  • Patent number: 8848669
    Abstract: A system and method wherein mobile nodes scan both 802.16 and 802.11 radio channels for neighbor access points. A mobile node reports both WiMax and WiFi neighbor access points to its parent access point. A parent access point advertises both WiMax and WiFi neighbor access points to child mobile nodes to facilitate faster roaming and load balancing. A parent WiMax AP can direct a mobile node to roam to a neighbor WiFi access point that has a lighter load or offers enhanced services. As an option, a location tracking protocol is used to determine the location of a mobile node and the mobile node's parent AP advertises neighbor APs that offer services in the mobile node's location.

  • Publication number: 20070160017
    Abstract: An exemplary embodiment providing for one or more improvements includes a method for use in a mobile station operating in a multi-protocol wireless network environment that supports a first wireless communication protocol and a second wireless communication protocol wherein the network environment allows the mobile station to seamlessly roam utilizing the first and second wireless communication protocols. The method includes establishing a first link layer connection using the first wireless communication protocol; and establishing a second link layer connection using the second wireless communication protocol wherein a single mobile identifier, corresponding to the mobile station, is used in the first and second connections.
