Abstract: The present invention relates to a method for calculating user experience perception of the quality of monitored integrated telecommunications operator services. For this purpose, data from the monitoring of user services is used, along with questionnaires previously completed by a representative sample of users for subsequent combination by means of correlation algorithms, and after they have been put through automatic learning algorithms, obtaining a value for the quality of the experience, which implies an estimate of the quality of service perceived by the user of said service. Lastly, the network parameters that most affect the QoE as a function of the relevance thereof for predictions of quality are automatically identified in order to provide the values needed to attain a certain quality of experience as defined by the user.
