Abstract: The main current concepts in overall Quality of Service (QoS) considerations in telecommunication systems, in documents of the leading standardization organizations, are found and put together. At least fifteen Open Issues for further study are formulated. Proposed are: Work Definitions of Communication and Telecommunication; A Reference Model of a Telecommunication System; Definitions of Overall Telecommunication Network and System Performance; Two Telecommunication System States’ modelling approaches are described; Parameters’ Classification Based on Their Values' Establishing Method is proposed, for the needs of design models; The necessity of Causal Classification of Values in Telecommunication Systems’ Models is argued; The necessity of Overall Telecommunication System’s Parameters’ Notation System is argued and a set of requirements is listed. An initial step of such notation system, proposed and used by authors is described.

Keywords: Telecommunication Systems, Telecommunication Network, Overall Quality of Service, Multi-Conceptual? Models, Models Scalability

ACM Classification Keywords: C.4 Performance of Systems, H.1.2 User/Machine Systems, I.6 Simulation and Modelling, I.6.0 General, H.1.2 User/Machine Systems, K.6 Management of Computing and Information Systems, K.6.0 Genera.
