Process-oriented management system for infocommunication networks and services based on TM forum frameworx

Abstract

The existing management systems for telecommunications (Operations Support System/Business Support System, OSSs/BSSs) implement high-tech services by integrating services from different providers, allocating resources, managing services and their quality indexes as well as by predicting and maintaining the demand for services. Due to the constraints connected with formation of new infocommunication services, their flexibility and convenient modification, OSSs/BSSs do not fully match the modern requirements to the management systems of Future Networks (FNs), The management system design methods suggested below involve the process approach based on the Open Digital Architecture (ODA) of TM Forum Frameworx. This paper considers a process model of operational management systems for infocommunication networks and formal statements of associated modeling problems. The basic design principles of such systems are formalized for their analysis as well as an analytical load optimization model is suggested. The rigorous framework of semi-Markovian processes, Laplace transforms and generating functions is used for estimating some processing characteristics of a random flow of service requests
