Abstract

U sklopu ovog rada analizirane su performance trenutno najzastupljenije mobilne mreže (4G) na primjeru događaja koji okupljaju veliki broj korisnika. Predstavljena je arhitektura 4G mreže koja je u odnosu na prethodno korištene tehnologije, korisnicima omogućila povećani kapacitet, visoke prijenosne brzine te veći broj istovremeno posluženih uređaja.
Sukladno naglo rastućoj potrebi za kvalitetnim povezivanjem velikog broja uređaja, mrežni operatori suočeni se s velikim izazovima. Analizirani su različiti pristupi koje oni primjenjuju u mreži (makro i male ćelije) te su prikazani njihovi utjecaji na iskustvenu kvalitetu korisnika. Napravljena je detaljna analiza podataka prikupljenih u komercijalnoj pokretnoj mreži za dva mrežna operatora na području grada Zagreba. Cilj rada je utvrditi međuovisnost korištene tehnologije, parametara koji utječu na performance sustava i korisničkog iskustva.

Abstract (english)

In the scope of this thesis, the performance of the currently most represented mobile network (4G) was analyzed in the context of events characterized by a large number of end users simultaneously present in a given geographic region. A 4G network was presented. Comparing to previously used technologies, it is a network that provided users with increased capacity, high transmission speeds and larger number of simultaneously served devices.
In line with the rapidly growing need for connecting a large number of devices, network operators are facing major challenges. The different approaches they apply in the network (macro and small cells) have been analyzed and their effects on the Quality of Experience of end users have been discussed. A detailed analysis of data collected in the commercial mobile network has been made for two network operators in the Zagreb. The aim of this thesis is to determine the relationship between used technologies, parameters that affect system performance, and user experience.
