Universal Mobile Telecommunication System (UMTS) as an International Mobile Telecommunication (IMT) 2000 system is designed to provide high rate data services to mobile users. Recently, most wireless services such as Internet access and multimedia service are changing into packet-oriented ones. In this paper, a commercial SGSN system, model name Generex-2000 SGSN, for UMTS packet service network was developed and examined. Requirements from several UMTS service providers are analyzed and applied to the SGSN system development. How much performance and capacity that the SGSN should have as a commercial system are presented. The developed SGSN system was proved to have enough performance and high capacity as well as various service features through a benchmarking test held by a Korean 3G service provider from December 2001 to June 2002. © Springer-Verlag Berlin Heidelberg 2003.
