User-oriented overall traffic, and time efficiency indicators in telecommunications

One of the problems of user experience prognostication in telecommunication services is the selection of Quality of Service (QoS) indicators, more reflecting users' experience, not the network providers' one. In this paper, we propose definitions and analytical expressions of four new overall network QoS time and traffic efficiency indicators, compared analytically and numerically. Some of them are mentioned in official documents, without any formal definition. They are more user-oriented indicators, compounding explicitly repeated attempts, effective duration of communication and total A-terminal occupation time.
