Abstract

Upravljanje naplatom u mrežama UMTS (Universal Mobile Telecommunications System) i LTE (Long Term Evolution) čini jedan od najbrže rastućih sektora telekomunikacijskog tržišta. Kompleksnost poslužitelja za politiku i kontrolu naplate u mreži LTE (Policy, Charging and Rules Function – PCRF) se povećava zbog potražnje za složenim politikima naplate i stoga testiranje performansi PCRF poslužitelja postaje presudno za poboljšanje ukupne pouzdanosti mreže.
Cilj ovoga rada je dizajnirati i implementirati testno okruženje koje generira poruke protokola Diameter prema različitim modelima matematičkih distribucija te ih propagira prema PCRF poslužitelju. Također je potrebno pružiti funkcionalnost za statističko analiziranje obavljenih Diameter transakcija.
Programsko rješenje prezentirano u ovom radu sastoji se od tri procesa koji međusobno surađuju te čine jednu aplikaciju. Poboljšanja nad programskim rješenjem koje koristi Siemens CVC uključuju mogućnost udaljenog testiranja, generiranje prometa prema distribucijama te stvarno-vremensku analiza prometa.

Abstract (english)

Policy management in the Universal Mobile Telecommunications System (UMTS) and Long Term Evolution networks (LTE) is one of the fastest growing sectors of the telecommunication market. The complexity of Policy, Charging and Rules Function (PCRF) increases due to the demand for more sophisticated policy implementations and therefore performance testing becomes critically important for improving overall network reliability.
The main goal was to develop software solution which could generate Diameter protocol messages following mathematical distributions towards targeted system and also do a statistical analysis on issued Diameter transactions in real time.
The software solution presented in the thesis consists of three processes which work together as one application. Improvements over the Siemens CVC solution include possibility to do remote testing, real time traffic analysis and traffic generation following mathematical distributions.
