Abstract

The invention provides a method, a device and a system for improving data transmission quality. The method comprises the following steps: the redundancy processing for a transmission message is carried out according to the classification of transmission data. The redundancy processing for the transmission message is concretely carried out in such a way that the transmission message carries the content of another transmission message before the transmission message. In the invention, the redundancy processing for the transmission message is carried out by classifying transmission data according to the classification state of the transmission data, thus, under the condition that data packets are lost, the lost data packets can be recombined and recovered; and under the condition that the data packet losing rate is determined, the transmission quality and the transmission efficiency of the data can be further ensured.

Description

technical field

[0001] The invention relates to the communication field, in particular to a method, device and system for improving data transmission quality. Background technique

[0002] The packet-switching network based on the Internet Protocol (IP, Internet Protocol) has developed vigorously in recent decades and has become a communication network covering the whole world. IP network has advantages such as low cost. With the development of communication, more and more traditional telecommunication services including voice services are carried by IP networks.

[0003] IP-based voice (VoIP, Voice over IP) is a service that requires high real-time performance, and generally uses a real-time transport protocol (RTP, real time protocol) as a bearer protocol. RTP is a transport protocol for multimedia data streams on IP networks. RTP is defined to work in one-to-one or one-to-many transmission situations, and its purpose is to provide time information and media stream sync...
