Embodiment 1

[0024] figure 1 A flowchart of a method for network bandwidth adaptive QOS transmission according to an embodiment of the present invention. Described method comprises the following steps:

[0025] S101, preset and update the first network status information in real time; preset a time period, and preset at least two bit stream levels for each on-demand or live stream;

[0026] The first network state information is the network state information during the streaming media session, including the latest network bandwidth, the latest data packet loss rate, the latest round-trip delay, and the latest jitter variance value;

[0027] The specific code stream level and its corresponding code stream size can be configured through the encoder or transcoder. For easy understanding, for example, for the network environment of GPRS / EDGE, the following code stream levels can be configured 15K, 20K, 25K, 30K, 35K, 40K, 50K, 60K, 80K, 100K, for TD or other 3G network environments, the foll...

Embodiment 2

[0066] figure 2 It is a schematic structural diagram of a system for network bandwidth adaptive QOS transmission according to an embodiment of the present invention.

[0067] The system includes an initial module, a statistics module, a comparison module, and a judgment module;

[0068]The initial module is connected with the statistical module, the comparison module and the judgment module, and is used to preset and update the first network status information in real time; it is also used to preset the time period, and preset at least two code streams for each on-demand or live stream grade;

[0069] The first network state information is the network state information during the streaming media session, including the latest network bandwidth, the latest data packet loss rate, the latest round-trip delay, and the latest jitter variance value;

[0070] The specific stream level and its corresponding stream size can be configured through the encoder or transcoder. For ease o...

Abstract

The invention discloses a network bandwidth self-adaptive QOS (quality of service) transmission method and system and a terminal device. The network bandwidth self-adaptive QOS transmission method comprises the following steps of: presetting first network state information and a code stream grade in a streaming media session process; obtaining second network state information in real time by utilizing a network period feedback protocol; and comparing the second network state information with the first network state information to determine whether the current network is jammed, if so, down-regulating the code stream grade or sending speed, and if not, keeping or up-regulating the code stream grade or the speed to realize dynamic regulation to real-time communication flows of mobile streaming media. According to the network bandwidth self-adaptive QOS transmission method and system and the terminal device disclosed by the invention, the size of code stream and the sending speed of a streaming media business source can be automatically regulated according to fluctuation of mobile internet bandwidth through a large-scale data acquisition and model test to ensure the stability of real-time transmission of streaming media audio-video data in a mobile internet environment, therefore, different network conditions can be adapted, and user experience can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of mobile Internet, and in particular to a method, system and terminal equipment for adaptive QOS (Quality of Service, Quality of Service) transmission based on network bandwidth. Background technique [0002] At present, my country has become the fastest growing mobile phone user group with the largest number of users in the world. Under the active promotion of national policies, the application of streaming media technology will bring revolutionary changes to the network information exchange of the mobile Internet, and will have a profound impact on people's work and life. Although the development of 3G is surging, in fact, the upgrade from 2G to 3G is a long process. In the foreseeable few years, 3G will still be under construction, and a large number of users will still use 2G network services. However, under the original technical conditions, users of 2G networks cannot enjoy a good multimedia...
