A UMTS network architecture

Abstract

This paper proposes a Functional Architecture and a corresponding Network Architecture for the Universal Mobile Telecommunication System (UMTS). Procedures like call handling, location management, and handover are considered. The architecture covers the domestic, business, and public environments. Integration with existing and forthcoming networks for fixed communications is anticipated and the Intelligent Network (IN) philosophy is applied. 2 Introduction UMTS is aimed to be a system capable of providing a diversity of mobile services (up to 2 Mbps) as now being offered by cordless, cellular, and (dedicated) paging systems. UMTS should be operational in domestic, business, vehicular, and multi-operator public environments. UMTS can be considered as the successor of second generation mobile communication systems like GSM, DECT, and ERMES [3]. Within RACE project 2066 MoNeT (Mobile NeTwork) the network aspects of UMTS are being studied. Major activities within MoNeT are, amongst other...
