Individual Quality of Service Concept in Next Generations Telecommunications Networks
After the review of published articles and with the help of measurement data this paper shows that mobile communication conditions are not equal for different users. For some of them it can be even bad. From the point of view of individual user communication conditions can be modelled with the help of non-stationary random processes. After proof that mobile telecommunication conditions can not be equal it is proposed to develop individual quality evaluation modules and their deployment system. Relations between SP and the end-user should be based on SLA. This regulation includes compensations for unachieved level of quality. Currently conception of de facto perceived quality level is only hypothesis. This conception is far from deployment. This work tries to form technological methods for evaluation of de facto perceived quality. Presented work discusses means for iQoS modules construction and their placement in network infrastructure. Methods of initial information for quality evaluation gathering are reviewed, too. This paper forms a list of problems which should be solved in order to deploy iQoS concept. Also there are given some solution methods of these problems. Ill. 7, bibl. 11 (in English, summaries in Lithuanian, English, Russian).
