Theoretical Approach to Optimization of Home Subscriber Server in IP Multimedia Subsystem

Our paper deals with structure of Home Subscriber Server in IP Multimedia Subsystem and mathematical models for optimizing this database. The aim of our work is choose and verify proper models for dimensioning of traffic in the HSS. In this paper we describe the Markov M/M/1/K and M/M/m/K models and Erlang C formula. Simulations are graphically interpreted in MATLAB and results are discussed.
