Abstract: A method and an apparatus for controlling access by an access point, the steps comprising allocating a fixed transmission window to a target station, the transmission window of sufficient size to enable the target station to send a queued frame in response to a poll; establishing a polling schedule; allocating a maximum amount of uplink data based on an application data rate; and; polling the station according to the polling schedule when the uplink data sent by the target station does not exceed an admitted data rate.

Abstract: A method and system for handling roaming mobile nodes in a wireless network. The system uses a Subnet Context Manager to store current Network session keys, security policy and duration of the session (e.g. session timeout) for mobile nodes, which is established when the mobile node is initially authenticated. Pairwise transit keys are derived from the network session key. The Subnet Context Manager handles subsequent reassociation requests. When a mobile node roams to a new access point, the access point obtains the network session key from the Subnet Context Manager and validates the mobile node by computing a new pairwise transient key from the network session key.

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.
