Sistem za usmerjanje gostujočih naročnikov

GOJGIČ, JERNEJ (author), Burnik, Urban (mentor)

V diplomski nalogi je predstavljeno delovanje usmerjevalnega sistema za gostujoče uporabnike. Najprej so predstavljeni splošni načini usmerjanja, kasneje pa preidemo na izvedbo, ki jo uporablja podjetje Tušmobil. V prvem delu spoznamo pojme in načine splošnega usmerjanja gostujočih uporabnikov. Tu sta v ospredju dva načina. Usmerjanje s SIM (ang. Subscriber Identity Module) se uporablja v manjšem obsegu, usmerjanje na mrežnem nivoju pa je kasneje, v osrednjem delu, opisano podrobneje. Tu imamo opisane tudi splošne principe in načine kako se terminal povezuje na omrežje in na kakšen način se testira kakovost storitev pri gostujočem operaterju. Zahtevnejši in bolj natančen od obeh je usmerjanje na mrežnem nivoju, zato je tekom osrednjega dela predstavljeno delovanje le-tega. V tem delu je opisan tudi ASoR (ang. Ant-Steering of Roamers) sistem, ki ni potrjen sistem za uporabo s strani GSMA (Groupe Speciale Mobile Association). Podrobneje je predstavljeno njegovo delovanje in detekcija takšnega sistema. Zadnji del opisuje izvedbo usmerjevalnega sistema na podjetju Tušmobil. Predstavljeno je delovanje, implementacija in logika delovanja sistema. Zraven pa so opisana in analizirana sporočila na MAP (Mobile Aplication Part) in SCCP (ang. Signalling Connection Control Part) nivoju, s katerimi sistem komunicira z ostalimi elementi v omrežju.

Abstract

The main theme of thesis is a presentation how system, steering of roamers, works. At first we get an overview in general and later on we go to the actual system which is implemented in Tušmobil Company. First part of thesis presents the concepts of general steering of roamers. Here we have two systems in overview. SIM (Subscriber Identity Module) based steering is used less frequently than network based steering, which is later on described in detail. General principles and means of connecting terminal to the network are also described in this section. Network based steering is far more superior and precise than SIM based steering, that is why, in mid-section, we focus on it even more. Through mid-section we also describe anti-Steering of Roamers and ways to detect it. By standards of GSMA (Groupe Speciale Mobile Association) it is not legal to own ASoR (Anti-Steering of Roaming) system. In last section there is an introduction and description to Tušmobil SoR system. Functionality, implementation and logic are described in detail. Passing last section reader also gets a clear overview how SoR system is communicating with other elements in network, hence the described and analyzed MAP (Mobile Application Part) and SCCP (Signaling Connection Control Part) protocols.
