Abstract

U radu je ukratko opisana današnja mobilna telefonija s naglaskom na GSM sustav. Prikazane su metode upravljanja i prometne karakteristike mobilne mreže druge generacije. Izvršena je prilagodba LAG simulacije za mjerenje prometa u GSM mreži. Pojašnjene su osnove teorije automata kroz analizu funkcioniranja više tipova samoučećih automata unutar LAG simulacije. U provedenim eksperimentima testirano je ponašanje mreže u nominalnim prometnim uvjetima te kod preopterećenja i kvarova u mreži. Za kraj su prezentirani rezultati koje koristimo za analizu samoučećih automata i mrežne topologije.

Abstract (english)

The essay shortly describes the present status of mobile telephony with a special emphasis on GSM system. It presents the management methods and traffic features of the 2nd generation mobile network. Adjustment of LAG simulation for measurement of GSM network traffic has been performed. The automata theories have been explained through analysis of functioning of several types of learning automata within LAG simulation. The conducted experiments have tested the network behavior in nominal traffic conditions as well as the conditions of overload and network malfunction. At the end, the results used for analysis of learning automata and network topology has been processed.
