Abstract

UMTS network, evolved from GSM, includes packet core network that consists of SGSNS and GGSNs. Service providers should consider subscriber mobility, location registration, and subscriber distribution when designing packet core networks and network elements. Since one of the major traffic sources for IMT-2000 will be data which has bursty characteristics, new design guidelines for dimensioning of SGSN and GGSN should be proposed under various constraints of system parameters. In this paper, we first evaluate the performance of signaling traffic for packet call subscribers. After that, we also obtain the impact of bursty data traffic on the SGSN and GGSN by simulation, and suggest new dimensioning guidelines for packet core network of UMTS under various environments.

GSM에서 발전한 UMTS 망의 경우 SGSN(Serving GPRS Support Node)과 GGSN(Gateway GPRS Support Node)을 중심으로 한 패킷 핵심 망을 포함하고 있다. 이러한 UMTS 망에서는 가입자 이동성, 위치 등록, 가입자 분포 등을 고려하여 망을 설계하고 장비의 제원을 정하여야 한다. 또한 향후 IMT-2000의 주요 트래픽이 데이터이기 때문에 인터넷 데이터 트래픽의 특성인 burstiness를 반영한 SGSN과 GGSN의 설계 기준이 마련되어야 하고 제약적인 시스템 조건 하에서 성능의 변화를 살펴보아야 한다. 이에 본 논문에서는 먼저 패킷 호 가입자의 신호 트래픽을 분석하며 이에 따른 망 성능 변화를 살펴보고, burstiness 특성을 가지는 패킷 데이터가 패킷 코아 망에 미치는 영향을 다양한 환경 하에서 시뮬레이션으로 분석한 뒤 UMTS 망에 새로이 추가하는 두개의 주요 망 요소인 SGSN과 GGSN의 요구 성능을 구하여 그 결과를 바탕으로 새로운 패킷 모드 핵심 망의 설계 기준을 제시하도록 한다.
