Traffic Load Analysis of the S-CSCF Component in IMS

U ovom radu opisane su osnove sustava IMS s posebnim naglaskom na komponentu S-CSCF. Sadrži kratak uvod u LTE, s obzirom na to da je IMS samo dio sustava LTE. Zatim slijedi opis sustava IMS skupa s njegovim komponentama, referentnim točkama, IMS registracijom i identifikacijom. Pošto je cilj ovoga rada analiza prometnih opterećenja S-CSCF komponente, S-CSCF komponenta i njena komunikacija s ostalim komponentama opisana je u posebnom poglavlju. Prije rezultata testiranja, prikazanih u numeričkom i grafičkom obliku u zadnjem poglavlju, dan je kratak uvod u Poissonovu distribuciju.In this paper, the basic of the IP Multimedia Subsystem with the special emphasis on the S-CSCF component were described. It brings a short introduction to the LTE, as the IMS is part of the LTE system, following with description of the IMS, its entities, reference points, IMS registration and IMS identification. S-CSCF and its communication with the other entities are described in the separate section, as the goal of this master thesis is to analyze traffic on the S-CSCF during the registration procedure. Before the testing results in the last section, presented in both numerical and graphical form, introduction into the Poisson traffic distribution model is given
