Abstract

The present invention relates to the network technology field. Disclosed are a method, an apparatus and a system for bandwidth estimation, which can obtain a more accurate bandwidth estimation value and solves a problem of low bandwidth estimation accuracy in prior art. Specific implementation of the present invention comprises: obtaining a radio bearer corresponding to a service to be measured, sending request information to a base station for requesting to obtain IP throughput of downlink scheduling of the radio bearer, and thus calculating a bandwidth of the radio bearer based on the IP throughput of downlink scheduling of the radio bearer. A technical scheme in the present invention is mainly applied in a bandwidth estimation process for a radio bearer.

Description

Technical field [0001] The present invention relates to the field of network technology, and in particular to a method, device and system for bandwidth estimation. Background technique [0002] At present, video services are widely used. Due to the large amount of data in video services, it has become an indisputable fact that video services trigger mobile digital torrents. The existing technology uses video optimization technology to deal with the threats brought by this digital torrent. Specifically, the video optimization technology mainly uses video caching, video transcoding, and dynamic network bandwidth adaptation. Among them, the dynamic network adaptation technology obtains the available video transmission bandwidth information by detecting or estimating the video transmission bandwidth. Supports dynamic selection of the video file bit rate adapted to the transmission bandwidth, so that when the network is congested, it can send users a low bit rate and smooth video, and...
