Abstract

This paper proposes an enterprise-oriented WLAN/3G network integration solution, called the Internet Roaming system. Differing from other operator-oriented WLAN/3G network integration solutions, the Internet Roaming system is a practical IP-based corporate network architecture that provides seamless internetworking across office WLAN, home WLAN, public WLAN, and 2.5G/3G cellular network for corporate wireless data users. An Internet Roaming system may have four building blocks. They are IRC (Internet Roaming Client), SMG (secure mobility gateway), SIA (Secure IP Access) gateway, and VSA (virtual single account) server. The IRC is a special client tool (software or hardware) installed on a wireless data device. It provides a secure mobile IP connection from the wireless data device to the corporate network transparent to the operating system of the wireless data devices. The SMG is a mobile IPsec gateway installed on the corporate core network facing the Internet. It works with the IRC to maintain a secure mobile IP connection when the wireless data device is connected on the Internet through a home WLAN, a public WLAN, or a cellular network. The SIA server is a special IPsec gateway installed on the corporate intranet where office WLAN is installed. It works with the IRC to assure the security of office WLAN while improving the routing efficiency for users computers. The VSA server manages the IRC, SMG, and SIA servers.
