为了能够从系统侧更为准确地评价移动流媒体业务的用户感知，通过对基于HTTP live Streaming（HLS）的移动流媒体技术原理的研究，尤其是对索引文件信息的研究，采用分层思想将移动流媒体业务用户感知评价分为用户感知、业务质量和KPI指标三层，提出了一套移动流媒体业务的用户感知评价指标体系，并给出了基于索引文件信息的实现方法，说明了具体的指标定义和相应的统计点，该方法的提出有效解决了当前对移动流媒体的质量评价不能体现实际用户感知的问题。

In order to evaluate the user perception of mobile streaming media services from the system side more accurately, based on the research on HLS mobile streaming media technology principle, especial y the study on the index file information, using hier-archical thinking, the evaluation of mobile streaming media service user perception is divided into 3 layers, they are user per-ception, service quality and KPI. It proposes a set of mobile streaming media service user perception evaluation index system, and it gives the realization method of index file information based on the index, the definition of a specific and corresponding statistics. The method can solve the problem that the quality evaluation is not reflects the actual user perception.
