This next-generation network operation and management shall be based on the usage of Big Data Analytics techniques to monitor the end-user quality of experience through direct measures of the network. This paper describes the Astellia approach towards this network revolution and presents some results on the performance of quality estimation techniques in current cellular networks. Thanks to the use of this approach, operators may fill the gap of knowledge between network key performance indicators and user experience. This way, they can operate in a proactive manner and have actual measurements of the users' experience, which leads to a fairer judgement of the users' complaints.The authors would like to thank the funding received from the Ministerio de Industria, Energia y Turismo TSI-100102-2013-106 funds.Monserrat Del Río, JF.; Alepuz Benaches, I.; Cabrejas Peñuelas, J.; Osa Ginés, V.; López Bayo, J.; García-Zarza, R.; Domenech-Benlloch, MJ....
