Abstract

U ovom radu obrađen je čvor vMTAS, dio vIMS mreže koji je ključan u postizanju konvergencije fiksne i mobilne mreže. Računarstvo u oblaku te platformska virtualizacija tehnologije su koje omogućuju prelazak iz IMS mreže u vIMS. U ovom primjeru korištena je programska podrška Openstack u kombinaciji sa alatom Fuel za postavljanje i održavanje virtualne mreže.
Čvor MTAS je IMS aplikacijski server tvrtke Ericsson, te ima središnju ulogu u realizaciji usluga i komunikaciji. U virtualnom okruženju MTAS ne gubi svoje mogućnosti, naprosto je izveden isključivo softverski.
Analiziran je slučaj korištenja usluge Flexible Communication Distribution koja preusmjerava poziv nakon određenog vremena ne javljanja. Paketski promet tijekom poziva uhvaćen je pomoću programskog alat Wireshark. Sakupljena razmjena signalizacijskih poruka prikazuje ulogu čvora MTAS unutar IMS mreže. Alat Wireshark koji također nudi mogućnost crtanja sekvencijskog dijagrama koji jasno pokazuje sav mrežni promet tijekom usluge relevantan za ovaj rad.

Abstract (english)

This thesis examines the vMTAS node as a part of the vIMS network and a key component in fixed-mobile convergence. Cloud computing and platform virtualization provide grounds for the IMS network to go virtual. This example uses Openstack software as well as Fuel to deploy and maintain the virtual network.
The MTAS node, an Ericsson product, is an IMS application server responsible for handling services and communication. When virtualized, the MTAS node retains its functionalities, while being deployed purely as software.
Flexible Communication Distribution, a service which redirects a call if it is not being answered, was used for analysis. Network protocol analyzer software Wireshark was used to capture packet based traffic during the call. The gathered signaling exchange provides insight into the role of the MTAS node within the IMS network. Wireshark has an option of generating a sequence diagram which clearly lays out all the network traffic relevant to this thesis.
