Video transmission method and system and base station

Abstract

The invention discloses a video transmission method and system and a base station, and aims to schedule air interface resources and / or adjust the scheduling priority of user equipment according to code rate information of video segments of a video source in order to balance the air interface resources of the user equipment and reduce the phenomenon of lagging. The method in the embodiment of the invention comprises the following steps that: the base station acquires code rate information of video segments of a video source; the base station schedules air interface resources and / or adjusts the scheduling priority of user equipment according to the code rate information; and the base station transmits the video source to the user equipment according to the scheduled air interface resources and / or the adjusted scheduling priority of the user equipment.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a video transmission method, base station and system. Background technique [0002] With the development and maturity of mobile network technology, various emerging mobile services are booming. Among various services on mobile networks today, video services occupy a large part of network traffic. Although the performance of the current mobile communication system has been greatly improved compared with the previous ones, with the continuous increase of video services and the continuous pursuit of higher-definition video in the market, the mobile communication system still faces the problem of insufficient air interface resources. To play video services with a large amount of data, the user equipment needs more air interface resources to support the playback of video services with a large amount of data. The playback of the video service causes a freeze phenomenon ...

Problems solved by technology

[0004] However, the existing scheduling algorithm ignores the characteristics of the video service itself, that is, the video service uses video segments as independent units to request transmission in the network, and the average bit rate within the video segment duration fluctuates significantly, and the longer the segment length Short, the greater the difference between peaks and troughs, that is, there are significant differences in the amount of data in different video segments

When there is a significant difference in the data volume of the video segments of the video service, more air interface resources are required for video segments with large data volumes, and according to the existing scheduling algorithm, the allocation of video segments with different data volumes The air interface resources are the same. Obviously, in the process of playing video segments with a large amount of data, the existing scheduling algorithm is not enough to support the playback of video segments with a large amount of data, which is often prone to freezes and affects the viewing experience.
