happened. The invention guarantees quality of voice transmission in network, where overshoot phenomena occur frequently.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing a dynamic jitter buffer adapting to network spikes. Background technique [0002] With the continuous maturity of Internet (Internet) technology, it is possible to transmit traditional voice information on the Internet. Therefore, various technologies of VOIP (Voice over Internet Protocol) have emerged as the times require. Among them, Jitter Buffer (jitter buffer, referred to as JB) technology is one of the core technologies of VOIP. JB technology directly affects the voice quality of VOIP, especially in the case of poor network quality. [0003] JB technology is mainly divided into two categories: static JB technology and dynamic JB technology. At present, the inherent delay, jitter, packet loss, and out-of-sequence in the Internet network have proved that the static JB technology can not play a good anti-jitter effect. Therefore, for the c...

Problems solved by technology

The end result is that when there is a network spike, the incorrect adjustment of the JB depth leads to continuous packet loss for a period of time, seriously affecting the voice quality of VOIP

[0026] The impact of network spikes on VOIP service quality cannot be ignored. If dynamic JB cannot effectively and correctly adapt to such network spikes, almost all data packets will be lost at the call receiving end for a period of time.

That is to say, if the depth of dynamic JB cannot adapt to the network spikes that appear at any time, it will not be able to provide voice services acceptable to network users for networks that may frequently experience network spikes
