3G (The Third Generation Telecommunication)-based method and equipment for guaranteeing service quality in real-time transmission service

Abstract

The invention discloses a 3G (The Third Generation Telecommunication)-based method and equipment for guaranteeing service quality in real-time transmission service. The method comprises the following steps: after an input port receives a message, carrying out service quality processing and merging into a queue; and before a media stream message is transmitted, according to a timestamp, judging whether the buffer time of the media stream message in a transmit queue is over a preset time threshold or not, if so, discarding media stream message, otherwise, transmitting the media stream message out through the destination port. The invention also discloses the 3G-based equipment for guaranteeing the service quality in real-time transmission service. The 3G-based method and the equipment for guaranteeing the service quality in the real-time transmission service can fully utilize network bandwidth to transmit the effective media stream message when the network bandwidth is fluctuated, and the condition that invalid media stream message is transmitted can be avoided.

Description

technical field [0001] The present invention relates to a Quality of Service (QoS for short) congestion management technology, in particular to a congestion management technology for real-time transmission of media stream services in network communication equipment. Background technique [0002] With the development of 3G (third generation mobile communication) wireless network technology and digital media stream compression technology, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) and WCDMA ( Wideband Code Division Multiple Access (CDMA) and other wireless networks to transmit media streams have become a very convenient industry application. The 3G network was born out of the 2G network with voice as the main business, and is not designed for the transmission of large-flow data; comprehensively considering the construction and operation costs and network carrying capacity, in an ideal state, the transmission bandwidth usually allocated by the operator t...

AI Technical Summary

Problems solved by technology

For real-time media stream transmission services under certain circumstances, due to the instability of the egress line bandwidth, when congestion occurs, only a small amount of media stream packets are buffered in the queue, and the newly arrived media stream is discarded. Similarly, the media stream packets in the queue may still be discarded at the destination due to the long buffer time.
