LOCATION-INDEPENDENT PACKET ROUTING AND SECURE ACCESS IN A SHORT-RANGE WIRELESS NETWORKING ENVIRONMENT
First Claim
1. A method of packet routing in a short-range wireless networking environment including one or more portable client devices and one or more application servers, comprising:
- transmitting a packet from an application server to a portable client device, wherein the transmitted packet is received at a home agent associated with the client device;
forwarding, by the home agent, the received packet to a foreign agent through which the client device is currently communicating;
receiving, by the foreign agent, the forwarded packet; and
forwarding, by the foreign agent, the received forwarded packet to the client device.

Abstract
The present invention provides methods, systems, and computer program instructions for providing location-independent packet routing and secure access in a wireless networking environment (such as that encountered within a building), enabling client devices to travel seamlessly within the environment. Each client device uses a constant address. An address translation process that is transparent to the client and server is automatically performed as the device roams through the environment, enabling efficient client migration from one supporting access point to another. The secure access techniques provide user-centric authentication and allow policy-driven packet filtering, while taking advantage of encryption capabilities that are built in to the hardware at each endpoint.
