The user's loyalty is a key component to be considered by the mobile telecommunication operator into a highly competitive environment with a continuous growth of mobile internet services. For this reason, we propose a methodology to support the network performance decision to provide mobile internet services based in the users perception. The correlation between the Quality of Service parameters and the Quality of Experience is the base of this methodology; we use two different neural network models to obtain the final correlation model. The model is proved gathering information of five different cells using a 3G modem and a 3G mobile phone (Android OS). In this work we are validating the model obtained only with gathering network performance parameters.
