Abstract

Ponuda naprednih telekomunikacijskih usluga glavni je motiv evolucije jezgre UMTS mreže prema konceptu mreže sljedeće generacije, pri čemu je sa stanovišta arhitekture, najvažnija promjena uvođenje višemedijskog IP podsustava, IMS. Usluge umrežene virtualne stvarnosti, koje omogućavaju distribuiranim korisnicima da sudjeluju u zajedničkim interaktivnim računalnim simulacijama stvarnih okruženja, se mogu smatrati primjerom naprednijih usluga koje će nuditi višemedijski IP podsustav.
Budući da su i specifikacije i sustavi za mreže sljedeće generacije u razvoju, za potrebe laboratorijskih istraživanja se koriste emulatori koji zamjenjuju skupe ili nedostupne sustave. U ovom radu je osmišljen i programski izveden emulator upravljanja sjednicom za usluge umrežene virtualne stvarnosti u UMTS-u. U emulator, koji se uklapa u arhitekturu i mehanizme IMS-a, su ugrađeni protokoli SIP i COPS, specificirani za uporabu u IMS-u. Na temelju njih je razvijena i programski izvedena signalizacija za upravljanje sjednicom prema specifikacijama udruge 3GPP, uz proširenja potrebna za podršku posebnih zahtjeva usluga umrežene virtualne stvarnosti.

Abstract (english)

Offering advanced telecommunication services is the main goal of the evolution of UMTS network core toward the next generation network concept. From the architectural viewpoint, the most important improvement is the introduction of the IP Multimedia Subsystem, IMS. Networked virtual reality services, which enable distributed users to take part in shared, interactive computer simulations of real environments, can be considered representatives of advanced services to be offered by the IMS.
Since both the specifications and the systems for next generation networks are still being developed, using emulators for laboratory research can replace expensive or unavailable systems. This master thesis describes the design and implementation of a session management emulator for networked virtual reality services in UMTS. SIP and COPS protocols, specified to be used in the IMS, were integrated in the emulator, which is in line with IMS mechanisms and architecture. Based on these protocols, signaling mechanisms were designed and implemented for session management as specified by 3GPP. Extensions needed for the support of specific virtual reality services requirements were added.
