Abstract

In the GPRS(General Packet Radio Service) network, the transport layer between SGSN(Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node) is based on IP-Over ATM Network. which means that the connectionless IP traffic is transmitted through connection oriented ATM transport layer. Efficient resource management is needed to perform connection and disconnection of the pertinent VC because of the connectionless IP traffic being passed through ATM transport layer In this paper, Internet Web service traffic model in the GPRS network is applied to the various VC holding Cost Pricing Model. each method is compared through analyzing each VC utilization and setup rate.

제 3세대 이동 통신망인 GPRS(General Packet Radio Service)망에서는 SGSN(Serving GPRS Support Node)과 GGSN(Gateway GPRS Support Node) 사이의 전송계층을 IP-Over-ATM 망을 기반으로 한다. 이는 비연결형(connectionless) IP 트래픽들을 연결지향형(connection-oriented) ATM 전송계층을 통해 전송하는 것을 의미한다. 이때 효율적인 자원관리를 위해 적절한 VC(Virtual Circuit)의 접속과 해제를 수행해야 한다. 본 논문에서는 GPRS망에 인터넷 웹 서비스 트래픽 모델을 다양한 VC holding Cost Pricing Model(LRU, Mean-Variance, Adaptive policy[2])에 적용하였다. 각각의 기법들에서 VC의 이용율(utilization)과 설정율(setup rate)을 분석함으로써 각 기법의 성능을 비교하였다.
