Embodiment Construction

[0024] The core idea of ​​the present invention is: for the P2P streaming media service carried in the mobile network environment, due to the time-varying nature of the environment quality and the mobility of nodes, the uncertainty of the executed policy information is caused. The invention adjusts the execution strategy adaptively through the dynamic measurement and real-time evaluation of the network quality and user service quality information, so as to provide users with better QoE guarantee.

[0025] The applicable network environment of the present invention is any wireless mobile network capable of carrying P2P streaming media services, such as WLAN, traditional cellular network (3G / LTE), and the like.

[0026] The implementation of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to prevent confusion to the understand...

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 ...
