Methodological support for communication networks and services quality management

The paper is devoted to the analysis of the known methodological support for quality assessment and control of communication services. The known approaches to quality assessment of communication services have mainly been developed in relation to the situation, characterized by the fact that each management system actually relied on its own, dedicated communication system. In this case, most of the results apply to analogue communication systems with predominantly assigned channels (paths) to certain information directions, which together reflect the structure of the control system. The synthesis of communication systems is based on the requirements of the respective control system. As a result of the analysis, the limitations of the known methodological support in the field of assessment and control of the communication services quality were revealed. In order to eliminate the identified limitations of the known methodological support in the field of assessment and control of the quality of communication services, the author has developed: analytical and simulation model of an information and telecommunication system with the required level of reliability of its elements; method for determining the parameters of the development directions of telecom operators’ networks; method for assessing the probabilistic-temporal indicators of the technical resource of the fragments of the information and telecommunication system, generating communication services of a certain type.
