Abstract: System and method for fully transparent IP mobility services for clients in a dynamic LAN Ethernet environment. The functionality within a proxy server, a combination of network address translation, proxy address resolution protocol, and proxy domain name service, allow the proxy server to support and provide full IP client functionality to any IP-enabled network device in any proxy server enabled LAN. The proxy server may be added to an existing Ethernet (or Ethernet-emulated) LAN. Once configured with the necessary subnet range, DNS, and IP pools, the proxy server provides support for any mobile device that enters the LAN.

Abstract: A resource provider subsystem (“RPS”) secures and combines resource access right data with a universal resource locator (URL) as a secure URL in a web page document. The RPS transmits the web page document with the secure URL including resource access right data, to a web access device (“WAD”) via a network. The WAD executes a browser application to display the secure URL of the web page document. A user of the WAD can activate the secure URL to generate a signal. The signal includes the secure URL and is transmitted from the WAD to the resource distribution subsystem (“RDS”). The RDS receives the signal, authenticates the request, and verifies that the resource access right data has not been changed after it was established by the RPS. If the request is authenticated and verified, the RDS uses the resource access right data to determine the rights the WAD and/or user thereof has with respect to the resource.
