发明名称 Systems and methods for allowing IP address handoff for mobile devices
摘要 The present invention is directed to a system and method which mobile devices can be handed from one access point to another while maintaining continuous communication with a network and without changing the device's IP address. In an embodiment, when a device is leaving the air interface range of its home access point, it establishes a connection with an intermediary access point. In an embodiment, the communications from the network are directed to the original access point using the original IP address for the device, and forwarded to the device via the intermediary access point. Communications from the device are routed through the intermediary access point and then either directly to the network, or else through the home access point to the network. The IP address handoff is repeated between intermediary access points until the device either returns to the home access point or ceases communication with the network.
