1. A method for determining, in a communication system, a Quality of Experience associated with a real-time communication session between user devices of the communication system, the method comprising:
starting the real-time communication session;
monitoring the real-time communication session and determining, during the real-time communication session, at least one quality indicator indicative of the Quality of Experience, and at least one first performance indicator indicative of a Quality of Service and at least one second performance indicator indicative of the Quality of Service;
based on a self-learning process to which the at least one quality indicator and the at least one first performance indicator are applied, determining and continuously updating a correlation function indicative of the correlation between the Quality of Experience and the Quality of Service in respect of the monitored real-time communication session;
determining a parameter of the Quality of Service depending on both the at least one first performance indicator and the at least one second performance indicator, and
applying said parameter to the correlation function to determine said Quality of Experience,
wherein said determining a correlation function includes determining a value of at least one coefficient of the correlation function based on a previous value of the coefficient of the correlation function, and
the at least one second performance indicator comprises jitter buffer size.
