Video service is the main service in 4G network

so ensuring user’s video watching experience is one of the key ways to enhance the market competitiveness of operators. Starting from the detailed procedure of video playing and combining user’s CDR in signaling monitor system

two key video service indicator algorithms

initial play delay and video fluency

are proposed

and the problem that traditional video indicators can not reflect the user’s experience is solved. All 4G user’s video watching experience can be evaluated with the algorithms

and network optimization in service aspect can be carried out with multiinterface data sources.
