Embodiment approach

[0018] 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.

[0019] 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.

[0020] 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 the understanding of the pre...

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 ...
