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 includes a gateway wired to an IP network; and
a second level wired to said first level, said second level operable with a plurality of mobile stations and said second level is comprised of at least two access points operable with a respective plurality of mobile stations;
said first level maintaining, for each of plurality of mobile stations operable with said second level, a wireline address for said mobile station within said second level, said first level, for each mobile station associated with said second level by one of said at least two access points, an address of said access point to which said mobile station is associated;
said second level maintaining, for each of the plurality of mobile stations operable with said second level, a wireless address for said mobile station;
a distribution system for coupling said gateway to said at least two access points, said distribution system wired to said gateway and said at least two access points; and
a WiARP server wired to said gateway, said WiARP server maintaining, for each mobile station associated with said second level, a MAC address of said access point with which said mobile station is associated.

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.

14. For a wireless network comprised of at least two access points operable to interface with a select of a plurality of mobile stations, 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 the select of the plurality of mobile stations; said gateway forwarding an IP data packet bearing said IP address to said access point having said MAC address linked to said IP address; said access point delivering said forwarded IP data packet to said mobile station having said IP address; maintaining a first data store at said gateway, said first data store comprised of IP addresses for each mobile station associated with one of said at least two access points of said wireless network and MAC addresses for each one of said at least two access points, each said IP address of a mobile station maintained in said first data store is linked to said MAC address for said access point with which said mobile station is associated receiving, at said gateway, an IP data packet form said IP network; determining an IP address of said received IP data packet; determining if said first data store includes an IP address matching said determined IP address; and if said first data store includes an IP address matching said determined IP address, forwarding said received IP data packet to said access point having said MAC address linked to said matching IP address. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A hierarchical wireless network, comprising:
-
a first level, said first level includes a gateway wired to an IP network; and a second level wired to said first level, said second level operable with a plurality of mobile stations and said second level is comprised of at least two access points operable with a respective plurality of mobile stations; said first level maintaining, for each of the plurality of mobile stations operable with said second level, a wireline address for said mobile station within said second level, said first level, for each mobile station associated with said second level by one of said at least two access points, an address of said access point to which said mobile station is associated; said second level maintaining, for each of the plurality of mobile stations operable with said second level, a wireless address for said mobile station; a distribution system for coupling said gateway to said at least two access points, said distribution system wired to said gateway and said at least two access points; and a WiARP server wired to said distribution system, said WiARP server maintaining, for each mobile station associated with said second level, a MAC address of said access point with which said mobile station is associated. - View Dependent Claims (27)
