Abstract

U ovome radu dan je pregled jezgrenog dijela mobilnih mreža četvrte i pete generacije. Zatim su opisane korisničke baze podataka HSS i UDM, sučelja kojim su povezana s mrežnim entitetima i funkcijama, protokoli koje koriste te formati poruka. Nadalje su analizirane signalizacijske poruke korisničkih baza podataka, kao i interoperabilnost HSS-a i UDM-a. U zadnjem, praktičnom poglavlju ovoga rada analizirane su signalizacijske poruke mobilne mreže 4G pomoću MME simulatora i HSS-a u laboratorijskom okruženju firme Teltech, te signalizacijske poruke mobilne mreže 5G pomoću softvera otvorenog koda Open5GS, implementacije jezgrenog dijela mobilne mreže 5G, te simulatora UERANSIM, simulatora radijskog dijela mobilne mreže i korisničke opreme.

Abstract (english)

This thesis provides an overview of the core networks of fourth and fifth-generation mobile networks. It describes the user databases HSS and UDM, the interfaces through which they are connected to network entities and network functions, the protocols they use, and the message formats employed. Furthermore, the signaling messages of the user databases are analysed, along with the interoperability between HSS and UDM. In the final practical chapter of this paper, signaling messages of the 4G mobile network are analysed using an MME simulator and HSS in the laboratory environment of Teltech company. Additionally, signaling messages of the 5G mobile network are analysed using the open-source software Open5GS, which implements the core network of the 5G mobile network, and UERANSIM, a simulator for the radio part of the mobile network and user equipment.
