随着移动互联网的发展和4G网络的成熟,移动视频业务已逐步成为主流业务,移动视频已成为互联网企业抢占的制高点,运营商在其中如何定位需要深入思考。本研究首先立足网络本身,在4G环境下研究视频感知监测、缓存、动态转码等一系列技术手段,建立视频质量优化与保障体系。在此基础上,探索构建3GPP标准的AAC(Application Access Control,应用接入控制)架构,结合PCC(Policy and Charging Control,策略及计费控制)功能,通过标准接口将网络QoS(Quality of Service,业务质量)能力向互联网公司开放,参与视频的业务调度过程,进而具备分享业务价值链的能力。

A research of mobile video optimization technique

With the rapid development of Mobile Internet and the mature of 4G networks ,mobile video service has gradually become the mainstream service.While mobile video has become the peak point which internet players race to control, for operators,how to take strategic position in this domain should be deeply considered.This research is based on the network itself primarily,researching a series of technical means such as video sensing monitoring,caching,dynamic transcoding,etc.in the 4G environment,then establishing video optimization and quality assurance system.On this basis,the study explore constructing AAC architecture complying with 3GPP standard,opening network Qos capability,combined with PCC function,to internet players via standard interfaces.Therefore operators participate in the process of video traffic scheduling,and thus foster the capability to share business value chain.
