Anotace: This paper deals with mathematical methods of dimensioning HSS (Home Subscriber Server) in IMS. Today, there are still more and more requirements on QoS (Quality of Service). Optimal QoS has to be reached by optimization of used components in network architecture. Models that are used – Erlang C formula and Markov chains M/M/1/K & M//M/m/K are simulated in MATLAB. Then outputs are displayed in graphs.
