    摘要： An IP-based corporate network architecture and method for providing seamless secure mobile networking across office WLAN, home WLAN, public WLAN, and 2.5 G/3 G cellular networks for corporate wireless data users. The system includes Internet roaming clients (IRCs), a secure mobility gateway (SMG), optional secure IP access (SIA) gateways, and a virtual single account (VSA) server. The IRC is a special client tool installed on a mobile computer (laptop or PDA) equipped with a WLAN adaptor and a cellular modem. It is responsible for establishing and maintaining a mobile IPsec tunnel between the mobile computer and a corporate intranet. The SMG is a mobile IPsec gateway installed between the corporate intranet and the Internet. It works in conjunction with the IRC to maintain the mobile IPsec tunnel when the mobile computer is connected on the Internet via a home WLAN, a public WLAN, or a cellular network. The SIA gateway is a special IPsec gateway installed in the middle of the wired corporate intranet and an office WLAN. It works with the IRC to ensure data security and efficient use of corporate IP addresses when the mobile computer is connected to the office WLAN. The VSA server manages authentication credentials for every corporate user based on a virtual single account concept. The Internet Roaming system can provide secure, always-on office network connectivity for corporate users no matter where they are located using best available wireless networks.

    摘要： A protocol framework for a Secure IP Access (SIA) method, and supporting components deployed on IP hosts and IP networks. Using this method, an IP host can establish a secure data channel within an IP network over an insecure shared link while requesting IP address and networking configuration parameters from the IP network. A system administrator can implement strong access control against various attacks that an edge IP network may have to face, such as a denial-of-service attack that exhausts assignable IP addresses. This is a lightweight, scalable, and backward-compatible solution that can improve security performance for public and corporate LANs having open access such as wireless access points and Ethernet jacks.

    摘要翻译： 用于安全IP接入（SIA）方法的协议框架，以及部署在IP主机和IP网络上的支持组件。 使用这种方法，IP主机可以通过不安全的共享链路在IP网络内建立安全数据通道，同时从IP网络请求IP地址和网络配置参数。 系统管理员可以对边缘IP网络可能必须面对的各种攻击实施强大的访问控制，例如耗尽可分配IP地址的拒绝服务攻击。 这是一个轻量级的，可扩展的和向后兼容的解决方案，可以提高具有开放访问权限的公共和公司LAN（如无线接入点和以太网插孔）的安全性能。

    摘要： A method and apparatus to enable IP networking for mobile hosts without requiring changes to be made to the TCP/IP stack in the operating system installed on the mobile hosts. The apparatus is an “intelligent device” that can be installed on or connected to a mobile host, and may comprise a software-only logical module, physical hardware, or a combination of both. To a mobile host, the intelligent device emulates a network interface such as an Ethernet card or a telephone modem. The intelligent device appears to an access network just like any regular IP host connected to the access network through a physical network interface device. The intelligent device handles all mobile networking functions for the mobile host, and may control multiple different physical network interface devices to enable a connection to the “best” access network available to the mobile user at his location.

    摘要： An access interface module includes a first network interface module for interfacing with a first access network and a second network interface module for interfacing with a second access network of a type that is different from the first network. The access module can further include a processor coupled to the first and second network interface modules and a device interface module coupled to the processor for interfacing with a host device.
