Abstract
Mobilno brezžično omrežje pete generacije je za razliko od prejšnjih generacij možno uvesti v samostojnem ali nesamostojnem načinu. Ob začetni uvedbi 5G se večina operaterjev odloča za nesamostojni način 5G v dvojni povezljivosti z obstoječim omrežjem 4G. V tej nalogi so na začetku predstavljeni razvoj omrežja 5G in razlogi za standardizacijo nesamostojnega načina 5G. V nadaljevanju je predstavljena arhitektura omrežja 4G, ki je osnova za delovanje nesamostojnega načina 5G. Predstavljeni sta tudi samostojna in nesamostojna arhitektura 5G. Pri nesamostojni arhitekturi je podrobneje predstavljena najpogosteje uporabljena arhitekturna izbira 3 in njene podizbire, ki jih je možno nastavljati prek različnih nastavitev podatkovnega radijskega nosilnika. Predstavljeni so tudi praktični vidiki uvajanja različnih arhitekturnih izbir. V praktičnem delu naloge sta najprej predstavljena testno okolje in postopek vzpostavitve dvojne povezljivosti, nato pa različne nastavitve in rezultati testiranj prikazovanja statusne ikone 5G na uporabniških napravah. Na koncu praktičnega dela so predstavljeni testne metode in rezultati testiranj različnih vrst podatkovnih radijskih nosilnikov nesamostojnega 5G.

Title:Non-standalone operating mode of fifth generation wireless mobile network
Abstract:
Unlike previous generations, the fifth generation mobile wireless network can be deployed in standalone or non-standalone mode. At the initial deployment of 5G, most operators are choosing a non-standalone mode of 5G with dual connectivity to the existing 4G network. This thesis initially presents the development of the 5G network and the reasons for the standardization of the 5G in non-standalone mode. This is followed by the presentation of 4G network architecture, which is the basis for the operation of the 5G in non-standalone mode. Presented are also standalone and non-standalone 5G architectures. In the case of non-standalone architecture, the most frequently used architectural option 3 and its sub-options, which can be set via various settings of the data radio bearer, are presented in more detail. Practical aspects of deploying different architectural options are also presented. In the practical part of the thesis, the test environment and the process of establishing dual connectivity are presented first, followed by various settings and test results of displaying the 5G status icon on user devices. At the end of the practical part, test methods and results of different types of non-standalone 5G radio data bearers are presented.

Keywords:fifth generation of mobile wireless network (5G), non-standalone 5G (NSA 5G), dual connectivity of the new radio in the evolved universal terrestrial radio access (EN-DC), architectural option 3, data radio bearer (DRB), status indicator 5G
