Abstract

Evolucijom 3G mobilnog širokopojasnog prometa koji nudi visoke brzine prijenosa podataka ukazala se potreba za razvojem mehanizama koji jamče učinkovito rukovanje radio resursima. Usko grlo 3G podatkovne mreže može se nalaziti u različitim dijelovima mreže, ovisno o infrastrukturi (npr. u radijskom ili jezgrenom dijelu). Operateri odlučuju na koji način se nositi s problemom zagušenja, bilo širenjem mreže, povećavajući CAPEX ili pronalaženjem i korištenjem načina za kontrolu podataka. Fokus ovog rada je istraživanje uloge i važnosti planiranja i upravljanja kvalitetom usluge u UMTS i HSPA mreži. Obzirom na ograničenje mrežnih radio resursa, QoS mehanizmima mreža ima sposobnost diferencijacije korisnika i naknadne raspodjele resursa na način da svi korisnici u sustavu dobiju traženi QoS u smislu brzine prijenosa i kašnjenja u skladu s dozvoljenim QoS profilom i kapacitivnim mogućnostima mreže. U radu se analiziraju metode QoS diferencijacije te upravljanje prioritetima u mobilnoj 3G mreži kao i njihov utjecaj na postojeću jezgrenu mrežu.

Abstract (english)

3G mobile broadband evolution offers high speed data transfer. A need to develop QoS mechanisms to ensure effective handling of radio resources occures. Bottleneck for 3G data network may be located in different parts of the network, depending on the infrastructure (eg the radio access part or core network part). Operators will decide how to deal with network congestion problem: expanding the network, increasing CAPEX or finding and using ways to control traffic. Due to radio resources limitation using QoS mechanisms network has the ability of user differentiation and the subsequent resource allocation in a way that all users in the system receive the required QoS in terms of transmission speed and delay in accordance with the allowed QoS profiles and capacitive network capabilities. This work investigates the role and importance of some key aspects of QoS planning ,QoS management, QoS differentiation and priority management for UMTS and HSPA network.
