[0047] This embodiment takes a voice communication system as an example for description. This embodiment manages the transmission of voice packets (a specific type of data packet), and specifically performs transmission control based on the survival time of each voice packet to realize voice calls. Quality control to improve the quality of voice transmission.

[0048] In practical applications, voice calls are one of the most important applications in the current communication network. The quality of voice calls is directly related to the user’s experience on the network. However, a key problem in current voice calls is caused by too many users in the network. Whether it can provide users with a relatively satisfactory voice quality when congestion or when the signal-to-noise ratio decreases and the code rate drops and causes congestion. With the advancement of communication methods, the encoding rate of voice continues to increase. For example, the voice code rate has changed fr...

Abstract

The invention provides a data packet transmission method and device, and a communication system. The method comprises the steps of storing data packets in a transmission cache area; obtaining time to live of the data packets in the transmission cache area; processing the data packets in the transmission cache area according to the time to live of the data packets; and transmitting the processed data packets in the transmission cache area. Through application of the method, the device and the system, a transmission node is arranged in the transmission cache area; when a network state is bad and congestion occurs, the data packets needing to be transmitted are cached; the time to live of the data packets is obtained; the cached data packets are processed according to the time to live of the data packets, for example, the data packets with excessively long time to live are discarded; in this way, the invalid data packets are not transmitted in follow-transmission; the network load is reduced; and the problem that the invalid data packets exist in the existing data packet transmission method is solved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a data packet transmission method and device, and a communication system. Background technique [0002] In a communication system, data transmitted by transmission nodes such as base stations are transmitted in the form of data packets. In the prior art, the transmission nodes sequentially transmit data packets to the target device according to the generation time of the data packets. When the network is unstable or insufficient resources, Some data packets will be directly discarded by the target device when they are transmitted to the target device due to the long survival time, which results in poor timeliness. Such data packets are invalid and not only make no contribution to the communication quality, but also occupy transmission resources. The network status is worse. [0003] Therefore, how to provide a data packet transmission method capable of managing data pack...
