Dynamic IP Assignment Method for Wireless Internet Service of Visited Mobile ISP Subscriber on GPRS Network

GPRS망을 방문한 이동 ISP 가입자의 무선 인터넷 서비스를 위한 동적 IP 할당 방법

Abstract

This paper describes problems when visited ISP subscriber gets dynamic IP address in home ISP for wireless internet service on GPRS network. We propose a specific DHCP relay for wireless internet service of visited ISP subscriber on GPRS network. We designed and implemented the specific DHCP relay and installed it in ISP testbed. We show the allocated dynamic IP address using specific DHCP relay for visited ISP subscriber on GPRS network. Now we think it is possible the visited ISP subscriber can access wireless internet service on GPRS network using specific DHCP relay, and UMTS system can be managed IP address for subscriber roaming.

본 논문에서는 GPRS망으로 이동한 이동 ISP 가입자가 GPRS망을 접속하여 무선 인터넷 서비스를 받을 때 필요한 홈 ISP망의 동적 내 주소할당에 대한 문제점을 살펴보고 그 해결 방안으로 홈 ISP망 내 특수(specific) DHCP Relay를 개발하여 운영하는 방법을 제시했다. 실제 GPRS core network testbed와 ISP망을 구축하고 특수 DHCP Relay를 개발해서 GPRS망으로 이동한 이동 ISP 가입자에게 홈 ISP망의 동적 IP 주소 할당을 과정과 결과를 시뮬레이션을 통해 확인하였다.
