The invention provides a data analysis device, system and method. According to the data analysis device, on one hand, data of a certain network node of a mobile access network can be collected, then data analysis is carried out, configuration parameters of the network node are adjusted, targeted data analysis and parameter adjustment of the network node are achieved, and therefore the speed of data analysis and configuration parameter adjustment can be increased; and on the other hand, the modules of the data analysis device can run in parallel, so that the speed of data analysis and configuration parameter adjustment can be further improved.
