Abstract

Kako bi se omogućio daljnji razvoj poslovnih modela na današnjem konkurentnom telekomunikacijskom tržištu, koje je okarakterizirano složenim konvergentnim heterogenim okruženjem, potrebno je ostvariti nadzor kvalitete usluge što predstavlja izazov za telekomunikacijske operatore prilikom transformacije njihovih operacijskih procesa prema proaktivnoj organizaciji. U skladu s TMF NGOSS standarizacijskim okvirom predložena je funkcionalna arhitektura za upravljanje kvalitetom usluge s kraja na kraj mreže kao integracijsko rješenje koje nadopunjuje postojeće OSS/BSS sustave te pruža automatizaciju poslovnih proces upravljanja i omogućuje pogled na kvalitetu usluge sa stanovišta različitih zainteresiranih strana. Za učinkoviti pristup implementaciji nadzora kvalitete usluge predložena je konkretna metodologija za modeliranje kvalitete usluge, definiranje ključnih pokazatelja performansi usluge te identifikaciju nadzornih i mjernih podataka za populaciju modela usluge. Tako definirana metodologija postavlja fokus na uslugu i/ili kupca te omogućuje definiranje okvira usluge prilikom modeliranja složenih usluga u okruženju s više pružatelja usluga s više različitih tehnologija. U laboratorijskom okruženju simulirana je predložena integracijska arhitektura, te je korištenjem predložene metodologije kreiran i implementiran model usluge.

Abstract (english)

QoS monitoring presents an important challenge for operators as they transform their operational processes towards proactive organization and facilitate further business models in today competitive telecommunication landscape and complex convergent heterogeneous environments. Following on standardization frameworks such as TMF NGOSS, a functional end-to-end service assurance architecture for Service Quality Management is proposed as integration solution that complements the existing OSS/BSS systems, provides automation for business processes and enables view on QoS from different stakeholder perspectives. For effective service assurance approach implementation, a “top-down” straightforward methodology is described that provides Quality of Service modeling, KQI/KPI definition and identification of monitoring and measurement data for service model population. Such methodology enables service and/or customer focus as well as scope management that is necessary to obtain when modeling complex services in multi-provider and multi-technology environment. Proposed functional service assurance architecture has been simulated in laboratory environment and was used to implement service model that was created based on proposed methodology.
