Method for guaranteeing mobile peer-to-peer network stream media service experience quality

Abstract

The invention discloses a method for guaranteeing mobile peer-to-peer network stream media service experience quality, comprising a strategy action and a strategy variable, wherein the strategy action is used for describing an execution action of mobile P2P stream media QoE strategy management process, and the strategy is used for describing a reference variable in MP2P stream media QoE strategy management process; the strategy action comprises a buffer management strategy action, a node selection strategy action and a data invoke strategy action, and the strategy variable comprises a global strategy variable, a buffer management strategy variable, a node selection strategy variable and a data invoke strategy variable. The method is applied to a P2P stream media service in a mobile network, which can select and update QoE management strategy in real time according to dynamic change of mobile network environment, and effectively cope the influence to the stream media transmission quality from wireless channel quality dynamic change and node mobility so as to provide good QoE guarantee through self-adaptive QoE strategy management.

Description

technical field [0001] The invention relates to the technical field of peer-to-peer network (P2P) streaming media, in particular to a method for ensuring quality of experience (QoE) of mobile P2P (MP2P) streaming media services in a mobile network environment. Background technique [0002] Streaming media is also called streaming media. This technology enables audio, video and other multimedia files to be played on the Internet in real time without downloading. It only needs to store the beginning part in the cache area, and then the user can play while downloading. , so that the waiting delay is greatly reduced. The rapid development of broadband network has promoted the wide application of live streaming system technology. P2P streaming media introduces P2P technology into streaming media transmission, which can make full use of terminal resources and reduce operating costs. It has been widely used in the Internet. However, because P2P streaming media services have high ...

AI Technical Summary

Problems solved by technology

However, the existing algorithm only improves the performance of one aspect of the system, and cannot guarantee the quality of streaming service and improve the utilization rate of the network. The node selection mechanism still needs further research and development to meet the requirements of large-scale distribution of streaming media in P2P systems.

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