Abstract:
1. A method for routing data comprising: determining a need to support at least one communication need of a mobile station; acquiring, by a first wireless access point of a subnet that comprises a plurality of wireless access points, a first Internet Protocol address used in association with the mobile station by a second wireless access point of the plurality of wireless access points; automatically transmitting, by the first wireless access point, a gratuitous Address Resolution Protocol message to a router that shares the same subnet as the wireless access point, to thereby cause the router to correlate the first Internet Protocol address to a Medium Access Control address for the first wireless access point; automatically transmitting a registration request to a network element that is remote to the subnet, wherein the registration request presents a second Internet Protocol address as a home address for the mobile station and the first Internet Protocol address as a care-of-address for the mobile station for use by the network element to route data to the mobile station; receiving, by the first wireless access point from the router and using the Medium Access Control address, data intended for eventual delivery to the mobile station.
