A method for estimating a quality of experience of a user receiving an information content stream distributed through a telecommunications network, comprising: - generating a user behavior model, depicting a behavior of the user in the interaction with the telecommunications network, by considering a corresponding set of user behavior dimensions, each user behavior dimension being a descriptor describing a corresponding feature of said behavior; - implementing said user behavior model by selecting combinations of user behavior dimensions of said set of user behavior dimensions; - providing monitoring units adapted to perform measures on specific parameters of the information content stream and to emulate the behavior of the user in the interaction with the telecommunications network; - setting the monitoring units, said setting the monitoring units comprising setting the number, type and/or location of the monitoring units based on said selected combinations of user behavior dimensions; - assigning to the monitoring units test cycles comprising interaction operations with the telecommunications network to be carried out by said monitoring units; - generating for each monitoring unit a corresponding script to be executed by said monitoring unit based on said selected combinations of dimensions and said assigned test cycles, said script comprising indications about the interaction operations of said assigned test cycles; - at the monitoring units, carrying out said test cycles by running the generated scripts, and carrying out measurements on parameters of the information content stream received in response to said test cycles to obtain acquired measured values, and - calculating quality of experience indicators by processing said acquired measured values, wherein: each user behavior dimension of said set of user behavior dimensions may assume a plurality of different user behavior dimension values, said implementing the user behavior comprising generating at least one first table comprising a plurality of first elements, each first element quantifying the relationship among dimension values of the dimensions of the set of dimensions. - generating a user behavior model, depicting a behavior of the user in the interaction with the telecommunications network, by considering a corresponding set of user behavior dimensions, each user behavior dimension being a descriptor describing a corresponding feature of said behavior; - implementing said user behavior model by selecting combinations of user behavior dimensions of said set of user behavior dimensions; - providing monitoring units adapted to perform measures on specific parameters of the information content stream and to emulate the behavior of the user in the interaction with the telecommunications network; - setting the monitoring units, said setting the monitoring units comprising setting the number, type and/or location of the monitoring units based on said selected combinations of user behavior dimensions; - assigning to the monitoring units test cycles comprising interaction operations with the telecommunications network to be carried out by said monitoring units; - generating for each monitoring unit a corresponding script to be executed by said monitoring unit based on said selected combinations of dimensions and said assigned test cycles, said script comprising indications about the interaction operations of said assigned test cycles; - at the monitoring units, carrying out said test cycles by running the generated scripts, and carrying out measurements on parameters of the information content stream received in response to said test cycles to obtain acquired measured values, and - calculating quality of experience indicators by processing said acquired measured values, wherein: each user behavior dimension of said set of user behavior dimensions may assume a plurality of different user behavior dimension values, said implementing the user behavior comprising generating at least one first table comprising a plurality of first elements, each first element quantifying the relationship among dimension values of the dimensions of the set of dimensions.
