Description

Apparatus and method for analyzing data quality of service {APPARATUS AND METHOD FOR PROVIDING QUALITY ANALYSIS OF DATA SERVICE}

The present invention relates to data service quality analysis technology, and more particularly, to a data service quality analysis apparatus and method suitable for analyzing data service quality experienced by a customer from a mobile carrier perspective.

In order to actually measure mobile network performance, the operator must carry the equipment necessary for the measurement and move to the field to collect data. This is a time and space constraint for network managers to collect performance on-demand at desired moments and places.

In addition, since the user input environment required for the measurement is extremely limited, there is a limit in analyzing statistically significant values such as the performance of the entire network.

In the future, mobile Internet applications may evolve to make the best use of the intelligence of mobile operators, and for this purpose, scales that can effectively measure / collect / analyze behavioral characteristics of the entire network. It is necessary to introduce a scalable network system.
