Summary

ITU-T Recommendation E.802 provides a framework and methodologies for the identification of QoS criteria relevant to users and guidelines for conversion of these criteria into QoS parameters that can be used to evaluate the QoS of telecommunication services.

Guidelines are also given to obtain user's QoS requirements and to prioritize the criteria or parameters. All these may be applied to services supported by the terrestrial and wireless legacy networks as well as services supported by the emerging IP network.
