Abstract

U radu su obrađeni parametri kvalitete prijenosa multimedijskih usluga u UMTS mrežama. Obrađena je tehnologija višestrukog pristupa u UMTS sustavima, te su navedene prednosti signala sa proširenim spektrom kao što su otpornost na interferenciju, povećanje ukupnog kapaciteta mobilnah sustava dijeljenjem istog frekvencijskog spektra između više korisnika te mala mogućnost presretanja širokopojasnog signala male gustoće snage. Navedene se osnovne karakteristike i tehnička obilježja WCDMA sustava. U radu je dan pregled paketnog prijenosa širokopojasnog CDMA radio signala sa evolucijom 3GPP arhitekture. Detaljno je obrađena mogućnost integracije radiokomunikacijske lokalne mreže kao pristupne mreže za prijenos multimedijskih sadržaja. Kroz rad je dan pregled parametara koji utječu na kvalitetu pružene usluge. Kako na kvalitetu multimedijskih usluga utječu i korištene kodne sheme one su detaljno obrađene u posebnom poglavlju. U zadnjem dijelu rada dan je pregled parametara kvalitete koji utječu na prijenos multimedijskih usluga u UMTS mobilnam mrežama te njihove preporučene vrijednosti po klasama UMTS usluga.

Abstract (english)

This paper focuses on quality parameters for transmission of multimedia services in UMTS mobile networks. Multiple access technology used in UMTS systems is detailed described. All of the key aspects of spread signals are covered like interference resistance, total capacity increase due to the reusage of the same bandwith between multiple users and low probability of interception of spread spectrum signal with low power density. Basic characteristis and technical key implementation elements of WCDMA systems are stated. In the paper, treatment of packet data transmission of wideband CDMA radio signal is explained within 3GPP architecture evolution. The possiblity of integration of WLAN access networks with UMTS system is elaborated in details. Through the paper all parameters related to service quality are given. Due to the fact that quality of multimedia services also depends on used coding shemes, they are detailed explained in separate part of the paper. In the last part of the paper, the quality parameters for transmission of multimedia services in UMTS mobile network are listed with their proposed values for UMTS classes of services.
