Model architecture for realizing streaming media experience quality strategy management of mobile peer-to-peer network

Abstract

The invention discloses a strategy management model architecture applied to streaming media service experience quality (QoE) of a peer-to-peer network (P2P) in a mobile network, which is capable of providing a well service QoE guarantee for a node in a dynamically changed mobile network environment and on the premise of satisfying user demands. The model architecture mainly consists of the following modules: a mobile P2P (MP2P) streaming media server used for user service request processing, user information obtaining and QoE management strategy execution; a QoE evaluation module used for the mobile network environment information obtaining and user QoE dynamic evaluation; and a strategy server used for dynamically selecting and updating the QoE management strategy information. The model architecture disclosed by the invention can be applied to the QoE strategy management of P2P streaming media service based on a mobile cellular communication system, can effectively reduce the influence of network dynamism and terminal isomerism to the service quality and achieves the purpose of guaranteeing the QoE performance of the mobile P2P streaming media service.

Description

technical field [0001] The present invention relates to a peer-to-peer network (P2P) streaming media technology field, in particular, it is a model framework for realizing mobile P2P (MP2P) streaming media service Quality of Experience (QoE) policy management in a mobile network environment. Background technique [0002] Streaming media, also known as streaming media, is a product of the development of network audio and video technology to a certain stage. It is a "soft technology" that solves the problem of network bandwidth during multimedia playback. Streaming media is to divide continuous video and audio information into compressed packets through a special compression method, and transmit them continuously and in real time from the audio and video server to the user terminal. A small piece of data of the file downloaded in advance is used as a buffer, and the playback process uses the data in this small piece of buffer for playback. While playing, the remainder of the ...

AI Technical Summary

Problems solved by technology

For P2P streaming media services, QoE problems are mainly manifested in long playback delay, unstable playback quality, and insufficient support for video-on-demand VCR operations (play, pause, random jump, etc.). It is difficult to directly apply the QoE management method proposed in the existing research to the P2P streaming media system.

However, there is no relevant research on applying policy management to P2P streaming media systems.
