Abstract

UMTS radio pristupna mreža (UMTS Terrestrial Radio Access Network - UTRAN) bazirana je na ATM i IP prijenosnim tehnologijama, te omogućava široki spektar usluga za mobilne korisnike kao što su video telefonija, internet pretraživanje velikim brzinama, mobilni TV, itd. Različite usluge zahtijevaju različitu brzine i kvalitetu prijenosa pa se stoga prijenosni sustav može opisati preko višeuslužnog modela s gubicima. Ovaj rad se fokusira na primjeni analitičkih metoda za dimenzioniranje IUB sučelja u UMTS mreži koje povezuje radio baznu postaju (NodeB) i radio mrežni kontroler (RNC). Cilj rada je pokazati kako zahtjevi za uspostavu podatkovnih poziva u UMTS mrežama pristižu prema Poissonovom procesu što je preduvjet za korištenje Kaufman-Robertsovog algoritma. U tu svrhu koristit će se mjerenja i podaci prikupljeni iz više komercijalnih UMTS mreža. U radu se analiziraju najvažnije komutacijske alternative u UTRAN mreži kao što su CBR VC, CBR AAL2, Dinamički IP, Statički IP itd. Rad, pored navedenog, sadržava pregled UMTS mreže i protokola u radio pristupnoj mreži, opis UMTS prometnog modela i općenit proces dimenzioniranja.

Abstract (english)

UMTS radio access network (UMTS Terrestrial Radio Access Network - UTRAN) is based on ATM and IP transport technologies, enabling wide portfolio of services for mobile users like video-telephony, high-speed internet access, mobile TV, etc. Different services have different bandwidth requirements and grade of service, so the transport system can be described with multi-rate Erlang loss system. This work is focusing of application of analytical methods for capacity dimensioning of IUB interface that connects radio base station (NodeB) and radio network controller (RNC) in the UMTS radio access network. The main goal is to prove that arrival process for packet data calls can be described by Poisson process that is a prerequisite for using analytical tools like Kaufman-Roberts algorithm. For that purpose, real measurement data from commercial UMTS networks will be used. The work will cover and describe most important switching alternatives in UTRAN network including CBR VC, CBR AAL2, IP Dynamic, IP static, with simple examples of IUB interface dimensioning. In addition, content of this work includes overview of UMTS network with protocols in radio access network, generic dimensioning process and description of UMTS traffic profile.
