Abstract
V diplomski nalogi je predstavljeno upravljanje naročnikov med gostovanjem v tujem mobilnem omrežju s tehničnega vidika in kakšni so razlogi za takšno početje. V nalogi sem opisal dve metodi, ki se ob tem uporabljata ter izvedbo v podjetju Si.mobil, kjer sem tudi zaposlen. V začetnem delu sem omenil, kateri so potrebni predpogoji za mobilno gostovanje in katere tipe gostovanj poznamo. V tem delu so predstavljeni komercialni in tehnični procesi, kot so Pogodba o gostovanju, popustih, medomrežna povezljivost, ponujene storitve med gostovanjem ter njihovo obračunavanje, torej postopki, ki so potrebni, preden sleherno mobilno omrežje ponudi gostovanje svojim naročnikom in omogoča gostovanje naročnikom partnerskega omrežja. V nadaljevanju pišem o osnovni strukturi mobilnega omrežja in njenim delovanjem. Poudarek je na signalizaciji, saj nam bo poznavanje le-te koristilo za razumevanje upravljanja gostovanja v tujini. Predstavljena je arhitektura signalizacijskega sistema SS7 in njen protokolni sklad ter SS7 protokoli, ki služijo za delovanje mobilnega omrežja, kot npr. MTP, SCCP in MAP. Osrednji del je namenjen podrobnejšemu opisu delovanja dveh tipov preusmerjanja, signalizacijsko osnovanega SoR ter načina z uporabo t. i. storitve po zraku OTA. Navajam katera GSMA priporočila moramo ob implementaciji določenega mehanizma upoštevati ter katere so prednosti in slabosti posameznega tipa preusmerjanja. V tem delu predstavim praktični primer komercialnih modelov, ki so ključni faktor pri odločanju in postavljanju strategije naših uporabnikov v gostovanju. V tretjem, zadnjem poglavju, je predstavljen praktičen primer realizacije upravljanja v podjetju Si.mobil. Namen tega je pokazati, kako spremljamo uspešnost preusmerjanja in kateri so ključni kazalci, ki jih moramo upoštevati, ter njihov pomen. Navajam tudi, kako se ti kazalci spreminjajo glede na naše nastavitve. V zaključku so predstavljeni rezultati preusmerjanja s komentarji.

Title:Managing steering of roaming
Abstract:
The thesis presents managing steering of roaming subscribers in foreign mobile networks from technical and commercial point of view. At first, we present two kinds of mechanisms which are used for steering purposes. Next we will get familiar with practical execution of steering of roaming in company Si.mobil. In the initial part we explain what the prerequisites for execution of steering of roaming are. These include the commercial and technical procedures, like Roaming agreement, Discount agreement, interconnection, roaming services and billing procedures, basically all the processes which are needed for offering the roaming service to own customers and enable roaming of customers of our roaming partner. Next section is dedicated to basics of mobile networks and its functionalities. Main focus in this section is on signalization, since its understanding is needed for steering of roaming. Within signalization we illustrated the architecture of signaling system number 7, its protocol stack and protocols, which are the support for mobility in mobile networks. The trigger protocols for mobility are SCCP and MAP. Main part covers the detailed picture of how technically the two types of steering works; the signaling based SoR and over-the-air steering OTA. Both approaches have to take into consideration their official PRD documents when implementing the steering solution. We also presented the key decision factor when adopting a roaming strategy for our outbound subscribers. In the third, last chapter, we analyzed a practical case of steering in the Si.mobil company. Key performance indicators which have to be complied when monitoring the steering service and roaming quality are presented. How the key performance indicators are influenced by our requests on steering platform is explained in last part of this section. The thesis concludes with showing and commenting the actual results of steering.

Keywords:steering of subscriber in roaming, Roaming agreement, Discount agreement, SS7, SoR, OTA, key performance indicators
