摘要： Disclosed is a method for performing handoff in a communication system of access points and a mobile station, where the mobile station is associated with a first access point. The first access point receives a first transmission at a first signal quality from the mobile station and receives a second transmission that indicates a second signal quality at which a second access point is receiving transmissions from the mobile station. The first access point compares the first signal quality with the second signal quality and when the second signal quality is greater than the first signal quality, the first access point signals the second access point to initiate a handoff with the mobile station. The second access point responds by sending a disassociation message to the mobile station to disassociate with the first access point, wherein the disassociation message is addressed as if it originated from the first access point.

摘要： A method and system for wireless data transmission between at least three stations use multiple frequency bands for simultaneous channel communications. The method includes transmitting a Request To Send (RTS) packet from a first station to an intermediate second station over a first frequency band. Two Clear To Send (CTS) packets, which CTS packets include transmission timing information, are then transmitted from the second station simultaneously both to the first station and to a third station. The CTS packet sent to the first station is transmitted over the first frequency band and the CTS packet sent to the third station is transmitted over a second frequency band. A data packet from the first station is then transmitted to the second station. The third station suspends, based on the transmission timing information included in the CTS packets, any unicast transmission to the second station during the transmission of the data packet from the first station to the second station.

摘要： Methods for performing client to client communication in a wireless local area network are disclosed. At an ‘n’ tier client in the wireless local area network, a signaling message from an ‘n−1’ tier client is received wherein the signaling message comprises a first period, a second period, and a third period. Communicating with the ‘n−1’ tier client during the first period and communicating with the ‘n+1’ tier client during the third period. At an access point in the wireless local area network, an association table identifying clients in the wireless local area network is created and a first period for client to client communication based upon the association table and traffic in the wireless local area network is determined where the access point does not communicate with the clients during the first period.

摘要： Methods for delivery of multicast packets in a wireless communication system are disclosed. The methods comprise transmitting a contention free period initiation signal from an access point to the station, transmitting broadcast packets from the access point to the station, transmitting multicast packets from the access point to the station and holding the multicast packets in storage after the transmission, transmitting a contention free period end signal from the access point to the station, determining if a negative acknowledgement message has been received, retransmitting the multicast packets in response to receiving a negative acknowledgment message, and eliminating the multicast packets at a next beacon interval.

摘要： The present invention allows a single access point (“AP”; 100) to support a plurality of devices (102, 104) operating on different frequency bands. During a first period of time, the AP initiates a contention free period at a first frequency. The AP switches from the first frequency to a second frequency, and communicates with devices operating at the second frequency. Periodically during the first period of time, the AP temporarily ceases communication with devices operating at the second frequency to initiate a contention free period at the second frequency, switch from the second frequency to the first frequency, initiate another contention free period at the first frequency, and switch from the first frequency back to the second frequency.

摘要： A system and methods for providing a supplicant access to a communications network are disclosed. An authenticator receives an authentication request at an authenticator (210) from the supplicant. A state is created based on the authentication request at the authenticator (210). The authentication request is relayed towards a prime authenticator (215) where the prime authenticator is connected to an authentication server. Finally, the authenticator (215) receives authentication information from the prime authenticator and fulfills the authentication request using the authentication information.

摘要： A method for providing a mobile device in a packet data network access to a channelized network is disclosed. At a gateway between the two networks, a first channelized network message that is encapsulated in a first IP data packet from the packet data network is received. The first channelized network message is retrieved and reformatted for sending over the channelized network. The gateway then receives a second channelized network message from the channelized network. An identifier of a mobile device associated with the second channelized network message is retrieved and an IP address for the identified mobile device is determined. Then, the gateway encapsulates the second channelized network message into a second IP data packet and sends the encapsulated second channelized network message to the identified mobile device in the packet data network.

摘要： Disclosed are methods for adjustment values. In one embodiment, a cumulative adjustment value is provided in memory, an inbound signal is transmitted to a base station during a random access opportunity, and a relative adjustment value is received from the base station. Then, the relative adjustment value is summed with the cumulative adjustment value to create a new cumulative adjustment value which is stored in the memory. Finally, a subsequent inbound signal is transmitted using the new cumulative adjustment value during a reserved access opportunity.

摘要： Communication units are provided access to a communication system (100) in the following manner. A base station (202) receives, from a requesting communication unit, a request, via a shared inbound communication resource (209), for an available message path (207). When a dual-mode outbound communication resource is operating in a control mode (205), the message path (207), having a first inbound communication resource (204) and the dual-mode outbound communication resource operating in a partial control mode (206), is assigned to the requesting communication unit. Thus, the shared inbound communication resource is consistently available, providing access to the communication system.
