Embodiment Construction

[0019] The embodiment of the present invention provides a delay processing method and device for improving the call quality of VoIP service under different network conditions.

[0020] The basic principle of the delay debounce solution adopted in the embodiment of the present invention is: when the network jitter is severe, the delay is increased; when the network jitter is reduced, the delay is reduced. The embodiment of the present invention provides the delay adjustment speed according to different changes of network jitter, and achieves a lower actual packet loss rate and a better voice effect by distinguishing the rate of delay increase and delay decrease. When the delay needs to increase, adjust quickly to avoid excessive network packet loss. When the delay needs to decrease, the adjustment process should be slowed down as much as possible to avoid unnecessary packet loss caused by frequent adjustments and affect call continuity. .

[0021] In the embodiment of the pres...

Abstract

The invention discloses a method and a device for processing time delay to improve connection quality of a VoIP business under different network conditions. The method for processing the time delay comprises the following steps: determining a network jitter parameter for expressing a current network jitter condition; adjusting the time delay parameter of jitter buffer (Jitter Buffer) according to the current network jitter parameter; and carrying out time delay treatment on a data packet in the Jitter Buffer according to the adjusted time delay parameter of Jitter Buffer.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a delay processing method and device. Background technique [0002] IP-based voice transmission (Voice over Internet Protocol, VoIP) is a value-added service based on IP telephony, that is, the analog voice signal is transmitted in real time on the IP data network in the form of "data packets". With the wide application of VoIP technology, various gateway products are used more and more widely at home and abroad to realize the conversion of analog voice signals into voice packets, and fax the voice packets on the IP network. The voice packets are packaged according to the Real-time Transport Protocol (RTP) format, and the peer gateway converts the voice packets into analog sound signals and plays them out. This technology makes it possible to transmit voice through the IP network, forming a voice transmission mode different from the Public Switched Telephone Net...
