Hierarchical wireless network and an associated method for delivering IP packets to mobile stations
First Claim
1. A hierarchical wireless network, comprising:
- a first level, said first level configured for wired coupling to an IP network; and
a second level wired to said first level, said second level configured for wireless association with a plurality of mobile stations;
said first level maintaining, for each mobile station associated with said second level, a wireline address for said mobile station within said second level; and
said second level maintaining, for each mobile station associated with said second level, a wireless address for said mobile station.

Abstract
A hierarchical wireless network is comprised of two levels, a first level configured for wired coupling to an IP network and comprised of a gateway configured for wired coupling to the IP network, a WiARP server and a data store; and a second level, wired to the first level by a distribution system, and comprised of at least two access points, each configured for wireless association with a respective plurality of mobile stations and having a WiARP proxy residing therein. For each mobile station associated with the second level, the WiARP server maintains an IP address of the mobile station and a MAC address for the access point with which the mobile station is associated. Conversely, each WiARP proxy maintains, on behalf of the associated access point, IP and MAC addresses for each mobile station associated therewith.

20. For a wireless network comprised of at least two access points with which mobile stations may associate, a gateway to an IP network and a distribution system coupling said at least two access points to said gateway, a method for unicast delivery of IP data to mobile stations associated with one of said at least two access points, comprising:
-
linking an IP address for a mobile station to a MAC address for an access point with which said mobile station is associated;
said gateway forwarding an IP data packet bearing said IP address to said access point having said MAC address linked to said IP address; and
said access point delivering said forwarded IP data packet to said mobile station having said IP address. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
